| | ====== April/May work ====== |
| | |
| | **2026-05-03** |
| | |
| | |
| | ===== lDOS kernel ===== |
| | |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/5ff9ade920ad|Replace entries in the int 21h DISPATCH table for user stack functions]] (33h, 50h, 51h, 62h, 64h) by servernoop which acts like a DOS v1 style error (AL = 00h, CF unchanged). This avoids the inevitable crash if one of these functions is called from a server call (int 21h function 5D00h). |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/1726146996d4|Rename implementations of functions 25h and 35h]] to indicate they're for server calls. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/8b275773dc26|Handle non-server calls for functions 25h and 35h early in the int 21h handler]], without using any DOS-internal stacks. |
| | * [[https://hg.pushbx.org/ecm/msdos4/rev/98356c0f2cfc|Detect out of range AH function]] in server call (function 5D00h). |
| | |
| | |
| | ===== IntList ===== |
| | |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/2b441c3c982a|Allow matching multiplefiles in dofindfile]] |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/f0433d31482e|Fix perl foreach loop resetting the index variable]] after it ends, and use summarymatched variable as the found index. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/2e8bff99334d|Pass array reference to enterresultfile]] allowing to pass multiple files per call. |
| | * Optimise [[https://hg.pushbx.org/ecm/intlist/rev/4821f4c35e19|to stop the dofindfile loop once all entries are found]]. |
| | * Add a Path::Iterator::Rule rule [[https://hg.pushbx.org/ecm/intlist/rev/95ba322cf455|to match only pathnames]] matching "/INT xx" for INTERRUP.LST entries, detected from the unique ID starting with two hexits. Contains a reference to [[https://perlmonks.org/?node_id=11167638|a perlmonks.org question]] in which I didn't notice a typo (dash instead of equals sign) until after I was told my example couldn't generate the errors that I reported. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/0d578e59030f|Extract function generaterule]]. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/4b0fb0e88886|Find files in two passes]], first with filename ID match. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/56c60f376eeb|Allow calling dobeep without curses]] set up yet. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/f936e32fadb9|Beep if second find file pass ran]]. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/e517ffb5a4dd|Switch to Path::Iterator::Rule iter_fast]] over iter. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/76d86545d085|Combine the not name and name rule]] into one rule. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/5f89ad3a0e9c|Add a timer]] to display how long a capital-P L command takes. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/cddeffb62ca6|Add code to call enterresultfile repeatedly]], commented out. |
| | * [[https://hg.pushbx.org/ecm/intlist/rev/2a4a01038dc9|Use the getpriorstate and setnewstate functions to fix the status page]] init and exit. This probably duplicates some work but it doesn't cost much performance. |
| | |
| | |
| | ===== SRDISK ===== |
| | |
| | * doc: [[https://hg.pushbx.org/ecm/srdisk/rev/be9a6cc641f2|Fix a few typos]]. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/82f740870bfd|Add most header dependencies]] to makefile. Includes a scriptlet in the changeset message. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/a75bc9c9bec6|Add some remaining header dependencies]]. Again includes a scriptlet. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/6349b8b8b5d4|Don't generate .s files during compilation]] of .c files. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/65c2d604ccdb|Use ia16-elf-objdump]] |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/ddd643084b03|Generate gas listings with -g switch]] (using [[https://codeberg.org/tkchia/gcc-ia16/issues/8|the updated gcc-ia16 toolchain]]). |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/a4f337918ae1|Implement a naive /RESERVE: switch]]. May not work as intended when the RAM disk already contains any data. |
| | * [[https://github.com/LoopZ/TheList/blob/db3d76cb/source/Interrupt%20List/INT%202F%20Multiplex/Memory/INT%202F4310%20EXTENDED%20MEMORY%20SPECIFICATION%20XMS%20v2%20GET%20DRIVER%20ADDRESS.txt#L110|As suggested]] by the interrupt list, [[https://hg.pushbx.org/ecm/srdisk/rev/b02d0c3f7bdf|pass BL = 00h to XMS functions 8 and 88h]]. This required adding an lframe variable for the XMS entrypoint in three spots, as these addressed the entrypoint using DS:BX. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/35799fca15c4|Fix build with srdiskc.exe >= 64 KiB in size]]. WarpLink doesn't like a single section stretching over more than 64 KiB. It doesn't have a problem with two sections adding up to more than 64 KiB though. So split the configuration program payload into two sub-payloads: One for the first 40 KiB and one for the remaining part. This assumes that srdiskc.exe is at least 40 KiB and no larger than 104 KiB. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/1b4a30077c60|Implement /RESERVE: option with /MAXSIZE]], allocate as much as allowed while honouring the reserved memory. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/25587964283e|If /FREEMEM: and /RESERVE: are both used, treat a size of zero as an error]]. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/6432eea02be5|Add /LETTER switch]]. Will return an errorlevel between 32 and 63 if it would have been zero, corresponding to the drive being operated on. |
| | * [[https://hg.pushbx.org/ecm/srdisk/rev/8cd55465707f|Accept a drive specification starting with 0]], at least one more digit, and a colon. With the number N, this selects the drive that is found by skipping the first N SRDISK drives. This allows selecting different drives without knowing the drive letters already. |
