Release 980118 Sun Jan 18 17:05:58 1998 Alexandre Julliard <julliard@lrc.epfl.ch> * [include/stackframe.h] [tools/build.c] Some cleanups in stack frame building. * [misc/port.c] Implemented clone() wrapper for libc5 users. * [scheduler/mutex.c] [scheduler/synchro.c] Implemented abandoned mutexes. * [scheduler/process.c] [scheduler/thread.c] We now create a process and a thread structure as soon as possible during initialization. * [scheduler/thread.c] [scheduler/sysdeps.c] Moved system-specific thread handling to sysdeps.c. Fri Jan 16 10:45:15 1998 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [graphics/ddraw.c][include/ddraw.h] Surface handling enhanced. Some stuff already works ;) * [multimedia/dsound.c][include/dsound.h] Implemented using the Open Sound System. Slowly starts to work (sounds terrible for some programs). * [configure.in][multimedia/audio.c][include/config.h.in] Added check for OpenSoundSystem, fixed -lXxf86dga check. Replaced OS #ifdefs by #ifdef HAVE_OSS in mm/audio.c. * [if1632/relay.c][relay32/relay386.c] Do not print control characters for 'str' or 'wstr' args. * [misc/registry.c] "" seems to equals NULL in keynames. Replace where needed. Seems to help the win95 regedit.exe... * [win32/newfns.c] Implemented QueryPerformance* using gettimeofday(2) (should be done using the pentium timers probably). * [tools/ipcl] Removed useless open_pipe construct. Sun Jan 11 17:10:02 1998 Huw D M Davies <h.davies1@physics.oxford.ac.uk> * [objects/region.c] [include/region.h] [graphics/x11drv/clipping.c] Regions are now internal to Wine. The basis of this code is taken from the X11 distribution. GetRegionData() is implemented as is ExtCreateRegion() (without Xforms). CreatePolyPolygonRgn() should behave correctly now. * [objects/metafile.c] [graphics/metafiledrv/graphics.c] [graphics/metafiledrv/init.c] [include/metafile.h] [include/metafiledrv.h] Playback of META_CREATEREGION should now work. Implemented recording of META_CREATEREGION and META_PAINTREGION. * [graphics/x11drv/graphics.c] FillRgn() (and therefore its friends) respect logical co-ords. Wed Jan 7 01:21:45 1998 Steinar Hamre <steinarh@stud.fim.ntnu.no> * [configure.in] [include/acconfig.h] [tools/build.c] Now checking whether to use .string or .ascii. * [configure.in] [include/acconfig.h] [scheduler/critsection.c] Defining union semun if this is not available from header files. * [misc/lstr.c] Moved wine's own header files below <wctype.h> to avoid parse error on Solaris. Sun Jan 4 15:38:07 1998 Andrew Taylor <ataylor@cadvision.com> * [multimedia/mmsystem.c] [multimedia/mmio.c] Implemented mmioSendMessage and rearranged the mmio subsystem in terms of this function. Wed Dec 24 00:51:29 1997 Charles Duffy <cduffy@bigfoot.com> * [windows/clipboard.c] [relay32/user32.spec] GetPriorityClipboardFormat32 now has something other than just a stub. I have no idea if it works (can't test until SetClipboardData is finished) but HEdit likes things a lot more this way.

Release 980118 Sun Jan 18 17:05:58 1998 Alexandre Julliard <julliard@lrc.epfl.ch> * [include/stackframe.h] [tools/build.c] Some cleanups in stack frame building. * [misc/port.c] Implemented clone() wrapper for libc5 users. * [scheduler/mutex.c] [scheduler/synchro.c] Implemented abandoned mutexes. * [scheduler/process.c] [scheduler/thread.c] We now create a process and a thread structure as soon as possible during initialization. * [scheduler/thread.c] [scheduler/sysdeps.c] Moved system-specific thread handling to sysdeps.c. Fri Jan 16 10:45:15 1998 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [graphics/ddraw.c][include/ddraw.h] Surface handling enhanced. Some stuff already works ;) * [multimedia/dsound.c][include/dsound.h] Implemented using the Open Sound System. Slowly starts to work (sounds terrible for some programs). * [configure.in][multimedia/audio.c][include/config.h.in] Added check for OpenSoundSystem, fixed -lXxf86dga check. Replaced OS #ifdefs by #ifdef HAVE_OSS in mm/audio.c. * [if1632/relay.c][relay32/relay386.c] Do not print control characters for 'str' or 'wstr' args. * [misc/registry.c] "" seems to equals NULL in keynames. Replace where needed. Seems to help the win95 regedit.exe... * [win32/newfns.c] Implemented QueryPerformance* using gettimeofday(2) (should be done using the pentium timers probably). * [tools/ipcl] Removed useless open_pipe construct. Sun Jan 11 17:10:02 1998 Huw D M Davies <h.davies1@physics.oxford.ac.uk> * [objects/region.c] [include/region.h] [graphics/x11drv/clipping.c] Regions are now internal to Wine. The basis of this code is taken from the X11 distribution. GetRegionData() is implemented as is ExtCreateRegion() (without Xforms). CreatePolyPolygonRgn() should behave correctly now. * [objects/metafile.c] [graphics/metafiledrv/graphics.c] [graphics/metafiledrv/init.c] [include/metafile.h] [include/metafiledrv.h] Playback of META_CREATEREGION should now work. Implemented recording of META_CREATEREGION and META_PAINTREGION. * [graphics/x11drv/graphics.c] FillRgn() (and therefore its friends) respect logical co-ords.

