Subject: bug#65193: 29.1.50; SET_FRAME_ICONIFIED can cause Lisp evaluation inside read_socket_hook.
Date: Fri, 11 Aug 2023 01:33:41 +0900 [thread overview]
Message-ID: <wlcyzuamca.wl-mituharu@math.s.chiba-u.ac.jp> (raw)
In-Reply-To: <87zg2zqcbg.fsf@yahoo.com>
Another problem specific to the NS port w.r.t. the call to
gui_consider_frame_title from SET_FRAME_ICONIFIED is that it can
also be called inside the select emulation via -[EmacsView
windowDidDeminiaturize:] for example.
With multiple Lisp threads, select causes thread switching. So, Lisp
evaluations can simultaneously happen both on the main thread (via
-[EmacsView windowDidDeminiaturize:]) and on another Lisp thread.
This breaks the cooperative nature of the Emacs threads.
