Anyone planning on attending the Linux World Expo? I was going to be in the Bay area on the 12th anyway to tour Berkley so I think I'm going to extend my trip to make the show.

Bug in RegEnumValueA ?
by Massimo 03 Jul '02

03 Jul '02

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

Re: Fix for [bug 829] DIB_DirectDrawSurface_Blt same src./dest. surface = screen corruption
by Lionel Ulmer 03 Jul '02

The patch looks fine to me. There is just one comment opn these lines : > + if (SameSurface) > + { > + static BOOL WarnSurface = FALSE; > + if (!WarnSurface) > + { > + FIXME("\tSame source and destination could cause display problems\n"); > + WarnSurface = TRUE; > + } > + } Why did you add this ? 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. A part from these nitpicks, the patch looks fine and I will test it this evening on FalloutTactics to see if it fixes the screen corruption :-) Lionel -- Lionel Ulmer - http://www.bbrox.org/

Arts, DSound, and Media Player
by Jeremy Shaw 03 Jul '02

03 Jul '02

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.

Still getting this error
by Steven Edwards 03 Jul '02

03 Jul '02

With the last release I can build and use wine but with the current CVS I still get the following errors. Warning: loading builtin gdi32.dll, but native version already present. Expect trouble. Warning: loading builtin user32.dll, but native version already present. Expect trouble. wine: Unhandled exception, starting debugger... I am still not able to track down the patch that causes this. I have a clean WINE with no windows on any of my drives in my slackware box. Thanks Steven __________________________________________________ Do You Yahoo!?

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
by Lionel Ulmer 02 Jul '02

> 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).
