release requires xcb-proto 1.1, due to the addition of the +extension-multiword attribute to the XML schema. + +This release contains several important bug fixes, summarized below. 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) +======================== + +The "Thanksgiving" release: We feel thankful to have it released. Five years +have passed since XCB's initial commit on September 3rd, 2001: + + +* Support IPv6. XCB now supports displays with IPv6 addresses, with or without + enclosing square brackets, or with hosts which resolve to IPv6 addresses, by + using getaddrinfo instead of gethostbyname, and by including support for + authentication for such connections. This allows such displays as "::1:1.1". + +* XCB now uses the libpthread-stubs, to properly support optional use of + pthreads even on platforms which do not have all the necessary pthread stubs + in libc or otherwise available by default. + +* Switch from the old AM_PATH_CHECK macro to pkg-config. check 0.9.4 is now + required to build XCB's unit tests. The version that we were requiring was + not actually new enough to let our unit tests compile, and the AM_PATH_CHECK + macro is now considered deprecated. We know that versions of check using + pkg-config are new enough to work, and the check dependency was optional + anyway, so we've dropped support for older versions. + +* Provide a xcb_prefetch_maximum_request_length counterpart to + xcb_get_maximum_request_length. + +* Fix Bug #5958: zero out padding bytes in requests. + +* Change xcb_connect to pass the display number to _xcb_get_auth_info, which + passes it to get_authptr. This allows get_authptr to stop hacking the + display number out of the sockaddrs of various address families, such as + port - X_TCP_PORT, or the number after the last X in the UNIX socket path. + +* Remove --with-opt and --with-debug options from configure.ac; configure + supports the use of custom CFLAGS, so please use that instead. + +* Reove support for the tag in protocol descriptions, since they + no longer use it, and since new protocol descriptions should not need it + either. + +* xcb-proto has no libraries or headers, so don't use XCBPROTO_CFLAGS or + XCBPROTO_LIBS. + +* XCB builds which use xdmcp now include it in Requires.private, to support + static linking. + +* Replace "long" with uint32_t when used for a 32-bit quantity + +* Various enhancements to the generation of documentation with Doxygen: + * Check for doxygen in configure.ac + * Fix some Doxygen warnings. + * Install documentation. + * Handle out-of-tree builds, with srcdir != builddir. xcb.doxygen now gets + generated from xcb.doxygen.in, so that it can use top_builddir and + top_srcdir to find source and to output documentation. + * Fill in PROJECT_NUMBER from @VERSION@, now that we have it readily + available via autoconf. + + Release 1.0 RC3 (2006-11-02) ============================
