Now, I don't pretend to understand the issues here, but reading your patch, http://www.winehq.org/hypermail/wine-patches/2004/11/att-0041/01-patch__cha… I see the comment * ... there is a race with SuspendThread(): the app * can call SuspendThread() then GetThreadContext() whilst the * target is processing SIGUSR1 but before it's been able to * override the thread context, ie the context returned would be * meaningless to the app (internals of Wine itself). I understand similar races are present in real Windows, too. e.g. http://blogs.msdn.com/cbrumme/archive/2003/08/20/51504.aspx says "[with SuspendThread,] there’s a significant risk of leaving a thread suspended at a “bad” spot. If you call SuspendThread while a thread is inside the OS heap lock, you better not try to allocate or free from that same heap. In a similar fashion, if you call SuspendThread while a thread holds the OS loader lock (e.g. while the thread is executing inside DllMain) then you better not call LoadLibrary, GetProcAddress, GetModuleHandle, or any of the other OS services that require that same lock. Even worse, if you call SuspendThread on a thread that is in the middle of exception dispatching inside the kernel, a subsequent GetThreadContext or SetThreadContext can actually produce a blend of the register state at the point of the suspension and the register state that was captured when the exception was triggered. If we attempt to modify a thread’s context (perhaps bashing the EIP – on X86 – to redirect the thread’s execution to somewhere it will synchronize with the GC or other managed suspension), our update to EIP might quietly get lost." I guess we just need to have races no worse than in Windows :-) About RT signals - I would tread carefully here. RT signals are a precious resource. The queue is not very deep, and it's *per system* on Linux IIRC. When I used RT signals for I/O, they overflowed the queue all the time -- and if any program in the system is doing that, it affects your program, since the queue is shared. - Dan -- Trying to get a job as a c++ developer?

winipcfg.exe issues
by Saulius Krasuckas Nov. 7, 2004

Nov. 7, 2004

[s2(a)katleriai antras]$ /sbin/ifconfig | grep ^[^\ ] eth0 Link encap:Ethernet HWaddr 00:50:22:80:F0:49 lo Link encap:Local Loopback ppp0 Link encap:Point-to-Point Protocol If run winipcfg with Wine, it lets me to change the adapter I want to inspect by selecting its name in combox (as usually). But if I hold the down-key pressed down for some seconds, Wine terminates the application: [s2(a)katleriai antras]$ wine /home/s2/cc/Program\ Files/winipcfg.exe wine client error:21: no fd received for handle 88 While the key is pressed, adapter info is being periodically refreshed. Does that means the app leaks some handle? Or is this a bug in Wine? What debug channel would you recommend to use to see more details on this?

SetupComm insize 1600 outsize 1600
by MediaHost (TM) Nov. 7, 2004

Hi Wine Developers, Question: I need to use a Win app on Linux and everything seams fine, except that the communication with the serialport doesn't work. Well, also here, everything seams fine to me, so I want to get your advice. The only thing I could see is the unimplemented stub for "SetupComm insize outsize". Can I set it by my own (setserial) or what's the meaning of it anyway? The output below seams to me pretty good...: fixme:comm:SetupComm insize 1600 outsize 1600 unimplemented stub trace:comm:GetCommState handle 0x54, ptr 0x778ef948 trace:comm:GetCommState OK trace:comm:GetCommState bytesize 8 baudrate 2400 fParity 0 Parity 0 stopbits 1 trace:comm:GetCommState ~IXON ~IXOFF trace:comm:GetCommState fOutxCtsFlow 0 fRtsControl 1 trace:comm:GetCommState fOutxDsrFlow 0 fDtrControl1 trace:comm:GetCommState ~CRTSCTS trace:comm:SetCommState handle 0x54, ptr 0x778ef948 trace:comm:SetCommState bytesize 8 baudrate 1200 fParity 0 Parity 0 stopbits 1 trace:comm:SetCommState ~IXON ~IXOFF trace:comm:SetCommState fOutxCtsFlow 0 fRtsControl 1 trace:comm:SetCommState fOutxDsrFlow 0 fDtrControl1 trace:comm:EscapeCommFunction handle 0x54, function=5 trace:comm:EscapeCommFunction SETDTR trace:comm:EscapeCommFunction handle 0x54, function=4 trace:comm:EscapeCommFunction CLRRTS trace:comm:SetCommTimeouts (0x54,0x778ef934) trace:comm:PurgeComm handle 0x54, flags 4 trace:comm:PurgeComm handle 0x54, flags 8 ]# cat /proc/tty/driver/serial serinfo:1.0 driver:5.05c revision:2001-07-08 0: uart:16550A port:3F8 irq:4 baud:2400 tx:11 rx:0 RTS Best Regards Signer: Eddy Nigg Company: StartCom Linux at www.startcom.org MediaHostT at www.mediahost.org Skype: startcom

