| 10:20 | Cherrypicked contents of checkin [8ef9b5fae0] accidentally made against trunk to the tip of branch smallc-85. This restores extern.h. Superseded by branch smc85-cc8. Closed-Leaf check-in: b2c0174786 user: poetnerd tags: smallc-85 | |
| 10:11 | Healed double-tipped smallc-85 branch: the first had no useful content, so the branch containing all the actual work basically merges into the stub. check-in: 6d2b6dec56 user: tangent tags: smallc-85 | |

| 05:37 | Snapshot: Fix for globals: We needed to quit allocating storage for functions. Debugging fetch of globals. They seem swapped with locals somehow. check-in: 50ae87a7e9 user: poetnerd tags: smallc-85 | |

| 05:15 | Looks like it's working! Deltas: GBLS and GLOBAL POOL output values are different, and I think that's because they used to be wrong. TODO: get n8.c and p8.c to compile on the Pi without errors for testing purposes! check-in: bd0ffae19c user: poetnerd tags: smallc-85 | |
| 01:43 | Take the version of cross/os8 I should have started with. Fix the problem with multiplying pointers by two when INTSIZE actually is 1. check-in: 220c52acab user: poetnerd tags: smallc-85 | |

| 16:55 | Snapshot: More stuff is working. TODO: get the numeric values to work correctly. Further fix to global symbol table output. Add the license file now canon upstream in SmallC-85. LATER: Merge the updates from trunk that predate the cc8-64-bit branch. (I should havve ported trunk, not the branch, but oh well...) check-in: a27c7fa2a1 user: poetnerd tags: smallc-85 | |
| 06:18 | Snapshot of refresh of cc8 cross compiler with smallc-85. This saves a copy of my work which merges enough of the old pdp8 targeting and the new cc8 platform to get through a build of src/cc8/os8/libc.c. The output code isn't quite correct yet, but it gets all the way through with mostly cosmetic errors, instead of crashing with illegal access or seg fault. check-in: 058d944b24 user: poetnerd tags: smallc-85 | |

| 18:20 | Updated the references to "mkos8" in doc/class-simh.md. There are still two references there for historical reasons, but the bulk of the text now refers to os8-run instead. check-in: bcf566411e user: tangent tags: trunk | |
| 18:07 | Rethought the policy on overwriting binary media: although it made sense to allow the new RK05 disk file names to merge with the old, this step also overwrites the boot scripts when that happens, and those may have user changes as well. Therefore, the new policy is that if *any* IF=0 default disk image is found, past or present, we skip mediainstall. You have to choose to run it by hand in that case, or follow the manual merge steps from README.md. check-in: 685d583d5a user: tangent tags: trunk | |
| 17:53 | Changed a bunch of "os8v3d*.rk05" references to their equivalent and current names. check-in: c2fc076dcc user: tangent tags: trunk | |
| 17:51 | Changed "make install" so that it skips "make mediainstall" based on the existence of v3d.rk05 rather than local.tu56 so that we merge our new media with v20171222, as that release was able to merge its os8v3d-* with the os8.rk05 of prior releases. This does mean the prior release's local.tu56 and pristine source tapes can get overwritten, but those weren't supposed to be changed by the user anyway. We don't wan't people doing "make install" and not understanding why their "new" system behaves just like the old one. check-in: 384bf04b34 user: tangent tags: trunk | |
| 16:22 | Changing boot scripts via IF + SING_STEP now detaches all devices, shuts down the GPIO thread, and re-launches the simulator with the new script rather than just call "do SCRIPTNAME" in order to get a fresh simulator configuration, free of conflicts. The case that prompted the need for this is switching between boot scripts that assume the tape controller is TC08 to one that assumes TD8E, or vice versa. The only other way we could solve this is to write "detach" commands at the top of every boot script to undo everything done by every other possible boot script. Closes [81d528e3]. check-in: 82cc1aebca user: tangent tags: trunk | |
| 16:00 | The installation tree is now entirely owned by @INSTUSR@.@INSTGRP@. We still had a mix of root.root in there, due to the way the tree was being created, resulting in oddities like the normal user could write to the installed OS/8 media but couldn't remove them from disk. check-in: b08f63333c user: tangent tags: trunk | |
| 15:45 | Adjusted the ChangeLog.md entry on boot tapes to reflect the fact that all four are always built: you aren't selecting one to build, you're choosing which one gets used for IF=3. check-in: c7d1f02b34 user: tangent tags: trunk | |
| 15:35 | Cosmetic tweak for recent Makefile.in change check-in: 675d87a243 user: tangent tags: trunk | |
| 13:46 | test-os8-run uses a custom bin/* set, so it was still hard-coded to get bin/pidp8i-bin, not bin/pdp8 as class simh now expects when we pass True for the skip_gpio ctor flag. check-in: 8193ea0be2 user: tangent tags: trunk | |
| 13:40 | The test-os8-run Makefile target now runs the program first in -g mode then in -e mode only if that returns without error. When you say "make test-os8-run", you almost certainly don't want to begin re-testing all of the existing exemplars without having a complete test corpus first. If you want to test on an incomplete corpus, you can run in -e mode manually. check-in: 0cf1c0e9bb user: tangent tags: trunk | |
| 12:39 | When a program passes True for the formerly-named "ignore GPIO lock failure" flag to class simh, it now runs bin/pdp8 instead of bin/pidp8i-sim which disables the GPIO thread per [daa86ad9b6]. Consequently, the simh ctor no longer checks for the "Failed to lock GPIO" error from the simulator, and it checks for the SIMH startup banner intead of the PiDP-8/I GPIO thread startup banner, which may now never appear. Finally, this checkin modifies the interface of simh.try_wait to be more of a simple wrapper around simh._child.expect with exception handling built in; this is deemed safe, since class simh is the only known user of this public API. This fixes bug [b876ef8c]. check-in: d7b5cbd7cb user: tangent tags: trunk | |
| 11:37 | Removed the target added on the os8-v3f-extensions branch for media/os8/3finit.tx, which is built from a *.in file, because we'd previously choked this down to a single file, media/os8/init.tx in order to force a parallel build to go single-threaded at this point, since the configure script can't be sanely run more than once in parallel. The clue we needed to fix this is that on touching any *.in file and doing an mmake is that you'd get the "Fossil doesn't work here" complaint from auto.def because it's trying to lock the repo DB twice in parallel; one fails, the other succeeds, so it looks like there is no problem and the complaint is apropos of nothing. It's actually flagging a real problem! check-in: 19b31029e5 user: tangent tags: trunk | |
| 11:32 | The pidp8i-sim Makefile target also creates a hard link to bin/pdp8 now, so we can use it from class simh, especially via os8-run. check-in: a3afe42e70 user: tangent tags: trunk | |
| 11:09 | If the simulator is not called as "pidp8i-sim", we now disable the GPIO thread: it doesn't get started, we don't feed it with data, and we don't pull any data it is expected to provide. Additionally, the Makefile now creates a @prefix@/bin/pdp8 hard link to make the simulator fall back to a state nearly identical to the upstream SIMH version by triggering this new feature. This is in partial support of ticket [b876ef8c25]. check-in: daa86ad9b6 user: tangent tags: trunk | |
| 10:27 | Small cosmetic fixes in Makefile.in check-in: 94d64e2c34 user: tangent tags: trunk | |
| 09:58 | Found and fixed the cause of the obj/os8-run.log overwrite during test-os8-run, avoiding the need for the concatenation dance previously done to avoid the problem. check-in: 22dc5521d8 user: tangent tags: trunk | |

| 20:10 | Increased class simh's on-startup timeout from 3 to 5 seconds to try and avoid pexpect timeout errors when the system is busy, as can happen when the cores are oversubscribed doing test-os8-run passes and then a background process starts. (And on top of that, there's probably an I/O stall in there somewhere, like an SSD TRIM or cache flush.) check-in: 41b3353407 user: tangent tags: trunk | |

| 23:51 | Merge os8-v3f-extensions branch to trunk. This replaces the old mkos8 builder with a generic scripting facility, os8-run. It also puts some historical sources "os8-v3f" under source control to build an update from OS/8 v3d. The ultimate aim of the v3f work is to re-generate the lost OS/8 Combined Kit which includes device drivers from the "OS/8 Device Extensions Kit" as well as integration of pieces that were formerly add-ons. The "Combined Kit" work is now possible. check-in: b7bc669fdc user: poetnerd tags: trunk | |
| 04:46 | Added a timeout parameter to simh.os8_send_cmd() with a default that lets the current os8-run scripts run without timing out when running especially long commands such as the CCL.BI assembly step on an old Raspberry Pi model B+. (We'd been declaring success while running on much faster platforms, which have correspondingly shorter maximum run times for these commands.)

| 22:32 | Passing debug flag from os8-run down into class simh. check-in: 66cca79b3c user: tangent tags: os8-v3f-extensions | |
| 18:18 | Avoiding the ^C was mis-nested, and only active when debugging was enabled. Fixed now. check-in: 7577fa194d user: poetnerd tags: os8-v3f-extensions | |
| 16:17 | Check in the CORRECT change to conditionalize on debug. check-in: 58762d8480 user: poetnerd tags: os8-v3f-extensions | |
| 16:17 | Fix debug noise. It was not properly conditional on self.debug. check-in: cacac3bb8a user: poetnerd tags: os8-v3f-extensions | |
| 10:26 | It is now possible to give a hash prefix of as few as 6 characters when identifying a particular test by hash to test-os8-run. check-in: 0cea4c1f35 user: tangent tags: os8-v3f-extensions | |
| 10:16 | Added inc::Module::Install to cpanfile: my Pi B needed it. check-in: 46248e133a user: tangent tags: os8-v3f-extensions | |
| 09:52 | It is now possible to pass hashes of prior generated tests to test-os8-run to re-test just those named tests. This is an alternative to -e when you want to re-test just some subset of the tests without looking the test up manually and re-running the test by hand. check-in: a1f53d7064 user: tangent tags: os8-v3f-extensions | |
| 09:25 | Extracted generate_tests() in test-os8-run. check-in: 684f72e682 user: tangent tags: os8-v3f-extensions | |
| 09:12 | Further cleanup of main() in test-os8-run. check-in: 17b868fbe2 user: tangent tags: os8-v3f-extensions | |
| 09:09 | Added --version and --help handling to tools/test-os8-run. check-in: 06d8af86f4 user: tangent tags: os8-v3f-extensions | |
| 06:26 | Refinements to sanitizing: 1. Cleans up -temp-<gensym>.foo temporaries for scratch media. 2. Cleans up -<pid>.pt_temp paper tape temporaries. 3. Cleans out backspace sequences that pexpect seems gratuitiously to enter which screw up the other sanitizers. These are nasty regexps. Special thanks to regex101.com without which these nasty regexps could not have been prototyped. check-in: e34afedcba user: poetnerd tags: os8-v3f-extensions | |
| 03:57 | Additional debugging of race condition in running BUILD in v3d-dist-rk05.os8: 1. Slight cleanup of debugging messages in os8script.py:build_subcomm. 2. Teach test-os8-run to preserve make.log as {last,fail}m.log. 3. Add logic in os8script.py:build_subcomm to NOT send ^C after successful BOOT command, because we are already at command level, and it creates a race condition in the expect command loop. TODO: 1. Sanitize log output to ignore temp file names for scratch images. 2. Cleaner handling of make.log saves. check-in: b7fdc79a38 user: poetnerd tags: os8-v3f-extensions | |

| 22:15 | Take steps to preserve the os8-run.log file from the first time through os8-run making v3d-dist.rk05. For reasons I do not understand, the two runs of os8-run create new log files rather than appending the second run to the first file. check-in: 60386aa52a user: poetnerd tags: os8-v3f-extensions | |
| 21:08 | Draft of tool to unpack os8 packs that test-os8-run says are different. Attempt to fix v3d-dist-rk05.os8 script to allow test-os8-run to sanitize the init.txt. check-in: 268d30c309 user: poetnerd tags: os8-v3f-extensions | |

| ||
| 03:42 | The less intrusive "os8_resume" has proven unreliable with 8 parallel makes going on for test-os8-run. The symptom is that we go to resume OS/8, but instead of provoking a dot prompt from OS/8, we seem to send ^C to SIMH before it ever resumes OS/8 operation. So now we call the restart_command instead of the resume_command inside os8script.py. This seems to operate reliably. check-in: 98ad1fc68b user: poetnerd tags: os8-v3f-extensions | |
|
2018-11-24
| ||
| 21:18 | Added "--prefix ." to call to ../../../configure in test-os8-run. This should eliminate a whole class of race conditions, because now it will build the run packs in tmp/<pid> subdirs instead of the usual top level. check-in: 865bf2ccdc user: poetnerd tags: os8-v3f-extensions | |

| 04:23 | Addresses bugID 9c8f0a8de5 Puts conditional around SET SYS INIT in the v3d-dist-rk05.os8 script. Need to come to consensus on whether or not this is the right fix, and if the same change should be made to all-tu56.os8 before we can officially close that bug. check-in: b9956a79f0 user: poetnerd tags: os8-v3f-extensions | |

| 04:52 | The autosetup check for lz4 in the path was failing either way: when the tool is available, it was running it in a way that caused it to return a nonzero status code, failing the check. check-in: 70d23bbd7d user: tangent tags: os8-v3f-extensions | |
| 04:47 | Renamed test-mkos8 to test-os8-run, since mkos8 is now replaced with os8-run. Also renamed all of the references to it. check-in: 0211633f80 user: tangent tags: os8-v3f-extensions | |
| 04:39 | The top-level Makefile now disables the test-mkos8 target when tools/test-mkos8 can't run due to missing prereqs. check-in: 79a16d5ab5 user: tangent tags: os8-v3f-extensions | |

| 15:55 | Added lz4 prereq to the test-mkos8 autosetup tests check-in: c46ae7cc93 user: tangent tags: os8-v3f-extensions | |

| 08:59 | test-mkos8 is now working with os8-run to successfully create the v3d.rk05 image for comparison checking. Open Questions: 1. Is further refinement needed for the log sanitizizing? 2: Is comparing the binary of the disk image the best test? check-in: 5e4633e246 user: poetnerd tags: os8-v3f-extensions | |
| 02:06 | Found the problem with running ../../configure in test-mkos8: Needed to add back the line to auto.defs that creates the lib subdir that hosts the options file: if {![file exists "lib/pidp8i"]} { file mkdir "lib/pidp8i" } check-in: 408edf8633 user: poetnerd tags: os8-v3f-extensions | |
| 00:21 | Snapshot: Trying to get test-mkos8 working. ../../../configure from the test/tmp/<pid> directory blows out with: Error: couldn't open "lib/pidp8i/os8opts.py": no such file or directory check-in: d2986ecfba user: poetnerd tags: os8-v3f-extensions | |

| 19:24 | I misunderstood how to do mediainstall, and what I had was not installing all of what we made. Fixed now. check-in: d6f48ac376 user: poetnerd tags: os8-v3f-extensions | |
| 01:00 | Fixes to uniquify resources that might be used in parallel make. Also cosmetics: changed "scratch" name to have "-temp-" in it to make it easier to find and delete if make blows out. Since I was touching the use of the system disk in all-tu56.os8, I cleaned out some dead code and updated as comment. check-in: b2a6c5d89e user: poetnerd tags: os8-v3f-extensions | |

| 03:22 | all-tu56.os8 was copying in DTCOPY.SV and DTFRMT.SV insgtead of TDCOPY.SV and TDFRMT.SV when building for td8e. check-in: 32377aac5c user: poetnerd tags: os8-v3f-extensions | |
| 03:19 | scratch option os8-run mount command now creates a unique temp file. Now parallel makes will not step on each other. check-in: 2f3f1ca884 user: poetnerd tags: os8-v3f-extensions | |
| 01:25 | Fixed bug in all-tu56.os8: The old code to clean up the system rk05 that was commented out was lacking an "end enabled never", and so it caused the rest of the file to be ignored. This messed up all td12k creations. check-in: 8e309b3872 user: poetnerd tags: os8-v3f-extensions | |
| 01:23 | Added more debugging output. Line count stack was wrongly managed because Python pop semantics are the opposite of what I thought. So I was removing the first in, not the last in item from there. check-in: 85804b2ac3 user: poetnerd tags: os8-v3f-extensions | |

| 03:30 | Moved v3f-build.rk05 to the obj directory. Along the way taught os8-cp to do path expansion on names in dirs.py just like os8-run does. This enabled a simplificaiton and cleanup of Makefile.in because the actions file in .../src/os8/v3f/actions.txt simply says that the destination lives in $obj. Also needed to update dirs.py.in to know about obj, as it knows about bin. check-in: bb42538cf0 user: poetnerd tags: os8-v3f-extensions | |

| 00:40 | Merged in v3f-parallel-make-fix. It behaves the same for me as previous versions, but no sense in forking. check-in: f3b2941356 user: poetnerd tags: os8-v3f-extensions | |

