Eric Anholt 1549e30372 Add a Meson build system alongside autotools.
This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far.  The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet.  The unit tests are also not done.

The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools.  meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

v2: Fix indentation nits, move version declaration to project(), use
    existing meson_options for version-config.h's vendor name/web.

Rui Matos 5611585b87 xwayland: Don't send KeyRelease events on wl_keyboard::leave
Commits 816015648f and
fee0827a9a made it so that
wl_keyboard::enter doesn't result in X clients getting KeyPress events
while still updating our internal xkb state to be in sync with the
host compositor.

wl_keyboard::leave needs to be handled in the same way as its
semantics from an X client POV should be the same as an X grab getting
triggered, i.e. X clients shouldn't get KeyRelease events for keys
that are still down at that point.

This patch uses LeaveNotify for these events on wl_keyboard::leave and
changes the current use of KeymapNotify to EnterNotify instead just to
keep some symmetry between both cases.

On ProcessDeviceEvent() we still need to deactivate X grabs if needed
for KeyReleases.

Peter Hutterer d13cb97442 ddx: add new call to purge input devices that weren't added
Special case for the systemd-logind case in xfree86: when we're vt-switched
away and a device is plugged in, we get a paused fd from logind. Since we
can't probe the device or do anything with it, we store that device in the
xfree86 and handle it later when we vt-switch back. The device is not added to
inputInfo.devices until that time.

When the device is removed while still vt-switched away, the the config system
never notifies the DDX. It only runs through inputInfo.devices and our device
was never added to that.

When a device is plugged in, removed, and plugged in again while vt-switched
away, we have two entries in the xfree86-specific list that refer to the same
device node, both pending for addition later. On VT switch back, the first one
(the already removed one) will be added successfully, the second one (the
still plugged-in one) fails. Since the fd is correct, the device works until
it is removed again. The removed devices' config_info (i.e. the syspath)
doesn't match the actual device we addded tough (the input number increases
with each plug), it doesn't get removed, the fd remains open and we lose track
of the fd count. Plugging the device in again leads to a dead device.

Fix this by adding a call to notify the DDX to purge any remainders of devices
with the given config_info, that's the only identifiable bit we have at this
point.

Adam Jackson 137ac094e7 dix: Push UpdateCurrentTimeIf down out of the main loop

    Date:   Wed Apr 18 11:15:40 2012 -0700

        Update currentTime in dispatch loop

Unfortunately this is equivalent to calling GetTimeInMillis() once per
request. In the absolute best case (as on Linux) you're only hitting the
vDSO; on other platforms that's a syscall. Either way it puts a pretty
hard ceiling on request throughput.

Instead, push the call down to the requests that need it; basically,
grab processing and event generation.

Alexander Volkov f4c3cac010 Xi: call UpdateDeviceState() even when the client is missing
The client window can be closed in the middle of a touch sequence,
e.g. Qt 4 closes popup windows on MousePress and Qt 5.5 will do it
on TouchBegin. In this case the state of mouse buttons will not be
updated on TouchEnd because ProcessTouchEvent() calls UpdateDeviceState()
only when the event has been sent to the client. It results in a
stuck left mouse button.

This patch leads to calling UpdateDeviceState() in case the client
can't be found.

Steven McDonald d7a2df0a74 Xi: block SIGIOs while copying device classes around
I've been seeing sporadic (anywhere from once every few days to 3-4
times a day) crashes and freezes in X. The problematic behaviour isn't
always the same, but I chose a particular incident to debug, and found
that X was segfaulting in updateMotionHistory, on line 575 of
dix/getevents.c.

After some further investigation, I found that the bug was being
triggered when a SIGIO was received in DeepCopyPointerClasses, between
the AllocValuatorClass call (line 540) and updating the to->valuator
pointer (line 545). AllocValuatorClass calls realloc() on to->valuator,
so between these lines, it's not guaranteed to point to allocated
memory.

It seems the SIGIO handler is calling updateMotionHistory, which is
reading the memory pointed to by to->valuator and getting a wrong value
for last_motion, which updates buff to point to wildly the wrong place
and thus generates a segfault when a memcpy() is done into buff.

I am attaching a patch which I've been running on that machine for the
past three days, and haven't yet observed any more crashing or freezing
behaviour. The patch simply calls OsBlockSIGIO while
DeepCopyDeviceClasses is in progress, as the state of the X server's
device data structures is not guaranteed to be in a consistent state
during that time.