* NtCurrentTeb (NTDLL.@)
Release 980301 Sun Mar 1 10:45:23 1998 Andreas Mohr <100.30936@germany.net> * [loader/ne_image.c] Fixed problem with weird DLLs (NE_FFLAGS_SINGLEDATA && DGROUP = 0). * [msdos/dosmem.c] Export address for __0000H, too. * [msdos/dpmi.c] Changed MemAlloc functions to return less fragmented addresses. Sat Feb 28 18:50:12 1998 Alexandre Julliard <julliard@lrc.epfl.ch> * [scheduler/process.c] [scheduler/sysdeps.c] Don't use %fs register before threading initialization. Sat Feb 28 14:04:56 1998 Kristian Nielsen <kristian.nielsen@risoe.dk> * [configure.in] [include/acconfig.h] Autoconf macro to check for non-reentrant X libraries. * [windows/winpos.c] In SetWindowPos32(), do not cause WM_SIZE messages when the SWP_NOSIZE flag is specified. This fixes the division-by-zero in Borland C++ 4.0 "Open Project" menu item. Sat Feb 28 13:11:26 1998 James Moody <013263m@dragon.acadiau.ca> * [ole/ole2nls.c] Changed "English" values from German to English. * [files/dos_fs.c] Fixed off-by-one month bug. Fri Feb 27 22:12:01 1998 Douglas Ridgway <ridgway@winehq.com> * [windows/win.c] Fix winelib class menu loading bug. * [include/module.h] [loader/module.c] LoadModule32 should be implemented in terms of CreateProcess. * [programs/view/*] Metafile viewer sample program. * [documentation/wine.texinfo] [documentation/Makefile.in] Improvements and additions, HTML target. Fri Feb 27 04:27:48 1998 Dimitrie O. Paun <dimi@cs.toronto.edu> * [*/*] Switched to the new debug messages interface. For more information please refer to documentation/debug-msgs. Because the new scheme introduces a new semantic level, I had to manually do through about 530 dprintf_xxx! The rest of about 2400 where transformed via a script. Because of the large number of changes that I had to do, some may have not come out as nicely as I wanted them. If this is the case, please let me know. There is a lot of work left to do: -- a few hundred printf's to be converted -- about 2300 fprintf's to be converted -- about 600 FIXME's to be transformed The problem is that in the above mentioned cases, a lot of manual intervention is required because a lot of the information is missing. There are also a lot of other things to be done to the interface and so forth. I have now ideas for a at least a month worth of full time work :) I will proceed with many changes in the next few releases, so please do not start modifing things because there will be a hell of a lot of conflicts. If you have ideas that you want to integrate or you want to work on different things, please coordinate with me. Thu Feb 26 13:04:29 1998 David Lee Lambert <lamber45@egr.msu.edu> * [ole/ole2nls.c] [include/windows.h] First try at OLE date- and time-formatting functions. Wed Feb 25 11:20:35 1998 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [files/*.c] Changed dos device handling, added 'CON' devicehandling. * [graphics/ddraw.c] Bug fixes, some additions. * [if1632/builtin.c][loader/module.c][library/winestub.c] Small hack so we don't need a dummy BUILTIN_LoadModule in winestub.c. * [ole/*][relay32/ole32.spec][if1632/storage.spec] storage.dll started. winword loads documents (saving doesn't work yet, dunno why). Several ole additions, some cleanups and bugfixes. IMalloc16 implemented. * [loader/pe_image.c] Added some comments, fixed circular dll references, fixed modref ordering, fixed tls allocation. * [memory/global.c] Added validity checks before every GET_ARENA_PTR. (several functions rely on Global* return values on invalid handles, like IsTask). Implemented GlobalUnlockFree16. * [memory/virtual.c] Replaced dprintf_virtual by fprintf, so we can do 'info map' again in the debugger. Increase read linesize for Linux2.1 cases. * [misc/cpu.c][misc/registry.c] Moved cpu registry initialization to misc/cpu.c. * [multimedia/dsound.c] Enhanced, replaced GETOSPACE bufferingcheck by SETFRAGMENT. * [relay32/crtdll.spec][relay32/ntdll.spec] Replaced some ptr by respective 'str' and 'wstr' arguments for libc functions. * [scheduler/thread.c] Added some sanity checks to stackallocation, tlshandling fixed. * [tools/build.c] Fixed cdecl argumenttype order (was reversed). * [win32/ordinals.c] Implemented KERNEL_449. * [windows/dinput.c] Some fixes, needs much more work. Tomb Raider2 works with keyboard ;) Tue Feb 24 20:46:37 1998 James Juran <jrj120@psu.edu> * [windows/win.c] Fixed USER32 ordinal numbers in documentation. Sat Feb 21 12:30:38 1998 John Richardson <jrichard@zko.dec.com> * [files/file.c] [include/k32obj.h] [memory/virtual.c] [scheduler/critsection.c] [scheduler/event.c] [scheduler/handle.c] [scheduler/k32obj.c] [scheduler/mutex.c] [scheduler/process.c] [scheduler/semaphore.c] [scheduler/thread.c] Added generic k32obj read and write routines for k32objs that support I/O. * [documentation/console] Updated console docs. * [win32/console.c] Make console work like a k32obj that supports I/O. * [include/windows.h] Make WriteFile and ReadFile take HANDLE32 for handle. Sun Feb 15 14:07:07 1998 Dimitrie O. Paun <dimi@mail.cs.toronto.edu> * [controls/menu.c] [misc/ver.c] [multimedia/dsound.c] [multimedia/joystick.c] [windows/dialog.c] Modified some dprintf_xxx's to prepare them for a new dprintf_ scheme. Basically, I changed the dprintf's that outputed a line with many dprintf calls to do just one dprintf call.
