Set isMaster for VCP/VCK.
Init sprites for master pointer devices.
Pair master kbds with master pointers (1:1 pairing!).
Attach other devices to VCP/VCK.
For now, we don't allow attaching slaves to other slaves, and we don't allow
pairing slaves with other slaves.
Pairing is for master keyboard->master pointer only.
Attaching is for slave device->master device only.
"master" points to the device this device is attached to. Event sent by the
device will also be routed through the master.
master and spriteOwner are mutually exclusive.
We re-pair them with the VCP, not a real device! If we would do otherwise,
somebody may change our keyboard focus and thus get us typing where we don't
want to type.
If the pairing client is not set, then the pairing is initiated internally
(e.g. when a new keyboard device is configured). In this case we _must_ pair
regardless of who is the pairing client.
In some cases a button press may activate a passive core grab. If the client
owning the passive grab already has a core grab on another device, don't
actually activate it. Otherwise the client gets two simultaneous passive
core grabs, and may never ungrab the device again (only if the other grab uses
GrabModeSync).
Reproducable: fire up gnome-session, open up gnome-terminal. Click with the
ClientPointer onto the window decoration, then click with another pointer onto
an application icon in the panel. Drag the icon out, release the button and
voila - you just lost your second mouse.
This is a half-assed attempt at getting rid of some enter-leave problems. When
a grab is activated, the events didn't get sent before, leading to interesting
results. This commit papers over it but doesn't actually fix it properly. The
whole enter/leave (focusin/out) structure needs to be ripped out and changed
for multiple devices.
We only get core events through the EQ in exceptional cases, so make sure we
actually swap the core keymap for XI events as well. Gives us back the ability
to have multiple keyboard layouts simultaneously.
DGAStealXXXEvent modified to take in device argument.
The evdev driver only sends one valuator when only one axis changed. We need
to check for DGA either way (xf86PostMotionEventP), otherwise we lose purely
horizontal/vertical movements.
Note that DGA does not do XI events.
Center the frame around the first pointer found and then update all pointers
on the same screen to move to the edges (if necessary).
Note: xf86WarpCursor needs to be modified, is using deprecated
miPointerWarpCursor and will kill the server when called with
inputInfo.pointer.
Let the drivers only generate XI events and put those into the event queue.
When processing events, generate core events as needed. This fixes a number of
problems with XKB and the DIX in general.
The previous approach was to put core events and XI events as separate events
into the event queue. When being processed, the server had no knowledge of
them coming from the same device state change. Anything that would then change
the state of the device accordingly was in danger of changing it twice,
leading to some funny (i.e. not funny at all) results.
Emulating core events while processing XI events fixes this, there is only one
path that actually changes the device state now. Although we have to be
careful when replaying events from synced devices, otherwise we may lose
events.
Note: XI has precedence over core for passive grabs, but core events are
delivered to the client first.
This removes the wrapping added in 340911d724
We need it unconditionally in a few places, and the rest checked for NULL and
then set it to VCK anyway. So, fixing up all callers to appreciate the defined
return value.
Instead of hardcoding CoreProcessPointerEvent, actually try to unwrap properly
and then call the unwrapped processInputProc. Seems to be a better idea,
especially since it makes stuff actually work...
Followup to [1].
If a core grab causes the device to freeze, it overwrites the processInputProc
of the device. [1] would then overwrite this while unwrapping, the device
does not thaw anymore.
Changing this to only re-wrap if the processInputProc hasn't been changed
during the event handling.
[1] 340911d724
When processing events from the EQ, _always_ call the processInputProc of the
matching device. For XI devices, this proc is wrapped in three layers.
Core event handling is wrapped by XI event handling, which is wrapped by XKB.
A core event now passes through XKB -> XI -> DIX.
This gets rid of a sync'd grab problem: with the previous code, core events
did disappear during a sync'd device grab on account of mieqProcessInputEvents
calling the processInputProc of the VCP/VCK instead of the actual device. This
lead to the event being processed as normal instead of being enqueued for
later replaying.