2018-10-28
| ||
| 08:24 | Added (and in one case, reordered) some dependencies in the new os8-run based media build system so that all callers to os8-run from the Makefile now declare which media they require to exist before the script will run. Without this change, parallel makes are likely to fail because make is given the freedom to run targets before the things they're dependent upon exist. This is a branch rather than on the os8-v3f-extensions branch directly because I can't test it here against the tip of that branch due to a missing file. Also, it should be checked by Bill Cattey before being merged into that branch. Closed-Leaf check-in: 5a84eb18d9 user: tangent tags: v3f-parallel-make-fix | |

| 20:32 | Here's why it's always good to do the occasional fossil clean -n: I see I FORGOT to add the LCSYS.BI and UCSYS.BI files to the tree. Can't do the builds I've got running without them. check-in: 30b1f33839 user: poetnerd tags: os8-v3f-extensions | |
| 20:21 | Enables all the lowercase option for v3d and v3f tapes and in the 3.script and run-v3f.script scripts. TODO: Enable lowercase for BASIC in v3f. That script isn't qualified, and there's a backlog of patches and validation on BASIC that are needed. check-in: db857bdac1 user: poetnerd tags: os8-v3f-extensions | |

| 18:54 | Additional debugging output, and a correction to the build_subcomm state machine during the BUILD command run within BUILD.SV. There was some duplicate code, and I think I may have spazzed and never properly exited the BUILD command state machine. check-in: 497f79dad6 user: poetnerd tags: os8-v3f-extensions | |
| 18:00 | Add missing dependency on the v3d.rk05 boot image to the making of v3f. check-in: b17e1072b9 user: poetnerd tags: os8-v3f-extensions | |
| 17:47 | Further refinement of make run-v3f: Sets dependency independently of what was specified as the default IF=3 OS/8 version. check-in: 464fcf21de user: poetnerd tags: os8-v3f-extensions | |
| 03:49 | The new run-v3f target was depending on one of the two possible TU56 tape images that could be in boot/3.script after configure runs, meaning the dependencies were correct for only one of the two possible cases. This target is now dependent on the same autosetup variable used to create 3.script from 3.script.in, so we're sure to build the correct tape image before starting the simulator. check-in: 8b39a5cb89 user: tangent tags: os8-v3f-extensions | |
| 03:01 | Correct dependency: We need to depend on $(OS8_BOOT_DISK) because that is what we will be running, not the renamed bin disk that had no patches. check-in: b247b928cf user: poetnerd tags: os8-v3f-extensions | |

| 06:06 | Something I should have done long ago: If we're going to re-configure sys, then we should use a scratch copy. all-tu56.os8 now does that for the td12k builds. It doesn't need to do that for the tc08 builds so it doesn't bother. Also changed the filename of the scratch to use "-copy" in the name instead of "_copy" aligning with filename conventions. check-in: f67db97d71 user: poetnerd tags: os8-v3f-extensions | |
| 05:40 | Fixed some noise. simh.py was printing stuff by default. Added a verbose internal variable to the simh object and updated os8-run and os8-cp.in to set that variable to True when they get the verbose option. check-in: fe46cf1a76 user: poetnerd tags: os8-v3f-extensions | |
| 05:23 | FIXED problem where make kept re-making v3d-src.rk05: Misuse of os8-run mount command's option "preserve". The NEW version got a new name with a version number and the old version was kept. Make kept finding the original version. The CORRECT option to use is "new" not "preserve". check-in: 48bf62dd63 user: poetnerd tags: os8-v3f-extensions | |
| 04:41 | all-tu56.os8 now copies in appropriate DECtape utilities: TD8E configs get: TDCOPY.SV, TDFRMT.SV TC08 configs get: DTCOPY.SV, DTFRMT.SV check-in: 4ee3a65c2a user: poetnerd tags: os8-v3f-extensions | |
| 04:30 | Enabled builds of all 4 tu56 images: v3d-tc08.tu56, v3d-td12k.tu56, v3f-tc08.tu56, v3f-td12k.tu56. Amended all-tu56.os8 and v3d-dist-rk05.os8 to put the following td8e drivers into the SYS:BUILD.SV image: TD8ESY.BN (12k system handler), ROMMSY.BN (rom system handler), TD8EA.BN. Left out were the B, C, and D TD8E non-system handlers. (I was paranoid about space.) Extensive comments in the scripts throughout on the various tradeoffs and dependencies. check-in: 0e4030caec user: poetnerd tags: os8-v3f-extensions | |
| 04:13 | That's what I get for assuming instead of testing. :-( This one PROPERLY specifies the copyin for ABSLDR.SV and is tested. check-in: 16dc21707a user: poetnerd tags: os8-v3f-extensions | |

| 05:46 | Snapshot: Mostly working "all-tu56.os8" script that builds v3d or v3f on tc08 or td12k or tdrom system. TODO: More testing. Make the V3D rk05 BUILD.SV already contain the TD8E drivers. Decide on an INIT file. check-in: 857984d41b user: poetnerd tags: os8-v3f-extensions | |
| 04:33 | Bug fixes to basic_line_parse. I'm using a LOT of conditionals now, and apparently there were several bugs that I missed: 1. basic_line parse was not using the stripped version of line. 2. The options stack pop was taking the the wrong member of the stack so it was a first in last out, instead of the intended first in first out stack. 3. The test for comments was on the pre-stripped line so that comments could not be indented with whitespace. check-in: bfccd73f14 user: poetnerd tags: os8-v3f-extensions | |

| 23:15 | Added version and directory expansions into the print command. Includes print-test.os8 to test them. check-in: f14e1e8973 user: poetnerd tags: os8-v3f-extensions | |
| 20:33 | The \s test for whitespace in tools/corecount wasn't working on NetBSD 6 for some reason, so changed it to the POSIX [[:space:]] character class. This should be effective on many more systems. check-in: b5e424045e user: tangent tags: trunk | |
| 03:35 | Got the build of os8-v3f for TD8E DECtape working again. Root cause: I still don't understand the BUILD command loop well enough, and I wrote it! I added a couple more special cases so now everything, including the TD8E build works. Clearer code will come when the pexpect loop is turned right way round. Couple things: Building the v3f tu56 images for BOTH TC08 and TD8E are now enabled by default. WARNING: If the TD8E build blows out it leaves the v3d.rk05 system pack with td8e devices enabled instead of tc08. The new script, v3d-reset-tc08.os8 fixes this. QUESTION: Do we make this situation more bullet proof by: Creating a copy of v3d.rk05 when we build for TD8E? or Building Unconditional cleanup code into os8-run for on-error, do such and such to clean up? Actually, I could probably modify the v3d-dist-rk05.os8 script to put both the TD8EA and TC08 drivers in the image of BUILD.SV, if there is room. Maybe I'll just do that. check-in: b24aa7b9d7 user: poetnerd tags: os8-v3f-extensions | |
| 01:30 | Add dependency on patches. Note that this depends on ALL .patch8 file regardless of whether or not we actually use them. A finer grained dependency could be done in the future. check-in: b9ceacad42 user: poetnerd tags: os8-v3f-extensions | |
| 01:28 | Add two more files to make clean action: lib/pidp8i/dirs.py lib/pidp8i/ips.py check-in: 8a974ca3b9 user: poetnerd tags: os8-v3f-extensions | |
| 01:24 | Further cleanup of Makefile.in: Further purging of "mkos8" methods and concepts: 1. MKOS8_OPTS->OS8_OPTS 2. Where mkos8 became os8-run rename files, directories, scripts and dependencies appropriately. 3. Eliminate 'mkos8' install dir and ctags. 4. Scripts named MKOS8_* now have names more related to their current function under os8-run, and may have been further changed to reflect our v3d/v3f naming and simplification. 5. make clean eliminated the mkos8 directory. 6. make targets for use by test-mkos8 updated with new names, but really needs to be redone now that patching is unconditional. check-in: d6f23aaeda user: poetnerd tags: os8-v3f-extensions | |

| 21:06 | Make patching unconditional. Amend apperopriate documents to no longer talk about a --disable-os8-patches option. Make the text file that names the patches conform to current filename conventions. check-in: a2454ca487 user: poetnerd tags: os8-v3f-extensions | |
| 20:41 | Adopted new filename conventions: .mkos8 -> .os8 underscores to dashes test scripts end in -test instead of beginning with it Shortened names. Fixed up dependencies, including broken one on newly renamed v3f-*.tu56. check-in: 55e34d0b34 user: poetnerd tags: os8-v3f-extensions | |
| 18:02 | I had not done rigorous enough testing. Here is better test case, corrected code, and elimination of the old fancier test code. check-in: aa9df2a6e8 user: poetnerd tags: os8-v3f-extensions | |
| 17:33 | Simplified version test. Warren justified "just test for version X or above" by showing allowing richer matches just made it easy for people to leaving incompatibilities in place. Changed name of the tester script to replace underscore with dash, say "version" first, and most importantly to adopt a new convertion: ".mkos8" scripts become ".os8". check-in: 1fcde938d6 user: poetnerd tags: os8-v3f-extensions | |

| 01:32 | checkin cd80254374 was incomplete: auto.def created lib/mkos8 to host generated python files that are now kept in lib/pidp8, so we delete that line. Makefile.in still had the old MKOS8 python file list so 'make install' was doing the wrong thing.

| 03:34 | Remove the bespoke --enable-<foo> and --disable-<foo> arguments. Use the generic --enable and --disable arguments. Note that the usage message still informs about all known enable/disable args created in lib/mkos8/opts.py by auto.defs. However the usage message is clearer now and the arg parsing is simpler now. Note we delete the use of the fancy python argparse library. Nice as it was, we don't need it. The clearer usage message is also in the os8-run.md doc. check-in: 0f1c58479b user: poetnerd tags: os8-v3f-extensions | |

| 03:12 | Bug fix: If we build with config option --os8-minimal, we won't build the os8v3d-patched.rk05 image. We only build os8-v3f from that image. --os8-minimal therefore should not attempt to build os8-v3f. check-in: e14bed0e60 user: poetnerd tags: os8-v3f-extensions | |
| 02:59 | Bug-fix: When we use config option --os8-minimal the system image os8v3d-patched.rk05 does not exist. Creating the source packs does not require a patched system anyway, so we use os8v3d-bin.rk05. check-in: afabf0c0e7 user: poetnerd tags: os8-v3f-extensions | |

The more correct term for how we build is "from distribution media" rather than "source media" because we don't build from source, and because "distribution media" is the correct term used for our baseline truth. 2. Cleaned up broken formatting in the pal8 section's bulleted list, and in the begin/end keyword table. 3.

| 02:49 | Snapshot: Minimum Makefile.in changes needed to replace execution of mkos8 with execution of os8-run. TODO: 1. Put in the dependencies on the new python modules. 2. rip out mkos8. 3. Confirm this all works for someone else. 4. CLEANUPS. check-in: c610c24d5d user: poetnerd tags: os8-v3f-extensions | |
| 01:47 | The done command was a mistake and now is gone. I realized it was a mistake when, we executed it in an included script, the scratch files were removed. Rather than creating a per-script scratch list, I moved the final cleanup to the main os8-run code and deleted the done command. check-in: 8b66b4f06b user: poetnerd tags: os8-v3f-extensions | |
| 00:36 | In cutting over to using os8-run I realized I needed a mount option that lets the script create a new empty image file and saves a pre-existing version. The "new" option to mount is now implemented. check-in: 26c846c5ce user: poetnerd tags: os8-v3f-extensions | |

| 02:31 | Teach call_pal8 to detect failure of PAL-8 to start. TODO: Re-do ALL the calls to os8_send_cmd to shift from looking for a command prompt before beginning a command and then maybe testing the command result (which is currently implemented with os8_send_cmd (prompt_string, command) ) to: Running a command and then testing the result. Yes, this means that pretty much the entirety of the command execution and result testing has been implemented in the wrong order. check-in: 6ce374d437 user: poetnerd tags: os8-v3f-extensions | |

2018-05-18
| ||
| 05:01 | Added path expansion to copy_into and copy_from. Fixed two related bugs: 1. path expand needed to use os.path.join to deal with how dirs.py ends some dirs with a slash, and some not. 2. copy_into and copy_from needed to check to see if the system was booted. (I'd forgotten this requirement, didn't boot the dectape, and could not understand why things were failing.)

| 13:28 | Simplified [05371feb7c], replacing the redundant map of module variable names to their values with a call to getattr() on the module and variable name in the single place that used this new facility. check-in: 2475d3ad2c user: tangent tags: os8-v3f-extensions | |
| 05:00 | Added directory expansion for Anchor directores found in dirs.py.in. This necessitated offering them up in an associative array, as well as directly in dirs.<varname>. TODO: Document this.

| 18:41 | Apparently when I got os8v3d-bin.mkos8 working, I broke the tco8.mkos8 script. That script is for creating an os8-v3f dectape, so I renamed it and got it working again. TODO: Get os8v3d-bin.mkos8 validated. When I added resume, I turned off the simh command.

| 06:59 | Snapshot: Added line number management so that all errors give the line number of the script file. (We keep a stack of line numbers corresponding to the nesting of included files.) Almost done, but it's hours past bed time! check-in: 9b8e035e77 user: poetnerd tags: os8-v3f-extensions | |
| 05:44 | Previous commit was an error. I thought I'd completed the commit and then I addeed a bunch of code on an unrelated issue. THIS commit adds the boot checking AND NOTHING ELSE. check-in: 4c351aa5b2 user: poetnerd tags: os8-v3f-extensions | |
| 05:28 | boot command checks to see if the device to be booted has something attached. If not, the script dies. Commands that run in an OS/8 context check the state of "booted" and if we have not been booted, the script dies. check-in: e9baca9803 user: poetnerd tags: os8-v3f-extensions | |
| 01:59 | Added return status of "success", "fail", or "die" to all script commands. fail doesn't do much now. This is really about the die status. Also return values from routines called in simh.py are inconsistently set (rarely at all). And the return values are currently never tested. check-in: ccf3cc63e3 user: poetnerd tags: os8-v3f-extensions | |
| 01:41 | Use :os8_send_ctrl to send ^C. Slightly cleaner. check-in: 5d248e2f70 user: poetnerd tags: os8-v3f-extensions | |

| 23:41 | I thought I tested this way of implementing resume, but apparently not. This fixes the new resume to work the way the previous check-in should have worked. check-in: 24125be341 user: poetnerd tags: os8-v3f-extensions | |
| 22:51 | Further exploration of what it means to resume OS/8. Comments in simh.py explain the problem: We need to provoke a prompt to re-synchronize with python expect after resuming the stuff that was running under SIMH. There is now a resume command that does the minimum, but it's not as minimal as I would like: It sends ^C, which forces a return to the keyboard monitor if you happen to use it in the following situation: Start an OS/8 program. Escape to SIMH Resume. The ^C will kill the OS/8 program and send you back to the keyboard monitor. This is less disruptive than go 7600, but still not ideal. Just sending newline, or multiple newlines, or erase character or kill line to the OS/8 keyboard monitor after issuing the continue command in SIMH does not work to give you a command prompt. The next revision, I think will touch many routines to do the following: Create a sense of when to abort the whole script. Allow the script runner to keep track of OS/8 context and either blow out when you try to issue an OS/8 command before having booted an image, or to resume OS/8 for you when you use simh commands. check-in: b1e7201347 user: poetnerd tags: os8-v3f-extensions | |

| 22:33 | Refine two different options parsing strategies: In current strategy, be clearer on the effect of --enable and --disable args. In an alternate strategy, --enable-foo and --disable-foo become two word arguments. This can be done without changing the actions of auto.def, but DOES require changes to how configure would parse command line arguments. check-in: 1dc45457c5 user: poetnerd tags: os8-v3f-extensions | |
| 22:32 | Several minor improvements to HACKERS.md check-in: 3c19d18b26 user: tangent tags: trunk | |
| 03:58 | Fixed argument parsing in mkos8 that I broke when I was experimenting with and evolving the ideas of how to pass in new options. Now instead of -o --option, mkos8 responds to --enable and --disable To set open ended enablement and disablement options that are not defined elsewhere. check-in: 025010d6f3 user: poetnerd tags: os8-v3f-extensions | |
| 00:01 | os8-run now does patching and with os8v3d-patch.mkos8 reproduces full functionality of mkos8 patch. Additional command, "copy" added to take the os8v3d-bin.rk05 image and copy it into a new file os8-v3d-patched.rk05. The latter file is then mounted and patched, just like mkos8 does it. check-in: 3f562abc9c user: poetnerd tags: os8-v3f-extensions | |

| 04:35 | New option to mount, "copy_scratch" that creates a writeable scratch copy of what is to be mounted, which gets deleted when done.

| 03:55 | The script runner now has the "Set INIT message" functionality: 1. We don't create INIT.CM with the editor. Instead we copy it in just as we do with INIT.TX. 2. os8script.py now has script interfaces to the simh.py routines: copy_into -> os8_pip_into copy_from -> os8_pip_from 3. os8v3d-bin.mkos8 is updated. Booting the resulting rk05 image DOES run the INIT.CM script properly. TODO: 1. Figure out an interface in the script runner for the functionality of: "create a bootable dectape copy from the read-only distribution tape." 2.

| 03:08 | Bug fix: We never before tested calling os8_pip_from and os8_pip_into with a null option argument. The code didn't actually work because we were treating option later as a string.

