-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Anyone saw the article in June's Dr. Dobb's Journal, July 95 titled "Finding Binary Clones with Opstrings & Function Digests: Part I" by Andrew Schulman http://www.undoc.com Although just the first article, It already shows promise from wine's perspective. Generating hashes on the functions in the DLL's & EXE's while taking into consideration not to be fooled by the pointer diffs because of different positions in the binaries, Huge potential to find similar functions in all dll's instead of recoding them all. According to the article something Windows suffers from quite a bit...

There is no much point in that macro either, do that check directly instead and get rid of hhctrl.h completely. -- Dmitry.

Bug in native user32

by Jacek Caban

Hello. Fixing MSHTML tests I found a bug in Windows. In tests I passed const WNDCLASSEX, to RegisterClassEx what should work as its declaration is: ATOM WINAPI RegisterClassExW(const WNDCLASSEXW *); Changing passed WNDCLASS to nonconst makes it works. I wrote small tests (attached) showing that if hInstance of WNDCLASSEX is NULL, RegisterClassEx sets it to GetModuleHandle(NULL). It, of course, couses segmentation fault in case CMASSWNDEX is const. This problem seams to happen on XP, NT 4, 2k and 2k3. So the question is if we should clone this bug? Some applications may expect it, but other may crash. They will crash on Windows anyway... Or we should mark test as todo_wine and change it if we found application that depend on it?

Re: [AppDB] fix situation when AppDB is not at DocumentRoot (patch 1 of 3) (gah! resend)

by Chris Morgan

I ran into the same issue and was in the process of trying to fix it up. Maybe this is a better approach because it doesn't require any user intervention? The idea was to pass the relative path through that function to get the full local path. I can attach the rest of the patch if you'd like but it isn't in a finished state.

Re: ALSA: Call snd_pcm_drain instead of a buggy homegrown version

by Vitaliy Margolen

Isn't WODM_RESET should stop playback/recording immediately? In which case shouldn't we use snd_pcm_drop instead? I'm guessing here. I have that loop disabled here for some time now. And I can't hear any artifacts. PS: If we drop that loop we should remove all associated stuff as well.

Exception Handling with a "bad" ESP

by Glenn Wurster

I've been doing some debugging of the exception handler and have come across a problem for which I'm not sure what the best solution is. It involves an application using the ESP for something other than the stack. The current DIB code uses protection to detect when the application modifies the DIB bits and respond accordingly. It does this by disabling read and/or write access to pages and then catching exceptions when they are thrown so that it can keep the X11 and windows versions of the DIB seporate but reflect changes appropriately (There may be other pieces of Wine which use similar tactics). The application I am debugging, however, uses the ESP as a counter/memory offset in it's updating of the DIB. While not the best selection of registers, the application relies on ESP not being used for anything else while the DIB updates take place (In Windows this assumption is true). A made-up example of assembly code is as follows: mov esp, [0x12345678] ; Save the ESP mov 0x128796, esp ; Set up ESP for the DIB modification mov 0, ebp loop: mov ebp, [sp + bp] ; Write out the byte to the DIB inc ebp sub esp, 0x10000 ; The high word is a counter jns loop mov [0x12345678], esp ; Restore the ESP Now, one of the first things our exception handler in signal_i386.c does is set up the stack layout to deliver the exception to the application (see the setup_exception function), but in this case ESP definately does not point to the stack (and the application never intended for an exception to occurr). It instead contains a counter in the high word, and a memory offset in the low word. Because of this, there is a double fault which happens and Wine actually Segfaults as opposed to breaking into the debugger. So, what I'm wondering is if anyone who has experiance with the exception handling code has any thoughts on how this problem can be fixed. If your interested in actual application code which does this, Alpha Centauri is what I found the initial problem with. You can download the demo at http://www.firaxis.com/downloads/Demo/smac_demo1_1.exe. The assembly code in the application which causes the crash is located starting at around offset 0x0060d954. As an interesting side-effect, if there are other applications which are using ESP in a "bad" manor, then we may be corrupting memory whenever we generate an exception within Wine. This issue would be very hard to track down, which makes me think that only exceptions which would normally be generated in Windows should cause Wine to modify the application stack. Comments? Suggestions? Glenn.