Re: D3D8
by Ann and Jason Edmeades Nov. 7, 2004

Nov. 7, 2004

All I can say is any assistance with the d3d8/9 stuff is very gratefully accepted! If you have any questions or want help, feel free to drop me a note or post on wine-devel, and I'll try to respond. As per Lionel's note, I'm trying to move all the code into wined3d and make d3d8 and d3d9 call it, effectively making only one place to maintain so there is a lot of churn at the moment. It should settle in a couple of months (Once I get my latest patch in, things will move faster as well, once I know the way to solve certain problems). If you want suggestions as to what to work on, there's enough areas :-) - One I would say needs doing at some point is to take eg. 3dMark2002se, and get figures for it (I'd be interested if someone has a dual boot windows/linux machine to get comparisons on time), and try some profiling to work out where the time is spent and speed things up! - Apart from that, pick a game, and get the graphics right! - Or search the web for d3d8 (or 9, when it's there) demos which don't work and you have the source as well to, as you then know where to target in Jason

STL with WINE problems
by Dagan Shai Nov. 7, 2004

Nov. 7, 2004

Hi, I'm trying to compile a C++ file using WINE. The file includes STL's map. I am using STLPort with WINE. I get a long list of errors starting with: /starhome/iu/wine/include/wine/msvcrt/cstdlib:97: `div' not declared /starhome/iu/wine/include/wine/msvcrt/cstdlib:102: `ldiv' not declared /starhome/iu/wine/include/wine/msvcrt/cstdlib: In function `ldiv_t std::div(long int, long int)': /starhome/iu/wine/include/wine/msvcrt/cstdlib:122: `ldiv' undeclared (first use this function) /starhome/iu/wine/include/wine/msvcrt/cstdlib:122: (Each undeclared identifier is reported only once for each function it appears in.) /starhome/iu/wine/include/wine/msvcrt/cstdlib: At global scope: /starhome/iu/wine/include/wine/msvcrt/cstdlib:138: `lldiv_t' not declared /starhome/iu/wine/include/wine/msvcrt/cstdlib:139: `_Exit' not declared ... I'm using msvcrt as the C library. I saw a previous posting with the same problem, and I've tried the various solutions suggested (toggling -mno-cygwin, using STLPort) but that did not work. Suggestions welcome. Thanks, Shai Dagan

D3D8
by Joel Konkle-Parker Nov. 7, 2004

Nov. 7, 2004

In trying to get Guild Wars to work, I've come across the lack of D3D8 support in Wine. I'd like to try to help on this front, but I'm not sure who to talk to or where to start. Cedega has D3D8 support, but I'm presuming that if I contribute there, my code won't migrate back to base Wine. Can anyone lead me in the right direction here? -- Joel Konkle-Parker Webmaster [Ballsome.com] E-mail [jjk3(a)msstate.edu]

Countering arguments against Wine
by Dan Kegel Nov. 7, 2004

Nov. 7, 2004

I've run into people several times who dislike the fact that I advocate or even work on the Wine project, because they feel that it takes focus away from working on the Linux desktop. I beg to differ, but I've never had a really snappy comeback for them. It happened again today, and this time it occurred to me I should write a page on the topic to organize my thoughts. Here it is: http://www.kegel.com/wine/why.html Comments welcome. Thanks, Dan -- Trying to get a job as a c++ developer? See http://kegel.com/academy/getting-hired.html
