Regression in CreateDIBSection
by Mehmet YASAR May 10, 2002

May 10, 2002

Hi, the following patch incorporated in CVS may 3rd has broken BabyGammon (you can get it at http://www.directfichiers.com/babygammon/BAFR100DOGT90.EXE ) With it I have black background instead of the normal backgammon game.

I'm afraid that this is the wrong solution to this problem: People using sNprintf do this sometimes for security reasons. Just ignoring the length is very likely to cause some problems with applications that would have been otherwise secure (I'm thinking of chatclients etc). snprintf should either be implemented or the application simply should not work, but making a secure app insecure is not the way to go. ciao Jörg -- Joerg Mayer <jmayer(a)loplof.de> I found out that "pro" means "instead of" (as in proconsul).

Request For Comments: emulation of Windows file attributes on POSIX
by Jakob Eriksson May 10, 2002

May 10, 2002

I filed a bug that comments Wine can't create a HIDDEN file, so that Wine does not later find it with FindFirstFile(). http://bugs.winehq.com/show_bug.cgi?id=660 there was a little discussion there and I suggested a) a mode where Wine reads the special info from VFAT and NTFS filesystems. (linux kernel enhancement probably necessary) b) for POSIX filesystems, an emulation layer where Wine emulates the attributes by storing them in a special file in each directory. Andriy Palamarchuk commented with this: There are plans on integration with Samba and this functionality can be implemented there for communication with Windows machines. However, I can't decide whether it is worth to implement these features for Posix file system. I suggest you to discuss the matter on wine-devel. Is it worth it at all? Is it worth it if I implement it as a Wine learning exercise and all you Wine demigods have to do is either say "ok" or "bad, to slow, let's ditch it" or whatever. I don't understand that about Samba integration. Can they read the special attributes on VFAT and NTFS? Are they planning to emulate it? -- regards, Jakob Eriksson The wages of sin is debugging. -- Ron Jeffries

A little configure change help needed for the mingw/msys port.
by Steven Edwards May 9, 2002

May 9, 2002

Preface: If you have the time to help thanks, if not I will keep fighting with it and should be able To get it sooner or latter and thanks anyway. After the recent patch for cygwin I found the 2 changes I need to make to configure/configure.ac for a mingw host/target but I'm having trouble with the syntax of configure to get it to do what I need it to do. My current porting work has been based on some dirty hacks to configure that didn't Really fix the problem without breaking the checks for other platforms. Now I just need some help making These 2 changes. Change #1. at line 5552 its checking for dlopen which I think is in dlfcn.h. Mingw doesn't have this and I don't think the mingw port needs this but configure returns. else LIBEXT="a" fi This of course causes configure to bomb because we need to build a dll/so. I cant get my syntax right To let it know not to set LIBEXT=a here if it's a mingw host. Change #2 On line 9465 there is the $LIBEXT = so/$target_os *cygwin* check. If I make Change #1 via my dirty breaking of configure and I change the case $target_os to *mingw* then it generates My makefiles right. My problem is really stupid because if I copy the cygwin check and make a mingw check It bitches about unexepected EOF in the configure script where I'm just missing a if/fi or something. Like I said, its really minor. Once this is done then you should at least be able to ./configure on msys just like cygwin if they fix the dlltool/wrap on msys.

Help debugging wine with CAM app
by Kyle May 9, 2002

May 9, 2002

I'd like to get involved in wine development. I'm starting by trying to get wine to run my favorite CAM application. Anyone who could give me a little coaching on debugging would be much appreciated. I'm using a recent CVS download of wine. To replicate the problem, do: Download the zip file at ftp://ftp.actarg.com/pub/misc/mtc.tgz. Unzip it under /c/Program Files. Then CD into MTC/TurboNest/Program and run: winedbg TurboNst.exe --debugmsg trace+string,+relay 2>/tmp/debug.out Search in the debug file for the string: TURBONST.ent Right around there is about where it starts to go into an endless loop. I have been single stepping all around in there and I can't figure out what is going on. One wierd thing: In the debugger, do break INT_Int31Handler cont then single step into CallRMInt on line: if (!Dosvm.CallRMInt && !DPMI_LoadDosSystem()), it doesn't seem to call DPMI_LoadDosSystem() at the correct address it calls some other address which looks like a jump table of some kind I'm not sure if that's the problem, but in any case, there's a point soon thereafter where it gets stuck doing: trace:string:lstrcmpiA strcmpi "" and "TURBONST.ent" over and over again. One other interesting thing: I found out by accident that if I patch into wine an illegal operation as follows: Put into the last line of procedure: BOOL WINAPI SetCurrentDirectoryA( LPCSTR dir ) a command that access memory illegally such as: FIXME("TRUE:%s\n",drive); //drive is an int--not a string Then run the program. Wine reports the illegal memory access, but then goes on to run the program successfully (other than that the fonts look funny and that function doesn't work right). Anyone that has experience debugging wine, I'm interested in learning more about how to do it. If I can get some experience under my belt, I'd love to help developing wine and finding more bugs. Thanks in advance! Kyle Bateman

Possible fix for DLLSeparation, Bug #543
by Uwe Bonnes May 9, 2002

Hallo, appended patch exports FILE_DupUnixHandle() as wine_dup_unix_handle() from kernel32. As FILE_DupUnixHandle uses it's own server-call, I thinks we need it as wine-exported function.

Testframework primer needed
by Uwe Bonnes May 9, 2002

May 9, 2002

Hallo, I can't find a primer in the wine distribution. I think it should be included. Possible subjects: Writing good test, running test on wine and winxx, ... Also is there a directive for a failing test to immediatly abort or skip some part of the program flow? The reason I ask: Somwhow ../dlls/kernel/testfile.xxx was craeted readonly before and some test didn't erase it so it was left behind. On the next run dlls/kernel/tests/file.c test__hread went into an infinite loop about that, cluttering up the screen, making it hard to find the reason.
