Nasty Evil Memory Fragmentation fix
by Gavriel State 10 Oct '01

10 Oct '01

We just spent about 3 days tracking down a very subtle memory fragmentation problem in an app we're working on. The problem: App allocates lots of little blocks, then a few large blocks, then lots of little blocks. Throughout this process, many blocks would be freed from all over the heap. Repeat ad infinitum. We ended up creating a new subheap every time one of these larger blocks came along. The new space from the subheap then went to the top of the freelist, so all the small allocations then filled it up until the next large block allocation. IE: We never got a chance to reuse freed blocks in older subheaps - at least not very well. This fix addresses the problem by pushing 'large' freed blocks to the end of the free list, leaving 'small' blocks at the front, to be found sooner. The size of 'large' vs 'small' is tunable. Despite the workaround, we're still not too pleased with the current heap allocator. It's quite slow, and still not as efficient as it could be. It would probably be worth the effort to integrate a new allocator - anyone know if there's a high-quality Wine-license- compatible allocator out there? -Gav -- Gavriel State, CEO TransGaming Technologies Inc. http://www.transgaming.com gav(a)transgaming.com --- heap.c Wed Sep 26 19:11:21 2001 +++ /home/gavriels/transgaming/wine/memory/heap.c Tue Oct 9 23:53:15 2001 @@ -59,6 +59,8 @@ #define QUIET 1 /* Suppress messages */ #define NOISY 0 /* Report all errors */ +#define FREE_BLOCK_INSERTION_THRESHOLD 4096 + #define HEAP_NB_FREE_LISTS 4 /* Number of free lists */ /* Max size of the blocks on the free lists */ @@ -229,11 +231,11 @@ /*********************************************************************** - * HEAP_InsertFreeBlock + * HEAP_InsertFreeBlockAtFront * - * Insert a free block into the free list. + * Insert a free block into the front of the free list. */ -static void HEAP_InsertFreeBlock( HEAP *heap, ARENA_FREE *pArena ) +static void HEAP_InsertFreeBlockAtFront( HEAP *heap, ARENA_FREE *pArena ) { FREE_LIST_ENTRY *pEntry = heap->freeList; while (pEntry->size < pArena->size) pEntry++; @@ -244,6 +246,31 @@ pEntry->arena.next = pArena; } +/*********************************************************************** + * HEAP_InsertFreeBlockAtEnd + * + * Insert a free block into the end of the free list. + */ +static void HEAP_InsertFreeBlockAtEnd( HEAP *heap, ARENA_FREE *pArena ) +{ + FREE_LIST_ENTRY *pEntry = heap->freeList; + + /* Determine which free list contains blocks of the appropriate size. */ + while (pEntry->size < pArena->size) pEntry++; + + /* But we want to put this block on the end of said appropriate free list. + * So instead, find the list for the next size up, knowing that they are + * all connected. */ + if (++pEntry == heap->freeList+HEAP_NB_FREE_LISTS) + pEntry = heap->freeList; + + pArena->size |= ARENA_FLAG_FREE; + pArena->next = &pEntry->arena; + pArena->prev = pEntry->arena.prev; + + pArena->next->prev = pArena; + pArena->prev->next = pArena; +} /*********************************************************************** * HEAP_FindSubHeap @@ -372,7 +399,11 @@ /* Last, insert the new block into the free list */ pFree->size = size - sizeof(*pFree); - HEAP_InsertFreeBlock( subheap->heap, pFree ); + + if ((pFree->size & ARENA_SIZE_MASK) > FREE_BLOCK_INSERTION_THRESHOLD) + HEAP_InsertFreeBlockAtEnd( subheap->heap, pFree ); + else + HEAP_InsertFreeBlockAtFront( subheap->heap, pFree ); }

Thanks for the hint, I'll try to reproduce it with an appropriate ulimit set. But right, an actual wineserver crash didn't happen in a while. Unfortunately I have some system instability currently, so many times the message was caused by a stale socket lying around after a solid lockup of my box. What tends to happen rather often though is that wineserver keeps running after I quit all windows/winelib apps and consumes 100% CPU. In some of such cases, it'll only die on SIGKILL, which also leaves a socket around. I agree that neither a system lockup nor a hanging wineserver should happen though :) Maybe there could be a wineserver.pid file in the same dir and only if the process identified therein doesn't exist anymore, the socket will be autoremoved? But after all it's not too big a problem, guess there are more important issues. -- Malte Starostik PGP: 1024D/D2F3C787 [C138 2121 FAF3 410A 1C2A 27CD 5431 7745 D2F3 C787]

The problem with this is that it creates a race condition and we may end up with two servers running in the same directory, which is bad. The error message should only happen when a previous server has crashed, which is a critical error (the server should never crash no matter what the app does). In that case you should also have a core file in the same directory as the socket, which you can use to debug and fix the crash. -- Alexandre Julliard julliard(a)winehq.com

using a webcam driver for windows
by Hrafnkell Eiríksson 09 Oct '01

09 Oct '01

Hi This might be a silly question, but would it be possible to use wine with a parallel port webcam driver and an windows application to show images to use a webcam in linux that only has windows suport? I'm thinking about how to get my Logitech QuickCam VC to work in linux :) I know that wine can to some extent access the parallel port in linux. I'm not very familiar with the inner workings of windows, but I guess the camera driver is something called .VxD? Would it be possible to let wine use that somehow? Or does wine not work at that low level? If it is possible to do this, is there something that a guy armed with a C compiler but almost no understanding of windows and wine internals can get working? Thanks Hrafnkell

Rendering problem in NetTerm
by Mike McCormack 09 Oct '01

09 Oct '01

Hi All, i'm trying to solve a comms problem in NetTerm http://www.securenetterm.com/ but i've run into another problem. The rendering in NetTerm fails almost completely. Its main window ends up with only the boarders drawn and will draw some toolbar buttons if i move the mouse over them. The following message appears repeatedly in the debug log: err:region:CombineRgn Invalid rgn=1096 i did a bit of tracing of the app and found that the region 1096 is created, used by a DC, destroyed, then used again. Is it possible that the reference count of the region is incremented when it is used in some way by a DC? A similar problem to the reference counting one Uwe Bonnes discovered (see message to this list on 16 Aug)?
