-Release 1.1 (2007-11-04)
-========================
-
-This 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 <jamey@minilop.net>, with agreement from
-Josh Triplett <josh@freedesktop.org>.
-
- 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:<screen> 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:
- <http://gitweb.freedesktop.org/?p=xcb.git;a=commit;h=09e54c4a3c>
-
-* 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 <localfield> 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)
-============================
-
-Note: Version 0.9.4 of the test suite tool "check" provides a broken
-version of the AM_PATH_CHECK macro, which causes autoconf to fail due to
-insufficient quoting on the macro names it prints in its deprecation
-message. We have written a patch to fix this problem, available at:
-<http://bugs.debian.org/cgi-bin/bugreport.cgi/check-m4-am-path-check-use-quadrigraphs-in-macro-names-to-unbreak-autoconf.patch?bug=395466;msg=20;att=1>
-Version 0.9.4-2 of the Debian package for check includes this patch.
-Users of other distributions who want to re-autotool libxcb will need to
-apply this patch, use an older version of check, or wait for a fixed
-upstream version. This bug does not affect users who use the distributed
-tarballs and do not re-autotool.
-
-* Add library support for xcb-xinerama, using new protocol description
- from xcb-proto.
-* In the generated protocol code, define and use constants for opcode
- numbers rather than hard-coding them.
-* In the API conversion script, match only XCB-namespaced XID generators
- when converting to xcb_generate_id.
-* Quit treating xproto specially in Makefile.am: handle it like all the
- extensions.
-* Generate Doxygen documentation comments in the protocol stubs, and
- provide a Doxygen config file for building HTML documentation for XCB.
-* Add note to xcbxlib.h that nothing except Xlib/XCB should use it.
-* Extend test suite to test xcb_parse_display with NULL argument and
- display in $DISPLAY.
-
-
-Release 1.0 RC2 (2006-10-07)
-============================
-
-API changes
------------
-
-In our announcement of XCB 1.0 RC1, we proposed two API changes for
-community feedback:
-
- We would greatly appreciate API review in this final release
- candidate period. We've had some limited feedback that our attempts
- to impose static type safety on XIDs in C pose more a hindrance than
- a help, so we would appreciate discussion over whether this
- constitutes a "serious issue with the API". Some question also
- remains of whether xcb_poll_for_event should have the out-parameter
- 'error', now that XCB has a more uniform mechanism for reporting
- connection errors. Speak now on these points or leave us alone. ;-)
-
-Since we've received feedback agreeing with our proposed changes, and no
-objections or requests to keep the existing API, we made both changes
-and bumped the soname to libxcb.so.1.0.0 in preparation for the release
-of XCB 1.0.
-
-* Remove XID wrapper structures and replace them with uint32_t typedefs.
- XID union types like xcb_drawable_t and xcb_fontable_t also become
- uint32_t typedefs. The API conversion script now replaces xcb_*_new
- with calls directly to xcb_generate_id. This change makes
- xcb_generate_id part of the client API rather than the extension API,
- so move xcb_generate_id from xcbext.h to xcb.h.
-
-* Remove the 'int *error' out-parameter for xcb_poll_for_event.
- xcb_poll_for_event now shuts down the xcb_connection_t on fatal
- errors; use xcb_connection_has_error to check.
-
-The Xlib-specific API in libxcb-xlib also changed:
-
-* Stop exposing the XCB IO lock for Xlib's benefit, by removing
- xcb_get_io_lock from the Xlib-specific XCB API; instead, libxcb-xlib
- now provides xcb_xlib_lock and xcb_xlib_unlock.
-
-Code generation changes
------------------------
-
-* The code generator no longer implicitly imports xproto for extensions.
- xcb-proto 1.0 RC2 includes the corresponding change to explicitly
- import xproto in extensions that need it
-
-* The generated protocol headers now declare "struct foo", "union foo"
- or "enum foo", not just the typedef "foo" of an unnamed
- struct/union/enum type.
