2009 Aug xx - Build 2039
-------- Jeremy Davis, Bart Oldeman
+ Changes Jeremy
* r1494, 1483 docs/sys.txt, sys/sys.c: update documentation to
include new options; add option to sys to force LBA or CHS
usage, allow using BIOS specified boot drive # on floppy,
add verbose output (debug prints), and reorder some steps in
copy() to avoid some unnecessary disk swaps on single drive systems
* r1493 boot/boot.asm: add comment about location that may be
modified by sys (and some whitespace changes due to editor)
* r1492 boot/makefile: create list file when assembling boot sectors
* r1489 kernel/main.c: update copyright year, add some comments
* r1488 kernel/kernel.asm: mark unused space in kernel for unused win
compatibility structs
* r1487 hdr/lol.h, hdr/win.h: comment/structure info update
* r1486 hdr/process.h: comments added
* r1485 hdr/device.h: comments added
* r1484 hdr/cds.h: update comments
* r1483 docs/sys.txt: update sys usage documentation
* r1482 boot/boot.asm, boot/makefile, boot/oemboot.asm,
build.bat, default.bat, hdr/debug.h, kernel/{dosfns.c,init-mod.h,
initdisk.c,inthndlr.c,prf.c,proto.h},sys/{fdkrncfg.c,makefile,sys.c}:
update sys to current version, adjust printf to support
percent modifier, consistent prototype, and handle text not in
current segment (FAR *) better, merge part of simplified debug (via
prints) support
* r1467 kernel/makefile, mkfiles/generic.mak: update build process to
include country.sys
* r1466 kernel/country.asm: sync country source with latest from
eduardocasino.es site
* r1465 kernel/country.asm: add source for country.sys from dev
branch
* r1456 hdr/version.h, kernel/globals.h: simplify how version
specified, enable SVN builds with revision#
* r1455 build.bat: add convenience options to build.bat for setting
various defines
* r1454 default.bat: clear some additional env variables
* r1431 kernel/makefile, utils/exeflat.c: More verbose output of UPX
method (sys or exe) used and fix case without UPX so kernel boots.
* r1385 docs/fdkernel.lsm, hdr/version.h: update version # in
preparation for next release and to avoid confusion between svn and
release kernels
+ Changes Bart
* r1491 hdr/debug.h, kernel/{init-mod.h,kernel/int2f.asm,nls.c,prf.c,
proto.h}, sys/{fdkrncfg.c,sys.c}: Use near pointers for printf()s
where possible. Problematic is only the case where SS!=DS (which
happens sometimes in resident code), in which case va_list/va_arg
need to use FAR pointers. DS!=DGROUP never works, so I corrected
that for NLS_DEBUG, by setting DS in int2f.asm.
* r1490 kernel/fatfs.c: Check the BPB instead of the DPB for FAT32
after a BUILDBPB device call, as the DPB may still be uninitialized
at this point. Fixes FAT32 drives in USBDRIVE (http://bretjohnson.us)
* r1480 utils/exeflat.c: Corrected a bug in exeflat: it was writing
32 bytes too many from possibly unexisting buffers after compressing
exe files.
* r1479 kernel/{initdisk.c,newstuff.c}: Corrected DEBUG #if to
#ifdef for Turbo C and corrected debug printfs in truename().
* r1478 kernel/newstuff.c: Simplified truename(): eliminated the
addSep state by adding a backslash in every new segment, including a
trailing backslash. Simplified . and .. logic. Converted switch to if
because there were few cases left.
* r1477 kernel/dosfns.c: DosChangeDir can only return DE_PATHNOTFND
in case of error, so force that error code.
* r1476 kernel/dosfns.c: Remove the wildcard check for DosChangeDir()
because truename() already does that.
* r1475 kernel/newstuff.c: Use simpler code for copying the current
directory constructing the "truename": instead of fmemcpy followed by
strcpy, just use strcpy. Also use the near TempCDS more.
* r1474 kernel/newstuff.c: Unify parse_name_ext for name and
extension and inline this function into truename(). This is an
optimization (200 bytes).
* r1473 kernel{fatdir.c,fatfs.c,newstuff.c}: If the current directory
is no longer valid, call dos_cd() for the root to update the CDS
cluster. Call media_check explicitly in truename() as a central
first and only place in directory-using DOS calls (except
DosFindNext) to call it.
* r1472 kernel/{dosfns.c,newstuff.c}: The original DosGetCuDir
is now inlined in truename(). DosGetCuDir now does truename("D:",
CDS_MODE_SKIP_PHYSICAL), and this mode was changed to no longer call
QRemote_Fn (int2f/ax=1123).
* r1471 kernel/newstuff.c: Fix truename("C:") where the current
directory is different from the root: then it should not append a
backslash.
