TCP/IP networking and registry keys
by Alan Chandler March 6, 2001

March 6, 2001

I spent most of the weekend trying to get Grand Prix Legends GPL to work. I achieved my first goal of getting it to run in server mode. One of the things I needed to get the game to do, was to recognise that there where some interfaces it could talk TCP/IP out of. It took me some time to realise that under windows it was doing this by looking for the key [System\\CurrentControlSet\\Services\\Class\\NetTrans] and was then enumerating the keys under it to establish an IP address ie the following [System\\CurrentControlSet\\Services\\Class\\NetTrans\\0000] "IPAddress"="10.0.10.100" The thought occurred to me that maybe the tool the builds the registry during wine install could actually create these keys - since it is essentially a key part of the system (and other similar keys are also built in the same way). I don't think I have the skills to do it myself yet. Alan alan(a)chandlerfamily.org.uk http://www.chandler.u-net.com

New execution behavior
by Duane Clark Feb. 28, 2001

Feb. 28, 2001

Howdy, Here is a symptom that has crept into the recent version of wine. Since I know how to make things work, this is just a post in case someone is interested. When I recently updated to the Feb 24 CVS version (from the Feb 4 version), I suddenly had the symptom that I could only run one program at a time. In other words, I ran the program schedit (one I use regularly), and it came up and worked fine. But when I then tried to also run symed, it would not come up, but instead gave: err:ntdll:RtlpWaitForCriticalSection Critical section 0x400f9ad0 wait timed out, retrying (60 sec) fs=022f Where the address 0x400f9ad0 is in: disas 0x400f9ad0 0x400f9ad0 (peb_lock [rtl.c]): addb %al,0x0(%eax) 0x400f9ad2 (peb_lock+0x2 [rtl.c]): addb %al,0x0(%eax) 0x400f9ad4 (peb_lock+0x4 [rtl.c]): 0x400f9ad6 (peb_lock+0x6 [rtl.c]): 0x400f9ad8 (peb_lock+0x8 [rtl.c]): addb %al,0x0(%eax) 0x400f9ada (peb_lock+0xa [rtl.c]): addb %al,0x0(%eax) 0x400f9adc (peb_lock+0xc [rtl.c]): addb %al,0x0(%eax) 0x400f9ade (peb_lock+0xe [rtl.c]): addb %al,0x0(%eax) 0x400f9ae0 (peb_lock+0x10 [rtl.c]): cmpb $0,%al 0x400f9ae2 (peb_lock+0x12 [rtl.c]): addb %al,0x0(%eax) Wine-dbg> Trying a couple other programs showed that this affected all of them. In particular, one that is more readily available, Wordview97. For example, I could run one instance of wordview, but not a second. This is running wine along with a Win98 installation. It turns out the for some obscure reason I had the DLLs exactly as in the sample config file, except that I had: "DefaultLoadOrder" = "builtin, native, so" Putting it the (presumably) right way fixed things (except a wordview font problem): "DefaultLoadOrder" = "native, builtin, so" Here is info on the the loading of DLLs. The only differences I see with native first is with ole32 being native instead of builtin, and that rpcrt4 gets loaded much later.

I guess from the shared memory. Duane

Re: Speeding up wineserver syncronization objects with shared memory
by David Howells Feb. 28, 2001

Feb. 28, 2001

I've got a lot of the wine support kernel module written now. Its system call latency seems to be down at near half that of Win2000 for mutexes, though there's no guarantee that my benchmark programs produce meaningful numbers. I've also got PE Image mapping done (with pages fixed up on demand and marked as discardable). So if anything, Wine might want to steal that if the module as a whole is not used. This bit requires virtually no changes to the kernel itself, just half a dozen or so extra symbols to be exported. The module image size stands currently at about 30K. Status: PART STATE ====================================== ========================== General object infrastructure done HANDLE infrastructure mostly done Waiting calls partly done Exception handling not done Win32 error handling not done, uses UNIX errno UNICODE handling ignored, all ASCII Security handling ignored Mutex objects done Semaphore objects done Event objects done File objects (synchronous access) mostly done File objects (asynchronous access) not done Shared memory objects mostly done Process objects slightly done Thread objects slightly done Registry objects not done NT Port objects not done NT Token objects not done W2K Job objects not done Net Communications not done userspace access library up to date strace mostly up to date Cheers, David

PostScript driver demand loading
by Ian Pilcher Feb. 27, 2001

Feb. 27, 2001

The attached patch removes the explicit load of the PostScript driver from MAIN_GdiInit. Instead, when a function calls DRIVER_FindDriver to get a drivers DC_FUNCTIONS, DRIVER_FindDriver will attempt to load a named driver if it hasn't already registered itself. This appears to work for printing from Lotus Notes. I'd appreciate some feedback from people using other applications, however. Also, any thoughts on the approach in general would be welcome.