Going on the principle of charity here, I assume that change isn't entirely wrong, but it has the side effect of breaking MB display while in "stopped" state, where people are expecting to see the result of EXAM switch presses here, a documented behavior of the PDP-8/I. See p.93 in the 1967 edition of the Small Computer Handbook and page RIM-3 (PDF page 35) in the PDP-8 System User's Guide from 1969.

| 05:00 | SNAPSHOT: Beginnings of a script to build os8v3d-bin.rk05 Discovered that more work is needed in os8script.py to handle the dialog with the BUILD BOOT command: "WRITE ZERO DIRECT." Also the architecture for re-imagining copyins needs to be conceived. check-in: bec1348033 user: poetnerd tags: os8-v3f-extensions | |

| 04:03 | Apparently I never actually tested unset_option. Now It's working. tc08.mkos8 sets tc08 by default and unsets it if you specify td12k or tdrom on the command line. check-in: 02b01c97eb user: poetnerd tags: os8-v3f-extensions | |

| 04:36 | tc08.mkos8 now understand td8e as a common option to td12k and tdrom. Since we don't have a ROM config, we can't test tdrom, but the build of td12k with the common td8e stuff works. Still TODO: Further re-arrangement of mkos8 functionality. check-in: 50d5c66e31 user: poetnerd tags: os8-v3f-extensions | |

| 03:50 | Successful run of mkos8 head -o tc08 and mkos8 head -o td12k with the code for OS/8 scripting pulled out of mkos8 and put into lib/os8script.py Also a style pass was run on the names of things. Additional os8script methods have been added: configure_command which is an interface to the simh change commands and which allows on-the-fly setting of options. unset_option_command that allows unsetting of an option. I want the configure command so I can get rid of the "simh" command. I don't want to allow full scripting of simh. But I might be wrong here. I want to ability to set options inside scripts because the tdrom config is a variation on td12k, and I can set a common sub-option for the common bits now. TODO: test mkos8 system with the new library. TODO: Change the "change_" interface because we are repeating the describe code. We should "set" options rather than "change from x to y". The change interface requires fetching status twice, first to figure out what to do, and second, when calling the do_routines, to recheck inputs.

| 01:40 | Simplified the check for SIMH commands that transition from SIMH context back to simulation context: it was listing all of the possibilities exhaustively, except only in lowercase. Neither is required: we can list only the first letter in uppercase, then slice the first letter off of the command and uppercase it before searching this list. This is both faster and more reliable.

Then fill in the stubs for RX and console device work. check-in: d2167af791 user: poetnerd tags: os8-v3f-extensions | |
| 04:27 | Cleaned up external use of simh_context. The housekeeping boiled down to three locations: 1. Initialize to simh. 2. back_to_cmd sets simh. 3. The clever part: in send_cmd, look to see if the command being executed enters the OS, and if so set context "os8". TODO: RE-test os8-cp and all legacy mkos8 commands to make sure I didn't break anything. Then remove the context commands. The rule now is: Returning to simh leaves you in the simh context until you issue a boot, continue, or go command. check-in: 7b0047d2cc user: poetnerd tags: os8-v3f-extensions | |

| 05:22 | Ok, this is a bit gross. tc08.mkos8 now understands the td12k option, but it was a pain to get there. I had to create a simh command because we needed to disable dt and enable td. This also runs BUILD on os8v3d-patched.rk05 to switch from TC08 to TD8E drivers. It is very gross, but it does clean up after itself. (If it makes it all the way through.) This exploration has let me to believe that we might very well want to craft this as python code to, "Switch SIMH from DT to TD" and "Switch SIMH from RX01 to RX02". It is a mess of abstraction barrier violations to try and do it cleanly. So what we have now is a proof of concept. An icky one. check-in: 966fb1026b user: poetnerd tags: os8-v3f-extensions | |

| 06:30 | Taught mkos8 a new run command: Options. Now, before the mkos8 command arg, you can have options, for example "tc08". In the script file you enclose options in begin option foo end foo If the command line argument specifies -o foo, the lines are used. If not, they are ignored. Optional blocks can appear in commands with their own command processors, and can be nested. In this way a single command file can be used with variations on the same theme depending on which option is enabled. check-in: 10848363e5 user: poetnerd tags: os8-v3f-extensions | |

| 22:41 | The test intended to skip re-installation of all the SIMH binary media and the SIMH boot scripts on a system where that has already been installed was checking for the existence of os8.rk05, which will only exist on a system that had 2017.04.04 or earlier installed on it. A system that was fresh-installed from 2017.12.22 wouldn't have this file, so the *next* installation (say, to check out the trunk version) was overwriting local media and script files. This is not going to affect people who used only release versions unless they manually did "make install" again for some strange reason. The more likely way this hits is for someone who first installed 2017.12.22 and then later checked out an unreleased version and installed it over the top of their release version. check-in: 43161ac30b user: tangent tags: trunk | |

This is needed to get the rewritten mkos8 working. This version of the rewritten mkos8 uses tc08.mkos8 to successfully redo all the things that were in the "head" command to create a bootable tc08 DECtape. TODO: 1. Change head to do run_system on that file. 2. Add code to enable v3f-control.mkos8 to reproduce what the "v3f" command does. 3. Do the same thing with bin, patch, src.

Leader-trailer of 0200 and the 000 is added at the end. It will be interesting to see what kind of transformations are done on transfers into OS/8. Will the ^Z be added to .BN format?

| 07:01 | Had to turn parse_args back into a subroutine, because the new parse_action_file overrode the action_plan being created. Pulled back in some of the old main because I'll reuse that code when I implement the copying. Shifted some of the globals from the middle of the file to the section labeled for globals. BTW: The override by --action-file is because parse_args did two passes: 1. read names and glob them. 2. turn globbed names into actions. The action file is all actions. We override because that way I don't have to write code to figure out how to do a partial second pass of what's already been parsed from the command line when we hit the --action-file argument. Icky, but... check-in: f3702ec3c4 user: poetnerd tags: os8-cp | |

| 04:54 | Renamed os8-cp --tc to --dt, properly reflecting the SIMH device name. I see why it was called --tc, but it was incorrect to map it to SIMH device name "TC" (no such thing) and it's confusing to those of us who know the SIMH device names. Better to just remain consistent throughout. check-in: 7b2a875a1b user: tangent tags: os8-cp | |

| 21:03 | Merged in an upstream SIMH improvement to the throttle stabilization code which avoids recalibrating the throttle timers on re-entering the simulation either due to Ctrl-E/cont at the terminal keyboard or CONT/START on the PiDP-8/I front panel. It simply continues using the values it determined before the simulation was stopped; it will still recalibrate itself periodically, it just doesn't start over from zero. check-in: cac1e79178 user: tangent tags: trunk | |

| 22:09 | Modified the newly-created simh.os8_zero_core method to skip the top page of field 2, since it is reported that the OS/8 TD8E driver lives here. We don't use that driver in our current OS/8 disk distribution, but someone may later add that driver to their local clone of our software distribution then try running cc8-tu56-update (or some future script which also calls this new method) and be annoyed when their disk driver is MIA upon re-entering OS/8. check-in: 4b7c450799 user: tangent tags: trunk | |

| 12:29 | Updated ChangeLog check-in: 99c1dcabef user: tangent tags: trunk | |
| 11:38 | Replaced our reliance on the usbmount package — which only works out of the box on Raspbian Jessie and older — with a shell script based on https://serverfault.com/a/767079 which incidentally gives us the freedome to improve on it. check-in: d136804bf1 user: tangent tags: trunk | |
| 10:08 | Whitespace improvements to bldcc8.bi. It changes the order of files on the output tape for some reason, so cc8.tu56 is updated yet again. check-in: 2036c8a7b0 user: tangent tags: trunk | |
| 09:55 | Assorted improvements to the main CC8 manual. check-in: 5545137c62 user: tangent tags: trunk | |
| 09:49 | Renamed CC.BI to CCR.BI. OS/8 isn't terribly smart about figuring out which "CC.*" you meant when you say "EXE CC", so we need a prefix that doesn't conflict with CC8 output files. The new name means "Compile C and Run." It is definitely not a classic rock pun. Definitely. check-in: 20d1ed131d user: tangent tags: trunk | |
| 09:14 | Assorted improvements in src/cc8/examples/README.md to track recent developments in CC8 land. check-in: c598b55169 user: tangent tags: trunk | |
| 08:42 | Added bldcc8.bi and cc.c to the list of files we delete from the working RK05 disk from cc8-tu56-update, since they're also temporaries. Also reworked the way we're handling the Python lists to avoid problems with OS/8 command line length limits. check-in: 5d10912237 user: tangent tags: trunk | |
| 07:56 | Reworked the newly-deterministic cc8.tu56 creation in terms of Python lists so the code is easier to expand and the file lists are easier to read. Also improved the comments. Removed a pointless and possibly dangerous "DEL *.C" command which we no longer need now that we've given up on using wildcards in the COPY commands. There still remains some source of mischief because cc8.tu56 changed again purely by building it on a different platform. check-in: 32e4c2a446 user: tangent tags: trunk | |
| 06:59 | Comment improvements check-in: e8175ab22c user: tangent tags: trunk | |
| 03:00 | Fix for [ab0e67]: In addition to unmounting the dt image explicitly, one needs to clean out any files from previous runs of the script. The OS/8 copy actions send output in the order found on the input disk. The Linker resolves library items in the order the input files are found on disk. So we must remove anything from a previous run of the program, and SQUISH SYS: and DSK: so that successive runs of the script will cause input and output files to ALWAYS show up in the same order on the disk. When this is done cc8.tu56 DOES come up bit identical. This checkin is for the good script and the resulting good (canonical) cc8.tu56. check-in: 6f59c23708 user: poetnerd tags: trunk | |

| 04:56 | I am concerned that one needs to explicitly detatch dectapes before quitting the simulator. I have added that to cc8-tu56-update. I am pushing out the cc8.tu56 I built with this version. It corrects a corrupt LIBC.RL that was in the previous version. Alas, this version of cc8-tu56-update STILL does not create bit-identical tape images on successive runs. check-in: 599e310e0e user: poetnerd tags: trunk | |

| 14:34 | bosi init now kills off all processes for user 'pi' before usermodding it. Jessie didn't need this, but under Stretch, you have the "systemd --user" process and one other even after exec'ing yourself a pure root shell. check-in: 5b53879bca user: tangent tags: trunk | |

| 09:16 | Jonathan Trites found a use of '\*' in a call to simh.os8_send_cmd() which we missed when fixing these escaping issues a while back.

| 06:26 | cc8-tu56-update no longer copies basic.c to the tape image: the OS/8 compiler isn't currently able to compile it. check-in: 20a61bf4e6 user: tangent tags: trunk | |
| 06:25 | The CC8 cross-compiler now writes out *.sb instead of *.s to match the OS/8 file naming convention for SABR output, and to avoid the confusing use of *.s for some POSIX assembly languages. It was using *.s simply because it could replace *.c on the input file name with a single character replacement. If the input file name is exactly at the file name buffer's limit (20 bytes, including the trailing null), we still write out *.s rather that mess with resizing buffers or reserving one byte, complicating all the other uses of that buffer size. check-in: 857b3fafc0 user: tangent tags: trunk | |

| 03:21 | Steve Bennett's idea for redesigning our mkos8/auto.def option sharing mechanism so that it doesn't require modifications to autosetup.

| 02:28 | Updated SIMH to current upstream version. The only substantial change from our perpsective is working around a change they made to scp.h which redefines all of ctype.h, then changes their names, forcing any program that indirectly included scp.h to also link to scp.o! Broke that tie by carefully reworking our #includes to avoid bringing scp.h into programs like pidp8i-test which do not link to the rest of SIMH. check-in: 0b8fb3f7d8 user: tangent tags: trunk | |

| 16:51 | Extended the "skips" mechanism used in the "mkos8 patch" facility so that we can skip the FUTIL V7 patches when MACREL is being installed, since we know they will fail. Technically speaking, this change is not absolutely necessary since mkos8 was already smart enough to cope with the failure of the patch to apply, but we don't want end users complaining about "failed patches", not realizing that they are not expected to apply correctly when you do not give --disable-os8-macrel. check-in: faec308ed2 user: tangent tags: trunk | |

| 12:46 | No longer passing the PDP-8 simulator's MB register to set_pidp8i_leds() from within the CPU instruction dispatch loop.

| 09:16 | Rather than duplicate all of the option definitions and help texts between auto.def and lib/mkos8/argparser.py, we now generate lib/mkos8/opts.py from auto.def based on the options() values at the top of auto.def which mkos8's argument parser reads and uses to define most of its command line options, making a near-parallel of most of the configure script's --*-os8-*. This is on a branch because there are quite a few subtleties in all of this which means this feature needs more testing to be sure it is complete and doesn't break anything. So far, this change is a delta loss of 132 lines, a good sign that it's worth the complexity of doing things this way. Provisionally closes [f5d5cf50c4] and [68dae7cc88]. check-in: 9dcaed3c64 user: tangent tags: mkos8-option-dry-fix | |
| 07:21 | "make clean" no longer removes Makefiles generated from Makefile.ins. You now have to say "make distclean" to nuke those, along with all the other files that bring us back closer to a "fossil clean" state. check-in: 70dcfbc33d user: tangent tags: trunk | |
| 07:12 | Replaced hard-coded -DHAVE_DLOPEN=so CFLAGS option with one based on SH_SOEXT variable exported by autosetup, which allows SIMH to dynamically link to optional libraries such as libreadline on platforms that use a different dlopen(2) file name extension. Tested as not changing anything on Raspbian and as allowing command completion in SCP on macOS. Theoretically, it should allow use of DLLs on Windows, but this has not been tested; it probably only does so under Cygwin. check-in: 161b1c1b6b user: tangent tags: trunk | |

| 05:18 | After much testing I provide this new integration of MACREL: v2. Additionally I have updated os-patching.md to reflect current reality, and spun two sections from that doc into their own docs that cover macrel and the OS/8 V3D Device Extensions kit. MACREL v2 contains an update version of FUTIL that matches MACREL. That drove hand-integration of FUTIL patch 32.13.1M to get it working again under batch. The test program, RESORC, from the OS/8 V3D Device Extensions kit runs just fine when installed on SYS: but not anywhere else. I wailed on this problem for a while but could not find root cause. That version if RESORC is NOT installed. I'm just trying to understand what it is about that epoch of building that behaves in that unexpected way. check-in: c0e2d1ce56 user: poetnerd tags: trunk | |
| 04:46 | Regularized os8-* option help texts in auto.def and fixed tenses in verbs so they match the sense of the option's *inverse*, since that is how the help text is used in ./configure --help output. check-in: 09f9503302 user: tangent tags: trunk | |

| 20:20 | FUTIL V8A hangs under batch, and so it breaks our auto-build process as soon as we copy it in. I have hand-applied patch 35.13.1M which fixes the problem and upgrades FUTIL to v8B. I have documented work in README.TX, and I'm going to rename this image al-5642c-ba, a version never shipped, but embodying a critical fix. check-in: 86934ed2b1 user: poetnerd tags: trunk | |
| 17:20 | Adding a hand-tooled MACREL v2 DECtape image. Contains FUTIL.SV version 8a that should replace v7D to match new Core Control Block format used by the new MACREL. When FUTIL is replaced, we need to re-test and probably disable patch FUTIL-31.21.2M. check-in: 1d6f691bbc user: poetnerd tags: trunk | |

