How did you guess I wouldn't like it? ;-) Actually I think it's a neat hack, but it doesn't belong in the server at all. You should be able to do the same thing as a client-side process using the Win32 debugging API. It could be either a stand-alone Winelib app, or a special mode inside winedbg so that you can reuse some of the code in there. -- Alexandre Julliard julliard(a)winehq.com

Small Fixes

Hi, I had some problems with application Super Memo 8.0 . It is an old 16-bit app ( hard for debugging :-) ) written in Borland Delphi (I guess). I wrote a patch and posted to wine-patches two months ago ,but that patch was rejected :-( . Now I have much simpler and I think correct patch solving the problem. --- windows/painting.c_or Wed Mar 28 16:39:17 2001 +++ windows/painting.c Sat May 5 14:19:43 2001 @@ -1710,7 +1710,7 @@ { /* send palette change notification */ HWND hWnd = WindowFromDC( hDC ); - if (hWnd) SendMessageA( HWND_BROADCAST, WM_PALETTECHANGED, hWnd, 0L); + if (hWnd) PostMessageA( HWND_BROADCAST, WM_PALETTECHANGED, hWnd, 0L); } return realized; } There is another bug.

Is the DECIMAL variant type too long ?
by gerard patel May 10, 2001

May 10, 2001

After the following patch : ChangeSet ID: 989259340138108821120113 CVSROOT: /opt/cvs-commit Module name: wine Changes by: julliard(a)wine2. 01/05/07 14:15:40 Modified files: include : oleauto.h wtypes.h include/wine : obj_base.h obj_oleaut.h Log message: Francois Gouget <fgouget(a)codeweavers.com> Added support for the DECIMAL type.

Borland Builder 4 crashes while starting :-/ Tracing the crash shows that it hangs immediately after the *first* variant Api access : Call oleaut32.VariantCopyInd(405869b0,40586974) ret=405b2e6b tid=08065a10 trace:ole:VariantCopyInd (0x405869b0, 0x40586974) trace:ole:VariantCopy (0x405869b0, 0x40586974) trace:ole:VariantClear (0x405869b0) Ret oleaut32.VariantCopyInd() retval=00000000 ret=405b2e6b tid=08065a10 Call oleaut32.VariantChangeTypeEx(40586968,405869b0,00000400,00000000,00000003) ret=405b301c tid=08065a10 trace:ole:VariantInit (0x4058685c),stub trace:ole:VariantChangeTypeEx (0x40586968, 0x405869b0 (11), 1024, 0, 3),stub trace:ole:VariantClear (0x40586968) trace:ole:VarI4FromBool ( -1, 0x40586970 ), stub trace:ole:VariantClear (0x4058685c) Ret oleaut32.VariantChangeTypeEx() retval=00000000 ret=405b301c tid=08065a10 err:seh:EXC_DefaultHandling Exception frame is not in stack limits => unable to dispatch exception. I have changed the trace slightly, the 11 listed for the VariantChangeTypeEx shows that the original type is a boolean. The call is trying to change a boolean (11) into an integer (3). The changes in include/wtypes.h are the important ones. Replacing the new DECIMAL type by typedef struct tagDEC { BYTE aa[2]; } DECIMAL; get rid of the crash. If I make the byte array 16 bytes long, same crash as the current Wine behaviour. If I make it 10 bytes long, access violation. If I make it 8 bytes long, it works too. Could the DECIMAL type be a pointer to the real data ?? Gerard

Stupid winedbg question
by Francois Gouget May 10, 2001

May 10, 2001

This is probably a stupid question but I did not find the answer in the doc (Wine Developper's Guide). How do I copy-paste something from winedbg? A backtrace for instance. Or how do I copy/paste anything to/from any console application for that matter. -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ Linux: It is now safe to turn on your computer.

Stupid autoconf question

Is this form more convenient for final submission, or should I include the changes to those files?

Well, there are tons of places where we will sleep inside a critical section, so it could potentially burn a lot of CPU. That doesn't necessarily make it slower, but it would probably impact other applications more. As usual, the only way to tell is to do benchmarks. -- Alexandre Julliard julliard(a)winehq.com

You forgot to remove redundant ' around %s in the traces when output is made by debugstr_a or debugstr_w. Actually you removed some of them, but not all.

Cutting and pasting in winedbg's xterm only works for me if i hold the shift key down when doing it. Dunno why. i've got more serious problems with winedbg... when exceptions are thrown on critical sections, winedbg starts, but then itself gets stuck on _the same_ critical section. Happens all the time with netscape... i've applied Marcus's patch and i'll see if that reduces the frequency of failures, but it probably won't help winedbg's problems.

Hi, Gamespy has an article regarding whether Games should be ported to Linux or emulated using WINE.
