Hi, I am little bit interested in Wine source code. There is one thing I don't understand. How does HeapAlloc() work? Is it the same behavior as Winapi HeapAlloc()? If so then I have to check NULL value after each calling of this function, don't I? I have found this code in Wine 0.9.57: In dlls/dbghelp/stabs.c function 'static int stabs_new_include(const char* file, unsigned long val)' line 1...

Thanks for the suggestion James, it reduces the commit by about ~900 MB (14,9 GB -> 14 GB). Unfortunately it does not solve the performance problem. The heap is global to the application and thread-safe, so every malloc/free locks it, which evidently doesn’t scale. We could manually create thread-local heaps, but I didn’t want to go there. Ultimately allocated blocks need to share ownership

Hi! I am not sure if this is a bug or not. I have the following non-sense C module exc_alloc.c: #include <windows.h> void *AllocMem() { HANDLE heap = GetProcessHeap(); void *p = HeapAlloc(heap, HEAP_GENERATE_EXCEPTIONS | HEAP_ZERO_MEMORY, 16*1024*1014*1024); return p; } If I execute the following commands clang -S -emit-llvm -o exc_alloc.ll exc_alloc.c llc -filetype=asm exc_alloc.ll clang -c exc_alloc.s then I get the error messages exc_alloc.s:11:31: error: invalid varian...

One problem with Wine has been that there were few serious open source win32 applications out there to test Wine with (ok, maybe my opinions are from 1997 :-) In any case, we have some great open source Win32 applications to test with. AbiWord is one. I just tried installing AbiWord 0.9 under the latest Codeweavers preview. The install worked -- but generated about a billion warnings of the

So, the backend should implement "__alloc" that does the same as "malloc" - or something subtly different from "malloc" - and on a Windows machine, how is it different from "HeapAlloc"? And "__write" that is same as UNIX "write", but different from "WriteFile" in Windows? And HOW do you expect the backend to implement these? By calling "malloc"/"HeapAlloc", "write"/"WriteFile"? This is what the C library...

...installing itself and a bunch of dll's into the windows\system directory. The client however, pops up a message box on startup claiming "Invalid picture". Which debugmsg options would be helpful in finding the problem? Most of the 200 lines before this with +relay are TlsGetValue, HeapAlloc, HeapFree, RtlEnterCriticalSection, and RtlLeaveCriticalSection. Nothing that looks particularly interesting.. Ian

How do I test janitorial task ReplaceMalloc for console.c? I finished replacing the Malloc() functions with HeapAlloc() functions and the corresponding Free() functions with HeapFree() functions, but how do I test if it works? Here is my modified console.c code from wine version 0.9.60 http://www.pastebin.com/f5307c42f

Hi Pavel, Right, my app also crashes in a different place under winedbg, although it crashes in the same winedbg place under gdb. I took a closer look at wine --winver nt40 --debugmsg +all. I found something interesting. If I search for queue_exception, I find that there is an exception raised before the LoadOEMCall, about 328klines in: 0806d398:Call