| 20:01 | Removed the test for lowercase 'y' in the reworked CC8 example calc.c: CC8 doesn't yet understand the C || operator. None of my other attempts to work around this work, either. (cupper, restructuring as nested if/elseif/else tests, etc.) check-in: 156b2b69e9 user: tangent tags: trunk | |

| 19:06 | Merged in trunk fix for SAVE SYS BUILD check-in: e29f5b239d user: tangent tags: cc8-fixes | |
| 17:38 | The "SAVE SYS BUILD" did the wrong thing. It carefully saved the updated setup on SYS which had been changed to the RK05, and then, moments later, overwrote it with the original from the DECTAPE. So we do "SAVE DTA0 BUILD" to put our revised setup where it will then be copied along with everything else to the RK05 SYS. check-in: 40a3f17c58 user: poetnerd tags: trunk | |
| 07:59 | First attempt at pep001.c. It builds and runs correctly under Clang, but it fails under CC8. check-in: 176f2cabcd user: tangent tags: trunk | |

| 07:31 | Reordered the commands in cc8-tu56-update to collect all of the "send file" calls together. There is some kind of timing sensitivity in all of this which caused the previous method to truncate some of the files or even leave them empty. check-in: 308b654b57 user: tangent tags: trunk | |
| 06:42 | All of the users of class simh which were using "expect" regexes like '\.' to wait for an OS/8 prompt had to be changed to '\\.' because the string is double-interpreted, first by Python in a string formatting construct (printf(), kinda) and then again in a regex construct, so that without the doubled backslash it was just looking for ., meaning any character in RE-speak. Did the same for '\*' because that was reducing to *, meaning "zero or more of the previous", and without a "previous", it matched anything. This doesn't seem to fix anything; I found it trying to fix something else, which I hope to check in soon. check-in: f8d7dc89bf user: tangent tags: trunk | |

| 08:54 | Reworked the CC[0-2].SV copy command in cc8-tu56-update so that it skips CCL.SV, thus avoiding the hole in the resulting DECtape image. check-in: d2f66e76b9 user: tangent tags: trunk | |
| 08:36 | Rewrote the code in mkos8 emitting DEL foo.SV commands as part of --disable-fortran-ii processing so that only one command goes to the simulator, which runs faster and logs nicer. check-in: ff1e1c0545 user: tangent tags: trunk | |
| 08:27 | Small Python style tweak check-in: 0db3c5fc38 user: tangent tags: trunk | |
| 08:13 | Giving --disable-os8-fortran-ii now leaves out LOADER, LIBSET, and SABR. Because the OS/8 version of CC8 depends on LOADER and SABR, it also implicitly sets --disable-os8-cc8. check-in: 648ea9921c user: tangent tags: trunk | |
| 07:11 | Running cc8-tu56-update on a Pi 3 gives a different result than running it on a macOS box using the *.s files produced on the Pi 3. Not sure why, but of the two, the result on the Pi 3 is more trustworthy, so using that one. check-in: 7d73c6e8e5 user: tangent tags: trunk | |
| 06:54 | Removed the getchar() call near the end of main() in the cc8 cross-compiler. It blocks cc8-tu56-update, and we don't want to add a "send CR" bit to the script just to placate it. check-in: 96b6cef0c3 user: tangent tags: trunk | |
| 06:50 | Fixed COPY commands near the end of cc8-tu56-update: they weren't grabbing everything we thought they should. Also removed CCL.SV, inadvertently copied to the tape by the CC?.SV pattern. check-in: 0eaba4e478 user: tangent tags: trunk | |
| 06:33 | Initial version of tools/cc8-tu56-update complete, which updates media/os8/subsys/cc8.tu56 from the contents of src/cc8. The latter is now much smaller than before, since we no longer include the intermediate files: all *.SB and most *.RL. The only exception is LIBC.RL, which the linking step needs when building end-user programs. check-in: 4e67bbdfaf user: tangent tags: trunk | |
| 06:30 | Rewrote src/cc8/examples/calc.c for clarity. It could be better, but it doesn't build and run properly as-is, so I've stopped here, waiting for improvements to the C compiler. check-in: 832db28e22 user: tangent tags: trunk | |

| 06:24 | Reverted the LF -> CRLF change in media/os8/init.tx.in, since autosetup just reverts it when creating init.tx. Instead, modified txt2ptp to turn LF input into CRLF output. I chose this instead of running a "dos2unix" type program on the files from simh.os8_send_file() because there is no standard for the name of such a program. Since our txt2ptp filter has to be involved anyway, we might as well give it the job. check-in: 6653eac20e user: tangent tags: trunk | |
| 06:06 | Reworked the stock init.tx.in file to use lowercase, now that it's allowed, and to have DOS line endings now that it's being copied in as-is, rather than filtered through mkos8, which implicitly converts the line ending style. check-in: 93f3beed61 user: tangent tags: trunk | |
| 06:01 | Rewrote simh.os8_send_file in terms of txt2ptp and SIMH paper tape attachment and read-in. It's faster, it works with much larger files, and it doesn't fold lowercase input. check-in: 69766295e7 user: tangent tags: trunk | |
| 04:35 | The top-level "run" target no longer depends on the build RK05 media because we need to be able to use it to run whatever's built, even if it's technically out of date. The thing we're working on now modifies the RK05 disk images, and we need to then be able to say "make run" to examine what it did without having the work overwritten. check-in: b4e684c40a user: tangent tags: trunk | |
| 03:49 | Moved another part of the "send file to OS/8" process from mkos8 to simh.os8_send_file(). check-in: 12dd946f7a user: tangent tags: trunk | |

| 23:28 | Fixed some code in the #include handling of CC8 which relied on undefined behavior.

| 23:18 | Added a redirect-to-top[ Makefile.in to src/cc8/os8, since you have to be cd'd into that directory to build the OS/8 compiler, so you want to be able to say "make" from there. check-in: a388b49124 user: tangent tags: trunk | |

| 04:43 | The method we were using for comparing lz4-compressed RK05 disk images in test-mkos8 only works if lz4 on the generating system and the test system give the same output for the same input, but this appears not to be the case between macOS 10.12 and Raspbian Stretch, likely due to improvements in the compression algorithm or compression defaults between the two versions in use. Therefore, instead of doing a binary comparison of the rklz files, we now decompress the rklz files and compare those outputs using a new tools/cmplz script which test-mkos8 calls. check-in: 8d51be13c7 user: tangent tags: trunk | |

| 06:21 | Merged in trunk changes. The original reason for this branch just disappeared, to be replaced by a new one: the test results can only be compared between two identical checkins because of the INIT.TX file, but that just means we now need to use this branch to pin a particular version in place. Thus, we might as well bring the recent trunk changes in and start again. With test-mkos8 -es, we don't need to regenerate the entire test corpus to learn useful things. check-in: 111c244601 user: tangent tags: test-mkos8-pinned | |
| 05:55 | test-mkos8 saves the mismatched rklz file if the test doesn't pass check-in: 2147ab88c0 user: tangent tags: test-mkos8-pinned | |
| 05:07 | Renamed test-mkos8 -s option to -1 and implemented -e and -s, which together allow Monte Carlo testing on a subset of the test corpus. This is on a branch because the current test corpus was generated before the change to 3-column DIRECT output in generated OS/8 disk images, which changes the disk contents and log contents. Thus, we need to do this development on a branch stemming from the last checkin before that change and any possible later ones, until we're ready to regenerate the test corpus. check-in: 47217f7552 user: tangent tags: test-mkos8-pinned | |
| 04:20 | Fixed a bug in the way teco-pi-demo was starting the simulator introduced along with the recent "ignore GPIO lock failure" stuff for mkos8. check-in: c0788fcd5c user: tangent tags: trunk | |
| 04:05 | Made second parameter to class simh's ctor optional, as the comments claim, so that teco-pi-demo will run again. check-in: 846340d3d1 user: tangent tags: trunk | |
| 02:30 | The new "throw exception on GPIO failure" feature added to prevent teco-pi-demo from colliding with other simulator users broke mkos8 under the collision case. (Not otherwise.) It is now possible to tell class simh whether this condition is considered fatal or not. check-in: 7e16fe3b23 user: tangent tags: trunk | |
| 02:17 | Added a #include to src/d8tape/d8tape.h to placate the GCC on Raspbian Stretch. check-in: 17be5b5dd8 user: tangent tags: trunk | |
| 02:16 | Integrated Robert Krten's d8tape host-side disassembler. It is the version distributed [here][1] with the following changes: 1. A trivial warning-squishing change 2. Using our own build system instead of the given `Makefile`. This also means no automatic version number bumping. 3. The `LICENSE` file is replaced with `src/d8tape/LICENSE.md`, containing the salient content of a private email message from Robert Krten granting more liberal use of the program than in the original license. [1]: http://dustyoldcomputers.com/pdp-common/reference/host/ check-in: 24d387ee4e user: tangent tags: trunk | |
| 01:25 | Added "SET TTY COL 3" to mkos8 to give 3-column DIRECT listings, like the old os8.rk05 did. This checkin will cause a binary change to all RK05 bin disks created by mkos8; thus the new tag on checkin [fe441b85b]. check-in: 676330e2d9 user: tangent tags: trunk | |
| 00:58 | The icky "sleep" call in teco-pi-demo wasn't long enough to always fix the SIMH "cont" problem. Doubled it; we'll see if that fixes it in all cases. check-in: 95df7e245b user: tangent tags: trunk | |
| 00:44 | Class simh now throws an exception when the GPIO is locked at simulator start time. If this happens, teco-pi-demo exits with an error and mkos8 just grouses a bit; the difference being, teco-pi-demo really needs the display and mkos8 really doesn't. Applying tag "test-mkos8-mark" to this release because a change a bit down the timeline breaks all of the test-mkos8 outputs so far, so we need to be able to return to this checkin symbolically until we're done using that test corpus. check-in: fe441b85b4 user: tangent tags: trunk | |

| 04:53 | Replaced the broken calculation for simh._kbd_delay with a new one based on the new pidp8i.ips module, potentially modified by teco-pi-demo -b. The previous version had a Python bug in it that caused no delay at all to be applied between OS/8 keystrokes, which probably means it would only work reliably on sufficiently fast host machines. This one doesn't change the per-test build time all that much, but it will add increasing amounts of keyboard delays on slow hosts, as is appropriate. check-in: 2211503b72 user: tangent tags: trunk | |

| 02:14 | A short document providing help with our FORTRAN IV stuff. check-in: a4a06ba896 user: poetnerd tags: trunk | |
| 02:00 | Subsetted the INFILES list in Makefile.in to segregate the set that requires a mkos8 re-call from those that merely cause a reconfigure and build. As the INFILES list grew, more and more files irrelevant to mkos8 were included, increasing the chances of a pointless mkos8 build. check-in: c0987c9ee3 user: tangent tags: trunk | |

| 15:23 | Updated TODO section in ChangeLog.md check-in: 1e64c48994 user: tangent tags: trunk | |
| 14:20 | test-mkos8 now builds and keeps os8v3d-patched.rk05 when not configuring with --disable-os8-patches. Previously, it was building and keeping the -bin disk regardless of this configuration option. check-in: e1a78b7930 user: tangent tags: trunk | |
| 04:22 | mkos8 contains in-line code to replace FORLIB.RL with the patched one on local.tu56. os8-patching.md documents this new state of affairs. check-in: 1fbbf7a508 user: poetnerd tags: trunk | |
| 03:19 | Added the 3 FORTRAN IV Source DECtapes. They came from Dave Gesswein's Archive, pdp8.net under misc_dectapes. The sources I've built seem reasonable. The DECtape part numbers match those for OS/8 V3D FORTRAN IV from the DEC Software Catalog. TODO: Write up what we have for FORTRAN IV in a doc file. check-in: a8ba68ef88 user: poetnerd tags: trunk | |
| 03:14 | Updated Fortran IV install: Move the tapes to the subsys directory. Tape #2 is not needed. It contains the source files for the FORLIB.RL run time library. TODO: Add in the source DECtape images to the repository. check-in: 16d14955b5 user: poetnerd tags: trunk | |
| 03:12 | Added files necessary for mkos8 to integrate patch FORLIB-51.10.1M.patch8. As per instructions in that patch, a new DLOG.RA has been made with one source line change. DLOG.RA was assembled with RALF into DLOG.RL. LIBRA was used to make an updated FORLIB.RL DLOG.RA and FORLIB.RL are on local.tu56. DLOG.RA in the patch directory is a redundant copy of that file. TODO: Add logic in mkos8 under patches to replace FORLIB.RL with the updated one if BOTH with-os8-fortran-iv AND with-os8-patches are set. check-in: 87aa1be986 user: poetnerd tags: trunk | |
| 02:34 | Discovered a typo in the patch, AND that some OCR mistakes had been missed. Both are fixed now. TODO: Codify this patch into something mkos8 can work with. check-in: 69ce06acaf user: poetnerd tags: trunk | |

| 09:17 | With the final (?) bugs squished in the parallel version of test-mkos8, merging it into trunk. check-in: 4fc0e64aff user: tangent tags: trunk | |
| 09:16 | Fixed a path bug that caused test-mkos8 to write finished test results to the wrong directory. That in turn caused subsequent runs to re-do tests already completed because the results weren't where it expected to find them. Closed-Leaf check-in: b513069b4c user: tangent tags: parallel-test-mkos8 | |
| 09:15 | Added test-mkos8 -v flag, enabling several new messages that explain what it's about to do. check-in: dad526a6ff user: tangent tags: parallel-test-mkos8 | |
| 08:54 | Fixed the last few problems preventing test-mkos8 from running multiple builds in parallel. check-in: db37af582e user: tangent tags: parallel-test-mkos8 | |
| 08:47 | Though we hacked tools/version to make it print a dummy version string when running under tools/test-mkos8, it didn't exit afterward, so it continued to run the code that was causing the problem we added the workaround to avoid! check-in: 3213505810 user: tangent tags: parallel-test-mkos8 | |
| 08:41 | The bootable-*.tu56 copy of the OS/8 boot tape created by mkos8 to avoid modifying input media is now being created in dirs.os8mo instead of os8mi, since the latter is shared among the children of test-mkos8, which means that when one of them deletes their temporary copy of this file, the copy used by all of them gets deleted. The file, being volatile, must go into each child's build directory. check-in: 0e8e159cf5 user: tangent tags: parallel-test-mkos8 | |

