Hello, capserve.exe is part of Adobe Acrobat 5's PaperCapture plugin. Runnning "wine capserve.exe" I get an error saying "Insufficient memory to perform operation" (although all runs fine under Windows). It seems that several calls to kernel32.VirtualAlloc(), ntdll.NtAllocateVirtualMemory() and related functions are executed right before the error message is issued. See the log-output below, with WINEDEBUG=+all. Could there be a problem with allocating virtual memory in Wine? Maybe the issue discussed under http://www.winehq.com/hypermail/wine-de...

...hat Guy''s version of mmap (for Unix) contains some string-like methods that let you access pieces of the view like a string. Patrick and I came up with this (which requires the latest windows-pr in cvs so that we can use a more flexible version of memcpy, as well as some constants for VirtualAlloc): def [](offset, length) buf = 0.chr * length memcpy(buf, @address + offset, length) buf end def []=(offset, length, string) memcpy(@address + offset, string, string.length) end This works as is but Ara also mentioned that some methods, such as MMap#[]=, will autoexpand the al...

Hi all, Looking at the IO.readlines source in io.c, it looks to me like they grab 8k chunks, split on the input record separator, and buffer accordingly. Since it looks like ReadFileScatter() does some of that work automatically (in page file sized chunks), I thought I''d give it a try. Here''s what I''ve got, but it doesn''t work. I have an incorrect parameter

...hing left before I want to release this (as 0.4.0) is to get NO_BUFFERING to work. Unfortunately, I can''t get it to work. Park, I looked at that site you sent (and borrowed some code from it), but I don''t see anything special happening for NO_BUFFERING. I thought it required VirtualAlloc() but I''m not sure. If anyone has any ideas on that, please let me know. Thanks. Regards, Dan

Hi I have a Problem with wine. I have one Program, that allogaces many small pieces with "malloc()" in the memory. "many" means over 2 Mio, "small" means "from 8 to 128 bytes" in size. Running this Program on Windows gives me ~300MB Memory Usage (according to one of the values in the Tast manager). In Linux, "top" shows me a physical Usage of

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

...d running a +relay,+seh,+tid trace (which was 253M big) and there were several trace:seh lines, the first being code c0000005 (access violation) after a call of user32.SetDeskWallPaper but it seems that was handled, and later there was a code c000013a after a load of calls to ReadFile() and then to VirtualAlloc(). It seems NtAllocateVirtualMemory is returning an error. The last file it opened was Program Files/Bider/Speech Plus/Resource/Standard/SMExtern.rul which is less than 1M so I don't see what's up with that. Why should NtAllocateVirtualMemory fail on kernel 2.6 but not 2.4? I'm using...

Hi, It seems that the new 1.8 patch brings and old problem back. The problem is : It's impossible to target any world object without some "tricks" [1] not always usable. This problem occured the first time with the 1.5 patch. A lot of workarounds were given on the forum and, finally, the 2.6.12 kernel fixed the problem for a lot of people (like me). Now the problem comes back but

I've got a simple (32bit) windows application (compiled in Borland c++ builder): int *p; while(1) { p = new int[10000000]; //allocates 40 MB of memory } on Windows XP it crashes after 50 iterations (i.e. 2 GB allocated) but on wine it crashes after 30 iterations (1200 MB allocated) is it impossible to use 2gb of memory in wine? why only 1.2GB is available? I've got wine 0.9.13,

...ent additions .. (1) Allocating RWX memory is used by the JIT Emitter for code generation and execution. The JIT software is now platform independent in this regard by using the new sys::Memory::AllocateRWX function. This function has been implemented to use variants of mmap on Unix platforms and VirtualAlloc on Win32. (2) The functions in "FileUtilities.h" for checking magic numbers and determining the type of a function have been added to the Path class. There are three new methods: has_magic_number, is_bytecode_file, and is_archive. These have been implemented as "generic Unix"...

...er per-thread information) on a global page all by themselves, and remap that virtual page for every thread. Then I could simply dereference the globals. On Unix I think I can do this playing games with mmap(), but I'm not sure how to do this on Windows. I played around a little with the VirtualAlloc function, but it doesn't look like it does what I need. Almost as good would be to add a level of indirection, have a global pointer to where the page is to be mapped, and just map it in the same place in every thread. Another possibility, and I'm not sure how to do this in LLVM, would...
