*   `pedantic`

    Turns on all of GCC's warnings and portability checks.  Good for
    checking changes before making a public release.

*   `bat`

    Asks `cmd.exe` to run `bootstrap.bat` for you. This is useful when
    using Cygwin just as a command shell in preference to `cmd.exe`, as
    opposed to using Cygwin to build MySQL++ using its native tools.





    Passing 'bat' stops all command line processing in the bootstrap
    script, so if you also pass some of the other options, make "`bat`"
    last.  The only options that affect the built project files and
    `Makefiles` work are the no* ones.




















*   `configure` script options

    As soon as the bootstrap script sees an option that it doesn't
    understand, it stops processing the command line.  Any subsequent
    options are passed to the `configure` script. See
    [README-Unix.txt][rmu] for more on `configure` script options.

*   `pedantic`

    Turns on all of GCC's warnings and portability checks.  Good for
    checking changes before making a public release.

*   `bat`

    Runs `bootstrap.bat` via `cmd.exe` for you, passing along equivalent
    options to any of the "*no*" options you give before it.


    None of the other options above have any effect on the generated
    build system files when you give "`bat`".  If you need those
    features, leave this option off.

    Passing `bat` stops all command line processing in the `bootstrap`
    script, so if you also pass some of the other options, "`bat`" must


    be last.
    
    The `bootstrap.bat` script is useful only when you intend to build
    MySQL++ with MinGW or Visual C++, and you are using Cygwin only as a
    command line environment.  If you intend to build MySQL++ with
    Cygwin's GCC toolchain, you must not give this option, else you will
    not end up with the necessary build system files.

    One advantage of this feature is that the commands necessary to
    achieve a given effect with `bootstrap.bat` when run via `bootstrap`
    are shorter than when you run the batch file directly.

    Another advantage is that this low-strength version of the bootstrap
    script runs faster than the full-strength form, because it produces
    fewer files.

    Finally, running `bootstrap.bat` indirectly like this lets you avoid
    using `cmd.exe`, a command shell greatly inferior to any of those
    available for Cygwin.

*   `configure` script options

    As soon as the bootstrap script sees an option that it doesn't
    understand, it stops processing the command line.  Any subsequent
    options are passed to the `configure` script. See
    [README-Unix.txt][rmu] for more on `configure` script options.

The installation procedure depends on the compiler you use to build

MySQL++ and the OS you build it on.  There are platform-specific
instructions for all popular platforms:

	README-Cygwin.txt     - for Cygwin
	README-Linux.txt      - for Linux
	README-Mac-OS-X.txt   - for Mac OS X
	README-MinGW.txt      - for MinGW

	README-Solaris.txt    - for Solaris
	README-Visual-C++.txt - for Visual C++


If you're on some Unix variant (Linux, OS X, *BSD, Solaris, Cygwin...)
there are additional general instructions in README-Unix.txt.


See the main README.txt file for high-level instructions that apply
to all platforms MySQL++ works on.

		  GNU LESSER GENERAL PUBLIC LICENSE
		       Version 2.1, February 1999

 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

[This is the first released version of the Lesser GPL.  It also counts
 as the successor of the GNU Library Public License, version 2, hence
 the version number 2.1.]






			    Preamble





  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.



  This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it.  You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.


  When we speak of free software, we are referring to freedom of use,
not price.  Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.


  To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights.  These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.

  For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you.  You must make sure that they, too, receive or can get the source
code.  If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it.  And you must show them these terms so they know their rights.

  We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.


  To protect each distributor, we want to make it very clear that












there is no warranty for the free library.  Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be

introduced by others.
 

  Finally, software patents pose a constant threat to the existence of
any free program.  We wish to make sure that a company cannot

effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder.  Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.


  Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License.  This license, the GNU Lesser
General Public License, applies to certain designated libraries, and

is quite different from the ordinary General Public License.  We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.


  When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library.  The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom.  The Lesser General
Public License permits more lax criteria for linking other code with
the library.

  We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License.  It also provides other free software developers Less
of an advantage over competing non-free programs.  These disadvantages
are the reason we use the ordinary General Public License for many
libraries.  However, the Lesser license provides advantages in certain
special circumstances.

  For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard.  To achieve this, non-free programs must be
allowed to use the library.  A more frequent case is that a free
library does the same job as widely used non-free libraries.  In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.

  In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software.  For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.

  Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.

  The precise terms and conditions for copying, distribution and
modification follow.  Pay close attention to the difference between a
"work based on the library" and a "work that uses the library".  The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
 
		  GNU LESSER GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".

  A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.

  The "Library", below, refers to any such software library or work
which has been distributed under these terms.  A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language.  (Hereinafter, translation is
included without limitation in the term "modification".)

  "Source code" for a work means the preferred form of the work for
making modifications to it.  For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.

  Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it).  Whether that is true depends on what the Library does
and what the program that uses the Library does.
  
  1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.

  You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
 
  2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

    a) The modified work must itself be a software library.

    b) You must cause the files modified to carry prominent notices
    stating that you changed the files and the date of any change.

    c) You must cause the whole of the work to be licensed at no
    charge to all third parties under the terms of this License.

    d) If a facility in the modified Library refers to a function or a
    table of data to be supplied by an application program that uses
    the facility, other than as an argument passed when the facility
    is invoked, then you must make a good faith effort to ensure that,
    in the event an application does not supply such function or
    table, the facility still operates, and performs whatever part of
    its purpose remains meaningful.

    (For example, a function in a library to compute square roots has
    a purpose that is entirely well-defined independent of the
    application.  Therefore, Subsection 2d requires that any
    application-supplied function or table used by this function must
    be optional: if the application does not supply it, the square
    root function must still compute square roots.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.

In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

  3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library.  To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License.  (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.)  Do not make any other change in
these notices.
 
  Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.

  This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.

  4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.

  If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.

  5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library".  Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.

  However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library".  The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.

  When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library.  The
threshold for this to be true is not precisely defined by law.

  If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work.  (Executables containing this object code plus portions of the
Library will still fall under Section 6.)

  Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
 
  6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.

  You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License.  You must supply a copy of this License.  If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License.  Also, you must do one
of these things:

    a) Accompany the work with the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work (which must be distributed under
    Sections 1 and 2 above); and, if the work is an executable linked
    with the Library, with the complete machine-readable "work that
    uses the Library", as object code and/or source code, so that the
    user can modify the Library and then relink to produce a modified
    executable containing the modified Library.  (It is understood
    that the user who changes the contents of definitions files in the
    Library will not necessarily be able to recompile the application
    to use the modified definitions.)

    b) Use a suitable shared library mechanism for linking with the
    Library.  A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the user's computer system,
    rather than copying library functions into the executable, and (2)
    will operate properly with a modified version of the library, if
    the user installs one, as long as the modified version is
    interface-compatible with the version that the work was made with.

    c) Accompany the work with a written offer, valid for at
    least three years, to give the same user the materials
    specified in Subsection 6a, above, for a charge no more
    than the cost of performing this distribution.

    d) If distribution of the work is made by offering access to copy
    from a designated place, offer equivalent access to copy the above
    specified materials from the same place.

    e) Verify that the user has already received a copy of these
    materials or that you have already sent this user a copy.

  For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it.  However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.

  It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system.  Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
 
  7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:

    a) Accompany the combined library with a copy of the same work
    based on the Library, uncombined with any other library
    facilities.  This must be distributed under the terms of the
    Sections above.

    b) Give prominent notice with the combined library of the fact
    that part of it is a work based on the Library, and explaining
    where to find the accompanying uncombined form of the same work.

  8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License.  Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License.  However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.

  9. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Library or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.

  10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
 
  11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all.  For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.

If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

  12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded.  In such case, this License incorporates the limitation as if
written in the body of this License.

  13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number.  If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation.  If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
 
  14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission.  For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this.  Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing

           How to Apply These Terms to Your New Libraries

  If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change.  You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).

  To apply these terms, attach the following notices to the library.  It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

    <one line to give the library's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This library is free software; you can redistribute it and/or
    modify it under the terms of the GNU Lesser General Public
    License as published by the Free Software Foundation; either
    version 2.1 of the License, or (at your option) any later version.

    This library is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
    Lesser General Public License for more details.

    You should have received a copy of the GNU Lesser General Public
    License along with this library; if not, write to the Free Software
    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA

Also add information on how to contact you by electronic and paper mail.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary.  Here is a sample; alter the names:

  Yoyodyne, Inc., hereby disclaims all copyright interest in the
  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

  <signature of Ty Coon>, 1 April 1990
  Ty Coon, President of Vice

That's all there is to it!

Linux is basically Unix, so README-Unix.txt covers the generic bits.
I'll just cover a few of the issues specific to Linux here.




Prerequisite: Install the MySQL Development Files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    MySQL++ is built on top of the MySQL C API library, so it needs the
    C API development files to build against.  Most distributions of
    the MySQL server for Linux don't come with these development files;
    they're packaged separately.  This is because you don't actually
    need the server on your development machine, though it's often more
    convenient to use a local server than a remote one, for testing.




    There are about as many different ways to get the C API development
    files on your system as there are major Linux distributions.
    More actually, because you also have the option of the official
    MySQL binaries from mysql.com:



        http://dev.mysql.com/downloads/mysql/5.0.html#linux


    For RPM-based distributions, MySQL comes in several different
    packages.  You need at least the -devel and the -shared packages
    to build MySQL++.


    The other binary distributions seem to come in just a single file,
    presumably with everything included.


    You can also build from source, in which case you will also get
    the entire kit and kaboodle.



    MySQL frequently comes with Linux distributions as well.  If your
    distribution doesn't come with at least MySQL v4.1, I recommend
    using the official MySQL.com packages instead.  MySQL++ can be
    made to run with 4.0 and older, but it takes some work.


    On Red Hat type systems with yum, say:


        # yum install mysql-devel

    If you want to use rpm directly, you need that package and probably
    the base mysql package as well.

    On Debian/Ubuntu type systems, say:


        $ sudo apt-get install libmysqlclient15-dev


    The version number is the ABI version of the MySQL C API library.
    ABI version 15 corresponds to MySQL version 5.0, the recommended
    stable version as of this writing.

        


Dealing with the Dynamic Linker, ld.so
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    ld.so is a system-level program on Linux which is used to run any
    program that uses shared libraries (lib*.so).  Its job is to find
    the libraries and link them to the base executable so it will run.

    Because ld.so only looks in a few places for libraries on most
    systems, a common problem is a program that builds without error
    but won't run, complaining about libmysqlpp.SOMETHING.

    There are a number of ways to deal with this.

    First, you could just configure MySQL++ to install under /usr
    instead of /usr/local, like system-provided packages:

        $ ./configure --prefix=/usr

    This isn't recommended practice when building packages from source,
    but it does work.

    Second, you can add the MySQL++ library directory to the
    LD_LIBRARY_PATH environment variable.  This works like the shell's
    PATH variable: a colon-separated list of directories to search.
    This is best when the installation directory is something totally
    uncommon, or you don't have root permissions on the box so you
    can't do the next option.

    Finally, the most robust way to tell ld.so about a nonstandard
    library directory is to put it in /etc/ld.so.conf or in one of
    the files included from there.  Then, run ldconfig as root to
    rebuild the cache file ld.so uses to find libraries in these
    nonstandard directories.  Running ldconfig isn't necessary for
    the previous two methods.

Building MySQL++
~~~~~~~~~~~~~~~~
    There are two major ways to build MySQL++: from the command line, or
    from within the Xcode IDE.





    MySQL++ has its roots in Unix and Linux, like MySQL itself.  As a
    result, the most well-supported way to build MySQL++ is from the
    command line, or Terminal as Apple likes to call it.  See
    README-Unix.txt for the generic instructions.  Further Mac-specific
    details are given elsewhere in this file.

    The option to build MySQL++ from within Xcode is new.  We added
    experimental support for it in 3.0.0, but it didn't actually get
    tested and debugged until 3.1.0.  It may still be buggy, and over
    time it's more likely to break again than the command line method,
    simply because it receives less testing during development.  Even
    fully functional, it is less flexible than building from the command
    line; Xcode's project system cannot match the power available within
    the autotools build system.


    If you try the Xcode method and find that it doesn't work, the
    easiest way around that roadblock is to build from the command line
    instead.  If you're the adventurous sort and want to contribute to
    the development of MySQL++, see the file HACKERS.txt for more info
    on fixing the source file used as input in the project file
    generation process.  We don't want fixed project files, we want a
    process that lets us consistently generate correct project files.










Prerequisite: Install the MySQL Development Files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    MySQL++ is built on top of the MySQL C API library, so for MySQL++
    to build, it needs at least that library and its header files
    installed.  You don't need the server itself installed on your
    development machine, though it's often helpful anyway, for testing.
    There are many suitable sources:






    - The simplest option is to download the MySQL server DMG from
      mysql.com.  In addition to the C API files you absolultely must
      have, this gives you a nice Mac-like installation procedure and a
      preference pane for bringing the server up and down and setting it
      to start on system boot.



    - If you really only want the C API development files, MySQL offers
      them separately as Connector/C.  As of this writing, you get the
      files as a tarball, and you have to copy its contents to some
      suitable location on your hard drive.  If you're using Xcode to
      build MySQL++, you'll want to put them under /usr/local/mysql.
      MySQL++'s command line build system is far more tolerant, looking
      there and in many other typical locations.



    - If you use Fink, you can install the C API files with:


      $ fink install mysql15-dev

      
      If you also want a local MySQL server, say this instead:


      $ fink install mysql mysql15-dev


    
    - From MacPorts, http://macports.org.  I have zero information on
      this other than that it's theoretically possible for it to work.
      If you figure out how to make it work, please post the method
      to the mailing list so I can update this document.






Dealing with the 64-Bit Transition in Snow Leopard
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Xcode for Snow Leopard installs two independent versions of the GNU
    Compiler Collection.  The default is GCC 4.2, and it is set up to
    build 64-bit executables by default, even if your system is booted
    into 32-bit mode.  You also get GCC 4.0, which builds 32-bit
    executables by default.  On top of that, you have the confusion
    added by Apple's decision to make all 64-bit capable machines boot
    into 32-bit mode by default, except for the Xserves.

    The first symptom most people run into as a result of this mess is
    that the "configure" script fails, yelling something about being
    unable to link to libmysqlclient, the MySQL C API client library.
    It's because the library was probably built as a 32-bit executable
    and you're using the default compiler which tries to build a 64-bit
    test executable against this library and fails.

    There are many ways out of this tarpit.  Here are the ones I prefer:

    First, you can force GCC 4.2 to build 32-bit binaries:



        ./configure CFLAGS=-m32 CXXFLAGS=-m32 LDFLAGS=-m32 --other-flags-here








    Second, you can make the MySQL++ build system use GCC 4.0 instead:

        ./configure CC=gcc-4.0 CXX=g++-4.0 --other-flags-here

    Last, you could just take Apple's implied advice and start booting
    your Mac into 64-bit mode, if it will support it.  Here's an article
    that goes into all the details:


        http://macperformanceguide.com/SnowLeopard-64bit.html

    I'm aware of other solutions to the problem, but I expect one among
    these will work for you.


Making Universal Binaries
~~~~~~~~~~~~~~~~~~~~~~~~~
    By default, the command line build system will generate libraries
    that only work with the platform you build MySQL++ on.  It can be
    convinced to build "universal" binaries instead by configuring
    the library like so:

    $ ./configure --disable-dependency-tracking \
            CXXFLAGS='-arch ppc -arch i386'

    This builds the library for the two 32-bit OS X architectures, and
    is what most people have traditionally thought of as "universal".
    However, you may also want a 64-bit build, meaning there are four
    different architectures, and thus four -arch flags needed:

    $ ./configure --disable-dependency-tracking \
            CXXFLAGS='-arch ppc -arch ppc64 -arch i386 -arch x86_64'

    These are single commands, with the line broken to keep the line
    lengths in this document reasonable.

    The first command doubles build time relative to the default
    configuration, and the second quadruples it.  It also makes the
    resulting binaries larger, which increases the amount of time
    it takes to start a program.  Build MySQL++ like this only if
    you must.

    The --disable-dependency-tracking flag is necessary because,
    when building universal binaries, it has to rebuild each source
    module multiple times, which confuses the logic that tries to tell
    when a given module needs rebuiding based on its dependencies on
    other files.

Prerequisite: GCC Version
~~~~~~~~~~~~~~~~~~~~~~~~~
    If your MinGW version isn't using at least GCC 3.4.5, it needs
    to be updated.  Older versions are known to not work with MySQL++.

    As of MySQL++ 3.1.1, the required version might need to be even
    newer, as we are now depending on improvements to the MinGW linker
    which probably don't go back that far.


Prerequisite: MySQL C Development Files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    MySQL++ is built atop MySQL's C API library.  The easiest way to
    get that is to install Connector/C on your development system,
    which you can download from mysql.com.  The distribution assumes
    these files are in:

        C:\Program Files\MySQL\MySQL Connector C 6.1\

    There are a number of reasons why that path may not work for you:

      - You have a newer version of Connector/C installed

      - You're on a 64-bit system, but have the 32-bit versions of
        Connector/C and MinGW installed and wish to build a 32-bit
        binary.  In that case, the path will look like this instead:

          C:\Program Files (x86)\MySQL\MySQL Connector C 6.1\

      - You may have the MySQL Server on your system and installed the
        development files along with it, and therefore don't want to
        install Connector/C separately.  In that case, the path will
        look like this instead:

          C:\Program Files\MySQL\MySQL Server 5.6\
    
    Regardless of the reason you have for changing this path, there are
    two ways that work:

      - The easy way is to do a global search and replace on the path
        in Makefile.mingw.  This is a generated file, but if that's the
        only change to MySQL++ you need, it works fine.

      - If you're doing deeper work on MySQL++, you should change the
        MYSQL_WIN_DIR variable at the top of mysql++.bkl instead.
        
        Having done that, you can generate Makefile.mingw from that
        file using the Windows port of Bakefile (http://bakefile.org/):
        
          bakefile_gen -f mingw


Building the Library and Example Programs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    With the prerequisites above taken care of, you can build MySQL++
    with this command:

        mingw32-make -f Makefile.mingw

    Notice that we're using the MinGW-specific version of GNU make, not
    the Cygwin or MSYS versions.  Many things will break otherwise: path
    separator handling, shell commands used by the Makefile, etc.

    Speaking of Cygwin and MSYS, if you have either these or any other
    Unix emulation environment installed, be sure their executables
    aren't in the PATH when building MySQL++.  MinGW's version of GNU
    make does some funny things if it thinks it's running in the
    presence of Unixy tools, which will break the MySQL++ build.

    Once the library is built, you should run the examples.  At minimum,
    run resetdb and simple1.

    Once you're satisfied that the library is working correctly, you can
    run install.hta to automatically install the library files and
    headers in subdirectories under c:\mysql++.


Cygwin and MinGW Coexistence
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    It's possible to have both Cygwin and MinGW installed and build
    with the MinGW tools without interference from the Cygwin bits.
    The main thing you have to take care of is that MinGW's bin
    directory must precede the Cygwin bin directory in the PATH,
    so that its tools are found first.  If you use Cygwin's bash
    as a command shell in preference to the DOS-like cmd.exe, you
    can use this shell script to temporarily set the environment to
    "MinGW mode" and make it easy to get back to "Cygwin mode":

        #!/bin/sh
        PATH=/c/mingw/bin:/c/windows:/c/windows/system32:/c/cygwin/bin
        echo "Say 'exit' to leave MinGW shell and restore Cygwin environment."
        /usr/bin/bash --rcfile ~/.mingwrc

    I recommend having at least this in the ~/.mingwrc file:

        alias make=mingw32-make
        PS1='MinGW: \W \$ '

    The prompt change reminds you that you are in a sub-shell set up for
    MinGW.  The alias for 'make' ensures you don't accidentally run
    Cygwin's make, which won't work with Makefile.mingw.  We could just
    leave /c/cygwin/bin out of the environment, but there are Cygwin
    tools we want access to, like vim.  As long as all the MinGW ones
    override those Cygwin also provides, we don't need to worry about
    having both in the PATH.  Besides, having the alias is nice for
    those who have 'make' committed to muscle memory.


Building on Linux
~~~~~~~~~~~~~~~~~
    You might wish to build MySQL++ with MinGW because you're
    not actually running Windows, but need Windows executables.
    The thought being that this lets you use GCC, the same compiler
    you're probably using to make native executables.  There are
    indeed ways to make this work.

    The most "native" way to do this is to run MinGW under Wine.
    Leonti Bielski provided these instructions:

        1. Install MinGW through Wine:

           $ wine MinGW-5.1.6.exe

        2. Add the MinGW directory to Wine's PATH with Wine regedit:

           http://winehq.org/site/docs/wineusr-guide/environment-variables

        3. Install MySQL under Wine, or at least unpack the Windows
           ZIP file version of MySQL in a place where Wine can find it.
           You don't need to run a Windows MySQL server under Wine.
           We're only doing this to get the MySQL C API library and
           its headers, which MySQL++ builds against.  The resulting
           MinGW build of MySQL++ can talk to a native MySQL server
           out in Wine's host environment or on some other machine.

        4. Modify Makefile.mingw to match the install location for
           the MySQL C API files.

        5. Build MySQL++ with:
        
           $ wine mingw32-make -f Makefile.mingw

    Another way is to build a Windows virtual machine, such as with
    VMware or VirtualBox.  In that case, you'd use the regular build
    instructions at the top of this document.

    You might think to avoid the need for Wine or Windows by use of a
    MinGW cross-compiler:

        $ ./configure --target=mingw32
        $ make

    Unfortunately, that currently doesn't work.

    The reason is that our autoconf build system assumes a
    typical POSIX type target, which MinGW is not.  We made this
    assumption because we have a perfectly good MinGW build option,
    Makefile.mingw.  But, that also won't work on a POSIX system
    because that Makefile assumes external commands run under cmd.exe,
    not some Unixy shell.  Thus the advice to build with Makefile.mingw
    under Windows or something sufficiently close to it.

    If you really wanted to, you could extend the autoconf build system
    to make it realize when it's being used to cross-compile for MinGW.
    Patches thoughtfully considered; see HACKERS.txt.

For the most part, Solaris is just another Unix variant as far as
MySQL++ is concerned.  See README-Unix.txt for most of what you need
to know to build and use MySQL++.


Prerequisite: Install the MySQL Development Files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    MySQL++ is built on top of the MySQL C API library, so it needs the
    C API development files to build against.

    With the current version of Solaris, at least, a MySQL package
    is included on the operating system disk, but not installed
    by default.  To install it, oull down the GNOME System menu,
    go to Administration, and then to Package Manager.  Search for
    "mysql5" and install those packages.  While there, you may also
    need to install the gcc packages, if you haven't done that already.
    I'm not sure, but you may need to install Perl as well.

    Don't search for just "mysql" in Package Manager, as that will also
    bring up legacy MySQL 4.0 packages.  MySQL++ may build against 4.0
    still; it's been a while since we've tested it.  What is certain
    is that the examples won't run against 4.0 without modification,
    as they assume the availability of UTF-8 character set support,
    which was added in 4.1.

    It's no doubt possible to use the official binaries from mysql.com
    instead, or to build from source.  We don't do that ourselves,
    though, and don't have reports from those who have, so we can't
    advise on how to do it.


C API Development File Directories
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Sun's MySQL package installs the development files in relatively
    uncommon locations.  The libraries are in /usr/mysql/lib/mysql,
    and the headers are in /usr/mysql/include/mysql.  Way to be
    redundant, guys. :)

Platform Variations
~~~~~~~~~~~~~~~~~~~

    This file only covers details common to all Unix variants
    supported by MySQL++.  For platform-specific details, see the
    file appropriate to your OS:


        README-Cygwin.txt
        README-Linux.txt
        README-Mac-OS-X.txt
        README-Solaris.txt


    There are no special instructions for any other Unix flavors.



Building the Library and Example Programs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    MySQL++ uses GNU autoconf, so you can build it with the standard
    commands:

    $ ./configure
    $ make
    $ su
    # make install




Configure Options
~~~~~~~~~~~~~~~~~
    The configure script takes several interesting options. Say:



        $ ./configure --help



    to get a list.  Some of the more interesting flags are:




    --prefix:






        If you wish to install mysql++ in a root directory other than
        /usr/local, run configure with --prefix=/some/dir/name





    --with-mysql*:





        If you installed MySQL in an atypical location, the configure
        script will not be able to find the library and header
        files without help.  The simplest way to clue configure into
        where MySQL is installed is with the --with-mysql option.
        Try something like "--with-mysql=/usr/local/mysql", for
        instance.  The configure script will then try to guess which
        subdirectories under the given directory contain the library
        and include files.



        If that doesn't work, it's because the library and header
        files aren't in typical locations under the directory you gave
        for configure to find them.  So, you need to specify them
        separately with --with-mysql-include and --with-mysql-lib
        instead.  As with --with-mysql, configure can often guess
        which subdirectory under the given directory contains the
        needed files, so you don't necessarily have to give the full
        path to these files.



    
    --with-field-limit:



        This lets you increase the maximum field limit for template
        queries and SSQLSes.  By default, both are limited to 25
        fields.  See chapter 8.2 in the user manual for details:


        http://tangentsoft.net/mysql++/doc/html/userman/configuration.html


    --enable-thread-check:



        Builds MySQL++ with threading support, if possible.


        
        This option simply turns on two tests: first, that your
        system uses a compatible threading library; and second,
        that the thread-safe version of the MySQL C API library
        (libmysqlclient_r) is installed and working.  If both of
        these are true, you get a thread-aware version of MySQL++.
        "Thread-aware" means that the library does make an effort to
        prevent problems, but we don't guarantee that all possible
        uses of MySQL++ are thread-safe.

        Note that this is a suggestion, not a command.  If we can't
        figure out the system's threading model or can't find the
        thread-aware build of the C API library, configure won't fail.
        It just reverts to the standard single-thread build.


        See the chapter on threading in the user manual for more
        details and advice on creating thread-safe programs with
        MySQL++.







Building a Static Library
~~~~~~~~~~~~~~~~~~~~~~~~~
    As shipped, MySQL++ only builds a shared library.  It's possible to
    change things so you get a static library instead.


    Before we get to "how," beware that liking statically to MySQL++ has
    legal consequences that may matter to you, due to the library's
    license, the GNU LGPL.  Familiarize yourself with the license, and
    consider getting legal counsel before proceeding.  Also, see the
    MySQL++ FAQ: http://tangentsoft.net/mysql++/#faq  There is more on
    this topic there.

    The necessary changes are all in mysql++.bkl:



        - Change the <dll> tag to <lib>.  (Remember the closing tag!)

        - Remove the <dllname> tag




        - Remove the <so_version> tag


    Then, re-bootstrap the library.  See HACKERS.txt if you need further
    instruction on doing that.

MySQL++ was created by Kevin Atkinson during 1998.  From version

1.0 (released in June 1999) through 1.7.9 (May 2001), the primary
maintainer was Sinisa Milivojevic <sinisa@mysql.com>.  Neither Kevin
nor Sinisa are currently involved in MySQL++ development.  The current
maintainer is Warren Young <mysqlpp@etr-usa.com>, starting with
version 1.7.10 in August of 2004.


For a fuller account of the library's history, see the first chapter
of the user manual.  For the nitty-gritty details, see the ChangeLog
in the root package directory.  ChangeLog items since 1.7.9 that
aren't attributed to anyone else were done by Warren Young.



Other contributors of note since 1.7.10:



    Chris Frey <cdfrey@foursquare.net>: Lots of GCC warning fixes
    for the bleeding-edge compiler versions, Gentoo ebuild support,
    and misc other fixes.

    Mark Meredino <Mark_Merendino@cnt.com>: Several fixes and
    additions, including a lot of work on Microsoft Visual C++
    compatibility, and discoveries made while spelunking in the
    library.

    Evan Wies <evan@athenacr.com>: Contributed several C++ code
    style cleanups.



    Arnon Jalon <Arnon.Jalon@247RealMedia.com>: Added the multi-query
    result set handling features, and examples/multiquery.cpp to
    demonstrate it.


    Korolyov Ilya has submitted several patches in many different
    areas of the library.


    Remi Collet <Liste@FamilleCollet.com> is maintaining offical RPMs
    for Fedora, with other systems on the way.  His work has improved
    the RPM spec file we distribute greatly.


    Joel Fielder <joel.fielder@switchplane.com> of Switchplane,
    Ltd. created the ScopedConnection class, came up with the original
    idea for Query's for_each() and store_in() methods, provided the
    basis for examples/for_each.cpp, and provided a fix for exception
    flag propagation in Query.



    Jim Wallace <jwallace@kaneva.com> demonstrated the need
    for BadQuery::errnum(), and contributed the patches and also
    examples/deadlock.cpp to test that this feature does what it is
    supposed to.


    Jonathan Wakely <mysql@kayari.org> rebuilt my original versions
    of ConnectionPool, RefCountedPointer, and RefCountedBuffer.
    They're now simpler and safer.  He also created the numeric
    conversion logic in lib/mystring.h introduced in v3.0.









    Adrian Cornish <mysql@bluedreamer.com>  Several fixes and
    additions.









    Rick Gutleber <rgutleber@above.net> contributed the 
    Query::insertfrom() method and associated InsertPolicy object,
    as well as the SQLStream class.


Here are the personal credits from the old 1.7.9 documentation,
apparently written by Kevin Atkinson:




    Chris Halverson - For helping me get it to compile under Solaris.


    Fredric Fredricson - For a long talk about automatic conversions.


    Michael Widenius - MySQL developer who has been very supportive of
        my efforts.


    Paul J. Lucas - For the original idea of treating the query object
        like a stream.





    Scott Barron - For helping me with the shared libraries.








    Jools Enticknap - For giving me the Template Queries idea.




    M. S. Sriram - For a detailed dission of how the Template Queries
        should be implemented, the suggestion to throw exceptions on bad
        queries, and the idea of having a back-end independent query
        object (ie SQLQuery).

    Sinisa Milivojevic - For becoming the new offical maintainer.





    D. Hawkins and E. Loic for their autoconf + automake contribution.









See the ChangeLog for further credits, and details about the differences
between the many versions of this library.




Please do not email any of these people with general questions about
MySQL++. All of us who are still active in MySQL++ development read the
mailing list, so questions sent there do get to us:


    http://lists.mysql.com/plusplus



The mailing list is superior to private email because the answers are
archived for future questioners to find, and because you are likely to
get answers from more people.

Prerequisites
~~~~~~~~~~~~~
    You need to have the MySQL C API development files on your system,
    since MySQL++ is built on top of it.

    The easiest way to get it is to download Connector/C from
    mysql.com.




    If you need the MySQL server on your development system anyway,
    you you can choose to install the development files along with
    the server.  Some versions of the MySQL Server installer for
    Windows have installed the development files by default, while
    others have made it an optional install.









Project Files
~~~~~~~~~~~~~
    The distribution comes with three sets of .sln and .vcproj files
    in the vc2003, vc2005 and vc2008 subdirectories.




    We do this for several reasons:


      1. It lets you build MySQL++ with multiple versions of Visual
         C++ without the build products conflicting.


      2. For Visual C++ 2003, we had to disable the SSQLS feature
         because changes made in MySQL++ 3.0 now cause the compiler
         to crash while building.  See the Breakages chapter in the
         user manual for workarounds if you must still use VC++ 2003.



      3. The VC++ 2008 project files get built for 64-bit output, while
         the other two build 32-bit executables.


         With VC++ 2003, we have no choice about this, since it only
         supports 32-bit targets.


         VC++ 2005 did have experimental 64-bit compilers available,
         but their beta nature was only one reason we chose not to
         use them.  The real reason is that the current MySQL++ build
         system isn't currently set up to make it easy to build both
         32- and 64-bit libraries and executables at the same time
         within the same solution.  Bakefile allows it, but it would
         require forking many of the build rules in mysql++.bkl so
         we can do things like have separate MYSQL_WIN_DIR values
         for each bitness.  (See below for more on this variable.)


         For that same reason, the VC++ 2008 project files are set
         up to build 64-bit libraries and executables *only*.



    It is possible to upgrade these project files to work with newer
    versions of Visual C++, but beware that the upgrade feature tends
    to be problematic.


    If you want to do a 32-bit build on VC++ 2008 or newer, it is
    easiest to open the vc2005\* project files and let Visual Studio
    upgrade them for you.  The alternative, starting with the vc2008
    files, requires that you add a 32-bit build option to all of the
    many targets in MySQL++, then optionally delete the 64-bit targets.
    This is a lot more work.  Plus, it only works if you have the
    64-bit compilers installed, since Visual Studio will refuse to
    open project files where all targets must be built with compilers
    that aren't installed, even if your goal is to immediately adjust
    them to use compilers that *are* installed.


    When converting the VC++ 2008 project files to VC++ 2012, Visual
    Studio will change the output directories from Debug to Debug\x64
    (and similar for Release), but it won't also change the link paths
    from Debug to Debug\x64, so that the library and examples will
    compile but not link.  The migration tool detects that there is
    a problem, but it can't fix its own mess.  You have to manually
    fix it.


    There were also problems in VC++ 2010 when you had converted 32-bit
    VC++ 2008 projects and then were trying to switch them to 64-bit.
    It ended up being simpler in this case to just start over from
    scratch and build your own project files.




Using Nonstandard MySQL Installations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    The Visual Studio project files that come with MySQL++ have
    everything set up correctly for the common case.  The biggest
    assumption in the settings is that you're building against the
    current stable version of Connector/C, which gets installed here
    at the time of this writing:


        C:\Program Files\MySQL\MySQL Connector C 6.1\


    If you installed a different version, or it's in a different
    directory, or you've installed the development files as part of
    MySQL Server on the same machine, you need to change the project
    files to reference the C API development files in that other
    location.  There are two ways to do this.


    The hard way is to make 16 different changes each to 44 separate
    project files.  If you're a talented Visual Studio driver,
    you can do this in as little as about 5 or 6 steps.  You might
    even get it right the first time.  If you are not so talented,
    you have to make all ~700 changes one at a time, and you almost
    certainly will *not* get it right the first time.

    The somewhat easier way is to open all these files in a text
    editor that lets you make a global search and replace on all
    open files.

    The easy way is to install Bakefile (http://bakefile.org/),
    change the value of the MYSQL_WIN_DIR variable near the top of
    mysql++.bkl in the top level of the MySQL++ source tree, and run
    rebake.bat.  This will rebuild all of the project files for you,
    using the new MySQL path in all the many places it's needed.


Building the Library and Example Programs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    You must build both the Debug and Release versions of the library,
    because a release build of your program won't work with a Debug
    version of the MySQL++ DLL.  These DLLs get different names, so
    you can install them in the same directory if needed: mysqlpp_d.dll
    for the Debug version, and mysqlpp.dll for the Release version.

    With the library built, run at least the resetdb and simple1
    examples to ensure that the library is working correctly.
    In addition to the other generic examples, there are a few
    Visual C++ specific examples that you might want to look at in
    examples\vstudio.  See README-examples.txt for further details.

    Once you're sure the library is working correctly, you can run
    the install.hta file at the project root to install the library
    files and headers in a directory of your choosing.
    
    (Aside: You may not have come across the .hta extension before.
    It's for a rarely-used feature of Microsoft's Internet Explorer,
    called HTML Applications.  Know what Adobe AIR is?  Kinda like
    that, only without the compilation into a single binary blob which
    you must install before you can run it.  Just open install.hta
    in a text editor to see how it works.)


Using MySQL++ in Your Own Projects
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    This is covered in the user manual, chapter 9.


Working With Bakefile
~~~~~~~~~~~~~~~~~~~~~
    MySQL++'s top-level Visual Studio project files aren't
    maintained directly.  Instead, we use a tool called Bakefile
    (http://bakefile.org/) to generate them from mysql++.bkl. Since
    there are so many project files in MySQL++, it's often simpler to
    edit this source file and "re-bake" the project files from it than
    to make your changes in Visual Studio.

    To do this, download the native Windows version of Bakefile from the
    web site given above.  Install it, and then put the installation
    directory in your Windows PATH.  Then, open up a command window, cd
    into the MySQL++ directory, and type "rebake".  This will run
    rebake.bat, which rebuilds the Visual Studio project files from
    mysql++.bkl.

    There's more information about using Bakefile in HACKERS.txt.


If You Run Into Problems...
~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Especially if you have linking problems, make sure your project
    settings match the above.  Visual C++ is very picky about things
    like run time library settings.  When in doubt, try running one
    of the example programs.  If it works, the problem is likely in
    your project settings, not in MySQL++.

