svchost Patch Question
by Roy Shea 13 Nov '07

13 Nov '07

Howdy, I'm looking for advice on how to clean up the implementation of svchost. The latest version is available at: http://www.winehq.org/pipermail/wine-patches/2007-November/046467.html If the stopper for this patch is the lack of a DLL using it, I can resend svchost later this week when I have a stub implementation of BITS using svchost ready. Thanks for any pointers! -Roy

xrun handling in winealsa.drv
by Timofei V. Bondarenko 13 Nov '07

13 Nov '07

Hi. I've noticed the winealsa does not handle alsa XRUNs. In the case of XRUN application hangs. That's happened because return value of snd_pcm_avail_update() is not checked. For example: wavein.c 175 DWORD bytes; 180 /* read all the fragments accumulated so far */ 181 frames = snd_pcm_avail_update(wwi->pcm); 182 bytes = snd_pcm_frames_to_bytes(wwi->pcm, frames); waveout.c 476 DWORD availInQ; 479 availInQ = snd_pcm_avail_update(wwo->pcm); 482 if (availInQ > 0) { The snd_pcm_avail_update() returns a _signed_ type and it really does return negative number -EPIPE in the case of XRUN. More over, any return value of less than period_size may indicate XRUN state too. The snd_pcm_state() may help then. Th dsoutput.c and dscapture.c do exactly the same wrong thigs. BTW, using DWORD type causes problems. Following fragment is from wavein.c too: 177 DWORD read; 181 frames = snd_pcm_avail_update(wwi->pcm); 182 bytes = snd_pcm_frames_to_bytes(wwi->pcm, frames); 193 read = wwi->read(wwi->pcm, lpWaveHdr->lpData + 194 bytesRead = snd_pcm_frames_to_bytes(wwi->pcm, 197 if (bytesRead != (DWORD) -1) This is obviously will not work as expected. I hope someone will fix these issues :) Regards, Tim.

Grumble. Lost the Valgrind magic.
by Dan Kegel 13 Nov '07

13 Nov '07

I had to reinstall my main valgrind testing machine (I foolishly ran the vmware server install script, and it nuked my wireless), and since then, valgrind isn't giving me stack traces. I guess something's wrong in my recipe, but I'm not sure what, the vg-3.2.3 patch is being applied. Sigh. Is anybody else having luck building a valgrind that gives good stack traces for wine?

Too many WM_MOUSEACTIVATE
by Peter Åstrand 12 Nov '07

12 Nov '07

I have lot's of problems with WM_MOUSEACTIVATE messages in "Magna Cura". The effekt is that certain popup dialog doesn't work: After selecting something, say a date, the whole "form" is cleared. After much debugging, I've found out that WM_MOUSEACTIVATE is the problem. If I explicitly stop WM_MOUSEACTIVATE from propagating from dialogs to parents, then things works OK. I do this by addding: case WM_MOUSEACTIVATE: return MA_ACTIVATE; in DefDlgProc{A,W}. I wonder how many things that will brake with a change like this.... Just a long shot, but has anyone else seen anything similiar to this? (It turns out that there are multiple differences compared to Windows; one with two many messages generated when the popup is created, another with too few messages when changing tab in a SysTabControl32 (but zero messages works fine as well.)

Problem with wine + Dreamweaver + VNC
by Francisco José Gallego Durán 12 Nov '07

12 Nov '07

Hello, I am trying to run Dreamweaver.exe and Photoshop.exe in a remote gnome-session through vnc4server. When I try to run it I get the following message: Xlib: extension "XFree86-DRI" missing on display ": 3.0". X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 148 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x24 Serial number of failed request: 11 Current serial number in output stream: 12 Might it be a kind of a bug? I am running wine 0.9.49, Debian etch with latest updates, and vnc4server. Thank you for your help. Francisco Gallego.

Re: widl [2/9]: Add an option to use Wine exception handlers.

Dan Hipschman <dsh(a)linux.ucla.edu> writes: > This patch adds a --wine-seh option to widl to use Wine's SEH instead of > the Windows one. This should not be a widl option. widl should generate a single version of the C code that works on all compilers, using appropriate macros and #ifdefs. Also you shouldn't use the wine/exception.h macros, since you are generating the code you can output the code directly, in a much more straightforward way than the convoluted __TRY macros. -- Alexandre Julliard julliard(a)winehq.org

How can we handle undcomented shell functionsAW, that MS declared now (WSTR version only)
by Detlef Riekenberg 12 Nov '07

12 Nov '07

Hi There are a some undocumented Functions in shell32, which have one entrypoint that use STR in win9x, but WSTR in NT: - dlls/shell32/undocshell.h - http://www.geocities.com/SiliconValley/4942/paths.html Some of them are now declared without A/W suffix (include/shobj.h from SDK 2003), but since win9x is no longer supported by MS, it's only for the Wide version. Examples: PathProcessCommend, PathResolve, PathQualify Question for include/shlobj.h: What is the correct way to declare such functions? In undocshell.h, we use functionAW with LPVOID for the first two, but for PathQualify, we use: // BOOL WINAPI PathQualifyA(LPCSTR path); BOOL WINAPI PathQualifyW(LPCWSTR path); #define PathQualify WINELIB_NAME_AW(PathQualify) BOOL WINAPI PathQualifyAW(LPCVOID path); // And PathResolve in exported by name (see shell32.spec) ############################################################# Next question for shell32.spec: Are we fixed to "ptr" for such functions? ("str", "wstr" and "long" are all used and need to be fixed) Is it possible / useful to add support for "awstr" (or a similar name)? What about support for UNICODE-Strings ("ustr")? -- By by ...

Re: cmdlgtst: Rename to dialogtest

IMHO it's better to remove programs/cmdlgtst altogether, it doesn't really test anything, and this is not a place for tests anyway. -- Dmitry.
