The question is then, how can we track this down?
This actually turned out to be easier to track down than I thought. Using
process explorer on 'wmaker --for-real --no-polling --static' shows that the
only thing of interest it's doing is calling XSync().
A simple test-case (attached) which just calls XSync() shows exactly the same
behaviour, leaking 3 semaphores per call.
The call stack looks like
pthread_cond_init
xcondition_init at Xthreads.h
insert_pending_request at xcb_io.c:343
_XReply at xcb_io.c:368
XSync at Sync.c:48
main at test_xsync.c:19
After some staring at the code, I think the attached patch is perhaps the
correct place to add a matching xcondition_clear.

When using Task Manager I see that one of the two wmaker processes (the one started with wmaker --for-real) leaks handles with a rate of 30/sec right after stating up. When using process explorer from sysinternals I have to switch on Show unnamed handles and mappings under View to identify these handles as Semaphore types. Recompiling the latest version of WindowMaker-0.92.0 against the latest Xorg distribution has the same effect. I also checked running original WindowMaker-0.90.0-2 against cygwin-1.7 with all the latest packages installed and also recompiled WindowMaker-0.92.0 under cygwin-1.7 with the same effects. Can anybody confirm (at least the handle leaks in Task Manager) ? Yes, I can see the same handle leak in task manager with windowmaker. WindowManager-0.90.0-2 runs absolutely stable with no leaks under cygwin 1.5 before upgrading to latest Xorg. So I guess suspicion first falls that this leak is somewhere in one of the updated X DLLs... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
