Since the client is about to be freed, its ignore count doesn't matter and
AttendClient can simply be a no-op. Check for client->clientGone in AttendClient
and remove similar checks from two callers that had them.

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.
This removes the last uses of fd_set from the server interfaces
outside of the OS layer itself.

The screen block and wakeup handlers are the only ones which provide a
well known ordering between the wrapping layers; placing these as
close as possible to the server blocking provides a way for the driver
to control the flow of execution correctly.
Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.
Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.
These changes ensure that the following modules update the screen in
the correct order:
animated cursors (uses RegisterBlockAndWakeupHandlers dynamically)
composite (dynamic wrapping)
misprite (dynamic wrapping)
shadow (static wrapping)
glamor (static wrapping)
driver (static wrapping)
It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix
that, misprite should be wrapping during ScreenInit time and not
unwrapping. And composite might as well join in that fun, just to make
things consistent.
[v2] Unwrap BlockHandler in shadowCloseScreen (ajax)
[v3] ephyr: Use screen block handler for flushing changes
ephyr needs to make sure it calls glXSwapBuffers after glamor finishes
its rendering. As the screen block handler is now called last, we have
to use that instead of a registered block/wakeup handler to make sure
the GL rendering is done before we copy it to the front buffer.

GLX is trying to track whether the context it wants is current, to

glamor exists. This is a step toward getting glamor to coordinate

xf86i2c: add pscrn for drivers to use
This just adds a pScrn pointer into the struct for the drivers to use
instead of scrnIndex. Mostly scrnIndex is used for logging, but some
drivers use it to lookup xf86Screens, so let them stash a pScrn instead.
Removing the scrnIndex is a bit more involved and I'm not sure its worth
the effort. Doing i2c in the X server is legacy code as far as I'm concerned.

dixLookupWindow uses dixLookupDrawable internally, which returns
BadMatch when the XID matches a non-Window drawable. Users
of dixLookupWindow don't care about this, just that it's not
a valid Window.
This is a generalised version of the fix for X.Org Bug 23562,
where GetProperty was incorrectly returning BadMatch. Auditing other
window requests, all that I checked would incorrectly return BadMatch
in these circumstances. An incomplete list of calls that could
incorrectly return BadMatch is: ListProperties, SetSelectionOwner,
{Destroy,Map,Unmap}{,Sub}Window.
None of the callers of dixLookupWindow, except for GetProperty, check
for BadMatch

BlockHandler and WakeupHandlers may be removed within a different
BlockHandler or WakeupHandler, especially since config/udev uses
these and removes devices.
Calling the deleted handlers and passing potentially freed data
can result in the X server segfaulting after device removal, or
events that result in device removal such as undocking or suspend/
resume.

Rather than always returning BadValue, associate an error status like
BadWindow with a resource type like RT_WINDOW, and return the
appropriate one for the requested type.
This patch only touches the core protocol resource types. Others still
return BadValue and need to be mapped appropriately.
dixLookupResourceByType can now return BadImplementation, if the caller
asked for a resource type that has not been allocated in the server.

The only remaining X-functions used in server are XNF*, the rest is converted to

X* functions are still exported from server and x* macros are still defined in

This function was moved verbatim into libXfont-1.4, and it is not used
by the server or any drivers. Exporting it in both places leads to
multiple definition linking errors on Cygwin, where we need to use a
static libXfont due to poor weak-symbol handling.

dixLookupResource attempted to automatically detect whether the caller
wanted a lookup by-type or by-class, unfortunately, it guessed wrong for
RT_NONE. Instead of trying to make the guess better, this patch just reverts
the unification and creates separate functions for each operation.
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.
Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.
Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:

libXfont has stubs for these symbols, so, when compiling with hidden
symbols by default, these symbols must be visible in the X Server, or
the stubs in libXfont will be used.
Now that the code has been fixed so that Unmap means unmap and not "don't
remap", 'remap' was confusing to have in the function names/parameters, so
change it to simple 'map'.
