Upon recreation of the RandR internal data structures in RRCrtcNotify() the
crtc of an output could be NULLed if the crtc was shared (cloned) between two
outputs and one of them got another crtc assigned.
at CodeWeavers for the patch. From his description:
Fix a display bug with the X server. The Generic Rootless extension
installs overrides for certain GC (graphics context) operations. Within
these overrides, they temporarily uninstall themselves, perform their work,
and then reinstall themselves. Except sometimes they would return early
and wouldn't reinstall themselves when they should. Now they do in all cases.
Fix a bug in RootlessCopyWindow where early returns could leave the screen's
dispatch table entry for CopyWindow unwrapped. We think that this is
another case (hopefully the last) of the rootless drawing bug.
window to another Space, it will work correctly (as opposed
to just leaving a ghost window). We accomplish this by listening
for the notification from Xplugin that our window has been moved,
and then we ask X11 to move the window to the new location.
but the XC-QUERY-SECURITY-1 authorization method and the SecurityPolicy
configuration file have been removed. The semantics of the trusted vs.
untrusted split have been changed. This will be documented in a future
commit.
This fixes an undefined symbol error happening when compiling
the server with the --disable-xv configure switch.
Basically, xnest was linking against
@XSERVER_LIBS@ and @XNEST_LIBS@ and the order of the libraries
given to the linker at the end of the process was bogus.
* configure.ac: make XNEST_LIBS contain the $XSERVER_LIBS re-ordered
in such a way that the linker finds the symbols of all the libs contained
in $XNEST_LIBS.
* hw/xnest/Makefile.am: don't link against @XSERVER_LIBS@ anymore because
XNEST_LIBS contains the right thing.
For a few of us, the license statement is identical, and the only variant is
the copyright. For these, aggregate the copyrights, and only list the license
once. Put this at the top, and note that this is more or less our agreed
canonical license.
XkbRemoveResourceClient wants to access xkbInfo if it exists, so make
sure we NULL it after freeing it. It doesn't make much sense to move
the RemoveResourceClient call first, as there's not much point in
notifying clients while we're shutting the server down anyway.
Subject: [PATCH] fix some performance gaps in Xace
The XaceHook function is used in several hotpaths.
The problem with it (performance wise) is twofold:
* The XaceHook function has a big switch() statement for the hook number in it
* The XaceHook function uses varargs to reassemble the final dispatch arguments again
Both are expensive operations... for something that is known at compile time
This patch turns the hotpath XaceHook call into a direct call to avoid
the switch and varargs; this gives me over 10% performance gain
on the x11perf benchmark.
The code in connect_hook incorrectly checks for dbus_bus_request_name failure.
The dbus_bus_request_name error indicator is -1, not 0. This leads
to subsequent assertion failure in libdbus.