-
-Bug Fixes
----------
-
-* Make Plan 7 'checked' requests work correctly.
-
-Documentation improvements
---------------------------
-
-* Document xcb_generate_id.
-
-* Tutorial enhancements.
-
-
-Release 1.0 RC1 (2006-09-25)
-============================
-
-The Great XCB Renaming
-----------------------
-
-Rename API to follow a new naming convention:
-
-* XCB_CONSTANTS_UPPERCASE_WITH_UNDERSCORES
-* xcb_functions_lowercase_with_underscores
-* xcb_types_lowercase_with_underscores_and_suffix_t
-* expand all abbreviations like "req", "rep", and "iter"
-
-Word boundaries for the names in the protocol descriptions fall:
-
-* Wherever the protocol descriptions already have an underscore
-* Between a lowercase letter and a subsequent uppercase letter
-* Before the last uppercase letter in a string of uppercase letters
- followed by a lowercase letter (such as in LSBFirst between LSB and
- First)
-* Before and after a string of digits (with exceptions for sized types
- like xcb_char2b_t and xcb_glx_float32_t to match the stdint.h
- convention)
-
-Also fix up some particular naming issues:
-
-* Rename shape_op and shape_kind to drop the "shape_" prefix, since
- otherwise these types end up as xcb_shape_shape_{op,kind}_t.
-* Remove leading underscores from enums in the GLX protocol description,
- previously needed to ensure a word separator, but now redundant.
-
-This renaming breaks code written for the previous API naming
-convention. The scripts in XCB's tools directory will convert code
-written for the old API to use the new API; they work well enough that
-we used them to convert the non-program-generated code in XCB, and when
-run on the old program-generated code, they almost exactly reproduce the
-new program-generated code (modulo whitespace and bugs in the old code
-generator).
-
-Authors: Vincent Torri, Thomas Hunger, Josh Triplett
-
-In addition to the API renaming, the library SONAMEs have changed to
-libxcb.so and libxcb-extname.so. The library major version remains at 0,
-to become version 1 before 1.0 is released; the SONAME lowercasing means
-that this will not conflict with XCB 0.9 libraries.
-
-The header files have moved from /usr/include/X11/XCB/ to
-/usr/include/xcb/. The XML-XCB protocol descriptions have moved to
-/usr/share/xcb, with extension descriptions no longer relegated to an
-extensions/ subdirectory. The API conversion script api_conv.pl will fix
-references to the header files, and packages using pkg-config will
-automatically use the new library names.
-
-Error handling Plan 7
----------------------
-
-All request functions now come in an "unchecked" and "checked" variant.
-The checked variant allows callers to handle errors inline where they
-obtain the reply, or by calling xcb_request_check for requests with no
-reply. The unchecked variant uses the event queue for errors. Requests
-with replies default to checked, because the caller must already make a
-function call to retrieve the reply and can see the error at that time;
-the unchecked variant uses the suffix _unchecked. Requests without
-replies default to unchecked, because the caller will not necessarily
-expect to handle a response, and the checked variant uses the suffix
-_checked.
-
-Connection error handling
--------------------------
-
-Fatal connection errors now put the xcb_connection_t object into an
-error state, at which point all further operations on that connection
-will fail. Callers can use the new xcb_connection_has_error function to
-check for this state in a connection. Functions that return a
-connection, such as the xcb_connect function, may instead return an
-xcb_connection_t already in an error state.
-
-In the future we expect to add additional API for getting more
-information about the error condition that caused the connection to get
-into an error state.
-
-Smaller API changes
--------------------
-
-All functions that have been marked 'deprecated' up to now have been
-removed for this release. After XCB 1.0 is released, functions marked
-'deprecated' will be preserved until the end of time to maintain
-compatibility.
-
-XCB no longer provides a sync function. Most callers of this function
-should use xcb_flush instead, which usually provides the intended
-functionality and does not require a round-trip to the server. If you
-really need this functionality, either use xcb_get_input_focus like sync
-used to do, or use the xcb_aux_sync function from the xcb-aux library in
-xcb-util. However, note that we do not consider the libraries in
-xcb-util remotely stable yet.