Building the Examples
~~~~~~~~~~~~~~~~~~~~~
    If you're installing MySQL++ from the source tarball, the example
    programs get built when you build the library.  If you change
    any example code, just say 'make' to rebuild the examples.
    The examples are built against the headers and library in the
    lib subdirectory, not against the ones you may have installed
    elsewhere on the system.

    If these example files were installed on your system as part of
    the -devel RPM, copy all the files to a directory you can write
    to, then say 'make' in that directory.  This uses a simplified
    Makefile, which builds the examples against the headers and
    libraries installed in the system directories.


Getting Started with the Examples
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    MySQL++ is built as a shared library on most systems, and a DLL
    on Windows.  Since it isn't built in the same directory as the
    examples, this means that your system won't be able to find the
    library without help until you install it.  Since you generally
    want to run the examples _before_ installing the library, to test
    that the library actually works, we need a workaround.

    That workaround is the exrun script.  There are two versions,
    a Bourne shell script called just exrun for POSIX systems, and
    exrun.bat for Windows.

    Before running the other examples, you must first create the
    sample database.  On POSIX systems, you do that like so:

        $ ./exrun resetdb [-s server_addr] [-u user] [-p password]

    On Windows, that would instead be:

        C:\mysql++\> exrun.bat resetdb [-s server] [-u user] [-p pass]

    You don't have to give any of these options.  If you don't pass -s,
    it assumes the database server is running on the same machine,
    and so tries to contact the server over some form of local IPC.
    If you don't pass -u, it uses your own user name when logging
    into to the database server.  If you don't pass -p, it assumes the
    database user has an empty password, which hopefully is not true.

    The -s option accepts many different forms of address.  The main
    one is some sort of TCP/IP address, with an optional port number
    or service name.  On Unixy systems, you can give a Unix domain
    socket name.  On Windows, you can give just a period to use named
    pipes, if the server supports it.  All of these are legal:

        .
        localhost
        172.20.0.252:12345
        /var/run/mysqld.sock
        my.server.name.com:mysql

    If you give -s but don't give a port number or service name with
    it, it assumes the default, port 3306.


Running the Other Command Line Examples
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    The following examples use the database set up by resetdb, and
    have the same command line format as resetdb:

        simple1: Shows the item names for all records in the sample
            stock table.  Try this one if you do nothing else.

        simple2: Similar to simple1, but it displays all columns
            from the sample stock table, not just the item name.

        simple3: Same as simple2, except that it retrieves the data
            with a "use" query instead of a "store" query.  See the
            user manual for the difference between these methods.

        ssqls1-5: These demonstrate the SSQLS features.  Read the
            SSQLS sections in the user manual for details about
            these examples.

        multiquery: MySQL++ allows you to issue multiple queries at
            once, and get the results as separate sets.  This shows
            that, and also how to use stored procedures, which return
            their results in the same way as a multiquery.

        tquery1-3: Shows how to use the template query facility.

        transaction: Shows how to use the Transaction class to create
            transaction sets which automatically roll back if not
            explicitly committed.

        deadlock: Shows how to handle errors that happen when the
            database server detects a deadlock in a transaction set.
            Also demonstrates the need for BadQuery::errnum()

        store_if: Demonstrates the Query::store_if() method, which
            allows you to store the results of a query in an STL
            container conditionally.  Think of it as a way to express
            rules for selecting records in C++, to be used when SQL's
            WHERE clause isn't powerful enough.

        for_each: Demonstrates the Query::for_each() method, which
            allows you to execute a query and call a functor on each
            returned row.  This example uses this to gather statistics
            on the sample table's contents.

        cpoolp, cpoolw: Respectively, the POSIX and Windows threads
            variants of the ConnectionPool class demonstration.

        load_jpeg: Inserts a JPEG file into the sample database,
            for use by the cgi_jpeg example.  (See below.)  Unlike the
            other examples, this one takes anything given on the
            command line that isn't a switch to be a JPEG file name.
            We've included examples/logo.jpg as a sample, if you want
            to use that.

        fieldinf: Shows how to get information about the fields in
            a result set.  (Types, etc.)

        dbinfo: Dumps a bunch of information about the database
            server and some of the data it's managing.

    If you run the load_jpeg example, you should consider also
    playing with the other half of the demonstration, cgi_jpeg.
    To run it, you'll need to install MySQL++ on a machine with
    a web server, then copy the cgi_jpeg program to the server's
    CGI directory.  For example, on a stock Red Hat type box,
    that would be /var/www/cgi-bin.  At that point, a request like
    http://my.server.com/cgi-bin/cgi_jpeg?id=1 should show the JPEG you
    loaded.  The ID value to use will be that reported by load_jpeg.


Dedicated Windows Examples
~~~~~~~~~~~~~~~~~~~~~~~~~~
    If you're a Visual C++ user, there are two GUI examples, too:

        examples\vstudio\mfc.vcproj: MFC-based replacement for
            the simple2 example.

        examples\vstudio\wforms.vcproj: The same thing, only written in
            C++/CLI and using Windows Forms.  Please follow the
            instructions in README-Visual-C++.txt before trying to
            build and run this example.  The MySQL++ library build
            settings must be modified and the library rebuilt first.

    Although these examples show use of MySQL++ in a GUI rather than
    command line program, that's not the main point of these examples.
    What we're really showing here is how to deal with Unicode.
    The MySQL server prefers the UTF-8 encoding for Unicode, which
    works naturally with most non-Windows systems.  Windows, on the
    other hand, uses a different Unicode character encoding, UCS-2.
    These examples show how to do the necessary conversions.  (See the
    Unicode chapter in the user manual for more on this topic.)

    We need two different examples because Unicode conversions and
    string handling are so wildly different under .NET than with the
    native Win32 API.  .NET makes these tasks much easier.

    These examples build and run as-is under Visual C++ 2005.  To make
    them work with VC++ 2008, you will have to change several paths
    in both project's settings to reference the "vc2008" subdirectory
    instead of "vc2005":

        o Configuration Properties > Debugging > Working Directory

        o Configuration Properties > Linker > General >
          Additional Library Directories

    If you want to backport these examples to VC++ 2003, it's probably
    not hard.  The main difficulty is that VS 2003 supports Managed
    C++, which isn't the same thing as C++/CLI.


