The conditions look very minimal, we should be fine with them. A check once a month should be fine. Just send the results to wine-devel(a)winehq.org. (There's some chance we'll ask you to switch to sending them somewhere else, but that will do initially.) For the moment just put the calysto.org link in the mail. Once it's clear the results are useful, somebody will link to calysto at least from our wiki. Say, whatever happened to Coverity's scans of Wine? I just logged in to the Wine results at http://scan.coverity.com, and the last scan seems to have been last July. Did they set up a new, private site for us? Paul V., do you know? - Dan -- Wine for Windows ISVs: http://kegel.com/wine/isv

Coverity status
by Paul Vriens 21 Jun '07

21 Jun '07

Hi, I've been in contact with Coverity. People currently listed as Wine contacts are: - Jan Zerebecki - Paul Vriens The main page is changed so it reflects the new scan site http://scan2.coverity.com:7479 and there has just been a new run! Coverity is very busy setting up some proper communication channels and some means for the contacts to do some kind of user administration (limited of course). Apart from that a lot of the current manual tasks will be automated (like the counters on the page where Wine is listed http://scan.coverity.com/rung1.html). Cheers, Paul.

But that whole function should probably be removed, dumping version info doesn't belong in winmm. -- Alexandre Julliard julliard(a)winehq.org

NULL ptr dereferences found with Calysto static checker
by Domagoj Babic 20 Jun '07

20 Jun '07

Hi, I've ran my static checker Calysto on Wine v0.9.35 and got 78 bug reports: makedep: 1 sfnt2fnt: 4 winebuild: 6 winedump: 2 winegcc: 5 libwine: 60 If you are interested in the reports, please: 1) read http://www.cs.ubc.ca/~babic/index_calysto_community.htm 2) if the conditions are acceptable, let me know where to send the reports. Kind regards, -- Domagoj Babic http://www.domagoj.info/ http://www.calysto.org/

On stuttering audio in quartz/DirectShow
by Alex Villacís Lasso 20 Jun '07

20 Jun '07

Upon checking the source code of dlls/quartz I found out about the method SetSyncSource defined in the IBaseFilter interface: dsoundrender.c:static HRESULT WINAPI DSoundRender_SetSyncSource(IBaseFilter * iface, IReferenceClock *pClock) filesource.c:static HRESULT WINAPI AsyncReader_SetSyncSource(IBaseFilter * iface, IReferenceClock *pClock) filtergraph.c:static HRESULT WINAPI MediaFilter_SetSyncSource(IMediaFilter *iface, IReferenceClock *pClock) parser.c:static HRESULT WINAPI Parser_SetSyncSource(IBaseFilter * iface, IReferenceClock *pClock) transform.c:static HRESULT WINAPI TransformFilter_SetSyncSource(IBaseFilter * iface, IReferenceClock *pClock) videorenderer.c:static HRESULT WINAPI VideoRenderer_SetSyncSource(IBaseFilter * iface, IReferenceClock *pClock) In particular, I see the following two things about sync sources: 1) I see no effort on part of filtergraph.c to add a sync source when simply asked to render a file 2) Even if it did, current implementation of videorenderer.c does nothing with its sync source So I have a couple of questions: 1) Am I right to assume that a sync source might be used to synchronize and (if necessary) drop frames at the videorenderer in order to maintain synchronization and avoid stuttering? 2) Could the sttutering really be solved by implementing the using and passing of a synchronization source (systemclock.c) in file rendering? If so, then the migration to DirectDraw would become just an optimization to increase the frame rate. Alex Villacís Lasso -- perl -e '$x=2.4;print sprintf("%.0f + %.0f = %.0f\n",$x,$x,$x+$x);'
