Infinite loop with translation DLL
by Uwe Bonnes 10 Nov '09

10 Nov '09

Hello, around July 2009, I implemented a translation dll, allowing to run Win32 programms using ftd2xx.dll with Wine translating the calls to linux-libftd2xx. It was done while looking at dll/glu32. I was able to run mprog.exe (www.ftdichip.org) some time ago. Reapplying now, I hit an infinite loop with the first translated call. I short, ftd2xx.spec contains: @ stdcall FT_ListDevices(ptr ptr long) FTD2XX_FT_ListDevices and ftd2xx_main.c: extern FT_STATUS FT_ListDevices(PVOID, PVOID, DWORD); FT_STATUS WINAPI FTD2XX_FT_ListDevices( PVOID pArg1, PVOID pArg2, DWORD Flags ) { FT_STATUS res = FT_ListDevices(pArg1, pArg2, Flags); TRACE("res %s\n", res2string(res)); return res; } and dlls/ftd2xx/Makefile.in contains: EXTRALIBS = @FTD2XXLIBS@ with EXTRALIBS detected in configure.ac. MProig.exe calls FT_ListDevices(), which is resolves as FTD2XX_FT_ListDevices(). Then FTD2XX_FT_ListDevices() is entered and FT_ListDevices() resolves again to FTD2XX_FT_ListDevices(), resulting in an infinite loop. Can anybody help with the flaw in my implementation? Or did anything change in wine? The patches still linger on the mailing-list as "Stub implementation for ftd2xx.dll" Thanks -- Uwe Bonnes bon(a)elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ----------

You shouldn't be suspending/resuming threads directly like this. They should block on open operation. Vitaliy.

If they can be applied independently then numbering is (strictly speeking) not needed but it does show where you're going. I'm not sure if it's only me but I have a hard time keeping tracking of all the patches you sent and what (or not) to apply in what order. -- Cheers, Paul.

Well its been a few since I ran CPP Check and so I ran it today and got the following: New CPP Check Errors for the Wine Code: [/home/cahrendt/wine-git/dlls/comctl32/imagelist.c:1908]: (error) Uninitialized variable: bmi_buf [/home/cahrendt/wine-git/dlls/ntdll/server.c:802]: (error) Resource leak: fd [/home/cahrendt/wine-git/dlls/ntdll/server.c:882]: (error) Resource leak: fd_cwd [/home/cahrendt/wine-git/dlls/shell32/shellord.c:416]: (error) Uninitialized variable: szText [/home/cahrendt/wine-git/dlls/shell32/shellord.c:416]: (error) Uninitialized variable: szTitle [/home/cahrendt/wine-git/dlls/shell32/shellpath.c:1360]: (error) Uninitialized variable: InfoBuffer [/home/cahrendt/wine-git/dlls/winex11.drv/xfont.c:2963]: (possible error) Resource leak: fd [/home/cahrendt/wine-git/server/mapping.c:118]: (error) Uninitialized variable: page_size Chris

re: Question on using winedbg when program does not crash, just becomes unresponsive
by Dan Kegel 10 Nov '09

10 Nov '09

Susan asked: > [What can you do to get a backtrace of a hung app that won't hang when you run it in winedbg?] I ran into this last week and added a note to http://wiki.winehq.org/Backtraces "Alternately, instad of info process / attach, you can do 'bt all' to get backtraces of all threads in all running processes. This is handy when debugging hangs." That's not a very clear explanation, but what it means is: start winedbg without any app say 'bt all' in winedbg Voila, you now have backtraces for every process, including the hung one. It's your job to get that into a text file and remove the uninteresting ones...

The user32/win test crashes X on Intel cards

Hi, >Marcus got the same issue and he had an Intel card too Charles Davis wrote: >This happens on Mac OS X, too. Check out >http://xquartz.macosforge.org/trac/ticket/293 Charles forgot to mention that it affects NVidia on the Mac, which I did not explicitly write in the above bug report (the Mac people will have guessed it from the "early 2009 Mac mini" comment). More precisely SetWindowPos(hwnd, 0, -32769, -40000, -32769, -90000, SWP_NOMOVE); #if 0 SetWindowPos(hwnd, 0, 32768, 40000, 32768, 40000, SWP_NOMOVE); #endif SetWindowPos(hwnd, 0, -32769, -40000, -32769, -90000, SWP_NOSIZE); SetWindowPos(hwnd, 0, 32768, 40000, 32768, 40000, SWP_NOSIZE); is enough to let the tests succeed with Version: 2.3.3.2 (2.3.3) Build Info: X11server-480700~6 OS Version: Mac OS X 10.5.7 (9J61) This hints that the bug is in the X server, not the individual drivers?

Mostly useless. A lot of those VMware boxes are mine. They come in two flavors. Some of them (starting with esx-) are ESX VMs, ESX is VMware's data center product, which simply doesn't support sound. The others (starting with gvg-) are Server VMs, which do support sound. The reason I didn't configure sound on them is because I'm simply not interested in sound. I'll consider enabling sound, but to be honest I'm a bit put off by your aggressive tone. Anyway, the end result is that there will always be ESX VMs that can't run sound tests. Best regards, Ge.

Question on using winedbg when program does not crash, just becomes unresponsive
by Susan Cragin 09 Nov '09

09 Nov '09

There is some sort of memory leak in Dragon NaturallySpeaking that makes the program become unresponsive (but not crash) after some minutes of using the Dictation Box. I have tried winedbg, SetOnFirstBreak but the program never actually crashes. Without SOFB, of course, winedbg goes for the first unhandled exception, which is harmless. I can't start winedbg right before the program crashes, because I don't know when it will do so. It just sort of wears down. There is nothing I do to make it become unresponsive. Any ideas?
