The problem fixed by this patch can be reproduced on Linux with the
following steps.
- Access NULL pointer intentionally in ProcessOtherEvent on key press.
- Instead of saving core dump to a file, write it into a pipe.
echo "|/usr/sbin/my-core-dumper" > /proc/sys/kernel/core_pattern
- Dump the core by pressing a key.
While the core is being dumped into the pipe, the smart schedule timer
will cause a pending SIGALRM. Linux kernel stops writing data to the
pipe when there are pending signals. This causes the core dump to be
truncated. On my system I'm expecting a 6 MB dump but the size will be
60 kB instead. The problem is solved if we block the SIGALRM caused by
expired smart schedule timer.
I haven't been able to reproduce this problem in the following cases.
- Save core dump to a file instead of a pipe.
- kill -SEGV `pidof Xorg`
- Press a key to dump core while gdb is attached to Xorg.
- Give option -dumbSched to Xorg.
Also note that the fix works only when NoTrapSignals has the default
value FALSE. The problem can still be reproduced if error signals
aren't trapped. In addition to pending SIGALRM, there is a similar
problem with pending SIGIO from the keyboard driver during core dump.

A grep on xorg/* revealed there's no consumer of this define.
Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.
Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."

If absolute events were posted, dixflags got set conditionally on whether the
valuators are different from the last posted set of values.
If dixflags are undefined however, the DIX interprets them as relative
valuators. Fix this by making sure defining dixflags is always defined.

If you need to bail out the server, use Ctrl-Alt-Fx, or enable zapping
if it bothers you that much. If Ctrl-Alt-Fx is broken, nag me until
it's permanently fixed.
OsInitColors always just returned TRUE, so just remove calls to it and
insane special-case logic. Remove unused kcolor.c implementation, and
merge oscolor.h into oscolor.c since it was the only user. Remove
open-coded strncasecmp in oscolor.c.
Since we no longer need to call OsInitColors after reading the config
file, just call PostConfigInit() from one place, and move PM handling to
one place so we can install the signal handlers earlier.
With the MD/SD device hierarchy we need control over the generation of the
motion history as well as the conversion later before posting it to the
client. So let's not let the drivers change it.
No x.org driver currently uses it anyway, linuxwacom doesn't either so dumping
it seems safe enough.

KdInitOutput() used to enable Composite when it was disabled by default,
but now this hack prevents ``-extension Composite'' from working.
Remove it, as Composite is enabled by default anyway.
A few pieces of code were abusing this define for other purposes, which are
converted to #ifndef DEBUG instead. There should be no ABI consequences
to this change.
The rationale is that having the define in xorg-server.h also disables
assert() drivers, which is unexpected, and also difficult to avoid since
xorg-server.h is included in their config.h, and you can't put a #undef in
config.h. As for removing it from the server instead of moving it to an
internal header, we probably shouldn't have unnecessary assert()s in
critical server paths anyway, and if we do we could #define NDEBUG in the
specific cases needed.
Rather than letting the DDX allocate the events, allocate them once in the DIX
and just pass it around when needed.
DDX should call GetEventList() to obtain this list and then pass it into
Get{Pointer|Keyboard}Events.
These hints allow an acceleration architecture to optimize allocation of certain
types of pixmaps, such as pixmaps that will serve as backing pixmaps for
redirected windows.
* hw/kdrive/src/Makefile.am: use fb/fbcmap_mi.c
and not fb/fbcmap.c. This allows kdrive to take advantage of
extensions redefining the entry points of micmap.c stuff.
For instance it allows Xephyr to have a working GL, which is not
possible otherwise, because GL redefines mInitVisualsProc
to initialise its visuals.
This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive. This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it. No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.
over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other. Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested. The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.
Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
I exported the evdev driver to Xephyr server. I'm running it using something
like:
$ ./hw/kdrive/ephyr/Xephyr :1 -mouse evdev,,device=/dev/input/event4 -keybd \
evdev,,device=/dev/input/event1,xkbmodel=abnt2,xkblayout=br
It also closes /#5668.
and the Xephyr virtual mouse keeps alive. With this patch the semantic changes
turning '-pointer' && 'Xephyr virtual mouse' always false.
Now we can open a device pointer and pass its options in Xephyr's command line
without having other pointer unused.
The former <X11/extensions/XKBsrv.h> has been pulled into the server now as
include/xkbsrv.h, and the world updated to look for it in the new place,
since it made no sense to define server API in an extension header. Any
further work along this line will need to do similar things with XKBgeom.h
and friends.