It doesn't show stats for files that don't exist on the release branch, only for files in common between the two, due to the limitations of the diff format. check-in: f4025603f4 user: tangent tags: trunk | |

| 05:16 | Extended module search path for teco-pi-demo the same way we did some time back for mkos8 so that when building out-of-tree, it doesn't go looking for autosetup-written files like lib/pipd8i/dirs.py under @srcdir@. check-in: fdc0fa387c user: tangent tags: trunk | |
| 05:14 | Reworked the dirs.py module so that dirs.media now points to the "media" directory only, not to "media/os8". Then added dirs.os8mi and dirs.os8mo for the mkos8 input and output directories, respectively, and adjusted mkos8 and teco-pi-demo accordingly. check-in: 6e102afa3a user: tangent tags: trunk | |
| 04:54 | Using dirs.os8 instead of dirs.media in teco-pi-demo, and fixed the "make install" step that adjusts libs/pidp8i/dirs.py in the installation tree to allow this to work. check-in: aa66ed7ae9 user: tangent tags: trunk | |
| 04:41 | teco-pi-demo now seeks out the os8v3d-bin.rk05 disk intelligently, using the one in bin when run from a development tree, else using the one in dirs.media if run from the install tree. check-in: 2f68149c21 user: tangent tags: trunk | |
| 04:33 | Replaced most of the command output from "make install" with echo calls explaining what each step does. check-in: 37cd3f3b62 user: tangent tags: trunk | |
| 04:26 | More adjustments to "make install", primarily getting teco-pi-demo installed by generalizing the steps we were previously taking for the bin/pidp8i script. check-in: c24e154589 user: tangent tags: trunk | |
| 04:16 | Assorted fixes to "make install" for the out-of-tree build case. check-in: 2204c9f1d5 user: tangent tags: trunk | |
| 03:36 | One of the steps in "make install" didn't get updated when moving the cc8 tree under src. check-in: 4b75bd0c36 user: tangent tags: trunk | |
| 03:15 | One of the changes in [2d6184c3c9] moves "src" to the end of the directories processed by mkadrules at configure time, but mkadrules itself was writing another version of the "src" rule set to the beginning of adrules.mk for the out-of-tree case, which also needs to move to the end of the file for the same reason. check-in: a658bdb074 user: tangent tags: trunk | |
| 03:06 | Removed -w flag for src/PDP8/*.c: turns out to be unnecessary on Clang 9.0.0 (macOS 10.12) and GCC 6.3.0 (Raspbian Stretch). If later testing shows a need for something like this, we should probably put back -Wno-foo flags instead on a case-by-case basis. Turning off all warnings was an overreach. check-in: b54c70e41b user: tangent tags: trunk | |
| 03:01 | palbart now builds with -g or -O2, depending on the --debug configure script flag. check-in: 2bee0290e3 user: tangent tags: trunk | |
| 02:58 | Reworked the CFLAGS option handling so that we don't use the CFLAGS made for pidp8i-sim, which are entirely inappropriate for the cc8 cross-compiler. check-in: 3731a81320 user: tangent tags: trunk | |
| 02:44 | Moved cc8/* under src, as we recently did for palbart. check-in: 2d6184c3c9 user: tangent tags: trunk | |

| 00:12 | Changed all "<a name" tags to "<a id" in README.md: strictly speaking, the "name" attribute isn't legal any more in HTML5, though all browsers still understand it. We've taken to using "name" only for fragment aliases, with "id" being the primary identifier. check-in: 6571cc1290 user: tangent tags: trunk | |
| 00:02 | Added tools/publish-os8, which publishes bin/os8v3d-*.rk05 as unversioned files, so that people not running the current PiDP-8/I software can download the RK05s generated by mkos8. check-in: 3542ea0c36 user: tangent tags: trunk | |

| 03:52 | Added a commented-out "set remote telnet=3141" SIMH command to teco-pi-demo so that those wanting to fiddle with the simulator while the demo runs can do so without reading the SIMH manual. Whether they'll read the code and avoid bugging me about it is an open question. check-in: 86214e8626 user: tangent tags: trunk | |
| 03:50 | Increased the number of digits to calculate in teco-pi-demo to the maximum value that doesn't crash TECO8, determined by experiment. This ensures that the demo runs as long as possible, so users don't have to keep restarting it. With the prior value, that would have happened after about 2-3/4 years, not unreasonable for a PiDP-8/I running purely as an objet d'art. check-in: 2d4085c0b4 user: tangent tags: trunk | |
| 01:05 | Put args.debug stuff back into mkos8, reverting part of [9663cf4b750]. Not sure why it was failing on Bill's machine, but it works here. check-in: 81f6f42e86 user: tangent tags: trunk | |

| 20:49 | Discovered that PAL8-21.22.4M analogously to ABSLDR-21.29.1M, is actually against the OS/8 V3D Extensions version, and BREAKS PAL8's ability to generate listing output. That problem is now documented and the patch is disabled. check-in: 3e3e10993f user: poetnerd tags: trunk | |

| 18:53 | There was a typo: ".GET SYS TECO" was ". GET SYS TECO" The patch failed to load TECO into core, but happend to have TECO in core from the previous patch run. I guess I should make "failed OS/8 command parse" a fatal error. check-in: f410b7a38a user: poetnerd tags: trunk | |
| 16:54 | Added "patches" item to the ChangeLog. check-in: d26180a507 user: tangent tags: trunk | |

| 16:23 | Removed an unused function from mkos8, and did some whitespace and comment tweaks. check-in: 4a64ffe7ce user: tangent tags: trunk | |
| 16:01 | Suppressed most of the ODT/FUTIL patch application debugging messages in mkos8 by default. Added a --debug flag to re-enable them. This is distinct from --verbose in that the latter swaps the SIMH logging from sending to a log file to sending to stdout, which in turn suppresses most other output from mkos8. We might want to rethink these two options, combining them somehow to avoid the new confusion. check-in: 66b56643e4 user: tangent tags: trunk | |
| 15:36 | Added configure --os8-patches flag, default on. When set, calls "mkos8 bin patch" instead of just "bin". check-in: adaef3c96e user: tangent tags: trunk | |
| 15:06 | Merged mkadrules branch into trunk: all the .c.o and .c.d rules are generated at configure time instead of being hand-maintained in Makefile.in. This also moves the CC8 *.[od] files to obj/cc8/cross, mirroring the source tree structure. This simply removes an idiosyncratic difference between the previously hand-maintiained rule sets, a natural outcome of generating them from a single template rule set. check-in: cdd09a6093 user: tangent tags: trunk | |
| 14:57 | Reverted delegation of creation of the obj subtree dirs to mkadrules: better done by extending BUILDDIRS in Makefile.in. Closed-Leaf check-in: c2bc715e2c user: tangent tags: mkadrules | |
| 14:40 | Deferred relacement of "SRCDIR" in mkadrules until the last moment in case we're building out-of-tree and $srcdir contains "src/" to avoid unintended string replacements. check-in: d74f2616c5 user: tangent tags: mkadrules | |
| 14:26 | Fixed a command line sanity check in mkadrules for the out-of-tree build case. check-in: 72986ccf05 user: tangent tags: mkadrules | |
| 14:21 | Minor improvements to the .o and .d generation and cleanup bits in Makefile.in. Not really related to the mkadrules mechanism, but I noticed the weaknesses while working with it. check-in: 4768cc8794 user: tangent tags: mkadrules | |
| 14:10 | Reworked CC8_OBJS to work with new mkadrules obj subdirectory scheme. check-in: 1ba04c2424 user: tangent tags: mkadrules | |
| 14:08 | Switched from mkdir() to make_path() in previous to allow obj/cc8/cross to be created. Like mkdir(1), Perl's mkdir() won't recurse. check-in: 18d508e685 user: tangent tags: mkadrules | |
| 13:57 | Moved generation of obj/* subdirs to mkadrules from auto.def. check-in: 5325bc575b user: tangent tags: mkadrules | |
| 13:49 | The repeated autodependency .c.o and .c.d Makefile rule sets are now generated as adrules.mk by tools/mkadrules, which will avoid the sort of regression fixed in [83b73930ec]. check-in: a818a27648 user: tangent tags: mkadrules | |
| 12:11 | The changes in [a6c3123bff] to the obj/PDP8/*.o Makefile rules to allow out-of-tree builds caused dependency ordering problems on the Pi, though not on macOS for some reason. The prior fix did not change all obj/*.d type paths to obj/PDP8/*.d, which confused the autodep mechanism. Problem noticed by Phillip Porch on the mailing list, with a provisional patch, extended by me. check-in: 83b73930ec user: tangent tags: trunk | |
| 03:58 | mkos8: Close patch files when done with them. (minor housekeeping oops) Rudimentary FUTIL support now supports the 4th PAL8 patch. Discovered the ABSLDR patch supplied is just wrong. It's for a version of ABSLDR we don't have and which exists on the OS/8 V3D Device Extensions kit, which is rare, and not yet visible in the archives I've scoured. TODO: 1. MACREL and LINK patches. 2. Decice what to do about the patches that require very different application: FORLIB 51-1-01M is a source patch that would require a batch script. Same with OVDRV 40.6.1M. LQP 21.49.1 runs BUILD in a batch script which is actually not possible unless you have the version of BUILD unique to the OS/8 V3D Device Extensions kit. check-in: 241d6b4a25 user: poetnerd tags: trunk | |

| 16:32 | Made the "get version string" mechanisms more durable in the face of multiple parallel instances, as now happens with parallel test-mkos8. check-in: c34a426eed user: tangent tags: parallel-test-mkos8 | |
| 15:49 | First pass at reworking mkos8-test to run $cores tests in parallel unless -s is given. Each test is built out-of-tree in test/tmp/$PID, so they don't interfere with each other. check-in: f5cad8d9f6 user: tangent tags: parallel-test-mkos8 | |
| 15:24 | Switched compression in test-mkos8 from lzma to lz4. check-in: 6addfa56e1 user: tangent tags: trunk | |
| 15:02 | Got out-of-tree building again with mkos8. check-in: a6c3123bff user: tangent tags: trunk | |

| 10:29 | First version of the combinatoric tester. Implements [87abba4c08]. check-in: def9c30e0f user: tangent tags: trunk | |
| 07:57 | Applied the reverse fix to the previous checkin: when built for ILS and previously running with ILS suppressed, then switching from "ratio" throttle mode to an "IPS" throttle mode, re-enabling ILS. check-in: 141f201e85 user: tangent tags: trunk | |
| 07:48 | Merged NLS forcing in SET THROTTLE M/N mode (ratio mode). Closes [7d7eadd391] check-in: 3f1588e495 user: tangent tags: trunk | |
| 07:47 | The mechanism we were reusing to revert to NLS mode while built for ILS wasn't doing full-rate display updates. It didn't need to before because it was only used for STOP and single step/instruction mode. Now that we're also using it for SET THROTTLE=M/N (ratio mode) it differed substantially from "real" NLS mode prior to this fix. Closed-Leaf check-in: 1d600ecbe7 user: tangent tags: ratio-throttle-ils-disable | |
| 06:51 | Accidentally made a fix in the *.in output file, checking in the buggy version. check-in: f219177758 user: tangent tags: ratio-throttle-ils-disable | |
| 06:48 | First step toward disabling ILS when SET THROTTLE M/N is set. check-in: 70f50d2061 user: tangent tags: ratio-throttle-ils-disable | |
| 06:38 | The line to remove a prior sullied bootable OS/8 TU56 tape image in make_bin() within mkos8 wasn't checking whether it exists first. Calling os.remove() on a file that doesn't exist throws an exception, killing the program. (Clearly we two haven't been running without this file always existing from a prior run for quite some time, or have been missing this failure!) check-in: 1e62781bcd user: tangent tags: trunk | |
| 05:47 | Finished pass through UWFD. The supplement is therefore "done" for now. check-in: fcbd2f669a user: tangent tags: trunk | |
| 05:44 | Added "FOCAL Statement Functions" section to the supplement. check-in: 2348b30f17 user: tangent tags: trunk | |
| 03:14 | Basic patching with ODT works. First two Patches to EDIT.SV as requested in patches/patch_list.txt are applied correctly. TODO: Try more ODT patches. Implement support for "R EPIC" and "R FUTIL" check-in: f382a12204 user: poetnerd tags: trunk | |
| 02:39 | The bin/*.pt generation build rule added for examples/*.fc conflicted with the preexisting ones for asm/*.pal and examples/*.pal, which also produce bin/*.pt. (Conflicted twice in fact: once at the make(1) level and again in the output when the basename is the same. Consider examples/pep001.{fc,pal}.) Addded -focal and -pal tags to the output *.pt file names to break the conflict. check-in: e9954d80c5 user: tangent tags: trunk | |

| 02:58 | Fix bug in handling of "all": The "all" action should not be one of the things acted upon. Now we have "allowed acts" and "do_all_acts" that just has src and bin. Begin work on the patch maker: A manifest file will list the patch files. For each patch file, parse it and act on it. Parsing the patch file is fun! Create a degenerate state machine to control what we do when we're in a command. ODT is currently parsed.

| 13:45 | Discovered a new Autosetup feature, write-if-changed. Rewrote the mkos8.opts mechanism for suppressing RK05 rebuild if the mkos8 options haven't changed in terms of it. Much shorter and clearer now. check-in: 26e5f1c5ee user: tangent tags: trunk | |

| 11:33 | Raised new simh class to a single-module library as well. check-in: 6837a49441 user: tangent tags: trunk | |
| 11:26 | Moved lib/mkos8/argparser/__init__.py to lib/mkos8/argparser.py. We don't need the extra directory layer: argparser isn't going to turn into a multi-module sub-library. check-in: 58babeb8b1 user: tangent tags: trunk | |
| 11:22 | Moved the dirs.py module out of lib/mkos8 into a new lib/pidp8i directory, since it really isn't mkos8 specific. (A later checkin will include another program that also uses it.) check-in: d66f92ce95 user: tangent tags: trunk | |
| 11:09 | Extracted class "simh" from mkos8 to collect all of the functions that call pexpect either to command SIMH or OS/8 *via* SIMH. Also threads that object instance through the mkos8 call chain instead of having everyone refer to a global, and cleans up the function naming to be a bit more self-consistent. check-in: 2af351187f user: tangent tags: trunk | |
| 10:06 | Found documentation for FRA() check-in: ffeac8fad3 user: tangent tags: trunk | |
| 09:45 | Added the "Command Overloading" section to the U/W FOCAL supplement. Added a top-level LIBRARY command section, as well as LIST and LOGICAL sections. Also moved the ZVR and FRA sections up to be just after these, as the group amounts to documentation of commands and functions not covered in The Manual. check-in: ad0e316bcd user: tangent tags: trunk | |

| 23:36 | Small tweaks to previous check-in: 0ed7d97637 user: tangent tags: trunk | |
| 23:28 | Added a new section to the supplement, "The Paper Tape Reader", showing how to pull FOCAL programs in from simulated paper tape. Also created a mechanism similar to the examples/*.pal -> bin/*.pt, only for examples/*.fc by way of Bill's txt2ptp program. The new supplement section is written in terms of this mechanism, using a new example program, tratbl.fc. check-in: 964c647879 user: tangent tags: trunk | |

| 13:45 | Decided to just remove "The Hard Way" from the U/W FOCAL manual supplement. Should a good idea for using a text editor on a FOCAL ASCII text file come up, we can pull the text back from Fossil and work it back into the doc. check-in: 4842ad6f5a user: tangent tags: trunk | |

| 13:15 | Factored "instdirs" target out of "install" so mediainstall can depend on it. Without this, you could type "make mediainstall install" and it would fail because the instdirs hadn't been built yet. This removes the need to care about the order of targets given. check-in: a631363b48 user: tangent tags: trunk | |
| 13:07 | Corrected new ChangeLog item about the -src RK05: it's built from 10 tapes, not 7. check-in: cc1d46e7c3 user: tangent tags: trunk | |
| 03:34 | Tiny nomenclature change: "DEC source tapes" would imply building from source. So the binary RK05 image was, in meticulous nomenclature built from, "DEC binary distribution DECtapes." Similarly "distribution DECtape(s)" was added further down the doc as appropriate. check-in: b2707f406f user: poetnerd tags: trunk | |

| 01:13 | Reworked "make run" so that it runs OS/8 from bin, not the installation directory, so you don't have to "make install mediainstall run". check-in: 6d1cdc8426 user: tangent tags: trunk | |

| 22:49 | Forgot to install the adventure setup file, ADVENT.IN on advent.tu56. So it kept thinking it was uninitialized. With that file in place, the code to run the dialog is no longer needed. I commented it out of mkos8. TODO: Delete the dialog code. check-in: cb498b03ba user: poetnerd tags: trunk | |

| 17:35 | Merged cc8-merge branch into trunk. This is happening after the merge of clean-os8-packs since the latter resolves the question of how we're going to merge Ian Schofield's nice and clean OS/8 installation + C with our previous os8.rk05. This merge therefore just gets us an alternate OS/8 bootscript and disk image plus the host-side compiler. check-in: 4fa2e4fdc0 user: tangent tags: trunk | |

| 05:18 | Updated some doc URLs to point to the trunk branch now that clean-os8-packs has been merged in. check-in: 01dff30411 user: tangent tags: trunk | |
| 05:17 | Updated the ChangeLog to distill what's happened since v2017.04.04. We're not all that near a release point, but with the merging of clean-os8-packs into the trunk, it felt like a good time to summarize what's been happening these past few months. check-in: 854f35ecb6 user: tangent tags: trunk | |
| 03:19 | mkos8 now runs Adventure after installing it to answer the configuration questions it asks on first run, since we know the answers and the user is more likely to be fine with our answers than they are able to answer differently *and* correctly on their own. check-in: 880632ab80 user: tangent tags: trunk | |

| 18:46 | Merged clean-os8-packs into trunk. check-in: faee651fc4 user: tangent tags: trunk | |
| 18:44 | Replaced the "Hello, world!" init message with one based loosely on the "FIELD SERVICE PDP-8 DIAGNOSTIC SYSTEM" message, but showing information more likely to be useful to our end users. Closed-Leaf check-in: e95de3f1a6 user: tangent tags: clean-os8-packs | |
| 18:16 | Sketched in the initial implementation of the --enable-os8-init feature, which creates INIT.TX and INIT.CM on the OS/8 bin disk just before finishing up. If the option is set, it calls SET SYS INIT to make it run on boot, but it always does get created, so the user can turn it on later without rebuilding their bin disk. This version just says "HELLO, WORLD!" We'll be doing something more substantial next. check-in: 3f8551641f user: tangent tags: clean-os8-packs | |
| 17:52 | Added mkos8 to the set of files ctags -R looks at, since it won't normally find it, lacking known file extension. check-in: e165816404 user: tangent tags: clean-os8-packs | |
| 17:34 | Whitespace and comment tweaks check-in: f3dceaeb79 user: tangent tags: clean-os8-packs | |
| 16:31 | The creation of obj/mkos8.opts during the configure script run to force a rebuild of the OS/8 media *only* when those options have changed was failing in clean build trees because obj doesn't exist yet. For the most part, $(BUILDDIRS) in the Makefile handles this, but that hasn't run by this point, so we need to do this one early. check-in: 5dfc456436 user: tangent tags: clean-os8-packs | |
| 05:30 | The "?01.00" error code in the reformatted refcard is just "?" on the original, so there is not in fact a discrepancy between the two error tables for this one.

