2004 May 30 - Build 2035
|
||||
-------- Bart Oldeman (bart@dosemu.org)
|
||||
+ Changes Lucho + Tom
|
||||
* config.c, fatfs.c, globals.h, init-mod.h: From Tom: must
|
||||
set r_bpfat for C_BLDBPB, otherwise USBASPI.SYS, DI1000DD.SYS
|
||||
won't like us. From Lucho: use DiskTransferBuffer for deblock_buf.
|
||||
+ Changes Lucho
|
||||
* docs/fdkernel.lsm, stacks.inc, version.h,
|
||||
entry.asm, inthndlr.c, io.asm, nlssupt.asm: no need to preserve
|
||||
high part of ecx for Borland, ebx for MSVC
|
||||
* device.h, dsk.c, init-mod.h, ioctl.c: MSC fixes and small cleanup
|
||||
* ioctl.c: Cache attr and control flow optimizations (~120 bytes)
|
||||
* device.h, dsk.c, ioctl.c: deal with the correct
|
||||
structure for generic and query ioctls. Fixes issues with
|
||||
3rd party device drivers (or ones that use dsk.c)
|
||||
* dosfns.c, inthndlr.c, proto.h: Merge dosmkdir and dosrmdir
|
||||
* config.c: strcasecmp and set_strategy common code optimizations.
|
||||
* main.c: Add necessary cast for BC
|
||||
* portab.h: Avoid problem with BC declaring __emit__, en/disable twice.
|
||||
* dsk.c: DJ mechanism without memcpy.
|
||||
* newstuff.c: replace loops by fmemset/fmemcpy (43 bytes)
|
||||
* dosfns.c, fatdir.c, fcbfns.c, ioctl.c: Some small cleanups.
|
||||
* config.c: GetNumArg and misc other cleanups
|
||||
* time.h, fatfs.c: converted TM_ENCODE into a function.
|
||||
* inthndlr.c, proto.h, fatfs.c: Inlined dos_setdta.
|
||||
Various bug fixes and cleanups from Lucho and Arkady.
|
||||
* inithma.c: moved fmemcmp's into a checkHMA function.
|
||||
* inithma.c: HMAFree == 0xfff0 - bytesToAllocate
|
||||
is valid and may happen if the buffers occupy exactly all HMA
|
||||
space up to and including the last byte at ffff:ffff. Failing
|
||||
caused all buffers to go low ...
|
||||
* inthndlr.c: cleanups (merge common code into long_check and
|
||||
short_check). Made int21/3301,2e,54 consistent with MSDOS
|
||||
behaviour.
|
||||
* globals.h, task.c, main.c: Convert setvec into a function
|
||||
for the resident code
|
||||
+ Changes Arkady
|
||||
* initdisk.c: initdisk optimizations (65 bytes) and is_suspect fix.
|
||||
* config.c, init-mod.h, intr.asm: optimized allocmem()
|
||||
* fattab.c, kernel.asm: optimizations
|
||||
* main.c: Make signon one big printf function call.
|
||||
* ioctl.c: bugfix for INT21/440b (change NetRetry if DX is _non_zero).
|
||||
* inthndlr.c: cntry == 0 doesn't make sense for Set Country
|
||||
Information. Fix int21/5e02+
|
||||
* sys/talloc.c: Turbo C really wants unsigned __brklvl. Only shows
|
||||
up if you enable stack checking.
|
||||
+ Changes Bart
|
||||
* memmgr.c, proto.h, inthndlr.c: DosUmbLink no longer
|
||||
tries to merge free blocks. Also cleaned up a bit.
|
||||
* inthndlr.c: Fix int21/3302 (the swap was wrong, Lucho & Bart)
|
||||
* config.c: Pointer-ise specificCountriesSupported accesses.
|
||||
* config.c: Reorganized GetBiosKey a bit -- inlining
|
||||
GetBiosTime saves a slight amount of code, converted timeout < 0
|
||||
to a blocking read instead of polling.
|
||||
* config.c: Use strcaseequal instead of strcasecmp since we
|
||||
never care about order anyway.
|
||||
* chario.c: Fix problem with redirected input and
|
||||
int21/ah=0a (debug < foo.txt) -- could get you an invalid opcode!
|
||||
* console.asm, main.c, prf.c: Use int29 for kernel console
|
||||
output. Enables ansi escape sequences in config.sys once you load
|
||||
nansi.sys. It also saves a couple of bytes.
