Open-source dos.library

[Don_Adan]

New version of dos.library is available.
Checked all BCPL routines, written in ASM, some bytes gained.
Added original comments (plus a few mine) for these routines.
Some comments can be outdated, due changes/optimisations.
For hunting for possible bugs the best is test this version with
programs written in BCPL, mostly (only?) old Amiga programs like parts
of WB 1.3.

[Don_Adan]

New version of dos.library is available for tests.
Optimised LVORequester.
Added more original comments to the source code.
Updated LVOReadArgs related routines to v42.1, mostly less stack usage.
Updated LVOSetVBuf routine to v42.1.
* /* if size is -1 and buff is NULL only change mode */
* // if fh_Type (port) is NULL then this is a NIL: filehandle, so
* // silently ignore the call (success). If we let this go through,
* // it will set Func3, and actend will be called, and it will try
* // to send a packet to NULL (very bad).
Bumped dos.library version to v42.2.

In cosmo's optimised dos.library he did :
- removed all 68000/010 support
- removed some unused code
- many absolute address turned relative
- set stack to 4000 for PRT, PAR, SER, RAW, CON & RAM (SetPatch v44.38)
- R_Cli optimized a bit
- R_CurrentDir optimized a bit
- R_Input optimized a bit
- R_IoErr optimized a bit
- R_Output optimized a bit
- R_GetArgStr optimized a bit
- R_GetConsoleTask optimized a bit
- R_GetFileSysTask optimized a bit
- R_GetProgramDir optimized a bit
- R_SelectInput optimized a bit
- R_SelectOutput optimized a bit
- R_SetArgStr optimized a bit
- R_SetConsoleTask optimized a bit
- R_SetFileSysTask optimized a bit
- R_SetIoErr optimized a bit
- R_SetProgramDir optimized a bit
- 120 bytes saved


maybe you can do it also, since he abandoned his work

Your newest dos.library is running well Don_Adan!

[bladecgn]

The latest version as well as previous ones don't work for me unfortunately.

If I copy the entrire prefs folder to ramdisk an then try to duplicate it using the workbench menu the system freezes unfortunately.

[HanSolo]

Don_adan can you look at this ? I am using directory opus magellan so I missed this bug.I confirm that bug is real.

[pawelek]

Yes, is a bug in dos.library 42.2 (DonAdan), new bugfix version soon.

Thanks for tests. Fixed version is available on the WT page.

Perfect timing, burning into some freshly erased eproms right now.

[bladecgn]

I can confirm the duplicate prefs folder in ramdisk is fixed.

Thank you Don Adan!

I just received the following bug report:

"When installing some older software like FinalCalc and AdPro, I have a dos issue that says that cannot find file on like the next disk inserted. That is, I go through the installer and once it asks for next disk, I insert it. Workbench sees it and is shown in the shell as well but for some reason dos can't find the file on next disk. Then the script aborts with a DOS error.

If I do not do the dos.library loadmodule in startup-sequence and revert back to older one all is okay. Also, when I copy disk2 to RAD: instead it is okay."

@Don_adan

Is segTracker patch useless witch your dos.library or not ??? Meybe you could implement it if yes. Could you post list which patches are useless with your libraries.

Sorry for resurrecting the thread. But how do we make this work with different localee catalog files?

[Don_Adan]

Even if this is fast/optimised/a few fixed version of dos library, then has a few (minimum 2) my bugs, included locale bug, i think. If I will be back to life, then maybe I will try to find and fix bugs. Perhaps with WinUAE debugger it can be easy enough to find bugs, but I dont used WinUAE. But sources are available, everyone can try.
