The comment about ClientPtr also being defined in misc.h is outdated

It's still also in Xdefs.h, so the guard is still needed.

Olivier Fourdan 6b47321bc6 dix: Add optional terminate delay
When the command line option "-terminate" is used, it could be
interesting to give it an optional grace period to let the Xserver

This adds an optional parameter to the "-terminate" command line option
for this purpose.

v2: Use a delay in seconds instead of milliseconds
    (Martin Peres <martin.peres@mupuf.org>)
v3: Clarify man page entry, ensure terminateDelay is always >= 0,
    simplify TimerFree(). (Peter Hutterer <peter.hutterer@who-t.net>)

Hans de Goede 834a467af9 dix: Add GetCurrentClient helper
Request-handlers as registered in the requestVector array, always get
passed the clientPtr for the client which sent the request.
But the implementation of many request-handlers typically consists of
a generic handler calling implementation specific callbacks and / or
various helpers often multiple levels deep and in many cases the clientPtr
does not get passed to the callbacks / helpers.

This means that in some places where we would like to have access to the
current-client, we cannot easily access it and fixing this would require
a lot of work and often would involve ABI breakage.

This commit adds a GetCurrentClient helper which can be used as a
shortcut to get access to the clienPtr for the currently being processed
request without needing a lot of refactoring and ABI breakage.

Note using this new GetCurrentClient helper is only safe for code
which only runs from the main thread, this new variable MUST NOT be used
by code which runs from signal handlers or from the input-thread.

The specific use-case which resulted in the creation of this patch is adding
support for emulation of randr / vidmode resolution changes to Xwayland.
This emulation will not actually change the monitor resolution instead it
will scale any window with a size which exactly matches the requested
resolution to fill the entire monitor. The main use-case for this is
games which are hard-coded to render at a specific resolution and have
sofar relied on randr / vidmode to change the monitor resolution when going
fullscreen.

To make this emulation as robust as possible (e.g. avoid accidentally scaling
windows from other apps) we want to make the emulated resolution a per client
state. But e.g. the RRSetCrtc function does not take a client pointer; and is
a (used) part of the Xorg server ABI (note the problem is not just limited
to RRSetCrtc).

Ray Strode 8738ce85df dix: ensure work queues are cleared on reset
If the server resets, most client workqueues are cleaned up as the
clients are killed.

The one exception is the server's client, which is exempt from
the killing spree.

If that client has a queued work procedure active, it won't get
cleared on reset.

This commit ensures it gets cleared too.

Adam Jackson 3297a1c871 include: Remove ___CLIENTSIGNALALL_DEFINED___ copypasta
___CLIENTSIGNAL_DEFINED___ is a hack to work around the declaration of
ClientSignal both in our own headers and in <X11/include/fontproto.h>,
the latter of which is properly part of libXfont (1, only) but packaged
in xorgproto because we have made some mistakes. ClientSignalAll needs

Alan Coopersmith 73c63afb93 Xi: unvalidated lengths in Xinput extension [CVE-2014-8095]
Multiple functions in the Xinput extension handling of requests from
clients failed to check that the length of the request sent by the
client was large enough to perform all the required operations and
thus could read or write to memory outside the bounds of the request
buffer.

This commit includes the creation of a new REQUEST_AT_LEAST_EXTRA_SIZE
macro in include/dix.h for the common case of needing to ensure a
request is large enough to include both the request itself and a
minimum amount of extra data following the request header.

Even though -Wcomment doesn't mind it (in gcc or clang), the appearance
of */* confuses the syntax highlighter of some editors (eg. vim), and

Eric Anholt abf1202706 glx: Move the GLX variable caching what GL context is current to dix.
GLX is trying to track whether the context it wants is current, to
avoid the glFlush() (and the rest of the overhead) that occurs on all
MakeCurrent calls.  However, its cache can be incorrect now that
glamor exists.  This is a step toward getting glamor to coordinate
with GLX.

Keith Packard d89b42bda4 Clean up warnings in DIX
As usual, mostly const char changes. However, filter_device_events had
a potentially uninitialized value, 'raw', which I added a bunch of
checks for. I suspect most of those are 'can't happen', but it's hard
to see that inside the function.
