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.
Conflicts:
dix/getevents.c
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.
We need to do this to update the sprites x/y coordinate before we assemble a
button event. Absolute devices may send a buttonEvent with valuators attached.
If we don't update the sprite before assembling the event, the valuators are
lost and the button press is delivered to the previous position of the device.
Doesn't have any effect on relative devices.
This patch changes the semantics of manual redirect windows so that they no
longer affect the clip list of their parent. Doing this means the parent can
draw to the area covered by the child without using IncludeInferiors. More
importantly, this also means that the parent receives expose events when
that region is damaged by other actions.
We need this to allow extensions to fill in extra data for an event before it
is sent to the client. This is probably to be used like
FillUpEventsFromWindow().
DeletePassiveGrabFromList() may remove the window optional, so we need to
re-alloc it if it isn't there anymore.
Thanks to Colin Harrison for spotting the bug.
This is definitely necessary in CheckDeviceGrabAndHintWindow (thanks to Paulo
Zanoni for spotting it). We're resetting it everywhere else too, just to be
save.
Device drivers flush their buttons on device init and cause a button down
event to be generated. If we unconditionally decrease the buttons, we won't be
able to ever get a passive device grab.
Format documentation for CheckDeviceGrabs to make it readable.

Conflicts:
Xi/exevents.c
Is set when passive grab is implicit as result of a ButtonPress event. If this
is the case, we need to store the XI mask as well as the core mask to ensure
delivery of XI events during the grab's lifetime.
Remove all core grabs on other devices when client issues a GrabPointer or
GrabKeyboard request. Let's assume that the client really only wants one
device to interact, so this seems like a reasonable solution.

Before you complain, this code hasn't seen material change since at least
X11R6. It certainly does not build with any modern version of Kerberos.
Anybody wanting krb5 auth to their X server should probably be using
GSSAPI instead of internal krb5 API anyway.
This quickfixes event delivery problems with XI events when a grab was on.
deviceMask is only used when the grab was from a ButtonPress to preserve
potential XI event masks.
This is not an ideal solution but it works until I have time to work on
PassiveGrabs.
