Hello all, I am new to the wine scene and would like to try my hand at a little wine hacking. Are there any bugs out there that would be easy for a newbie to fix while letting me learn a bit about the inner workings of wine? I have read all the material about getting started developing, but I am just lacking a bit of direction on what to work on :) Thanks for your help, ryan

fix triggers crash

And without the patch above the error dosn't get triggered. This seems strange because the error seems to occur in x11drv.StretchBlt and ImageList_Merge dosn't call StretchBlt. To reproduce the crash start FreeSolitaire with the patch above applied, select a solitaire game and start dragging a card around and wine will crash. With --debugmsg +relay it takes sometimes longer to trigger the bug, just release the card I try dragging an other card (i never needed to release the second card yet, wine crashed before). I've attached the last 1000 lines of relay output, hope that helps. bye michael -- Michael Stefaniuc Tel.: +49-711-96437-199 System Administration Fax.: +49-711-96437-111 Red Hat GmbH Email: mstefani(a)redhat.de Hauptstaetterstr. 58 http://www.redhat.de/ D-70178 Stuttgart

SetActiveWindow problem
by bperkins＠netspace.org Nov. 27, 2001

Nov. 27, 2001

Sorry, I'm new to wine hacking, so bear with me. I was playing around a bit the other day trying to see if the tahni deskmate worked at all. I tried to run the installer (tahnisetup.exe available at tahni.com) It would run, and then crash with a stack overflow. I've attached the sequence in a backtrace that was repeated many times at the bottom. It's wine-20011108, BTW. Since I don't have the source to tahnisetup it made things a bit tricky to decipher. My guess was(is) that the program is trying to the window as active, which sends a message to the program. It sees that it's not active, so it again tries to set it as be active, which eventually causes a stack overflow. My awful hack was to just put a sanity counter in SetActiveWindow and return true after being called a certain number of times. This seems to work, as in it causes to program to get farther (it gets stuck on something else). Presumably one could check if it was being called recursively. I realize that this isn't really useful info, but I was curious to see if I was right about this, or if anyone had an insight. Am I right or did I just get lucky with the hack? 25246 0x0040266f (tahnisetup.exe..text+0x166f in E:\tahnisetup.exe) (ebp=437e6444) 25247 0x407c3a67 (WINPROC_wrapper+0x17 in libuser32.so) (ebp=437e6468) 25248 0x407c3af2 (WINPROC_CallWndProc+0x82(proc=0x4025b8, hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [winproc.c:173] in libuser32.so) (ebp=437e6498) 25249 0x407c95ca (CallWindowProcA+0x4a(func=0x4025b8, hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [winproc.c:2623] in libuser32.so) (ebp=437e64cc) 25250 0x4097b54c (FILEDLG_CallWindowProc+0x54(lfs=0x40400dbc, wMsg=0x6, wParam=0x0, lParam=0x10026) [filedlg.c:294] in libcomdlg32.so) (ebp=437e64f4) 25251 0x4097d944 (FileOpenDlgProc+0x78(hWnd=0x1002f, wMsg=0x6, wParam=0x0, lParam=0x10026) [filedlg.c:1440] in libcomdlg32.so) (ebp=437e651c) 25252 0x407c3a67 (WINPROC_wrapper+0x17 in libuser32.so) (ebp=437e6540) 25253 0x407c3af2 (WINPROC_CallWndProc+0x82(proc=0x4097d8cc, hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [winproc.c:173] in libuser32.so) (ebp=437e6570) 25254 0x407c91f4 (WINPROC_CallProc32WTo32A+0x80(func=0x4097d8cc, hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [winproc.c:2435] in libuser32.so) (ebp=437e6598) 25255 0x407c972b (CallWindowProcW+0xab(func=0x430c0984, hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [winproc.c:2675] in libuser32.so) (ebp=437e65cc) 25256 0x4079f744 (DefDlgProcW+0x48(hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [defdlg.c:389] in libuser32.so) (ebp=437e65f8) 25257 0x407c3a67 (WINPROC_wrapper+0x17 in libuser32.so) (ebp=437e661c) 25258 0x407c3af2 (WINPROC_CallWndProc+0x82(proc=0x4079f6fc, hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [winproc.c:173] in libuser32.so) (ebp=437e664c) 25259 0x407c9152 (WINPROC_CallProc32ATo32W+0x7e(func=0x4079f6fc, hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [winproc.c:2412] in libuser32.so) (ebp=437e6674) 25260 0x407c9647 (CallWindowProcA+0xc7(func=0x430c0259, hwnd=0x1002f, msg=0x6, wParam=0x0, lParam=0x10026) [winproc.c:2643] in libuser32.so) (ebp=437e66a8) 25261 0x4076957e (call_window_proc+0xf2(hwnd=0x1002f, msg=0x6, wparam=0x0, lparam=0x10026, unicode=0x0) [message.c:1146] in libuser32.so) (ebp=437e6704) 25262 0x4076a1af (SendMessageTimeoutA+0xdf(hwnd=0x1002f, msg=0x6, wparam=0x0, lparam=0x10026, flags=0x0, timeout=0xffffffff, res_ptr=0x437e6788) [message.c:1577] in libuser32.so) (ebp=437e6764) 25263 0x4076a317 (SendMessageA+0x37(hwnd=0x1002f, msg=0x6, wparam=0x0, lparam=0x10026) [message.c:1622] in libuser32.so) (ebp=437e6798) 25264 0x407c2e92 (WINPOS_SetActiveWindow+0x196(hWnd=0x10026, fMouse=0x0, fChangeFocus=0x1) [winpos.c:1282] in libuser32.so) (ebp=437e67f0) 25265 0x407c229a (SetForegroundWindow+0x7a(hwnd=0x10026) [winpos.c:781] in libuser32.so) (ebp=437e680c) -- "Only CmdrTaco can save us now" -- The Register Brian Perkins bperkins(a)netspace.org

winedbg error
by Dave Hawkes Nov. 26, 2001

Nov. 26, 2001

Hi all, I keep getting an assertion in winedbg, before I try and find out the cause does anyone know the possible reason for this? winedbg: types.c:573: DEBUG_CopyFieldList: Assertion 'dt->type == dt2->type && ((dt->type == DT_STRUCT) || (dt->type == DT_ENUM))' failed. It looks like its an issue with parsing the debug info, but the windows application debugs just fine with MS Developer Studio 6. Thanks, Dave Hawkes

ITypeInfo_fnGetContainingTypeLib
by lawson_whitney＠juno.com Nov. 25, 2001

Nov. 25, 2001

Good day! Anyone like to take a swat at this? I don't normally shy from a page fault, but frankly, ICOM confuses me. Anyway, maybe Ove can spot it in a second. If I have to do it it may take weeks. Backtrace attached. Wineconsole seems to be working nicely, as long as the resolution is good and high. I wanted to include a typelib trace, but that crashes at an earlier spot. I haven't really looked at that one yet; I can send it along if anyone is interested. At least Wine is starting to get its teeth into InstallSh**** and its confounded IKernel.exe.
