To recap: the original XC-SECURITY extension disallowed background "None" if
the window was untrusted. XACE 1.0 preserved this check as a hook function.
XACE pre-2.0 removed the hook and first abolished background "None entirely,
then restored it as a global on/off switch in response to Bug #13683.
Now it's back to being per-window, via a flag instead of a hook function.
Sorry about the megacommit, but this touches on a lot of stuff.
Get rid of XkbFileInfo, which was pretty seriously redundant, and move the
only useful thing it had (defined) into XkbDescRec. defined will be removed
pretty soon anyway. Is the compat map pointer non-NULL? Then you have a
compat map, congratulations! Anyhow, I digress.
All functions that took an XkbFileInfoPtr now take an XkbDescPtr, _except_
XkmReadFile, which returns an XkbDescPtr *, because people want to deal in
XkbDescPtrs, not XkbDescRecs.
We need to start breaking the XKB API to enforce sanity, so drag whichever
headers we need to do so into the server tree, as the client API is set in
stone, being part of Xlib.
In some cases (triggered by a key repeat during a sync grab) XKB unwrapping
can overwrite the device's realInputProc with the enqueueInputProc. When the
grab is released and the events are replayed, we end up in an infinite loop.
Each event is replayed and in replaying pushed to the end of the queue again.
This fix is a hack only. It ensures that the realInputProc is never
overwritten with the enqueueInputProc.
This fixes Bug #13511 (https://bugs.freedesktop.org/show_bug.cgi?id=13511)

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.
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.

XI events can now take the same processing paths as core events, and should do
the correct state changes etc.
There's some cases where XKB will use KeyPress as type for an event to be
delivered to the client. Stuck warnings in, not sure what the correct solution
is yet.
(cherry picked from commit 6334d4e7be with some
additional compile fixes and non-MPX adaptations)
using a hardcoded ProcessKeyboardEvent. Otherwise we lose the ability to
process DeviceKeyEvents after the first key press.
This should be the correct fix now.

Using a global array for action filters is bad. If two keyboard hit a modifier
at the same time, releaseing the first one will deactivate the filter and
thus the second keyboard can never release the modifier again.

the hook - the hook only needs the Atom to control access to the selection
object. Upgraded the SelectionCallback to take a client argument and
additional type codes so that it can be used for redirection.
* configure.ac,include/dix-config.h.in: define the XEPHYR_DRI macro.
define it when --enable-xephyr and --enable-dri are both turned on.
* hw/kdrive/ephyr/XF86dri.c: copy this from mesa source to enable
Xephyr to talk DRI protocol the host X. In mesa, this is used by libGL.so to
talk DRI protocol with the server.
* hw/kdrive/ephyr/ephyr.c: finally initialise the DRI extension
in the ephyrInitScreen() function.
* hw/kdrive/ephyr/ephyrdri.c,ephyrdriext.c: safeguard the compilation
using the XEPHYR_DRI macro.
* dix/events.c, include/dix.h:
(UpdateSpriteForScreen): added this to update the mouse sprite context
when we switch from a pScreen to another.
* mi/mipointer.c:
(miPointerWarpCursor): as we are switching to a new pScreen,
don't forget to update the mouse sprite context.
Removes "LookupKeyboardDevice" and "LookupPointerDevice" in favor of
inputInfo.keyboard and inputInfo.pointer, respectively; all use cases
are non-XI compliant anyway.
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.
Add keyc->postdown, which represents the key state as of the last mieqEnqueue
call, and use it when we need to know the posted state, instead of the
processed state (keyc->down). Add small functions to getevents.c to query and
modify key state in postdown and use them all through, eliminating previously
broken uses.
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.
The pixman headers have been located under pixman-1/ instead of pixman/ since
around 2007-08-06, and pixman-1.pc has the updated include paths to account
for this.
This reverts commit feb1b3e455.
Add support for HAL-based hotplugging, in which we just get the list of
input devices and properties from HAL. Requires an FDI which is not yet
in mainline HAL.
Break up D-Bus into two components: a D-Bus core that can be used by any
part of the server (for the moment, just the D-Bus hotplug API, and the
forthcoming HAL hotplug API), and the old D-Bus hotplug API.
This patch changes the semantics of manual redirect windows so that they no
longer affect the clip list of their parent. Doing this means the parent can
draw to the area covered by the child without using IncludeInferiors. More
importantly, this also means that the parent receives expose events when
that region is damaged by other actions.
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.