Special exrun Capabilities
~~~~~~~~~~~~~~~~~~~~~~~~~~
    The Bourne shell version of the exrun script has a few features
    not avaiable in the Windows batch file version.  These features
    let you run the examples under various debugging tools.

    You can get simple gdb debugging if you run an example like this:

        $ ./exrun gdb simple1 foo bar qux

    The script also supports valgrind, in memory leak testing mode:

        $ ./exrun valgrind simple1 foo bar qux

3.0.6, 2008.08.16 (r2350)

    o Several fixes to allow thread-aware build on Solaris

    o More improvements to search for Fink version of C API library.

    o Various improvements to Windows installer (install.hta)


3.0.5, 2008.08.06 (r2332)

    o Replaced install.bat with new install.hta, which has a GUI and a
      lot of embeded logic for doing The Right Thing, which we couldn't
      do in a dumb batch file.

    o Several fixes to allow it to build on Solaris 10.

    o Fixed a bug in comparison of Null<T> to T: wouldn't always give
      the right result for one particular combination of argument
      values and order of parameters to operator <().  It wouldn't
      fail all the time, either; it depended on the way the system's
      memory allocator dealt with newly allocated RAM.  The bug was
      discovered during the Solaris 10 porting effort, but it is not
      a Solaris-specific bug.

    o Split Linux-specific material out of README-Unix.txt into
      README-Linux.txt, and created README-Solaris.txt.

    o Shipping a vc2008 directory.  Populated by bootstrap script with
      copies of vc2005 files when those are newer, with the idea being
      to update them by hand by running them through VC++2008 before
      release.

    o Several fixes to VS-only examples. They hadn't been updated to
      track several of the changes in MySQL++ v3, so they wouldn't
      build OOTB at all, crashed when you did get them building, and
      emitted a lot of warnings during the build.  Cleaned it all up.

    o Autoconf now explicitly checks whether we need to link to zlib
      to link to MySQL C API library.  It used to be required, but
      lately, MySQL has been shipping the library with zlib stuff
      embedded, causing multiply defined symbol errors on some systems.

    o configure script now looks in more locations for the MySQL C API
      library, adding default locations for Fink and Solaris.


3.0.4, 2008.07.02 (r2303)

    o Fixed a few bugs in SslOption that prevented it from actually
      working.  If you've been having SSL problems since upgrading
      to MySQL++ v3, this is why!  Thanks for these patches go to
      Petteri Kiiskinen.

    o Changed type of String's internal "size" typedefs so it'll
      build without errors on 64-bit systems where these ints are
      different sizes.

    o Many user manual improvements.


3.0.3, 2008.05.11 (r2284)

    o Fixed query well-formedness handling in Query::store() and use().
      It was quietly eating these errors, confusing them with the
      no-results case.

    o Fixed examples/cpool.cpp to build without thread support.

    o No longer hiding all stdint.h typedefs inside namespace mysqlpp.

    o Fixed mysqlpp::String comparisons of empty strings against
      nonempty strings; if the empty string was on the left hand side,
      it would succeed because it was only comparing against characters
      in the empty side, which matches everything.  (Fixes bug 11588.)


3.0.2, 2008.04.13 (r2275)

    o Increased float to string conversion precision from 7 to 9 and
      double from 16 to 17 digits.  Previous values weren't enough
      near the maximum values that each can hold.

    o Replaced Query's safe bool mechanism with an override of
      basic_ios::operator void*() to avoid a conflict between the
      two mechanisms.  As the base class version isn't virtual,
      this is arguably evil, but it should be harmless in typical use.
      Besides, testing Query in bool context usually isn't the right
      thing anyway: test the result set instead.

    o Made ConnectionPool::grab() virtual.

    o Overriding ConnectionPool::grab() and release() in
      examples/cpool.cpp to show how to do connection-in-use count
      limiting.  Also, added a few more output indicator states to
      allow one to better understand program flow.


3.0.1, 2008.03.23 (r2263)

    o String objects can now be compared to mysqlpp::null directly.

    o Added a template operator== and operator!= to String, syntactic
      sugar for the existing String::compare() methods.

    o String::compare() now returns 0 ("equal") when one of the
      strings is an uninitialized String() (no refcounted buffer)
      and the other is empty.  It used to consider any initialized
      string greater than an uninitted one.  An uninitialized String
      appears empty, though, so this was incorrect.

    o Made Connection::thread_aware(), thread_start() and thread_end()
      static methods, so they can be called before you create your
      first connection.  Ditto for DBDriver versions of these methods.

    o Calling Connection::thread_start() and thread_end() in
      examples/cpool.cpp, as appropriate.  Above changes were necessary
      to make this work sensibly.

    o Made ConnectionPool::release() virtual, so your pool subclass can
      override it.

    o Added ConnectionPool::size(), so a subclass can know the current
      number of extant connections.

    o No longer single-quoting NOW() call generated for default
      init of DateTime type when building queries from SSQLS objects
      in Query::insert(), replace() and update().  The template query
      and stream interfaces of Query treated NOW() correctly already.

    o Fixed a bug that left SSQLS::table_override_ uninitted if
      you used certain of the generated ctors or set() member
      functions instead of others used by the examples.  This could
      cause a crash any time you caused SSQLS.table() to be called,
      such as when passing the SSQLS to Query::insert().

    o Minor memset bug fixed in test/uds.cpp.  Patch by Dave Jones.


3.0.0, 2008.02.29 (r2236) The "Giant Leap Forward" release

    THIS IS NOT A DROP-IN REPLACEMENT FOR MySQL++ v2.x!

    You will have to recompile your program against this version
    of the library, and you will almost certainly have to make code
    changes as well.  Please see these sections in the user manual
    for information on migrating your code to this new version:

    http://tangentsoft.net/mysql++/doc/html/userman/breakages.html#api-3.0.0
    http://tangentsoft.net/mysql++/doc/html/userman/breakages.html#abi-3.0.0

    o Added ConnectionPool class, primarily to let multithreaded
      programs share a set of Connection objects safely in situations
      where it isn't acceptable to have a Connection per thread.

    o Created examples/cpool.cpp to demonstrate this new class.

    o Added RefCountedPointer template, which provides automatic
      memory management and data sharing.  It's not intended
      for use outside of MySQL++ itself, but it's the mechanism
      behind everything below where reference counting is mentioned.
      I created the initial version of it, but Jonathan Wakely almost
      completely rebuilt it, and Joseph Artsimovich provided helpful
      commentary and advice as well.

    o Many improvements to Specialized SQL Structures (SSQLS):

      - Renamed custom* to ssqls*.  There's still a custom.h which
        #includes ssqls.h for you, but it's only intended to ease
        the transition to the new name.  It will go away in a future
        release, probably as soon as v3.1.

      - SSQLSes are finally compatible with Null<>-wrapped types.  This
        feature is based loosely on the "Waba" patch posted to the
        mailing list back in the v2.0 days, but extended to allow
        Null<T> types for key fields.  (The Waba patch only allowed
        these types in non-key fields.)

      - It's no longer necessary to define a different SSQLS for each
        different field set you use in queries.  That is to say,
        you can define an SSQLS for an entire table and store just a
        subset of the table in it now, with the other fields keeping
        default values.  Removed examples/custom6.cpp, as custom1.cpp
        can now demonstrate the same thing, implicitly.

      - An SSQLS's field order no longer has to match the order of
        fields in the result set it is populated from.

      - As a result of previous, removed sql_create_c_order_* macros;
        they have no purpose now.

      - Removed order parameters from sql_create_complete_*, which now
        gives it the same functionality as sql_create_c_names_* so
        removed the latter, too.

      - Removed "basic" variants of SSQLS creation macros.  They've
        been unofficially deprecated by dint of being all but
        undocumented and unexemplified for a very long time now.

      - It's now possible to use mysqlpp::String, Date, DateTime, and
        Time types in the key field positions in an SSQLS as they
        now support the necessary comparison interfaces.

      - If you use a floating-point data type in one of the key field
        positions, it no longer uses exact comparison logic.  Instead,
        it now does [in]equality comparisons by testing whether the
        difference between two floating-point values is less than a
        configurable threshold defaulting to 0.00001.
    
      - You can now use 'bool' type in an SSQLS.

      - Renamed _table static member variable in each SSQLS to table_
        and made it private.  There are now public setter and getter
        methods, table().

      - Added per-instance table name overriding via instance_table()
        setter.  table() getter returns static version if this is not
        set, so it's still a global setting by default.

    o You can now use mysqlpp::null as a template query parameter to
      get a SQL null.

    o Replaced template ColData_Tmpl<T>:

      - Used to have typedef ColData_Tmpl<std::string> MutableColData.
        It was used only once within MySQL++ itself, and was never
        documented as a class for end users.  This one use within
        the library was a crock, so we just replaced this use with
        std::string and removed the typedef.

      - This left just one use of ColData_Tmpl<T>, instantiating it
        with the MySQL++ utility class const_string, basically a
        clone of std::string with all the mutating features removed.
        Folded the functionality of const_string into the template,
        renamed the result to String, and deleted the const_string
        class.  It'd be a complete std::string replacement -- with
        SQL-related enhancements -- if it were modifiable, but MySQL++
        doesn't need it to be modifiable.  Yet, it's still the closest
        thing MySQL++ has to its own string type; thus the name.

      - Replaced its internal buffer management with a much more
        clever reference counted scheme.  This shows its greatest
        advantage in the return from Row::operator[](), which for
        technical reasons must return by value, not by reference
        as is more common.  This lets you pass around Strings by
        value while having the efficiency of reference semantics.
        This can be important with large return values, like BLOBs.

      - Converting String to numeric types (ints, floats...) uses a
        new, cleaner system by Jonathan Wakely.  Unless you were
        abusing weaknesses in the old system, you won't see a
        difference.  It's just more robust and flexible.

    o Redesigned SQLString:

      - It used to derive from std::string, and while MySQL++'s
        internals did use it in place of std::string, these places
        didn't take advantage of the additional features offered
        by SQLString.  So, replaced all those uses with std::string.

      - All the remaining uses are MySQL++ public interfaces that
        need to be able to accept any of many different data types,
        and we want that data to be automatically converted to a
        SQL-compatible string form.  Because it no longer has the
        parentage to be a general-purpose string type and MySQL++ has
        a new contender for that role (String), renamed SQLString to
        SQLTypeAdapter to reflect its new, limited purpose.  ("STA"
        for short.)

      - Since we don't have the std::string base class to manage the
        string buffer any more, using the same reference counted
        buffer mechanism as String.  In addition to saving code by
        not creating yet another buffer management mechanism, it means
        objects of the two classes can share a buffer when you assign
        one to the other or pass one to the other's copy ctor.

      - Added many more conversion ctors.

      - STA interfaces using the 'char' data type now treat them as
        single-character strings instead of one-byte integers, as
        does the Standard C++ Library.

      - Added mysqlpp::tiny_int interfaces to STA to replace the
        former char interfaces for those needing one-byte integers.

    o As a result of the ColData -> String redesign, removed
      Row::raw_*().  Before String copies were efficient, this
      was helpful in accessing BLOB data efficiently.  It was also
      required back when ColData didn't deal correctly with embedded
      null characters, but that reason is gone now, too.

    o Row::operator[](const char*) no longer unconditionally throws the
      BadFieldName exception when you ask for a field that doesn't
      exist.  It will still throw it if exceptions are enabled, but if
      not, it'll just return an empty String.  This was necessary to
      make the SSQLS subset and field order independence features work.

    o Similarly, Result::field_num() returns -1 when exceptions are
      disabled and you ask for a field that doesn't exist.

    o You can now use the OptionalExceptions mechanism to disable
      exceptions on const MySQL++ objects.

    o Redesigned query result classes:

      - Instead of Result deriving from ResUse, the two derive from
        a common base class -- ResultBase -- containing the bits that
        are truly the same between them.  Before, Result inherited
        several methods that didn't really make sense for "store"
        query result sets.

      - Renamed Result to StoreQueryResult and ResUse to UseQueryResult
        so it's clearer what each is for.

      - Renamed ResNSel to SimpleResult.

      - Made all SimpleResult data members private and hid them behind
        const accessor functions of the same name.

      - The result set classes all used to be friends of Connection
        for various lame reasons.  Since they are created by Query,
        and Query has a good reason for a strong relationship with
        Connection, moved Connection access out of each result set
        class into the code in Query that creates that type of result
        set object.

      - StoreQueryResult now derives from vector<Row> in addition to
        ResultBase; it used to merely emulate a vector of Rows, poorly.
        It can now dispose of the MYSQL_RESULT at the end of object
        construction, because it creates all the Row objects up front
        instead of on the fly.  And as a result of *that*, operator[]
        returns by reference instead of by value, operator -> works
        correctly on iterators, all STL algorithms work, etc., etc.

      - IMPORTANT COMPATIBILITY BREAK: because we used fetch_row()
        stuff in Result previously, it was okay to index past the
        end of the result set: you'd just get a falsy Row when you
        did this, just as happens when doing the same thing in a
        "use" query.  The simple1 and simple2 examples did this,
        so it's likely that code exists that takes advantage of this
        misfeature.  New versions of these examples show how to index
        through a StoreQueryResult without running past its end.

      - ResUse used to delay creation of its FieldNames and FieldTypes
        objects until the point of need.  This had several implications
        for thread and exception safety that we fix by just creating
        them in the ctor.  If your code is multi-threaded and was
        avoiding certain usage patterns due to crashes, it's worth
        trying your preferred way again.

      - Result sets create a few data structures to hold information
        common to all rows in that set.  The row objects need access
        to these shared data structures, so on creation each gets
        a pointer back to the result set object that creates it.
        This was efficient, but required that a result set object
        outlive any row objects it creates.  Now these shared data
        structures are reference-counted, decoupling the lifetime of
        the child row objects from their result set parent.

      - Copy operations for result sets used to actually be "moves"
        before, for efficiency.  (MySQL++ itelf only copied result
        sets in returning them by value from the query execution
        methods of Query, so this was acceptable if you didn't do
        anything uncommon with these objects.)  Reference counted
        data structures allow us to have copy semantics now without
        sacrificing efficiency.

      - You can now use Query::storein() with an STL container of Row
        objects now, instead of having to use SSQLSes.  The lifetime
        issue guaranteed a crash if you tried this before.

      - Removed a bunch of unnecessary alias methods:

        - columns() -> num_fields()
        - names()   -> field_names()
        - rows()    -> num_rows()
        - types()   -> field_types()

      - Renamed several methods for grammar reasons:

        - fields(unsigned int)      -> field(unsigned int)
        - names(const std::string&) -> field_num(const std::string&)
        - names(int)                -> field_name(int)
        - types(int)                -> field_type(int)

      - Removed several "smelly" methods:

        - purge()
        - raw_result()
        - reset_names()
        - reset_field_names()
        - reset_types()
        - reset_field_types()

    o Field class used to just be a typedef for the corresponding C
      API class.  Now it's a real C++ class providing a more MySQL++
      sort of interface, plus good OO things like information hiding
      and implementation detail abstraction.  This changes several
      things about the interface.

    o Fields class was basically a specialized std::vector work-alike
      for dealing with the C API to get access to MYSQL_FIELD objects
      and present them as contained Field objects.  New Field type
      let us replace it with "typedef std::vector<Field> Fields"

    o Major improvements to the quoting and escaping mechanisms:

      - Replaced almost all of the type-specific interfaces in manip.h
        with a single version taking STA.  The compiler can convert
        almost anything to STA without losing any information we need
        for correct quoting and escaping.  This has the side benefit
        that we can now do correct quoting and escaping for more data
        types now, including plain C and C++ string types.

      - Fixed a bug in quote_double_only manipulator for String: was
        using single quotes by mistake.

      - Escaping and quoting only works in instances where MySQL++
        can tell you're building a SQL query and are using a data type
        that requires it.  This affects many things, but the one most
        likely to cause trouble is that inserting MySQL++'s quoting
        and escaping manipulators in non-Query ostreams is now a no-op.

      - Added escape_string() member functions to Query and
        SQLQueryParms::escape_string(), and removed the global function
        of the same name.  Because these are tied indirectly to a
        Connection object, this also has the effect that escaping is
        now aware of the current default character set used by the
        database server.  There's only one case where this isn't done
        now, and that's when we're disconnected from the server.

      - Previous two items form a trade-off: if your code was depending
        on MySQL++ to get SQL escaping and it no longer happens for
        what we consider a good reason, you can build a replacement
        mechanism using these new functions.  Quoting needs no special
        support in MySQL++.

      - Removed 'r' and 'R' template query parameter modifiers,
        which meant "always quote" and "always quote and escape"
        regardless of the data type of the parameter.  There are no
        corresponding manipulators (for good reason), so the removal
        restores symmetry.

    o Created DBDriver class from code previously in Connection and
      Query to almost completely wrap the low-level MySQL C API:

      - Connection creates a DBDriver object upon connection and
        passes a pointer to it down to Query objects it creates.
        In turn, they pass the pointer on to any of their children
        that need access to the C API.

      - Nothing outside DBDriver calls the C API directly now, though
        DBDriver leaks C API data structures quite a lot, so this
        feature doesn't constitute "database independence."  See the
        Wishlist for what must be done to get to that point.

    o Completely redesigned the connection option setting mechanism:

      - There's now just a single Connection::set_option() method that
        takes a pointer to the abstract Option base class, and there is
        an Option subclass for every connection option we understand.
        Thus, type errors are now caught at compile time instead of
        at run time.

      - Replaced Connection::enable_ssl() with SslOption class.

      - Enabling data compression and setting the connection timeout
        are no longer set via parameters to Connection interfaces.
        These are now set with CompressOption and ConnectTimeoutOption.

      - Similarly, removed client_flag parameters from Connection's
        ctor and connect() method and added corresponding Option
        subclasses.  There's about a dozen, so rather than list them
        here, look for similarly-named classes in lib/options.h.

    o Added Connection::count_rows() to execute "SELECT COUNT(*) FROM
      tablename" queries for you.

    o Moved Connection::affected_rows(), info() and insert_id() methods
      to class Query, as they relate to the most recently-executed
      query, not to the connection.

    o Several method name changes in Connection:

      - client_info()   -> client_version()
      - host_info()     -> ipc_info()
      - proto_info()    -> protocol_version()
      - server_info()   -> server_version()
      - stat()          -> status()

    o Removed Connection::api_version().  It does the same thing as
      client_version().

    o Lots of changes to Date, DateTime, and Time classes:

      - If you use the default constructor for DateTime and don't
        subsequently set its year, month, day, hour, minute or second
        data members to nonzero values, it becomes the SQL function
        "NOW()" in a query string.  You can also use DateTime::now()
        as syntactic sugar for this.

      - As a result of above, had to hide all of DateTime's data
        members behind accessor functions, to keep the state of the
        object consistent.  (If it's initialized as "now" and you
        give it an explicit year value, say, it is no longer "now",
        so the setter has to clear the now-flag.)  There are getters
        and setters for year, month, day, hour, minute and second,
        all named after the member.

      - Did the same for Date and Time for consistency, even though it
        isn't technically required.

      - The sql_timestamp typedef now aliases DateTime instead of Time.

      - Renamed template class DTbase<T> to Comparable<T>.  The fact
        that it's the common base class of all date and time classes
        is irrelevant; making subclasses comparable is what it does,
        so that's what it should be named after.

      - Added a DateTime ctor taking discrete year, month, day, hour,
        minute, and second values.

      - Implicit conversion from stringish types to the date and time
        types is no longer allowed.  This is part of the "Waba"
        Null<T> patch mentioned above; allowing implicit conversions
        would break this new feature.

      - Added operator std::string and str() methods to all of these
        classes.  Adding this to the existing operator << support, you
        now have several ways to convert these objects to string form.

      - Added time_t conversion to Date and Time classes.  DateTime
        already had it, since it's more legitimate to convert time_t
        to DateTime, but you could already "slice" it with something
        like Time(DateTime(time(0))) so there's no point pretending
        you can't get from time_t to Date or Time.  Might as well
        legitimize it.

    o Improved tiny_int class:
        
      - Turned it into a template parameterized on the value type so
        you can get both signed and unsigned TINYINTs

      - Changed the sql_tinyint and sql_tinyint_unsigned typedefs to
        use mysqlpp::tiny_int<VT> instead of raw chars

      - Added a bool conversion ctor and operator, and typedef'd it
        to sql_bool and sql_boolean to match MySQL server behavior

    o Added many more sql_* typedefs.  We now have a typedef for every
      type the MySQL server knows about, including those it supports
      just for compatibility with other database servers.

    o Changed the sql_*int* typedefs to use integer types of the same
      size as the MySQL server.  (Run test/inttypes.cpp to test it.)

    o Added copy ctor and assignment operator to Row.

    o Row::operator[]() takes int now instead of unsigned int.
      This finally (!) makes it possible to say row[0] without the
      compiler giving an ambiguous overload error.

    o Changed all uses of row.at(0) in the examples to row[0]

    o Added operator[] to all classes that only had at().

    o Query now automatically resets itself unless the query fails
      or you're using template queries.  In either case, the contents
      of the query's internal buffers are considered precious,
      either for debugging, or future queries.  Except when using
      template queries, this means you may be able to avoid calling
      Query::reset() entirely.  It's still safe to call reset()
      as before, just unnecessary most of the time.

    o Removed reset_query parameter from all Query methods.  It was
      almost completely broken before, and above change does what
      was really wanted to begin with.

    o Query::store_next() and Result::fetch_row() no longer throw
      the EndOfResults and EndOfResultSets exceptions; these are not
      exceptional conditions!  These methods simply return false now.

    o Removed examples/usequery.cpp: there's no essential difference
      between what it did and what examples/simple3.cpp does now as
      a result of the previous change.

    o Added Query::exec(void), paralleling Query::execute(void).

    o Removed Query::preview().  The most direct replacement is str(),
      which has always done the same thing.

    o You can now insert a Query object into an ostream to get a copy
      of the built query.  This means Query::str() is only necessary
      when using template queries.

    o Removed overloads of Query::execute(), store(), and use()
      that take const char*.  It was redundant because const char*
      converts implicitly to STA, for which overloads already exist.

    o Renamed Query::def to Query::template_defaults to make its
      purpose clearer.

    o Query::error() now returns const char*, not a std::string by
      value.  There's no point in making a copy of the error string.
      The method is now const as well, as it doesn't change the
      Query object.

    o Added Query::errnum(), which just wraps Connection::errnum().

    o Added error number parameters and accessor functions to BadQuery,
      ConnectionFailed and DBSelectionFailed exceptions, to preserve
      the state of Connection::errnum() at the point of the exception,
      so you don't have to rely on this value remaining unchanged
      during the exception throw process.  All places that use these
      exceptions now include this value where possible.  Thanks for the
      initial patch go to Jim Wallace.

    o Removed Lockable mechanism from Connection and Query; it was
      conceptually flawed.  See the new user manual chapter on
      threading for advice on using MySQL++ safely without locking.
      There is mutex locking now in ConnectionPool, but that's it.

    o Connection::query() now takes an optional query string, allowing
      the returned Query object to start off with a value.  Especially
      useful when the query string is static, either because it's
      a simple query or because it's a template.  You can now build
      chains like "if (conn.query("CREATE INDEX ...").exec()) { ..."

    o Added Connection::thread_aware(), thread_end(), thread_id()
      and thread_safe().  See user manual's threading chapter for
      explanations.

    o Renamed "success" data members in Connection, Query and
      SimpleResult (neé ResNSel) to "copacetic_", making them private
      if they weren't before.  This better reflects their actual
      use, which isn't to say that there has necessarily been actual
      success, but rather that everything's okay with the object.

    o Removed success() member functions from above classes.  All can
      be tested in bool context to get the same information.

    o Replaced all operator bool()s in MySQL++ classes with safer
      alternatives.  See http://www.artima.com/cppsource/safebool.html
      Thanks to Jonathan Wakely for much helpful commentary, advice,
      and code used in these mechanisms.

    o Decoupled Connection::copacetic_ from Connection::is_connected_.
      It is now possible for the object to be copacetic without being
      connected.  However, if it tries to connect and fails, then
      it is not copacetic.  If it is copacetic and not connected, it
      means we haven't even tried to connect yet, a useful distinction.

    o Collapsed Connection's host, port, and socket_name down into
      a new combined 'server' parameter which is parsed to determine
      what kind of connection you mean.  These interfaces are still
      compatible with v2.3 and earlier up through the port parameter.
      There are differences beyond this.

    o Added TCPConnection, UnixDomainSocketConnection and
      WindowsNamedPipeConnection subclasses for Connection giving
      simpler construction and connect() method interfaces for
      instances where you know what kind of connection you want at
      compile time.

    o Changed Connection::ping() return value from int to bool.

    o Renamed NullisNull to NullIsNull -- capital I -- and similar for
      NullisZero and NullisBlank.

    o It's now a compile-time error to try to convert a MySQL++
      representation of a SQL null to any other data type, rather
      than a run-time error as in previous versions.  Removed
      BadNullConversion exception as a result.

    o Way back in v1.7.x we used the BadQuery exception for all kinds
      of exceptional conditions, not just bad queries.  Replaced
      most of these in v2.0.0 with new dedicated exceptions, but a
      few remained:
      
      - Errors that occur during the processing of a "use" query after
        the query itself executes correctly now throw UseQueryError.
        It's not a "bad query", because the query executed
        successfully.  It just choked during subsequent processing,
        so it's a different exception.  Thanks for this patch go to
        Jim Wallace.

      - Replaced BadQuery exceptions thrown in Row constructor due
        to bad ctor parameters with new ObjectNotInitialized exception
        This is also Jim Wallace's work.

    o The examples now all use getopt() type command line options
      instead of positional options.  This makes it possible to
      pass options in any order, leave at their default options that
      used to be in the middle of the sequence, and offer different
      subsets of options for different programs.  Also allows for
      special internal-use options, like -D passed by dtest to let
      examples change their behavior when run under dtest to produce
      only predictable output.

    o Split old libutil functionality into two modules, one holding
      all the "print data" functions, and another holding all the
      command line parsing stuff.  This makes it easier for newbies
      to ignore the command line stuff, treating it like a black box.
      The wish to understand the "print data" routines is much more
      common, so the two needed to be disentangled.

    o Renamed examples' libutil to libexcommon.

    o Removed connect_to_db() libutil function.  It combined command
      line parsing, which users don't care about, with database
      connection establishment, which they do care about.  Now the
      examples just call out to libexcommon to parse the command
      line, and use the values they get back to explicitly make the
      connection, so it isn't hidden.

    o Removed cchar and uint typedefs.

    o Redesigned dbinfo example's output to be easier to read.

    o Fixed an output formatting bug created in 2.3.0 that caused the
      tabular output from examples to not line up.

    o Renamed examples/tquery.cpp to tquery1.cpp.  Created tquery2.cpp
      to demonstrate passing parameters via a SQLQueryParametrs object
      instead of discretely.  Created tquery3.cpp for testing unquoted
      template parameters, such as integers.

    o Renamed fieldinf1.cpp example to fieldinf.cpp, and simplified
      its output so it can be part of the dtest sequence.

    o Renamed examples/xaction.cpp to transaction.cpp.  It created too
      much cognotive dissonance whenever thinking about both it and
      lib/transaction.cpp.

    o Added examples/deadlock.cpp, to test handling of exceptions due
      to server-side transaction deadlock detection.  Also added
      code to resetdb to create a table needed to test this.
      Initial version created by Jim Wallace to test the value of
      all his BadQuery exception work, with reworking by me.

    o Greatly expanded dtest suite.  Primary change is that we now
      have a handful of unit tests, where in v2.3.2 we only tested
      a subset of the examples.  Still very low coverage ratio,
      but it's a big improvement.

    o Optimized #includes, especially in lib/*.h to reduce
      dependencies and thus compile time when one of these changes.

    o Fixed a typo in RPM filename generation that prevented -devel
      RPM from recognizing that the corresponding MySQL++ library
      RPM was installed.

    o RPM spec file improvements by Remi Collet.

    o Renamed NO_LONG_LONGS to MYSQLPP_NO_LONG_LONGS to avoid a risk
      of collision in the global macro namespace.
    
    o First cut at Xcode2 project support.  Testing needed!

    o Debug build of library on VC++ and Xcode have a _d suffix now
      so you can have both versions of the library installed without
      conflict.

    o Moved the VC++ 2003 project files into a new vs2003 subdirectory
      because there are so many of them.  Also created vs2005
      subdirectory for VC++ 2005 and 2008 compatible project files.
      2005 makes an even bigger mess of the directory containing
      the .sln file, so the incentive is bigger.  Plus, we have to
      disable several things to get VC++ 2003 to build MySQL++ now,
      so we need a special 2005+ version of the project files for a
      complete build, if the user has one of the newer compilers.

    o ...plus dozens of small bug fixes and internal enhancements,
      many documentation improvements, and expansion of support for
      newer operating systems and compilers.


2.3.2, 2007.07.11 (r1669)

    o Previous release's const_string change caused more problems
      than it fixed.  This release contains the real fix. :)

    o New Connection::set_option() handling deals with the multi
      statements option correctly again.  examples/multiquery now
      runs again as a result.

    o Added new unit testing script, called dtest.  See the
      HACKERS file for details.  (This tool caught the previous
      two problems!)

    o Squished a GCC pedantic warning.  Thanks for the patch go to
      Andrew Sayers.


2.3.1, 2007.07.10 (r1659) The "After the Fireworks" release

    o const_string objects now keep a copy of their data, not
      just a pointer to it.  This is less efficient, but necessary
      to allow SSQLS to work with BLOBs.  Without this, we were
      seeing segfaults due to accessing freed memory pointed to
      by the const_string, because the underlying object went
      out of scope.

    o Fixed many more potential embedded null handling problems
      in manip.h.

    o MySQL++ can now optionally reference MySQL C API headers as
      being in a mysql subdirectory, a common thing on *ix systems,
      by defining MYSQLPP_MYSQL_HEADERS_BURIED before #including
      mysql++.h.

    o Restored ColData_Tmpl<T>::get_string(), removed in v2.3.0,
      along with warnings in the docs saying why you don't want
      to use it, and what your alternatives are.

    o VC++ and MinGW builds now define the HAVE_MYSQL_SSL_SET
      macro, which lets you use the C API's SSL features.
      This assumes your C API library does actually have these
      features enabled, which is the case with the official binary
      releases on Windows.  (Builds on *ix systems continue to
      test for these features at configure time.)

    o Fixed simple examples-only Makefile generation, for RPMs.


2.3.0, 2007.07.02 (r1645)

    o Added Query::for_each() and Query::store_if() methods
      proposed by Joel Fielder, and added examples for each.

    o It's now possible to store BLOB data in an SSQLS.  It's not
      foolproof, so added a section to the user manual (5.9) to
      document the method.  Also, changed examples/cgi_jpeg to use
      this new mechanism, instead of the ugly "raw row data" method
      it used to use.

    o Revamped Connection::set_option() handling.  These options
      used to be queued up, and applied only just before actually
      establishing the connection.  This made error reporting less
      helpful because the diagnostic was separated from the cause.
      Plus, the error messages were misleading to begin with.  Now,
      set_option() takes effect immediately if the connection is not
      yet up (excepting one special option that can actually be set
      after the connection is up) and issues better diagnostics when
      it detects errors.

    o Connection::connect() used to set a few options in such a
      way that the user couldn't override them.  Now it's smart enough
      to set them with the desired default values only when we see
      that the user hasn't given them other values.

    o SQLString can now be initialized from a mysqlpp::null,
      giving a "NULL" string.  This is useful for template queries.
      Patch by Michael Hanselmann.

    o resetdb error message about mixing library and header version
      numbers is now more explicit.

    o Changed BadConversion exception's "what" message text to be
      more like the other exceptions.  The inconsistency lead one
      to incorrectly copy-paste code from another exception handler,
      expecting it to behave the same way.  Now it does.

    o Added Row::raw_size(), as a shortcut for Row::at().size().

    o ssqls-pretty now detects when it's being run from within
      the MySQL++ distribution tree and gives a different -I flag
      to the compiler, so that it picks up the distribution headers
      instead of those that may be on the system already.

    o The quote manipulator now works for char[] correctly.
      Thanks for this patch go to Andrew Sayers.  (It's always
      worked for char*, but C++ doesn't consider that to be the
      same type, so it used the generic quote handling path,
      which doesn't do anything for char[].)

    o Fixed a build bug on older Solaris versions where the
      test for the C API library was erroneously failing, stopping
      the configuration process.

    o Simplified mysql_shutdown() level argument detection.
      Already had to do a version number ifdef check for the
      Windows case, so there's really no point to doing it with
      autoconf on Unixy platforms.  Moved version number check
      into lib/connection.cpp, and nuked the separate autoconf and
      Windows tests.

    o Removed dependency of sql_types.h on myset.h and (indirectly)
      datetime.h.  Now we only define sql_* typedef aliases for those
      MySQL++ types if the headers are included before sql_types.h.

    o Fixed a typo in one of the storein_sequence() template
      overloads, which is apparently rarely (or never?) used, because
      no one reported the compiler error you'd get if you tried.

    o Fixed a few more embedded null handling problems.

    o ColData used to keep two copies of all data it held.
      Now it keeps just one.

    o Fixed install.bat script to track the unified Bakefile change
      and the lack of separate debug and release builds under MinGW.

    o Yet another STLport + Query memory leak fix.

    o Squished a warning in newer GCCs having to do with identifier
      shadowing.  Patch by Jonathan Wakely.

    o Fixed a null-termination bug in Query::parse().  If you
      somehow constructed a query string without a terminating null
      character, then tried to parse it as a template query, it could
      walk off the end of the string.  Patch by Worster Chen.

    o Removed MYSQLPP_EXPORT tag from FieldNames and FieldTypes
      class declarations, as this can cause problems in programs
      that use vector<string> in VC++.  It has to do with multiply
      defined templates, since these classes derive from that
      template, and VC++ can't resolve the conflict without help.
      Since these classes aren't actually used outside the library,
      this shouldn't cause a problem.  Patch by Nils Woetzel.

    o Partial fix to Doxygen PDF build on RHEL4 and 5.  Needs
      hand-coaxing to complete successfully on RHEL4, and doesn't
      yet work at all on RHEL5.

    o Shortened the "no*" options to the bootstrap script, so that
      the usage message fits on a single line.

    o Added "nodoc" bootstrap script option, for disabling the
      documentation build during the dist target build.  Allows for
      building binary RPMs on CentOS 5.0, where doc building is
      currently broken.

    o Removed the updel example program.  It was kind of silly,
      and if you were to rewrite it today, you'd use for_each() anyway.

    o Lots of documentation improvements.


2.2.3, 2007.04.17 (r1538) The "Tax Day" release

    o Previous version left examples/vstudio/* out of the tarball
      by accident.

    o Improved generation of RPM temporary build directory path
      name generation.  Was using a hacked variant of the Fedora
      Packaging Guidelines' second best choice.  Now we're using
      the choice they recommend most highly, without changes.

    o Removed unnecessary resources from vstudio/wforms example.

    o Minor URL fix in refman


2.2.2, 2007.04.13 (r1526) The "Nervousmaking Friday the 13th" release

    o More small fixes to embedded null handling in Query.

    o Fixed a bug in single-parameter template query handling.

    o Added tquery example, to demonstrate proper use of template
      queries.  Previously, resetdb was the only exemplar, and
      it wasn't really suited for that.  This example also tests
      the previous item.

    o Added examples/vstudio/mfc, allowing us to improve the way
      we demonstrate Unicode handling.  Old way wasn't realistic.
      On *ix, people will depend on the terminal code to handle
      UTF-8.  On Windows, users are almost certain to be writing
      a GUI program, which requires different Unicode handling
      than the old examples showed.

    o Removed explicit Unicode conversion stuff from command line
      examples, and reworked the Unicode chapter in the user
      manual.
    
    o Added examples/vstudio/wforms to show integration with
      C++/CLI and Windows Forms.  Documented this in README.vc.

    o Rewrote load_file and cgi_image examples to be more
      useful, renaming them to load_jpeg and cgi_jpeg along
      the way.  Also, resetdb now creates a second table in the
      sample database for these two examples' use.  Also, added
      examples/logo.jpg to the distribution as sample data for
      these examples.

    o Limited the ostream base class casting stuff in Query to
      VC++ 2003, which is the only platform that really needed it.
      VC++ 2005 emits a warning with that hack in place, and on
      other platforms it's just replicating work that the compiler
      does already.

    o Added library version information to main library target
      so that systems that version shared libraries work as
      expected.  Thanks for this patch go to Jack Eidsness.

    o Merged much of the diffs between Remi Collet's RPM spec file
      into the official one.

    o Reorganized the doc subdir a bit.  Generated HTML is now all
      under doc/html instead of scattered under other subdirs,
      and renamed doc/README.mysql++ to doc/README.manuals.

    o Improvements to top-level manual building make targets:
      manuals now only rebuild at need, it's easier to request
      a rebuild of all manuals, and we force a rebuild attempt
      before building the distribution tarball so we don't ship
      outdated manuals.

    o Added ability to run examples under gdb using exrun,
      using same mechanism as we currently have for valgrind.
      Thanks for this patch go to Michael Hanselmann.

    o Added "Important Underlying C API Limitations" chapter to the
      user manual, to cover problems we keep seeing on the
      mailing list that are the result of ignorance of the way
      libmysqlclient behaves, not bugs MySQL++ is really in a
      position to fix.


2.2.1, 2007.02.28 (r1433)

    o Fixed the new localtime() alternative selection code
      for VS2003 and various uses of STLport.

    o No longer inserting a null character into the query stream
      on calling one of the preview() functions.  This was harmless
      in v2.1, which used C strings more extensively, but began
      causing problems in v2.2 due to its wider use of C++ strings.

    o Fixed a bug in the Connection copy ctor where it didn't
      completely initialize the object.

    o Optimized Query::preview_char() a bit.  Patch by Jonathan
      Wakely.

    o Reordered directory list used by autconf when locating the
      MySQL C API library.  The list is now ordered with the
      most likely locations for the library first, so we're less
      distracted by incorrect libraries.  This fixes a specific
      build error under RHEL4 with recent versions of MySQL 5.0.


2.2.0, 2007.01.23 (r1417)

    o ColData, const_string, and SQLString can now be constructed
      with an explicit length parameter.  Furthermore, Query
      class's execute(), store() and use() call chains terminate
      in a version taking an explicit length parameter, instead
      of one taking a simple C string.  Together, this means
      that it's now easier to handle data from the SQL server
      containing nulls.  The library is almost certainly not yet
      capable of handling embedded nulls in all cases, but this
      is a big first step towards that.

    o Can now construct a DateTime object from a time_t, and
      convert a DateTime back to a time_t.  Patch by Korolyov Ilya.

    o Changed the way we're handling exported functions in the
      Windows DLL case so that it works more reliably under MinGW.

    o Added proper copy semantics to Connection, so that you get a
      new connection with the same parameters, not just a bitwise
      copy of the object.

    o Using an explicitly thread-safe variant of localtime() for
      time conversions where one is available.

    o Removed ListInsert template from myset.h.  This wasn't used
      within the library, and was never documented, so I'm betting
      that no one actually uses it.

    o Result::copy() was not copying the exception flag in
      all cases.  Fix by Steven Van Ingelgem.

    o Added exrun shell script and exrun.bat files to distribution,
      to avoid linkage errors when running the examples while
      you still have an older version of MySQL++ installed.

    o Renamed MYSQLPP_LIB_VERSION to MYSQLPP_HEADER_VERSION, as
      what it really encodes is the version number in the mysql++.h
      file you're using, not the actual library version number.

    o Added mysqlpp::get_library_version(), which returns the
      library version number at build time.  Between this and
      the header version constant, you can check that you're not
      mixing MySQL++ header and library versions.

    o resetdb example uses these new version number affordances to
      double-check that you're not mixing libraries and headers
      from different versions.  This happens easily unless you
      take care of it (such as by using exrun) when you have one
      version of MySQL++ installed and you're trying to build and
      test a new version without blowing away the old one first
      or overwriting it.

    o No longer using recursive Makefiles on Unixy platforms
      or split lib + examples project files on VC++.  Everything is
      handled by a single top-level Makefile or project file, which
      is simpler for the end user, and makes better dependency
      management possible.

    o When looking for the MySQL C library on systems using
      autoconf, looking in .../lib64 wherever we are also looking
      in .../lib.

    o RPM build process no longer depends on Bakefile.  It means
      you have to build the examples when building an RPM even
      though they're never used within the RPM, but it's a better
      tradeoff in my opinion.

    o Updated include and library paths on Windows to reflect
      changes in the most recent MySQL installers.

    o Merged lib/defs.h and lib/platform.h into new file,
      lib/common.h.  Just cleans up the library internals.

    o Fixed build errors on Windows due to recent changes in MySQL.

    o Fixed a few memory leaks and double-deletes in Query class.

    o Fixed compatibility with STLPort's string implementation.
      Patch by dengxy at cse.buaa.edu.cn.

    o Fixed a compatibility problem between Set<> template and
      SSQLS.  Patch by Korolyov Ilya.

    o Fixed build bug in SQLQueryParms due to a character
      signedness issue on PowerPC with GCC.  Patch by Michael
      Hanselmann.

    o ~Transaction() can no longer throw exceptions.  It'll just
      quietly eat them, to avoid program termination.  Fix
      suggested by Alex Burton.

    o Fixed thread safety testing in autoconf case, accidentally
      broken during v2.1.0 development cycle.

    o Using Doxygen 1.5.1 to generate documentation.


2.1.1, 2006.04.04 (r1289)

    o MinGW and Cygwin will now build and link to mysqlpp DLLs.

    o Fixed bug in Query, causing it to initialize the "throw
      exceptions" flag incorrectly.  Thanks for this patch go to
      Joel Fielder.

    o Added -v flag for custom.pl script, which turns off the
      multiply-defined static variable fix.  Needed for VS 2003,
      which doesn't support variadic macros.  Also, added
      a diagnostic to detect the need for the -v flag, and
      suppressed the test for this feature in examples/util.cpp.


2.1.0, 2006.03.24 (r1269)

    o Converted automake and makemake files to their equivalents in
      Bakefile format.

    o Added the Transaction class, which makes it easy to use
      transaction sets in MySQL++.

    o Added xaction example to test new Transaction class.

    o Resetdb example now creates its example table using the
      InnoDB storage engine, in order to test the new transaction
      support.  Resetdb also declares the table as using UTF-8
      text; this doesn't change anything, but it does correctly
      document what we're doing.

    o Added sql_types.h header, containing C++ typedefs
      corresponding to each MySQL column type.  Using those new
      types in the type_info module, and in the SSQLS examples.

    o Replaced the way we were handling the template query
      version of Query member functions, to allow an arbitrary
      number of template query parameters.  By default, we
      now support 25 parameters, up from the old limit of 12.
      It's now possible to change just one number, run a script,
      and have a new limit.

    o Connection class does a better job of returning error
      messages if you call certain member functions that depend
      on a connection to the server before the connection is
      established.

    o Updated libmysqlclient.def for newer versions of MySQL.  (Fixes
      build errors having to do with mysql_more_results() and
      mysql_next_result().

    o Replaced final use of strcpy() with strncpy().

    o custom.pl now runs without complaint in strict mode, with
      warnings turned on.  Thanks for this patch go to "Waba".

    o Fixed a bug in custom.pl where incorrect code would be
      generated for some SSQLS set() methods.  Thanks for this
      patch go to "Waba".

    o SSQLS structures now support long and unsigned long fields.
      Thanks for this patch go to "Waba".

    o It's now possible to put SSQLS definitions in a header
      file used by multiple modules in a program without
      getting multiple static member definition errors.  See the
      documentation for details.  Thanks for this patch go to
      Viktor Stark.

    o Moved the definition of the 'stock' SSQLS out of the
      custom*.cpp example files and into a new stock.h file.
      Also, #including that file in the util module to test out
      the new SSQLS multiple static definition fix.

    o Using all of the digits of precision guaranteed by the
      IEEE 754 spec when stringizing floating point numbers
      to build queries.  Previously, we would use the platform
      default, which can be as few as 6 digits.

    o Removed lib/compare.h.  Not used within the library, never
      documented, and nobody seems to want to defend it.


2.0.7, 2005.11.23 (r1147)

    o Added explicit mysqlpp namespace qualifiers to generated code in
      custom*.h so you can use SSQLS in places where it doesn't make
      sense to say "using namespace mysqlpp" before the declaration.
      Also updated some of the examples to not have this "using"
      declaration to make it clear to users that it isn't needed, if you
      want to use explicit namespace qualifiers as well.  Thanks for
      this patch to Chris Frey.

    o Removed an apparently useless unlock() call from ResUse; there is
      no nearby lock() call, so if this unlock() is in fact necessary,
      it shouldn't be here anyway, because the two calls should be
      nearby each other.  Thanks for this patch to Chris Frey.

    o Fixed Query ostream initialization bug affecting SunPro CC (at
      least).  While this bug violates the Standard, it doesn't affect
      many real compilers because they don't enforce this rule.  Fixed
      by Chris Frey.

    o Previously, we only used the C99 style "long long" support when
      building under GNU CC.  This is now the default.  This should
      allow the code to work under SunPro CC.

    o Added another dynamic cast needed for proper Query ostream
      subclass overloading under VC++.  (7.1 at least...)

    o Detecting whether MySQL is built with SSL support on platforms
      using autotools.  Needed on some old Sun systems, for instance.
      Thanks for this patch to Ovidiu Bivolaru.

    o Fixed a potential memory bug in ColData's conversion to SQL null.

    o Many minor packaging tweaks.  (README clarifications, file
