xwayland: handle EAGAIN on Wayland fd
wl_display_flush() can fail with EAGAIN and Xwayland would make this a
fatal error.
When this happens, it means that Xwayland has flooded the Wayland file
descriptor, either because the Wayland compositor cannot cope or more
likely because of a deadlock situation where the Wayland compositor is
blocking, waiting for an X reply while Xwayland tries to write data to
the Wayland file descriptor.
The general consensus to avoid the deadlock is for the Wayland
compositor to never issue blocking X11 roundtrips, but in practice
blocking rountrips can occur in various places, including Xlib calls
themselves so this is not always achievable without major surgery in the
Wayland compositor/Window manager.
What this patch does is to avoid dispatching to the Wayland file
descriptor until it becomes available for writing again, while at the
same time continue processing X11 requests to release the deadlock.
This is not perfect, as there is still the possibility of another X
client hammering the connection and we'll still fail writing to the
Wayland connection eventually, but this improves things enough to avoid
a 100% repeatable crash with vlc and gtkperf.
Also, it is worth considering that window managers and Wayland
compositors such as mutter already have a higher priority than other
regular X clients thanks to XSyncSetPriority(), mitigating the risk.

This appears to be the result of xwl_cursor_confined_to() and
xwl_screen_get_default_seat(). While not against protocol, mutter ends
up sending xdg_output before wl_seat. xwl_screen_get_default_seat()
makes the naïve assumption that we always have a valid seat, we end up
returning a pointer to the empty list itself instead of an actual seat
and causing ourselves to segfault.
So, actually return NULL in xwl_screen_get_default_seat() if the seat
list is empty, and skip any pointer confinement processing in
xwl_cursor_confined_to() when we don't have a seat setup yet.

xwayland: handle EAGAIN on Wayland fd
wl_display_flush() can fail with EAGAIN and Xwayland would make this a
fatal error.
When this happens, it means that Xwayland has flooded the Wayland file
descriptor, either because the Wayland compositor cannot cope or more
likely because of a deadlock situation where the Wayland compositor is
blocking, waiting for an X reply while Xwayland tries to write data to
the Wayland file descriptor.
The general consensus to avoid the deadlock is for the Wayland
compositor to never issue blocking X11 roundtrips, but in practice
blocking rountrips can occur in various places, including Xlib calls
themselves so this is not always achievable without major surgery in the
Wayland compositor/Window manager.
What this patch does is to avoid dispatching to the Wayland file
descriptor until it becomes available for writing again, while at the
same time continue processing X11 requests to release the deadlock.
This is not perfect, as there is still the possibility of another X
client hammering the connection and we'll still fail writing to the
Wayland connection eventually, but this improves things enough to avoid
a 100% repeatable crash with vlc and gtkperf.
Also, it is worth considering that window managers and Wayland
compositors such as mutter already have a higher priority than other
regular X clients thanks to XSyncSetPriority(), mitigating the risk.

xwayland: handle EAGAIN on Wayland fd
wl_display_flush() can fail with EAGAIN and Xwayland would make this a
fatal error.
When this happens, it means that Xwayland has flooded the Wayland file
descriptor, either because the Wayland compositor cannot cope or more
likely because of a deadlock situation where the Wayland compositor is
blocking, waiting for an X reply while Xwayland tries to write data to
the Wayland file descriptor.
The general consensus to avoid the deadlock is for the Wayland
compositor to never issue blocking X11 roundtrips, but in practice
blocking rountrips can occur in various places, including Xlib calls
themselves so this is not always achievable without major surgery in the
Wayland compositor/Window manager.
What this patch does is to avoid dispatching to the Wayland file
descriptor until it becomes available for writing again, while at the
same time continue processing X11 requests to release the deadlock.
This is not perfect, as there is still the possibility of another X
client hammering the connection and we'll still fail writing to the
Wayland connection eventually, but this improves things enough to avoid
a 100% repeatable crash with vlc and gtkperf.
Also, it is worth considering that window managers and Wayland
compositors such as mutter already have a higher priority than other
regular X clients thanks to XSyncSetPriority(), mitigating the risk.

dix: Add hybrid full-size/empty-clip mode to SetRootClip
216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.