If the grab is pointer async and keyboard sync, the keyboard events are stuck
in EnqueueEvent until some other pointer event terminates the grab.

Change this to check for the number of listeners. If we're about to deliver a
TouchEnd to a passive pointer grab, the number of listeners is already 1 -
pointer grabs always accept so other listeners were removed.

Ben Gamari c1d30b5bd7 Xi: Don't ActivateEarlyAccept POINTER_REGULAR listeners
Bug #71878 describes a bug resulting in the server ceasing to respond to
keyboard input after a touch event. The problem might be the following:

DeliverTouchBeginEvent tries to deliver an event to a listener of type
LISTENER_POINTER_REGULAR, taking the following if branch,

    if (listener->type == LISTENER_POINTER_REGULAR ||
        listener->type == LISTENER_POINTER_GRAB) {
        rc = DeliverTouchEmulatedEvent(dev, ti, ev, listener, client, win,
                                       grab, xi2mask);
        if (rc == Success) {
            listener->state = LISTENER_IS_OWNER;
            /* async grabs cannot replay, so automatically accept this touch */
            if (dev->deviceGrab.grab &&
                dev->deviceGrab.fromPassiveGrab &&
                dev->deviceGrab.grab->pointerMode == GrabModeAsync)
                ActivateEarlyAccept(dev, ti);
        }
        goto out;
    }

DeliverTouchEmulatedEvent succeeds.  The deviceGrab meets all
three of the conditions of the inner if, enters
ActivateEarlyAccept which then fails due to,

    BUG_RETURN(ti->listeners[0].type != LISTENER_GRAB &&
               ti->listeners[0].type != LISTENER_POINTER_GRAB);

That is, despite listener->type == LISTENER_POINTER_REGULAR. With my
non-existent knowledge of XINPUT, it seems like the solution here
might be to only ActivateEarlyAccept when listener->type ==
LISTENER_POINTER_GRAB.

Peter Hutterer 8eeaa74bc2 dix: when ungrabbing an active grab, accept pointer grabs (#66720)
Ungrabbing a device during an active touch grab rejects the grab. Ungrabbing
a device during an active pointer grab accepts the grab.

Rejection is not really an option for a pointer-emulated grab, if a client
has a button mask on the window it would get a ButtonPress emulated after
UngrabDevice. That is against the core grab behaviour.

Peter Hutterer 395124bd27 dix: always copy grabs, don't reference them
Introduced in xorg-server-1.13.99.901-2-g9ad0fdb. Storing the grab pointer
in the listener turns out to be a bad idea. If the grab is not an active
grab or an implicit grab, the pointer stored is the one to the grab attached
on the window. This grab may be removed if the client calls UngrabButton or
similar while the touch is still active, leaving a dangling pointer.

To avoid this, copy the grab wherever we need to reference it later. This
is also what we do for pointer/keyboard grabs, where we copy the grab as
soon as it becomes active.

Peter Hutterer 0eb9390f60 Xi: Don't emit a TouchEnd event to a frozen device
EmitTouchEnd calls DeliverTouchEvents directly instead of through
public.processInputProc. If a device is frozen, the TouchEnd is
processed while the device is waiting for a XAllowEvents and thus ends the
touch point (and the grab) before the client decided what to do with it. In
the case of ReplayPointer, this loses the event.

This is a hack, but making EmitTouchEnd use processInputProc breaks
approximately everything, especially the touch point is cleaned up during
ProcessTouchEvents. Working around that is a bigger hack than this.

Peter Hutterer a7d989d335 Xi: use public.processInputProc to replay the touch history
If a device is frozen in results to a grab, we need to enqueue the events.

This makes things complicated, and hard to follow since touch events are now
replayed in the history, pushed into EnqueueEvent, then replayed later
during PlayReleasedEvents in response to an XAllowEvents.

While the device is frozen, no touch events are processed, so if there is a
touch client with ownership mask _below_ the grab this will delay the
delivery and potentially screw gesture recognition. However, this is the
behaviour we have already anyway if the top-most client is a sync pgrab or
there is a sync grab active on the device when the TouchBegin was generated.

(also note, such a client would only reliably work in case of ReplayPointer
anyway)

If a TouchBegin is sent to a core client, that client is now the owner.

