You should simply do an open and check errno to find out what went wrong. Also there's no point in having a DRIVE_NO_MEDIA flag since this is a temporary condition. For the case of open succeeding with no floppy drive, I think you could handle it by checking if the subsequent read() fails. -- Alexandre Julliard julliard(a)winehq.com

And this is bad as memcpy does NOT handle overlapping memory zones. Moreover, you only have the 'descending' copy order in that case and not both cases. What I had in mind in my comments to your patch was something like that : if (src != iface) Do the standard memcpy code path else if source_Y > dest_Y do the ascending memmove copy else do the descending memmove copy This way you did not hurt the common case (ie Blt from two different surfaces). Now I agree that even in the same surface case, one could add some checks to see if the rectangles overlap or not, but I do not know if it would be worth the pain as memmove should not be THAT slower than memcpy.

GRand Prix Legends network code
by Christoph Frick July 5, 2002

July 5, 2002

Hi! I did some debugging, to find out why the game Grand Prix Legends did not work as network client/server. The problem: Its only possible to connect to servers/let clients connect from the local network. Solution: The game set (WS_)SO_DONTROUTE on the socket - and of course this works perfect under unix - but i never had problems while i played this game under windows so this is either not set, when the game runs under windows - or it has no effect within windows. Also the game like to bind the socket for the client connection a second time, when the first connection failed or was canceled. This does not work (addr. in use) - so a (WS_)SO_REUSEADDR would have been needed. Could please someone with a deeper insight in the world of windows direct me to some docu/specs or what ever to get informations about the winsock stuff? The link in the header of the dlls/winsock/socket.c is not valid. I even dont know what winsock version is the current one (1.1,2.0,???). Help is appreciated! Thanx alot! CU!

Running half-life turns X display into garbage
by Joshua Thielen July 4, 2002

July 4, 2002

Hello, When I run half-life, the X display gets totally corrupted and the only way to restore is to restart the X server. I'm using an NVidia G-force 3 video card running at 1024x768 with 16-bit color. I have already run a few traces, but since I have no idea at what point the display gets corrupted, it's kind of hard to debug. Has anyone encountered this problem yet? Are there any specific functions or channels I should be looking at in the trace? Thanks, Josh Thielen __________________________________________________ Do You Yahoo!? Sign up for SBC Yahoo!

2 quick things on the Cygwin/Mingw port
by Steven Edwards July 3, 2002

July 3, 2002

Hola 1. This is simple but as you guys know I have this lysdexic thing when it comes to configure. Libwine needs to import certain functions from the c library to compile, at present it is hard coded for -lmsvcrt. This needs to be changes to import -lcygwin if configure detects a cygwin host/target. I know its simple we just need to have the check in configure that sets CLIBRARY=(lmsvcrt or lcygwin) then Makefile.in in libwine needs to be changed like this: libwine.dll: $(OBJS) $(DLLWRAP) $(DLLWRAPFLAGS) --export-all --implib libwine.a -o libwine.dll $(OBJS) -lmsvcrt to libwine.dll: $(OBJS) $(DLLWRAP) $(DLLWRAPFLAGS) --export-all --implib libwine.a -o libwine.dll $(OBJS) $(CLIBRARY) 2. I was able to get Wineserver.exe to compile under cygwin when I stubbed getthreadcontext and setthreadcontext. Kernel32.dll implements these to functions so on the Mingw or Cygwin port can I import it for these needed functions? Thanks and have a good 4th Steven __________________________________________________ Do You Yahoo!? Yahoo! - Official partner of 2002 FIFA World Cup http://fifaworldcup.yahoo.com

Re: Fix for [bug 829] DIB_DirectDrawSurface_Blt same src./dest. surface = screen corruption

If you verified your patch and it's working, why add additionnal debug informations that will only confuse people :-) ? Moreover, I do not know the performance hit between a 'memcpy' and a 'memmove', but well, one could have put the old code in a if (!SameSurface) to have the fastest path available to the most common case.

Arts, DSound, and Media Player
by Jeremy Shaw July 3, 2002

July 3, 2002

Hello, I am trying to get media player to work with the winearts audio driver. I compiled the latest source from CVS, added Drivers="winearts.drv" to the config file, and installed media player. When I try to play a file (like an mp3), I do not get any audio. If I watch the elapse time, it will increment normally for a few seconds and then start playing super fast. Also when it starts playing super-fast I get the following error a bunch of times: fixme:dsound:DSOUND_MixOne problem with underrun detection (mixlen=17640 < primary_done=49392) At this point in time I know very little about what is wrong. Do you guys (we are all guys ???) think it is a problem with the wine source, my build of KDE, or just some messed up config files. Or perhaps I just installed too many native DLLs trying to make media player work? I will keep hacking away, but any guidance will be highly valued. I have not gotten ever gotten sound using the winearts driver, but so far I have only tried media player. Thanks in advance, Jeremy Shaw.

Do you mean that the roman (English) font is ugly (since I have no idea whether the Chinese characters look ok maybe you let me know how they look)? You only have two fonts installed (see the above fragment from the log), so the english text has to come from one of these fonts. What you may want to do is to install some fonts like Arial, Times New Roman etc. You could either copy these from a Windows installation (or add a line to the [FontDirs] section of config to point at an existing Windows partition font directory), or you can download a selection of the core Windows fonts from Microsoft's website.

