Subject: [PATCH] Re-enable SIGIO when waiting for events
Date: Sat, 11 Jul 2015 12:58:00 +0100
Pasting a large string into an Emacs tty frame causes
keyboard.c:kbd_buffer_store_buffered_event to call ignore_sigio()
which sets SIGIO to SIG_IGN.
Unfortunately no-one seems to ever re-enable the SIGIO handler.
This leads to timeouts when attempting to paste into an Emacs X11
frame as reported at
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=16737 .
It appears that keyboard.c:kbd_buffer_get_event used to re-enable the
signal handler but that was removed as part of a large signal-handling
clean up in 4d7e6e51dd4acecff466a28d958c50f34fc130b8.
Reinstating the re-enabling of SIGIO in kbd_buffer_get_event solves
the problems reported in bug 16737 for me.
* src/keyboard.c (kbd_buffer_get_event): Re-enable SIGIO when waiting
for event.
