2018-07-11x11: make sure event source is drainedGuido Günther
Otherwise running under Xvfb will not deliver any events. This results in e.g. weston-info reporting a 0x0 window size (which results in all sorts of problems).

2018-05-25backends: implement custom EGL and renderer initializationIlia Bozhinov
Compositors now have more control over how the backend creates its renderer. Currently all backends create an EGL/GLES2 renderer, so the necessary attributes for creating the context are passed to a user-provided callback function. It is responsible for initializing provided wlr_egl and to return a renderer. On fail, return 0. Fixes #987

2018-04-15x11 backend: Expose events mean "needs swap"Uli Schlachter
When the X11 server sends an expose event, that means that "this rectangle here (the event contains x,y,width,height) has undefined contents on your window; please redraw that". This means that we need a swap. However, so far the code does not actually enforce that a swap happens. For example, start rootston, switch to another workspace and then switch back. The rootston window will not be redrawn (before commit 52b058c2a31fb, it would just be fully white; after that commit it will show whatever was visible on the old workspace). This is because the drawing code concludes that nothing needs to be done. However, in fact a swap is necessary. This reverts commit e79d92458852373, because its optimisation is already done now: wlr_output_update_needs_swap() emits a signal, which is handled by wlr_output_damage with a call to wlr_output_schedule_frame(). This function does nothing if a frame is already pending. Thus, the optimisation from commit e79d92458852373 now happens implicitly. Signed-off-by: Uli Schlachter <psychon@znc.in>
2018-04-15x11 backend: Ignore expose if frame is pendingUli Schlachter
When resizing rootston with the mouse, the result is really slow. One can see that rootston needs quite a while for drawing the newly visible area. This is because every single expose event is handled on its own and causes (apparently) a full repaint or at least a swap. This commit improves things by only causing a new frame if none is pending already. With this change, there is almost no delay in rootston drawing the newly visible area.

2018-04-15x11_handle_input_event: Remove return valueUli Schlachter
handle_x11_event() and x11_handle_input_event() react to different kinds of events, so it does not make much of a difference if x11_handle_input_event() signals if it handled an event or not. Signed-off-by: Uli Schlachter <psychon@znc.in>
2018-04-15handle_x11_event: Remove return valueUli Schlachter
This function always returns "false", so its return type can simply be changed to void. Signed-off-by: Uli Schlachter <psychon@znc.in>

2018-03-26Fix use-after-free in x11 backend during shutdownUli Schlachter
The xcb_connection_t instance that is used here comes from XGetXCBConnection(), is created by XOpenDisplay(), and is owned by the returned Display*. Calling xcb_disconnect() directly on it leads to various use-after-frees during shutdown, as reported by valgrind. The first one of the about 30 errors is: Invalid read of size 4 at 0x71F2051: xcb_take_socket (in /usr/lib64/libxcb.so.1.1.0) by 0x78551DD: ???

However, XCloseDisplay() tries to clean up some internal caches first for which it has to send requests to the X11 server (e.g. the XFreeGC() above). This fails since the file descriptor was already closed, which causes an IO error. Xlib's _XDefaultIOError() handles this by printing an error message and calling exit(1). Thus, the only symptom of this problem was compositors exiting mid-shutdown and printing an error message: XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0" after 6 requests (6 known processed) with 0 events remaining.

2018-01-30backend: fix use-after-free when destroying backendsemersion
The backend destroy signal is emitted before the output_remove signal is. When the destroy signal is emitted listeners remove their output_remove listener, so the output_remove signal is never received and listeners have an invalid output pointer. The correct way to solve this would be to remove the output_remove signal completely and use the wlr_output.events.destroy signal instead. This isn't yet possible because wl_signal_emit is unsafe and listeners cannot be removed in listeners.