Really great work! A couple of comments though: /* * Special case: NULL lpReturnedString with size > 0 * This causes an application error in win2k. Let's make wine better :) */ IMO it's not very good idea to make some tests succeed under Wine, which clearly crashes under win2k. That would play some bad role in the case of the back porting Wine code to Windows, since some code, internal to Wine, could rely on that forbidden API behaviour. I also have the following failures under win2k: Number of bytes read do not match FAIL: c:\result.ini does not match compare1.ini Number of bytes read do not match FAIL: c:\result.ini does not match compare2.ini -- Dmitry.

Re: Small 'let's prevent a crash' fix

July 2, 2002

> This does not fix the real problem (ie why does this DC not have a font even > if the application called a 'SelectObject' on it), but well, it cannot harm > to be more verbose and to prevent crashes if possible :-) OK, found the 'error' : the problem comes from the fact that I am using client-side fonts (aka XRender) : so the 'font' part of the physDev structure is always '0'. And that also means that we cannot use as is the glXUseXFont function. So basically, I need to implement it myself using 'GetGlyphOutline' (should not be that hard to do :-) ). Now my question : is 'GetGlyphOutline' always working even when not using client-side fonts ? If yes, I will completely remove the call to glXUseXFonts (I know, in that case, fonts displayed by OpenGL will be different by the one displayed by X, but well, ...) and always use the manual 'GetGlyphOutline' function. And I will try at the same time to remove all GLX calls from wgl.c and put them in special X11DRV escapes to have a real X11 free wgl.c file (ie for example, creating an OpenGL context would be a special escape for the X11DRV as it's basically something that is in GLX).

Re: heads up: wine 20020605 broken on FreeBSD, workaround included

July 2, 2002

[ I'm now also Cc:ing this to the Wine developers, thus the full-quote. In fact, all non-GLIBC platforms seem to be affected by this bug! ] Based on your pointer, I believe I found the problem. In aclocal.m4 we have: AC_DEFUN([WINE_CHECK_ERRNO], [AC_CACHE_CHECK([for reentrant libc: $1],[wine_cv_libc_r_$1], [AC_TRY_RUN([int myerrno = 0; char buf[256]; int *$1(){return &myerrno;} main(){connect(0,buf,255); exit(!myerrno);}], wine_cv_libc_r_$1=yes, wine_cv_libc_r_$1=no, wine_cv_libc_r_$1=yes)]) AS_IF([test "$wine_cv_libc_r_$1" = "yes"],[$2],[$3])]) which, in configure, becomes: int myerrno = 0; char buf256; int *__error(){return &myerrno;} main(){connect(0,buf,255); exit(!myerrno);} That is, instead of an array of 256 characters, we have one character, and the invocation of connect() is definitely incorrect. Could someone more familiar with autoconf please have a look at this?

Bug in RegEnumValueA ?
by Massimo July 2, 2002

July 2, 2002

Again investigating AutoCAD r14 app under wine, I found a bug that make app hang when some registry values are present. At first I've made a script that cleans up registry before launching AutoCAD,but this was only a way-around to the problem. Looking at relay output, I found a loop in calling RegEnumValueA : // @@@@ START OF LOOP BLOCK HERE......... :Call advapi32.dll.RegEnumValueA (000000cc,00000001,40486844,404868ec,00000000,404868f4,41e62020, 404868fc) ret=008a3850 :Call ntdll.dll.NtEnumerateValueKey (000000cc,00000001,00000001,40486544,00000100,40486540) ret=406afb24 :Ret ntdll.dll.NtEnumerateValueKey() retval=00000000 ret=406afb24 :Call ntdll.dll.RtlUnicodeToMultiByteSize(4048653c,40486558 L"REGPATH\\\\HKEY_LOCAL_MACHINE\\Software\\Autodesk\\AutoCAD\\R1 4.0\\ACAD-2452448:80143967\\AutodeskApps\\LsObj",0000000e) ret=406afc03 :Ret ntdll.dll.RtlUnicodeToMultiByteSize() retval=00000000 ret=406afc03 :Call ntdll.dll.RtlUnicodeToMultiByteN (40486844,00000007,00000000,40486558,0000000e) ret=406afc24 :Ret ntdll.dll.RtlUnicodeToMultiByteN() retval=00000000 ret=406afc24 :Call ntdll.dll.RtlUnicodeToMultiByteSize(40486538,40486566 L"\\\\HKEY_LOCAL_MACHINE\\Software\\Autodesk\\AutoCAD\\R14.0\\AC AD-2452448:80143967\\AutodeskApps\\LsObj",000000bc) ret=406afc77 :Ret ntdll.dll.RtlUnicodeToMultiByteSize() retval=00000000 ret=406afc77 :Call ntdll.dll.RtlNtStatusToDosError(80000005) <--ERROR HERE ! ret=406afd5d :Ret ntdll.dll.RtlNtStatusToDosError() retval=000000ea ret=406afd5d :Ret advapi32.dll.RegEnumValueA() retval=000000ea ret=008a3850 <-- MORE DATA AVAILABLE RETURN (AUTOCAD KEEPS TRYING TO GET DATA) // @@@@ END OF LOOP BLOCK HERE Here RegEnumValueA returns an error of invalid buffer; Looking into code it seems to me that the NtEnumerateValueKey() used to find the largest name and value sizes of keys to be enumerated returns a wrong size; next use for reading the key gives an arror of buffer overflow, being it allocated with wrong (too small) size. AutoCAD keeps trying to get the keys/values, in and endless loop. Looking more with some debug print statements, it appears that Autocad allocates 4 bytes of buffer for the value, but RegEnumValueA needs much more, 94 in this case, giving an Out-Of-Buffer error back. It seems to me that the 94 bytes are for the name of the key, not for the value.... Regards Max

Are there any patches in waiting to disable the use of ALSA in the configure script ... or is this not needed?
