2006 May 20 - Build 2036 cvs and 2037 test
-------- Eric Auer (eric@coli.uni-sb.de)
WARNING: This changelog entry is a draft! The cvs log contains
data for both HEAD and UNSTABLE branch while a cvs checkout
seems to return only the HEAD branch. This file history.txt
should describe "2036 cvs" HEAD and "2037 test" UNSTABLE
separately rather than in one merged changelog item.
In addition, the "Changes Eric" items yet have to be ported to
the UNSTABLE branch and the version.h for UNSTABLE should say
"03 Mar 2006" "2037 test" (revision 37)...!
Most recent changes to source code (see version.h) are:
HEAD 9 Sep 2005 (not counting the Korean stub and execrh change
by Eric, and not counting the version number change itself)
UNSTABLE 3 Mar 2006 (includes SYS changes, more Win3 support,
COM port output for debug print, the SHARE tool...)
The head to unstable diff in general is quite large. As a rule
of thumb, use UNSTABLE if you need NLSFUNC or Win3 386 mode or if
you need a very new kernel, and use HEAD if you need stability.
+ Changes Jeremy
* build.bat, config.b: UPX and WIN3 build options, for BUILDALL
* boot/oemboot.asm: set backup boot sector on FAT32, add update
option, fix oemboot to work with msdos 7+, in UNSTABLE branch.
* docs/bugs.txt: update Bugzilla URL
* docs/config.txt: document SWITCHES, based on suggestions from Eric
* docs/contrib.txt, docs/fdkernel.lsm: new email address
* docs/sys.htm, docs/sys.txt: see oemboot.asm
* docs/sys.txt: better check for valid backup boot sector # and add
option to skip setting it
* hdr/debug.h, kernel/prf.c: slight cleanup, send debug prints to COM
port, allow printf to work correctly when SS!=DS, debug changes
* hdr/device.h: add comments about what flags mean
* hdr/portab.h: from dev: add MK_PTR and MK_SEG_PTR macros
add/use halt() wrapper for issuing "hlt" asm instruction
* hdr/version.h: update version to 2035b-cvs (= not a release yet)
* kernel/config.c: fix read calls to detect error, from Eric / Brad
* kernel/console.asm, newstuff.c, prf.c, task.c: compile time option
to send debug output to COM port ("serial debugging console")
* kernel/dosfns.c: do not compares filenames to name field in block
devices, extra win3 support, misc debug output changes, IsDevice
should not compare filenames against block device driver headers
* kernel/dsk.c: works towards better SS!=DS support, centralized
debug macros, some comments
* kernel/entry.asm: more win3 support, debug output changes, comments
* kernel/execrh.asm: protect 386 registers, using hdr/stacks.inc
macros (Watcom: FS, GS Others: high 16 bits of EAX EDX, for MSCL8
also ECX, for BC5 also EBX), for ALL device driver calls. Without
this, some versions of free-EMM386 crash 386 optimized kernels.
See list archives 24 Jul 2005 and later.
* kernel/fatfs.c: don't leave fd open when failing DIR bit check
bug 1874 fix, do not consider setting DIR bit an error for
int 21/4301=set attribute, if really is a directory
Added some disabled debug messages, improved win3 support.
* kernel/init-mod.h: allow printf to work correctly when SS!=DS
* kernel/initdisk.h: insure bpb_huge is initialized (zeroed) [merge
from dev kernel], fake floppy ddt so hd access works correctly on
floppyless systems, based on suggested fix from Eric
* kernel/int2f.asm kernel.asm main.c: initial BIOS disk int 13h wrapper,
only passively detects and notes floppy disk change, more win3 support
* kernel/inthndlr.c: potential fix for spurious near fnodes!=0 msg with
shsufdrv and >2 near fnodes in use for bug 1879, use halt() wrapper,
more win3 support, some debug output changes.
* kernel/intwrap.asm: assembly glue to wrap misc interrupts with C
handler, cleaner push immediate from Arkady and note big bug to be
fixed, later moved to UNSTABLE branch (also affects makefile)
* kernel/proto.h: fix prototype, add FAR
allow printf to work correctly when SS!=DS
* mkfiles/generic.mak: undo a local only change, build list option
is proper way to do this. more win3 support, upx build option.
* mkfiles/watcom.mak: allow printf to work correctly when SS!=DS
* share/MAKEFILE, share/share.c, share/share.hlp: FreeDOS SHARE
(initial revision, later moved to UNSTABLE branch)
* sys/fdkrncfg.c: sync printf prototypes (uncorrupt executables)
* sys/sys.c: sync printf prototypes (uncorrupt executables)
better check for valid backup boot sector # and add option to skip
setting it. set backup boot sector on FAT32, add update option,
fix oemboot to work with msdos 7+
+ Changes Eric
* kernel/globals.h changed the os_release version message to be
"build 2036 cvs [version Sep 09 2005 compiled May 20 2006]" as
opposed to the old
"version 1.1.35 (Build 2035b-cvs) [Jul 23 2005 12:34:56]"
-> removed the "1.1.35" and compile TIME, added SOURCE DATE
* hdr/version.h removed some no longer used version defines
Changed build to "2036 cvs" (revision 36)
WARNING: Version should be "2037 test" (revision 37) for UNSTABLE!
* docs/history.txt: summarized log -d '>Feb 25 2005' kernel for this
WARNING: some of the described changes might be available only
in the UNSTABLE cvs branch (like SYS OEMBOOT, Win3, COM port
output for debug print, the SHARE tool, ...)
* kernel/execrh.asm: removed the "protect 386 registers" patch
again, a fixed version of free-EMM386 is available. This reduces
device driver call overhead in terms of CPU and stack usage.
Older EMM386 versions destroyed eax ebx ecx edi esi ebp fs gs,
now go_driver_entry in emm386.asm saves those registers. Only the
INIT was broken, but the execrh.asm patch protected ALL functions.
* share/share.c: changes to reduce TSR memory footprint
* kernel/inthndlr.c: added stub for function 0x6301/0x6302 Korean
Hangul keyboard input methods (0x63xx is DBCS support related)
* docs/intfns.txt: updated list of supported DOS functions. When
DOSLFN is loaded for int 21.71, only remaining unsupported int
21 functions are 21.4b05 (set execution state), int 21.63xx
(DBCS / Korean Hangul, see above) and int 21.5d01 - 21.5d05
(close files by name/computer/task, list open files, commit all)
* made linebreaks in all batch files use CR LF, as Unix line breaks
confuse command.com, leading to "early abort" or "endless loop"
+ Changes Lucho
* kernel/chario.c: Fix Ctrl-Z bug and retro-optimise a bit
* kernel/config.c, sys/sys.c: Fix BC 3.1 CONFIG.C compile and
SYS Abnormal Program Termination error for BC
* sys/sys.c: fix update option (compared too many characters)
+ Changes Eduardo
* kernel/config.c: fix Spanish (34, not duplicate of 33)