|
||||
* newstuff.c, proto.h: made dosmktmp to return a long:
|
||||
consistent with DosOpen et al and avoids the cast.
|
||||
* mkfiles/tc2.mak: Let TC2 warn for the utilities.
|
||||
* config.c: Disabled EBDA moves by default. Automatic EBDA
|
||||
moves now happen using switches=/e:-1
|
||||
* config.c: Pointer-ize MenuStruct[MenuSelected]... (from
|
||||
Lucho). and InstallCommands[i]. (from Bart). Some other small
|
||||
optimizations.
|
||||
* memmgr.c: Some small optimizations (46 bytes) and dead
|
||||
code removal from Lucho and Bart
|
||||
* init-mod.h: Need to define strchr to init_strchr otherwise
|
||||
the wrong one may be called.
|
||||
* initdisk.c: Do a bit of printf merging.
|
||||
* filelist, drivers/makefile, init-mod.h, inthndlr.c,
|
||||
task.c, globals.h, main.c: Convert getvec into a C function.
|
||||
* int2f.asm: Clean up int2f assembly a bit (merge some
|
||||
common bits, clarify label names)
|
||||
* fatfs.c, fattab.c: fattab.c now remembers if the old FAT
|
||||
entry was free or not, so the free space adjustment could be
|
||||
moved back to fattab.c.
|
||||
* init-mod.h: Replaced setvec macro by a function.
|
||||
* entry.asm, inthndlr.c: Made int21/ah=25,35 reentrant.
|
||||
Solves problem with Intel PRO/1000 driver.
|
||||
* portab.h, globals.h, main.c: Initialise all int
|
||||
vectors except the ones at 70:xxxx using a table. Convert setvec
|
||||
into a function that disables/enables ints (init code only for
|
||||
now, resident code will follow later); cli/sti (disable/enable)
|
||||
are now macros (inlined).
|
||||
* fnode.h, fatdir.c, fatfs.c: dir_read() no longer updates the
|
||||
diroff counter. This eliminates the NEW field,
|
||||
simplifies remove_lfn_entries(), and avoids a bug if you delete
|
||||
the first entry in the root directory on FAT32.
|
||||
* fattab.c: Stop abusing "idx". The OW optimizer likes this better,too.
|
||||
* fattab.c: Clean up FAT12 handling -- there's a portable
|
||||
approach that's small too.
|
||||
* fattab.c: Inlined much of getFATblock() into link_fat.
|
||||
Saves the idx reference. The second call (for a FAT12 entry that
|
||||
is divided in two sectors) can be much simpler, no need to
|
||||
recalculate. Merged next_cluster and link_fat into one
|
||||
function depending on a special Cluster2 value.
|
||||
* fattab.c: Calculate the nibble/word/dword index of the FAT
|
||||
entry in the sector centrally in getFATblock.
|
||||
* fattab.c: "clussec" can be of CLUSTER size if we divide by
|
||||
an adjusted "words per sector"(FAT16), or "dwords per
|
||||
sector"(FAT32) value instead of multiplying it first. For FAT12
|
||||
the *3/2 works out a little differently: here we first multiply
|
||||
by 3 and then divide by the number of "nibbles per sector".
|
||||
* main.c: Config.cfgInitTail is a pointer now so sizeof
|
||||
isn't good. Just using strcpy helps F5 and F8.
|
||||
* main.c: "copyright" is near now so we have to use %s and not %S
|
||||
* blockio.c, dosfns.c, int2f.asm, network.c, proto.h, task.c:
|
||||
reduced the number of network redirector functions in
|
||||
int2f.asm. The remote_ functions (with one far pointer
|
||||
argument) are now called with the help of a
|
||||
network_redirector() wrapper in C by one multiplex function
|
||||
using a generic void *arg argument to pass the third
|
||||
parameter which can be various things.
|
||||
Split int2f.asm functions, don't let them preserve as many
|
||||
registers, use pascal calling convention for the "open"
|
||||
(but really: multiplex) function.
|
||||
* dsk.c: floppy determination type optimization for format --
|
||||
based on Arkady's suggestions a long time ago.
|
||||
+ a few other small optimizations (~70 bytes total).
|
||||
2004 Apr 17 - Build 2034
|
||||
-------- Bart Oldeman (bart@dosemu.org)
|
||||
* break.c, chario.c, inthndlr.c, proto.h: Improve ctrl-c/ctrl-break