-
-XCB no longer provides xcb_[extension_name]_init functions for each
-extension. These functions previously caused XCB to issue and process a
-QueryExtension request. Callers should now directly call
-xcb_get_extension_data on the xcb_[extension_name]_id, or use
-xcb_prefetch_extension_data if they do not need to force a round-trip
-immediately.
-
-The compatibility functions in xcbxlib.h, provided solely for use by
-Xlib/XCB, now exist in a separate library libxcb-xlib. We don't want to
-have to change the libxcb soname if we later change or remove the Xlib
-compatibility functions, and nothing except Xlib/XCB should ever use
-them. (Applications which use Xlib/XCB do not need this library either;
-Xlib/XCB only uses it internally.)
-
-The descriptions of several extensions have been updated to match the
-latest versions implemented in the X.org X server.
-
-GIT Repository split
---------------------
-
-Previously, several XCB-related projects all existed under the umbrella
-of a single monolithic GIT repository with per-project subdirectories.
-We have split this repository into individual per-project repositories.
-
-Josh Triplett and Jamey Sharp wrote a tool called git-split to
-accomplish this repository split. git-split reconstructs the history of
-a sub-project previously stored in a subdirectory of a larger
-repository. It constructs new commit objects based on the existing tree
-objects for the subtree in each commit, and discards commits which do
-not affect the history of the sub-project, as well as merges made
-unnecessary due to these discarded commits.
-
-We would like to acknowledge the work of the gobby team in creating a
-collaborative editor which greatly aided the development of git-split
-(as well as these release notes).
-
-Build and implementation fixes
-------------------------------
-
-XCB no longer needs proto/x11 from X.org; the XCB header xproto.h
-provides the definitions from X.h, named according to XCB conventions.
-
-XCB should now build with non-GNU implementations of Make.
-
-XCB properly handles 32-bit wrap of sequence numbers, and thus now
-supports issuing more than 2**32 requests in one connection.
-
-Fixed bugs #7001, #7261.

+* 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)
+============================
+
+Note: Version 0.9.4 of the test suite tool "check" provides a broken
+version of the AM_PATH_CHECK macro, which causes autoconf to fail due to
+insufficient quoting on the macro names it prints in its deprecation
+message. We have written a patch to fix this problem, available at:
+<http://bugs.debian.org/cgi-bin/bugreport.cgi/check-m4-am-path-check-use-quadrigraphs-in-macro-names-to-unbreak-autoconf.patch?bug=395466;msg=20;att=1>
+Version 0.9.4-2 of the Debian package for check includes this patch.
+Users of other distributions who want to re-autotool libxcb will need to
+apply this patch, use an older version of check, or wait for a fixed
+upstream version. This bug does not affect users who use the distributed
+tarballs and do not re-autotool.
+
+* Add library support for xcb-xinerama, using new protocol description
+ from xcb-proto.
+* In the generated protocol code, define and use constants for opcode
+ numbers rather than hard-coding them.
+* In the API conversion script, match only XCB-namespaced XID generators
+ when converting to xcb_generate_id.
+* Quit treating xproto specially in Makefile.am: handle it like all the
+ extensions.
+* Generate Doxygen documentation comments in the protocol stubs, and
+ provide a Doxygen config file for building HTML documentation for XCB.
+* Add note to xcbxlib.h that nothing except Xlib/XCB should use it.
+* Extend test suite to test xcb_parse_display with NULL argument and
+ display in $DISPLAY.