* r1470 kernel/{inthndlr.c,makefile}: Turbo C 2.01 and Linux
cross-compilation compatibility fixes.
* r1469 kernel/{inthndlr.c,task.c}: For self-owning PSPs do
everything that a normal exit does except for closing files and
releasing memory (see RBIL). Thanks to Christian Masloch.
* r1468 kernel/fatdir.c: Fix problem with cd\ reported by
ibid_ag@lavabit.com on the mailing list.
* r1458 kernel/{blockio.c, fatfs.c, proto.h}: In case of
"not sure" if the removable media has changed, the IBM PCDOS
technical reference says to call BLDBPB if there are no used buffers,
so we only do it then, instead of flushing the buffers.
* r1457 hdr/{xstructs.h, inthndlr.c}: Merged int21/ax=7304,
subfunctions 3 and 4, which work very similarly.
* r1453 kernel/fatfs.c: Set the clean bit also on created/replaced
files, not just opened files, so the directory entry is only updated
after they are written too. Fixes SF bug #2380531.
* r1452 kernel/initdisk.c: Use a better formula for calculating FAT12
clusters, by multiplying nominator and denominator by 3.
* r1451 kernel/{fatfs.c, initdisk.c}: initdisk: further optimizations
in CalculateFATData(): merging the FAT16 & FAT32 loops.
fatfs: #if DEBUG fix.
* r1450 kernel/initdisk.c: Optimized initdisk.c by using constants
instead of variables where possible.
* r1449 kernel/config.c, kernel/config.h: Removed unused config
variables and don't detect 'y' and 'n' if we're using toupper anyway.
* r1448 hdr/{fat.h, fatfs.c}: Cluster optimizations, mainly for FAT32
eliminated checkdstart, replaced (cl == FREE || cl == 1) by (cl <= 1),
UWORD cluster cast for FAT12/16, and merge if branches for link_fat().
* r1447 kernel/fatfs.c: Merged if status==S_OPENED logic in dos_open,
cache dir_attrib, and remove unnecessary init to 0.
* r1446 kernel/config.c: Make the built-in COUNTRY table more compact
and allow to merge duplicate strings for error message.
* r1445 kernel/fatfs.c: Optimization: changed find_fname() to call
split_path() because find_fname was always preceeded by split_path().
The return code is now an error code, DE_FILENOTFND, DE_PATHNOTFND,
or SUCCESS, depending on the failure.
* r1444 kernel/{fatdir.c, fatfs.c, proto.h}: Added a
split boolean argument to dir_open so the trick with setting the
dir/filename separator to 0 can be avoided, and we don't need to
calculate its location in split_path(). Without the trick many more
char * path arguments in the kernel can become "const char *".
* r1443 utils/exeflat.c: Use tmp.exe instead of tmp$$$$$.exe -- the
Linux cross compilation really has trouble without quotes because $$
can be expanded as a shell variable when passed to system().
* r1442 kernel/{dosnames.c, fatfs.c, makefile, proto.h}:
Remove dosnames.c and inline ParseDosName, because there is only one
user left (split_path()) which only uses it to find out if the path
ends in a backslash and the length of the directory part.
* r1441 kernel/{dosnames.c, fatdir.c, fatfs.c, proto.h}:
dos_findfirst() now uses split_path(). The only thing
that needed to be added was the need to check for "d:\" paths which
return DE_NFILES. Also, findfirst("d:\nonexist\*.*",D_VOLID) should
fail even if it actually searches in d:\.
* r1440 kernel/{dosnames.c, newstuff.c}: The invalid pathname
character detection is moved from ParseDosName (dosnames.c) to
truename (newstuff.c), because TRUENAME should check these characters
before passing paths on to fatfs.c & fatdir.c.
* r1439 kernel/fatdir.c: Corrected the if-statement && logic for
attributes in the findnext loop.
* r1438 kernel/{dosfns.c, fatdir.c}: Make findfirst/findnext
more MSDOS compatible:
* ignore 0x40 (D_DEVICE) in search attribute.
* if you specify D_VOLID + one or more of D_HIDDEN, D_SYSTEM, and
D_DIR you will get files *and* volume labels in the specified
directory, not forced to the root directory.
* VOLID searches must look at the search pattern name too,
or do not match.
* r1437 kernel/{dosfns.c, fatfs.c}: For read/write don't update
sft_posit in dosfns.c anymore so fatfs.c takes care of it.
* r1436 kernel/{fatdir.c, fatfs.c}: Remove usage of the fnode
f_flags field where it is not relevant anymore. Because of the
explicit dir_write() calls we only need them in situations where SFTs
where used, that is for open files but not for directories.
* r1435 kernel/{fatdir.c, fatfs.c}: Eliminate fcbname[] on the
stack: we can use dm_name_pat in the dirmatch structures instead.