By the time the TouchEnd is being processed, the client cannot replay
anymore, so we can assume that this is the final touch end and we can clean
up the touch record.

Note: DeliverTouchEmulatedEvent is called for all listeners and immediately
bails out if the client is not the owner and thus shouldn't yet get the
event. Thus, check the return code.

Jasper St. Pierre e130a46ab4 Add support for XI2.3: Pointer barrier events and releases.
This adds support for clients that would like to get a notification
every time a barrier is hit, and allows clients to temporarily release
a barrier so that pointers can go through them, without having to
destroy and recreate barriers.

Jasper St. Pierre 482e0cb352 cursor: Move pointer barrier code over to XI
In order to send events to specific windows associated with the barrier,
we need to move the code that handles barriers to somewhere where it's
easier to construct and send events. Rather than duplicating XSync with
its XSyncSelectAlarm, re-use the existing XI infrastructure.

For now, just move a bunch of code over, rename some things, and initialize
the new structures, but still consider it a separate codebase. Pointer barrier
requests are still handled by XFixes, so this is a weird intermediate state.
It's unknown whether we'll add explicit requests to pointer barriers inside
XI.

XIAllDevices, a second client may still select for device X.

device, resulting in inconsistencies when selecting for events. Fix that,
responding with the right errors regardless of who selected what first.

Given the following scenario:

  2) client B selects for TouchBegin on window W for XIAllDevices
  3) client C selects for TouchBegin on window W with device E

Step 3 will fail with BadImplementation, because attempting to look up
XIAllDevices or XIAllMasterDevices with dixLookupDevices doesn't work.
This should succeed (or, if it was selecting for device D, fail with
BadAccess as it would be a duplicate selection).

As a special case, if a still physically active pointer emulated touch
has no listeners and the device is explicitly grabbed for pointer
events, create a new dix touch record for the grab only.

This allows for clients to "hand off" grabs. For example, when dragging
a window under compiz the window decorator sees the button press and
then ungrabs the implicit grab. It then tells compiz to grab the device,
and compiz then moves the window with the pointer motion. This is racy,
but is allowed by the input protocol for pointer events when there are
no other clients with a grab on the device.

Chase Douglas fc518cd9f5 End a pointer emulated touch event only on a "real" end event
Fake end events are generated by touch acceptance or rejection. These
should not end the touch point.

Chase Douglas 80d7d1ec6a On touch accept, only process end event for owner if it has seen the end
We still need to generate the touch ownership event to process the
ending of the touch event in the case where the owner has the end
already.

Chase Douglas cacdb9a740 Accept touch sequence for pointer listener after second event delivery
This is a bit of unimplemented code for touchscreen pointer emulation. A
pointer grabbing client currently never accepts the touch sequence. The
sequence must be accepted once any touch-derived event is irrevocably
delivered to a client.

The first pointer event, derived from a touch begin event, may be caught
in a sync grab and then replayed. This is essentially a revocable
delivery of an event. Thus, we must wait till a non-begin event is
delivered.

Chase Douglas 93c3340364 Only set XI2 mask if pointer emulation is for XI2 client
The current code returns a reference to memory that may not actually be
an XI2 mask. Instead, only return a value when an XI2 client has
selected for events.

Chase Douglas 4c1dfd2193 Check core event mask properly for pointer emulated touch events
The current code checks the core event mask as though it were an XI2
mask. This change fixes the checks so the proper client and event masks
are used.

Chase Douglas 32ece7c09b Ensure sequential touches are pointer emulated sequentially
Issue:
* Two sequential touches (i.e. down, up, down, up)
* Both are grabbed by a touch grab
* Both have a second listener in the form of a pointer grab or selection
* The second and first touches are rejected in that order

The first touch must be pointer emulated before the second touch, so the
second touch must be paused until the first touch is rejected or
accepted and all events are delivered to pointer clients.

This change ensures all pointer emulated events are emitted
sequentially. It necessarily imposes a delay on further touch events
when pointer grabs and selections are used, but there is no way around
it.

Chase Douglas 163b0f375d Update event type when delivering end event to a pointer listener
Just like when we deliver to a touch listener, we must convert a touch
end event to an update event for further clients. This also ensures that
the touch record is not deleted at the end of ProcessTouchEvent().
