-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.

+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.