* r1434 kernel/asmsupt.asm: %if 0 unused asm functions and fix a
stack return problem with fstrcmp.
* r1433 kernel/{dosnames.c, fatdir.c, fatfs.c, proto.h}:
Split 8.3 FCB-style filename extraction from ParseDosName
into a new ConvertNameSZToName83 function, also used by dir_open().
* r1432 hdr/fnode.h, kernel/{fatdir.c, fatfs.c, globals.h, init-mod.h,
kernel.asm}:
Move the fnode fields f_diroff and f_dirstart into a referenced
directory match structure with fields dm_entry and dm_dircluster.
* r1430 hdr/nls.h, kernel/{config.c, init-mod.h, inthndlr.c, intr.asm,
kernel/nls.c, kernel/nls_hc.asm, kernel/proto.h}:
Ported COUNTRY.SYS support from the unstable branch.
Simple country support is kept: COUNTRY=31 will look for country.sys
but if it does not exist, not complain and load the built-in info.
* r1429 hdr/sft.h, kernel/{dosfns.c, inthndlr.c, proto.h}: Seek changes:
* merge unstable kernel optimizations
* enable seek for int2f/AX=1228
* -1 is a valid offset, so we need to process the return code
seperately
* r1428 kernel/dosfns.c: Merge pop_dmp optimization from the unstable
kernel.
* r1427 kernel/ioctl.c: This change was missed, as the changelog
mentioned it was in 2035a already: r_si/r_di contents added as
documented in PC-DOS Technical Update. I also moved the CharReqHdr
filling in to just before execrh, and made the command table a static
const so it is outside the SDA (OW places it in CONST2).
* r1426 kernel/ioctl.c: Optimization: move the attribute checks down
and localize some variables.
* r1425 kernel/ioctl.c: Streamline ioctl.c code so OW saves 2 more
words of stack.
* r1424 kernel/ioctl.c: r1115 set the dpb_subunit but that was wrong
for get_cds() called from AX=4409. Use a local variable unit to avoid
that, and simplify the AX=4409 logic like in the unstable kernel.
* r1423 kernel/ioctl.c: Inline ioctl helper routine back again. Save
stack by using the dev variable that points to the device smartly.
* r1422 kernel/ioctl.c: Split DosDevIoctl into two calls so execrh
can be called with minimal stack usage. Always return DE_ACCESS when
the device fails instead of DE_DEVICE, as DE_DEVICE is only used for
renames between devices that are not the same.
* r1421 kernel/fatfs.c: Introduce clear_dir() to clear a directory,
this was code shared between dos_mkdir() and extend_dir(). Now
dos_mkdir() calls this function to clear the new directory, and then
creates the . and .. entries using higher level functions instead of
dealing with the blocks directly.
* r1420 hdr/{fnode.h, sft.h}, kernel/{fatdir.c, fatfs.c}: Make
the fnode f_flags completely equal to the SFT sft_flags. Rename
SFT_FDIRTY to SFT_FCLEAN to avoid confusion.
* r1419 hdr/fnode.h, kernel/{fatdir.c, fatfs.c}: Eliminate the
fnode F_DDIR flag which has no SFT equivalent: f_sft_idx==0xff can do
the same. rwblock() is never called for directories so the checks
could be removed.
* r1418 kernel/fatfs.c: Flip target and source checks to avoid
calling ParseDosName for in-directory renames. Do not allow to rename
directories between different directories.
* r1417 kernel/fatfs.c: RENAME: if the source and target directories
are the same, rename the directory entry in-place instead of creating
a new one and deleting the old one. Fixes archived bugzilla bug:
http://www.freedos.org/bugzilla/cgi-bin/show_bug.cgi?id=1908
* r1416 kernel/fatfs.c: Change dos_rmdir to only use 1 fnode. It now
first checks if the directory is empty and then opens the parent and
deletes the real directory. No longer returns DE_FILENOTFND(2), but
return DE_PATHNOTFND(3) instead.
* r1415 hdr/dirmatch.h: Cleanup dirmatch.h: make attributes and size
unsigned, and make the unused dm_flags field reserved.
* r1414 kernel/{dosfns.c, proto.h, task.c}: Introduce get_cds1 to merge
common code that checks for 0=default_drive,1=A,etc.
Make load_transfer() static.
* r1413 kernel/chario.c: Inline cooked_write_char() into cooked_write().
* r1411 kernel/fatfs.c: Fix compilation with Turbo C.
* r1410 kernel/{fatdir.c, fatfs.c, proto.h}: Eliminate dir_close().
Its only purpose left was to flush buffers, which isn't necessary
after just open/read, so we can move that to dir_write().
* r1409 kernel/{dosfns.c, fatfs.c}:
Move the open/creat access checks to more efficient places.
