-----BEGIN PGP SIGNED MESSAGE----- Moin, [crosspost to both wine lists] I am preparing a patch for DirectDraw::SetCooperativeLevel and friends: Some questions from a newbie, so please bear with me: ddraw/user.c has comments like these: /* GetDisplayMode: generic */ /* GetFourCCCodes: generic */ /* GetGDISurface: ??? */ /* GetMonitorFrequency: generic */ /* GetScanLine: generic */ /* GetSurfaceFromDC: generic */ /* GetVerticalBlankStatus: generic */ /* Initialize: generic */ /* RestoreAllSurfaces: generic */ /* RestoreDisplayMode: generic */ /* SetCooperativeLevel: ??? */ * What does the "generic" stand for? Return value? Function class? * It seems that SetCooperativeLevel associates a "value" (or more than one) with the givenwindow handle and TestCooperativeLevel let's you later check this status. Where would I store such a "global" value? * If I understand it correctly, the directx stuff is done by transgaming. Their licence differs from the "normal" wine. (I am really unsure how all these things play together even after readin codeweavers.com, winehq.com and transgaming.com) So, if I send in a patch for that, should I send it to wine-devel-patches? wine-devel? winex-devel? Under what license would it fall? Or does that not matter? I have no idea what hidden snatches are in the transmeta licence, so I would like to use the LGPL. ;) Is there a problem with that for the transmeta guys or for you wine guys? Or would it fall automatically under the transmeta licence, since I am patching their source anyway? (You can tell I am confused ;) * Also, since I am a bit CVS challanged (newbie, I told you ;), is it okay to add my files directly in the CVS source tree with vi(m) and then send you a diff -u patch? Or do I need some CVS magic to do locally? Or just keep the file outside the CVS and then send a patch? Thanx in advance, Te"Wine, I am coooominng!"ls - -- "Why do you go so slowly?

cool font viewer... might make good test case
by Dan Kegel 05 Apr '02

05 Apr '02

FYI... My wife is a Windows user who loves fonts. She never found good free font viewing utilities until today; now she's raving about 'font xplorer lite'. Since it's a free download, it might make a good testcase for Wine's font support. It's at http://www.moonsoftware.com/freeware.asp but I haven't tried it yet. - Dan

Re: ReadFile and WriteFile in overlapped mode

Hi, > I have been looking at those two functions and some specs. > My understanding is that those function do not work at all I haven't tested the current CVS lately, but i can assure you that ReadFile and WriteFile did work at some fairly recent time :-) You may be correct that they do not work in *exactly* the right way, but for most cases they do work. > ever be generated since step be is not performed. Application > doing the following sequence > ReadFile > .. > WaitOnSingleObject > > will wait forever. Some borland Builder classes do this No, it won't because asynchronous reads can be processed during on-alertable waits. The application must call WaitForSingleObject eventually to see f the overlapped operation has finished. > My understanding is that step a should never be done and only > step b. Is that correct ? We need to check if data is pending before returning RROR_IO_PENDING because some applications do this: WaitCommEvent(hComm,&ev,&ov); WaitForSingleObject(ov.hEvent); ClearCommError(hComm,NULL,&cs) len = cs.cbInQue; if(!ReadFile(hComm,buf,len,&count,&ov)) FATAL() You're right that the way wine currently handles this is not erfect, but it will only fail if multiple overlapped operations re done at the same time. Martin Wilck is currently fixing this. > Now, why step b is failing is another story. > > Comments ? It's not perfect, and you're welcome to fix it if you want.

Hi Martin, I think this is a better way to do things, but it might be better to submit this patch against the current CVS rather than against CVS+previous patch.

[PATCH] async IO APCs call check_async_list() directly
by Martin Wilck 04 Apr '02

04 Apr '02

PATCH: async-func.diff This is an improvement over my previous patch (async-struct.diff) in that it does not need the static function check_async_lists in several source files anymore and still achieves DLL separation. The idea is that all async I/O requests use check_async_list as callback function anyway, so that there is no need to pass a function pointer. I discussed the idea with Mike, and he seemed to like it. Patch against: Wine CVS 2002/04/04, with my async-struct patch applied. Test status: Compiles warnings. Tested regular file async IO (ok). Serial port async IO: a test would be desirable. Modified files: include : async.h (remove check_async_list) server : protocol.def (add APC_ASYNC_IO APC type, remove func field for create_async) async.h (remove func field in async struct) async.c (remove references to func field) thread.c (allow NULL function pointer for APC_ASYNC_IO) scheduler : synchro.c (add check_async_list;

freetype.c:1852: conflicting types for `WineEngGetTextExtentPointI'
by Andriy Palamarchuk 04 Apr '02

04 Apr '02

After refreshing today morning from CVS I got the compilation error. The complete error text: freetype.c:1852: conflicting types for `WineEngGetTextExtentPointI' ../../include/font.h:102: previous declaration of `WineEngGetTextExtentPointI' make[2]: *** [freetype.o] Error 1 make[2]: Leaving directory `/mnt/buf/prj/wine/dlls/gdi' make[1]: *** [gdi/gdi32.dll.so] Error 2 make[1]: Leaving directory `/mnt/buf/prj/wine/dlls' make: *** [dlls] Error 2 Huw, can it be because of your yesterday's patch? Other relevant patch is Alexandre's change to configure. Let me know if you need additional information. Andriy Palamarchuk __________________________________________________ Do You Yahoo!? Yahoo!

[PATCH] Move send() functionality to WS2_32 code
by Martin Wilck 04 Apr '02

04 Apr '02

PATCH: Move send() functionality to WS2_32 code In short, does the same to send() that the previous patch did to recv(). For the send() family of functions, WSASendTo() becomes the work horse. All other functions (WSASend(), send(), sendto(), ...) are only wrappers around WSASendTo(). To provide the scatter/gather functionality of WSASendTo(), the Unix system call used as backend is sendmsg() rather than sendto(). Patch against: Wine CVS 2002-04-03, with my previous patch (recv) applied. Test status: Compiles, no warnings. Tested with 16 bit apps: FreeAgent (newsreader), Solstice mail, nslookup, teraterm (telnet) (16 bit apps now call WS2_32 code!)

To provide the scatter/gather functionality of WSARecvFrom(), the Unix system call used as backend is recvmsg() rather than recvfrom(). Patch against: Wine CVS 2002-04-04. Test status: Compiles, no warnings. Tested with 16 bit apps: FreeAgent (newsreader), Solstice mail, nslookup, teraterm (telnet) (16 bit apps now call WS2_32 code!)

The following patch breaks compilation because there is a previous definition : Log message: Huw D M Davies <hdavies(a)codeweavers.com> Implement GetTextExtentPointI and add support for ETO_GLYPH_INDEX.
