Subject: Fixed OS X startup crash.
X-Git-Tag: emacs-25.0.90~1004
X-Git-Url: https://code.delx.au/gnu-emacs/commitdiff_plain/0392e241b844487261d4dfcccc9a442793e0a868

Fixed OS X startup crash.

Input events started to arrive before ns_term_init() was finished.
Solved by blocking input. This also seems to correct the "You
can't open the application "Emacs" because it may be damaged or
incomplete" error issued when double-clicking on the Emacs
application.

* nsterm.m (ns_constrain_all_frames, ns_init_term): Block input.
* nsterm.m (ns_send_appdefined, EmacsApp): Trace output.