* r1408 kernel/fatfs.c: Make merge_file_changes more direct dealing
with SFTs and merge the "close open files setfattr wants to change"
functionality there.
* r1407 kernel/dosfns.c: Eliminate DosGetFile -- it is no longer
necessary because the filename is already copied from the fnode.
* r1406 kernel/dosfns.c: Fix a regression with sft_flags overwriting
what dos_open wrote so file dates/times would always be updated, even
for reads!
* r1405 kernel/{dosfns.c, fatdir.c, fatfs.c, fcbfns.c, proto.h}:
Eliminate dos_setfsize, dos_setftime, and dos_lseek, by just using
the SFT. dos_setfsize still needed to merge changes for SHARE so the
call was replaced by a new dos_merge_file_changes() call.
* r1404 hdr/fnode.h, kernel/{fatdir.c, fatfs.c}: Eliminate
xlt_fd(), save_far_f_node(), and the redundant fnode f_mode field.
* r1403 kernel/{dosfns.c, fatfs.c}: Let merge_file_changes
operate directly on the other SFTs. dos_setfattr with SHARE now
closes open SFTs referring to that file in compat mode.
* r1402 kernel/fatfs.c: Fix SFT/fnode fields so the SHARE related
functions is_same_file() and merge_file_changes() work.
* r1401 hdr/fnode.h, kernel/{fatfs.c, globals.h}: Remove
redundant checks for fnodes==0 since the checks are done in dosfns.c.
Replace global f_nodes[] array by f_sft_idx fields in the fnodes.
* r1400 hdr/sft.h, kernel/{dosfns.c, fatfs.c, fcbfns.c, proto.h}:
Eliminate the sft_status field as it is now equal to the SFT index.
* r1399 kernel/{dosfns.c, fatfs.c, proto.h, task.c}:
Eliminate dos_getftime, dos_getfsize, and dos_getfattr_fd, because we
can now get these properties directly from the SFT.
* r1398 hdr/fnode.h, kernel/{fatdir.c, fatfs.c, proto.h}:
Eliminate f_count field in fnodes and some no-op functions.
* r1397 hdr/{fnode.h, lol.h}, kernel/{config.c, dosfns.c, fatfs.c,
globals.h, kernel.asm, proto.h}:
This is the main change to eliminate far fnodes. SFT info is copied
from and to the two near fnodes. Some cleanups still follow.
* r1396 hdr/sft.h:
Make the SFT DOS 4+ compatible and change fields to be unsigned.
* r1395 kernel/dosfns.c:
Handle sft_count before calling dos_open and after calling dos_close
so the SFT is open for longer, during fatfs.c operations.
* r1394 kernel/prf.c: Fix compilation with -DDOSEMU set.
* r1393 kernel/{dosfns.c, fatfs.c}: Handle dos_getfattr and
dos_setfattr directly at the directory level, instead of opening the
file, to avoid needing to claim SFTs in later changes. Clarify and
implement parts of the correct SHARE behaviour.
* r1392 hdr/fat.h, kernel/{fatdir.c, fatfs.c, proto.h}:
On close or commit, only update those directory entry fields that
have an SFT equivalent. The rest stays unmodified on disk.
* r1391 kernel/{fatdir.c, fatfs.c}: Use explicit dir_write()
instead of letting dir_close() do the writing. This is to prepare for
an updating version to deal with SFTs.
* r1390 hdr/fnode.h, kernel/fatdir.c: Add f_dirsector (sector
containing dentry) and f_diridx (index within sector) fields to the
fnode, to make fnodes more compatible with SFTs. Use them to simplify
dir_read() and dir_write().
* r1389 kernel/{fatdir.c, fatfs.c, globals.h, inthndlr.c, lfnapi.c,
proto.h}: Force near fnode use to use either fnode[0] or fnode[1]
instead of the allocation scheme. This eliminates the checks
done in inthndlr.c because the f_count field is no longer checked.
* r1388 makefile, mkfiles/owlinux.mak: Change Linux makefiles to only
update what is necessary for subsequent makes.
* r1387 config.m, docs/build.txt, drivers/makefile, kernel/{makefile,
segs.inc}, makefile, mkfiles/{generic.mak, owlinux.mak, watcom.mak},
sys/makefile, utils/{exeflat.c, makefile}:
Add Linux cross-compile capability, using Open Watcom:
* Flip \ to / where possible.
* Introduce $(DIRSEP) (/ or \) for use inside commands in
makefiles where / won't work in DOS.
* Override various settings for Linux in owlinux.mak.
* Add quotes in exeflat.c to avoid shell expansion of $$$$$.
* Let "make all", "make clean", and "make clobber" do the job.
* r1386 utils/echoto.bat: OW 1.8 MS2WLINK is too picky about leading
and trailing whitespace so echoto is changed to not generate any.