The call to WINPROC_GetPtr results from a call to > LoadLibraryExA ("COMCTL32.DLL" ...); here is the stack: Sounds like importing winspool.drv in wineps creates a circular load dependency (user32->gdi32->wineps->winspool->comctl32->user32). We could probably be a bit more clever about loading wineps only when really necessary; OTOH there is no reason for winspool.drv to require comctl32.

winspool.drv initialization problem

The saga continues! I've gotten my modified version of the PostScript driver to load, but it seems to causing/exposing another problem. WINPROC_GetPtr is being called befor WINPROC_Init during Wine initialization. The call to WINPROC_GetPtr results from a call to LoadLibraryExA ("COMCTL32.DLL" ...); here is the stack: #0 HEAP_GetPtr (heap=0) at heap.c:217 #1 0x40093514 in HeapValidate (heap=0, flags=0, block=0x408ffc67) at heap.c:1508 #2 0x4081c93f in WINPROC_GetPtr () from /usr/lib/wine/libuser32.so #3 0x4081cbaa in WINPROC_SetProc () from /usr/lib/wine/libuser32.so #4 0x407e280d in RegisterClassA () from /usr/lib/wine/libuser32.so #5 0x40900058 in ANIMATE_Register () from /usr/lib/wine/libcomctl32.so #6 0x40906412 in COMCTL32_LibMain () from /usr/lib/wine/libcomctl32.so #7 0x400814e8 in PE_InitDLL () from /usr/lib/wine/libntdll.so #8 0x4007d0f9 in MODULE_InitDLL () from /usr/lib/wine/libntdll.so #9 0x4007d216 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #10 0x4007f364 in LoadLibraryExA () from /usr/lib/wine/libntdll.so #11 0x4007f916 in LoadLibraryA () from /usr/lib/wine/libntdll.so #12 0x40975772 in WINSPOOL_EntryPoint () from /usr/lib/wine/libwinspool.drv.so #13 0x400814e8 in PE_InitDLL () from /usr/lib/wine/libntdll.so #14 0x4007d0f9 in MODULE_InitDLL () from /usr/lib/wine/libntdll.so #15 0x4007d216 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #16 0x4007d1f0 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #17 0x4007f364 in LoadLibraryExA () from /usr/lib/wine/libntdll.so #18 0x4007f916 in LoadLibraryA () from /usr/lib/wine/libntdll.so #19 0x4087206b in MAIN_GdiInit () from /usr/lib/wine/libgdi32.so #20 0x400814e8 in PE_InitDLL () from /usr/lib/wine/libntdll.so #21 0x4007d0f9 in MODULE_InitDLL () from /usr/lib/wine/libntdll.so #22 0x4007d216 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #23 0x4007d1f0 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #24 0x4007d1f0 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #25 0x4007d1f0 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #26 0x4007d1f0 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #27 0x4007d1f0 in MODULE_DllProcessAttach () from /usr/lib/wine/libntdll.so #28 0x400c758c in start_process () from /usr/lib/wine/libntdll.so #29 0x400caeed in SYSDEPS_DoCallOnStack () from /usr/lib/wine/libntdll.so #30 0x400caf97 in SYSDEPS_CallOnStack () from /usr/lib/wine/libntdll.so #31 0x400cb03a in SYSDEPS_SwitchToThreadStack () from /usr/lib/wine/libntdll.so #32 0x400c79d7 in PROCESS_InitWine () from /usr/lib/wine/libntdll.so #33 0x804b213 in main () #34 0x4027ff55 in __libc_start_main (main=0x804b1f8 <main>, argc=1, ubp_av=0xbffff9d4, init=0x8048728 <_init>, fini=0x804b25c <_fini>, rtld_fini=0x4000e3e4 <_dl_fini>, stack_end=0xbffff9cc) at ../sysdeps/generic/libc-start.c:129 This is way out of my depth! -- ======================================================================== Ian Pilcher pilcher(a)concentric.net ========================================================================

That seems > reasonable. No, that's not my concern. The probability of error doesn't matter at all, I don't mind if the process locks the mutex by accident. What must not be able to happen is that the process somehow corrupts the state as seen from the wineserver or other processes. That is, it doesn't matter if the process thinks it got the mutex when it didn't; but it must not be possible to make the wineserver see two processes holding the mutex, or some other inconsistent state. Any inconsistency must remain local to the process. > Yeah, but that doesn't seem fundamental --- the wineserver can always take > ownership of the mutex itself when it needs to do a complex atomic > operation. I'll let Gavriel work out the details :-). My point is that getting the details right is what is important; and if you are not interested in doing this, then there is no point in arguing any further. -- Alexandre Julliard julliard(a)winehq.com

undefined symbol: GetPrinterDataA
by Ian Pilcher Feb. 26, 2001

Feb. 26, 2001

I am trying to modify the Wine PostScript driver to use GetPrinterDataA to read configuration information from the registry. I have added a line that reads "import winspool.drv" to wineps.spec, and Wine builds with no errors. When I try to run Wine, however, I get the following error: BUILTIN32_dlopen failed to load .so lib for builtin wineps.dll: /usr/lib/wine/libwineps.so: undefined symbol: GetPrinterDataA Ideas? -- ======================================================================== Ian Pilcher pilcher(a)concentric.net ========================================================================

Anyway, I > think 100% reliability is possible for any plausible definition. For a mutex the basic definition is obviously that you can never have two threads holding the mutex at the same time, and that when it is released some other thread has a chance at grabbing it. This has to be true no matter what the process does, including corrupting memory or crashing. You also need to make sure nothing a process does should be able to crash/hang the wineserver or another process (except if they fight over the same mutex of course), and then there is the small matter of respecting the Win32 semantics... Actually it is the last constraint that is the main problem. You can certainly provide some kind of mutexes using shared memory; but we don't need just 'some kind', we need Win32 mutexes. This means a mutex is identified by a handle that can be manipulated by CloseHandle or DuplicateHandle; it means you need to detect and handle abandoned mutexes; it means you must support WaitForMultipleObjects, including the 'all' case where you cannot grab the mutex unless all objects are signaled; all things that I didn't see in your implementation ;-) -- Alexandre Julliard julliard(a)winehq.com
