If we inherited a signal mask from the parent process that ignores SIGUSR1,
then we will send SIGUSR1 to the parent to indicate when we're ready to
accept connections. Unfortunately, we send this notification way too
early, right after creating the sockets rather than just before entering
the main loop.
Move it to just before Dispatch() so we're not lying quite so much.
The smart scheduler itimer currently always fires after each request
(which in turn causes the CPU to wake out of idle, burning precious
power). Rather than doing this, just stop the timer before going into
the select() portion of the WaitFor loop. It's a cheap system call, and
it will only get called if there's no more commands batched up from the
active fd.
This change also allows some of the functions to be simplified;
setitimer() will only fail if it's passed invalid data, and we don't do
that... so make it void and remove all the conditional code that deals
with failure.
The change also allows us to remove a few variables that were used for
housekeeping between the signal handler and the main loop.

* GL/glx/glxvisuals.c: added boolean to disable
calling init_visuals(). This gives a chance to Xephyr
to take over visuals manipulation and avoid a crash at
server shutdown in __glXMesaScreenDestroy(), due to the fact
that mesa might sees more visual than what it has actually created in
init_visuals(). It might see more visuals because Xephyr can augment
the number of visuals, dynamically.
* os/utils.c: the boolean is actually defined here.
Because our "popen" implementation uses stdio, and because nobody's stdio
library is capable of surviving signals, we need to make absolutely sure
that we hide the SIGALRM from the smart scheduler. Otherwise, when you
open a menu in openoffice, and it recompiles XKB to deal with the
accelerators, and you popen xkbcomp because we suck, then the scheduler
will tell you you're taking forever doing something stupid, and the
wait() code will get confused, and input will hang and your CPU usage
slams to 100%. Down, not across.
This adds a bit of glue to configure.ac to support launchd detection;
on OS X (or other platforms which choose to implement launchd), this allows
the system to automagically start the Xserver as necessary to serve clients.
MAXBUFSIZE appears to be a leftover of some previous time. Instead, just
use maxBigRequestSize when bigreqs are available (limiting buffers to ~16MB).
When bigreqs are not available, needed won't be larger than the maximum
size of a non-bigreqs request (256kB).
Before you complain, this code hasn't seen material change since at least
X11R6. It certainly does not build with any modern version of Kerberos.
Anybody wanting krb5 auth to their X server should probably be using
GSSAPI instead of internal krb5 API anyway.
This adds (unconditional) support for the GE extension. Anything from now on
that sends events in MPX will have to use the GE extension. No GE, no MPX
events. GE is not actually used yet from anywhere with this commit.
You will need to update x11proto, xextproto, libX11, libXext and xcb to the
matching xge branches. Things will _NOT_ work without the updated protocol
headers and libraries.
Default core size limit for most environments is 0, which disables core
dumps. Add code in the -core option processing path to set the core limit to
the maximum value.
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.
This keeps us from having to define _POSIX_C_SOURCE, _BSD_SOURCE, and
_XOPEN_SORUCE to get the C environment we want in different places. It also
fixes the build on linux due to RTLD_DEFAULT having not been defined.
automake will not stop whining about the *.O files not being in normal library
name format, so just tell automake they are PROGRAMS so it builds them without
bitching.
