Screen mode retrieval/trace tool for Windows
by Denver Gingerich March 5, 2008

March 5, 2008

I am trying to trace the sequence of screen mode (resolution/bpp/refresh rate) changes that occur when StarCraft is run in Windows so that I can make Wine emulate Windows' behavior. Right now I'm trying to see exactly what resolution, bits per pixel, and refresh rate StarCraft is using. Unfortunately, I can't just go into Display Properties while StarCraft is running because it switches the resolution back when you Alt-Tab out of the game. My current plan is to install an SSH or telnet server on the Windows machine and run a command line tool to check the current screen mode while StarCraft is running. I have used a couple of command-line tools for changing the screen mode [1] [2], but neither of them have an option to list the current mode. Does anyone know of a tool or can anyone quickly create a tool that will list the resolution currently in use from the command line? I have tried using StraceNT [3] to see the parameters passed to ChangeDisplaySettingsEx (which is the function StarCraft uses to change the resolution), but it does not let me look at the DEVMODE structure that is passed in. Does anyone know of a trace tool that would let me do that? Based on my testing so far, there appears to be a discrepancy in how Windows and Wine set the refresh rate if none is specified on a resolution change. Wine always picks the first mode with a matching resolution, while Windows does not. My tests in Windows have shown that even though StarCraft asks for 640x480 and the first mode with that resolution has a 60 Hz refresh rate, Windows chooses a higher refresh rate. Unfortunately, I don't know exactly which refresh rate, but I can verify by sight that 60 Hz is not being used (the screen doesn't flicker as it would at 60 Hz). This discrepancy is why I wish to run further tests and acquire more precise information about the refresh rate being used. I am performing this testing according to a request in a previous thread [4]. If you have any questions about my testing, please let me know.

Here's some example output (cleaned up a bit by my perl script, http://kegel.com/wine/valgrind/valgrind-split-pl.txt) is at: http://kegel.com/wine/valgrind/logs-2008-03-03/vg-ws2_32_sock.txt That particular output file says Syscall param socketcall.sendmsg(msg.msg_iov[i]) points to uninitialised byte(s) at (within /lib/ld-2.6.1.so) by WSASendTo (socket.c:2674) by WS_sendto (socket.c:2827) by test_UDP (sock.c:1055) by func_sock (sock.c:1985) by run_test (test.h:406) by main (test.h:455) This means there may be a bug somewhere near some of the lines mentioned. Sadly, only filename are given, not directories, so you kind of have to guess whether the files in question are in the directory ws2_32 or ws2_32/tests (or somewhere else). The thing to do is to read and understand the test with the issue. The course of action will then be obvious :-) Did I mention you have to really understand the test? - Dan

Howdy, I'm trying to help find memory leaks for wine http://wiki.winehq.org/MemoryLeaks and I'm having some issues figuring out Valgrind. #1 How do you know if Valgrind is working properly (AKA everything is patched and working). #2 How do you decifer the output to start looking for bugs. Thanks for the help, Will

Only three DLLs still failing tests!
by Dan Kegel March 4, 2008

March 4, 2008

For me, only user32, gdi32, and urlmon are failing tests on linux these days. And there's only one failure in urlmon: stream.c. Jacek, can you have a look at that urlmon failure? It'd be cool to be down to just two dlls with test failures! - Dan

Wine preloader redux
by Dan Kegel March 4, 2008

March 4, 2008

Say, it looks like at some point in the past, an alternate approach was looked at for reserving special addresses: http://bugzilla.kernel.org/show_bug.cgi?id=2255 If that kernel issue were resolved, would that let us get rid of the preloader?

Summer of code 2008, looking for volunteers
by Maarten Lankhorst March 4, 2008

March 4, 2008

Hi all, I'm planning on being administrator for wine project with the summer of code 2008. I'm looking for mentor volunteers. If you don't know what that is read take some time to read through http://code.google.com/soc/2008/faqs.html If anyone is interested, please contact me privately. I'm also looking for project ideas, if anyone has an idea for a project for the summer of code, please update http://wiki.winehq.org/SummerOfCode . I would prefer projects that can be done by small changes at a time, like implementing changes to get an application to work, instead of something dractic like a dib engine. It should preferably be doable in 2 to 3 months by someone who doesn't have a lot of wine experience yet. I'm also looking for people who want to help out in other ways, like updating the wiki page and creating some additional information that would be useful to students. Cheers, Maarten.
