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.
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.
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.
GenericEvents can't be parsed to keyButtonPointer, and there's no guarantee
that it has a time field anyway. PlayReleasedEvent needs to store the millis
when we know it (core events, XI event) and just re-use them for GenericEvents.
Yes, this is a hack. But it looks like the time has zero significance anyway.
EnableDevices is (amongst others )called after a VT switch. We must not create
a new sprite or re-pair the device, otherwise we lose the input device setup
that we had before the VT switch.
This requires the devices to be in exactly the same order as before
the VT switch. Removing a device while on a different VT is probably a bad
idea.
The device state needs to be changed while processing the XI event. Core
events are always processed after XI, so by then the device is already set up
properly. However, we now rely on DeviceButtonMotionMask to be equal to
ButtonMotionMask. It already is, but stick a big fat warning in so nobody
attempts to change it.
This commit disables XKB for the VCK, thus essentially for all devices.
Temporarily anyway.
This reverts commit 6b055e5d97.
MPX relies on the XI event being delivered before the core event. Device grabs
break, amongst other things. I guess stuck modifiers need to be fixed some
other way.

We shouldn't be able to restrict events like Expose, etc. with device based
ACLs. So we just ignore all non-input events when checking for permissions.
A passive core grab doesn't specify the device, and is thus created with the
ClientPointer as device. When this grab is activated later, don't actually
activate the grab on the grab device, but rather change the device to the one
that caused the grab to activate. Same procedure for keyboards.
Makes core apps _A LOT_ more useable and reduces the need to set the
ClientPointer.
Only applies to core grabs!
Disclaimer: It's 6:51am. I'm trying to be as understandable as possible.
What was happening previously was this:
* Press Alt
* Extended event generated and processed: state is now Alt down once
* Core event generated
- keyboard switched: inherited state is Alt down once
- event processed: Alt down twice
* Release Alt
* Extended event generated and processed: state is now null
* Core event generated and processed: Alt down once
If we switch the order:
* Press Alt
* Core event generated:
- keyboard switched: inherited state is null
- event processed: Alt down once
* Extended event generated and processed: state is now Alt down once
* Release Alt
* Core event generated and processed: state is now null
* Extended event generated and processed: state is now null
When we carry over the previous state, it needs to be the _previous_ state
(state and modifiersPerKey), assuming that we're going to catch now-core
events for any of these. For example, if Ctrl is held down as we pivot, we
need to carry Ctrl over with a count of one, for which an extended + core
release will then clear. Carrying over the union of the previous state _and
the state resulting from the immediate action_ was what broke things.
Add support for HAL-based hotplugging, in which we just get the list of
input devices and properties from HAL. Requires an FDI which is not yet
in mainline HAL.
For some reason, my keyboard has 25 mouse buttons, but zero valuators. This
causes GPE to blow up spectacularly, trying to get (and set) co-ordinates from
devices without valuators. For now, just prevent this from ever happening,
and whack a dirty great FIXME in.
Make sure the font path is always 'built-ins' when we use built-in fonts,
rather than having it as a fixed path for a while, then clobbering it
halfway through startup.
Break up D-Bus into two components: a D-Bus core that can be used by any
part of the server (for the moment, just the D-Bus hotplug API, and the
forthcoming HAL hotplug API), and the old D-Bus hotplug API.
