* [ipc/*]
New directory. This directory contains the new inter-wine
communications support. It enables DDE protocols between two wine
instances. Currently it is limited to DDE, but can be enhanced to
support OLE between 2 different wine instances. This is very
important for libwine.a DDE/OLE support.
* [tools/ipcl]
A script to delete garbage IPC handles (shared memory, semaphores
and message queues). The current inter-wine communication is not
perfect, and sometimes leaves garbage behind.
* [if1632/relay.c] [include/atom.h] [include/global.h]
[loader/selector.c] [loader/task.c] [loader/module.c]
[loader/signal.c] [memory/global.c] [misc/atom.c]
[windows/class.c] [windows/message.c] [windows/win.c]
[Imakefile]
Hooks for inter-wine DDE support, current Global.*Atom functions
renamed to Local.*Atom since Global.*Atom are used for Inter-Wine
DDE communication. (The first call to these functions sets up the
IPC structures - which otherwise cause unneeded overhead.
Mon Jul 17 19:55:21 1995 Alexandre Julliard <julliard@sunsite.unc.edu>
* [controls/menu.c]
Don't crash if a NULL string is passed to menu functions.
* [memory/selector.c]
We now use a bit in ldt_flags_copy to indicate free LDT entries.
Fixed a bug in SELECTOR_ReallocBlock that could cause it to
overwrite valid LDT entries when growing a block.
* [miscemu/instr.c]
Emulate int xx instruction by storing the interrupt vector in
CS:IP and returning directly. This allows a program to install an
interrupt vector.
* [windows/win.c]
Added function WIN_GetTopParent to get the top-level parent of a
window.
Sun Jul 16 18:17:17 1995 Gregory Trubetskoy <grisha@mira.com>
* [loader/resource.c]
Added LoadIconHandler. It doesn't do anything yet, but now you
can use borland help files with winhelp.exe.
Sun Jul 16 11:58:45 1995 Anand Kumria <akumria@ozemail.com.au>
* [misc/main.c]
Fixed to return 386 Enhanced mode correctly. Also return the same
type of CPU, for both Enhanced and Standard mode, namely a 386.
Sun Jul 16 00:02:04 1995 Martin von Loewis <loewis@informatik.hu-berlin.de>
* [Configure] [include/options.h] [include/wineopts.h]
[misc/main.c][misc/spy.c]
Removed support of spy file. Redirected spy messages to stddeb.
Removed -spy option. Added -debugmsg +spy option.
* [debugger/dbg.y][debugger/debug.l]
Enabled segmented addresses (seg:offs) for break and x commands.
* [if1632/gdi.spec] [objects/region.c] [windows/graphics.c]
[include/region.h]
FrameRgn, REGION_FrameRgn: New functions
* [if1632/kernel.spec]
IsWinOldApTask: Return false
* [if1632/mouse.spec]
CplApplet: Removed
* [if1632/user.spec] [windows/win.c]
ShowOwnedPopups: New function
* [if1632/winsock.spec] [misc/winsocket.c]
inet_addr, select: New prototypes in relay code
Fixed memory layout for netdb functions (getXbyY).
WINSOCK_ioctlsocket: Translated FIONREAD, FIONBIO, and FIOASYNC
* [objects/clipping.c]
RectVisible: Fixed call to LPToDP
* [rc/winerc.c]
main: Removed extra argument to getopt for Linux.
Tue Jul 11 00:14:41 1995 Bernd Schmidt <crux@pool.informatik.rwth-aachen.de>
* [controls/listbox.c]
Yet another fix for ListBoxDirectory().
* [loader/module.c] [if1632/kernel.spec]
Make GetModuleHandle() accept instance handles as parameter.
* [if1632/relay.c] [loader/task.c]
Put a magic cookie at the bottom of the 32 bit stack, and check on
each return from a 32 bit function whether it's still there. Complain
if it's not.
* [if1632/user.spec]
Wrong entry for CloseDriver().
* [misc/dos_fs.c] [loader/task.c] [include/dos_fs.h] [misc/file.c]
[miscemu/int21.c]
Large parts of dos_fs.c simplified. Changed it to use one
current drive/directory per task, which is set to the module path on
task creation.
Prevent CorelPaint from closing stdin.
open() with O_CREAT set must be passed three parameters.
DOS FindFirst()/FindNext() could crash when FA_LABEL was set. Fixed,
it's in DOS_readdir() now.
* [misc/profile.c]
Some badly written software (Lotus Freelance Graphics) passes a bogus
size parameter that caused Wine to write off the end of a segment.
Fixed. (It's probably too paranoid now.)
* [multimedia/mmsystem.c] [multimedia/time.c] [multimedia/joystick.c]
[multimedia/Imakefile] [if1632/winprocs.spec]
16 bit entry point for MMSysTimeCallback.
Split off time.c and joystick.c from mmsystem.c.
* [objects/dib.c]
GetDIBits(): call XGetImage() via CallTo32_LargeStack.
* [windows/cursor.c]
DestroyCursor(): do nothing for builtin cursors.
* [windows/mdi.c]
Half of WM_MDISETMENU implemented.
* [windows/win.c]
EnumWindows() and EnumTaskWindows() never enumerated any windows.
Fixed.
* [windows/*.c]
Fixed GetParent() to return correct values for owned windows.
* [windows/message.c]
Don't try to activate disabled top-level windows.
* [windows/nonclient.c]
Work around a bug in gcc-2.7.0.
* [tools/build.c] [include/stackframe.h] [memory/global.c]
[loader/task.c] [memory/selector.c]
Some Visual Basic programs (and possibly others, too) expect ES to be
preserved by a call to an API function, so we have to save it.
In GlobalFree() and FreeSelector(), we must clear CURRENT_STACK16->es
to prevent segfaults if ES contained the selector to be freed.
Sun Jul 9 20:21:20 1995 Jon Tombs <jon@gtex02.us.es>
* [*/*]
Added missing prototypes to header files and relevant includes
to reduce compile time warnings.
Sun Jul 9 18:32:56 1995 Michael Patra <micky@marie.physik.tu-berlin.de>
* [configure.in] [include/config.h] [*/Makefile.in]
New configuration scheme based on autoconf.
Sat Jul 8 14:12:45 1995 Morten Welinder <terra+@cs.cmu.edu>
* [miscemu/ioports.c]
Revamp to have only one in- and one out- variant, both really
implemented.
* [miscemu/instr.c]
INSTR_EmulateInstruction: Use new ioport interface. Implement
string io. Correct instruction pointer for 32-bit code.
* [include/miscemu.h]
Update port function prototypes.
* [include/registers.h]
Defined FS and GS.
Sat Jul 8 13:38:54 1995 Hans de Graaff <graaff@twi72.twi.tudelft.nl>
* [misc/dos_fs.c]
ChopOffSlash(): A path consisting off a single slash is left
intact, and multiple slashes are all removed.