      permission fixes, better adherence to GNU packaging standards,
      etc.)

    
2.0.6, 2005.09.28 (r1123)

    o Fixed makemake.bat so it works on cmd.exe, not just 4NT.

    o Documentation fixes.


2.0.5, 2005.09.13 (r1114)

    o Visual C++ build now requires GNU make.  It is tested to work
      with either the Cygwin or the MinGW versions.  The previous
      version of MySQL++ used nmake.  This change enabled the
      following features:

        o Debug and Release versions are both built into
          separate subdirectories.

        o Dependency tracking for release version works
          correctly now.  (Previously dependencies worked
          only for debug version.)

        o 'make clean' removes release version binaries
          in addition to debug versions.

    o MinGW makemake support updated to support new release/debug
      subdirectory system.  This is probationary support, since
      this code currently can't be built as a DLL.  As a result,
      it is no more useful than the Cygwin version, for licensing
      reasons.

    o Several fixes to allow building on Solaris 8.  These fixes may
      also help on other SVR4-derived systems.

    o Removed Borland C++ makemake support, because this version
      of the library does not work completely, and there seems
      to be almost no user interest in fixing it.
      
    o Clarified "Handling SQL Nulls" section of user manual's
      Tutorial chapter.


2.0.4, 2005.08.29 (r1076)

    o Made mysql_shutdown() second parameter autoconf check less
      sensitive to compiler pedantry.

    o VC++ library Makefile is now smart enough to re-create the
      import library, if it is deleted while leaving the DLL alone.

    o Added libmysqlclient.def to tarball.

    o Reworked most of the top-level README* files.

    o Renamed LGPL file to LICENSE.


2.0.3, 2005.08.25 (r1060)

    o Visual C++ makemake system updated to build both debug and
      release versions of library DLL.

    o Fixed bug in simple1 example that caused crashes on Windows.

    o Doing UTF-8 to ANSI text translation in simple examples now.

    o Previous two releases built libmysqlpp with wrong soname on
      autotools-based systems.  Fixed.


2.0.2, 2005.08.18 (r1050)

    o Fixes to makemake system for cmd.exe.

    o Fixed the case where the system's C++ library includes an slist
      implementation in namespace std.


2.0.1, 2005.08.17 (r1046)

    o Added new simple1 example, showing how to retrieve just one
      column from a table.  Old simple1 is now called simple2, and
      simple2 is likewise shifted to simple3.

    o Added custom6 example, showing how to do the same thing with
      SSQLS.

    o Updated user manual to cover new examples.

    o Was accidentally shipping Subversion crap with tarball.  Fixed.


2.0.0, 2005.08.16 (r1031) The "Excess Hair Removal" release

    THIS IS NOT A DROP-IN REPLACEMENT FOR MySQL++ v1.7!

    At minimum, you will have to recompile your program against
    this library.  You may also have to make code changes.
    Please see the "Incompatible Library Changes" chapter of
    the user manual for a guide to migrating your code to this
    new version:

        http://tangentsoft.net/mysql++/doc/html/userman/breakages.html

    o The library's shared object file name (soname) scheme has
      changed.  (This mainly affects POSIX systems.)
      
      The soname for the last 1.7.x releases of MySQL++ was
      libmysqlpp.so.4, meaning the fourth version of the library's
      application binary interface (ABI).  (The first ABI version
      in this scheme was that provided by 1.7.9.)  MySQL++
      2.0.0's soname is libmysqlpp.so.2.0.0.  Since the dynamic
      linker setup on some systems will create a symlink to
      that file called libmysqlpp.so.2, it's possible that this
      library could be confused with that for MySQL++ 1.7.19
      through .21, which also used this number.  Do not install
      this library on a system which still has binaries linked
      against that version of the library!

      The new scheme is {ABI}.{feature}.{bug fix}.  That is,
      the first number changes whenever we break the library's
      binary interface; the second changes when adding features
      that do not break the ABI; and the last changes when the
      release contains only internal bug fixes.  This means
      that we will probably end up with MySQL++ 3.0 and 4.0 at
      some point, so there will be further soname conflicts.
      Hopefully we can put these ABI changes off long enough
      to avoid any real problems.

    o autoconf now installs headers into $prefix/include/mysql++,
      instead of $prefix/include.  If you were using the
      --includedir configure script option to get this behavior
      before, you no longer need it.

    o Linux binary RPMs will henceforth include only the
      libmysqlpp.so.X.Y.Z file, and create any short names
      required, to allow multiple versions to be installed at
      once.  Currently, you cannot install two MySQL++ library
      RPMs at once, because they both have /usr/lib/libmysqlpp.so.X,
      for instance.

    o Replaced the Visual C++ and Borland C++ project files with
      a new "makemake" system, which creates Makefiles specific
      to a particular toolchain.  This new mechanism also supports
      MinGW and generic GCC-on-*ix.  This was done partly to reduce
      the number of places we have to change when changing the
      file names in MySQL++ or adding new ones, and partly so we're
      not tied to one particular version of each of these tools.

    o VC++ Makefiles create a DLL version of the library only
      now, so there's no excuse for LGPL violations now.
      This same mechanism should make DLL builds under other
      Windows compilers easy.

    o Added Connection::enable_ssl(), which enables encrypted
      connections to the database server using SSL.

    o Connection::create_db() and drop_db() now return true on
      success, not false.

    o Connection::create_db() and drop_db() use Query::exec()
      now, for efficiency, rather than Query::execute().

    o Removed Connection::infoo().  Apparently just there to
      save you from a typo when calling the info() method, since
      it was a mere alias.

    o Renamed Connection::real_connect() to connect(), gave
      several more of its parameters defaults, and removed old
      connect() function.  Then changed user manual and examples
      to use new APIs.

    o Replaced Connection::read_option() with new set_option()
      mechanism.  The name change matches the method's purpose
      better.  Functional changes are that it returns true on
      success instead of 0, it supports a broader set of options
      than read_option() did, and it enforces the correct option
      argument type.

    o You can now call Connection::set_option() before the
      connection is established, which will simply queue the option
      request up until the connection comes up.  If you use this
      feature, you should use exceptions, because that's the only
      way an option setting failure can be signalled in this case.

    o Removed query-building functions (exec*(), store*(),
      use()) from class Connection, and moved all the implementation
      code to class Query.  Query no longer delegates the final
      step of sending the query to the database server to
      Connection().

    o Added Connection::enable_ssl(), for turning on SSL support on
      a connection.

    o Extracted exception disabling mechanism out of the many
      classes that had the feature into a new OptionalExceptions
      base class, which all classes having this feature now
      derive from.  Also, removed all per-method exception
      handling flags.  Finally, added NoExceptions class.  With
      all of these changes, there is now a common way to disable
      exceptions with fine granularity on all objects that
      support the feature.

    o All custom MySQL++ exceptions now derive from the new
      Exceptions class.  This regularizes the exception interface
      and allows you to use a single catch() block if you want.

    o The "throw exceptions" flag is passed from parent to child
      in all situations now.  (Or if not, please report it as
      a bug.) This fulfills a promise made in the v1.7.9 user
      manual, with the cost being that some programs will see
      new exceptions thrown that they're not expecting.

    o Added a bunch of new exception types: BadOption,
      ConnectionFailed, DBSelectionFailed, EndOfResults,
      EndOfResultSets, LockFailed, and ObjectNotInitialized.
      Some of these replace the use of BadQuery, which in v1.7.x
      was a kind of generic exception, thrown when something more
      specific wasn't available.  Beware, this means that programs
      may start crashing after recompiling them under v2.0 due to
      uncaught exceptions, if they were only trying to catch BadQuery.

      There are additional instances where the library will
      throw new exceptions.  One is when calling a method that
      forces the internals to use an out-of-bounds index on a
      vector; previously, this would just make the program
      likely to crash.  Another is that the library uses the
      BadFieldName exception -- created in v1.7.30 -- in more
      apropos situations.

    o Renamed SQLQueryNEParms to BadParamCount, to match naming
      style of other concrete exception types.

    o Extracted lock()/unlock() functions from Connection and
      Query classes into a new Lockable interface class.  Locking
      is implemented in terms of a different class hierarchy, Lock,
      which allows multiple locking strategies with a single ABI.

    o Removed ResUse::eof().  It's based on a deprecated MySQL
      C API feature, and it isn't needed anyway.

    o Removed arrow operator (->) for iterator returned by Fields,
      Result and Row containers.  It was inherently buggy, because
      a correct arrow operator must return the address of an
      object, but the underlying element access functions in these
      classes (e.g. at()) return objects by value, of necessity.
      Therefore, this operator could only return the address of
      a temporary, which cannot be safely dereferenced.

    o Returned Row subscripting to something more like the
      v1.7.9 scheme: there are two operator[] overloads, one for an
      integer (field by index) and another for const char* (field
      by name).  lookup_by_name() has been removed.  Because row[0]
      is ambiguous again, added Row::at() (by analogy with STL
      sequence containers), which always works.

    o Collapsed two of the Row::value_list*() overloads into
      two other similar functions using default parameters.
      This changes the API, but the removed functions aren't
      used within the library, and I doubt they are used outside,
      either.

    o Merged RowTemplate into Row.

    o Merged SQLQuery class into Query class.

    o Query is now derived from std::ostream instead of
      std::stringstream, and we manage our own internal string
      buffer.

    o Moved SQLParseElement and SQLQueryParms into their own
      module, qparms.

    o Added multiple result set handling to Query.  MySQL 4.1
      and higher allow you to give multiple SQL statements in a
      single "store" call, which requires extensions to MySQL++
      so you can iterate through the multiple result sets.  Also,
      stored procedures in MySQL 5.0 reportedly return multiple
      result sets.  Thanks for the initial patch go to Arnon Jalon;
      I reworked it quite a bit.

    o Query::storein*() now supports more varieties of the
      nonstandard slist comtainer.  (Singly-linked version of
      STL std::list.)

    o Template query mechanism and user manual had several
      mismatches.  Made manual match actual behavior, or
      made library match documented behavior, as apropriate.
      Initial patch by Jürgen MF Gleiss, with corrections and
      enhancements by Warren Young.

    o Collapsed mysql_* date and time base classes' methods and
      data into the subclasses.  Also, DateTime no longer derives
      from Date and Time; you could get away with that in the
      old hierarchy, but now it creates an inheritance diamond,
      and allows unsupported concepts like comparing a Time to
      a DateTime.

    o Removed "field name" form of Row::field_list().  It was
      pretty much redundant -- if you have the field names, why
      do you need a list of field names?

    o ColData can convert itself to bool now.  Thanks for this
      patch go to Byrial Jensen.

    o Removed simp_list_b type; wasn't being used, and doesn't
      look to be useful for end-user code.

    o Several methods that used to take objects by value now
      do so by const reference, for efficiency.

    o Several variable and function renamings so that MySQL++
      isn't needlessly tied to MySQL.  Even if we never make
      the library work with other database servers, there's
      little point in tying this library to MySQL blindly.

    o Renamed all private data members of MySQL++ classes to
      have trailing underscores.

    o 'private' section follows 'public' section in all classes
      now.

    o Removed mysql++.hh and sqlplus.hh backwards-compatibility
      headers.

    o Added copy ctors to Date/Time classes so that they will
      work in SSQLS under GCC 4.0.0.  Without these, the compiler
      couldn't make the conversion from raw MySQL row data.

    o Fixed a bunch of GCC 4.0 pedantic warnings: added virtual
      dtors to all base classes, calling base class ctors from leaf
      classes, etc.

    o All warnings fixed under VC++ at warning level 3.  (Mostly
      harmless signedness and integer conversion stuff.)

    o Updated LGPL license/copyright comments at the top of
      several files to use FSF's new physical address.

    o Relicensed user manual under a close variant of the Linux
      Documentation Project License, as it's designed for
      documentation, which the LGPL is not.  Permission for this
      received from Kevin Atkinson and MySQL AB.

    o Added ABI and API breakages chapter to user manual.  It
      is basically a subset of this ChangeLog, with only the
      information an end-user must know when migrating between
      versions.

    o Reworked user manual's DocBook code quite a bit after
      reading Bob Stayton's book "DocBook XSL" 3/e.  Better handling
      of stylesheets, taking advantage of some superior DocBook
      features, prettier output (especially the HTML version), etc.

    o Rewrote doc/userman/README to make it clearer how to get
      started contributing to the user manual.  It's essentially a
      "getting started with DocBook" guide now!

    o Lots of small text improvements to user and reference
      manuals.  Aside from the obvious tracking of library changes,
      made a bunch of minor style and clarity improvements.

    o Added CSS stylesheets for userman and refman to
      make the HTML versions of each a) not ugly; and b) match
      tangentsoft.net.  (Yes, some may say that these are incompatible
      goals....)

    o Standardized exception handling code in the examples that
      use it.

    o Fixed a potential memory leak due to exceptions thrown from
      ResUse.  Thanks for this patch go to Chris Frey.

    o Using new "no exceptions" feature of library in simple1
      example, so it is now truly simple.

    o simple1 example no longer depends as much on util module, so
      that all of the important code is in one place.  Makes
      learning MySQL++ a little less intimidating.

    o Added new simple2 and usequery examples, to demonstrate
      the proper way to handle a "use" query, with exceptions
      disabled, and not, respectively.  Added them to the user
      manual, in the appropriate place.

    o Refactored the "print stock table" example functions
      again, to make code using them clearer.

    o UTF-8 to UCS-2 handling in examples is now automatic on
      Windows.

    o Removed debug code from Windows Unicode output examples
      that slipped into previous release.

    o resetdb example is now clearer, and more robust in the
      face of database errors.

    o Simplified connect_to_db() in examples' util module.

    o Added sample autoconf macro for finding MySQL++ libraries, for
      people to use in their own autotools-based projects.

    o Lots and lots of minor cleanups not worth mentioning
      individually...


1.7.40, 2005.05.26 (r719)

    o Multiple item form of insert() now works if you're using the
      SQLQuery class, or its derivative, Query.  Thanks to Mark
      Meredino for this patch.

    o Fixed a bug in const_string::compare(), in which MySQL++
      would walk off the end of the shorter of the two strings.
      All was well if the two were the same length.

    o ResUse::operator=() now fully updates the object, so it's more
      like the behavior of the full ctor.

    o All source files now contain a license and copyright statement
      somewhere within them.

    o Optimized mysql++.h a bit: it now #includes only the minimum set
      of files required, and there is now an idempotency guard.
      This improves compile times a smidge, but mainly it was
      done to clean up the generated #include file graph in the
      reference manual.  Before, it was a frightful tangle because
      we #included everything except custom*.h.

    o Constness fix in MySQL++ date/time classes to avoid compiler
      warnings with SSQLS.  Thanks to Wolfram Arnold for this patch.

    o Fixed some compiler warnings in custom*.h.  Thanks to Chris Frey
      for this patch.

    o Added "Submitting Patches" and "Maintaining a Private CVS
      Repository" sections to the HACKERS file.  Thanks to Chris
      Frey for the source material for these sections.  The HACKERS
      file was improved in several other ways at the same time.

    o PDF version of user manual no longer has links to the reference
      manual.  They were ugly, and they were broken anyway due to the
      way we move the PDFs after generating them.  If you want
      interlinked manuals, use the HTML version.

    o PDF version of user manual now has hard page breaks between
      chapters.

    o Removed complic1 example.  Wasn't pulling its own weight.
      Everything it is supposed to demonstrate is shown in other
      examples already.

    o Refactored print_stock_table() in examples/util module to be
      four functions, and made all the examples use various of
      these functions where appropriate.  Before, several of
      the examples had one-off stock table printing code because
      print_stock_table() wasn't exactly the right thing, for one
      reason or another.  One practical problem with this is that
      some of the examples missed out on the recent Unicode updates;
      now such a change affects all examples the same way.

    o Since so many of the examples rely on the util module, the user
      manual now covers it.  The simple1 example in the user manual
      didn't make much sense before, in particular, because it's
      really just a driver for the util module.

    o Added custom5 example.  It shows how to use the equal_list()
      functionality of SSQLS.  Thanks to Chris Frey for the original
      version of this program.  (I simplified it quite a bit after
      accepting it.)

    o New user manual now covers the value_list(), equal_list() and
      field_list() stuff that the old manual covered but which was
      left out in previous versions of the new manaul.  Most of the
      examples are the same, but the prose is almost completely new.
      This new section includes the custom5 example.

    o Every declaration in MySQL++ is now documented in the reference
      manual, or explicitly treated as "internal only".

    o Improved docs for MySQL++'s mechanism to map between MySQL
      server types and C++ types.  Initial doc patch by Chris Frey,
      which I greatly reworked.

    o Improved a lot of existing reference manual documentation while
      adding the new stuff.

    o Expanded greatly on the exception handling discussion in the user
      manual.

    o Added all-new "Quoting and Escaping" section to the user
      manual's Tutorial chapter.  Moved some existing comments on
      quoting and escaping around and added some new ones to other
      sections as a result.

    o Added all-new "Handling SQL Nulls" section to the user manual's
      Tutorial chapter.

    o Many improvements to the Overview section of the user manual.

    o Row::operator[] reference now explains the right and wrong way to
      use the values it returns.  This is in response to a mailing list
      post where someone was incorrectly using this feature and getting
      a bunch of dangling pointers.

    o Updated Doxyfile so 1.3.19.1 parses it without warnings.  Still
      works with versions back to 1.2.18, at least.  (These are
      the versions shipped with Fedora Core 3 and Red Hat Linux 9,
      respectively.)

    o Using a superior method to make Doxygen ignore certain sections
      of the source code.  Between this change and the fact that
      everything not so ignored is documented, Doxygen no longer
      generates any warnings.

    o Lots of code style updates.  Everything should now be consistently
      formatted.


1.7.35, 2005.05.05 (r601) The "Cinco de Mayo" release

    o Added a "how to use Unicode with MySQL++" chapter to the user
      manual.  (Too bad "Cinco de Mayo" doesn't have any accented
      characters.  That would be just _too_ precious.)

    o VC++ examples now use the Unicode Win32 APIs, so they can display
      Unicode data from MySQL++.

    o Added an optional conversion function to examples/util.cpp to
      handle the conversion from UTF-8 to UCS-2 on Win32.

    o Moved "brief history of MySQL++" from intro section of refman to
      intro section of userman.

    o Lots of small bits of documentation polishing.
    
    o Made some minor constness fixes.  Thanks to Erwin van Eijk
      for this patch.

    o Made some warning fixes for GCC 4.0.  Not all warnings are
      fixed, because some of the needed changes would break the ABI.
      Thanks to Chris Frey for this patch.

    o Added lib/Doxyfile to distribution.
    

1.7.34, 2005.04.30 (r573)

    o Added a multiple-insert method for Query, which lets you insert
      a range of records from an STL container (or the whole thing,
      if you like) in a single SQL query.  This is faster, and it
      reduces coding errors due to less repetition.  Thanks to Mark
      Meredino for the patch.

    o Reference and user manual now get rebuilt automatically when
      required.  (E.g. on 'make dist', or explicitly now through 'make
      docs'.)

    o Made it easier to change the maximum number of SSQLS data members
      in generated custom-macros.h file.  It used to be hard-coded in
      several places in lib/custom.pl; now it's a variable at the top of
      the file.

    o Changed default SSQLS data member limit to 25, which is what it
      has been documented as for a long time now.  It was actually 26
      within custom.pl.

    o Fixed a regression in previous version.

    o Trimmed some fat from the distribution packages.

    o Some more small doucmentation improvements.


1.7.33, 2005.04.29 (r555)

    o Worked around an overloaded operator lookup bug in VC++ 7.1
      that caused SSQLS insert, replace and update queries to get
      mangled.  (Symptom was that custom2 and custom3 examples didn't
      work right.)  Thanks to Mark Meredino for digging up the
      following, which explains the problem and gives the solution:

      http://groups-beta.google.com/group/microsoft.public.vc.stl/browse_thread/thread/9a68d84644e64f15

    o Some VC++ warning fixes.

    o Major documentation improvements:
    
        o Using DocBook for user manual and Doxygen for reference
          manual.  The former now references the latter where
          useful.

        o Split out HACKERS and CREDITS files from main README,
          and improved remaining bits of README.

        o Moved the text from the old v1.7.9 LaTeX-based
          documentation over into the new systems, and reworked
          it to more closely resemble English.

        o Added a lot of new material to documentation, and
          simplified a lot of what already existed.

        o Documentation is now being built in HTML and PDF forms.

    o ebuild file updated to take advantage of recent configure script
      features.  Thanks to Chris Frey for this patch.



1.7.32, 2005.03.10 (r479)

    o Example building may now be skipped with --disable-examples
      configure script flag.

    o Changed stock items added in resetdb.  One is now UTF-8 encoded,
      to show that basic use of Unicode with MySQL++ is easy, yet not
      foolproof.  (See formatting of table on systems where cout isn't
      UTF-8 aware!)  Other stock items now follow a theme, for your
      amusement.  :)

    o custom3 example now changes UTF-8 item's name to the 7-bit ASCII
      equivalent.  Previously, this example would fix a spelling error
      in the table.

    o resetdb example now says 'why' when it is unable to create the
      sample database.

    o Small formatting change to print_stock_table(), used by several
      examples.

    o Was issuing a VC++-specific warning-disable pragma when built by
      any Windows compiler.  Fixed.
    

1.7.31, 2005.03.05 (r462) The "Inevitable Point-one Followup" release

    o Check for threads support must now be explicitly requested via
      configure script's new --enable-thread-check flag.

    o Fix for contacting MySQL server on a nonstandard port number.
      Thanks to Chris Frey for this patch.

    o Example programs using standard command line format now accept a
      fourth optional parameter, a port number for the server.  Thanks
      to Chris Frey for this patch.

    o One more g++ 3.4 pedantic warning fix by Chris Frey.

    o Exception handling in resetdb is no longer nested, because you'd
      get a segfault on some systems when an exception was thrown from
      one of the inner try blocks.

    o Improvements to Connection class's handling of locking mechanism.
      Concept based on patches by Rongjun Mu.

    o Implemented the declared-but-never-defined Query::lock().  Thanks
      to Rongjun Mu for this patch.
    
    o Cleaned up some unclear if/else blocks in connection.cpp by
      adding explicit braces, correct indenting and putting normal
      code path in the if side instead of the else.


1.7.30, 2005.02.28 (r443) The "Power of Round Numbers" release

    o bootstrap script now accepts a 'pedantic' argument, which sets a
      bunch of CFLAGS that make g++ very picky about the code it
      accepts without warnings.
      
    o Fixed a bunch of things that generated warnings with g++ in
      pedantic mode. Only two warnings remain, having to do with
      floating point comparisons.  (See Wishlist for plans on how to
      deal with these.)  Thanks to Chris Frey for this patch.

    o Split long tests out of configure.in into M4 files in new config
      subdir.  This makes configure.in easier to read.

    o Added preliminary thread support.  Currently, this just means that
      we detect the required compiler and linker thread flags, and link
      against the proper thread-safe libraries.  THERE MAY BE
      UN-THREAD-SAFE CODE IN MYSQL++ STILL!

    o Standard C++ exceptions are the default now.  Old pre-Standard
      exception stuff removed.

    o Row::lookup_by_name() will throw the new BadFieldName exception if
      you pass a bad field name.  Thanks for this patch to Chris Frey.

    o Row::operator[] will throw a Standard C++ out of bounds exception
      by way of std::vector::at() if you pass it a bad index.  Thanks
      for this patch to Chris Frey.

    o Setting Connection::is_connected flag to false on close().
      Previously, is_connected() would continue to return true after
      close() was called.

    o All number-to-string conversion ctors in SQLString class now use
      ostringstream to do the conversion.  Previously, we used
      snprintf(), which isn't available on all systems.  Also, we used a
      C99 format specifier for the "long long" conversion, which is also
      not available on all systems.  This new ostringstream code should
      be platform-independent, finally.


1.7.28, 2005.02.04 (r403)

    o --with-mysql* flags to configure script now try the given
      directory explicitly, and only if that fails do they try
      variations, like tacking '/lib' and such onto it to try and find
      the MySQL includes and libraries.  Thanks to Matthew Walton for
      the patch.

    o Finally removed sql_quote.h's dependence on custom.h, by moving
      the one definition it needed from custom.h to deps.h.  This will
      help portability to compilers that can't handle the SSQLS macros,
      by making that part of the library truly optional.


1.7.27, 2005.01.12 (r395)

    o configure check for libmysqlclient now halts configuration if the
      library isn't found.  Previously, it would just be flagged as
      missing, and MySQL++ would fail to build.

    o Added sql_string.cpp to VC++ and BCBuilder project files.

    o Removed Totte Karlsson's 'populate' example, which never made it
      into the distribution anyway.

    o Removed last vestiges of 'dummy.cpp'.

    o Renamed *.cc to *.cpp in BCBuilder project files.

    o Worked around a BCBuilder C++ syntax processing bug in row.h.


1.7.26, 2004.12.17 (r382)

    o Moved all of the SQLString definitions out of the header and into
      a new .cpp file, reformatted it all, and made the integer
      conversion functions use snprintf() or _snprintf() instead of
      sprintf().  Also, widened some of the buffers for 64-bit systems.

    o Using quoted #include form for internal library headers, to avoid
      some problems with file name clashes.  (The headers should still
      be installed in their own separate directory for best results,
      however.)  Thanks to Chris Frey and Evan Wies for the patch and
      the discussion that lead to it.

    o Removed unnecessary semicolons on namespace block closures.
      Thanks to Evan Wies for this patch.

    o Fixed namespace handling in the legacy headers mysql++.hh and
      sqlplus.hh.  Thanks to Chris Frey for this patch.

    o #including iostream instead of ostream in lib/null.h for
      broader C++ compatibility.  (This may allow MySQL++ to work on GCC
      2.95.2 again, but this is unconfirmed.)

    o Detecting proper mysql_shutdown() argument handling automatically
      in platform.h for the Windows compiler case instead of making the
      user edit the file.  Thanks to Evan Wies for this patch.
    
    o Fixed examples/Makefile.simple to use new *.cpp file naming.

    o Fix to Gentoo ebuild file's exception configure switch handling.
      Thanks to Chris Frey for this patch.

    o Rebuilding lib/custom*.h intelligently now, to avoid unnecessary
      recompiles after running bootstrap script.


1.7.25, 2004.12.09 (r360)

    o Yet more fixes to the --with-mysql-lib and --with-mysql-include
      flags.

    o Added DLLEXPORT stuff to platform.h, hopefully so that someone
      can figure out how to make VC++ make a DLL version of MySQL++.

    o Renamed *.cc to *.cpp.

    o Made 'set -> myset' change in VC++ project files.

    o Some style changes (mostly whitespace) in header files.


1.7.24, 2004.12.08 (r343)

    o Fixed the --with-mysql-lib and --with-mysql-include flags'
      behavior, and extended their search ability to handle one other
      common case.  (Fixed by Steve Roberts)

    o Fixes to put freestanding functions in namespace mysqlpp.  (They
      weren't in the namespace, while all the class member functions
      were.)  This required bumping the ABI version number to 4.
      
    o Renamed set module to myset, to avoid conflicts with Standard C++
      Library's set.h when MySQL++ headers were installed into one of
      the standard system include directories.

    o Renamed all the idempotency guards to make them consistent in
      style and unique to MySQL++.

    o Reformatted all of lib/*.cc.


1.7.23, 2004.11.20 (r333)

    o Query::reset() now empties the stored query string.  If you
      subsequently stored a longer query in the object, you'd overwrite
      the previous query, but otherwise the longer part of the previous
      one would stick out past the new query.

    o We now look to the NO_LONG_LONGS macro only to decide whether to
      fake 64-bit integer support using 32-bit integers.

    o 64-bit integer support under Visual C++ may be working now, using
      that platform's __int64_t type.  This has not been tested.

    o Removed 64-bit integer support for Codewarrior on Mac OS 9 and
      earlier.  OS X uses GCC, so it requires no special support.

    o Added MinGW detection in platform.h.
    
    o If you pass a flag (-X) to the examples that take the standard
      parameters (resetdb, simple1, etc.), it prints a usage message.
    
    o Better error handling in resetdb example, where errors are the
      most critical.  (If that one runs without errors, the others
      probably will, too, and you have to run that one first.)

    o resetdb now reports success, rather than succeeding silently.

    o Removed the code in sample1 example that duplicated util module's
      print_stock_table(), and called that function instead.

    o Moved the preview() calls in the example programs to before the
      query execution calls, because execution modifies the query.

    o All examples that take the standard command line parameters now 
      exit when connect_to_db() fails in one of the ways that don't
      throw an exception, rather than bulling onward until the next
      MySQL database call fails because the connection isn't up.

    o dbinfo example now takes the standard command line parameters.

    o Much better output formatting in dbinfo example.

    o Calling reset() where appropriate in the various example programs.
      Before, the programs may have worked, but not for the right
      reason.  This lead some people to believe that calling reset()
      was not necessary.

    o Fixed an incorrect use of row["string"] in complic1 example.

    o Lots of code style improvements to the examples.

    o Some VC++ type warnings squished.  Some remain.
    

1.7.22, 2004.11.17 (r302)

    o Applied patches by Zahroof Mohammed to allow it to build under GCC
      3.4.2.  Tested on MinGW and Fedora Core 3 systems.

    o Removed all the forward declarations in defs.h, and added
      forward declarations where necessary in individual header files.
      #including defs.h in fewer locations as a result.

    o Legacy headers sqlplus.hh and mysql++.hh now declare they are
      using namespace mysqlpp, to allow old code to compile against the
      new library without changes.

    o Removed query_reset parameter from several class Query member
      functions.  In the implementation, these parameters were always
      overridden!  No sense pretending that we pay attention to these
      parameters.  This changes the ABI version to 3.

    o #including custom.h in sql_query.h again...it's necessary on GCC
      3.4.
    
    o bootstrap script runs lib/config.pl after configure.  This is
      just a nicety for those running in 'maintainer mode'.


1.7.21, 2004.11.05 (r273)

    o Generating a main mysql++ RPM containing just the library files
      and basic documentation, and the -devel package containing
      everything else.

    o Devel package contains examples now, along with a new Makefile
      that uses the system include and library files, rather than the
      automake-based Makefile.am we currently have which uses the files
      in the mysql++ source directory.

    o Renamed sqlplusint subdirectory in the package to lib.

    o Removed the obsolete lib/README file.

    o lib/sql_query.h no longer #includes custom.h, simplifying
      build-time dependencies and shortening compile times.


1.7.20, 2004.11.03 (r258)

    o Collapsed all numbered *.hh headers into a single *.h file.  For
      example, the contents of row1.hh, row2.hh and row3.hh are now in
      row.h.

    o While doing the previous change, broke several circular
      dependencies.  (The numbered file scheme was probably partly done
      to avoid this problem.)  The practical upshot of most of these
      changes is that some functions are no longer inline.

    o Removed define_short.hh and everything associated with it.  The
      library now uses the short names exclusively (e.g. Row instead of
      MysqlRow).

    o Put all definitions into namespace mysqlpp.  For most programs,
      simply adding a 'using namespace mysqlpp' near the top of the
      program will suffice to convert to this version.

    o Once again, the main include file was renamed, this time to
      mysql++.h.  Hopefully this is the last renaming!

    o mysql++.hh still exists.  It emits a compiler warning that the
      file is obsolete, then it #includes mysql++.h for you.

    o sqlplus.hh is back, being a copy of the new mysql++.hh.  Both of
      these files may go away at any time.  They exist simply to help
      people transition to the new file naming scheme.

    o Renamed mysql++-windows.hh to platform.h, and added code to it to
      handle #inclusion of config.h on autotools-based systems
      intelligently.  This fixes the config.h error when building under
      Visual C++.

    o There is now only one place where conditional inclusion of
      winsock.h happens: platform.h.

    o Beautified the example programs.


1.7.19, 2004.10.25 (r186)

    o Fixed an infinite loop in the query mechanism resulting from the
      strstream change in the previous version.  There is an overloaded
      set of str() member functions that weren't a problem when query
      objects were based on strstream.
     
    o Query mechanism had a bunch of const-incorrectness: there were
      several function parameters and functions that were const for
      the convenience of other parts of the code, but within these
      functions the constness was const_cast away!  This was evil
      and wrong; now there are fewer const promises, and only one is
      still quietly broken within the code.  (It's in the SQLQuery
      copy ctor implementation; it should be harmless.)

    o Removed operator=() in Query and SQLQuery classes.  It cannot take
      a const argument for the same reason we have to cast away const
      in the SQLQuery copy ctor.  It's tolerable to do this in the copy
      ctor, but intolerable in an operator.  Since the copy ctor is good
      enough for all code within the library and within my own code, I'm
      removing the operator.

    o Above changes required bumping the ABI to version 2.

    o Visual C++ projects now look for MySQL build files in c:\mysql,
      since that's the default install location.  (Previously, it was
      c:\program files\mysql.)


1.7.18, 2004.10.01 (r177)

    o Changed all the strstream (and friends) stuff to stringstream type
      classes.  Let there be much rejoicing.

    o Query object now lets you use store() even when the SQL query
      cannot return a result, such as a DROP TABLE command.  This is
      useful for sending arbitrary SQL to the server.  Thanks to
      Jose Mortensen for the patch.

    o Quote fix in configure.in, thanks to David Sward.

    o Renamed undef_short file to undef_short.hh.

    o Gentoo ebuild file is actually being shipped with the tarball,
      instead of just sitting in my private CVS tree since 1.7.14 was
      current.  Ooops....


1.7.17, 2004.09.16 (r170)

    o Reverted one of the VC++ warning fix changes from 1.7.16 that
      caused crashes on Linux.

    o Added a configure test that conditionally adds the extra 'level'
      parameter to mysql_shutdown() that was added in MySQL 4.1.3 and
      5.0.1.


1.7.16, 2004.09.13 (r160)

    o Building VC++ version with DLL version of C runtime libraries, and
      at warning level 3 with no warnings emitted.

    o VC++ build no longer attempts to fake "long long" support.  See
      the Wishlist for further thoughts on this.


1.7.15, 2004.09.02 (r144)

    o Renamed Configure file to common.am, to avoid file name conflict
      with configure script on case-sensitive file systems.

    o Added ebuild file and ebuild target to top-level Makefile for
      Gentoo systems.  Thanks to Chris Frey for this.

    o Small efficiency improvements to BadQuery exception handling.
      Initial idea by Chris Frey, improvements by Warren Young.


1.7.14, 2004.08.26 (r130)

    o Builds with Visual C++ 7.1.

    o Fixed a bug in custom macro generation that caused problems with
      GCC 3.4.  (X_cus_value_list ctor definition was broken.)


1.7.13, 2004.08.23 (r92)

    o Removed USL CC support.  (System V stock system compiler.)  Use
      GCC on these platforms instead.

    o Added examples/README, explaining how to use the examples, and
      what they all do.

    o Most of the example programs now accept command line arguments for
      host name, user name and password, like resetdb does.

    o Renamed sinisa_ex example to dbinfo.

    o Several Standard C++ syntax fixes to quash errors emitted by
      GCC 3.4 and Borland C++ Builder 6.  Thanks to Steffen Schumacher
      and Totte Karlsson for their testing and help with these.

    o Added proper #includes for BCBuilder, plus project files for same.
      Thanks to Totte Karlsson for these.


1.7.12, 2004.08.19 (r63)

    o Many Standard C++ fixes, most from the GCC 3.4 patch by
      Rune Kleveland.

    o Added Wishlist file to distribution.

    o Fixed a problem in the bootstrap script that caused complaints
      from the autotools on some systems.

    o RPM building is working properly now.

    o Fixed the idempotency guard in datetime1.hh.


1.7.11, 2004.08.17 (r50)

    o Renamed mysql++, defs and define_short files, adding .hh to the
      end of each.  (They're header files!)  This shouldn't impact
      library users, since these are hopefully used internal to the
      library only.

    o Removed sqlplus.hh file.  Use mysql++.hh instead.
    
    o Added mysql++.spec, extracted from contributed 1.7.9 source RPM, 
      and updated it significantly.  Also, added an 'rpm' target to
      Makefile.am to automate the process of building RPMs.

    o Added bootstrap and LGPL files to distribution tarball.

    o Added pre-1.7.10 history to this file.

    o Removed .version file.  Apparently it's something required by old
      versions of libtool.


1.7.10, 2004.08.16 (r27)

    o Maintenance taken over by Warren Young (mysqlpp at etr dash usa
      dot com.) See http://lists.mysql.com/plusplus/3326 for details.

    o Applied many of the GCC 3.x patches submitted for 1.7.9 over
      the years.  This allows it to build on everything from 3.0 to
      3.3.3, at least.  Because so many patches are rolled up in one
      big jump, it's difficult to describe all the changes and where
      they came from.  Mostly they're Standard C++ fixes, as GCC
      has become more strict in the source code that it will accept.

    o MysqlRow used to overload operator[] for string types as well as
      integers so you could look up a field by its name, rather than by
      its index.  GCC 3.3 says this is illegal C++ due to ambiguities in
      resolving which overload should be used in various situations.
      operator[] is now overloaded only for one integer type, and a
      new member function lookup_by_name() was added to maintain the old
      by-field-name functionality.

    o Fixed another operator overloading problem in SSQLS macro
      generation with GCC 3.3.

    o The _table member of SSQLS-defined structures is now const char*,
      so you can assign to it from a const char* string.

    o Got autoconf/automake build system working with current versions
      of those tools again.  Removed the generated autotools files from
      CVS.

    o Renamed library file from libsqlplus to libmysqlpp.


1.7.9 (May 1 2001) Sinisa Milivojevic <sinisa@mysql.com>

    * Fixed a serious bug in Connection constructor when reading MySQL
    * options
    * Improved copy constructor and some other methods in Result /
    * ResUse
    * Many other minor improvements
    * Produced a complete manual with chapter 5 included
    * Updated documentation, including a Postscript format

1.7.8 (November 14 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * Introduced a new, standard way of dealing with C++ exceptions.
    * MySQL++ now supports two different methods of tracing exceptions.
    * One is by the fixed type (the old one) and one is standard C++
    * type by the usage of what() method. A choice of methods has to be
    * done in building a library. If configure script is run with
    * -enable-exception option , then new method will be used. If no
    * option is provided, or -disable-exception is used, old MySQL++
    * exceptions will be enforced. This innovation is a contribution of
    * Mr. Ben Johnson <ben@blarg.net>
    * MySQL++ now automatically reads at connection all standard MySQL
    * configuration files
    * Fixed a bug in sql_query::parse to enable it to parse more then 99
    * char's
    * Added an optional client flag in connect, which will enable usage
    * of this option, e.g. for getting matched and not just affected
    * rows. This change does not require any changes in existing
    * programs
    * Fixed some smaller bugs
    * Added better handling of NULL's. Programmers will get a NULL
    * string in result set and should use is_null() method in ColData to
    * check if value is NULL
    * Further improved configuration
    * Updated documentation, including a Postscript format

1.7.6 (September 22 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This release contains some C++ coherency improvements and scripts
    * enhacements
    * result_id() is made available to programmers to fetch
    * LAST_INSERT_ID() value
    * Connection constroctur ambiguity resolved, thanks to marc@mit.edu
    * Improved cnnfigure for better finding out MySQL libraries and
    * includes
    * Updated documentation, including a Postscript format

1.7.5 (July 30 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This release has mainl bug fixes  and code improvements
    * A bug in FieldNames::init has been fixed, enabling a bug free
    * usage of this class with in what ever a mixture of cases that is
    * required
    * Changed behaviour of ResUse, Result and Row classes, so that they
    * could be re-used as much as necessary, without any memory leaks,
    * nor with any re-initializations necessary
    * Fixed all potential leaks that could have been caused by usage of
    * delete instead of delete[] after memory has been allocated with
    * new[]
    * Deleted all unused classes and macros. This led to a reduction of
    * library size to one half of the original size. This has
    * furthermore brought improvements in compilation speed
    * Moved all string manipulation from system libraries to
    * libmysqlclient, thus enabling uniformity of code and usage of 64
    * bit integers on all platforms, including Windows, without
    * reverting to conditional compilation. This changes now requires
    * usage of mysql 3.23 client libraries, as mandatory
    * Changed examples to reflect above changes
    * Configuration scripts have been largely changed and further
    * changes shall appear in consecutive sub-releases. This changes
    * have been done and shall be done by our MySQL developer Thimble
    * Smith <tim@mysql.com>
    * Changed README, TODO and text version of manual. Other versions of
    * manual have not been updated
    * Fixed .version ``bug''. This is only partially fixed and version
    * remains 1.7.0 due to some problems in current versions of libtool.
    * This shall be finally fixed in a near future
    * Several smaller fixes and improvements
    * Added build.sh script to point to the correct procedure of
    * building of this library. Edit it to add configure options of your
    * choice

1.7 (May17 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This is mainly a release dealing with bug fixes, consistency
    * improvements and easier configure on some platforms
    * A bug in fetch_row() method of ResUse class has been fixed. Beside
    * changes that existed in a distributed patch, some additional error
    * checking has been introduced
    * A bug in escape manipulator has been fixed that could cause an
    * error if all characters had to be escaped
    * An inconsistency in column indexing has been fixed. Before this
    * version, column names in row indexing with strings, i.e.
    * row[<string>] , has been case sensitive, which was inconsistent
    * with MySQL server handling of column names
    * An inconsistency in conversion from strings to integers or floats
    * has been fixed. In prior version a space found in data would cause
    * a BadConversion exception. This has been fixed, but 100%
    * consistency with MySQL server has not been targeted, so that other
    * non-numeric characters in data will still cause BadConversion
    * exception or error. As this API is used in applications, users
    * should provide feedback if full compatibility with MySQL server is
    * desired, in which case BadConversion exception or error would be
    * abolished in some of future versions
    * A new method in ColData class has been introduced. is_null()
    * method returns a boolean to denote if a column in a row is NULL.
    * Finally, as of this release, testing for NULL values is possible.
    * Those are columns with empty strings for which is_null() returns
    * true.
    * Some SPARC Solaris installations had C++ exception problems with
    * g++ 2.95.2 This was a bug that was fixed in GNU gcc, as from
    * release 2.95 19990728. This version was thoroughly tested and is
    * fully functional on SPARC Solaris 2.6 with the above version of
    * gcc.
    * A 'virtual destructor ' warning for Result class has been fixed
    * Several new functions for STL strings have been added. Those
    * functions (see string_util.hh) add some of the functionality
    * missing in existing STL libraries
    * Conversion for 64 bit integers on FreeBSD systems has been added.
    * On those systems _FIX_FOR_BSD_ should be defined in CXXFLAGS prior
    * to configuring. Complete conversion to the usage of functions for
    * integer conversion found in mysqlclient library is planned for one
    * of the next releases
    * A completely new, fully dynamic, dramatic and fully mutable result
    * set has been designed and will be implemented in some of 2.x
    * releases
    * Several smaller fixes and improvements, including defaulting
    * exceptions to true, instead of false, as of this version
    * An up-to-date and complete Postscript version of documentation is
    * included in this distribution
    * Large chunks of this manual are changed, as well as README and
    * TODO files.

1.6 (Feb 3 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This is a major release as it includes new features and major
    * rewrites
    * Automatic quoting and escaping with streams. It works
    * automatically , depending on the column type. It will work with <<
    * on all ostream derived types. it is paricularly handy with query
    * objects and strstreams. Automatic quoting and escaping on cout,
    * cerr and clog stream objects is intentionally left out, as quoting
    * / escaping on those stream objects is not necessary. This feature
    * can be turned of by setting global boolean dont_quote_auto to
    * true.
    * Made some major changes in code, so that now execute method should
    * be used only with SSQL and template queries, while for all other
    * query execution of UPDATE's, INSERT's, DELETE's, new method exec()
    * should be used. It is also faster.
    * New method get_string is inroduced for easier handling / casting
    * ColData into C++ strings.
    * Major rewrite of entire code, which led to it's reduction and
    * speed improvement. This also led to removal of several source
    * files.
    * Handling of binary data is introduced. No application program
    * changes are required. One of new example programs demonstrates
    * handling of binary data
    * Three new example programs have been written and thoroughly
    * tested. Their intention is to solve some problems addressed by
    * MySQL users.
    * Thorough changes is Makefile system has been made
    * Better configuration scripts are written, thanks to D.Hawkins
    * <dhawkins@cdrgts.com>
    * Added several bug fixes
    * Changed Manual and Changelog

    * UnixWare 7.0 compiler

.64.1.1a (Sep 27 1998)

    * Fixed several bugs that caused my library to fail to compile with
    * egcs 1.1. Hopefully it will still compile with egcs 1.0 however I
    * have not been able to test it with egcs 1.0.
    * Removed some problem causing debug output in sql++pretty.

.64.1a (Aug 1 1998)

    * Added an (almost) full guide to using Template Queries.
    * Fixed it so the SQLQuery will throw an exception when all the
    * template parameters are not provided.
    * Proofread and speedchecked the manual (it really needed it).

    * there corresponding constructors.
    * Added methods for creating a mysql_type_info from a C++ type_info.

.64.a (July 24 1998)

    * Changed the names of all the classes so they no longer have to
    * have Mysql in the begging of it. However if this creates a problem
    * you can define a macro to only use the old names instead.
    * The Specialized SQL Structures (formally known as Custom Mysql
    * Structures) changed from mysql_ to sql_.
    * Added the option of using exceptions thoughout the API.
    * ColData (formally known as MysqlStrings) will now throw an
    * exception if there is a problem in the conversion.
    * Added a null adapter.
    * Added Mutable Result Sets
    * Added a very basic runtime type identification for SQL types
    * Changed the document format from POD to LYX .
    * Am now using a modified version of Perceps to extract the class
    * information directly from the code to make my life easier.
    * Added an option of defining a macro to avoid using the automatic
    * conversion with binary operators.
    * Other small fixed I probully forgot to mentune.

    * Added Template Queries
    * Created s separate SQLQuery object that is independent of an SQL
    * connection.
    * You no longer have to import the data for the test program as the
    * program creates the database and tables it needs.
    * Many small bug fixes.

.61.1.a (April 28 1998)

    * Cleaned up the example code in test.cc and included it in the
    * manual.
    * Added an interface layout plan to the manual.
    * Added a reverse iterator.
    * Fixed a bug with row.hh (It wasn't being included because of a
    * typo).

.61.0.a

    * Major interface changes. I warned you that the interface may
    * change while it is in pre-alpha state and I wasn't kidding.
    * Created a new and Separate Query Object. You can no longer execute
    * queries from the Mysql object instead you have to create a query
    * object with Mysql::query() and use it to execute queries.
    * Added the comparison operators to MysqlDate, MysqlTime and
    * MysqlDateTime. Fixed a few bugs in the MysqlDate... that effected
    * the stream output and the conversion of them to strings.
    * Reflected the MysqlDate... changes in the manual.
    * Added a new MysqlSet object and a bunch of functions for working
    * with mysql set strings.

.60.3a (April 24 1998)

    * compatibility Minor Manual fix.
    * Changed makefile to make it more compatible with Solaris (Thanks
    * Chris H)
    * Fixed bug in comparison functions so that they would compare in he
    * right direction.
    * Added some items to the to do list be sure to have a look.

What It Is
~~~~~~~~~~
    MySQL++ is a C++ wrapper for MySQL's C API.  It is built around STL
    principles, to make dealing with the database as easy as dealing

