1 Version 1.1.2 - 2007-06-03
4 * Fix CVE-2007-1667: Multiple integer overflows in the XGetPixel() and
5 XInitImage() functions.
6 * Bug #9279: Fixed a file descriptor leak.
8 * Xlib/XCB: Ensure _XReadEvents reads at least one new event and blocks for
9 exactly one event. Large performance improvement for XIfEvent and similar.
11 * Hold XCB's Xlib lock even when only the user lock (XLockDisplay) is held.
12 An Xlib client can query Display state, such as with NextRequest, while it
13 holds only the Xlib user lock (between XLockDisplay and XUnlockDisplay), so
14 XCB requests in other threads should be blocked when the Xlib user lock is
15 held. We acquire the lock even when XInitThreads was not called, so that
16 pure XCB code can use multiple threads even in an otherwise single-threaded
19 * Allow re-entrant Xlib calls from _XIOError.
20 Some libraries try to clean up X resources from atexit handlers, _fini, or
21 C++ destructors. To make these work, downgrade the Display lock to a user
22 lock (as in XLockDisplay) before calling exit(3). This blocks Xlib calls
23 from threads other than the one calling exit(3) while still allowing the
24 exit handlers to call Xlib.
26 * Xlib/XCB: Avoid re-crashing after _XIOError.
28 * Xlib/XCB: Only remove pending_requests when there are provably no more responses.
30 * For NetBSD, define XTHREADLIB and XTHREAD_CFLAGS.
32 * Bug #7703: Fixed XSetSizeHints() et al wrt use of uninitialized data.
33 Now only those fields of the respective hint struct are set that
34 are actually valid in the input data.
36 * Bug #10292: Fixed a memory leak related to XOpenDisplay() in the XCB code.
38 * Bug #7713: Initialize all of the event's fields before sending it.
40 * Bug #10562: Define _GNU_SOURCE on glibc systems.
42 * Use unistd.h to get getresuid() and friends, now that we have _GNU_SOURCE
45 * Switched function definitions from K&R to ANSI style.
47 * Many constness fixes.
49 * Fixed a few warnings.
51 * Fix 64bit issues with reallocation.
54 * Add man pages for XKB APIs.
55 (Volunteer needed to convert prototypes in man pages to ANSI C style...)
56 * Protect C comments and #defines in XKB man pages from being mangled by cpp
57 * Fix typo in nroff macro in XkbAddGeomOverlayKey.man
58 * Bug #9695: Fixed a few argument types in the XOpenIM manpage.
59 * Markup tweak for XOpenIM.
60 * Bug #9696: refer to XDefineCursor() instead of XDefineCusor().
61 * Bug #9697: Fixed documentation of XVisualInfo struct. The "depth" member
62 was said to be unsigned int, but it's signed.
65 * Update el_GR.UTF-8/Compose.pre to match changes in xkeyboard-config cvs.
66 * For nls/*.pre, allow people to comment lines by starting them with '##'.
69 * Add autogen.sh to EXTRA_DIST.
70 * Makefile.am: make ChangeLog hook safer
71 * Don't distribute the configure-generated XlibConf.h in tarballs.
73 Version 1.1.1 - 2006-11-30
75 The "xcompmgr is hard, let's go releasing" release
77 * Fix Bug #9154 and friends, to unbreak xcompmgr:
78 Always process an event for _XReadEvents, even if an error occurs.
79 Previously, process_responses (in the wait_for_first_event case called
80 from _XReadEvents) considered any return from xcb_wait_for_event
81 sufficient to think it had processed an event. If xcb_wait_for_event
82 returned an error, and no more events occurred before process_responses
83 called xcb_poll_for_event, process_responses would try to return with
84 dpy->head NULL, and would fail an assertion for the _XReadEvents
85 postcondition. Now, process_responses continues using xcb_wait_for_event
86 until it gets an event.
88 * Bug #9153: Fix access to freed memory.
89 The fix for bug #8622 introduced a smaller bug where _XReply would
90 read memory shortly after freeing it. This patch caches the needed
91 value in a stack-allocated variable before the heap-allocated memory
94 * libx11 doesn't use inputproto in public headers; don't require it in x11.pc.
95 Based on a Debian patch.
97 * Debian bug #354315: Clarify return value in XGetWindowAttributes man page.
98 Patch by Debian user Ross Combs.
101 Version 1.1 - 2006-11-23
103 * Add note in man-page that XListFontsWithInfo is not thread-safe. _XReply
104 drops the Display lock, so the value of dpy->request may change before
105 _XReply is called again. Jamey Sharp discovered this by inspection a few
108 * Fix Bug #8622, by fixing the response processing order for threaded apps.
109 process_responses (the common code for _XReply, _XReadEvents, and
110 _XEventsQueued) now handles responses in order, by adding condition variables
111 to the list of outstanding requests in dpy->xcb->pending_requests, and
112 blocking on them when those requests should get processed, to allow _XReply
113 to process them; if actually called from _XReply, it returns when _XReply's
114 request should get processed. _XReply broadcasts on its condition variable
115 after it has read its reply and re-acquired the display lock.
117 * Don't hold the display lock around callbacks to the application. This avoids
118 recursive locking of the display lock (which triggers an XCB locking
119 assertion), particularly with emacs.
121 * Add xcb-xlib dependency to x11.pc when built against XCB.
123 * Allocate the right amount of memory for dpy->lock_fns. Fixes a crash on

138 Dynamically generate internal manpage section using __libmanpagesuffix__ so that it actually matches the section if you don't use 3X11
141 Add correct Display locking to XKB functions.

143 XCB: check for and handle I/O errors in _XGetXCBBuffer.
146 Fix double open of compose file.
149 Version 1.1 RC1 - 2006-10-06
151 This release includes the Xlib/XCB work, which uses XCB as the Xlib transport
152 layer, and allows a client to use both Xlib and XCB on the same connection.
153 This allows clients to transition from Xlib to XCB incrementally.
155 Clients which link only to libX11, and do not use XCB, should not notice any
156 differences in this release. Clients desiring XCB interoperability should
157 additionally #include <X11/Xlib-xcb.h>, link to libX11-xcb, use
158 XGetXCBConnection(dpy) to obtain the underlying XCB connection, and then use
159 XCB functions directly on that connection.
161 Note that while a client can issue requests and handle their replies or errors
162 with either Xlib or XCB, only one can own and handle the event queue. By
163 default, Xlib must own the event queue, for compatibility with legacy Xlib
164 clients. Clients can use the function XSetEventQueueOwner immediately after
165 XOpenDisplay to let XCB own the event queue instead. Clients may not call
166 this function after processing any responses, as this will potentially lose
169 We expect to have an RC2 release corresponding to the Xorg RC2 schedule, which
170 should include additional internal architecture enhancements, but no
171 user-visible changes. 1.0 final should match RC2.
173 Other smaller changes in this release:
174 * correct ChangeLog generation
175 * support running lint and sparse
177 * fix man page for XUrgencyHint
178 * improve man pages for XGrabButton, XGrabKey, XGetWindowProperty
179 * new locales: as_IN.UTF-8, kn_IN.UTF-8, ml_IN.UTF-8, or_IN.UTF-8,
180 te_IN.UTF-8, ur_IN.UTF-8
181 * on systems with both UNIXCONN and LOCALCONN, try unix if local fails
182 * fix sparse warnings
183 * ansify static functions