| 18:27 | Documented why we're giving *.FD in OPEN INPUT commands. check-in: 96c92dd0b3 user: tangent tags: clean-os8-packs | |
| 18:24 | Changed the *.FC and *.TX extensions in the supplement's newly reorganized "Loading and Saving Programs" section to *.FD. *.FC is a binary FOCAL core image format, not suited for plain text. That's what *.FD is for. *.TX is also fair, but FOCAL defaults to FD, so we might as well go along with it. check-in: ea76f85801 user: tangent tags: clean-os8-packs | |
| 18:18 | Reorganized all the program loading and saving material in the supplement as subsections of a top-level section, ordered them in increasing level of complexity (and probably decreasing usefulness!).

| 14:09 | The "copyright" paragraph in the refcards doc used to be at the end and thus said "above text", but that was not changed when moving it to the top of the document. Also, USA -> United States; it flows better. check-in: d20062edad user: tangent tags: clean-os8-packs | |

| 12:51 | Fixed up a few remnants of the brief CARD*.DA presence in the supplement check-in: 220c9a54da user: tangent tags: clean-os8-packs | |
| 11:33 | Merged scanswitch serial mod fix in from trunk check-in: dce9086a45 user: tangent tags: clean-os8-packs | |
| 11:26 | Removed a bunch of the init code from scanswitch.c: calling the new gpio-common module init functions instead. If nothing else, this allows scanswitch to work correctly for the serial mod cases for the first time! check-in: c5a2a1eb11 user: tangent tags: trunk | |
| 11:25 | Moved more of the gpio-common module's internal init code out as public functions, and hid away some of those now only called from within the module. check-in: fc42d83843 user: tangent tags: trunk | |
| 11:01 | Extracted init_pidp8i_gpio() from gpio_thread() startup so we can call it from programs that don't use the GPIO thread. check-in: 2a8b622469 user: tangent tags: trunk | |
| 09:41 | A bit of messing with CSS and paragraph breaks in the new uwfocal-refcards.md file to get somewhat reasonable print output. Still not awesome, but better than it was. check-in: e365c158fb user: tangent tags: clean-os8-packs | |
| 09:13 | Moved the CARD[1-4].DA material from uwfocal-manual-supp.md to a new uwfocal-refcards.md file to keep the copyrights clear, and to make printing easier. check-in: ad35229d5c user: tangent tags: clean-os8-packs | |

| 08:30 | Clarified Bill's new "Loading and Saving Programs" WRITE-based ASCII file saving method in the U/W FOCAL supplement. Also moved some paragraphs that were up in this section down in the CARD2.DA section where they clearly belong, and explained the source of these CARD files in the License section. check-in: f315cb560c user: tangent tags: clean-os8-packs | |

| 20:32 | Added DCP Disassembler to packs. Does this by default. I sort of don't like how you have to touch 3 files in 3 places to add stuff to the packs. check-in: a60baa0fb2 user: poetnerd tags: clean-os8-packs | |
| 20:05 | Realized that the "&/" variable name U/W FOCAL mangles "foo" into cannot be the secret & variable because that isn't allowed by default. On further investigation, it appears to be some kind of value mangling, so fixed that discussion in the U/W FOCAL supplement. check-in: d2947f1527 user: tangent tags: clean-os8-packs | |
| 20:03 | Converted install of Case conversion, chess and vtedit to file-based subset copyin from local.tu56. This structure is what would be used for the DCP16/DCP24 disassembler copyin. check-in: 7d045ed598 user: poetnerd tags: clean-os8-packs | |
| 19:55 | Explained why U/W FOCAL gives an answer of "0" instead of an error from fsin(pi/2), and explained why this is a sensible answer given the historical context. check-in: a057be2ab4 user: tangent tags: clean-os8-packs | |

| 19:29 | Added the Improvements sub-section to the "Default Output Format" section of the U/W FOCAL supplement. check-in: e12e3f1e57 user: tangent tags: clean-os8-packs | |
| 19:17 | Now that we have a fully-functional version of FOCAL, updated several of the commands and outputs in the F??? sections to be actual terminal transcripts. Also added point 7 to the Formatter's Note explaining why this Markdown version of the manual doesn't show the inputs and outputs exactly the same way the original did. check-in: 3bdcd2ac8f user: tangent tags: clean-os8-packs | |
| 19:03 | Added a "Default Output Format" section to the U/W FOCAL manual supplement to explain why some of the examples' outputs in the manual are not particularly nicely formatted. check-in: 00d620ff6c user: tangent tags: clean-os8-packs | |
| 18:09 | Grammar tweak check-in: 23fdc81ed1 user: tangent tags: clean-os8-packs | |
| 18:08 | Clarified the 3 points at the top of the U/W FOCAL manual supplement justifying its existence. The prior-numbered points 1 and 3 might have been read as the same point repeated, whereas now it's clear that we're making two distinct points. check-in: c823d49f60 user: tangent tags: clean-os8-packs | |
| 18:01 | Using Unicode arrows in the "violating rule 2" transcript to make it clear that we don't expect the user to the type comment text into the terminal. check-in: 059a06d4f5 user: tangent tags: clean-os8-packs | |
| 17:59 | Yet another tweak to the U/W FOCAL supplement's discussion of lowercase input. check-in: 20159fe6db user: tangent tags: clean-os8-packs | |

| 17:46 | Small tweak to previous check-in: 165a9dff9d user: tangent tags: clean-os8-packs | |
| 17:46 | Reworked the lowercase input examples in the U/W FOCAL supplement to use the now-working PI constant. check-in: 15af913175 user: tangent tags: clean-os8-packs | |
| 17:41 | Added fragment identifiers and named anchors to all of the headers in the U/W FOCAL manual supplement. check-in: a72ceb276a user: tangent tags: clean-os8-packs | |
| 17:37 | Expanded the section on Lowercase Input in the U/W FOCAL manual supplement to cover some surpring new findings. Incidentally, it now serves as a "Hello, world!" tutorial. check-in: d241323118 user: tangent tags: clean-os8-packs | |
| 17:01 | Better explanation of what ./configure --enable-os8-focal69 does in README.md. check-in: b72cc917cf user: tangent tags: clean-os8-packs | |
| 16:48 | Reworked the configure script --*focal* options and their corresponding mkos8 options so that FOCAL 69 is disabled by default and U/W FOCAL remains enabled by default. Also added documentation for all of this to the main README.md file. check-in: 942424a30f user: tangent tags: clean-os8-packs | |
| 16:17 | Added "Pasting Text in from a Terminal Emulator" section to the U/W FOCAL manual supplement. I could have put this in the Known Bugs section I just removed, but it belongs above the preexisting "Loading and Saving Programs" section, and it isn't a "bug" per se: the problem comes from the fact that U/W FOCAL is operating within the design limitations imposed by its development environment, which modern environments invalidate. The solution — if we ever do that — is therefore an enhancement to U/W FOCAL, not a bug fix. check-in: 9b0a771d74 user: tangent tags: clean-os8-packs | |
| 16:11 | Removed Known Bugs section from the U/W FOCAL manual supplement: checin [d6a7c6fede] fixed the last known one. check-in: 2e8482e9fa user: tangent tags: clean-os8-packs | |
| 16:11 | Added invitation to send patches to the U/W FOCAL manual supplement. This is a sideways way of preserving a named URL that would otherwise be removed in the next checkin. check-in: dd068e0950 user: tangent tags: clean-os8-packs | |
| 05:25 | Removed an unreferenced named URL left by [ee437c54a9] in the U/W FOCAL manual supplement. check-in: 2dc8ce6aea user: poetnerd tags: clean-os8-packs | |
| 05:23 | Since I fixed the PI bug, I deleted it from the table of known bugs. check-in: ee437c54a9 user: poetnerd tags: clean-os8-packs | |
| 05:04 | Fixed FOCAL installs. They were installing way too much and overran the limits of the system directory. Only 1 file is installed for U/W FOCAL: SYS:UWF16K.SV. Only a few files are installed for FOCAL69 all into RKB0: FOCAL.BN,4WORD.BN,4KVT.BN,8KVT.BN,8KNOVT.BN Personally I favor telling people just fetch these from the focal69.tu56 DECtape image. Also tested new UWF16K.SV, and it properly initializes PI. check-in: 6456a6e06d user: poetnerd tags: clean-os8-packs | |
| 04:47 | Replaced broken UWF16K.SV with one that works better. Root cause: I mis-specified the starting address when I did the SAVE action, and so UWF16K.SV was not properly initializing itself when run. check-in: d6a7c6fede user: poetnerd tags: clean-os8-packs | |

| 06:27 | Removed media/os8/os8.rk05: obsolete for a month or so now on this branch. If it's still wanted for reference, it's still visible at the tip of trunk and on the release branch. After the eventual release, you can roll back to the v20170404 tag to get it. check-in: ce85b8f355 user: tangent tags: clean-os8-packs | |

| 03:12 | Markdown cleanup pass on doc/dcp_wu.md: hard tabs replaced with spaces, indent level fixes for numbered and bulleted lists, use of indents for literal code sections instead of <code> blocks, etc. Also did a few minor prose tweaks. check-in: 2be9e5a11b user: tangent tags: clean-os8-packs | |
| 02:18 | Three DECtape images added for FOCAL Support. TODO: Tease out what kind of documentation we want to give on utilization, and decide what's going onto the packs. Recommendation: UWF16K.SV onto the packs. Everything else in docs. check-in: 1662ab9450 user: poetnerd tags: clean-os8-packs | |
| 02:11 | Beginnings of adding DCP Disassembler to the packs. Put relevant files on local.tu56, and complete first draft of the DCP documentation. Similarly to the U/W FOCAL documentation, a markdown version of an existing document DCP.WU, has been created. check-in: 8acfc443ab user: poetnerd tags: clean-os8-packs | |
| 00:26 | Diagnosed the "SIMH cont problem" in mkos8 and came up with a less traumatic way to re-enter OS/8 than rebooting the whole simulator without complicating the send/expect sequencing. check-in: bd610a4a17 user: tangent tags: clean-os8-packs | |

| 23:49 | Adds file_copyin data structure. All existing copyins get a new element that points to the file_copyin array or to None. cc8 install is now done using this method. This prepares for other copyins that are per file. Added extensive documentation of how copyins work. check-in: c14aa1561a user: poetnerd tags: clean-os8-packs | |

| 21:42 | Moved a bunch of the path handling from libexec/mkos8 into dirs.py. Along the way, made it possible to run mkos8 within the installation tree and have it update the installed RK05 images, not the ones in the development tree. check-in: 407cdb4014 user: tangent tags: clean-os8-packs | |
| 20:55 | Added lib/mkos8/__init__.py to the "make install" file set. It should have been done when we did the dirs.py stuff. check-in: 15eb96d740 user: tangent tags: clean-os8-packs | |
| 20:48 | The AUTHORS.md file still referred to tools/mkos8.in. Changed it to libexec/mkos8. check-in: bd022432a3 user: tangent tags: clean-os8-packs | |

| 20:05 | Minor cosmetic tweaks to the U/W FOCAL manual check-in: 3243002d8b user: tangent tags: clean-os8-packs | |
| 19:06 | The configure script now removes the bin/os8v3d-bin.rk05 file when the set of mkos8 options changes from one run to the next. This completes the evolution started in the prior few checkins, where only substantial changes to input files or build options causes a rebild of the OS/8 media. check-in: 2d871919e4 user: tangent tags: clean-os8-packs | |
| 19:03 | Put @ before new comments in Makefile.in to prevent them from echoing during the build. check-in: 7e263bdd1d user: tangent tags: clean-os8-packs | |
| 18:49 | Moved the @abs_top_srcdir@ and @builddir@ stuff out of libexec/mkos8.in into lib/mkos8/dirs.py.in, which exists only to hold those directory definitions. Then reworked the make dependencies so that simply regenerating the lib/mkos8/dirs.py file no longer causes a rebuild of the OS/8 media, since by far the most likely reason for this is that auto.def or some other *.in file changed. Also removed the simulator as a make dependency of the OS/8 RK05 media, since we just need it to *exist*, not to be older than the media. Instead, we check for it before rebuilding the media, and we only do that when one of the input files for building the media change, which explicitly does not include dirs.py. There's one missing step in all of this which can cause us to miss a needed rebuild, but that will be taken care of next. check-in: 9b76afeacb user: tangent tags: clean-os8-packs | |
| 17:59 | Comment fix check-in: ad33c84c4e user: tangent tags: clean-os8-packs | |
| 17:16 | Reorganized the mkos8/argparser component stuff into a subdirectory structure so that we can import the whole subtree with an "import *" call, so that the upcoming modules don't all need to be named explicitly. check-in: 73cf71943e user: tangent tags: clean-os8-packs | |
| 14:54 | Moved tools/mkos8.in to libexec and added it to "make install". It isn't easily usable from within the installation directory yet, but that is the plan. check-in: 47e196646c user: tangent tags: clean-os8-packs | |
| 14:20 | Extracted lib/mkos8/argparser.py from main() in mkos8, an ArgumentParser subclass that simplifies its interface for the main script's purposes, primarily by hiding away the process of setting up the parser. EDIT: This step also creates the mechanism for pulling other pieces of mkos8 out as separate modules. I just happened to choose to make this the first such external component. check-in: c14164b6fd user: tangent tags: clean-os8-packs | |

This is the baseline from which we will create a separate PiDP-8/I FOCAL manual matching what we actually ship. There are a few known missing items before we call this "finished": the ToC and charmap sections need to be recreated.

| 04:43 | The separate "bin" and "src" steps of mkos8 as run by make were causing the lone "bin" step's log file to be clobbered by the src step. When mkos8 is not running in -v mode, its log file is now named after the first legal action name given on the command line, giving obj/mkos8-bin.log and such. check-in: 69b961a3aa user: tangent tags: clean-os8-packs | |
| 02:34 | When we changed DSK to RKB0, we broke cc8. To fix this while keeping mkos8.in as simple as possible we: 1. Change the destination of cc8.tu56 to RKB0. 2. Add commands to copy CC0.SV, CC1.SV, CC2.SV to SYS and delete them from RKB0. 3. Add a SQUISH of RKB0 to defragment the hole made by deleting the CC .SV files. Now the C Compiler works as documented in the Wiki. check-in: 2cc9ef9463 user: poetnerd tags: clean-os8-packs | |

