Re: Avoid non-portable signal(SIGCHLD, SIG_IGN)

I'm note sure whether that's related (in it's, unfortunately, beyond my knowledge of threads and/or Wine to debug this), but... With current CVS sources of Wine, every single Windows program I try fails with the following error: assertion "libc_sigaction" failed: file "../../scheduler/pthread.c", line 661 which stems from the following snippet of code: int sigaction(int signum, const struct sigaction *act, struct sigaction *oldact) { if (!libc_sigaction) { libc_sigaction = dlsym( RTLD_NEXT, "sigaction" ); assert( libc_sigaction ); } return libc_sigaction(signum, act, oldact); } The backtrace looks as follows: (gdb) bt #0 0x5c06cbac in kill () from /usr/lib/libc.so.4 #1 0x5c0ae152 in abort () from /usr/lib/libc.so.4 #2 0x5c08a14f in __assert () from /usr/lib/libc.so.4 #3 0x5c16c404 in sigaction (signum=12, act=0xbfbfdce0, oldact=0xbfbfdcc8) at ../../scheduler/pthread.c:661 #4 0x5c074f09 in getcwd () from /usr/lib/libc.so.4 #5 0x5c167400 in CLIENT_InitServer () at ../../scheduler/client.c:618 #6 0x5c1685ab in process_init (argv=0xbfbff2e4) at ../../scheduler/process.c:414 #7 0x5c1689e1 in __wine_process_init (argc=2, argv=0xbfbff2e4) at ../../scheduler/process.c:585 #8 0x5c02130b in wine_init (argc=2, argv=0xbfbff2e4, error=0xbfbfee90 "", error_size=1024) at loader.c:429 #9 0x3c000569 in main (argc=2, argv=0xbfbff2e4) at main.c:32 #10 0x3c0004ae in _start () Gerald -- Gerald "Jerry" pfeifer(a)dbai.tuwien.ac.at http://www.pfeifer.com/gerald/

Why can't you just avoid the hashing tricks entirely? That sounds like it might break on W2K/XP as well.

WINE flag

by KK singh

hi, I have a win32 application that plays some hashing tricks with HWND while running on win98 and uses the fact that on win98 HWND is always 16bit. This application is crashing on wine configured as win98 because HWND is something bigger than 16bit on wine. Now Can I Check from inside my application code, whether the application is running on linux or win98 If yes then I might be able to avoid those hashing tricks and solve the crash Regards kks __________________________________ Do you Yahoo!?

iphlpapi.dll implementation

by Juan Lang

Folks, in case anyone's looking, I've implemented most of the Get* functions of ip helper API included in Windows NT4 or Windows 98. I'm not planning to implement functions added in Win2K or XP at this time. Email me if interested. No, it's not vaporware, it's just not as well tested as I'd like. I'm hoping to tackle reducing code duplication in this DLL, wsock32, and netapi, and also remove wsock32's dependency on the UNIX socket includes. This has all been discussed before here in this thread: http://www.winehq.com/hypermail/wine-devel/2001/09/0042.html For interface enumeration and address (IP and MAC) getting, I use ioctls. This should aid portability (I've tested the ioctls on Linux, FreeBSD, and Solaris). Stats I still read from /proc. All this stuff is in its own file to keep less-portable code together.

Wine Regression

by Steven Tower

With the current cvs tree parts of the Agent news reader are broken. I don't know the exact date it last worked but it wasn't that long ago. When double clicking on a group that is empty, the dialog you would normally see that asks if youw ant to download x headers, or all available headers, etc displays, but only the border and title bar are drawn and then wine crashes. The bug does not occur in Crossover Office 2.0.0.

The guy that wrote our bootloader and task-manager is supposed to be working on our explorer clone. At some point the explorer clone is going to have to interface with a web-browser. In any case I want to see this OLE to GTK or bonobo integration support you are talking about. The more these applications can get along the better chance we have of moving people off of Windows on to Linux, ReactOS or anything else that comes along and does GNU. There are a 2 things I think WINE needs now before we will see a good WIDE. 1. Implement Xdnd to OLE support. Corel did some work on this but it never made it in to the main winehq tree. This would really help anyone porting a Windows application to Linux seeing as how everything on Windows uses OLE and KDE and GNOME both support Xdnd now. I thinking if it is done right then you could even have it both ways and build it as a dll under Mingw and use it with either kde-cygwin/gnome-cygwin or libw11 ported applications. (If anyone has a snapshot of the corel-wine CVS I would like to look at this) 2. Cleanup Ole*. Everything depends on OLE and it either doesn’t implement everything or calls way to many non-standard APIs. Now that codeweavers has started to fix the need for M$ dlls in crossover maybe it will get fixed. We cannot make much use of most of the WINE code until we can build working ole32 support. There are way to many win16isms, and 9xisms.
