Commit 982387011 causes a bug where starting weston results in a black screen
(if no clients are immediately started). The problem is that the offending
commit causes the compositor to not damage if a surface has an empty output
mask, which is the case for the fade surface, which is created by the
compositor. This patch updates the surface output_mask unconditionally,
and only skips sending out the events if there no client.
In cases where we know the surface bounding box doesn't change in the
next frame, we can limit redraws to only the outputs the surface is
currently on. We could do even better by forcing the transform
update so we know where the surface will be in the next frame, but
this is a much simpler first step.
When the entire output is transformed or we're capturing the output
for screenshot or video, disable all output specific overlays
(drm planes, hw cursors etc) and move all surfaces into the primary
plane.
When we analyze and accumulate damage prior to repainting, we need to
accumulate damage per plane, so that whatever damage a surface
contributes is accumulated in the plane that it's assigned to. Before,
we would always accumulate damge in the primary plane, which caused
repaints in the primary plane whenever a surface in a sprite or
framebuffer was damaged. Eliminating this repaint is a big win for
cases where we pageflip to a client surface or use a sprite overlay.
This also prepares for fixing the missing cursor updates, since we
now track damage to the cursor surface in a dedicated sprite plane.
This backend has not seen even build testing for months, presumably does
not even compile, and is starting to hinder development a little.

In the wl_seat conversion, struct wl_touch got fields for the focused
surface and the client resource for the input device being focused.
However, the conversion was incomplete: the old fields
weston_seat::touch_focus* we still used by the event dispatching code,
but the new code never set them. Therefore no touch events were ever
sent.
From weston_seat, remove the fields touch_focus, touch_focus_listener,
touch_focus_resource, and touch_focus_resource_listener. They are
replaced by the corresponding fields and listeners from struct
wl_touch.
While doing this, fix touch_set_focus().
If touch_set_focus() was called first with surface A, and then with
surface B, without being called with NULL in between, it would corrupt
the destroy_signal list. It was equivalent of calling wl_signal_add()
for different signal sources with the same listener without removing in
between.
Now, touch_set_focus() first removes focus and listeners, and then
attempts to assign focus if requested. If the target client has not
subscribed for touch events, the touch focus will now be NULL.
Before this patch, the touch focus was left to the previous surface.
NOTE: this patch depends on the patch "server: add lose_touch_focus()"
for Wayland.

When we hit a segv, it's often the case that we might crash again in
the attempt to clean up. Instead we introduce a minimal restore callback
in the backend abstraction, that shuts down as simply as possible. Then
we can call that from the segv handler, and then to aid debugging, we
raise SIGTRAP in the segv handler. This lets us run gdb on weston from
a different vt, and if we tell gdb
(gdb) handle SIGSEGV nostop
gdb won't stop when the segv happens but let weston clean up and switch vt,
and then stop when SIGTRAP is raised.
It's also possible to just let gdb catch the segv, and then use sysrq+k
followed by manual vt switch to get back.
Simply exit(1)'ing the program will leave the VT unusable, since
DRM backend's clean-up does not run.
After a backend has been initialised, prefer jumping to clean-up instead
of directly exiting.
This fixes the case where 'weston-launch -- -i 5' would leave the
console unusable.

Reported by Dima Ryazanov <dima@gmail.com> in
<1341937691-26234-1-git-send-email-dima@gmail.com> but we also need to
destroy callbacks when the surface is destroyed normally.
surface->damage is for when the contents of the surface changes. Instead,
use weston_surface_damage_below() to repaint the damaged area. We avoid
unecessary uploading shm and hw cursor contents this way.
Simplify RGB shader code and split off common code that could be reused.
This is preparatory work for YUV shaders.

Otherwise a surface.attach request might cause the input region to be
reset to the default value (the entire surface) causing it to receive
focus.
Tiago ran into this problem with xwayland.
When calling glTexSubImage2D for sub image updates for SHM surfaces the
changed rectangle was being wrongly calculated. This resulted in interesting
redraw artefacts for clients using SHM.
This happens when vt-switching away from the compositor (drm) or
giving keyboard focus to a different X window. Release the modifiers
so we don't get stuck modifiers. We'll update with the new keys down
when we come back.
weston_compositor_init is always called late because most
implementations can't initialise GL until fairly late in the game.
Split it into a base version with the same name, followed by
weston_compositor_init_gl which can be called later on.
This simplifies compositor-wayland, which no longer needs a separate
global handler just for wl_seat.

notify_modifiers will now synchronise Weston's internal state with the
XKB state, and send a modifier event if necessary. This eliminates the
need for update_modifier_state to have a return value at all.
Signed-off-by: Daniel Stone <daniel@fooishbar.org>
If update_state is true, then notify_key will continue to call
xkb_key_update_state to update the local state mask, as before this
commit. Otherwise, it will rely on the compositor to manually update
the state itself, for nested compositors.

X11 has a set of eight modifiers which we want to represent. Cache
their indices when we create a weston_xkb_info, so we can use this from
compositor-x11 to keep the state synchronised exactly between the host X
server and a nested Weston instance.

This is mainly for X11's benefit; the common case is using Logo+S to
take a screenshot, where GNOME Shell has grabbed Logo, and replays the
event down to the nested compositor after S is pressed. This means we
get an enter event with both Logo and S down, and even if Shell delivers
the key press event for S (which isn't mandatory, and not all window
managers do), then we never run the binding since notify_key realises
that S is already down and exits early.

When the focus changes, wl_keyboard_set_focus (and, as an added bonus,
wl_pointer_set_focus) will now send wl_keyboard::modifier events for us
if we store the modifier state in the right place, so we don't have to
worry about that anymore.

krh: Edited to make message a litle more precise and added a check to

Since we now batch up damage and only handle it at repaint time, we need
to apply it in case a buffer is destroyed so we don't lose it.
Ander found the problem, but we need to fix it in the compositor so we
don't change the behavior of the compositor.
weston_surface_update_transform() is typically called as part of the
repaint cycle so don't schedule a repaint here. There are still a couple
of places where we call weston_surface_update_transform() manually, but
they don't rely on the repaint being scheduled.
