Sat Jul 22 22:39:09 IDT 1995 Michael Veksler <e1678223@tochnapc2.technion.ac.il> * [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.
