Another debugging tutorial
by Mike Hearn May 19, 2005

May 19, 2005

This time, it's how to debug PE Explorer hanging when you double click on a DLL in the file open dialog (fixed in CVS). http://wiki.winehq.com/Debugging_the_PE_Explorer_file_open_dialog Newbie developers, I crave your feedback. Are these actually useful or am I wasting my time? Share and enjoy! thanks -mike

Im troubleshooting bug 2962 http://bigs.winehq.com/show_bug.cgi?id=2962 and I had the reporter revert to the october release. But when trying to compile it, it failed, so I told him to do make distclean.. Now he's getting the no rule to make target distclean... Im stumped as to what to do... Can someone help me out? Dustin

Detecting ulimit problem
by Eric Frias May 19, 2005

May 19, 2005

I just ran into bug 2609: http://bugs.winehq.org/show_bug.cgi?id=2609 which is that wine fails to initialize when the user has a ulimit for virtual memory (address space) set to less than around 1300MB. This is something wine could test for and issue a warning. I know this isn't technically a problem with wine, but it's pretty unusual for an application to require that much address space. A user might not even realize they have a limit set if they haven't encountered problems with other large applications. It looks like I'm at least the third person to encounter this, and a hint to look at ulimit instead of other things (like the overcommit_memory setting) would've saved me some time. Something like: struct rlimit address_limits; int required_address_space = 1024 * 1024 * 1400; /* 1400M */ getrlimit(RLIMIT_AS, &address_limits); if (address_limits.rlim_max < required_address_space) WINE_WARN("Your virtual memory limit is set to %dk, which will\nprobably prevent wine from loading correctly. If you get an error,\nincrease the limit with 'ulimit -v' to at least %dk.\n", address_limits.rlim_max / 1024, required_address_space / 1024); I don't know how to determine the exact amount of address space wine requires, since it seems to vary somewhat with the application -- 1300M is enough for notepad, our own winelib app requires at least 1375M. Would a warning like this be appropriate? Eric

Re: list: make LIST_FOR_EACH_ENTRY look more like a for loop

I think it would be best if we are > consistent with other for loops out there. I think they are perfectly consistent as they are. The common form of a for loop is something like 'for cursor in list', that's also what LIST_FOR_EACH does, so it makes sense to have LIST_FOR_EACH_ENTRY do the same. The extra 2 parameters are implementation details about the object structure, that are just fine at the end. -- Alexandre Julliard julliard(a)winehq.org

LIST_FOR_EACH_ENTRY is different to a for statement because LIST_FOR_EACH_ENTRY doesn't declare the start condition, end condition and iterator because these are defined by the macro itself. The parameters are really just defining what you are iterating on and what you are using. Rob