First, *-src.rk05 wasn't dependent upon pidp8i-sim, so in a parallel make from a clean build tree, it could call "mkos8 src" before the simulator was built, causing a build error. Second, *-src.rk05 wasn't dependent upon *-bin.rk05, so if a parallel make chose to try and build the src RK05 first, mkos8 would internally attempt to build the bin RK05 ahead of that, during which time make could launch its own build of the bin RK05, causing a build failure as both instances of mkos8 fought over the bin RK05 image file. The strict dependency chain now defined in Makefile.in means the dependency rule between these two RK05s encoded in mkos8 is now only used when you call "mkos8 src" by hand while the bin RK05 is missing. check-in: 345cad495f user: tangent tags: clean-os8-packs | |

| 07:07 | Moved media/subsys underneath media/os8, since everything in here currently requires OS/8 in one way or another. Doing so simplifies the path name building code in tools/mkos8 considerably. It also swaps out an explanation in media/subsys/README.md for why it is outside the os8 tree for an explanation of why it's in a subdirectory of that tree, a distinct improvement. check-in: 2a4f4cec29 user: tangent tags: clean-os8-packs | |

| 13:19 | Replaced the --disable-os8-lcmod configure script flag with --lowercase={auto,pass,upper} option which lets you control the OS/8 lowercase patches independently of the SIMH uppercase folding feature. Technically there are four possible alternatives, but two of them amount to the same thing (upper) so there are only three real choices. check-in: c941ce36b0 user: tangent tags: clean-os8-packs | |

| 20:13 | Includes batch job to patch OS/8 BASIC to cope with lower case. Two new files added to local.tu56: LCBAS.BI, UCBAS.BI they are similar to LCSYS.BI and UCSYS.BI but work on BASIC instead of the system area. mkos8.in now installs all 4 .BI batch scripts, and runs both LC batch scripts. check-in: d5c39d4421 user: poetnerd tags: clean-os8-packs | |
| 04:38 | Merged autosetup update in from trunk. This also removes the --with-* and --without-* aliases for --enable-* and --disable-* options due to a conflict with the way earlier autosetups handled this, so upstream backed that feature out.

| 13:51 | Renamed tools/mk-os8-rk05s.in to tools/mkos8.in. The new name is much easier to type, and we don't need the name to be descriptive: we have the file's header comments and docs to explain what it does. check-in: 2e6b7338de user: tangent tags: clean-os8-packs | |
| 13:43 | Added a call to "mk-os8-rk05s src" to the top-level Makefile from an "independency". There is a bug in the build script that prevents creation of bin/os8v3d-src.rk05, so it is temporarily disconnected from the dependency graph, but you can still say "make bin/os8v3d-src.rk05" to see the problem. (Some bug in the Expect sequence.) check-in: f435f0a472 user: tangent tags: clean-os8-packs | |
| 13:37 | The mk-os8-rk05s script now generates *.rk05 in the bin dir, not in the media/os8 dir, since the latter contains input files; we should not be mixing inputs and outputs in the same directory. Also reworked things to allow building out-of-tree, which not coincidentally shows the value of not mixing inputs and outputs. check-in: e0173f079b user: tangent tags: clean-os8-packs | |

| 12:24 | Small fix to allow tools/version to be run by Makefile when building out of tree. Also cleaned up the code a bit. check-in: c94cb7be8f user: tangent tags: trunk | |
| 11:42 | Added "-os8" to all of the configure script option names that affect the flags sent to mk-os8-rk05s. This is not just bowing to Emerson's hobgoblin: it is a realization that some of these options were ambiguous in meaning outside the OS/8 RK05 build process. For example, did the old --without-cc8 option imply that the host-side CC8 compiler would also not be built? The "-os8" bit is stripped in the option names given to mk-os8-rk05s, since "OS/8" needn't be specified at that level. check-in: 8d104bd4c8 user: tangent tags: clean-os8-packs | |
| 11:15 | Renamed --without-cc8 option to --without-os8-cc8, since it only applies to the OS/8 native CC8 compiler. When we this line of development eventually merges with the cc8-merge branch, we may want a --without-host-cc8 option or similar to make it not build the host-side CC8 compiler. The point is, they're separate things, and we have at least one use case where one is not desired while the other is: LCSYS.BI is a hindrance to some on the OS/8 side because they may be running programs that can't fold lowercase to uppercase and won't work without that folding. check-in: d5bd6bf808 user: tangent tags: clean-os8-packs | |

| 18:06 | Removed all send() delays in mk-os8-rk05s automatically inserted by pexpect. They aren't necessary. Only the OS/8 delays we've manually inserted are necessary.

| 12:09 | Added "pip install pexpect" stuff to the "bosi init" step, so the "make install" step following it does not fail due to lack of pexpect in the mk-os8-rk05s step. check-in: 37735a593a user: tangent tags: clean-os8-packs | |
| 12:00 | Increased the simulated terminal speed implied by the new os8_kbd_delay function in mk-os8-rk05s from the 110 bps of an ASR-33 to the 2400 bps of the more-nearly contemporaneous VT05. Since this does not actually save any build time on my machine — presumably because other I/O overheads swamp it, such as the simulated TU56 reading time — I also removed all the comments about the possibility of going even faster. We've squeezed all the juice out of this stone we can. check-in: 354fa7230b user: tangent tags: clean-os8-packs | |
| 11:42 | Decreased the "sleep(0.5)" stuff in mk-os8-rk05s to a smaller constant (0.0909...) based on the data rate of an ASR-33 teletype which must be the worst-case value for keyboard input to OS/8. Testing shows this gives identical binary media to what the old constant produced. This is backed up by diffing the mk-os8-rk05s.log file produced by the two versions of this script, which differ semi-randomly in the instruction being executed by SIMH whenever it gets one of the Ctrl-E commands. This change saves about 12 seconds from a 55 second build on my machine relative to the old 2 cps behavior! check-in: 6b8ea89df4 user: tangent tags: clean-os8-packs | |

| 11:46 | Added --without-* options to the configure script corresponding to the other *.tu56 files in the media/subsys directory, which pass similarly named options to the mk-os8-rk05s script. These all default to "off", meaning that these components are normally installed. (Technically, that's backwards: autosetup considers them boolean enabled by default options, which causes the --help message to document them as --disable-*, since that is the only form of option that causes a change in the default behavior of the configure script. You can say things like ./configure --with-cc8; it just doesn't do anything useful.) check-in: 5fcb62ab70 user: tangent tags: clean-os8-packs | |
| 11:09 | Added the "./configure --with-music" option, which in turn causes the flag of the same name to be passed to the mk-os8-media script when called from the top-level Makefile. check-in: 23021c2cc5 user: tangent tags: clean-os8-packs | |
| 11:04 | The mk-os8-rk05s script now runs as part of the normal build process as well as a prerequisite for the "install" and "run" targets.

The new one is still not finished, but it will be by the time this branch is marged into the trunk, and it's convenient to be able to say "make run" to test our progress. check-in: 9df3792722 user: tangent tags: clean-os8-packs | |
| 10:31 | Added --with-music option to tools/mk-os8-rk05s script. This checkin also changes pretty much every bit of code that referred to the media/os8 subdirectory, since we now need to refer also to media/subsys.

| 09:39 | The new mk-os8-rk05s -v flag now has an effect, causing SIMH and OS/8 output to go to the console instead of to a log file, which is now called obj/mk-os8-rk05s.log instead of log.txt at the top level. This option also suppresses most of the progress messages we added recently since the output from SIMH and/or OS/8 suffice in that case, and we don't want their outputs polluted by messages from the script in that case anyway. check-in: 66481ebd58 user: tangent tags: clean-os8-packs | |
| 09:20 | Replaced the command line parser of mk-os8-rk05s with an ArgumentParser based one, which does better error checking and generates a nice usage message.

| 01:45 | Changed a bunch of "return;" lines in the CC8 cross-compiler to "return 0". It's using K&R function declarations, which means you get an implicit "int" return type, and Clang won't let you just "return" in this case. check-in: b74fa40bf2 user: tangent tags: cc8-merge | |
| 01:43 | Changed the declaration of main's argv parameter for the cross-compiler from int* to char** to quiet Clang. This does mean the compiler can't be bootstrapped on OS/8 by CC8 from these sources, but according to Ian Schofield, that produces an unusably big assembly output already. Therefore, the only important compiler for this file is GCC or Clang. check-in: c5afc7544f user: tangent tags: cc8-merge | |

| 01:13 | Merged in the 2017.07.08 distribution of Ian Schofield's Small-C based CC8 native and cross-compilers for the C programming language. This checkin differs in many ways from the upstream distribution so far, with more changes planned before merge into the trunk: * Converted the RTF and the Readme.txt files to Makrdown format. * Fixed some typos and grammar errors in those files flagged by LibreOffice Write. * Changed "PDP/8" to "PDP-8" and similar, to match DEC conventions. * Fixed some case inconsistencies: e.g. "N8.c", which is actually distributed as "n8.c". * Replaced the link to Vince Slyngstad's SVN checkout image to a link to the HTML page that describes it. * Moved the top-level RTF doc's Addendum up above the Conclusion as the new Preprocessor section. * Changed "hosted" to "cross" in the top-level doc, that being the more common term for this sort of C compiler, and because "hosted" has a different meaning in the C standard. * Renamed the SMC directory to "cross" for the same reason; also, this can't really be said to be a distribution of Small-C any more, with so many differences. * Qualified "native" with "OS/8" or "PDP-8", as seemed appropriate. The unqualified form could refer to the cross-compiler, since it is native to the SIMH host! * Renamed the "ccos8" subdirectory to just "os8", since this software is under a cc8 directory in the PiDP-8/I tree, with subdirectories for the CC8 cross-compiler (cc8/cross) and the CC8 OS/8 compiler (cc8/os8). * The top-level PiDP-8/I build system now builds the cross-compiler, so I removed all the other Makefiles and project files. * Moved the warning about using unix2dos into the top-level README.md, from cc8/smc/test/Readme.txt, where few would notice it. * Consolidated redundant copies of OS8.TM and libc.h into a cc8/include directory, with symlinks checked in for the benefit of the native OS/8 compiler, which would make use of relative paths annoying. (When checked out on a Windows box, the symlinks will give copies of the files, due to severe limitations in the NTFS symlink implementation.) I also renamed OS8.TM to init.pa, as this doesn't seem OS/8-specific, and it appears to be PAL assembly code, not a temporary file, that being the normal meaning of *.TM on OS/8. * Left out *.s, as they are generated files. (I did check in header.sb, as it appears hand-written.) * Renamed 7.script to boot/cc8.script and rk05.dsk to media/os8/cc8.rk05, and updated the references. * Removed the VC8 stuff from the boot script, since the current SIMH build does not include that, so it generates errors on start. check-in: 6cfe232a65 user: tangent tags: cc8-merge | |

| 12:39 | Disabling PDP-8 CPU idling when ILS is enabled. This has always been the default for some boot/*.script files, but we need to enforce it when ILS is enabled because we need regular CPU instruction rates to make this work. Closes [c9eb5ac0144] Also added a new configure script flag, --no-idle, to allow NLS users to disable CPU idling too, if they like. The *.script files generated from *.pal are marked noidle, with no way to change it at present.

| 11:46 | The new PDF size change detector in the simh-update script would cause an error if the output PDF file didn't already exist. This doesn't happen here in practice at the moment, but it could happen later, either because of a "fossil clean", a new Fossil checkout, or because we've added a new DOC -> PDF conversion. check-in: d3e46c3944 user: tangent tags: trunk | |
| 11:43 | Another SIMH update pass. Mostly more Coverity stuff. check-in: a351a7bfa1 user: tangent tags: trunk | |
| 11:39 | The use of cmp(1) in tools/simh-update to detect PDF change wasn't doing the right thing, apparently because metadata is changing on each re-render. (e.g. timestamps, possibly GUIDs, etc.) Switched to a simple file size difference test, which should suffice for our purposes. Potentially a substantial change could slip through this way, but we'll eventually catch up if that ever does happen, since eventually some size difference will occur. check-in: 774a08c6aa user: tangent tags: trunk | |
| 11:22 | Optimized the SIMH MS Word -> PDF doc conversion part of simh-update a bit: it now replaces the versions in the public unversioned file set only if the new files compare differently. check-in: f5978c5732 user: tangent tags: trunk | |
| 10:36 | Changed tools/version to use 10 hex digits for the Fossil checkin ID part to match the Fossil timeline default length, to avoid confusion when telling people to match the value given here to the value on the timeline page. Not everyone will understand that 8 hex digits is more than enough to make a unique match in our small-ish repository. Also made the build depend on tools/version such that when that script file changes, it does a rebuild in case some future change like this occurs. It wasn't necessary this time because we also touched Makefile.in, but we might not always do so in the future. check-in: b68d4a68fc user: tangent tags: trunk | |

| 03:43 | The code matching USB-attached files to PDP-8 device name extensions wasn't checking that the extension is at the end of the file, so a file called a.pt.b would match the *.pt check. It also wasn't ignoring dotfiles, so not only would it waste a bunch of time looking at . and .., it would have mounted .foo.pt, which probably isn't what you want. Also added a bunch more debugging. check-in: fe9dec9077 user: tangent tags: trunk | |

It was previously set for an RL01 drive attached to an RL8A disk controller for the PDP-8/a, which is about 8 years after the PDP-8/I, and the drives themselves are more commonly associated with PDP-11s besides.

| 08:01 | Initial work towards fixing [88fad950a3] by adding an interlock between the new start_pidp8i_gpio_thread() wrapper and the early init stuff in gpio_thread(). Basically, instead of calling sleep(2) after creating the GPIO thread to give that thread time to start up, we play a little game with mutexes that will block the main thread if the GPIO thread isn't sufficiently initted by the time we're ready to return from our start_pidp8i_gpio_thread() call. Untested, since the work is being done on the desktop, and it only takes effect on the Pi. check-in: 1e40f7741f user: tangent tags: interlocked-gpio-start | |

| 04:43 | The attempt to do read-only I/O on the Raspberry Pi GPIO peripheral from the scanswitch program on the basis that we only need read-only access here falls down in reality because merely reading one of the GPIO pins fails with a segfault if you don't have the peripheral read-write mapped. This can only be classed as a bug in the GPIO peripheral driver, but we have to work with the software as we find it. check-in: 535a9561c2 user: tangent tags: trunk | |
| 04:22 | The two GPIO thread start cases in pidp8i-sim and pidp8i-test weren't equivalent, so the prior checkin prevented the simulator from starting on non-Pi hosts. The difference is that pidp8i-test *must* map the GPIO periphieral into RAM to proceed, while pidp8i-sim would like to have it mapped, but it can fall back to stock SIMH behavior if it isn't present. Therefore, added a new flag to start_pidp8i_gpio_thread() to indicate whether the GPIO peripheral must map or not. Also made a similar distinction for map_peripheral(), which now understands non-exclusive mappings for use by libexec/scanswitch while another PiDP-8/I based program runs: there's no reason we can't get the switch values in this case, we just need to open the peripheral for read-only access, without locking it. Also fixed a bug introduced in [0bd33744ffb07b75]: the @VERSION@ string in the config line was accidentally replaced by its value at that time, doubtless due to hasty copy-pasting between gpio-common.c and gpio-common.c.in. check-in: d5722b7ca4 user: tangent tags: trunk | |
| 02:49 | scanswitch must now link with -pthread on Linux since it linkes to gpio-common.o, which how includes the new GPIO thread start/stop routines, even though it doesn't call them. check-in: ee85a40171 user: tangent tags: trunk | |
| 02:42 | Moved the start/stop GPIO thread code common to both the pidp8i-sim and pidp8i-test cases into a pair of helper routines in src/gpio-common.c.in now called by both. gpio_thread() is now module-scoped, since other modules now no longer need to know about it. check-in: 498ea766b0 user: tangent tags: trunk | |
| 01:45 | The recent renaming of the top-level "os8test" target in the Makefile.in wasn't reflected into tools/simh-update.in, so the OS/8 test after a successful simh-update run wasn't running. check-in: 160dff50d7 user: tangent tags: trunk | |
| 01:43 | Cleaned up GPIO thread starting and stopping code at the top of main() in src/scp.c: match local style, give less generic error message on thread start failure, and use variable names less likely to conflict with future upstream SIMH changes. check-in: b0534785eb user: tangent tags: trunk | |
| 01:34 | Removed "Ian Schofield" from src/PDP8/pdp8_cpu.c license comment, since his brtval update patch has since been removed from this module. The closest rough equivalent to this is now in src/gpio-ils.c. check-in: 36f36410b9 user: tangent tags: trunk | |
| 01:30 | Merged in PDP-8 DECtape fixes from SIMH upstream check-in: 7b8b53d287 user: tangent tags: trunk | |
| 01:27 | Removed the negative enum value test in the prior checkins because it causes clang on macOS to complain that this can't happen. It's right, if everyone is playing ball, but since we have the assert test on unhandled cases, we don't need to squish the warning. We'll just catch it at run time via the assert() path rather than by an explicit test. check-in: 7f98b5a844 user: tangent tags: trunk | |
| 01:21 | The prior checkin removed the last legitimate reason for src/scp.c to be generated by autosetup from scp.c.in: it needed the @BOOTSCRIPT@ value to build the "do $bootscript" commands. We now delegate that back to the pidp8i.c module which has a better reason to be generated from pidp8i.c.in by autosetup. check-in: ce2c9d0444 user: tangent tags: trunk | |
| 01:17 | Moved all handling of awfulHackFlag into the pidp8i.c module and cleaned its handling up so that it is no longer "awful". It is now just a module global set during the brief window between when the switch handler sets it from within the PDP-8 CPU core and when SCP calls back into this module via a new pidp8i.h API that builds the command we want SCP to run for us as part of handling that front panel switch combo. For the most part, this is functionally identical to the previous implementation, except for being a lot cleaner. There are some messaging differences, and we now exhaustively handle all of the command value cases, however. check-in: 491698e049 user: tangent tags: trunk | |

| 23:33 | Reworked the "awful hack flag" handler in src/scp.c.in to a) eliminate the code duplication with respect to the upstream version; b) match the upstream style; c) clarify the code flow; d) add several comments and one diagnostic message. No functional change. check-in: 67498625df user: tangent tags: trunk | |
| 22:56 | Rather than ifdef'ing out all the uses of the upstream sim_video module and not including it, we now build it without defining `SIM_VIDEO`, which basically turns it into a stub module that compiles quickly even on a Pi 1. We don't use it presently, but we may need it later for things like on-Pi Spacewar builds where the X-Y vector output uses the SIMH SDL video subsystem. The primary point of this change, however, is to let us remove unnecessary changes in the patch we make relative to the upstream SIMH code. check-in: a328b94dcb user: tangent tags: trunk | |

| 06:24 | The DEP switch handler wasn't ensuring that *pPC is limited to 12 bits, even though the LOAD_ADD handler did ensure it. Somehow, between these two points, PC is getting its high bits set, which causes us to deposit the SR into the wrong core memory location.