+
+
+Release 1.0 RC2 (2006-10-07)
+============================
+
+API changes
+-----------
+
+In our announcement of XCB 1.0 RC1, we proposed two API changes for
+community feedback:
+
+ We would greatly appreciate API review in this final release
+ candidate period. We've had some limited feedback that our attempts
+ to impose static type safety on XIDs in C pose more a hindrance than
+ a help, so we would appreciate discussion over whether this
+ constitutes a "serious issue with the API". Some question also
+ remains of whether xcb_poll_for_event should have the out-parameter
+ 'error', now that XCB has a more uniform mechanism for reporting
+ connection errors. Speak now on these points or leave us alone. ;-)
+
+Since we've received feedback agreeing with our proposed changes, and no
+objections or requests to keep the existing API, we made both changes
+and bumped the soname to libxcb.so.1.0.0 in preparation for the release
+of XCB 1.0.
+
+* Remove XID wrapper structures and replace them with uint32_t typedefs.
+ XID union types like xcb_drawable_t and xcb_fontable_t also become
+ uint32_t typedefs. The API conversion script now replaces xcb_*_new
+ with calls directly to xcb_generate_id. This change makes
+ xcb_generate_id part of the client API rather than the extension API,
+ so move xcb_generate_id from xcbext.h to xcb.h.
+
+* Remove the 'int *error' out-parameter for xcb_poll_for_event.
+ xcb_poll_for_event now shuts down the xcb_connection_t on fatal
+ errors; use xcb_connection_has_error to check.
+
+The Xlib-specific API in libxcb-xlib also changed:
+
+* Stop exposing the XCB IO lock for Xlib's benefit, by removing
+ xcb_get_io_lock from the Xlib-specific XCB API; instead, libxcb-xlib
+ now provides xcb_xlib_lock and xcb_xlib_unlock.
+
+Code generation changes
+-----------------------
+
+* The code generator no longer implicitly imports xproto for extensions.
+ xcb-proto 1.0 RC2 includes the corresponding change to explicitly
+ import xproto in extensions that need it
+
+* The generated protocol headers now declare "struct foo", "union foo"
+ or "enum foo", not just the typedef "foo" of an unnamed
+ struct/union/enum type.
+
+Bug Fixes
+---------
+
+* Make Plan 7 'checked' requests work correctly.
+
+Documentation improvements
+--------------------------
+
+* Document xcb_generate_id.
+
+* Tutorial enhancements.
+
+
+Release 1.0 RC1 (2006-09-25)
+============================
+
+The Great XCB Renaming
+----------------------
+
+Rename API to follow a new naming convention:
+
+* XCB_CONSTANTS_UPPERCASE_WITH_UNDERSCORES
+* xcb_functions_lowercase_with_underscores
+* xcb_types_lowercase_with_underscores_and_suffix_t
+* expand all abbreviations like "req", "rep", and "iter"
+
+Word boundaries for the names in the protocol descriptions fall:
+
+* Wherever the protocol descriptions already have an underscore
+* Between a lowercase letter and a subsequent uppercase letter
+* Before the last uppercase letter in a string of uppercase letters
+ followed by a lowercase letter (such as in LSBFirst between LSB and
+ First)
+* Before and after a string of digits (with exceptions for sized types
+ like xcb_char2b_t and xcb_glx_float32_t to match the stdint.h
+ convention)
+
+Also fix up some particular naming issues:
+
+* Rename shape_op and shape_kind to drop the "shape_" prefix, since
+ otherwise these types end up as xcb_shape_shape_{op,kind}_t.
+* Remove leading underscores from enums in the GLX protocol description,
+ previously needed to ensure a word separator, but now redundant.
+
+This renaming breaks code written for the previous API naming
+convention. The scripts in XCB's tools directory will convert code
+written for the old API to use the new API; they work well enough that
+we used them to convert the non-program-generated code in XCB, and when
+run on the old program-generated code, they almost exactly reproduce the
+new program-generated code (modulo whitespace and bugs in the old code
+generator).
+
+Authors: Vincent Torri, Thomas Hunger, Josh Triplett
+
+In addition to the API renaming, the library SONAMEs have changed to
+libxcb.so and libxcb-extname.so. The library major version remains at 0,
+to become version 1 before 1.0 is released; the SONAME lowercasing means
+that this will not conflict with XCB 0.9 libraries.
