Version 1.1.2 - 2007-06-03

* Security fixes:

  * Fix CVE-2007-1667: Multiple integer overflows in the XGetPixel() and

    XInitImage() functions.

  * Bug #9279: Fixed a file descriptor leak.

* Xlib/XCB: Ensure _XReadEvents reads at least one new event and blocks for

  exactly one event.  Large performance improvement for XIfEvent and similar.

* Hold XCB's Xlib lock even when only the user lock (XLockDisplay) is held.

  An Xlib client can query Display state, such as with NextRequest, while it

  holds only the Xlib user lock (between XLockDisplay and XUnlockDisplay), so

  XCB requests in other threads should be blocked when the Xlib user lock is

  held.  We acquire the lock even when XInitThreads was not called, so that

  pure XCB code can use multiple threads even in an otherwise single-threaded

  Xlib application.

* Allow re-entrant Xlib calls from _XIOError.

  Some libraries try to clean up X resources from atexit handlers, _fini, or

  C++ destructors. To make these work, downgrade the Display lock to a user

  lock (as in XLockDisplay) before calling exit(3).  This blocks Xlib calls

  from threads other than the one calling exit(3) while still allowing the

  exit handlers to call Xlib.

* Xlib/XCB: Avoid re-crashing after _XIOError.

* Xlib/XCB: Only remove pending_requests when there are provably no more responses.

* For NetBSD, define XTHREADLIB and XTHREAD_CFLAGS.

* Bug #7703: Fixed XSetSizeHints() et al wrt use of uninitialized data.

  Now only those fields of the respective hint struct are set that

  are actually valid in the input data.

* Bug #10292: Fixed a memory leak related to XOpenDisplay() in the XCB code.

* Bug #7713: Initialize all of the event's fields before sending it.

* Bug #10562: Define _GNU_SOURCE on glibc systems.

* Use unistd.h to get getresuid() and friends, now that we have _GNU_SOURCE

  defined.

* Switched function definitions from K&R to ANSI style.

* Many constness fixes.

* Fixed a few warnings.

* Fix 64bit issues with reallocation.

* Manpage fixes:

  * Add man pages for XKB APIs.

    (Volunteer needed to convert prototypes in man pages to ANSI C style...)

  * Protect C comments and #defines in XKB man pages from being mangled by cpp

  * Fix typo in nroff macro in XkbAddGeomOverlayKey.man

  * Bug #9695: Fixed a few argument types in the XOpenIM manpage.

  * Markup tweak for XOpenIM.

  * Bug #9696: refer to XDefineCursor() instead of XDefineCusor().

  * Bug #9697: Fixed documentation of XVisualInfo struct.  The "depth" member

    was said to be unsigned int, but it's signed.

* nls fixes:

  * Update el_GR.UTF-8/Compose.pre to match changes in xkeyboard-config cvs.

  * For nls/*.pre, allow people to comment lines by starting them with '##'.

* Build system fixes:

  * Add autogen.sh to EXTRA_DIST.

  * Makefile.am: make ChangeLog hook safer

  * Don't distribute the configure-generated XlibConf.h in tarballs.

Version 1.1.1 - 2006-11-30

The "xcompmgr is hard, let's go releasing" release

* Fix Bug #9154 and friends, to unbreak xcompmgr:

  Always process an event for _XReadEvents, even if an error occurs.

  Previously, process_responses (in the wait_for_first_event case called

  from _XReadEvents) considered any return from xcb_wait_for_event

  sufficient to think it had processed an event. If xcb_wait_for_event

  returned an error, and no more events occurred before process_responses

  called xcb_poll_for_event, process_responses would try to return with

  dpy->head NULL, and would fail an assertion for the _XReadEvents

  postcondition. Now, process_responses continues using xcb_wait_for_event

  until it gets an event.

* Bug #9153: Fix access to freed memory.

  The fix for bug #8622 introduced a smaller bug where _XReply would

  read memory shortly after freeing it. This patch caches the needed

  value in a stack-allocated variable before the heap-allocated memory

  is freed.

* libx11 doesn't use inputproto in public headers; don't require it in x11.pc.

  Based on a Debian patch.

* Debian bug #354315: Clarify return value in XGetWindowAttributes man page.

  Patch by Debian user Ross Combs.

Version 1.1 - 2006-11-23

* Add note in man-page that XListFontsWithInfo is not thread-safe.  _XReply

  drops the Display lock, so the value of dpy->request may change before

  _XReply is called again.  Jamey Sharp discovered this by inspection a few

  years ago.

* Fix Bug #8622, by fixing the response processing order for threaded apps.

  process_responses (the common code for _XReply, _XReadEvents, and

  _XEventsQueued) now handles responses in order, by adding condition variables

  to the list of outstanding requests in dpy->xcb->pending_requests, and

  blocking on them when those requests should get processed, to allow _XReply

  to process them; if actually called from _XReply, it returns when _XReply's

  request should get processed.  _XReply broadcasts on its condition variable

  after it has read its reply and re-acquired the display lock.

* Don't hold the display lock around callbacks to the application. This avoids

  recursive locking of the display lock (which triggers an XCB locking

  assertion), particularly with emacs.

* Add xcb-xlib dependency to x11.pc when built against XCB.

* Allocate the right amount of memory for dpy->lock_fns.  Fixes a crash on

  startup with gdk.

Matthias Hopf:

      Fix double open of compose file.

Version 1.1 RC1 - 2006-10-06

This release includes the Xlib/XCB work, which uses XCB as the Xlib transport

layer, and allows a client to use both Xlib and XCB on the same connection.

This allows clients to transition from Xlib to XCB incrementally.

Clients which link only to libX11, and do not use XCB, should not notice any

differences in this release.  Clients desiring XCB interoperability should

additionally #include <X11/Xlib-xcb.h>, link to libX11-xcb, use

XGetXCBConnection(dpy) to obtain the underlying XCB connection, and then use

XCB functions directly on that connection.

Note that while a client can issue requests and handle their replies or errors

with either Xlib or XCB, only one can own and handle the event queue.  By

default, Xlib must own the event queue, for compatibility with legacy Xlib

clients.  Clients can use the function XSetEventQueueOwner immediately after

XOpenDisplay to let XCB own the event queue instead.  Clients may not call

this function after processing any responses, as this will potentially lose

responses.

We expect to have an RC2 release corresponding to the Xorg RC2 schedule, which

should include additional internal architecture enhancements, but no

user-visible changes.  1.0 final should match RC2.

Other smaller changes in this release:

* correct ChangeLog generation

* support running lint and sparse

* Autoconf 2.60

* fix man page for XUrgencyHint

* improve man pages for XGrabButton, XGrabKey, XGetWindowProperty

* new locales: as_IN.UTF-8, kn_IN.UTF-8, ml_IN.UTF-8, or_IN.UTF-8,

  te_IN.UTF-8, ur_IN.UTF-8

* on systems with both UNIXCONN and LOCALCONN, try unix if local fails

* fix sparse warnings

* ansify static functions
