It +also contains a patch much like Novell's libxcb-sloppy-lock.diff. +Rationale from the commit message follows. The patch and this rationale +were authored by Jamey Sharp , with agreement from +Josh Triplett . + + I strongly opposed proposals like this one for a long time. + Originally I had a very good reason: libX11, when compiled to use + XCB, would crash soon after a locking correctness violation, so it + was better to have an informative assert failure than a mystifying + crash soon after. + + It took some time for me to realize that I'd changed the libX11 + implementation (for unrelated reasons) so that it could survive most + invalid locking situations, as long as it wasn't actually being used + from multiple threads concurrently. + + The other thing that has changed is that most of the code with + incorrect locking has now been fixed. The value of the assert is + accordingly lower. + + However, remaining broken callers do need to be fixed. That's why + libXCB will still noisily print a stacktrace (if possible) on each + assertion failure, even when assert isn't actually invoked to + abort() the program; and that's why aborting is still default. This + environment variable is provided only for use as a temporary + workaround for broken applications. + +Enhancements: +* Print a backtrace, if possible, on locking assertion failures. +* Skip abort() on locking assertions if LIBXCB_ALLOW_SLOPPY_LOCK is set. +* xcb_poll_for_event: Return already-read events before reading again. +* Output a configuration summary at the end of ./configure. + +Bug fixes: +* Don't hold the xlib-xcb lock while sleeping: that allows deadlock. +* Allow unix: style display names again. +* Bug #9119: test xcb_popcount +* Fix unit tests for FreeBSD +* NetBSD doesn't have AI_ADDRCONFIG: use it only if it's available. +* Require libXau >= 0.99.2; earlier versions have a broken .pc file +* Use substitition variables in xcb-xinerama.pc.in +* Update autogen.sh to one that does objdir != srcdir +* Add tools/* and autogen.sh to EXTRA_DIST. +* Doxygen can now be fully disabled if desired. + +Documentation improvements: +* Many fixes and updates to the tutorial. +* Iterators, requests, and replies get partial Doxygen documentation. + + Release 1.0 (2006-11-23) ======================== -- cgit v1.2.3
