I love the idea. Could it be packaged with wine, or do you think it would be better off being a cousin of winetricks?

Tests question.

I am trying to get the tests to run before I submit a patch to shdocvw/webbrowser.c. My first attempts to get the tests to run. This morning I did cd /home/davea/winebld/wine git fetch; git rebase origin # make sure you're up to date ./configure && make depend && make # rebuild the tree rm -rf ~/.wine # be sure to test in a clean WINEPREFIX sudo cp /home/downloads/wine_gecko-1.0.0-x86.cab /usr/local/share/wine/gecko sh ../apps/winetricks winxp mkdir /home/davea/.wine/drive_c/windows/system32/gecko/1.0.0/wine_gecko /bin/echo -n "Wine Gecko 1.0.0" >/home/davea/.wine/drive_c/windows/system32/gec ko/1.0.0/wine_gecko/VERSION cat /home/davea/.wine/drive_c/windows/system32/gecko/1.0.0/wine_gecko/VERSION make testclean make test and it failed on an init_d3d8 call. ../../../tools/runtest -q -P wine -M d3d8.dll -T ../../.. -p d3d8_test.exe.so visual.c && touch visual.ok err:wgl:opengl_error No OpenGL support compiled in. err:d3d_caps:WineD3D_CreateFakeGLContext Can't find a suitable iPixelFormat. err:d3d:InitAdapters Failed to get a gl context for default adapter err:d3d:WineDirect3DCreate Direct3D8 is not available without opengl visual.c:131: Tests skipped: could not create D3D8 visual.c:1312: Test failed: Could not initialize direct3d make[2]: *** [visual.ok] Error 1 make[2]: Leaving directory `/home/davea/winebld/wine/dlls/d3d8/tests' make[1]: *** [d3d8/tests/__test__] Error 2 make[1]: Leaving directory `/home/davea/winebld/wine/dlls' make: *** [dlls/__test__] Error 2 I note that d3d8/tests/visual.c does a win_skip() when the init_d3d3() fails.

This is what is causing the error.

Why not a skip() ? > Because it will cause your test to pass is not a good reason to put in a skip(). Fix the OpenGL error and this test should give proper results. James McKenzie

RFC: winediag script
by Roderick Colenbrander 02 Dec '09

02 Dec '09

Hi, Over the years I have assisted a lot of people setting up Wine. In a lot of cases Wine doesn't work well because of missing libraries, pulseaudio, misconfigured display drivers and so on. I have written a script called 'winediag' which attempts to scan a system for the most common problems. Right now it contains mostly display driver related checks and a few basic audio / printing checks. I hope people have suggestions for most tests e.g. network tests (/etc/hosts, samba), more thorough driver checks and son. What do you guys think about it so far? (BTW I'm not a shell guru, so I would love to get some positive feedback) Thanks, Roderick Colenbrander

Valgrind cleanup status
by Dan Kegel 02 Dec '09

02 Dec '09

The logs of valgrind errors at http://kegel.com/wine/valgrind/logs/ are showing a nice downward trend: date files errors nonleak errors 2009-10-23 84 2383 339 2009-10-26 82 2344 319 2009-10-27 82 2318 294 2009-10-28 83 2325 294 2009-10-29 80 2279 253 2009-10-30 81 2304 280 2009-11-03 80 2612 301 2009-11-04 78 2290 276 2009-11-05 79 2295 268 2009-11-09 73 2215 254 2009-11-10 75 2266 296 2009-11-11 75 2236 263 2009-11-13 72 2264 234 2009-11-16 69 1724 222 2009-11-17 69 1711 221 2009-11-18 88 1736 253 2009-11-19 85 1696 247 2009-11-26 76 1628 168 2009-11-27 88 1797 302 2009-11-30 76 1779 288 2009-12-01 73 1723 230 The spike at 11-27 was when I started running with my heap tail corruption detection patch; those errors were present before, but not detected. Thanks to everyone who's been chipping away at these warnings. (Part of the decline has been knowing which suppressions to add, but that's ok, cleaner logs are good.) I'm mostly worried about nonleak errors for now, so I might be undercounting leak errors somewhat. As always, more help with these would be welcome. Some of the errors aren't that hard to deal with (but at the same time, some of them look easy but are subtle, so take care). - Dan

Silencing RtlNtStatusToDosErrorNoTeb() a bit
by Wolfram Sang 02 Dec '09

02 Dec '09

Hi, while debugging an application (Project One, available at [1]), I noticed that wine (today's git) throws a lot of these fixmes: fixme:ntdll:RtlNtStatusToDosErrorNoTeb no mapping for c0000109 Looking around, I found this page[2] stating that ERROR_MR_MID_NOT_FOUND is an expected return value for c0000109, so that the fixme is not needed here. I updated the if clause accordingly: diff --git a/dlls/ntdll/error.c b/dlls/ntdll/error.c index 9469f6f..e125163 100644 --- a/dlls/ntdll/error.c +++ b/dlls/ntdll/error.c @@ -68,7 +68,9 @@ ULONG WINAPI RtlNtStatusToDosErrorNoTeb( NTSTATUS status ) if (status < table->end) { DWORD ret = table->table[status - table->start]; - if (ret == ERROR_MR_MID_NOT_FOUND) FIXME( "no mapping for %08x\n", status ); + if (ret == ERROR_MR_MID_NOT_FOUND && + status != STATUS_MESSAGE_NOT_FOUND) + FIXME( "no mapping for %08x\n", status ); return ret; } table++; This solution has the advantage of being not very intrusive, but the disadvantage that it might be not nicely maintainable. Another &&-block has to be added for each other status found validly returning ERROR_MR_MID_NOT_FOUND. Another solution might be to define, let's say, ERROR_WINE_FIXME for all real fixmes and convert them to ERROR_MR_MID_NOT_FOUND. Something like (just a draft): #define ERROR_WINE_FIXME 0xffffffff DWORD ret = table->table[status - table->start]; if (ret == ERROR_WINE_FIXME) { FIXME( "no mapping for %08x\n", status ); ret = ERROR_MR_MID_NOT_FOUND; } return ret; [and lots of table entries changed] Well, this is pretty intrusive, but may be better distinguishing the different cases perhaps. Then again, this additional #define is polluting the ERROR_-namespace. I think I prefer the first version for now, perhaps there is no second status validly returning ERROR_MR_MID_NOT_FOUND? Any advice on how I should proceed? Thanks in advance, Wolfram [1] ftp://ftp.scs-trc.net/pub/c64/Tools/Graphics/Project1_V0.5.zip [2] http://support.microsoft.com/kb/113996
