When the foot window is closed, and we need to terminate the client application,
do this in an asynchronous fashion:
* Don’t do a blocking call to waitpid(), instead, rely on the reaper callback
* Use a timer FD to implement the timeout before sending SIGKILL (instead of
using SIGALRM).
* Send SIGTERM immediately (we used to *just* close the PTY, and then wait 2
seconds before sending SIGTERM).
* Raise the timeout from 2 seconds to 60
Full shutdown now depends on *two* asynchronous tasks - unmapping the window,
and waiting for the client application to terminate.
Only when *both* of these have completed do we proceed and call term_destroy(),
and the user provided shutdown callback.
If the call to fdm_wayl() with EPOLLHUP was followed by calls to
wayl_roundtrip(), foot would hang.
The reason for this is that the EPOLLHUP handler in fdm_wayl() would
call wl_display_cancel_read().
wayl_roundtrip() also calls wl_display_cancel_read() (since we
normally have called wl_display_prepare_read()), before calling
wl_display_roundtrip().
When calling wl_display_cancel_read() two times in a row, without a
wl_display_prepare_read() in between, wl_display_roundtrip() hangs.
Fix by not calling wl_display_cancel_read() in fdm_wayl(). This
ensures our invariant holds: wl_display_prepare_read() is *always* in
effect outside of fdm_wayl().
Closes#651
We still use the primary font, but use a custom size, based on the
title bar’s height.
This fixes an issue where the window title could be way too small, or
way too big. And changed size when the terminal font size was changed.
Set clip region in render_osd(). This ensures we don’t step outside
the pixman buffer when rendering the glyphs.
Furthermore, don’t ignore the alpha channel in the background color.
Move render_osd() to make it visible to the render_csd_*() functions.
While we’re in scrollback search mode, the selection may be
cancelled (for example, if the application is scrolling out the
selected text). Trying to e.g. extend the search selection after this
has happened triggered a crash.
This fixes it by simply resetting the search match state when the
selection is cancelled.
Closes#644