    with an STL container.  MySQL++ relieves the programmer of dealing
    with cumbersome C data structures, generation of repetitive SQL
    statements, and manual creation of C++ data structures to mirror
    the database schema.




    Its home page is http://tangentsoft.net/mysql++/
















Prerequisites
~~~~~~~~~~~~~
    To build MySQL++, you must have the MySQL C API development
    files installed.







    On Unixy systems (Linux, Mac OS X, Cygwin, *BSD, Solaris...),
    the MySQL development files are installed if you build MySQL
    from source.  If you installed MySQL as a binary package, then





    the development files are often packaged separately from the
    MySQL server itself.  It's common for the package containing the
    development files to be called something like "MySQL-devel".


    If you're building on Windows with Visual C++ or MinGW, you
    need to install the native Win32 port of MySQL from mysql.com.
    The development files are only included with the "complete"
    version of the MySQL installer, and some versions of this
    installer won't actually install them unless you do a custom
    install.  Another pitfall is that MySQL++'s project files assume
    that you've installed the current General Availability release of
    MySQL (v5.0 right now) and it's installed in the default location.
    If you've installed a different version, or if MySQL Inc. changes
    the default location (which they seem to do regularly!) you'll have
    to adjust the link and include file paths in the project settings.





Additional Things to Read






































~~~~~~~~~~~~~~~~~~~~~~~~~
    Each major platform we support has a dedicated README-*.txt
    file for it containing information specific to that platform.
    Please read it.





    For authorship information, see the CREDITS.txt file.





    For license information, see the COPYING.txt file.



    If you want to change MySQL++, see the HACKERS.txt file.



    You should have received a user manual and a reference manual
    with MySQL++.  If not, you can read a recent version online:





        http://tangentsoft.net/mysql++/doc/



    Search the MySQL++ mailing list archives if you have more
    questions:



        http://lists.mysql.com/plusplus/






Building the Library
~~~~~~~~~~~~~~~~~~~~
    MySQL++ uses Bakefile (http://bakefile.org/) to generate
    platform-specific project files and makefiles from a single set
    of input files.  We currently support these build systems:


    autoconf:
        For Unixy platforms, including Linux, Mac OS X, and Cygwin, in
        addition to the "real" Unices.  See README-Unix.txt for general
        instructions.  Supplementary platform-specific details are
        in README-Cygwin.txt, README-Linux.txt, README-Mac-OS-X.txt,
        and README-Solaris.txt.


    MinGW:
        We ship Makefile.mingw for MinGW.  It currently only builds the
        static version of the library for technical reasons.  This has
        licensing ramifications.  See README-MinGW.txt for details.


    Visual C++:
        We ship Visual Studio 2003, 2005, and 2008 project files.
        No older version of Visual C++ will build MySQL++, due to
        compiler limitations.  See README-Visual-C++.txt for more
        details.




    Xcode:
        We ship an Xcode v2 project file.  It hasn't been tested
        much yet, since the autoconf method works just fine on OS X.
        As a result, we need both success and failure reports on the
        mailing list.  See README-Mac-OS-X.txt for more information.





Example Programs

~~~~~~~~~~~~~~~~
    You may want to try out the programs in the examples subdirectory
    to ensure that the MySQL++ API and your MySQL database are both
    working properly.  Also, these examples give many examples of
    the proper use of MySQL++.  See README-examples.txt for further
    details.









Unsupported Compliers
~~~~~~~~~~~~~~~~~~~~~
    If you're on Windows but want to use some other compiler besides
    Visual C++ or GCC, you are currently on your own.  There have
    been past efforts to port MySQL++ to other Windows compilers,
    but for one reason or another, all of these ports have died.



    On Unixy systems, GCC still works best.  "Native" compilers and
    third-party compilers may work, but you're on your own to get
    it working.









    We have nothing in particular against these unsupported systems.
    We just lack the time and resources to support everything
    ourselves.  If you are sufficiently motivated to get MySQL++
    working on one of these alternate systems, see the HACKERS.txt
    file first for guidance.  If you follow the advice in that file,
    your patch will be more likely to be accepted.

Visual C++ Version Compatibility
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    MySQL++ is fully functional with Visual C++ 2005 and 2008.


    MySQL++ also works with VC++ 2003 (a.k.a. VC++ 7.1), with the
    exception of the SSQLS feature.  There was partial support for
    SSQLS with VC++ 2003 in MySQL++ v2, but a feature we added in
    MySQL++ v3.0 crashes this version of the compiler, so we had to
    remove support for it entirely.  MySQL++ automatically disables
    SSQLS when you build it with VC++ 2003.  As long as you avoid
    using that feature of the library, you should be fine.


    Older versions of Visual C++ are basically hopeless when it
    comes to building current versions of MySQL++.  They have too
    many weaknesses in their Standard C++ implementation to build a
    modern library like MySQL++.  If you cannot upgrade your compiler,
    my advice is that you're best off programming straight to the
    MySQL C API rather than try to make MySQL++ build.

    There are two sets of .sln and .vcproj files shipped with MySQL++:
    one for Visual C++ 2003 in the vc2003 subdirectory, and another
    set for VC++ 2005 and newer in vc2005.  The only difference
    between them is that the VC++ 2003 versions omit SSQLS related
    files from the build.  If you're using VC++ 2008, use the vc2005
    project files; Visual Studio will walk you through the conversion
    process, which will do the right thing.


Prerequisites
~~~~~~~~~~~~~


    You need to have the Windows version of the MySQL server installed
    on your development system, even if you always access a MySQL
    server on a different machine.  This is because in addition to
    installing the server itself, the official MySQL Windows binaries
    also install the client-side development files that MySQL++
    needs in order to communicate with a MySQL server.




    You have to do a Custom install to enable installation of these
    development files.  If you get an error about mysql-version.h or
    mysql.h when building MySQL++, go back and reinstall the MySQL
    server, paying careful attention to the options.

    If you've installed the development files and are still getting


    header file include errors, read on.













Building the Library and Example Programs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    If you installed the MySQL server somewhere other than 
    

        C:\Program Files\MySQL\MySQL Server 5.0\
        
    you need to change the project file settings.  If you're willing to
    install Bakefile (see below), you can do this quickly by changing
    the variable MYSQL_WIN_DIR at the top of the file mysql++.bkl,
    then regenerating the project files by running rebake.bat.
    Otherwise, you'll need to change the include and library paths
    in all of the project files by hand.

    You must build both the Debug and Release versions of the library,
    because a release build of your program won't work with a Debug
    version of the MySQL++ DLL.  Since version 3.0, the VC++ build
    of MySQL++ names these two DLLs differently: mysqlpp_d.dll for
    the Debug version, and mysqlpp.dll for the Release version.
    This lets you keep them in the same PATH directory, without a
    concern as to whether the correct one will be used.

    With the library built, run at least the resetdb and simple1
    examples to ensure that the library is working correctly.
    In addition to the other generic examples, there are a few
    Visual C++ specific examples that you might want to look at in
    examples\vstudio.  See README-examples.txt for further details.

    Once you're sure the library is working correctly, you can run
    the install.hta file at the project root to install the library
    files and headers in a directory of your choosing.
    
    (Aside: You may not have come across the .hta extension before.
    It's for a rarely-used feature of Microsoft's Internet Explorer,
    called HTML Applications.  Know what Adobe AIR is?  Kinda like
    that, only without the compilation into a single binary blob,
    the cross-platform compatibility, and the power of Flash and
    ActionScript 3.  These limitations don't cause a problem here.
    In fact, AIR would be vast overkill here.  Just open install.hta
    in a text editor to see how it works.)


Using MySQL++ in an MFC Project
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



    If you don't already have a project set up, open Visual Studio,
    say File > New > Project, then choose Visual C++ > MFC > MFC
    Application.  Go through the wizard setting up the project as
    you see fit.


    Once you have your project open, right click on your top-level
    executable in the Solution Explorer, choose Properties, and make
    the following changes.  (Where it doesn't specify Debug or Release,
    make the same change to both configurations.)


        o Append the following to C/C++ > General > Additional Include
          Directories:


            C:\Program Files\MySQL\MySQL Server 5.0\include,
            C:\mysql++\include



        o Under C/C++ > Code Generation change "Runtime Library" to
          "Multi-threaded Debug DLL (/MDd)" for the Debug
          configuration.  For the Release configuration, make it
          "Multi-threaded DLL (/MD)".


        o Append the following to Linker > General > Additional Library
          Directories for the Debug configuration:



            C:\Program Files\MySQL\MySQL Server 5.0\lib\debug,
            C:\mysql++\vc\debug


          For the Release configuration, make it the same, but
          change the 'debug' directory names to 'opt'.

        o Under Linker > Input add the following to "Additional
          Dependencies" for the Debug configuration:






            libmysql.lib wsock32.lib mysqlpp_d.lib







          ...and then for the Release configuration:
          




            libmysql.lib wsock32.lib mysqlpp.lib






          This difference is because MySQL++'s Debug DLL and import
          library have a _d suffix so you can have both in the same
          directory without conflicts.






    You may want to study examples\vstudio\mfc\mfc.vcproj to see
    this in action.  Note that some of the paths will be different,
    because it can use relative paths for mysqlpp.dll.



Using MySQL++ in a Windows Forms C++/CLI Project
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~





    Before you start work on getting MySQL++ working with your own
    program, you need to make some changes to the MySQL++ build
    settings.  Open mysqlpp.sln, then right-click on the mysqlpp
    target and select Properties.  Make the following changes for
    both the Debug and Release configurations:

        o Under Configuration Properties > General, change "Common
          Language Runtime support" to the /clr setting.







        o Under C/C++ > Code Generation, change "Enable C++ Exceptions"
          from "Yes (/EHsc)" to "Yes With SEH Exceptions (/EHa)"




    If you have already built MySQL++, be sure to perform a complete
    rebuild after changing these options.  The compiler will emit
    several C4835 warnings after making those changes, which are
    harmless when using the DLL with a C++/CLI program, but which
    warn of real problems when using it with unmanaged C++.  This is
    why MySQL++'s Windows installer (install.hta) offers the option
    to install the CLR version into a separate directory; use it if
    you need both managed and unmanaged versions installed!







    For the same reason, you might give some thought about where you
    install mysqlpp.dll on your end user's machines when distributing
    your program.  My recommendation is to install it in the same
    directory as the .exe file that uses it, rather than installing
    into a system directory where it could conflict with a mysqlpp.dll
    built with different settings.

    Once you have MySQL++ built with CLR support, open your program's
    project.  If you don't already have a project set up, open Visual
    Studio, say File > New > Project, then choose Visual C++ > CLR >
    Windows Forms Application.  Go through the wizard setting up the
    project as you see fit.

    The configuration process isn't much different from that for an
    MFC project, so go through the list above first.  Then, make the
    following changes particular to .NET and C++/CLI:

        o Under Configuration Properties > General change the setting
          from /clr:pure to /clr.  (You need mixed assembly support
          to allow a C++/CLI program to use a plain C++ library
          like MySQL++.)

        o For the Linker > Input settings, you don't need wsock32.lib.
          The mere fact that you're using .NET takes care of that
          dependency for you.

    In the MFC instructions above, it said that you need to build it
    using the Multi-threaded DLL version of the C++ Runtime Library.
    That's not strictly true for MFC, but it's an absolute requirement
    for C++/CLI.  See the Remarks in this MSDN article for details:

        http://msdn2.microsoft.com/en-us/library/k8d11d4s.aspx

    You may want to study examples\vstudio\wforms\wforms.vcproj to
    see all this in action.  Note that some of the paths will be
    different, because it can use relative paths for mysqlpp_d.dll
    and mysqlpp.dll.