+
+The header files have moved from /usr/include/X11/XCB/ to
+/usr/include/xcb/. The XML-XCB protocol descriptions have moved to
+/usr/share/xcb, with extension descriptions no longer relegated to an
+extensions/ subdirectory. The API conversion script api_conv.pl will fix
+references to the header files, and packages using pkg-config will
+automatically use the new library names.
+
+Error handling Plan 7
+---------------------
+
+All request functions now come in an "unchecked" and "checked" variant.
+The checked variant allows callers to handle errors inline where they
+obtain the reply, or by calling xcb_request_check for requests with no
+reply. The unchecked variant uses the event queue for errors. Requests
+with replies default to checked, because the caller must already make a
+function call to retrieve the reply and can see the error at that time;
+the unchecked variant uses the suffix _unchecked. Requests without
+replies default to unchecked, because the caller will not necessarily
+expect to handle a response, and the checked variant uses the suffix
+_checked.
+
+Connection error handling
+-------------------------
+
+Fatal connection errors now put the xcb_connection_t object into an
+error state, at which point all further operations on that connection
+will fail. Callers can use the new xcb_connection_has_error function to
+check for this state in a connection. Functions that return a
+connection, such as the xcb_connect function, may instead return an
+xcb_connection_t already in an error state.
+
+In the future we expect to add additional API for getting more
+information about the error condition that caused the connection to get
+into an error state.
+
+Smaller API changes
+-------------------
+
+All functions that have been marked 'deprecated' up to now have been
+removed for this release. After XCB 1.0 is released, functions marked
+'deprecated' will be preserved until the end of time to maintain
+compatibility.
+
+XCB no longer provides a sync function. Most callers of this function
+should use xcb_flush instead, which usually provides the intended
+functionality and does not require a round-trip to the server. If you
+really need this functionality, either use xcb_get_input_focus like sync
+used to do, or use the xcb_aux_sync function from the xcb-aux library in
+xcb-util. However, note that we do not consider the libraries in
+xcb-util remotely stable yet.
+
+XCB no longer provides xcb_[extension_name]_init functions for each
+extension. These functions previously caused XCB to issue and process a
+QueryExtension request. Callers should now directly call
+xcb_get_extension_data on the xcb_[extension_name]_id, or use
+xcb_prefetch_extension_data if they do not need to force a round-trip
+immediately.
+
+The compatibility functions in xcbxlib.h, provided solely for use by
+Xlib/XCB, now exist in a separate library libxcb-xlib. We don't want to
+have to change the libxcb soname if we later change or remove the Xlib
+compatibility functions, and nothing except Xlib/XCB should ever use
+them. (Applications which use Xlib/XCB do not need this library either;
+Xlib/XCB only uses it internally.)
+
+The descriptions of several extensions have been updated to match the
+latest versions implemented in the X.org X server.
+
+GIT Repository split
+--------------------
+
+Previously, several XCB-related projects all existed under the umbrella
+of a single monolithic GIT repository with per-project subdirectories.
+We have split this repository into individual per-project repositories.
+
+Josh Triplett and Jamey Sharp wrote a tool called git-split to
+accomplish this repository split. git-split reconstructs the history of
+a sub-project previously stored in a subdirectory of a larger
+repository. It constructs new commit objects based on the existing tree
+objects for the subtree in each commit, and discards commits which do
+not affect the history of the sub-project, as well as merges made
+unnecessary due to these discarded commits.
+
+We would like to acknowledge the work of the gobby team in creating a
+collaborative editor which greatly aided the development of git-split
+(as well as these release notes).
+
+Build and implementation fixes
+------------------------------
+
+XCB no longer needs proto/x11 from X.org; the XCB header xproto.h
+provides the definitions from X.h, named according to XCB conventions.
+
+XCB should now build with non-GNU implementations of Make.
+
+XCB properly handles 32-bit wrap of sequence numbers, and thus now
+supports issuing more than 2**32 requests in one connection.
+
+Fixed bugs #7001, #7261.