Now that we're using 2G cards, we can just copy the slack space, too, and expect it to compact down nicely in the Zip step. This in turn let us get rid of the clumsy "image-nls" tag scheme, since we can just use the parameter space vacated by the vague "object" parameter. Since we've got a single-core Pi here to build images with, we don't need to pass --no-lamp-simulator to the "bosi init" step, either, the other user of the "object" parameter.

| 14:13 | The bosi image step now zeroes the SD card prior to re-writing the image to it.

| 11:38 | Fixed up some unnecessary differences between our fork of SIMH's PDP-8 simulator and the upstream Git version we most recently sync'd with. The only functional difference is that our version would ignore SIMH breakpoints. I can't see why we'd want that: if someone sets a SIMH breakpoint, of *course* it should drop into the sim> prompt, even if this isn't period-correct. The user started the anachronistic behavior by setting the breakpoint. check-in: 5bf7e2f748 user: tangent tags: trunk | |

| 16:13 | Moved the "skip early" stuff at the top of set_pidp8i_leds() out into the PDP-8 simulator CPU main loop, which calls that function. Testing shows that this function call costs ~1.0 MIPS all by itself! check-in: 29dd841b8d user: tangent tags: led-counters | |
| 14:58 | First cut at abstracting the simple "update panel LEDs" loop for use by NLS full time and ILS while the processor is in STOP mode. The display structure now contains current-state bitfields like the traditional ledstate[] values, which this new combined routine uses. check-in: e75894b4ec user: tangent tags: led-counters | |

| 10:45 | Restored the dynamic "leave early" mechanism at the top of set_pidp8i_leds(). This restores ~8 MIPS operation on my Pi 3, and I think we can get away with it now that we're calculating LED brightness based on an aggregate history. This checkin greatly decimates that value, but before, we were doing single- instruction sampling. We may have to adjust the decimation value, but even a bit of decimation should help a lot. check-in: 5940370e0c user: tangent tags: led-counters | |

| 08:52 | I've convinced myself that the only place we need an atomic operation in the new "struct display" mechanism is in the pointer swap, so replaced the rest of the uses of __atomic*() with simple C code, and explained the reason it can be that way in extensive comments. check-in: af7a539f6a user: tangent tags: led-counters | |

| 06:26 | Fixed a race condition in the switchstatus[] setup sequence, where a slow-to-start blink_core() implementation wouldn't read in the switch values early enough, leaving the array set to all-zeroes, which means "all switches closed," which the simulator sees as including SING_INST + SING_STEP + STOP == shutdown! Also dropped one indent level in blink() by returning early from the function when the GPIO memory mapping doesn't happen instead of skipping the bulk of it by wrapping it in an if block. check-in: a36dc13209 user: tangent tags: trunk | |

| 12:39 | First attempt at taking the simple bitfields used for communicating register values between the PDP-8 CPU instruction execution loop and the PiDP-8/I front panel GPIO thread and switching them to a 2D array of LED "on" counts, allowing us to accuractely calculate the brightness of the LED at that time. This code builds on macOS, but it has yet to be tested on the Pi, which is part of why this is being checked in on a branch. The other reason is that we're pretty sure it's going to take at least one more checkin to turn this into something we can ship. check-in: 66a2818a47 user: tangent tags: led-counters | |

| 09:53 | Reworked the set_pidp8i_leds() calls so that there are now only two of them, one at init time outside the CPU dispatch loop, and once down at the very end before we fetch the next instruction. The manipulation of the pause, execute, and fetch LEDs now happens via separate dedicated functions, so we're not flashing the whole panel several times per PDP-8 instruction. check-in: c342062fc7 user: tangent tags: set-leds-cleanup | |
| 09:37 | Moved NCOLS, NROWS, and NLEDROWS constants out of gpio-common.c.in into its header file so we don't need to export the corresponding integers. This has the nice side benefit that we can now use these values in places where C only allows constant expressions, getting rid of the recently-added malloc() for the temp copy of the LED values. check-in: aaad3f7b35 user: tangent tags: set-leds-cleanup | |

| 02:09 | Several adjustments to set_pidp8i_leds() calls. The main practical improvement is that we can now see execute state on the front panel. It was in that state too briefly before it got reset to fetch. check-in: 3c2086101e user: tangent tags: trunk | |
| 01:44 | Removed the code that skips updating the global ledstatus[] values from the PDP-8 CPU core based on the human PoV limit. Because the GPIO thread runs asynchronously with it and has its own timing, these two high-jitter timing loops created a messy beat frequency on the front panel, which you could see in a tight KSF ; JMP .-1 loop, as OS/8 does when idle, waiting for a key. This mechanism came to us in the merger of the common parts of ILS and NLS, and ILS only needed it when it was modifying the LED brightness values values in the SIMH thread instead of in the GPIO thread as it does now. The only argument for continuing to do this — and for also doing it for NLS — is that it avoids a bunch of recalculation that the human couldn't see, but that is only true if the GPIO thread is able to stochastically sample the LED states so that even with the asynchronous jitter going on, a tight loop like the above eventually blurs together to a nice 50/50 mix of the two instructions' LED states, especially under the ILS. Ultimately, any attention paid to the human PoV limit has to be over in the GPIO thread. check-in: 61ce7d6852 user: tangent tags: trunk | |

| 11:28 | Added redirecting Makefiles to the examples, src, and src/PDP8 subdirectories so that those who like to work on source code from within those trees can "make" from there, too. These Makefiles purposely redirect only top level "build the software" type targets, leaving out "run the system" or "install the system" type targets, which must be run from the top level. These intermediate Makefiles also don't try to do anything special for individual targets. So, there is no way to rebuild, say, a single example from the examples subdirectory. This is not a recursive make system, where the top level delegates to the subdirectories, on purpose.

| 02:17 | Merged int-math-ils branch back in even though the stated purpose of the branch was a failure, since the new code does at least move knowledge of brtval out of the pidp8i.c module and into gpio-ils.c, so that all ILS code is now in that one module. check-in: 5c46b0cc5e user: tangent tags: trunk | |
| 02:15 | Returned brightness math to FP, as the integer approximation had only a few percent CPU improvement by top(1)'s measure, not enough to pay for the increased difficulty of understanding. Closed-Leaf check-in: 2015c958b0 user: tangent tags: int-math-ils | |
| 01:49 | Experimental try for integer math approximation in the ILS feature. This also merges the brightness value calculation into gpio-ils.c and removes the ILS-specific call rate code in set_pidp8i_leds(), since I realized that the required update rate was simply to make the call rate equal the iteration rate of blink_core() over in the GPIO module! That is, we were trying to synchronize two functions in two threads, even though they had no reason to communicate. This change also effectively returns the ILS module to receiving ledstatus[] as its LED value input, rather than brtval. This should mean we can link pidp8i-test and Deeper Thought 2 against the ILS module, once we've proven out the feature. check-in: 87e9a944ef user: tangent tags: int-math-ils | |
| 00:03 | set_pidp8i_leds() now flashes the new LED values over in a single memcpy() call instead of setting one row at a time over the course of the bulk of the function in case this makes the display a bit more consistent.

| 22:12 | Updating our estimate of the proper skip count in set_pidp8i_leds() in order to give an LED value update rate of ~100 updates per second, roughly equal to the human PoV limit. The prior method used a hardcoded value which means on really fast Pis we're updating more often than we need to, and when the PDP-8 simulator is throttled down (such as for a blinkenlights demo) we were updating way too slowly. As proof of concept, the ac-mq-blinker example now runs at less than 1/10 the speed it used to, yet it looks vastly better than before. Closes [28d33e9046]. check-in: 1da4ee0590 user: tangent tags: trunk | |
| 19:47 | tools/mkbootscript was attempting to sort the core addresses in its boot/*.script outputs, but it was using the default sort ordering, which in Perl happens to be string ordering, not numeric ordering as we were blindly assuming, and that gives odd results with some scripts. Fixed. check-in: 3c3643f325 user: tangent tags: trunk | |

The only way to get the incandescent lamp simulator is to not give that configure option and to run it on a multi-core host. check-in: 2884daa90c user: tangent tags: trunk | |
| 17:34 | The recent refactoring of the GPIO module allows us to replace the current no-lamp-simulator and nls-test branch system with a configure script option, --no-lamp-simulator. It simply selects whether gpio-nls.o or gpio-ils.o is linked into pidp8i-sim. With this change, we've added either an [ils] or [nls] tag to the configuration string emitted by the GPIO module. Closes [e06f8ae936]. check-in: f85aed2fc3 user: tangent tags: trunk | |
| 17:12 | Restored the prior printfs() and such from the top of blink() as a new single-line version and configuration message modeled on Erlang's emulator info statement. check-in: 8f068cd978 user: tangent tags: trunk | |
| 17:09 | Extracted the elements common to both gpio.c and gpio-nls.c as gpio-common.c and renamed what's left of gpio.c to gpio-ils.c. The gpio-common.c module does all the common elements, then calls into blink_core(), now implemented twice in gpio-[in]ls.c, only one of which is linked into any given program. check-in: 1769197e50 user: tangent tags: trunk | |
| 02:25 | Merged the diffs between v20170116 and the tip-of-trunk into the no-lamp-simulator branch, changing some of it to fit with the intent of that branch, then checked it into this new nls-test branch because we're not yet ready to bag and tag the next release. This branch might not be temporary. We might need to do one of these partial merges prior to a release again later. Now we'll have a place to do it.

| 18:45 | If INSTUSR is "root" during the configure step (say, because you've run it as "sudo ./configure") it will now error out rather than generate init scripts and such that we know are wrong. This can happen by accident, such as whenever you touch a *.in file that causes an autoreconfig; if done while sudo'd for some reason, you get this effect. This is fixing a real occurence, not a purely theoretical problem. check-in: 1f7c6b2d7b user: tangent tags: trunk | |
| 18:39 | When you give ./configure --debug-mode, it skips the checks for the -f optimization flags to the compiler. check-in: 4b728a7da2 user: tangent tags: trunk | |
| 17:46 | make now reconfigures and rebuilds when any of the files produced from *.in are removed. Previously, only a change to *.in would cause this. This checkin also does a better job of removing such files on "make clean", so that "make clean && mmake" does a complete rebuild without getting stuck, requiring a manual ./configure. check-in: 008c4881a6 user: tangent tags: trunk | |
| 15:52 | Fixed a couple of problems in the way SING INST and CONT were handled. These are related because in the old way of doing things, these two switches had a kind of lock-step operation that tried to split instruction execution over two separate passes of the PDP-8 sim's CPU instruction decoding loop. Now these two switches are handled more or less the same way as all the others, in a single cycle of the instruction loop. With the prior scheme, while the processor was stopped with a HLT instruction, pressing CONT would basically jump 2 instructions forward, rather than continue to the instruction after the HLT, skipping it. This fix closes [f961906a5c]. While in there and reading the DEC documentation describing the proper operation of the switches, I found that we weren't handling SING_INST properly at all. When flipped with the processor in free-running mode, it is supposed to stop the processor just as if you'd pressed STOP. Now it does. (I could have checked this in separately, but the two fixes are in overlapping and interrelated sections of code, so it doesn't make sense to check in a purposely-written erroneous SING INST handler just to get a separate checkin comment.) check-in: 9a12773270 user: tangent tags: trunk | |
| 14:13 | Un-microcoded the RAL HLT instruction in examples/bit-rotate.pal: it tickles a palbart bug, because these are group 1 and group 2 OPR instructions, respectively! Consequently, the SIMH PDP-8 assembler sees only the HLT and doesn't do the RAL. check-in: 193d34204c user: tangent tags: trunk | |

| 06:15 | Removed src/gpio-nls.h in the no-lamp-simulator branch for the same reason we removed it from the trunk branch. Closed-Leaf check-in: 8c80abac2e user: tangent tags: nls-next | |
| 06:14 | Removed src/gpio-nls.h: the differences between the two versions of the GPIO module are all in the *.c files. No point shipping two identical *.h files, especially given that no other *.c file has ever #included gpio-nls.h. check-in: a22a47a8fa user: tangent tags: trunk | |
| 06:03 | Similar comment fix for src/gpio-nls.c as was just done on the no-lamp-simulator branch. check-in: 63858bf03c user: tangent tags: trunk | |
| 06:00 | During the v20170116 release process, I just copied the no-lamp-simulator version of gpio.c over the top of gpio-nls.c, which is more or less fine, but it means the header comments still refer to gpio.c, not gpio-nls.c. Fixed the comment. check-in: 4969e1650f user: tangent tags: nls-next | |
| 05:56 | The check for brtval in src/PDP8/pdp8_cpu.c.in became obsolete when we extracted the bulk of the front panel interaction code to the new pidp8i.c.in module. Rather than change the test to look in that new file, changed it to look in src/gpio.c, which is shorter and accomplishes the same goal. check-in: d2dd4232ce user: tangent tags: trunk | |

| 13:53 | The pidp8i.c.in file in the prior checkin was missing changes mistakenly made to the generated pidp8i.c file. Reapplied them to the source file. check-in: f261173b93 user: tangent tags: cpu-cleanup | |
| 13:28 | Factored the vast bulk of the PiDP-8/I specific code out of PDP8/pdp8_cpu.c into a set of several new functions defined in a new PDP8/pidp8i.c module. Along the way, reworked the code style to match the rest of SIMH. Very little is functionally different, and the differences are intended to only be spot improvements not needing a separate checkin comment. Examples: a) some of the bit twiddling math was overly complex, so reduced several 3-ish line calculations to one-liners; b) appended strerror(errno) to some error message strings; c) reorganized the switch testing code a bit to reduce the number of times certain tests and calculations are made. This change also greatly reduces the number of PiDP-8/I specific globals. All but one of the app-wide globals that used to be defined in pdp8_cpu.c.in are now scoped to the pidp8i.c module, and all but one of those are statics scoped to a single function in that module. Because this refactoring moves the @BOOTDIR@ usage from pdp8_cpu.c to the new pidp8i module, the SIMH module is back to being a static C file, while pdp8i.c is generated from pidp8i.c.in. Also added a whole bunch more comments, and moved some prior comments into bug tickets. Checking this in as a branch because it is so extensive that I might have broken something. It hasn't been tested yet because I did the work on my fast desktop PC, not on the Pi, there being no point since the changes are so wide-reaching that it didn't even start building again until just before this checkin. Now it's time to do that testing. check-in: 642a7201a0 user: tangent tags: cpu-cleanup | |

| 04:58 | The usermod command in bosi's reset routine only worked correctly on the first pass, since the user was still called "pi". If run again on a later pass where that user is now called pipd8i, it now only does the password change. check-in: 34d25dce5b user: tangent tags: trunk | |

| 04:48 | Ported difference minimization between src/gpio* modules from the no-lamp-simulator branch where the only difference between these files is a comment to the trunk branch where the differences are more substantial, but where the needless diffs should still be removed. check-in: ec5fd1c92c user: tangent tags: trunk | |