Working With Bakefile
~~~~~~~~~~~~~~~~~~~~~


    MySQL++'s top-level Visual Studio project files aren't
    maintained directly.  Instead, we use a tool called Bakefile
    (http://bakefile.org/) to generate many different project file
    and Makefile types from a single set of source files.  There is
    a native Windows version of Bakefile up on that web site.
    Download that and put the directory containing bakefile_gen.exe
    in your Windows PATH.


    Bakefile generates the various project files and Makefiles from
    a single source file, mysql++.bkl.  This is usually the file you
    need to change when you want to make some change to the MySQL++
    build system.



    While Bakefile's documentation isn't as comprehensive as it
    ought to be, you can at least count on it to list all of the
    available features.  So, if you can't see a way to make Bakefile
    do something, it's likely it just can't do it.  Bakefile is a
    high-level abstraction of build systems in general, so it'll never
    support all the particulars of every odd build system out there.

    Once you've made your changes, you can generate the Visual C++
    project files by running rebake.bat, which you can find in the
    same directory as this file.


If You Run Into Problems...
~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Especially if you have linking problems, make sure your project
    settings match the above.  Visual C++ is very picky about things
    like run time library settings.  When in doubt, try running one
    of the example programs.  If it works, the problem is likely in
    your project settings, not in MySQL++.

:no_perl


echo.
echo You need a Perl interpreter installed on your system, somewhere in

echo any special extensions.  The easiest to install on Windows would be
echo ActivePerl, from http://activestate.com/Products/activeperl/

echo If you're familiar with Unix, you might like Cygwin better instead:
echo http://cygwin.com/setup.exe
echo.

cd ..

:no_mysqlpp_h
echo.
echo WARNING: Can't make lib/mysql++.h

echo.
echo On Unixy systems, autoconf creates lib/mysql++.h from lib/mysql++.h.in
echo but there is no easy way to do this on Windows.  You can do it manually:
echo just copy the file to the new name, and edit the MYSQLPP_HEADER_VERSION
echo definition to put the proper version number parts into the macro.  It
echo needs to look something like this:
echo.

echo #define MYSQLPP_HEADER_VERSION MYSQLPP_VERSION(3, 0, 0)
echo.
echo It's important that the three numbers match the actual library version
echo number, or else programs that check this (like resetdb) will fail.
echo.
echo Alternately, if you've also got MySQL++ installed on some Unixy type
echo system, you can let its bootstrap procedure create mysql++.h and then
echo copy it to the Windows machine.
echo.

#
# SYNOPSIS
#
#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION


#
#   This macro figures out how to build C programs using POSIX threads. It
#   sets the PTHREAD_LIBS output variable to the threads library and linker
#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
#   flags that are needed. (The user can also force certain compiler
#   flags/libs to be tested by setting these environment variables.)
#

#   Also sets PTHREAD_CC to any special C compiler that is needed for
#   multi-threaded programs (defaults to the value of CC otherwise). (This

#   is necessary on AIX to use the special cc_r compiler alias.)

#
#   NOTE: You are assumed to not only compile your program with these flags,
#   but also link it with them as well. e.g. you should link with
#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
#   If you are only building threads programs, you may wish to use these
#   variables in your default LIBS, CFLAGS, and CC:
#
#          LIBS="$PTHREAD_LIBS $LIBS"
#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
#          CC="$PTHREAD_CC"
#



#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
#   is not found. If ACTION-IF-FOUND is not specified, the default action
#   will define HAVE_PTHREAD.

#





#   Please let the authors know if this macro fails on any platform, or if
#   you have any other suggestions or comments. This macro was based on work
#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
#   grateful for the helpful feedback of numerous users.

# -kthread: FreeBSD kernel threads (preferred to -pthread since SMP-able)
# lthread: LinuxThreads port on FreeBSD (also preferred to -pthread)
# -pthread: Linux/gcc (kernel threads), BSD/gcc (userland threads)
# -pthreads: Solaris/gcc
# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
#      doesn't hurt to check since this sometimes defines pthreads too;
#      also defines -D_REENTRANT)
#      ... -mt is also the pthreads flag for HP/aCC
# pthread: Linux, etcetera
# --thread-safe: KAI C++

dnl @synopsis MYSQLPP_DEVEL
dnl 
dnl This macro tries to find the MySQL++ library and header files.
dnl
dnl We define the following configure script flags:
dnl
dnl		--with-mysqlpp: Give prefix for both library and headers, and try
dnl			to guess subdirectory names for each.  (e.g. tack /lib and
dnl			/include onto given dir name, and other common schemes.)
dnl		--with-mysqlpp-lib: Similar to --with-mysqlpp, but for library only.
dnl		--with-mysqlpp-include: Similar to --with-mysqlpp, but for headers
dnl			only.
dnl
dnl This macro depends on having the default compiler and linker flags
dnl set up for building programs against the MySQL C API.  The mysql.m4
dnl macro in this directory fits this bill; run it first.

/// Connection objects due to a hard limitation of the underlying
/// C API.  Connection pools are most useful in multithreaded programs,
/// but it can be helpful to have one in a single-threaded program as

/// requires multiple connections.  Whether you use a pool or manage
/// connections yourself is up to you, but realize that this class
/// takes care of a lot of subtle details for you that aren't obvious.
///
/// The pool's policy for connection reuse is to always return the 
/// \em most recently used connection that's not being used right now.
/// This ensures that excess connections don't hang around any longer
/// than they must.  If the pool were to return the \em least recently
/// used connection, it would be likely to result in a large pool of
/// sparsely used connections because we'd keep resetting the last-used

Prerequisite: Create Import Library

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
	Before you can build MySQL++ with MinGW, you will need to
	create a MinGW-compatible import library for MySQL's C API
	library.  Assuming you installed MySQL in c:\mysql and MySQL++
	in c\mysql++, the commands to do this are:



		mkdir c:\mysql\lib\opt
		cd c:\mysql\lib\opt
	    dlltool -k -d c:\mysql++\libmysqlclient.def -l libmysqlclient.a



Building the Library and Example Programs

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
	Now you can build MySQL++ with this command:

	
		mingw32-make -f Makefile.mingw

	Notice that we're using the MinGW-specific version of GNU
	make, not the Cygwin or MSYS versions.	This is in order to
	get proper path separator handling.

	If you didn't install MySQL in c:\mysql, it's probably simplest
	to just change the Makefile.mingw files.  Theoretically you
	could adjust the Bakefiles instead, but due to the way we're
	using Bakefile, it's a little difficult to rebuild Makefiles
	on Windows right now.

	If you want to change the install location, that is in
	install.bat.

dnl @synopsis LIB_SOCKET_NSL
dnl 
dnl This macro figures out what libraries are required on this platform
dnl to link sockets programs.
dnl
dnl The common cases are not to need any extra libraries, or to need
dnl -lsocket and -lnsl.  We need to avoid linking with libnsl unless
dnl we need it, though, since on some OSes where it isn't necessary it

dnl will totally break networking.  Unisys also includes gethostbyname()
dnl in libsocket but needs libnsl for socket().

The user manual is written in XML DocBook format, version 4.2. We
restrict ourselves to Simplified DocBook 1.1 as much as possible.
(Why these versions? They're the newest supported on the oldest system
I still use, Red Hat Linux 9.)

If you're looking to hack on the manual, here are some helpful resources
for getting up to speed on DocBook:


Mills' "Installing And Using An XML/SGML DocBook Editing Suite" article:

	http://supportweb.cs.bham.ac.uk/documentation/tutorials/docsystem/build/tutorials/docbooksys/docbooksys.html

	This is the best tutorial I've found.
	

Walsh and Muellner's _Simplified DocBook: The Definitive Guide_ book:

	http://www.docbook.org/tdg/simple/en/html/sdocbook.html

	This is the most accessible reference.


Walsh and Muellner's _DocBook: The Definitive Guide_ book, second
edition, online version:

	http://www.docbook.org/tdg/en/html/docbook.html

	This is the official DocBook referece; the "Simplified" guide is a
	subset of this book.


DocBook FAQ:

	http://www.dpawson.co.uk/docbook/

	Go here when you have a question that the tutorials and references
	do not answer.


xsltproc:

	http://xmlsoft.org/XSLT/

	This is the XSL processor that takes the DocBook file and an XSL
	stylesheet and produces either HTML or XSL+FO. (The latter is an
	intermediate step towards any of several print-oriented formats,
	such as PDF or TeX.) If your system has GNOME on it, you probably
	have this installed already.

	You will also need the standard set of DocBook style sheets.  On
	Red Hat Linux and Fedora Core, these are in the docbook-style-xsl
	package.


FOP:

	http://xml.apache.org/fop/

	This is the XSL+FO document processor we use to build the PDF
	files. ('make pdf')

	If for some reason you have trouble getting FOP working, there's
	an alternate method available as 'make oldpdf' which uses xsltproc
	and pdfxmltex. It produces a pretty ugly PDF, but you probaly
	already have the tools installed, if you have any of them at all.
	pdfxmltex is in the xmltex package on Fedora Core 3.

	If neither of those work for you, you could use the OpenJade
	tool chain instead. (http://openjade.org/) This is SGML DocBook
	rather than the more modern XML DocBook I favor, but the only
	XML-specific thing we are using is local XSL stylesheets. You
	could ignore them and use the standard DSSSL stylesheets
	instead. I avoid the SGML tool chain only because I've had
	trouble with it in the past.

mysql++-devel RPM installs the files you need when building your own
MySQL++ based programs, as well as documentation and examples that

can help you learn how to use the library.

The MySQL++ header files are in /usr/include/mysql++, the library
is in /usr/lib, and the example programs' source code is in
/usr/share/doc/mysql++-devel-*/examples.  For more information on

the examples, see the README-examples.txt file in the directory

3.0.1, 2008.03.19 (r2255)


    o String objects can now be compared to mysqlpp::null directly.

    o Added a template operator== and operator!= to String, syntactic
      sugar for the existing String::compare() methods.


    o String::compare() now returns 0 ("equal") when one of the
      strings is an uninitialized String() (no refcounted buffer)
      and the other is empty.  It used to consider any initialized
      string greater than an uninitted one.  An uninitialized String
      appears empty, though, so this was incorrect.

    o Made Connection::thread_aware(), thread_start() and thread_end()
      static methods, so they can be called before you create your
      first connection.  Ditto for DBDriver versions of these methods.

    o Calling Connection::thread_start() and thread_end() in
      examples/cpool.cpp, as appropriate.  Above changes were necessary
      to make this work sensibly.

    o Made ConnectionPool::release() virtual, so your pool subclass can
      override it.

    o Added ConnectionPool::size(), so a subclass can know the current
      number of extant connections.

    o No longer single-quoting NOW() call generated for default
      init of DateTime type when building queries from SSQLS objects
      in Query::insert(), replace() and update().  The template query
      and stream interfaces of Query treated NOW() correctly already.

    o Fixed a bug that left SSQLS::table_override_ uninitted if
      you used certain of the generated ctors or set() member
      functions instead of others used by the examples.  This could
      cause a crash any time you caused SSQLS.table() to be called,
      such as when passing the SSQLS to Query::insert().

    o Minor memset bug fixed in test/uds.cpp.  Patch by Dave Jones.


3.0.0, 2008.02.29 (r2236) The "Giant Leap Forward" release

    THIS IS NOT A DROP-IN REPLACEMENT FOR MySQL++ v2.x!

    You will have to recompile your program against this version
    of the library, and you will almost certainly have to make code
    changes as well.  Please see these sections in the user manual
    for information on migrating your code to this new version:

    http://tangentsoft.net/mysql++/doc/html/userman/breakages.html#api-3.0.0
    http://tangentsoft.net/mysql++/doc/html/userman/breakages.html#abi-3.0.0

    o Added ConnectionPool class, primarily to let multithreaded
      programs share a set of Connection objects safely in situations
      where it isn't acceptable to have a Connection per thread.

    o Created examples/cpool.cpp to demonstrate this new class.

    o Added RefCountedPointer template, which provides automatic
      memory management and data sharing.  It's not intended
      for use outside of MySQL++ itself, but it's the mechanism
      behind everything below where reference counting is mentioned.
      I created the initial version of it, but Jonathan Wakely almost
      completely rebuilt it, and Joseph Artsimovich provided helpful
      commentary and advice as well.

    o Many improvements to Specialized SQL Structures (SSQLS):

      - Renamed custom* to ssqls*.  There's still a custom.h which
        #includes ssqls.h for you, but it's only intended to ease
        the transition to the new name.  It will go away in a future
        release, probably as soon as v3.1.

      - SSQLSes are finally compatible with Null<>-wrapped types.  This
        feature is based loosely on the "Waba" patch posted to the
        mailing list back in the v2.0 days, but extended to allow
        Null<T> types for key fields.  (The Waba patch only allowed
        these types in non-key fields.)

      - It's no longer necessary to define a different SSQLS for each
        different field set you use in queries.  That is to say,
        you can define an SSQLS for an entire table and store just a
        subset of the table in it now, with the other fields keeping
        default values.  Removed examples/custom6.cpp, as custom1.cpp
        can now demonstrate the same thing, implicitly.

      - An SSQLS's field order no longer has to match the order of
        fields in the result set it is populated from.

      - As a result of previous, removed sql_create_c_order_* macros;
        they have no purpose now.

      - Removed order parameters from sql_create_complete_*, which now
        gives it the same functionality as sql_create_c_names_* so
        removed the latter, too.

      - Removed "basic" variants of SSQLS creation macros.  They've
        been unofficially deprecated by dint of being all but
        undocumented and unexemplified for a very long time now.

      - It's now possible to use mysqlpp::String, Date, DateTime, and
        Time types in the key field positions in an SSQLS as they
        now support the necessary comparison interfaces.

      - If you use a floating-point data type in one of the key field
        positions, it no longer uses exact comparison logic.  Instead,
        it now does [in]equality comparisons by testing whether the
        difference between two floating-point values is less than a
        configurable threshold defaulting to 0.00001.
    
      - You can now use 'bool' type in an SSQLS.

      - Renamed _table static member variable in each SSQLS to table_
        and made it private.  There are now public setter and getter
        methods, table().

      - Added per-instance table name overriding via instance_table()
        setter.  table() getter returns static version if this is not
        set, so it's still a global setting by default.

    o You can now use mysqlpp::null as a template query parameter to
      get a SQL null.

    o Replaced template ColData_Tmpl<T>:

      - Used to have typedef ColData_Tmpl<std::string> MutableColData.
        It was used only once within MySQL++ itself, and was never
        documented as a class for end users.  This one use within
        the library was a crock, so we just replaced this use with
        std::string and removed the typedef.

      - This left just one use of ColData_Tmpl<T>, instantiating it
        with the MySQL++ utility class const_string, basically a
        clone of std::string with all the mutating features removed.
        Folded the functionality of const_string into the template,
        renamed the result to String, and deleted the const_string
        class.  It'd be a complete std::string replacement -- with
        SQL-related enhancements -- if it were modifiable, but MySQL++
        doesn't need it to be modifiable.  Yet, it's still the closest
        thing MySQL++ has to its own string type; thus the name.

      - Replaced its internal buffer management with a much more
        clever reference counted scheme.  This shows its greatest
        advantage in the return from Row::operator[](), which for
        technical reasons must return by value, not by reference
        as is more common.  This lets you pass around Strings by
        value while having the efficiency of reference semantics.
        This can be important with large return values, like BLOBs.

      - Converting String to numeric types (ints, floats...) uses a
        new, cleaner system by Jonathan Wakely.  Unless you were
        abusing weaknesses in the old system, you won't see a
        difference.  It's just more robust and flexible.

    o Redesigned SQLString:

      - It used to derive from std::string, and while MySQL++'s
        internals did use it in place of std::string, these places
        didn't take advantage of the additional features offered
        by SQLString.  So, replaced all those uses with std::string.

      - All the remaining uses are MySQL++ public interfaces that
        need to be able to accept any of many different data types,
        and we want that data to be automatically converted to a
        SQL-compatible string form.  Because it no longer has the
        parentage to be a general-purpose string type and MySQL++ has
        a new contender for that role (String), renamed SQLString to
        SQLTypeAdapter to reflect its new, limited purpose.  ("STA"
        for short.)

      - Since we don't have the std::string base class to manage the
        string buffer any more, using the same reference counted
        buffer mechanism as String.  In addition to saving code by
        not creating yet another buffer management mechanism, it means
        objects of the two classes can share a buffer when you assign
        one to the other or pass one to the other's copy ctor.

      - Added many more conversion ctors.

      - STA interfaces using the 'char' data type now treat them as
        single-character strings instead of one-byte integers, as
        does the Standard C++ Library.

      - Added mysqlpp::tiny_int interfaces to STA to replace the
        former char interfaces for those needing one-byte integers.

    o As a result of the ColData -> String redesign, removed
      Row::raw_*().  Before String copies were efficient, this
      was helpful in accessing BLOB data efficiently.  It was also
      required back when ColData didn't deal correctly with embedded
      null characters, but that reason is gone now, too.

    o Row::operator[](const char*) no longer unconditionally throws the
      BadFieldName exception when you ask for a field that doesn't
      exist.  It will still throw it if exceptions are enabled, but if
      not, it'll just return an empty String.  This was necessary to
      make the SSQLS subset and field order independence features work.

    o Similarly, Result::field_num() returns -1 when exceptions are
      disabled and you ask for a field that doesn't exist.

    o You can now use the OptionalExceptions mechanism to disable
      exceptions on const MySQL++ objects.

    o Redesigned query result classes:

      - Instead of Result deriving from ResUse, the two derive from
        a common base class -- ResultBase -- containing the bits that
        are truly the same between them.  Before, Result inherited
        several methods that didn't really make sense for "store"
        query result sets.

      - Renamed Result to StoreQueryResult and ResUse to UseQueryResult
        so it's clearer what each is for.

      - Renamed ResNSel to SimpleResult.

      - Made all SimpleResult data members private and hid them behind
        const accessor functions of the same name.

      - The result set classes all used to be friends of Connection
        for various lame reasons.  Since they are created by Query,
        and Query has a good reason for a strong relationship with
        Connection, moved Connection access out of each result set
        class into the code in Query that creates that type of result
        set object.

      - StoreQueryResult now derives from vector<Row> in addition to
        ResultBase; it used to merely emulate a vector of Rows, poorly.
        It can now dispose of the MYSQL_RESULT at the end of object
        construction, because it creates all the Row objects up front
        instead of on the fly.  And as a result of *that*, operator[]
        returns by reference instead of by value, operator -> works
        correctly on iterators, all STL algorithms work, etc., etc.

      - IMPORTANT COMPATIBILITY BREAK: because we used fetch_row()
        stuff in Result previously, it was okay to index past the
        end of the result set: you'd just get a falsy Row when you
        did this, just as happens when doing the same thing in a
        "use" query.  The simple1 and simple2 examples did this,
        so it's likely that code exists that takes advantage of this
        misfeature.  New versions of these examples show how to index
        through a StoreQueryResult without running past its end.

      - ResUse used to delay creation of its FieldNames and FieldTypes
        objects until the point of need.  This had several implications
        for thread and exception safety that we fix by just creating
        them in the ctor.  If your code is multi-threaded and was
        avoiding certain usage patterns due to crashes, it's worth
        trying your preferred way again.

      - Result sets create a few data structures to hold information
        common to all rows in that set.  The row objects need access
        to these shared data structures, so on creation each gets
        a pointer back to the result set object that creates it.
        This was efficient, but required that a result set object
        outlive any row objects it creates.  Now these shared data
        structures are reference-counted, decoupling the lifetime of
        the child row objects from their result set parent.

      - Copy operations for result sets used to actually be "moves"
        before, for efficiency.  (MySQL++ itelf only copied result
        sets in returning them by value from the query execution
        methods of Query, so this was acceptable if you didn't do
        anything uncommon with these objects.)  Reference counted
        data structures allow us to have copy semantics now without
        sacrificing efficiency.

      - You can now use Query::storein() with an STL container of Row
        objects now, instead of having to use SSQLSes.  The lifetime
        issue guaranteed a crash if you tried this before.

      - Removed a bunch of unnecessary alias methods:

        - columns() -> num_fields()
        - names()   -> field_names()
        - rows()    -> num_rows()
        - types()   -> field_types()

      - Renamed several methods for grammar reasons:

        - fields(unsigned int)      -> field(unsigned int)
        - names(const std::string&) -> field_num(const std::string&)
        - names(int)                -> field_name(int)
        - types(int)                -> field_type(int)

      - Removed several "smelly" methods:

        - purge()
        - raw_result()
        - reset_names()
        - reset_field_names()
        - reset_types()
        - reset_field_types()

    o Field class used to just be a typedef for the corresponding C
      API class.  Now it's a real C++ class providing a more MySQL++
      sort of interface, plus good OO things like information hiding
      and implementation detail abstraction.  This changes several
      things about the interface.

    o Fields class was basically a specialized std::vector work-alike
      for dealing with the C API to get access to MYSQL_FIELD objects
      and present them as contained Field objects.  New Field type
      let us replace it with "typedef std::vector<Field> Fields"

    o Major improvements to the quoting and escaping mechanisms:

      - Replaced almost all of the type-specific interfaces in manip.h
        with a single version taking STA.  The compiler can convert
        almost anything to STA without losing any information we need
        for correct quoting and escaping.  This has the side benefit
        that we can now do correct quoting and escaping for more data
        types now, including plain C and C++ string types.

      - Fixed a bug in quote_double_only manipulator for String: was
        using single quotes by mistake.

      - Escaping and quoting only works in instances where MySQL++
        can tell you're building a SQL query and are using a data type
        that requires it.  This affects many things, but the one most
        likely to cause trouble is that inserting MySQL++'s quoting
        and escaping manipulators in non-Query ostreams is now a no-op.

      - Added escape_string() member functions to Query and
        SQLQueryParms::escape_string(), and removed the global function
        of the same name.  Because these are tied indirectly to a
        Connection object, this also has the effect that escaping is
        now aware of the current default character set used by the
        database server.  There's only one case where this isn't done
        now, and that's when we're disconnected from the server.

      - Previous two items form a trade-off: if your code was depending
        on MySQL++ to get SQL escaping and it no longer happens for
        what we consider a good reason, you can build a replacement
        mechanism using these new functions.  Quoting needs no special
        support in MySQL++.

      - Removed 'r' and 'R' template query parameter modifiers,
        which meant "always quote" and "always quote and escape"
        regardless of the data type of the parameter.  There are no
        corresponding manipulators (for good reason), so the removal
        restores symmetry.

    o Created DBDriver class from code previously in Connection and
      Query to almost completely wrap the low-level MySQL C API:

      - Connection creates a DBDriver object upon connection and
        passes a pointer to it down to Query objects it creates.
        In turn, they pass the pointer on to any of their children
        that need access to the C API.

      - Nothing outside DBDriver calls the C API directly now, though
        DBDriver leaks C API data structures quite a lot, so this
        feature doesn't constitute "database independence."  See the
        Wishlist for what must be done to get to that point.

    o Completely redesigned the connection option setting mechanism:

      - There's now just a single Connection::set_option() method that
        takes a pointer to the abstract Option base class, and there is
        an Option subclass for every connection option we understand.
        Thus, type errors are now caught at compile time instead of
        at run time.

      - Replaced Connection::enable_ssl() with SslOption class.

      - Enabling data compression and setting the connection timeout
        are no longer set via parameters to Connection interfaces.
        These are now set with CompressOption and ConnectTimeoutOption.

      - Similarly, removed client_flag parameters from Connection's
        ctor and connect() method and added corresponding Option
        subclasses.  There's about a dozen, so rather than list them
        here, look for similarly-named classes in lib/options.h.

    o Added Connection::count_rows() to execute "SELECT COUNT(*) FROM
      tablename" queries for you.

    o Moved Connection::affected_rows(), info() and insert_id() methods
      to class Query, as they relate to the most recently-executed
      query, not to the connection.

    o Several method name changes in Connection:

      - client_info()   -> client_version()
      - host_info()     -> ipc_info()
      - proto_info()    -> protocol_version()
      - server_info()   -> server_version()
      - stat()          -> status()

    o Removed Connection::api_version().  It does the same thing as
      client_version().

    o Lots of changes to Date, DateTime, and Time classes:

      - If you use the default constructor for DateTime and don't
        subsequently set its year, month, day, hour, minute or second
        data members to nonzero values, it becomes the SQL function
        "NOW()" in a query string.  You can also use DateTime::now()
        as syntactic sugar for this.

      - As a result of above, had to hide all of DateTime's data
        members behind accessor functions, to keep the state of the
        object consistent.  (If it's initialized as "now" and you
        give it an explicit year value, say, it is no longer "now",
        so the setter has to clear the now-flag.)  There are getters
        and setters for year, month, day, hour, minute and second,
        all named after the member.

      - Did the same for Date and Time for consistency, even though it
        isn't technically required.

      - The sql_timestamp typedef now aliases DateTime instead of Time.

      - Renamed template class DTbase<T> to Comparable<T>.  The fact
        that it's the common base class of all date and time classes
        is irrelevant; making subclasses comparable is what it does,
        so that's what it should be named after.

      - Added a DateTime ctor taking discrete year, month, day, hour,
        minute, and second values.

      - Implicit conversion from stringish types to the date and time
        types is no longer allowed.  This is part of the "Waba"
        Null<T> patch mentioned above; allowing implicit conversions
        would break this new feature.

      - Added operator std::string and str() methods to all of these
        classes.  Adding this to the existing operator << support, you
        now have several ways to convert these objects to string form.

      - Added time_t conversion to Date and Time classes.  DateTime
        already had it, since it's more legitimate to convert time_t
        to DateTime, but you could already "slice" it with something
        like Time(DateTime(time(0))) so there's no point pretending
        you can't get from time_t to Date or Time.  Might as well
        legitimize it.

    o Improved tiny_int class:
        
      - Turned it into a template parameterized on the value type so
        you can get both signed and unsigned TINYINTs

      - Changed the sql_tinyint and sql_tinyint_unsigned typedefs to
        use mysqlpp::tiny_int<VT> instead of raw chars

      - Added a bool conversion ctor and operator, and typedef'd it
        to sql_bool and sql_boolean to match MySQL server behavior

    o Added many more sql_* typedefs.  We now have a typedef for every
      type the MySQL server knows about, including those it supports
      just for compatibility with other database servers.

    o Changed the sql_*int* typedefs to use integer types of the same
      size as the MySQL server.  (Run test/inttypes.cpp to test it.)

    o Added copy ctor and assignment operator to Row.

    o Row::operator[]() takes int now instead of unsigned int.
      This finally (!) makes it possible to say row[0] without the
      compiler giving an ambiguous overload error.

    o Changed all uses of row.at(0) in the examples to row[0]

    o Added operator[] to all classes that only had at().

    o Query now automatically resets itself unless the query fails
      or you're using template queries.  In either case, the contents
      of the query's internal buffers are considered precious,
      either for debugging, or future queries.  Except when using
      template queries, this means you may be able to avoid calling
      Query::reset() entirely.  It's still safe to call reset()
      as before, just unnecessary most of the time.

    o Removed reset_query parameter from all Query methods.  It was
      almost completely broken before, and above change does what
      was really wanted to begin with.

    o Query::store_next() and Result::fetch_row() no longer throw
      the EndOfResults and EndOfResultSets exceptions; these are not
      exceptional conditions!  These methods simply return false now.

    o Removed examples/usequery.cpp: there's no essential difference
      between what it did and what examples/simple3.cpp does now as
      a result of the previous change.

    o Added Query::exec(void), paralleling Query::execute(void).

    o Removed Query::preview().  The most direct replacement is str(),
      which has always done the same thing.

    o You can now insert a Query object into an ostream to get a copy
      of the built query.  This means Query::str() is only necessary
      when using template queries.

    o Removed overloads of Query::execute(), store(), and use()
      that take const char*.  It was redundant because const char*
      converts implicitly to STA, for which overloads already exist.

    o Renamed Query::def to Query::template_defaults to make its
      purpose clearer.

    o Query::error() now returns const char*, not a std::string by
      value.  There's no point in making a copy of the error string.
      The method is now const as well, as it doesn't change the
      Query object.

    o Added Query::errnum(), which just wraps Connection::errnum().

    o Added error number parameters and accessor functions to BadQuery,
      ConnectionFailed and DBSelectionFailed exceptions, to preserve
      the state of Connection::errnum() at the point of the exception,
      so you don't have to rely on this value remaining unchanged
      during the exception throw process.  All places that use these
      exceptions now include this value where possible.  Thanks for the
      initial patch go to Jim Wallace.

    o Removed Lockable mechanism from Connection and Query; it was
      conceptually flawed.  See the new user manual chapter on
      threading for advice on using MySQL++ safely without locking.
      There is mutex locking now in ConnectionPool, but that's it.

    o Connection::query() now takes an optional query string, allowing
      the returned Query object to start off with a value.  Especially
      useful when the query string is static, either because it's
      a simple query or because it's a template.  You can now build
      chains like "if (conn.query("CREATE INDEX ...").exec()) { ..."

    o Added Connection::thread_aware(), thread_end(), thread_id()
      and thread_safe().  See user manual's threading chapter for
      explanations.

    o Renamed "success" data members in Connection, Query and
      SimpleResult (neé ResNSel) to "copacetic_", making them private
      if they weren't before.  This better reflects their actual
      use, which isn't to say that there has necessarily been actual
      success, but rather that everything's okay with the object.

    o Removed success() member functions from above classes.  All can
      be tested in bool context to get the same information.

    o Replaced all operator bool()s in MySQL++ classes with safer
      alternatives.  See http://www.artima.com/cppsource/safebool.html
      Thanks to Jonathan Wakely for much helpful commentary, advice,
      and code used in these mechanisms.

    o Decoupled Connection::copacetic_ from Connection::is_connected_.
      It is now possible for the object to be copacetic without being
      connected.  However, if it tries to connect and fails, then
      it is not copacetic.  If it is copacetic and not connected, it
      means we haven't even tried to connect yet, a useful distinction.

    o Collapsed Connection's host, port, and socket_name down into
      a new combined 'server' parameter which is parsed to determine
      what kind of connection you mean.  These interfaces are still
      compatible with v2.3 and earlier up through the port parameter.
      There are differences beyond this.

    o Added TCPConnection, UnixDomainSocketConnection and
      WindowsNamedPipeConnection subclasses for Connection giving
      simpler construction and connect() method interfaces for
      instances where you know what kind of connection you want at
      compile time.

    o Changed Connection::ping() return value from int to bool.

    o Renamed NullisNull to NullIsNull -- capital I -- and similar for
      NullisZero and NullisBlank.

    o It's now a compile-time error to try to convert a MySQL++
      representation of a SQL null to any other data type, rather
      than a run-time error as in previous versions.  Removed
      BadNullConversion exception as a result.

    o Way back in v1.7.x we used the BadQuery exception for all kinds
      of exceptional conditions, not just bad queries.  Replaced
      most of these in v2.0.0 with new dedicated exceptions, but a
      few remained:
      
      - Errors that occur during the processing of a "use" query after
        the query itself executes correctly now throw UseQueryError.
        It's not a "bad query", because the query executed
        successfully.  It just choked during subsequent processing,
        so it's a different exception.  Thanks for this patch go to
        Jim Wallace.

      - Replaced BadQuery exceptions thrown in Row constructor due
        to bad ctor parameters with new ObjectNotInitialized exception
        This is also Jim Wallace's work.

    o The examples now all use getopt() type command line options
      instead of positional options.  This makes it possible to
      pass options in any order, leave at their default options that
      used to be in the middle of the sequence, and offer different
      subsets of options for different programs.  Also allows for
      special internal-use options, like -D passed by dtest to let
      examples change their behavior when run under dtest to produce
      only predictable output.

    o Split old libutil functionality into two modules, one holding
      all the "print data" functions, and another holding all the
      command line parsing stuff.  This makes it easier for newbies
      to ignore the command line stuff, treating it like a black box.
      The wish to understand the "print data" routines is much more
      common, so the two needed to be disentangled.

    o Renamed examples' libutil to libexcommon.

    o Removed connect_to_db() libutil function.  It combined command
      line parsing, which users don't care about, with database
      connection establishment, which they do care about.  Now the
      examples just call out to libexcommon to parse the command
      line, and use the values they get back to explicitly make the
      connection, so it isn't hidden.

    o Removed cchar and uint typedefs.

    o Redesigned dbinfo example's output to be easier to read.

    o Fixed an output formatting bug created in 2.3.0 that caused the
      tabular output from examples to not line up.

    o Renamed examples/tquery.cpp to tquery1.cpp.  Created tquery2.cpp
      to demonstrate passing parameters via a SQLQueryParametrs object
      instead of discretely.  Created tquery3.cpp for testing unquoted
      template parameters, such as integers.

    o Renamed fieldinf1.cpp example to fieldinf.cpp, and simplified
      its output so it can be part of the dtest sequence.

    o Renamed examples/xaction.cpp to transaction.cpp.  It created too
      much cognotive dissonance whenever thinking about both it and
      lib/transaction.cpp.

    o Added examples/deadlock.cpp, to test handling of exceptions due
      to server-side transaction deadlock detection.  Also added
      code to resetdb to create a table needed to test this.
      Initial version created by Jim Wallace to test the value of
      all his BadQuery exception work, with reworking by me.

    o Greatly expanded dtest suite.  Primary change is that we now
      have a handful of unit tests, where in v2.3.2 we only tested
      a subset of the examples.  Still very low coverage ratio,
      but it's a big improvement.

    o Optimized #includes, especially in lib/*.h to reduce
      dependencies and thus compile time when one of these changes.

    o Fixed a typo in RPM filename generation that prevented -devel
      RPM from recognizing that the corresponding MySQL++ library
      RPM was installed.

    o RPM spec file improvements by Remi Collet.

    o Renamed NO_LONG_LONGS to MYSQLPP_NO_LONG_LONGS to avoid a risk
      of collision in the global macro namespace.
    
    o First cut at Xcode2 project support.  Testing needed!

    o Debug build of library on VC++ and Xcode have a _d suffix now
      so you can have both versions of the library installed without
      conflict.

    o Moved the VC++ 2003 project files into a new vs2003 subdirectory
      because there are so many of them.  Also created vs2005
      subdirectory for VC++ 2005 and 2008 compatible project files.
      2005 makes an even bigger mess of the directory containing
      the .sln file, so the incentive is bigger.  Plus, we have to
      disable several things to get VC++ 2003 to build MySQL++ now,
      so we need a special 2005+ version of the project files for a
      complete build, if the user has one of the newer compilers.

    o ...plus dozens of small bug fixes and internal enhancements,
      many documentation improvements, and expansion of support for
      newer operating systems and compilers.


2.3.2, 2007.07.11 (r1669)

    o Previous release's const_string change caused more problems
      than it fixed.  This release contains the real fix. :)

    o New Connection::set_option() handling deals with the multi
      statements option correctly again.  examples/multiquery now
      runs again as a result.

    o Added new unit testing script, called dtest.  See the
      HACKERS file for details.  (This tool caught the previous
      two problems!)

    o Squished a GCC pedantic warning.  Thanks for the patch go to
      Andrew Sayers.


2.3.1, 2007.07.10 (r1659) The "After the Fireworks" release

    o const_string objects now keep a copy of their data, not
      just a pointer to it.  This is less efficient, but necessary
      to allow SSQLS to work with BLOBs.  Without this, we were
      seeing segfaults due to accessing freed memory pointed to
      by the const_string, because the underlying object went
      out of scope.

    o Fixed many more potential embedded null handling problems
      in manip.h.

    o MySQL++ can now optionally reference MySQL C API headers as
      being in a mysql subdirectory, a common thing on *ix systems,
      by defining MYSQLPP_MYSQL_HEADERS_BURIED before #including
      mysql++.h.

    o Restored ColData_Tmpl<T>::get_string(), removed in v2.3.0,
      along with warnings in the docs saying why you don't want
      to use it, and what your alternatives are.

    o VC++ and MinGW builds now define the HAVE_MYSQL_SSL_SET
      macro, which lets you use the C API's SSL features.
      This assumes your C API library does actually have these
      features enabled, which is the case with the official binary
      releases on Windows.  (Builds on *ix systems continue to
      test for these features at configure time.)

    o Fixed simple examples-only Makefile generation, for RPMs.


2.3.0, 2007.07.02 (r1645)

    o Added Query::for_each() and Query::store_if() methods
      proposed by Joel Fielder, and added examples for each.

    o It's now possible to store BLOB data in an SSQLS.  It's not
      foolproof, so added a section to the user manual (5.9) to
      document the method.  Also, changed examples/cgi_jpeg to use
      this new mechanism, instead of the ugly "raw row data" method
      it used to use.

    o Revamped Connection::set_option() handling.  These options
      used to be queued up, and applied only just before actually
      establishing the connection.  This made error reporting less
      helpful because the diagnostic was separated from the cause.
      Plus, the error messages were misleading to begin with.  Now,
      set_option() takes effect immediately if the connection is not
      yet up (excepting one special option that can actually be set
      after the connection is up) and issues better diagnostics when
      it detects errors.

    o Connection::connect() used to set a few options in such a
      way that the user couldn't override them.  Now it's smart enough
      to set them with the desired default values only when we see
      that the user hasn't given them other values.

    o SQLString can now be initialized from a mysqlpp::null,
      giving a "NULL" string.  This is useful for template queries.
      Patch by Michael Hanselmann.

    o resetdb error message about mixing library and header version
      numbers is now more explicit.

    o Changed BadConversion exception's "what" message text to be
      more like the other exceptions.  The inconsistency lead one
      to incorrectly copy-paste code from another exception handler,
      expecting it to behave the same way.  Now it does.

    o Added Row::raw_size(), as a shortcut for Row::at().size().

    o ssqls-pretty now detects when it's being run from within
      the MySQL++ distribution tree and gives a different -I flag
      to the compiler, so that it picks up the distribution headers
      instead of those that may be on the system already.

    o The quote manipulator now works for char[] correctly.
      Thanks for this patch go to Andrew Sayers.  (It's always
      worked for char*, but C++ doesn't consider that to be the
      same type, so it used the generic quote handling path,
      which doesn't do anything for char[].)

    o Fixed a build bug on older Solaris versions where the
      test for the C API library was erroneously failing, stopping
      the configuration process.

    o Simplified mysql_shutdown() level argument detection.
      Already had to do a version number ifdef check for the
      Windows case, so there's really no point to doing it with
      autoconf on Unixy platforms.  Moved version number check
      into lib/connection.cpp, and nuked the separate autoconf and
      Windows tests.

    o Removed dependency of sql_types.h on myset.h and (indirectly)
      datetime.h.  Now we only define sql_* typedef aliases for those
      MySQL++ types if the headers are included before sql_types.h.

    o Fixed a typo in one of the storein_sequence() template
      overloads, which is apparently rarely (or never?) used, because
      no one reported the compiler error you'd get if you tried.

    o Fixed a few more embedded null handling problems.

    o ColData used to keep two copies of all data it held.
      Now it keeps just one.

    o Fixed install.bat script to track the unified Bakefile change
      and the lack of separate debug and release builds under MinGW.

    o Yet another STLport + Query memory leak fix.

    o Squished a warning in newer GCCs having to do with identifier
      shadowing.  Patch by Jonathan Wakely.

    o Fixed a null-termination bug in Query::parse().  If you
      somehow constructed a query string without a terminating null
      character, then tried to parse it as a template query, it could
      walk off the end of the string.  Patch by Worster Chen.

    o Removed MYSQLPP_EXPORT tag from FieldNames and FieldTypes
      class declarations, as this can cause problems in programs
      that use vector<string> in VC++.  It has to do with multiply
      defined templates, since these classes derive from that
      template, and VC++ can't resolve the conflict without help.
      Since these classes aren't actually used outside the library,
      this shouldn't cause a problem.  Patch by Nils Woetzel.

    o Partial fix to Doxygen PDF build on RHEL4 and 5.  Needs
      hand-coaxing to complete successfully on RHEL4, and doesn't
      yet work at all on RHEL5.

    o Shortened the "no*" options to the bootstrap script, so that
      the usage message fits on a single line.

    o Added "nodoc" bootstrap script option, for disabling the
      documentation build during the dist target build.  Allows for
      building binary RPMs on CentOS 5.0, where doc building is
      currently broken.

    o Removed the updel example program.  It was kind of silly,
      and if you were to rewrite it today, you'd use for_each() anyway.

    o Lots of documentation improvements.


2.2.3, 2007.04.17 (r1538) The "Tax Day" release

    o Previous version left examples/vstudio/* out of the tarball
      by accident.

    o Improved generation of RPM temporary build directory path
      name generation.  Was using a hacked variant of the Fedora
      Packaging Guidelines' second best choice.  Now we're using
      the choice they recommend most highly, without changes.

    o Removed unnecessary resources from vstudio/wforms example.

    o Minor URL fix in refman


2.2.2, 2007.04.13 (r1526) The "Nervousmaking Friday the 13th" release

    o More small fixes to embedded null handling in Query.

    o Fixed a bug in single-parameter template query handling.

    o Added tquery example, to demonstrate proper use of template
      queries.  Previously, resetdb was the only exemplar, and
      it wasn't really suited for that.  This example also tests
      the previous item.

    o Added examples/vstudio/mfc, allowing us to improve the way
      we demonstrate Unicode handling.  Old way wasn't realistic.
      On *ix, people will depend on the terminal code to handle
      UTF-8.  On Windows, users are almost certain to be writing
      a GUI program, which requires different Unicode handling
      than the old examples showed.

    o Removed explicit Unicode conversion stuff from command line
      examples, and reworked the Unicode chapter in the user
      manual.
    
    o Added examples/vstudio/wforms to show integration with
      C++/CLI and Windows Forms.  Documented this in README.vc.

    o Rewrote load_file and cgi_image examples to be more
      useful, renaming them to load_jpeg and cgi_jpeg along
      the way.  Also, resetdb now creates a second table in the
      sample database for these two examples' use.  Also, added
      examples/logo.jpg to the distribution as sample data for
      these examples.

    o Limited the ostream base class casting stuff in Query to
      VC++ 2003, which is the only platform that really needed it.
      VC++ 2005 emits a warning with that hack in place, and on
      other platforms it's just replicating work that the compiler
      does already.

    o Added library version information to main library target
      so that systems that version shared libraries work as
      expected.  Thanks for this patch go to Jack Eidsness.

    o Merged much of the diffs between Remi Collet's RPM spec file
      into the official one.

    o Reorganized the doc subdir a bit.  Generated HTML is now all
      under doc/html instead of scattered under other subdirs,
      and renamed doc/README.mysql++ to doc/README.manuals.

    o Improvements to top-level manual building make targets:
      manuals now only rebuild at need, it's easier to request
      a rebuild of all manuals, and we force a rebuild attempt
      before building the distribution tarball so we don't ship
      outdated manuals.

    o Added ability to run examples under gdb using exrun,
      using same mechanism as we currently have for valgrind.
      Thanks for this patch go to Michael Hanselmann.

    o Added "Important Underlying C API Limitations" chapter to the
      user manual, to cover problems we keep seeing on the
      mailing list that are the result of ignorance of the way
      libmysqlclient behaves, not bugs MySQL++ is really in a
      position to fix.


2.2.1, 2007.02.28 (r1433)

    o Fixed the new localtime() alternative selection code
      for VS2003 and various uses of STLport.

    o No longer inserting a null character into the query stream
      on calling one of the preview() functions.  This was harmless
      in v2.1, which used C strings more extensively, but began
      causing problems in v2.2 due to its wider use of C++ strings.

    o Fixed a bug in the Connection copy ctor where it didn't
      completely initialize the object.

    o Optimized Query::preview_char() a bit.  Patch by Jonathan
      Wakely.

    o Reordered directory list used by autconf when locating the
      MySQL C API library.  The list is now ordered with the
      most likely locations for the library first, so we're less
      distracted by incorrect libraries.  This fixes a specific
      build error under RHEL4 with recent versions of MySQL 5.0.


2.2.0, 2007.01.23 (r1417)

    o ColData, const_string, and SQLString can now be constructed
      with an explicit length parameter.  Furthermore, Query
      class's execute(), store() and use() call chains terminate
      in a version taking an explicit length parameter, instead
      of one taking a simple C string.  Together, this means
      that it's now easier to handle data from the SQL server
      containing nulls.  The library is almost certainly not yet
      capable of handling embedded nulls in all cases, but this
      is a big first step towards that.

    o Can now construct a DateTime object from a time_t, and
      convert a DateTime back to a time_t.  Patch by Korolyov Ilya.

    o Changed the way we're handling exported functions in the
      Windows DLL case so that it works more reliably under MinGW.

    o Added proper copy semantics to Connection, so that you get a
      new connection with the same parameters, not just a bitwise
      copy of the object.

    o Using an explicitly thread-safe variant of localtime() for
      time conversions where one is available.

    o Removed ListInsert template from myset.h.  This wasn't used
      within the library, and was never documented, so I'm betting
      that no one actually uses it.

    o Result::copy() was not copying the exception flag in
      all cases.  Fix by Steven Van Ingelgem.

    o Added exrun shell script and exrun.bat files to distribution,
      to avoid linkage errors when running the examples while
      you still have an older version of MySQL++ installed.

    o Renamed MYSQLPP_LIB_VERSION to MYSQLPP_HEADER_VERSION, as
      what it really encodes is the version number in the mysql++.h
      file you're using, not the actual library version number.

    o Added mysqlpp::get_library_version(), which returns the
      library version number at build time.  Between this and
      the header version constant, you can check that you're not
      mixing MySQL++ header and library versions.

    o resetdb example uses these new version number affordances to
      double-check that you're not mixing libraries and headers
      from different versions.  This happens easily unless you
      take care of it (such as by using exrun) when you have one
      version of MySQL++ installed and you're trying to build and
      test a new version without blowing away the old one first
      or overwriting it.

    o No longer using recursive Makefiles on Unixy platforms
      or split lib + examples project files on VC++.  Everything is
      handled by a single top-level Makefile or project file, which
      is simpler for the end user, and makes better dependency
      management possible.

    o When looking for the MySQL C library on systems using
      autoconf, looking in .../lib64 wherever we are also looking
      in .../lib.

    o RPM build process no longer depends on Bakefile.  It means
      you have to build the examples when building an RPM even
      though they're never used within the RPM, but it's a better
      tradeoff in my opinion.

    o Updated include and library paths on Windows to reflect
      changes in the most recent MySQL installers.

    o Merged lib/defs.h and lib/platform.h into new file,
      lib/common.h.  Just cleans up the library internals.

    o Fixed build errors on Windows due to recent changes in MySQL.

    o Fixed a few memory leaks and double-deletes in Query class.

    o Fixed compatibility with STLPort's string implementation.
      Patch by dengxy at cse.buaa.edu.cn.

    o Fixed a compatibility problem between Set<> template and
      SSQLS.  Patch by Korolyov Ilya.

    o Fixed build bug in SQLQueryParms due to a character
      signedness issue on PowerPC with GCC.  Patch by Michael
      Hanselmann.

    o ~Transaction() can no longer throw exceptions.  It'll just
      quietly eat them, to avoid program termination.  Fix
      suggested by Alex Burton.

    o Fixed thread safety testing in autoconf case, accidentally
      broken during v2.1.0 development cycle.

    o Using Doxygen 1.5.1 to generate documentation.


2.1.1, 2006.04.04 (r1289)

    o MinGW and Cygwin will now build and link to mysqlpp DLLs.

    o Fixed bug in Query, causing it to initialize the "throw
      exceptions" flag incorrectly.  Thanks for this patch go to
      Joel Fielder.

    o Added -v flag for custom.pl script, which turns off the
      multiply-defined static variable fix.  Needed for VS 2003,
      which doesn't support variadic macros.  Also, added
      a diagnostic to detect the need for the -v flag, and
      suppressed the test for this feature in examples/util.cpp.


2.1.0, 2006.03.24 (r1269)

    o Converted automake and makemake files to their equivalents in
      Bakefile format.

    o Added the Transaction class, which makes it easy to use
      transaction sets in MySQL++.

    o Added xaction example to test new Transaction class.

    o Resetdb example now creates its example table using the
      InnoDB storage engine, in order to test the new transaction
      support.  Resetdb also declares the table as using UTF-8
      text; this doesn't change anything, but it does correctly
      document what we're doing.

    o Added sql_types.h header, containing C++ typedefs
      corresponding to each MySQL column type.  Using those new
      types in the type_info module, and in the SSQLS examples.

    o Replaced the way we were handling the template query
      version of Query member functions, to allow an arbitrary
      number of template query parameters.  By default, we
      now support 25 parameters, up from the old limit of 12.
      It's now possible to change just one number, run a script,
      and have a new limit.

    o Connection class does a better job of returning error
      messages if you call certain member functions that depend
      on a connection to the server before the connection is
      established.

    o Updated libmysqlclient.def for newer versions of MySQL.  (Fixes
      build errors having to do with mysql_more_results() and
      mysql_next_result().

    o Replaced final use of strcpy() with strncpy().

    o custom.pl now runs without complaint in strict mode, with
      warnings turned on.  Thanks for this patch go to "Waba".

    o Fixed a bug in custom.pl where incorrect code would be
      generated for some SSQLS set() methods.  Thanks for this
      patch go to "Waba".

    o SSQLS structures now support long and unsigned long fields.
      Thanks for this patch go to "Waba".

    o It's now possible to put SSQLS definitions in a header
      file used by multiple modules in a program without
      getting multiple static member definition errors.  See the
      documentation for details.  Thanks for this patch go to
      Viktor Stark.

    o Moved the definition of the 'stock' SSQLS out of the
      custom*.cpp example files and into a new stock.h file.
      Also, #including that file in the util module to test out
      the new SSQLS multiple static definition fix.

    o Using all of the digits of precision guaranteed by the
      IEEE 754 spec when stringizing floating point numbers
      to build queries.  Previously, we would use the platform
      default, which can be as few as 6 digits.

    o Removed lib/compare.h.  Not used within the library, never
      documented, and nobody seems to want to defend it.


2.0.7, 2005.11.23 (r1147)

    o Added explicit mysqlpp namespace qualifiers to generated code in
      custom*.h so you can use SSQLS in places where it doesn't make
      sense to say "using namespace mysqlpp" before the declaration.
      Also updated some of the examples to not have this "using"
      declaration to make it clear to users that it isn't needed, if you
      want to use explicit namespace qualifiers as well.  Thanks for
      this patch to Chris Frey.

    o Removed an apparently useless unlock() call from ResUse; there is
      no nearby lock() call, so if this unlock() is in fact necessary,
      it shouldn't be here anyway, because the two calls should be
      nearby each other.  Thanks for this patch to Chris Frey.

    o Fixed Query ostream initialization bug affecting SunPro CC (at
      least).  While this bug violates the Standard, it doesn't affect
      many real compilers because they don't enforce this rule.  Fixed
      by Chris Frey.

    o Previously, we only used the C99 style "long long" support when
      building under GNU CC.  This is now the default.  This should
      allow the code to work under SunPro CC.

    o Added another dynamic cast needed for proper Query ostream
      subclass overloading under VC++.  (7.1 at least...)

    o Detecting whether MySQL is built with SSL support on platforms
      using autotools.  Needed on some old Sun systems, for instance.
