Just so people don't think the code has fallen off of the face of the planet ;-) Currently I'm working on two things with the wine jack driver , one of which needs to be complete before I submit the patch, the other can wait until some ongoing jack support is complete. 1. The driver currently closes and opens jack connections synchronously with wodOpen and wodClose. The problem is that jack doesn't actually close the clients right away, sometimes it can take many seconds for this to occur. Apparently this is a known jack bug but I'm also wondering if this is a problem in wines pthread implementation of conditions(there is no support for them right now). Either way I've implemented a workaround that basically consists of opening jack connections and marking them as in-use or available as apps open or close audio devices. This behavior can be enabled/disabled via a define in the driver. This isn't complete yet but it should be soon and would prevent the lockups and delays that currently make things a pain. 2. I don't know of an easy way to do resampling so the input audio matches the sample rate that jack expects. What I want is to be able to do something along the lines of: set_sample_rates(input_rate, jack_output_rate); set_resample_algorithm(x); /* pick a reasonable algorithm based on the current cpu and latency requirements */ And then in the callback routine something like: resample(audio_data_in, *audio_data_out); I haven't found anything even close to this simple as of yet, if anyone has any suggestions feel free to mail me about them. There is someone on the jack mailing list working on a resampling library that is supposed to be easy to use and flexable. Either way, this isn't critical although your music sounds funny if your sample rates don't line up very well ;-) Otherwise I'm also looking into a crash with using the jack driver and directsound that might be due to the client process and memory allocation. After working on the arts driver I realized that the future of audio servers really is callback based. It is quite frustrating to see so little use of jack and so much use of poor solutions like direct hardware drivers(alsa/oss) or high latency servers like artsd. No offense intended to people that work on or use either of those audio solutions, it just doesn't make sense when you want to have multiple apps outputting audio at the same time or if you need low latency(high end audio, games?, etc). I'll see what I can do to get things cleaned up and a patch submitted in the next week, conditional of course upon Alexandre accepting jack support into wine. At least now I have someone other than myself with an interest in using jack and wine together ;-) Thanks, Chris > > From: "Kjetil S.

Re: using native regedit
by Jeff Smith 23 Oct '02

23 Oct '02

I did some testing and found that *\\whatever.exe does not work, while *whatever.exe does. In case anyone thinks to themselves, "but that could cause problems for xwhatever.exe!", I tested further and found that it only affects programs with the name whatever.exe and not those such as xwhatever.exe. -- Jeff S. >We could add this to show different behaviours : > >; you can specify applications too >; This one will apply for all notepad.exe >;"*\\notepad.exe" = "native, builtin" >; This one will apply only for a particular file >;"C:\\regedit.exe" = "native, builtin" > >Is everyone ok ? _________________________________________________________________ Get faster connections -- switch to MSN Internet Access! http://resourcecenter.msn.com/access/plans/default.asp

Fixing OLE_GetFormatW
by Medland, Bill 23 Oct '02

23 Oct '02

I am just about to fix OLE_GetFormatW. (As far as I can see it can't have worked since rev 1.1). Before correcting the minor error I want to check something. Can anyone with access to NT answer this for me? If you pass a format string to GetDateFormatW that contains time-formatting characters I presume it just throws them away. Similarly if you pass a format string to GetTimeFormatW that contains date-formatting characters I presume it throws them away. Bill

fairly old wine regression: no$gmb no longer works
by Jonathan Gevaryahu 23 Oct '02

23 Oct '02

In wine builds from early? last year until January 29th, 2002, no$gmb (Nocash gameboy emulator) worked reasonably in wine (yes it would crash if you did 'animate trace' for too long, but that's a seperate issue). the commit which broke it was to wine/dlls/comctl32/status.c, on January 29th at 11:54 am. However, the fix that was done to status.c seems to be valid (later fixes to status.c do the same as what the fix did, I believe), so I suspect that the bug stems from some other issue which causes it to need the incorrect behavior in status.c in order to work. (personally I think it was something done during January that makes it need the incorrect status.c behavior, but I'm probably wrong) The nocash website is http://www.work.de/nocash/ or http://nocash.work.de/ Jonathan Gevaryahu

Bug tracked down in mci.c
by Erland Lewin 23 Oct '02

23 Oct '02

Hello, I just got the latest wine from cvs, and it crashed when I tried to run Half Life. The problem turned out to be in mci.c, in the mciSendStringA function. The variable lpCmd is set to point into the (in my case mciavi) driver's command table, at the word "open". However, towards the end of the mciSendStringA function, there is the following code: if (strcmp(verb, "open") == 0) { if ((dwRet = MCI_FinishOpen(wmd, (LPMCI_OPEN_PARMSA)data, dwFlags))) MCI_UnLoadMciDriver(iData, wmd); /* FIXME: notification is not properly shared across two opens */ } else { dwRet = MCI_SendCommand(wmd->wDeviceID, MCI_GetMessage(lpCmd), dwFlags, (DWORD)data, TRUE); } TRACE("=> 1/ %lx (%s)\n", dwRet, lpstrRet); dwRet = MCI_HandleReturnValues(iData, dwRet, wmd, lpCmd, data, lpstrRet, uRetLen); The problem is that MCI_UnLoadMciDriver is called, which causes the driver to be removed from memory, which means that lpCmd points to invalid memory. When MCI_HandleReturnValues then tries to use its lpCmd parameter, a segmentation fault will occur, becuase it tries to read from unmapped memory. I did a quick hack to work around the problem (lpCmd = strdup( lpCmd )) before the MCI_FinishOpen. I'd appreciate it if someone else could add a better permanent fix... Thanks for the good work on Wine!

It work eventhough it is a little kludgy. Oh well, it will do for now. Now I just have to properly fix all compile error instead of just kludging them...

wine not detecting wine printers
by Dan Fer 23 Oct '02

Has anyone tried using cups under Wine in any of the latest builds? I tried to builds from this month and none detect any printer. Is there a patch? Anything I could use to fix it? _________________________________________________________________ MSN. Más Útil Cada Día http://www.msn.es/intmap/
