This change checks for pixels with alpha == 0 and any non-alpha component

non-premultiplied and fixed up by multiplying the RGB components with the

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.

In patch 137ac094e7, Adam moved an
expensive call to UpdateCurrentTime out of the main dispatch
loop. That's a good change as the original fix from Chase was a bit
expensive. However, it breaks grab processing and so a couple of the
calls to UpdateCurrenTime need to be removed.
Input event processing can generate a stream of events; a button press
that activates a grab will send a press followed by a sequence of
enter/leave events. All of these should have the same time stamp on
the wire as they occur at the 'same' time.
More importantly, the grab time recorded in the device is pulled from
currentTime after all of the events are delivered, so if currentTime
doesn't match the time in the device event, then future grab
modifications will fail as the time marked in the device will be
'later' than the grab time known to the client (which is defined as
the timestamp from the activating input event).
A bit of history here -- it used to be that currentTime was driven
*entirely* by input events; those timestamps didn't even have to be
related to the system time in any way. Then we started doing ICCCM
stuff and people got confused when PropertyNotify events would have
the same timestamp even when delivered minutes apart because no input
events were delivered.
We added code in the server to go update the time, but only if no
input events were pending (so that the clock "wouldn't" go
backwards). The only places where this is necessary is in request
processing which may generate an event with a timestamp, and there
only at the very top of the request processing code so that the whole
request would be processed at the 'same time', just like events.

216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

Patch 3ab6cd31cb fixed Xinerama
interactions with font servers by not putting clients to sleep
multiple times. However, it introduced additional changes dealing with
libXfont routine returning Suspended more than once for the same
request. This additional change was to abandon processing of the
current request and free the closure data by jumping to
'xinerama_sleep' in each of the functions.
Font library functions shouldn't return Suspended more than once,
except for ListFontsWithInfo, which produces multiple replies, and
thus ends up returning Suspended many times during processing.
With the jump to xinerama_sleep occurring after the first reply was
processed, the closure for the request was freed and future calls into
the ListFontsWithInfo callback resulted in dereferencing freed
memory.
This patch removes the added branches, reverting the code to its
previous behaviour, which permitted multiple Suspended returns and
simply waited for the client to be signaled again so that the callback
could continue processing the request.

and DGA rely on device-specific unaccelerated data.
To ease integration add this as a second set to the ValuatorMask rather than
extending all APIs to carry a second, possibly NULL set of valuators.
Note that a valuator mask should only be used in either accel/unaccel or
standard mode at any time. Switching requires either a valuator_mask_zero()
call or unsetting all valuators one-by-one. Trying to mix the two will produce
a warning.
The server has a shortcut for changing a mask with the

For two ScreenRecs abs pointer positioning was working fine, but touch events

Cause is a missing offset by the screen coordinates, causing the root

tranformAbsolute has a pretty simple job, that of running the X/Y
values from a device through the transformation matrix. The tricky bit
comes when the current device state doesn't include one of the
values. In that case, the last delivered value is back-converted to
device space and used instead.
The logic was twisted though, confusing GCC's uninitialized value
detection logic and emitting warnings.
This has been fixed by changing the code to:
1) Detect whether the ValuatorMask includes X/Y values
2) If either are missing, back-convert the current values into ox/oy
3) When X/Y are present, set ox/oy to the current value
4) Transform
5) Store X/Y values if changed or if they were set before.

This reverts commit d90b5f8301.
Reverting for two reasons:
* the scaling does not work on devices that don't advertise resolution, and
the default resolution used (100 units/mm) is higher than most devices,
resulting in a significant slowdown of the touchpads.
* the scaling is still affected by resolution changing. The patch worked
before acceleration but since it maps into resolution-dependent dx/dy
coordinates the acceleration may distort the movement after the fact. So the
same input data generates different movements depending on the resolution.
This can't easily be fixed for all affected devices as synaptics has its own
velocity calculation method whereas wacom doesn't. So anything in the server
won't work for both at the same time.
Revert this for now, until a more integrated solution can be implemented.
The goal of all this is to get an x/y motion reflecting the motion
on the device, i.e. a circle on the device is a circle on the screen.
This is currently done by scaling the y coordinate depending on the screen
ratio vs device ratio. Depending on that ratio the movement on the y axis may
be accelerated (ratio < 1) or slowed (ratio > 1). This leads to the weird
effect that changing the screen ratio by plugging a new monitor changes the
speed of the touchpad.
Use a different algorithm: calculate the physical movement on the device, map
that to the same-ish distance on the screen, then convert that back into a
device-specific vector. This way we get the same mapping regardless of the
current screen dimensions.
Since the pointer accel code doesn't take device resolution into account, make
sure we apply our crazy mapping before we accelerate. This way we accelerate
resolution-independent.

If there is a selection left over from a previous execution of the

by the selection object. When the selection is then deleted in
InitSelections() after the call to dixResetPrivates(), the refcount
for its privates type goes negative and bad things happen.
To fix this, we should delete any existing selections before calling
dixResetPrivates(). This will properly release the selection's
privates and avoid the crash.

probably keep up with two or three abusive clients, and letting it burst
to 15ms should give you about all the timeslice you need for a

If you're running on a system with a 10ms granularity on SIGALRM, then

and overwriting the *c pointer to point to our copy instead of the
original. If we hit an error, once we free(c), reset c to point to
the original structure before jumping to the cleanup code that
references *c.
Since one of the errors being checked for is whether the server was
able to malloc(c->nChars * itemSize), the client can potentially pass
a number of characters chosen to cause the malloc to fail and the
error path to be taken, resulting in the read from freed memory.
Since the memory is accessed almost immediately afterwards, and the
X server is mostly single threaded, the odds of the free memory having
invalid contents are low with most malloc implementations when not using
memory debugging features, but some allocators will definitely overwrite
the memory there, leading to a likely crash.

if the grab type isn't XI2, grab->xi2mask is random. That random data may
have the enter/leave mask set, leading to events sent to the client that the
client can't handler.
Source of these errors:
_xgeWireToEvent: Unknown extension 131, this should never happen.
Simplest reproducer:
Start Xephyr, press button inside window, move out. As the pointer leaves
the Xephyr window, the errors appear.

If we have a client which has registered for a DeviceButton grab
be sure to pass this to CheckDeviceGrabAndHintWindow(). Since the
order of clients is arbitrary there is no guarantee that the last
client in the list is the one that belongs to this class.

XI 1.x only allows for first + num valuators, so if a device sends data for
valuators 0 and 2+ only (i.e. valuator 1 is missing) we still need to get
the data for that from somewhere.
XI 1.x uses the hack of an unset valuator mask to get the right coordinates,
i.e. we set the value but don't set the mask for it so XI2 events have the
right mask.
For an absolute device in relative mode, this broke in b28a1af55c, the
value was now always 0. This wasn't visible on the cursor, only in an XI 1.x
client. The GIMP e.g. sees jumps to x/0 every few events.
Drop the condition introduced in b28a1af55c, data in valuators is always
absolute, regardless of the mode.

grab->type is only non-zero for passive grabs. We're checking an active grab
here, so we need to check if the touch mask is set on the grab.
Test case: grab the device, then start two simultaneous touches. The
grabbing client won't see the second touchpoints because grab->type is 0
and the second touch is not an emulating pointer.