      Thanks for this patch to Ovidiu Bivolaru.

    o Fixed a potential memory bug in ColData's conversion to SQL null.

    o Many minor packaging tweaks.  (README clarifications, file
      permission fixes, better adherence to GNU packaging standards,
      etc.)

    
2.0.6, 2005.09.28 (r1123)

    o Fixed makemake.bat so it works on cmd.exe, not just 4NT.

    o Documentation fixes.


2.0.5, 2005.09.13 (r1114)

    o Visual C++ build now requires GNU make.  It is tested to work
      with either the Cygwin or the MinGW versions.  The previous
      version of MySQL++ used nmake.  This change enabled the
      following features:

        o Debug and Release versions are both built into
          separate subdirectories.

        o Dependency tracking for release version works
          correctly now.  (Previously dependencies worked
          only for debug version.)

        o 'make clean' removes release version binaries
          in addition to debug versions.

    o MinGW makemake support updated to support new release/debug
      subdirectory system.  This is probationary support, since
      this code currently can't be built as a DLL.  As a result,
      it is no more useful than the Cygwin version, for licensing
      reasons.

    o Several fixes to allow building on Solaris 8.  These fixes may
      also help on other SVR4-derived systems.

    o Removed Borland C++ makemake support, because this version
      of the library does not work completely, and there seems
      to be almost no user interest in fixing it.
      
    o Clarified "Handling SQL Nulls" section of user manual's
      Tutorial chapter.


2.0.4, 2005.08.29 (r1076)

    o Made mysql_shutdown() second parameter autoconf check less
      sensitive to compiler pedantry.

    o VC++ library Makefile is now smart enough to re-create the
      import library, if it is deleted while leaving the DLL alone.

    o Added libmysqlclient.def to tarball.

    o Reworked most of the top-level README* files.

    o Renamed LGPL file to LICENSE.


2.0.3, 2005.08.25 (r1060)

    o Visual C++ makemake system updated to build both debug and
      release versions of library DLL.

    o Fixed bug in simple1 example that caused crashes on Windows.

    o Doing UTF-8 to ANSI text translation in simple examples now.

    o Previous two releases built libmysqlpp with wrong soname on
      autotools-based systems.  Fixed.


2.0.2, 2005.08.18 (r1050)

    o Fixes to makemake system for cmd.exe.

    o Fixed the case where the system's C++ library includes an slist
      implementation in namespace std.


2.0.1, 2005.08.17 (r1046)

    o Added new simple1 example, showing how to retrieve just one
      column from a table.  Old simple1 is now called simple2, and
      simple2 is likewise shifted to simple3.

    o Added custom6 example, showing how to do the same thing with
      SSQLS.

    o Updated user manual to cover new examples.

    o Was accidentally shipping Subversion crap with tarball.  Fixed.


2.0.0, 2005.08.16 (r1031) The "Excess Hair Removal" release

    THIS IS NOT A DROP-IN REPLACEMENT FOR MySQL++ v1.7!

    At minimum, you will have to recompile your program against
    this library.  You may also have to make code changes.
    Please see the "Incompatible Library Changes" chapter of
    the user manual for a guide to migrating your code to this
    new version:

        http://tangentsoft.net/mysql++/doc/html/userman/breakages.html

    o The library's shared object file name (soname) scheme has
      changed.  (This mainly affects POSIX systems.)
      
      The soname for the last 1.7.x releases of MySQL++ was
      libmysqlpp.so.4, meaning the fourth version of the library's
      application binary interface (ABI).  (The first ABI version
      in this scheme was that provided by 1.7.9.)  MySQL++
      2.0.0's soname is libmysqlpp.so.2.0.0.  Since the dynamic
      linker setup on some systems will create a symlink to
      that file called libmysqlpp.so.2, it's possible that this
      library could be confused with that for MySQL++ 1.7.19
      through .21, which also used this number.  Do not install
      this library on a system which still has binaries linked
      against that version of the library!

      The new scheme is {ABI}.{feature}.{bug fix}.  That is,
      the first number changes whenever we break the library's
      binary interface; the second changes when adding features
      that do not break the ABI; and the last changes when the
      release contains only internal bug fixes.  This means
      that we will probably end up with MySQL++ 3.0 and 4.0 at
      some point, so there will be further soname conflicts.
      Hopefully we can put these ABI changes off long enough
      to avoid any real problems.

    o autoconf now installs headers into $prefix/include/mysql++,
      instead of $prefix/include.  If you were using the
      --includedir configure script option to get this behavior
      before, you no longer need it.

    o Linux binary RPMs will henceforth include only the
      libmysqlpp.so.X.Y.Z file, and create any short names
      required, to allow multiple versions to be installed at
      once.  Currently, you cannot install two MySQL++ library
      RPMs at once, because they both have /usr/lib/libmysqlpp.so.X,
      for instance.

    o Replaced the Visual C++ and Borland C++ project files with
      a new "makemake" system, which creates Makefiles specific
      to a particular toolchain.  This new mechanism also supports
      MinGW and generic GCC-on-*ix.  This was done partly to reduce
      the number of places we have to change when changing the
      file names in MySQL++ or adding new ones, and partly so we're
      not tied to one particular version of each of these tools.

    o VC++ Makefiles create a DLL version of the library only
      now, so there's no excuse for LGPL violations now.
      This same mechanism should make DLL builds under other
      Windows compilers easy.

    o Added Connection::enable_ssl(), which enables encrypted
      connections to the database server using SSL.

    o Connection::create_db() and drop_db() now return true on
      success, not false.

    o Connection::create_db() and drop_db() use Query::exec()
      now, for efficiency, rather than Query::execute().

    o Removed Connection::infoo().  Apparently just there to
      save you from a typo when calling the info() method, since
      it was a mere alias.

    o Renamed Connection::real_connect() to connect(), gave
      several more of its parameters defaults, and removed old
      connect() function.  Then changed user manual and examples
      to use new APIs.

    o Replaced Connection::read_option() with new set_option()
      mechanism.  The name change matches the method's purpose
      better.  Functional changes are that it returns true on
      success instead of 0, it supports a broader set of options
      than read_option() did, and it enforces the correct option
      argument type.

    o You can now call Connection::set_option() before the
      connection is established, which will simply queue the option
      request up until the connection comes up.  If you use this
      feature, you should use exceptions, because that's the only
      way an option setting failure can be signalled in this case.

    o Removed query-building functions (exec*(), store*(),
      use()) from class Connection, and moved all the implementation
      code to class Query.  Query no longer delegates the final
      step of sending the query to the database server to
      Connection().

    o Added Connection::enable_ssl(), for turning on SSL support on
      a connection.

    o Extracted exception disabling mechanism out of the many
      classes that had the feature into a new OptionalExceptions
      base class, which all classes having this feature now
      derive from.  Also, removed all per-method exception
      handling flags.  Finally, added NoExceptions class.  With
      all of these changes, there is now a common way to disable
      exceptions with fine granularity on all objects that
      support the feature.

    o All custom MySQL++ exceptions now derive from the new
      Exceptions class.  This regularizes the exception interface
      and allows you to use a single catch() block if you want.

    o The "throw exceptions" flag is passed from parent to child
      in all situations now.  (Or if not, please report it as
      a bug.) This fulfills a promise made in the v1.7.9 user
      manual, with the cost being that some programs will see
      new exceptions thrown that they're not expecting.

    o Added a bunch of new exception types: BadOption,
      ConnectionFailed, DBSelectionFailed, EndOfResults,
      EndOfResultSets, LockFailed, and ObjectNotInitialized.
      Some of these replace the use of BadQuery, which in v1.7.x
      was a kind of generic exception, thrown when something more
      specific wasn't available.  Beware, this means that programs
      may start crashing after recompiling them under v2.0 due to
      uncaught exceptions, if they were only trying to catch BadQuery.

      There are additional instances where the library will
      throw new exceptions.  One is when calling a method that
      forces the internals to use an out-of-bounds index on a
      vector; previously, this would just make the program
      likely to crash.  Another is that the library uses the
      BadFieldName exception -- created in v1.7.30 -- in more
      apropos situations.

    o Renamed SQLQueryNEParms to BadParamCount, to match naming
      style of other concrete exception types.

    o Extracted lock()/unlock() functions from Connection and
      Query classes into a new Lockable interface class.  Locking
      is implemented in terms of a different class hierarchy, Lock,
      which allows multiple locking strategies with a single ABI.

    o Removed ResUse::eof().  It's based on a deprecated MySQL
      C API feature, and it isn't needed anyway.

    o Removed arrow operator (->) for iterator returned by Fields,
      Result and Row containers.  It was inherently buggy, because
      a correct arrow operator must return the address of an
      object, but the underlying element access functions in these
      classes (e.g. at()) return objects by value, of necessity.
      Therefore, this operator could only return the address of
      a temporary, which cannot be safely dereferenced.

    o Returned Row subscripting to something more like the
      v1.7.9 scheme: there are two operator[] overloads, one for an
      integer (field by index) and another for const char* (field
      by name).  lookup_by_name() has been removed.  Because row[0]
      is ambiguous again, added Row::at() (by analogy with STL
      sequence containers), which always works.

    o Collapsed two of the Row::value_list*() overloads into
      two other similar functions using default parameters.
      This changes the API, but the removed functions aren't
      used within the library, and I doubt they are used outside,
      either.

    o Merged RowTemplate into Row.

    o Merged SQLQuery class into Query class.

    o Query is now derived from std::ostream instead of
      std::stringstream, and we manage our own internal string
      buffer.

    o Moved SQLParseElement and SQLQueryParms into their own
      module, qparms.

    o Added multiple result set handling to Query.  MySQL 4.1
      and higher allow you to give multiple SQL statements in a
      single "store" call, which requires extensions to MySQL++
      so you can iterate through the multiple result sets.  Also,
      stored procedures in MySQL 5.0 reportedly return multiple
      result sets.  Thanks for the initial patch go to Arnon Jalon;
      I reworked it quite a bit.

    o Query::storein*() now supports more varieties of the
      nonstandard slist comtainer.  (Singly-linked version of
      STL std::list.)

    o Template query mechanism and user manual had several
      mismatches.  Made manual match actual behavior, or
      made library match documented behavior, as apropriate.
      Initial patch by Jürgen MF Gleiss, with corrections and
      enhancements by Warren Young.

    o Collapsed mysql_* date and time base classes' methods and
      data into the subclasses.  Also, DateTime no longer derives
      from Date and Time; you could get away with that in the
      old hierarchy, but now it creates an inheritance diamond,
      and allows unsupported concepts like comparing a Time to
      a DateTime.

    o Removed "field name" form of Row::field_list().  It was
      pretty much redundant -- if you have the field names, why
      do you need a list of field names?

    o ColData can convert itself to bool now.  Thanks for this
      patch go to Byrial Jensen.

    o Removed simp_list_b type; wasn't being used, and doesn't
      look to be useful for end-user code.

    o Several methods that used to take objects by value now
      do so by const reference, for efficiency.

    o Several variable and function renamings so that MySQL++
      isn't needlessly tied to MySQL.  Even if we never make
      the library work with other database servers, there's
      little point in tying this library to MySQL blindly.

    o Renamed all private data members of MySQL++ classes to
      have trailing underscores.

    o 'private' section follows 'public' section in all classes
      now.

    o Removed mysql++.hh and sqlplus.hh backwards-compatibility
      headers.

    o Added copy ctors to Date/Time classes so that they will
      work in SSQLS under GCC 4.0.0.  Without these, the compiler
      couldn't make the conversion from raw MySQL row data.

    o Fixed a bunch of GCC 4.0 pedantic warnings: added virtual
      dtors to all base classes, calling base class ctors from leaf
      classes, etc.

    o All warnings fixed under VC++ at warning level 3.  (Mostly
      harmless signedness and integer conversion stuff.)

    o Updated LGPL license/copyright comments at the top of
      several files to use FSF's new physical address.

    o Relicensed user manual under a close variant of the Linux
      Documentation Project License, as it's designed for
      documentation, which the LGPL is not.  Permission for this
      received from Kevin Atkinson and MySQL AB.

    o Added ABI and API breakages chapter to user manual.  It
      is basically a subset of this ChangeLog, with only the
      information an end-user must know when migrating between
      versions.

    o Reworked user manual's DocBook code quite a bit after
      reading Bob Stayton's book "DocBook XSL" 3/e.  Better handling
      of stylesheets, taking advantage of some superior DocBook
      features, prettier output (especially the HTML version), etc.

    o Rewrote doc/userman/README to make it clearer how to get
      started contributing to the user manual.  It's essentially a
      "getting started with DocBook" guide now!

    o Lots of small text improvements to user and reference
      manuals.  Aside from the obvious tracking of library changes,
      made a bunch of minor style and clarity improvements.

    o Added CSS stylesheets for userman and refman to
      make the HTML versions of each a) not ugly; and b) match
      tangentsoft.net.  (Yes, some may say that these are incompatible
      goals....)

    o Standardized exception handling code in the examples that
      use it.

    o Fixed a potential memory leak due to exceptions thrown from
      ResUse.  Thanks for this patch go to Chris Frey.

    o Using new "no exceptions" feature of library in simple1
      example, so it is now truly simple.

    o simple1 example no longer depends as much on util module, so
      that all of the important code is in one place.  Makes
      learning MySQL++ a little less intimidating.

    o Added new simple2 and usequery examples, to demonstrate
      the proper way to handle a "use" query, with exceptions
      disabled, and not, respectively.  Added them to the user
      manual, in the appropriate place.

    o Refactored the "print stock table" example functions
      again, to make code using them clearer.

    o UTF-8 to UCS-2 handling in examples is now automatic on
      Windows.

    o Removed debug code from Windows Unicode output examples
      that slipped into previous release.

    o resetdb example is now clearer, and more robust in the
      face of database errors.

    o Simplified connect_to_db() in examples' util module.

    o Added sample autoconf macro for finding MySQL++ libraries, for
      people to use in their own autotools-based projects.

    o Lots and lots of minor cleanups not worth mentioning
      individually...


1.7.40, 2005.05.26 (r719)

    o Multiple item form of insert() now works if you're using the
      SQLQuery class, or its derivative, Query.  Thanks to Mark
      Meredino for this patch.

    o Fixed a bug in const_string::compare(), in which MySQL++
      would walk off the end of the shorter of the two strings.
      All was well if the two were the same length.

    o ResUse::operator=() now fully updates the object, so it's more
      like the behavior of the full ctor.

    o All source files now contain a license and copyright statement
      somewhere within them.

    o Optimized mysql++.h a bit: it now #includes only the minimum set
      of files required, and there is now an idempotency guard.
      This improves compile times a smidge, but mainly it was
      done to clean up the generated #include file graph in the
      reference manual.  Before, it was a frightful tangle because
      we #included everything except custom*.h.

    o Constness fix in MySQL++ date/time classes to avoid compiler
      warnings with SSQLS.  Thanks to Wolfram Arnold for this patch.

    o Fixed some compiler warnings in custom*.h.  Thanks to Chris Frey
      for this patch.

    o Added "Submitting Patches" and "Maintaining a Private CVS
      Repository" sections to the HACKERS file.  Thanks to Chris
      Frey for the source material for these sections.  The HACKERS
      file was improved in several other ways at the same time.

    o PDF version of user manual no longer has links to the reference
      manual.  They were ugly, and they were broken anyway due to the
      way we move the PDFs after generating them.  If you want
      interlinked manuals, use the HTML version.

    o PDF version of user manual now has hard page breaks between
      chapters.

    o Removed complic1 example.  Wasn't pulling its own weight.
      Everything it is supposed to demonstrate is shown in other
      examples already.

    o Refactored print_stock_table() in examples/util module to be
      four functions, and made all the examples use various of
      these functions where appropriate.  Before, several of
      the examples had one-off stock table printing code because
      print_stock_table() wasn't exactly the right thing, for one
      reason or another.  One practical problem with this is that
      some of the examples missed out on the recent Unicode updates;
      now such a change affects all examples the same way.

    o Since so many of the examples rely on the util module, the user
      manual now covers it.  The simple1 example in the user manual
      didn't make much sense before, in particular, because it's
      really just a driver for the util module.

    o Added custom5 example.  It shows how to use the equal_list()
      functionality of SSQLS.  Thanks to Chris Frey for the original
      version of this program.  (I simplified it quite a bit after
      accepting it.)

    o New user manual now covers the value_list(), equal_list() and
      field_list() stuff that the old manual covered but which was
      left out in previous versions of the new manaul.  Most of the
      examples are the same, but the prose is almost completely new.
      This new section includes the custom5 example.

    o Every declaration in MySQL++ is now documented in the reference
      manual, or explicitly treated as "internal only".

    o Improved docs for MySQL++'s mechanism to map between MySQL
      server types and C++ types.  Initial doc patch by Chris Frey,
      which I greatly reworked.

    o Improved a lot of existing reference manual documentation while
      adding the new stuff.

    o Expanded greatly on the exception handling discussion in the user
      manual.

    o Added all-new "Quoting and Escaping" section to the user
      manual's Tutorial chapter.  Moved some existing comments on
      quoting and escaping around and added some new ones to other
      sections as a result.

    o Added all-new "Handling SQL Nulls" section to the user manual's
      Tutorial chapter.

    o Many improvements to the Overview section of the user manual.

    o Row::operator[] reference now explains the right and wrong way to
      use the values it returns.  This is in response to a mailing list
      post where someone was incorrectly using this feature and getting
      a bunch of dangling pointers.

    o Updated Doxyfile so 1.3.19.1 parses it without warnings.  Still
      works with versions back to 1.2.18, at least.  (These are
      the versions shipped with Fedora Core 3 and Red Hat Linux 9,
      respectively.)

    o Using a superior method to make Doxygen ignore certain sections
      of the source code.  Between this change and the fact that
      everything not so ignored is documented, Doxygen no longer
      generates any warnings.

    o Lots of code style updates.  Everything should now be consistently
      formatted.


1.7.35, 2005.05.05 (r601) The "Cinco de Mayo" release

    o Added a "how to use Unicode with MySQL++" chapter to the user
      manual.  (Too bad "Cinco de Mayo" doesn't have any accented
      characters.  That would be just _too_ precious.)

    o VC++ examples now use the Unicode Win32 APIs, so they can display
      Unicode data from MySQL++.

    o Added an optional conversion function to examples/util.cpp to
      handle the conversion from UTF-8 to UCS-2 on Win32.

    o Moved "brief history of MySQL++" from intro section of refman to
      intro section of userman.

    o Lots of small bits of documentation polishing.
    
    o Made some minor constness fixes.  Thanks to Erwin van Eijk
      for this patch.

    o Made some warning fixes for GCC 4.0.  Not all warnings are
      fixed, because some of the needed changes would break the ABI.
      Thanks to Chris Frey for this patch.

    o Added lib/Doxyfile to distribution.
    

1.7.34, 2005.04.30 (r573)

    o Added a multiple-insert method for Query, which lets you insert
      a range of records from an STL container (or the whole thing,
      if you like) in a single SQL query.  This is faster, and it
      reduces coding errors due to less repetition.  Thanks to Mark
      Meredino for the patch.

    o Reference and user manual now get rebuilt automatically when
      required.  (E.g. on 'make dist', or explicitly now through 'make
      docs'.)

    o Made it easier to change the maximum number of SSQLS data members
      in generated custom-macros.h file.  It used to be hard-coded in
      several places in lib/custom.pl; now it's a variable at the top of
      the file.

    o Changed default SSQLS data member limit to 25, which is what it
      has been documented as for a long time now.  It was actually 26
      within custom.pl.

    o Fixed a regression in previous version.

    o Trimmed some fat from the distribution packages.

    o Some more small doucmentation improvements.


1.7.33, 2005.04.29 (r555)

    o Worked around an overloaded operator lookup bug in VC++ 7.1
      that caused SSQLS insert, replace and update queries to get
      mangled.  (Symptom was that custom2 and custom3 examples didn't
      work right.)  Thanks to Mark Meredino for digging up the
      following, which explains the problem and gives the solution:

      http://groups-beta.google.com/group/microsoft.public.vc.stl/browse_thread/thread/9a68d84644e64f15

    o Some VC++ warning fixes.

    o Major documentation improvements:
    
        o Using DocBook for user manual and Doxygen for reference
          manual.  The former now references the latter where
          useful.

        o Split out HACKERS and CREDITS files from main README,
          and improved remaining bits of README.

        o Moved the text from the old v1.7.9 LaTeX-based
          documentation over into the new systems, and reworked
          it to more closely resemble English.

        o Added a lot of new material to documentation, and
          simplified a lot of what already existed.

        o Documentation is now being built in HTML and PDF forms.

    o ebuild file updated to take advantage of recent configure script
      features.  Thanks to Chris Frey for this patch.



1.7.32, 2005.03.10 (r479)

    o Example building may now be skipped with --disable-examples
      configure script flag.

    o Changed stock items added in resetdb.  One is now UTF-8 encoded,
      to show that basic use of Unicode with MySQL++ is easy, yet not
      foolproof.  (See formatting of table on systems where cout isn't
      UTF-8 aware!)  Other stock items now follow a theme, for your
      amusement.  :)

    o custom3 example now changes UTF-8 item's name to the 7-bit ASCII
      equivalent.  Previously, this example would fix a spelling error
      in the table.

    o resetdb example now says 'why' when it is unable to create the
      sample database.

    o Small formatting change to print_stock_table(), used by several
      examples.

    o Was issuing a VC++-specific warning-disable pragma when built by
      any Windows compiler.  Fixed.
    

1.7.31, 2005.03.05 (r462) The "Inevitable Point-one Followup" release

    o Check for threads support must now be explicitly requested via
      configure script's new --enable-thread-check flag.

    o Fix for contacting MySQL server on a nonstandard port number.
      Thanks to Chris Frey for this patch.

    o Example programs using standard command line format now accept a
      fourth optional parameter, a port number for the server.  Thanks
      to Chris Frey for this patch.

    o One more g++ 3.4 pedantic warning fix by Chris Frey.

    o Exception handling in resetdb is no longer nested, because you'd
      get a segfault on some systems when an exception was thrown from
      one of the inner try blocks.

    o Improvements to Connection class's handling of locking mechanism.
      Concept based on patches by Rongjun Mu.

    o Implemented the declared-but-never-defined Query::lock().  Thanks
      to Rongjun Mu for this patch.
    
    o Cleaned up some unclear if/else blocks in connection.cpp by
      adding explicit braces, correct indenting and putting normal
      code path in the if side instead of the else.


1.7.30, 2005.02.28 (r443) The "Power of Round Numbers" release

    o bootstrap script now accepts a 'pedantic' argument, which sets a
      bunch of CFLAGS that make g++ very picky about the code it
      accepts without warnings.
      
    o Fixed a bunch of things that generated warnings with g++ in
      pedantic mode. Only two warnings remain, having to do with
      floating point comparisons.  (See Wishlist for plans on how to
      deal with these.)  Thanks to Chris Frey for this patch.

    o Split long tests out of configure.in into M4 files in new config
      subdir.  This makes configure.in easier to read.

    o Added preliminary thread support.  Currently, this just means that
      we detect the required compiler and linker thread flags, and link
      against the proper thread-safe libraries.  THERE MAY BE
      UN-THREAD-SAFE CODE IN MYSQL++ STILL!

    o Standard C++ exceptions are the default now.  Old pre-Standard
      exception stuff removed.

    o Row::lookup_by_name() will throw the new BadFieldName exception if
      you pass a bad field name.  Thanks for this patch to Chris Frey.

    o Row::operator[] will throw a Standard C++ out of bounds exception
      by way of std::vector::at() if you pass it a bad index.  Thanks
      for this patch to Chris Frey.

    o Setting Connection::is_connected flag to false on close().
      Previously, is_connected() would continue to return true after
      close() was called.

    o All number-to-string conversion ctors in SQLString class now use
      ostringstream to do the conversion.  Previously, we used
      snprintf(), which isn't available on all systems.  Also, we used a
      C99 format specifier for the "long long" conversion, which is also
      not available on all systems.  This new ostringstream code should
      be platform-independent, finally.


1.7.28, 2005.02.04 (r403)

    o --with-mysql* flags to configure script now try the given
      directory explicitly, and only if that fails do they try
      variations, like tacking '/lib' and such onto it to try and find
      the MySQL includes and libraries.  Thanks to Matthew Walton for
      the patch.

    o Finally removed sql_quote.h's dependence on custom.h, by moving
      the one definition it needed from custom.h to deps.h.  This will
      help portability to compilers that can't handle the SSQLS macros,
      by making that part of the library truly optional.


1.7.27, 2005.01.12 (r395)

    o configure check for libmysqlclient now halts configuration if the
      library isn't found.  Previously, it would just be flagged as
      missing, and MySQL++ would fail to build.

    o Added sql_string.cpp to VC++ and BCBuilder project files.

    o Removed Totte Karlsson's 'populate' example, which never made it
      into the distribution anyway.

    o Removed last vestiges of 'dummy.cpp'.

    o Renamed *.cc to *.cpp in BCBuilder project files.

    o Worked around a BCBuilder C++ syntax processing bug in row.h.


1.7.26, 2004.12.17 (r382)

    o Moved all of the SQLString definitions out of the header and into
      a new .cpp file, reformatted it all, and made the integer
      conversion functions use snprintf() or _snprintf() instead of
      sprintf().  Also, widened some of the buffers for 64-bit systems.

    o Using quoted #include form for internal library headers, to avoid
      some problems with file name clashes.  (The headers should still
      be installed in their own separate directory for best results,
      however.)  Thanks to Chris Frey and Evan Wies for the patch and
      the discussion that lead to it.

    o Removed unnecessary semicolons on namespace block closures.
      Thanks to Evan Wies for this patch.

    o Fixed namespace handling in the legacy headers mysql++.hh and
      sqlplus.hh.  Thanks to Chris Frey for this patch.

    o #including iostream instead of ostream in lib/null.h for
      broader C++ compatibility.  (This may allow MySQL++ to work on GCC
      2.95.2 again, but this is unconfirmed.)

    o Detecting proper mysql_shutdown() argument handling automatically
      in platform.h for the Windows compiler case instead of making the
      user edit the file.  Thanks to Evan Wies for this patch.
    
    o Fixed examples/Makefile.simple to use new *.cpp file naming.

    o Fix to Gentoo ebuild file's exception configure switch handling.
      Thanks to Chris Frey for this patch.

    o Rebuilding lib/custom*.h intelligently now, to avoid unnecessary
      recompiles after running bootstrap script.


1.7.25, 2004.12.09 (r360)

    o Yet more fixes to the --with-mysql-lib and --with-mysql-include
      flags.

    o Added DLLEXPORT stuff to platform.h, hopefully so that someone
      can figure out how to make VC++ make a DLL version of MySQL++.

    o Renamed *.cc to *.cpp.

    o Made 'set -> myset' change in VC++ project files.

    o Some style changes (mostly whitespace) in header files.


1.7.24, 2004.12.08 (r343)

    o Fixed the --with-mysql-lib and --with-mysql-include flags'
      behavior, and extended their search ability to handle one other
      common case.  (Fixed by Steve Roberts)

    o Fixes to put freestanding functions in namespace mysqlpp.  (They
      weren't in the namespace, while all the class member functions
      were.)  This required bumping the ABI version number to 4.
      
    o Renamed set module to myset, to avoid conflicts with Standard C++
      Library's set.h when MySQL++ headers were installed into one of
      the standard system include directories.

    o Renamed all the idempotency guards to make them consistent in
      style and unique to MySQL++.

    o Reformatted all of lib/*.cc.


1.7.23, 2004.11.20 (r333)

    o Query::reset() now empties the stored query string.  If you
      subsequently stored a longer query in the object, you'd overwrite
      the previous query, but otherwise the longer part of the previous
      one would stick out past the new query.

    o We now look to the NO_LONG_LONGS macro only to decide whether to
      fake 64-bit integer support using 32-bit integers.

    o 64-bit integer support under Visual C++ may be working now, using
      that platform's __int64_t type.  This has not been tested.

    o Removed 64-bit integer support for Codewarrior on Mac OS 9 and
      earlier.  OS X uses GCC, so it requires no special support.

    o Added MinGW detection in platform.h.
    
    o If you pass a flag (-X) to the examples that take the standard
      parameters (resetdb, simple1, etc.), it prints a usage message.
    
    o Better error handling in resetdb example, where errors are the
      most critical.  (If that one runs without errors, the others
      probably will, too, and you have to run that one first.)

    o resetdb now reports success, rather than succeeding silently.

    o Removed the code in sample1 example that duplicated util module's
      print_stock_table(), and called that function instead.

    o Moved the preview() calls in the example programs to before the
      query execution calls, because execution modifies the query.

    o All examples that take the standard command line parameters now 
      exit when connect_to_db() fails in one of the ways that don't
      throw an exception, rather than bulling onward until the next
      MySQL database call fails because the connection isn't up.

    o dbinfo example now takes the standard command line parameters.

    o Much better output formatting in dbinfo example.

    o Calling reset() where appropriate in the various example programs.
      Before, the programs may have worked, but not for the right
      reason.  This lead some people to believe that calling reset()
      was not necessary.

    o Fixed an incorrect use of row["string"] in complic1 example.

    o Lots of code style improvements to the examples.

    o Some VC++ type warnings squished.  Some remain.
    

1.7.22, 2004.11.17 (r302)

    o Applied patches by Zahroof Mohammed to allow it to build under GCC
      3.4.2.  Tested on MinGW and Fedora Core 3 systems.

    o Removed all the forward declarations in defs.h, and added
      forward declarations where necessary in individual header files.
      #including defs.h in fewer locations as a result.

    o Legacy headers sqlplus.hh and mysql++.hh now declare they are
      using namespace mysqlpp, to allow old code to compile against the
      new library without changes.

    o Removed query_reset parameter from several class Query member
      functions.  In the implementation, these parameters were always
      overridden!  No sense pretending that we pay attention to these
      parameters.  This changes the ABI version to 3.

    o #including custom.h in sql_query.h again...it's necessary on GCC
      3.4.
    
    o bootstrap script runs lib/config.pl after configure.  This is
      just a nicety for those running in 'maintainer mode'.


1.7.21, 2004.11.05 (r273)

    o Generating a main mysql++ RPM containing just the library files
      and basic documentation, and the -devel package containing
      everything else.

    o Devel package contains examples now, along with a new Makefile
      that uses the system include and library files, rather than the
      automake-based Makefile.am we currently have which uses the files
      in the mysql++ source directory.

    o Renamed sqlplusint subdirectory in the package to lib.

    o Removed the obsolete lib/README file.

    o lib/sql_query.h no longer #includes custom.h, simplifying
      build-time dependencies and shortening compile times.


1.7.20, 2004.11.03 (r258)

    o Collapsed all numbered *.hh headers into a single *.h file.  For
      example, the contents of row1.hh, row2.hh and row3.hh are now in
      row.h.

    o While doing the previous change, broke several circular
      dependencies.  (The numbered file scheme was probably partly done
      to avoid this problem.)  The practical upshot of most of these
      changes is that some functions are no longer inline.

    o Removed define_short.hh and everything associated with it.  The
      library now uses the short names exclusively (e.g. Row instead of
      MysqlRow).

    o Put all definitions into namespace mysqlpp.  For most programs,
      simply adding a 'using namespace mysqlpp' near the top of the
      program will suffice to convert to this version.

    o Once again, the main include file was renamed, this time to
      mysql++.h.  Hopefully this is the last renaming!

    o mysql++.hh still exists.  It emits a compiler warning that the
      file is obsolete, then it #includes mysql++.h for you.

    o sqlplus.hh is back, being a copy of the new mysql++.hh.  Both of
      these files may go away at any time.  They exist simply to help
      people transition to the new file naming scheme.

    o Renamed mysql++-windows.hh to platform.h, and added code to it to
      handle #inclusion of config.h on autotools-based systems
      intelligently.  This fixes the config.h error when building under
      Visual C++.

    o There is now only one place where conditional inclusion of
      winsock.h happens: platform.h.

    o Beautified the example programs.


1.7.19, 2004.10.25 (r186)

    o Fixed an infinite loop in the query mechanism resulting from the
      strstream change in the previous version.  There is an overloaded
      set of str() member functions that weren't a problem when query
      objects were based on strstream.
     
    o Query mechanism had a bunch of const-incorrectness: there were
      several function parameters and functions that were const for
      the convenience of other parts of the code, but within these
      functions the constness was const_cast away!  This was evil
      and wrong; now there are fewer const promises, and only one is
      still quietly broken within the code.  (It's in the SQLQuery
      copy ctor implementation; it should be harmless.)

    o Removed operator=() in Query and SQLQuery classes.  It cannot take
      a const argument for the same reason we have to cast away const
      in the SQLQuery copy ctor.  It's tolerable to do this in the copy
      ctor, but intolerable in an operator.  Since the copy ctor is good
      enough for all code within the library and within my own code, I'm
      removing the operator.

    o Above changes required bumping the ABI to version 2.

    o Visual C++ projects now look for MySQL build files in c:\mysql,
      since that's the default install location.  (Previously, it was
      c:\program files\mysql.)


1.7.18, 2004.10.01 (r177)

    o Changed all the strstream (and friends) stuff to stringstream type
      classes.  Let there be much rejoicing.

    o Query object now lets you use store() even when the SQL query
      cannot return a result, such as a DROP TABLE command.  This is
      useful for sending arbitrary SQL to the server.  Thanks to
      Jose Mortensen for the patch.

    o Quote fix in configure.in, thanks to David Sward.

    o Renamed undef_short file to undef_short.hh.

    o Gentoo ebuild file is actually being shipped with the tarball,
      instead of just sitting in my private CVS tree since 1.7.14 was
      current.  Ooops....


1.7.17, 2004.09.16 (r170)

    o Reverted one of the VC++ warning fix changes from 1.7.16 that
      caused crashes on Linux.

    o Added a configure test that conditionally adds the extra 'level'
      parameter to mysql_shutdown() that was added in MySQL 4.1.3 and
      5.0.1.


1.7.16, 2004.09.13 (r160)

    o Building VC++ version with DLL version of C runtime libraries, and
      at warning level 3 with no warnings emitted.

    o VC++ build no longer attempts to fake "long long" support.  See
      the Wishlist for further thoughts on this.


1.7.15, 2004.09.02 (r144)

    o Renamed Configure file to common.am, to avoid file name conflict
      with configure script on case-sensitive file systems.

    o Added ebuild file and ebuild target to top-level Makefile for
      Gentoo systems.  Thanks to Chris Frey for this.

    o Small efficiency improvements to BadQuery exception handling.
      Initial idea by Chris Frey, improvements by Warren Young.


1.7.14, 2004.08.26 (r130)

    o Builds with Visual C++ 7.1.

    o Fixed a bug in custom macro generation that caused problems with
      GCC 3.4.  (X_cus_value_list ctor definition was broken.)


1.7.13, 2004.08.23 (r92)

    o Removed USL CC support.  (System V stock system compiler.)  Use
      GCC on these platforms instead.

    o Added examples/README, explaining how to use the examples, and
      what they all do.

    o Most of the example programs now accept command line arguments for
      host name, user name and password, like resetdb does.

    o Renamed sinisa_ex example to dbinfo.

    o Several Standard C++ syntax fixes to quash errors emitted by
      GCC 3.4 and Borland C++ Builder 6.  Thanks to Steffen Schumacher
      and Totte Karlsson for their testing and help with these.

    o Added proper #includes for BCBuilder, plus project files for same.
      Thanks to Totte Karlsson for these.


1.7.12, 2004.08.19 (r63)

    o Many Standard C++ fixes, most from the GCC 3.4 patch by
      Rune Kleveland.

    o Added Wishlist file to distribution.

    o Fixed a problem in the bootstrap script that caused complaints
      from the autotools on some systems.

    o RPM building is working properly now.

    o Fixed the idempotency guard in datetime1.hh.


1.7.11, 2004.08.17 (r50)

    o Renamed mysql++, defs and define_short files, adding .hh to the
      end of each.  (They're header files!)  This shouldn't impact
      library users, since these are hopefully used internal to the
      library only.

    o Removed sqlplus.hh file.  Use mysql++.hh instead.
    
    o Added mysql++.spec, extracted from contributed 1.7.9 source RPM, 
      and updated it significantly.  Also, added an 'rpm' target to
      Makefile.am to automate the process of building RPMs.

    o Added bootstrap and LGPL files to distribution tarball.

    o Added pre-1.7.10 history to this file.

    o Removed .version file.  Apparently it's something required by old
      versions of libtool.


1.7.10, 2004.08.16 (r27)

    o Maintenance taken over by Warren Young (mysqlpp at etr dash usa
      dot com.) See http://lists.mysql.com/plusplus/3326 for details.

    o Applied many of the GCC 3.x patches submitted for 1.7.9 over
      the years.  This allows it to build on everything from 3.0 to
      3.3.3, at least.  Because so many patches are rolled up in one
      big jump, it's difficult to describe all the changes and where
      they came from.  Mostly they're Standard C++ fixes, as GCC
      has become more strict in the source code that it will accept.

    o MysqlRow used to overload operator[] for string types as well as
      integers so you could look up a field by its name, rather than by
      its index.  GCC 3.3 says this is illegal C++ due to ambiguities in
      resolving which overload should be used in various situations.
      operator[] is now overloaded only for one integer type, and a
      new member function lookup_by_name() was added to maintain the old
      by-field-name functionality.

    o Fixed another operator overloading problem in SSQLS macro
      generation with GCC 3.3.

    o The _table member of SSQLS-defined structures is now const char*,
      so you can assign to it from a const char* string.

    o Got autoconf/automake build system working with current versions
      of those tools again.  Removed the generated autotools files from
      CVS.

    o Renamed library file from libsqlplus to libmysqlpp.


1.7.9 (May 1 2001) Sinisa Milivojevic <sinisa@mysql.com>

    * Fixed a serious bug in Connection constructor when reading MySQL
    * options
    * Improved copy constructor and some other methods in Result /
    * ResUse
    * Many other minor improvements
    * Produced a complete manual with chapter 5 included
    * Updated documentation, including a Postscript format

1.7.8 (November 14 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * Introduced a new, standard way of dealing with C++ exceptions.
    * MySQL++ now supports two different methods of tracing exceptions.
    * One is by the fixed type (the old one) and one is standard C++
    * type by the usage of what() method. A choice of methods has to be
    * done in building a library. If configure script is run with
    * -enable-exception option , then new method will be used. If no
    * option is provided, or -disable-exception is used, old MySQL++
    * exceptions will be enforced. This innovation is a contribution of
    * Mr. Ben Johnson <ben@blarg.net>
    * MySQL++ now automatically reads at connection all standard MySQL
    * configuration files
    * Fixed a bug in sql_query::parse to enable it to parse more then 99
    * char's
    * Added an optional client flag in connect, which will enable usage
    * of this option, e.g. for getting matched and not just affected
    * rows. This change does not require any changes in existing
    * programs
    * Fixed some smaller bugs
    * Added better handling of NULL's. Programmers will get a NULL
    * string in result set and should use is_null() method in ColData to
    * check if value is NULL
    * Further improved configuration
    * Updated documentation, including a Postscript format

1.7.6 (September 22 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This release contains some C++ coherency improvements and scripts
    * enhacements
    * result_id() is made available to programmers to fetch
    * LAST_INSERT_ID() value
    * Connection constroctur ambiguity resolved, thanks to marc@mit.edu
    * Improved cnnfigure for better finding out MySQL libraries and
    * includes
    * Updated documentation, including a Postscript format

1.7.5 (July 30 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This release has mainl bug fixes  and code improvements
    * A bug in FieldNames::init has been fixed, enabling a bug free
    * usage of this class with in what ever a mixture of cases that is
    * required
    * Changed behaviour of ResUse, Result and Row classes, so that they
    * could be re-used as much as necessary, without any memory leaks,
    * nor with any re-initializations necessary
    * Fixed all potential leaks that could have been caused by usage of
    * delete instead of delete[] after memory has been allocated with
    * new[]
    * Deleted all unused classes and macros. This led to a reduction of
    * library size to one half of the original size. This has
    * furthermore brought improvements in compilation speed
    * Moved all string manipulation from system libraries to
    * libmysqlclient, thus enabling uniformity of code and usage of 64
    * bit integers on all platforms, including Windows, without
    * reverting to conditional compilation. This changes now requires
    * usage of mysql 3.23 client libraries, as mandatory
    * Changed examples to reflect above changes
    * Configuration scripts have been largely changed and further
    * changes shall appear in consecutive sub-releases. This changes
    * have been done and shall be done by our MySQL developer Thimble
    * Smith <tim@mysql.com>
    * Changed README, TODO and text version of manual. Other versions of
    * manual have not been updated
    * Fixed .version ``bug''. This is only partially fixed and version
    * remains 1.7.0 due to some problems in current versions of libtool.
    * This shall be finally fixed in a near future
    * Several smaller fixes and improvements
    * Added build.sh script to point to the correct procedure of
    * building of this library. Edit it to add configure options of your
    * choice

1.7 (May17 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This is mainly a release dealing with bug fixes, consistency
    * improvements and easier configure on some platforms
    * A bug in fetch_row() method of ResUse class has been fixed. Beside
    * changes that existed in a distributed patch, some additional error
    * checking has been introduced
    * A bug in escape manipulator has been fixed that could cause an
    * error if all characters had to be escaped
    * An inconsistency in column indexing has been fixed. Before this
    * version, column names in row indexing with strings, i.e.
    * row[<string>] , has been case sensitive, which was inconsistent
    * with MySQL server handling of column names
    * An inconsistency in conversion from strings to integers or floats
    * has been fixed. In prior version a space found in data would cause
    * a BadConversion exception. This has been fixed, but 100%
    * consistency with MySQL server has not been targeted, so that other
    * non-numeric characters in data will still cause BadConversion
    * exception or error. As this API is used in applications, users
    * should provide feedback if full compatibility with MySQL server is
    * desired, in which case BadConversion exception or error would be
    * abolished in some of future versions
    * A new method in ColData class has been introduced. is_null()
    * method returns a boolean to denote if a column in a row is NULL.
    * Finally, as of this release, testing for NULL values is possible.
    * Those are columns with empty strings for which is_null() returns
    * true.
    * Some SPARC Solaris installations had C++ exception problems with
    * g++ 2.95.2 This was a bug that was fixed in GNU gcc, as from
    * release 2.95 19990728. This version was thoroughly tested and is
    * fully functional on SPARC Solaris 2.6 with the above version of
    * gcc.
    * A 'virtual destructor ' warning for Result class has been fixed
    * Several new functions for STL strings have been added. Those
    * functions (see string_util.hh) add some of the functionality
    * missing in existing STL libraries
    * Conversion for 64 bit integers on FreeBSD systems has been added.
    * On those systems _FIX_FOR_BSD_ should be defined in CXXFLAGS prior
    * to configuring. Complete conversion to the usage of functions for
    * integer conversion found in mysqlclient library is planned for one
    * of the next releases
    * A completely new, fully dynamic, dramatic and fully mutable result
    * set has been designed and will be implemented in some of 2.x
    * releases
    * Several smaller fixes and improvements, including defaulting
    * exceptions to true, instead of false, as of this version
    * An up-to-date and complete Postscript version of documentation is
    * included in this distribution
    * Large chunks of this manual are changed, as well as README and
    * TODO files.

1.6 (Feb 3 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This is a major release as it includes new features and major
    * rewrites
    * Automatic quoting and escaping with streams. It works
    * automatically , depending on the column type. It will work with <<
    * on all ostream derived types. it is paricularly handy with query
    * objects and strstreams. Automatic quoting and escaping on cout,
    * cerr and clog stream objects is intentionally left out, as quoting
    * / escaping on those stream objects is not necessary. This feature
    * can be turned of by setting global boolean dont_quote_auto to
    * true.
    * Made some major changes in code, so that now execute method should
    * be used only with SSQL and template queries, while for all other
    * query execution of UPDATE's, INSERT's, DELETE's, new method exec()
    * should be used. It is also faster.
    * New method get_string is inroduced for easier handling / casting
    * ColData into C++ strings.
    * Major rewrite of entire code, which led to it's reduction and
    * speed improvement. This also led to removal of several source
    * files.
    * Handling of binary data is introduced. No application program
    * changes are required. One of new example programs demonstrates
    * handling of binary data
    * Three new example programs have been written and thoroughly
    * tested. Their intention is to solve some problems addressed by
    * MySQL users.
    * Thorough changes is Makefile system has been made
    * Better configuration scripts are written, thanks to D.Hawkins
    * <dhawkins@cdrgts.com>
    * Added several bug fixes
    * Changed Manual and Changelog

    * Added robustness in classes, so that e.g. same query and row
    * objects can be re-used
    * Changed sinisa_ex example to reflect and demonstrate this
    * stability
    * Changed Changelog and README
    * Few other bug fixes and small improvements and speed-ups

    * pointer_tracker
    * Corrected bug in example file fieldinf1
    * Finally fixed mysql_init in Connection constructor, which provided
    * much greater stability !
    * Added read and get options, so that clients, like mysqlgui can use
    * it
    * Changed Changelog and README
    * Many other bug fixes.

1.2 (Oct 15 1999) Sinisa Milivojevic <sinisa@mysql.com>

    * bugs are fixed
    * Corrected bugs in sql_query.cc regarding delete versus delete[]
    * and string length in manip.cc
    * Changed manual
    * Changed README
    * Many other smaller things

    * Added patches from Orion Poplawski <orion@bvt.com> to support the
    * UnixWare 7.0 compiler

.64.1.1a (Sep 27 1998)

    * Fixed several bugs that caused my library to fail to compile with
    * egcs 1.1. Hopefully it will still compile with egcs 1.0 however I
    * have not been able to test it with egcs 1.0.
    * Removed some problem causing debug output in sql++pretty.

.64.1a (Aug 1 1998)

    * Added an (almost) full guide to using Template Queries.
    * Fixed it so the SQLQuery will throw an exception when all the
    * template parameters are not provided.
    * Proofread and speedchecked the manual (it really needed it).
    * Other minor document fixes.

.64.0.1a (July 31 1998)

    * Reworked the Class Reference section a bit.
    * Minor document fixes
    * Added more examples for SSQLS.
    * Changed the syntax of equal_list for SSQLS from equal_list (cchar
    * *, Manip, cchar *) to (cchar *, cchar *, Manip).
    * Added set methods to SSQLS. These new methods do the same thing as
    * there corresponding constructors.
    * Added methods for creating a mysql_type_info from a C++ type_info.

.64.a (July 24 1998)

    * Changed the names of all the classes so they no longer have to
    * have Mysql in the begging of it. However if this creates a problem
    * you can define a macro to only use the old names instead.
    * The Specialized SQL Structures (formally known as Custom Mysql
    * Structures) changed from mysql_ to sql_.
    * Added the option of using exceptions thoughout the API.
    * ColData (formally known as MysqlStrings) will now throw an
    * exception if there is a problem in the conversion.
    * Added a null adapter.
    * Added Mutable Result Sets
    * Added a very basic runtime type identification for SQL types
    * Changed the document format from POD to LYX .
    * Am now using a modified version of Perceps to extract the class
    * information directly from the code to make my life easier.
    * Added an option of defining a macro to avoid using the automatic
    * conversion with binary operators.
    * Other small fixed I probully forgot to mentune.

.63.1.a

    * Added Custom Mysql Structures.
    * Fixed the Copy constructor of class Mysql
    * Started adding code so that class Mysql lets it children now when
    * it is leaving

.62.a (May 3 1998)

    * Added Template Queries
    * Created s separate SQLQuery object that is independent of an SQL
    * connection.
    * You no longer have to import the data for the test program as the
    * program creates the database and tables it needs.
    * Many small bug fixes.

.61.1.a (April 28 1998)

    * Cleaned up the example code in test.cc and included it in the
    * manual.
    * Added an interface layout plan to the manual.
    * Added a reverse iterator.
    * Fixed a bug with row.hh (It wasn't being included because of a
    * typo).

.61.0.a

    * Major interface changes. I warned you that the interface may
    * change while it is in pre-alpha state and I wasn't kidding.
    * Created a new and Separate Query Object. You can no longer execute
    * queries from the Mysql object instead you have to create a query
    * object with Mysql::query() and use it to execute queries.
    * Added the comparison operators to MysqlDate, MysqlTime and
    * MysqlDateTime. Fixed a few bugs in the MysqlDate... that effected
    * the stream output and the conversion of them to strings.
    * Reflected the MysqlDate... changes in the manual.
    * Added a new MysqlSet object and a bunch of functions for working
    * with mysql set strings.

    * compatibility Minor Manual fix.
    * Changed makefile to make it more compatible with Solaris (Thanks
    * Chris H)
    * Fixed bug in comparison functions so that they would compare in he
    * right direction.
    * Added some items to the to do list be sure to have a look.

Patches for any of these thoughtfully considered!  See the HACKERS file
for instructions on sending patches.


The items in the bug fix/maintenance section are the easiest to do
without breaking things, so if you're looking for a project....


Here's a meta-item that doesn't really fit into any of the categories
below: any time you must hand-roll some SQL code in your program,
consider whether it could be reduced to an API feature that would be
widely useful.  Patches or proposals of this sort are always welcome.


v2.1 Plan
---------

	This plan is not set in stone.	These are simply the features
	we want to try and tackle for the v2.1 release.

	Items in this plan may slip to a future release.  This
	typically happens when the proper solution is unclear,
	so the best way to prevent this is to get on the mailing
	list and help discuss it.  Or even better, provide a patch;
	we rarely reject working code outright.

	Items from the following sections may make it in, but if
	you don't help make that happen, this will just be on the
	whim of one of MySQL++'s developers.  Don't forget that it's
	possible to subclass yourself from the "MySQL++'s developers"
	base class.


	o Transaction support.	Create a "Transaction" class, an
	  object of which you create on the stack, giving it a
	  reference to the Connection object.  Transaction object's
	  ctor calls a function on the Connection object to start
	  a transaction set, and its dtor calls another function to
	  commit the transaction.  Also provide a "commit()" member
	  function, to commit before destruction.  This has a couple
	  of uses.  First, it's useful for avoiding exceptions coming
	  from ~Transaction(), if such a thing is possible.  Second,
	  sometimes it's inconvenient to wait until the end of a block
	  to commit the transaction, and adding artifical blocks is
	  somewhat ugly.

	o Add a configure script option to allow the new lock
	  mechanism to use platform mutexes via the Boost.Threads
	  library.

	  Mechanism must reflect these MySQL C API restrictions:

	  - Only one query executing at once per connection

	  - For "use" queries, Connection (and therefore Query) object must
	    remain locked until last row is consumed

	  - Safest to have one Connection per thread.  Rules for sharing:
	    http://dev.mysql.com/doc/mysql/en/threaded-clients.html

	  Need some way to call mysql_thread_init() and
	  mysql_thread_end() per thread.  Also, work in some way to
	  call mysql_thread_safe() automatically, perhaps the first
	  time through the function that calls mysql_thread_init().
	  If the C API library reports that it is not thread-safe,
	  report this to the caller, perhaps through an exception,
	  or simply by refusing to init more than one thread.

	o Currently, all overloads for Query's execute(), store()
	  and use() methods eventually call the const char*
	  version, which does the actual work of executing the query.
	  This rules out query strings with embedded nulls, as you're
	  likely to get with BLOB columns.  Also, it means MySQL++
	  must scan the string for length in a few places.  The C API
	  isn't limited in this way if you use mysql_real_query(),
	  but you need an accurate length value to call it.  We could
	  get that length with binary data if the end of the call
	  chain were a std::string overload, but we can't do that
	  easily because each of these functions has a version taking
	  a SQLString (a subclass of std:string) for template queries.

	  One way around this is to add a parallel set of functions
	  (e.g. do_execute(), or execute_(), or some such) that take
	  a single std::string, which are the new terminus of the call
	  chain.  Reimplement const char* versions in terms of these.

	  Another way is to rename the template query versions (e.g. to
	  execute_tq()) to avoid the overload conflict.  With that
	  done, we can use C API functions like mysql_real_query(),
	  which can take binary data.

	  Yet another way is to add a length parameter to the call
	  chain end functions.

	  And finally, we may be able to co-opt the first template
	  query version of each of these functions, as it takes a
	  single SQLString.

	o Date and time classes are pretty minimalistic; they could
	  be so much more powerful.  Some ideas:

	  - Add time_t conversion.

	  - Arithmetic features.  (See "Algorithms for Programmers"
	    by Binstock and Rex.)

	  - It may be possible to get some nice syntactic sugar,
	    such as a way to call SQL functions like NOW() when
	    inserting certain Date/Time objects into a Query stream.

	  Don't forget to write an example showing how to use these
	  new mechanisms.

	  It may be possible to find existing date and time classes
	  that can be extended, instead of reinventing the wheel.
	  Boost, perhaps?

	o When you create a Connection object with its default ctor and
	  don't .connect() it, several of its functions can fail to
	  work correctly.  ping(), for one, because the MYSQL handle
	  isn't initialized until the connection is established.
	  Decide how to cope: a) init the handle in all ctors; b)
	  throw ObjectNotInitialized when the library knows the
	  call will fail; or c) just return a failure code and hope
	  the user is checking it.  Could be a different answer for
	  each function.  Keep in mind the consequences for database-
	  independence here.

	o Build a forward iterator mechanism for ResUse.  Make it
	  general enough that you can use it with STL algorithms
	  like find_if().  Then make an example to demonstrate this
	  augmentation of SELECT.  Also, update usequery example
	  to use the iterator.	Tricky bit: how do we make it not
	  interfere with subclass Result's random-access iterator?

	o Write an example to demonstrate compare.h features, or throw
	  the header away.  It's not being used within the library.

	o Have resetdb create a second table containing a BLOB column
	  that load_file and cgi_image can use.  
	  
	  Rework load_image to take the standard command line
	  parameters, and load a JPEG or something into the BLOB table.
	  Include a suitable JPEG with the distribution.  (A cheesy
	  Photoshopped "MySQL++ Rocks!" thing should suffice.)

	  Rework cgi_image so that you can drop it into a cgi-image
	  directory and immediately use it to query the database and
	  return the image data in CGI format.

	o It may be possible to optimize the use of ColData in
	  the return from Row::operator[].  Currently, that operator
	  returns a temporary ColData object, which contains a
	  std::string buffer which is initialized by a const char*
	  pointer to data within the Row object.  Since the ColData
	  object is temporary, you currently must copy the data a
	  second time to store it when using Row::operator[].  If the
	  end user just wants a const char*, this double copy could
	  be prevented.  See http://lists.mysql.com/plusplus/4451
	  for the proposal.


Future Features
---------------

	These changes are planned for versions after v2.1.  If you
	need one of these changes to happen on some particular
	schedule, the best way to ensure it is to start coding and
	provide a patch!


	o Define operator<< for Fields, Row, ResUse, etc.  In other
	  words, there should be a way to get a user-readable version
	  of received data without a lot of code.  Perhaps use a CSV
	  output format, or a mysql(1) one (ASCII grid).

	o Abstract all uses of MySQL C API functions into a database
	  driver class with a generic interface.  This is a step
	  towards database-independence, without the parallel class
	  hierarchy required by the MySQL++ 1.7 design.  Also, it
	  will make it easier to make class Connection completely
	  friend-less.	Right now, the main reason it needs friends
	  is because these other classes make C API calls using its
	  private MYSQL data member.  The other reasons for it having
	  friends aren't nearly as compelling, so it wouldn't be
	  hard to justify redesigning Connection to eliminate these
	  final reasons.

	  While it would be easy to have just one global database
	  driver object, it's probably going to be necessary to have
	  one per Connection.  Consider what happens when you have one
	  program connected to two very different MySQL databases,
	  and you indirectly call C API functions that take MYSQL
	  parameters.  It's likely that those calls are supposed
	  to behave different, depending on the data in that MYSQL
	  object; for instance, different character encodings in the
	  selected databases.  So, there must somehow be a way to pass
	  the database driver's instance pointer down to all objects
	  that will need to use the driver.  A side benefit is that
	  a single program could talk to multiple different database
	  server types.  Imagine a program for importing data from
	  PostgreSQL and loading it into a MySQL table, for instance.

	o manip.cpp uses mysql_escape_string(), which doesn't take the
	  selected database's character set into account.  To do that,
	  you must use mysql_real_escape_string(), which differs
	  by taking a MYSQL instance as an additional parameter.
	  The problem is, Connection owns the relevant MYSQL instance,
	  and the manipulator functionality is implemented in global
	  functions (operator<<() and such) so they have no direct
	  access to the relevant Connection object.

	  The key question for all operator<<'s for manipulators
	  to ask is, "which Query object am I being inserted into?"
	  From there, you can look up the associated Connection object.

	  In some cases, this answer to the question is easy, because
	  the operator takes an ostream parameter, which can be
	  dynamically cast to Query.  From there, it's just a lookup
	  table problem.
	  
	  Other operator<<'s don't take an ostream, but they do take
	  a manipulator.  Right now, manipulators are just enum values,
	  but they could in fact be classes.  Classes can carry data,
	  so there may be a way to "bind" them to the appropriate
	  Connection object.  If not, then perhaps some other method
	  will pop out of the database driver class idea.  The driver
	  object may be able to look up a suitable Connection object
	  for the manipulators.

	o SSQLS structures include some static elements (_table and
	  names[]), which are defined within the macro.  If you
	  put an SSQLS declaration in a header file and #include
	  that from multiple locations, you get a multiply-defined
	  symbol warning.  Some ways to separate the definition from
	  the declaration:

		  o Give the SSQLS macros another parameter, to
		    suppress static definition.

		  o Put statics in a separate macro, which the
		    user must instantiate once in a .cpp file.
		    (Similar to the way MFC message maps work.)

		  o Put statics in a sub-macro, conditionally defined,
		    which SSQLS is implemented in terms of.  Define the
			condition macro in one module within your
			program.

		  o Redesign the SSQLS mechanism entirely.  Instead of
		    defining SSQLSes by instantiating macros, you could
		    declare the structure in, say, an XML format,
		    which could be tranformed (XSLT?  Perl + a DOM
		    parser?) into code very much like in the current
		    SSQLS macros, except that it would generate
		    separate .cpp and .h files for each structure.
		    In addition to solving the static member problem,
		    it would have other advantages, like side-stepping
		    the Borland C++ macro size limit.

	o Deprecate sql_create_basic_* ? They have less functionality
	  and they're no easier to use than sql_create and friends,
	  so why bother with them?  I suppose the code generated
	  is a bit smaller, but *really*....  Only possible saving
	  grace is if BC++ can compile them due to the macro code
	  being shorter.  They also don't have the static members,
	  mentioned in the previous item.

	o Consider whether some of the current boilerplate can be
	  made into a base class that all SSQLSes derive from.
	  This may have implications for some templates, like
	  Query::insert<T>...they might become regular member
	  functions, taking a reference to the base class.

	o MySQL++ handles automatic quoting and escaping differently
	  for cout and cerr than for Query streams.  This should
	  probably be simplified so that automatic quoting is only
	  done for Query streams.  No other stream type should be
	  treated specially.

	o Some field_list() functions use the do_nothing manipulator,
	  while others use the quote manipulator.  Need to pick one.
	  In the vast majority of cases, quoting won't be necessary,
	  so make that the default.  But, it should be possible to turn
	  it on, if needed.  If all uses of quoting are in template
	  code, this can be a #define, allowing different programs
	  built on the same system to get different quoting rules.
	  Otherwise, it will probably have to be a configure script
	  flag, which will "burn" the choice into the built binary.

	o User-settable floating-point comparison precisions?
	  Something like this: http://lists.mysql.com/plusplus/3984
	  As it currently stands, sql_cmp(double,double) is foolish.
	  One shouldn't do exact equality comparison on floating
	  point values.

	o Consider using MySQL C API enum constants in
	  mysql_type_info::types definition instead of hard-coded
	  values.  This could potentially break a lot of
	  infrastructure, though, so do it only with care.


Bug Fix/Maintenance Items
-------------------------

	These items could happen in any version.


	o 64-bit integer support has been reported to work, but more
	  confirmation is wanted.

	o Template ListInsert in lib/myset.h isn't being used within the
	  library.  It could probably be used in place of SetInsert
	  in the same file, which things like type_info.h do use now,
	  but it isn't clear how one would go about doing that without
	  changing the library code.  Document it or throw it away.

/// \file noexceptions.h

/// \brief Declares interface that allows exceptions to be optional
///
/// A class may inherit from OptionalExceptions, which will add to it
/// a mechanism by which a user can tell objects of that class to
/// suppress exceptions.  (They are enabled by default.)  This module
/// also declares a NoExceptions class, objects of which take a
/// reference to any class derived from OptionalExceptions.  The
/// NoExceptions constructor calls the method that disables exceptions,
/// and the destructor reverts them to the previous state.  One uses
/// the NoExceptions object within a scope to suppress exceptions in
/// that block, without having to worry about reverting the setting when
/// the block exits.

2.0.3, 2005.08.25 (r1060)

	o Visual C++ makemake system updated to build both debug and
	  release versions of library DLL.



	o Fixed bug in simple1 example that caused crashes on Windows.

	o Doing UTF-8 to ANSI text translation in simple examples now.


	o Previous two releases built libmysqlpp with wrong soname on
	  autotools-based systems.  Fixed.




2.0.2, 2005.08.18 (r1050)



	o Fixes to makemake system for cmd.exe.

	o Fixed the case where the system's C++ library includes an slist
	  implementation in namespace std.




2.0.1, 2005.08.17 (r1046)


	o Added new simple1 example, showing how to retrieve just one
	  column from a table.  Old simple1 is now called simple2, and
	  simple2 is likewise shifted to simple3.


	o Added custom6 example, showing how to do the same thing with
	  SSQLS.


	o Updated user manual to cover new examples.


	o Was accidentally shipping Subversion crap with tarball.  Fixed.




2.0.0, 2005.08.16 (r1031) The "Excess Hair Removal" release


	THIS IS NOT A DROP-IN REPLACEMENT FOR MySQL++ v1.7!


	At minimum, you will have to recompile your program against
	this library.  You may also have to make code changes.
	Please see the "Incompatible Library Changes" chapter of
	the user manual for a guide to migrating your code to this
	new version:








	http://tangentsoft.net/mysql++/doc/userman/html/breakages.html





	o The library's shared object file name (soname) scheme has
	  changed.  (This mainly affects POSIX systems.)
	  
	  The soname for the last 1.7.x releases of MySQL++ was
	  libmysqlpp.so.4, meaning the fourth version of the library's
	  application binary interface (ABI).  (The first ABI version
	  in this scheme was that provided by 1.7.9.)  MySQL++
	  2.0.0's soname is libmysqlpp.so.2.0.0.  Since the dynamic
	  linker setup on some systems will create a symlink to
	  that file called libmysqlpp.so.2, it's possible that this
	  library could be confused with that for MySQL++ 1.7.19
	  through .21, which also used this number.  Do not install
	  this library on a system which still has binaries linked
	  against that version of the library!




	  The new scheme is {ABI}.{feature}.{bug fix}.  That is,
	  the first number changes whenever we break the library's
	  binary interface; the second changes when adding features
	  that do not break the ABI; and the last changes when the
	  release contains only internal bug fixes.  This means
	  that we will probably end up with MySQL++ 3.0 and 4.0 at
	  some point, so there will be further soname conflicts.
	  Hopefully we can put these ABI changes off long enough
	  to avoid any real problems.

	o autoconf now installs headers into $prefix/include/mysql++,
	  instead of $prefix/include.  If you were using the
	  --includedir configure script option to get this behavior
	  before, you no longer need it.

	o Linux binary RPMs will henceforth include only the
	  libmysqlpp.so.X.Y.Z file, and create any short names
	  required, to allow multiple versions to be installed at
	  once.  Currently, you cannot install two MySQL++ library
	  RPMs at once, because they both have /usr/lib/libmysqlpp.so.X,
	  for instance.

	o Replaced the Visual C++ and Borland C++ project files with
	  a new "makemake" system, which creates Makefiles specific
	  to a particular toolchain.  This new mechanism also supports
	  MinGW and generic GCC-on-*ix.  This was done partly to reduce
	  the number of places we have to change when changing the
	  file names in MySQL++ or adding new ones, and partly so we're
	  not tied to one particular version of each of these tools.

	o VC++ Makefiles create a DLL version of the library only
	  now, so there's no excuse for LGPL violations now.
	  This same mechanism should make DLL builds under other
	  Windows compilers easy.

	o Added Connection::enable_ssl(), which enables encrypted
	  connections to the database server using SSL.

	o Connection::create_db() and drop_db() now return true on
	  success, not false.

	o Connection::create_db() and drop_db() use Query::exec()
	  now, for efficiency, rather than Query::execute().

	o Removed Connection::infoo().  Apparently just there to
	  save you from a typo when calling the info() method, since
	  it was a mere alias.

	o Renamed Connection::real_connect() to connect(), gave
	  several more of its parameters defaults, and removed old
	  connect() function.  Then changed user manual and examples
	  to use new APIs.

	o Replaced Connection::read_option() with new set_option()
	  mechanism.  The name change matches the method's purpose
	  better.  Functional changes are that it returns true on
	  success instead of 0, it supports a broader set of options
	  than read_option() did, and it enforces the correct option
	  argument type.

	o You can now call Connection::set_option() before the
	  connection is established, which will simply queue the option
	  request up until the connection comes up.  If you use this
	  feature, you should use exceptions, because that's the only
	  way an option setting failure can be signalled in this case.

	o Removed query-building functions (exec*(), store*(),
	  use()) from class Connection, and moved all the implementation
	  code to class Query.  Query no longer delegates the final
	  step of sending the query to the database server to
	  Connection().

	o Added Connection::enable_ssl(), for turning on SSL support on
	  a connection.

	o Extracted exception disabling mechanism out of the many
	  classes that had the feature into a new OptionalExceptions
	  base class, which all classes having this feature now
	  derive from.  Also, removed all per-method exception
	  handling flags.  Finally, added NoExceptions class.  With
	  all of these changes, there is now a common way to disable
	  exceptions with fine granularity on all objects that
	  support the feature.

	o All custom MySQL++ exceptions now derive from the new
	  Exceptions class.  This regularizes the exception interface
	  and allows you to use a single catch() block if you want.

	o The "throw exceptions" flag is passed from parent to child
	  in all situations now.  (Or if not, please report it as
	  a bug.) This fulfills a promise made in the v1.7.9 user
	  manual, with the cost being that some programs will see
	  new exceptions thrown that they're not expecting.

	o Added a bunch of new exception types: BadOption,
	  ConnectionFailed, DBSelectionFailed, EndOfResults,
	  EndOfResultSets, LockFailed, and ObjectNotInitialized.
	  Some of these replace the use of BadQuery, which in v1.7.x
	  was a kind of generic exception, thrown when something more
	  specific wasn't available.  Beware, this means that programs
	  may start crashing after recompiling them under v2.0 due to
	  uncaught exceptions, if they were only trying to catch BadQuery.

	  There are additional instances where the library will
	  throw new exceptions.  One is when calling a method that
	  forces the internals to use an out-of-bounds index on a
	  vector; previously, this would just make the program
	  likely to crash.  Another is that the library uses the
	  BadFieldName exception -- created in v1.7.30 -- in more
	  apropos situations.

	o Renamed SQLQueryNEParms to BadParamCount, to match naming
	  style of other concrete exception types.

	o Extracted lock()/unlock() functions from Connection and
	  Query classes into a new Lockable interface class.  Locking
	  is implemented in terms of a different class hierarchy, Lock,
	  which allows multiple locking strategies with a single ABI.

	o Removed ResUse::eof().  It's based on a deprecated MySQL
	  C API feature, and it isn't needed anyway.

	o Removed arrow operator (->) for iterator returned by Fields,
	  Result and Row containers.  It was inherently buggy, because
	  a correct arrow operator must return the address of an
	  object, but the underlying element access functions in these
	  classes (e.g. at()) return objects by value, of necessity.
	  Therefore, this operator could only return the address of
	  a temporary, which cannot be safely dereferenced.

	o Returned Row subscripting to something more like the
	  v1.7.9 scheme: there are two operator[] overloads, one for an
	  integer (field by index) and another for const char* (field
	  by name).  lookup_by_name() has been removed.  Because row[0]
	  is ambiguous again, added Row::at() (by analogy with STL
	  sequence containers), which always works.

	o Collapsed two of the Row::value_list*() overloads into
	  two other similar functions using default parameters.
	  This changes the API, but the removed functions aren't
	  used within the library, and I doubt they are used outside,
	  either.

	o Merged RowTemplate into Row.

	o Merged SQLQuery class into Query class.

	o Query is now derived from std::ostream instead of
	  std::stringstream, and we manage our own internal string
	  buffer.

	o Moved SQLParseElement and SQLQueryParms into their own
	  module, qparms.

	o Added multiple result set handling to Query.	MySQL 4.1
	  and higher allow you to give multiple SQL statements in a
	  single "store" call, which requires extensions to MySQL++
	  so you can iterate through the multiple result sets.	Also,
	  stored procedures in MySQL 5.0 reportedly return multiple
	  result sets.	Thanks for the initial patch go to Arnon Jalon;
	  I reworked it quite a bit.

	o Query::storein*() now supports more varieties of the
	  nonstandard slist comtainer.	(Singly-linked version of
	  STL std::list.)

	o Template query mechanism and user manual had several
	  mismatches.  Made manual match actual behavior, or
	  made library match documented behavior, as apropriate.
	  Initial patch by Jürgen MF Gleiss, with corrections and
	  enhancements by Warren Young.

	o Collapsed mysql_* date and time base classes' methods and
	  data into the subclasses.  Also, DateTime no longer derives
	  from Date and Time; you could get away with that in the
	  old hierarchy, but now it creates an inheritance diamond,
	  and allows unsupported concepts like comparing a Time to
	  a DateTime.

	o Removed "field name" form of Row::field_list().  It was
	  pretty much redundant -- if you have the field names, why
	  do you need a list of field names?

	o ColData can convert itself to bool now.  Thanks for this
	  patch go to Byrial Jensen.

	o Removed simp_list_b type; wasn't being used, and doesn't
	  look to be useful for end-user code.

	o Several methods that used to take objects by value now
	  do so by const reference, for efficiency.

	o Several variable and function renamings so that MySQL++
	  isn't needlessly tied to MySQL.  Even if we never make
	  the library work with other database servers, there's
	  little point in tying this library to MySQL blindly.

	o Renamed all private data members of MySQL++ classes to
	  have trailing underscores.

	o 'private' section follows 'public' section in all classes
	  now.

	o Removed mysql++.hh and sqlplus.hh backwards-compatibility
	  headers.

	o Added copy ctors to Date/Time classes so that they will
	  work in SSQLS under GCC 4.0.0.  Without these, the compiler
	  couldn't make the conversion from raw MySQL row data.

	o Fixed a bunch of GCC 4.0 pedantic warnings: added virtual
	  dtors to all base classes, calling base class ctors from leaf
	  classes, etc.

	o All warnings fixed under VC++ at warning level 3.  (Mostly
	  harmless signedness and integer conversion stuff.)

	o Updated LGPL license/copyright comments at the top of
	  several files to use FSF's new physical address.

	o Relicensed user manual under a close variant of the Linux
	  Documentation Project License, as it's designed for
	  documentation, which the LGPL is not.  Permission for this
	  received from Kevin Atkinson and MySQL AB.

	o Added ABI and API breakages chapter to user manual.  It
	  is basically a subset of this ChangeLog, with only the
	  information an end-user must know when migrating between
	  versions.

	o Reworked user manual's DocBook code quite a bit after
	  reading Bob Stayton's book "DocBook XSL" 3/e.  Better handling
	  of stylesheets, taking advantage of some superior DocBook
	  features, prettier output (especially the HTML version), etc.

	o Rewrote doc/userman/README to make it clearer how to get
	  started contributing to the user manual.  It's essentially a
	  "getting started with DocBook" guide now!

	o Lots of small text improvements to user and reference
	  manuals.  Aside from the obvious tracking of library changes,
	  made a bunch of minor style and clarity improvements.

	o Added CSS stylesheets for userman and refman to
	  make the HTML versions of each a) not ugly; and b) match
	  tangentsoft.net.  (Yes, some may say that these are incompatible
	  goals....)

	o Standardized exception handling code in the examples that
	  use it.

	o Fixed a potential memory leak due to exceptions thrown from
	  ResUse.  Thanks for this patch go to Chris Frey.

	o Using new "no exceptions" feature of library in simple1
	  example, so it is now truly simple.

	o simple1 example no longer depends as much on util module, so
	  that all of the important code is in one place.  Makes
	  learning MySQL++ a little less intimidating.

	o Added new simple2 and usequery examples, to demonstrate
	  the proper way to handle a "use" query, with exceptions
	  disabled, and not, respectively.  Added them to the user
	  manual, in the appropriate place.

	o Refactored the "print stock table" example functions
	  again, to make code using them clearer.

	o UTF-8 to UCS-2 handling in examples is now automatic on
	  Windows.

	o Removed debug code from Windows Unicode output examples
	  that slipped into previous release.

	o resetdb example is now clearer, and more robust in the
	  face of database errors.

	o Simplified connect_to_db() in examples' util module.

	o Added sample autoconf macro for finding MySQL++ libraries, for
	  people to use in their own autotools-based projects.

	o Lots and lots of minor cleanups not worth mentioning
	  individually...


1.7.40, 2005.05.26 (r719)

	o Multiple item form of insert() now works if you're using the
	  SQLQuery class, or its derivative, Query.  Thanks to Mark
	  Meredino for this patch.

	o Fixed a bug in const_string::compare(), in which MySQL++
	  would walk off the end of the shorter of the two strings.
	  All was well if the two were the same length.

	o ResUse::operator=() now fully updates the object, so it's more
	  like the behavior of the full ctor.

	o All source files now contain a license and copyright statement
	  somewhere within them.

	o Optimized mysql++.h a bit: it now #includes only the minimum set
	  of files required, and there is now an idempotency guard.
	  This improves compile times a smidge, but mainly it was
	  done to clean up the generated #include file graph in the
	  reference manual.  Before, it was a frightful tangle because
	  we #included everything except custom*.h.

	o Constness fix in MySQL++ date/time classes to avoid compiler
	  warnings with SSQLS.	Thanks to Wolfram Arnold for this patch.

	o Fixed some compiler warnings in custom*.h.  Thanks to Chris Frey
	  for this patch.

	o Added "Submitting Patches" and "Maintaining a Private CVS
	  Repository" sections to the HACKERS file.  Thanks to Chris
	  Frey for the source material for these sections.  The HACKERS
	  file was improved in several other ways at the same time.

	o PDF version of user manual no longer has links to the reference
	  manual.  They were ugly, and they were broken anyway due to the
	  way we move the PDFs after generating them.  If you want
	  interlinked manuals, use the HTML version.

	o PDF version of user manual now has hard page breaks between
	  chapters.

	o Removed complic1 example.  Wasn't pulling its own weight.
	  Everything it is supposed to demonstrate is shown in other
	  examples already.

	o Refactored print_stock_table() in examples/util module to be
	  four functions, and made all the examples use various of
	  these functions where appropriate.  Before, several of
	  the examples had one-off stock table printing code because
	  print_stock_table() wasn't exactly the right thing, for one
	  reason or another.  One practical problem with this is that
	  some of the examples missed out on the recent Unicode updates;
	  now such a change affects all examples the same way.

	o Since so many of the examples rely on the util module, the user
	  manual now covers it.  The simple1 example in the user manual
	  didn't make much sense before, in particular, because it's
	  really just a driver for the util module.

	o Added custom5 example.  It shows how to use the equal_list()
	  functionality of SSQLS.  Thanks to Chris Frey for the original
	  version of this program.  (I simplified it quite a bit after
	  accepting it.)

	o New user manual now covers the value_list(), equal_list() and
	  field_list() stuff that the old manual covered but which was
	  left out in previous versions of the new manaul.  Most of the
	  examples are the same, but the prose is almost completely new.
	  This new section includes the custom5 example.

	o Every declaration in MySQL++ is now documented in the reference
	  manual, or explicitly treated as "internal only".

	o Improved docs for MySQL++'s mechanism to map between MySQL
	  server types and C++ types.  Initial doc patch by Chris Frey,
	  which I greatly reworked.

	o Improved a lot of existing reference manual documentation while
	  adding the new stuff.

	o Expanded greatly on the exception handling discussion in the user
	  manual.

	o Added all-new "Quoting and Escaping" section to the user
	  manual's Tutorial chapter.  Moved some existing comments on
	  quoting and escaping around and added some new ones to other
	  sections as a result.

	o Added all-new "Handling SQL Nulls" section to the user manual's
	  Tutorial chapter.

	o Many improvements to the Overview section of the user manual.

	o Row::operator[] reference now explains the right and wrong way to
	  use the values it returns.  This is in response to a mailing list
	  post where someone was incorrectly using this feature and getting
	  a bunch of dangling pointers.

	o Updated Doxyfile so 1.3.19.1 parses it without warnings.  Still
	  works with versions back to 1.2.18, at least.  (These are
	  the versions shipped with Fedora Core 3 and Red Hat Linux 9,
	  respectively.)

	o Using a superior method to make Doxygen ignore certain sections
	  of the source code.  Between this change and the fact that
	  everything not so ignored is documented, Doxygen no longer
	  generates any warnings.

	o Lots of code style updates.  Everything should now be consistently
	  formatted.


1.7.35, 2005.05.05 (r601) The "Cinco de Mayo" release

	o Added a "how to use Unicode with MySQL++" chapter to the user
	  manual.  (Too bad "Cinco de Mayo" doesn't have any accented
	  characters.  That would be just _too_ precious.)

	o VC++ examples now use the Unicode Win32 APIs, so they can display
	  Unicode data from MySQL++.

	o Added an optional conversion function to examples/util.cpp to
	  handle the conversion from UTF-8 to UCS-2 on Win32.

	o Moved "brief history of MySQL++" from intro section of refman to
	  intro section of userman.

	o Lots of small bits of documentation polishing.
	
	o Made some minor constness fixes.  Thanks to Erwin van Eijk
	  for this patch.

	o Made some warning fixes for GCC 4.0.	Not all warnings are
	  fixed, because some of the needed changes would break the ABI.
	  Thanks to Chris Frey for this patch.

	o Added lib/Doxyfile to distribution.
	

1.7.34, 2005.04.30 (r573)

	o Added a multiple-insert method for Query, which lets you insert
	  a range of records from an STL container (or the whole thing,
	  if you like) in a single SQL query.  This is faster, and it
	  reduces coding errors due to less repetition.  Thanks to Mark
	  Meredino for the patch.

	o Reference and user manual now get rebuilt automatically when
	  required.  (E.g. on 'make dist', or explicitly now through 'make
	  docs'.)

	o Made it easier to change the maximum number of SSQLS data members
	  in generated custom-macros.h file.  It used to be hard-coded in
	  several places in lib/custom.pl; now it's a variable at the top of
	  the file.

	o Changed default SSQLS data member limit to 25, which is what it
	  has been documented as for a long time now.  It was actually 26
	  within custom.pl.

	o Fixed a regression in previous version.

	o Trimmed some fat from the distribution packages.

	o Some more small doucmentation improvements.


1.7.33, 2005.04.29 (r555)

	o Worked around an overloaded operator lookup bug in VC++ 7.1
	  that caused SSQLS insert, replace and update queries to get
	  mangled.  (Symptom was that custom2 and custom3 examples didn't
	  work right.)  Thanks to Mark Meredino for digging up the
	  following, which explains the problem and gives the solution:

	  http://groups-beta.google.com/group/microsoft.public.vc.stl/browse_thread/thread/9a68d84644e64f15

	o Some VC++ warning fixes.

	o Major documentation improvements:
	
		o Using DocBook for user manual and Doxygen for reference
		  manual.  The former now references the latter where
		  useful.

		o Split out HACKERS and CREDITS files from main README,
		  and improved remaining bits of README.

		o Moved the text from the old v1.7.9 LaTeX-based
		  documentation over into the new systems, and reworked
		  it to more closely resemble English.

		o Added a lot of new material to documentation, and
		  simplified a lot of what already existed.

		o Documentation is now being built in HTML and PDF forms.

	o ebuild file updated to take advantage of recent configure script
	  features.  Thanks to Chris Frey for this patch.



1.7.32, 2005.03.10 (r479)

	o Example building may now be skipped with --disable-examples
	  configure script flag.

	o Changed stock items added in resetdb.  One is now UTF-8 encoded,
	  to show that basic use of Unicode with MySQL++ is easy, yet not
	  foolproof.  (See formatting of table on systems where cout isn't
	  UTF-8 aware!)  Other stock items now follow a theme, for your
	  amusement.  :)

	o custom3 example now changes UTF-8 item's name to the 7-bit ASCII
	  equivalent.  Previously, this example would fix a spelling error
	  in the table.

	o resetdb example now says 'why' when it is unable to create the
	  sample database.

	o Small formatting change to print_stock_table(), used by several
	  examples.

	o Was issuing a VC++-specific warning-disable pragma when built by
	  any Windows compiler.  Fixed.
	

1.7.31, 2005.03.05 (r462) The "Inevitable Point-one Followup" release

	o Check for threads support must now be explicitly requested via
	  configure script's new --enable-thread-check flag.

	o Fix for contacting MySQL server on a nonstandard port number.
	  Thanks to Chris Frey for this patch.

	o Example programs using standard command line format now accept a
	  fourth optional parameter, a port number for the server.  Thanks
	  to Chris Frey for this patch.

	o One more g++ 3.4 pedantic warning fix by Chris Frey.

	o Exception handling in resetdb is no longer nested, because you'd
	  get a segfault on some systems when an exception was thrown from
	  one of the inner try blocks.

	o Improvements to Connection class's handling of locking mechanism.
	  Concept based on patches by Rongjun Mu.

	o Implemented the declared-but-never-defined Query::lock().  Thanks
	  to Rongjun Mu for this patch.
	
	o Cleaned up some unclear if/else blocks in connection.cpp by
	  adding explicit braces, correct indenting and putting normal
	  code path in the if side instead of the else.


1.7.30, 2005.02.28 (r443) The "Power of Round Numbers" release

	o bootstrap script now accepts a 'pedantic' argument, which sets a
	  bunch of CFLAGS that make g++ very picky about the code it
	  accepts without warnings.
	  
	o Fixed a bunch of things that generated warnings with g++ in
	  pedantic mode. Only two warnings remain, having to do with
	  floating point comparisons.  (See Wishlist for plans on how to
	  deal with these.)  Thanks to Chris Frey for this patch.

	o Split long tests out of configure.in into M4 files in new config
	  subdir.  This makes configure.in easier to read.

	o Added preliminary thread support.  Currently, this just means that
	  we detect the required compiler and linker thread flags, and link
	  against the proper thread-safe libraries.  THERE MAY BE
	  UN-THREAD-SAFE CODE IN MYSQL++ STILL!

	o Standard C++ exceptions are the default now.  Old pre-Standard
	  exception stuff removed.

	o Row::lookup_by_name() will throw the new BadFieldName exception if
	  you pass a bad field name.  Thanks for this patch to Chris Frey.

	o Row::operator[] will throw a Standard C++ out of bounds exception
	  by way of std::vector::at() if you pass it a bad index.  Thanks
	  for this patch to Chris Frey.

	o Setting Connection::is_connected flag to false on close().
	  Previously, is_connected() would continue to return true after
	  close() was called.

	o All number-to-string conversion ctors in SQLString class now use
	  ostringstream to do the conversion.  Previously, we used
	  snprintf(), which isn't available on all systems.  Also, we used a
	  C99 format specifier for the "long long" conversion, which is also
	  not available on all systems.  This new ostringstream code should
	  be platform-independent, finally.


1.7.28, 2005.02.04 (r403)

	o --with-mysql* flags to configure script now try the given
	  directory explicitly, and only if that fails do they try
	  variations, like tacking '/lib' and such onto it to try and find
	  the MySQL includes and libraries.  Thanks to Matthew Walton for
	  the patch.

	o Finally removed sql_quote.h's dependence on custom.h, by moving
	  the one definition it needed from custom.h to deps.h.  This will
	  help portability to compilers that can't handle the SSQLS macros,
	  by making that part of the library truly optional.


1.7.27, 2005.01.12 (r395)

	o configure check for libmysqlclient now halts configuration if the
	  library isn't found.  Previously, it would just be flagged as
	  missing, and MySQL++ would fail to build.

	o Added sql_string.cpp to VC++ and BCBuilder project files.

	o Removed Totte Karlsson's 'populate' example, which never made it
	  into the distribution anyway.

	o Removed last vestiges of 'dummy.cpp'.

	o Renamed *.cc to *.cpp in BCBuilder project files.

	o Worked around a BCBuilder C++ syntax processing bug in row.h.


1.7.26, 2004.12.17 (r382)

	o Moved all of the SQLString definitions out of the header and into
	  a new .cpp file, reformatted it all, and made the integer
	  conversion functions use snprintf() or _snprintf() instead of
	  sprintf().  Also, widened some of the buffers for 64-bit systems.

	o Using quoted #include form for internal library headers, to avoid
	  some problems with file name clashes.  (The headers should still
	  be installed in their own separate directory for best results,
	  however.)  Thanks to Chris Frey and Evan Wies for the patch and
	  the discussion that lead to it.

	o Removed unnecessary semicolons on namespace block closures.
	  Thanks to Evan Wies for this patch.

	o Fixed namespace handling in the legacy headers mysql++.hh and
	  sqlplus.hh.  Thanks to Chris Frey for this patch.

	o #including iostream instead of ostream in lib/null.h for
	  broader C++ compatibility.  (This may allow MySQL++ to work on GCC
	  2.95.2 again, but this is unconfirmed.)

	o Detecting proper mysql_shutdown() argument handling automatically
	  in platform.h for the Windows compiler case instead of making the
	  user edit the file.  Thanks to Evan Wies for this patch.
	
	o Fixed examples/Makefile.simple to use new *.cpp file naming.

	o Fix to Gentoo ebuild file's exception configure switch handling.
	  Thanks to Chris Frey for this patch.

	o Rebuilding lib/custom*.h intelligently now, to avoid unnecessary
	  recompiles after running bootstrap script.


1.7.25, 2004.12.09 (r360)

	o Yet more fixes to the --with-mysql-lib and --with-mysql-include
	  flags.

	o Added DLLEXPORT stuff to platform.h, hopefully so that someone
	  can figure out how to make VC++ make a DLL version of MySQL++.

	o Renamed *.cc to *.cpp.

	o Made 'set -> myset' change in VC++ project files.

	o Some style changes (mostly whitespace) in header files.


1.7.24, 2004.12.08 (r343)

	o Fixed the --with-mysql-lib and --with-mysql-include flags'
	  behavior, and extended their search ability to handle one other
	  common case.  (Fixed by Steve Roberts)

	o Fixes to put freestanding functions in namespace mysqlpp.  (They
	  weren't in the namespace, while all the class member functions
	  were.)  This required bumping the ABI version number to 4.
	  
	o Renamed set module to myset, to avoid conflicts with Standard C++
	  Library's set.h when MySQL++ headers were installed into one of
	  the standard system include directories.

	o Renamed all the idempotency guards to make them consistent in
	  style and unique to MySQL++.

	o Reformatted all of lib/*.cc.


1.7.23, 2004.11.20 (r333)

	o Query::reset() now empties the stored query string.  If you
	  subsequently stored a longer query in the object, you'd overwrite
	  the previous query, but otherwise the longer part of the previous
	  one would stick out past the new query.

	o We now look to the NO_LONG_LONGS macro only to decide whether to
	  fake 64-bit integer support using 32-bit integers.

	o 64-bit integer support under Visual C++ may be working now, using
	  that platform's __int64_t type.  This has not been tested.

	o Removed 64-bit integer support for Codewarrior on Mac OS 9 and
	  earlier.  OS X uses GCC, so it requires no special support.

	o Added MinGW detection in platform.h.
	
	o If you pass a flag (-X) to the examples that take the standard
	  parameters (resetdb, simple1, etc.), it prints a usage message.
	
	o Better error handling in resetdb example, where errors are the
	  most critical.  (If that one runs without errors, the others
	  probably will, too, and you have to run that one first.)

	o resetdb now reports success, rather than succeeding silently.

	o Removed the code in sample1 example that duplicated util module's
	  print_stock_table(), and called that function instead.

	o Moved the preview() calls in the example programs to before the
	  query execution calls, because execution modifies the query.

	o All examples that take the standard command line parameters now 
	  exit when connect_to_db() fails in one of the ways that don't
	  throw an exception, rather than bulling onward until the next
	  MySQL database call fails because the connection isn't up.

	o dbinfo example now takes the standard command line parameters.

	o Much better output formatting in dbinfo example.

	o Calling reset() where appropriate in the various example programs.
	  Before, the programs may have worked, but not for the right
	  reason.  This lead some people to believe that calling reset()
	  was not necessary.

	o Fixed an incorrect use of row["string"] in complic1 example.

	o Lots of code style improvements to the examples.

	o Some VC++ type warnings squished.  Some remain.
	

1.7.22, 2004.11.17 (r302)

	o Applied patches by Zahroof Mohammed to allow it to build under GCC
	  3.4.2.  Tested on MinGW and Fedora Core 3 systems.

	o Removed all the forward declarations in defs.h, and added
	  forward declarations where necessary in individual header files.
	  #including defs.h in fewer locations as a result.

	o Legacy headers sqlplus.hh and mysql++.hh now declare they are
	  using namespace mysqlpp, to allow old code to compile against the
	  new library without changes.

	o Removed query_reset parameter from several class Query member
	  functions.  In the implementation, these parameters were always
	  overridden!  No sense pretending that we pay attention to these
	  parameters.  This changes the ABI version to 3.

	o #including custom.h in sql_query.h again...it's necessary on GCC
	  3.4.
	
	o bootstrap script runs lib/config.pl after configure.  This is
	  just a nicety for those running in 'maintainer mode'.


1.7.21, 2004.11.05 (r273)

	o Generating a main mysql++ RPM containing just the library files
	  and basic documentation, and the -devel package containing
	  everything else.

	o Devel package contains examples now, along with a new Makefile
	  that uses the system include and library files, rather than the
	  automake-based Makefile.am we currently have which uses the files
	  in the mysql++ source directory.

	o Renamed sqlplusint subdirectory in the package to lib.

	o Removed the obsolete lib/README file.

	o lib/sql_query.h no longer #includes custom.h, simplifying
	  build-time dependencies and shortening compile times.


1.7.20, 2004.11.03 (r258)

	o Collapsed all numbered *.hh headers into a single *.h file.  For
	  example, the contents of row1.hh, row2.hh and row3.hh are now in
	  row.h.

	o While doing the previous change, broke several circular
	  dependencies.  (The numbered file scheme was probably partly done
	  to avoid this problem.)  The practical upshot of most of these
	  changes is that some functions are no longer inline.

	o Removed define_short.hh and everything associated with it.  The
	  library now uses the short names exclusively (e.g. Row instead of
	  MysqlRow).

	o Put all definitions into namespace mysqlpp.  For most programs,
	  simply adding a 'using namespace mysqlpp' near the top of the
	  program will suffice to convert to this version.

	o Once again, the main include file was renamed, this time to
	  mysql++.h.  Hopefully this is the last renaming!

	o mysql++.hh still exists.  It emits a compiler warning that the
	  file is obsolete, then it #includes mysql++.h for you.

	o sqlplus.hh is back, being a copy of the new mysql++.hh.  Both of
	  these files may go away at any time.  They exist simply to help
	  people transition to the new file naming scheme.

	o Renamed mysql++-windows.hh to platform.h, and added code to it to
	  handle #inclusion of config.h on autotools-based systems
	  intelligently.  This fixes the config.h error when building under
	  Visual C++.

	o There is now only one place where conditional inclusion of
	  winsock.h happens: platform.h.

	o Beautified the example programs.


1.7.19, 2004.10.25 (r186)

	o Fixed an infinite loop in the query mechanism resulting from the
	  strstream change in the previous version.  There is an overloaded
	  set of str() member functions that weren't a problem when query
	  objects were based on strstream.
	 
	o Query mechanism had a bunch of const-incorrectness: there were
	  several function parameters and functions that were const for
	  the convenience of other parts of the code, but within these
	  functions the constness was const_cast away!  This was evil
	  and wrong; now there are fewer const promises, and only one is
	  still quietly broken within the code.  (It's in the SQLQuery
	  copy ctor implementation; it should be harmless.)

	o Removed operator=() in Query and SQLQuery classes.  It cannot take
	  a const argument for the same reason we have to cast away const
	  in the SQLQuery copy ctor.  It's tolerable to do this in the copy
	  ctor, but intolerable in an operator.  Since the copy ctor is good
	  enough for all code within the library and within my own code, I'm
	  removing the operator.

	o Above changes required bumping the ABI to version 2.

	o Visual C++ projects now look for MySQL build files in c:\mysql,
	  since that's the default install location.  (Previously, it was
	  c:\program files\mysql.)


1.7.18, 2004.10.01 (r177)

	o Changed all the strstream (and friends) stuff to stringstream type
	  classes.  Let there be much rejoicing.

	o Query object now lets you use store() even when the SQL query
	  cannot return a result, such as a DROP TABLE command.  This is
	  useful for sending arbitrary SQL to the server.  Thanks to
	  Jose Mortensen for the patch.

	o Quote fix in configure.in, thanks to David Sward.

	o Renamed undef_short file to undef_short.hh.

	o Gentoo ebuild file is actually being shipped with the tarball,
	  instead of just sitting in my private CVS tree since 1.7.14 was
	  current.  Ooops....


1.7.17, 2004.09.16 (r170)

	o Reverted one of the VC++ warning fix changes from 1.7.16 that
	  caused crashes on Linux.

	o Added a configure test that conditionally adds the extra 'level'
	  parameter to mysql_shutdown() that was added in MySQL 4.1.3 and
	  5.0.1.


1.7.16, 2004.09.13 (r160)

	o Building VC++ version with DLL version of C runtime libraries, and
	  at warning level 3 with no warnings emitted.

	o VC++ build no longer attempts to fake "long long" support.  See
	  the Wishlist for further thoughts on this.


1.7.15, 2004.09.02 (r144)

	o Renamed Configure file to common.am, to avoid file name conflict
	  with configure script on case-sensitive file systems.

	o Added ebuild file and ebuild target to top-level Makefile for
	  Gentoo systems.  Thanks to Chris Frey for this.

	o Small efficiency improvements to BadQuery exception handling.
	  Initial idea by Chris Frey, improvements by Warren Young.


1.7.14, 2004.08.26 (r130)

	o Builds with Visual C++ 7.1.

	o Fixed a bug in custom macro generation that caused problems with
	  GCC 3.4.  (X_cus_value_list ctor definition was broken.)


1.7.13, 2004.08.23 (r92)

	o Removed USL CC support.  (System V stock system compiler.)  Use
	  GCC on these platforms instead.

	o Added examples/README, explaining how to use the examples, and
	  what they all do.

	o Most of the example programs now accept command line arguments for
	  host name, user name and password, like resetdb does.

	o Renamed sinisa_ex example to dbinfo.

	o Several Standard C++ syntax fixes to quash errors emitted by
	  GCC 3.4 and Borland C++ Builder 6.  Thanks to Steffen Schumacher
	  and Totte Karlsson for their testing and help with these.

	o Added proper #includes for BCBuilder, plus project files for same.
	  Thanks to Totte Karlsson for these.


1.7.12, 2004.08.19 (r63)

	o Many Standard C++ fixes, most from the GCC 3.4 patch by
	  Rune Kleveland.

	o Added Wishlist file to distribution.

	o Fixed a problem in the bootstrap script that caused complaints
	  from the autotools on some systems.

	o RPM building is working properly now.

	o Fixed the idempotency guard in datetime1.hh.


1.7.11, 2004.08.17 (r50)

	o Renamed mysql++, defs and define_short files, adding .hh to the
	  end of each.  (They're header files!)  This shouldn't impact
	  library users, since these are hopefully used internal to the
	  library only.

	o Removed sqlplus.hh file.  Use mysql++.hh instead.
	
	o Added mysql++.spec, extracted from contributed 1.7.9 source RPM, 
	  and updated it significantly.  Also, added an 'rpm' target to
	  Makefile.am to automate the process of building RPMs.

	o Added bootstrap and LGPL files to distribution tarball.

	o Added pre-1.7.10 history to this file.

	o Removed .version file.  Apparently it's something required by old
	  versions of libtool.


1.7.10, 2004.08.16 (r27)

	o Maintenance taken over by Warren Young (mysqlpp at etr dash usa
	  dot com.) See http://lists.mysql.com/plusplus/3326 for details.

	o Applied many of the GCC 3.x patches submitted for 1.7.9 over
	  the years.  This allows it to build on everything from 3.0 to
	  3.3.3, at least.  Because so many patches are rolled up in one
	  big jump, it's difficult to describe all the changes and where
	  they came from.  Mostly they're Standard C++ fixes, as GCC
	  has become more strict in the source code that it will accept.

	o MysqlRow used to overload operator[] for string types as well as
	  integers so you could look up a field by its name, rather than by
	  its index.  GCC 3.3 says this is illegal C++ due to ambiguities in
	  resolving which overload should be used in various situations.
	  operator[] is now overloaded only for one integer type, and a
	  new member function lookup_by_name() was added to maintain the old
	  by-field-name functionality.

	o Fixed another operator overloading problem in SSQLS macro
	  generation with GCC 3.3.

	o The _table member of SSQLS-defined structures is now const char*,
	  so you can assign to it from a const char* string.

	o Got autoconf/automake build system working with current versions
	  of those tools again.  Removed the generated autotools files from
	  CVS.

	o Renamed library file from libsqlplus to libmysqlpp.


1.7.9 (May 1 2001) Sinisa Milivojevic <sinisa@mysql.com>

    * Fixed a serious bug in Connection constructor when reading MySQL
    * options
    * Improved copy constructor and some other methods in Result /
    * ResUse
    * Many other minor improvements
    * Produced a complete manual with chapter 5 included
    * Updated documentation, including a Postscript format

1.7.8 (November 14 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * Introduced a new, standard way of dealing with C++ exceptions.
    * MySQL++ now supports two different methods of tracing exceptions.
    * One is by the fixed type (the old one) and one is standard C++
    * type by the usage of what() method. A choice of methods has to be
    * done in building a library. If configure script is run with
    * -enable-exception option , then new method will be used. If no
    * option is provided, or -disable-exception is used, old MySQL++
    * exceptions will be enforced. This innovation is a contribution of
    * Mr. Ben Johnson <ben@blarg.net>
    * MySQL++ now automatically reads at connection all standard MySQL
    * configuration files
    * Fixed a bug in sql_query::parse to enable it to parse more then 99
    * char's
    * Added an optional client flag in connect, which will enable usage
    * of this option, e.g. for getting matched and not just affected
    * rows. This change does not require any changes in existing
    * programs
    * Fixed some smaller bugs
    * Added better handling of NULL's. Programmers will get a NULL
    * string in result set and should use is_null() method in ColData to
    * check if value is NULL
    * Further improved configuration
    * Updated documentation, including a Postscript format

1.7.6 (September 22 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This release contains some C++ coherency improvements and scripts
    * enhacements
    * result_id() is made available to programmers to fetch
    * LAST_INSERT_ID() value
    * Connection constroctur ambiguity resolved, thanks to marc@mit.edu
    * Improved cnnfigure for better finding out MySQL libraries and
    * includes
    * Updated documentation, including a Postscript format

1.7.5 (July 30 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This release has mainl bug fixes  and code improvements
    * A bug in FieldNames::init has been fixed, enabling a bug free
    * usage of this class with in what ever a mixture of cases that is
    * required
    * Changed behaviour of ResUse, Result and Row classes, so that they
    * could be re-used as much as necessary, without any memory leaks,
    * nor with any re-initializations necessary
    * Fixed all potential leaks that could have been caused by usage of
    * delete instead of delete[] after memory has been allocated with
    * new[]
    * Deleted all unused classes and macros. This led to a reduction of
    * library size to one half of the original size. This has
    * furthermore brought improvements in compilation speed
    * Moved all string manipulation from system libraries to
    * libmysqlclient, thus enabling uniformity of code and usage of 64
    * bit integers on all platforms, including Windows, without
    * reverting to conditional compilation. This changes now requires
    * usage of mysql 3.23 client libraries, as mandatory
    * Changed examples to reflect above changes
    * Configuration scripts have been largely changed and further
    * changes shall appear in consecutive sub-releases. This changes
    * have been done and shall be done by our MySQL developer Thimble
    * Smith <tim@mysql.com>
    * Changed README, TODO and text version of manual. Other versions of
    * manual have not been updated
    * Fixed .version ``bug''. This is only partially fixed and version
    * remains 1.7.0 due to some problems in current versions of libtool.
    * This shall be finally fixed in a near future
    * Several smaller fixes and improvements
    * Added build.sh script to point to the correct procedure of
    * building of this library. Edit it to add configure options of your
    * choice

1.7 (May17 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This is mainly a release dealing with bug fixes, consistency
    * improvements and easier configure on some platforms
    * A bug in fetch_row() method of ResUse class has been fixed. Beside
    * changes that existed in a distributed patch, some additional error
    * checking has been introduced
    * A bug in escape manipulator has been fixed that could cause an
    * error if all characters had to be escaped
    * An inconsistency in column indexing has been fixed. Before this
    * version, column names in row indexing with strings, i.e.
    * row[<string>] , has been case sensitive, which was inconsistent
    * with MySQL server handling of column names
    * An inconsistency in conversion from strings to integers or floats
    * has been fixed. In prior version a space found in data would cause
    * a BadConversion exception. This has been fixed, but 100%
    * consistency with MySQL server has not been targeted, so that other
    * non-numeric characters in data will still cause BadConversion
    * exception or error. As this API is used in applications, users
    * should provide feedback if full compatibility with MySQL server is
    * desired, in which case BadConversion exception or error would be
    * abolished in some of future versions
    * A new method in ColData class has been introduced. is_null()
    * method returns a boolean to denote if a column in a row is NULL.
    * Finally, as of this release, testing for NULL values is possible.
    * Those are columns with empty strings for which is_null() returns
    * true.
    * Some SPARC Solaris installations had C++ exception problems with
    * g++ 2.95.2 This was a bug that was fixed in GNU gcc, as from
    * release 2.95 19990728. This version was thoroughly tested and is
    * fully functional on SPARC Solaris 2.6 with the above version of
    * gcc.
    * A 'virtual destructor ' warning for Result class has been fixed
    * Several new functions for STL strings have been added. Those
    * functions (see string_util.hh) add some of the functionality
    * missing in existing STL libraries
    * Conversion for 64 bit integers on FreeBSD systems has been added.
    * On those systems _FIX_FOR_BSD_ should be defined in CXXFLAGS prior
    * to configuring. Complete conversion to the usage of functions for
    * integer conversion found in mysqlclient library is planned for one
    * of the next releases
    * A completely new, fully dynamic, dramatic and fully mutable result
    * set has been designed and will be implemented in some of 2.x
    * releases
    * Several smaller fixes and improvements, including defaulting
    * exceptions to true, instead of false, as of this version
    * An up-to-date and complete Postscript version of documentation is
    * included in this distribution
    * Large chunks of this manual are changed, as well as README and
    * TODO files.

1.6 (Feb 3 2000) Sinisa Milivojevic <sinisa@mysql.com>

    * This is a major release as it includes new features and major
    * rewrites
    * Automatic quoting and escaping with streams. It works
    * automatically , depending on the column type. It will work with <<
    * on all ostream derived types. it is paricularly handy with query
    * objects and strstreams. Automatic quoting and escaping on cout,
    * cerr and clog stream objects is intentionally left out, as quoting
    * / escaping on those stream objects is not necessary. This feature
    * can be turned of by setting global boolean dont_quote_auto to
    * true.
    * Made some major changes in code, so that now execute method should
    * be used only with SSQL and template queries, while for all other
    * query execution of UPDATE's, INSERT's, DELETE's, new method exec()
    * should be used. It is also faster.
    * New method get_string is inroduced for easier handling / casting
    * ColData into C++ strings.
    * Major rewrite of entire code, which led to it's reduction and
    * speed improvement. This also led to removal of several source
    * files.
    * Handling of binary data is introduced. No application program
    * changes are required. One of new example programs demonstrates
    * handling of binary data
    * Three new example programs have been written and thoroughly
    * tested. Their intention is to solve some problems addressed by
    * MySQL users.
    * Thorough changes is Makefile system has been made
    * Better configuration scripts are written, thanks to D.Hawkins
    * <dhawkins@cdrgts.com>
    * Added several bug fixes
    * Changed Manual and Changelog

    * objects can be re-used
    * Changed sinisa_ex example to reflect and demonstrate this
    * stability
    * Changed Changelog and README
    * Few other bug fixes and small improvements and speed-ups

    * pointer_tracker
    * Corrected bug in example file fieldinf1
    * Finally fixed mysql_init in Connection constructor, which provided
    * much greater stability !

    * UnixWare 7.0 compiler

.64.1.1a (Sep 27 1998)

    * Fixed several bugs that caused my library to fail to compile with
    * egcs 1.1. Hopefully it will still compile with egcs 1.0 however I
    * have not been able to test it with egcs 1.0.
    * Removed some problem causing debug output in sql++pretty.

.64.1a (Aug 1 1998)

    * Added an (almost) full guide to using Template Queries.
    * Fixed it so the SQLQuery will throw an exception when all the
    * template parameters are not provided.
    * Proofread and speedchecked the manual (it really needed it).
    * Other minor document fixes.

.64.0.1a (July 31 1998)

    * Reworked the Class Reference section a bit.
    * Minor document fixes
    * Added more examples for SSQLS.
    * Changed the syntax of equal_list for SSQLS from equal_list (cchar

    * Added set methods to SSQLS. These new methods do the same thing as
    * there corresponding constructors.
    * Added methods for creating a mysql_type_info from a C++ type_info.

.64.a (July 24 1998)

    * Changed the names of all the classes so they no longer have to
    * have Mysql in the begging of it. However if this creates a problem
    * you can define a macro to only use the old names instead.
    * The Specialized SQL Structures (formally known as Custom Mysql
    * Structures) changed from mysql_ to sql_.
    * Added the option of using exceptions thoughout the API.
    * ColData (formally known as MysqlStrings) will now throw an
    * exception if there is a problem in the conversion.
    * Added a null adapter.
    * Added Mutable Result Sets
    * Added a very basic runtime type identification for SQL types
    * Changed the document format from POD to LYX .
    * Am now using a modified version of Perceps to extract the class
    * information directly from the code to make my life easier.
    * Added an option of defining a macro to avoid using the automatic
    * conversion with binary operators.
    * Other small fixed I probully forgot to mentune.

.63.1.a

    * Added Custom Mysql Structures.
    * Fixed the Copy constructor of class Mysql
    * Started adding code so that class Mysql lets it children now when

    * Added Template Queries
    * Created s separate SQLQuery object that is independent of an SQL
    * connection.
    * You no longer have to import the data for the test program as the
    * program creates the database and tables it needs.
    * Many small bug fixes.

.61.1.a (April 28 1998)

    * Cleaned up the example code in test.cc and included it in the
    * manual.
    * Added an interface layout plan to the manual.
    * Added a reverse iterator.
    * Fixed a bug with row.hh (It wasn't being included because of a
    * typo).

.61.0.a

    * Major interface changes. I warned you that the interface may
    * change while it is in pre-alpha state and I wasn't kidding.
    * Created a new and Separate Query Object. You can no longer execute
    * queries from the Mysql object instead you have to create a query
    * object with Mysql::query() and use it to execute queries.
    * Added the comparison operators to MysqlDate, MysqlTime and
    * MysqlDateTime. Fixed a few bugs in the MysqlDate... that effected
    * the stream output and the conversion of them to strings.
    * Reflected the MysqlDate... changes in the manual.
    * Added a new MysqlSet object and a bunch of functions for working
    * with mysql set strings.

    * Chris H)
    * Fixed bug in comparison functions so that they would compare in he
    * right direction.
    * Added some items to the to do list be sure to have a look.
