From: Spencer Baugh <sbaugh <at> janestreet.com> To: 67046 <at> debbugs.gnu.org Subject: bug#67046: 29.1.50; map-y-or-n-p infinite loops if it's at the end of a kmacro Date: Fri, 10 Nov 2023 11:43:25 -0500
For example, if you record a kmacro which does C-x s, then when you
repeat the kmacro and there are more buffers which could be saved, the
kmacro will hang instead of either completing or erroring.
Straightforward minimal reproduction:
(execute-kbd-macro (kbd "M-: (map-y-or-n-p SPC \"\" SPC #'ignore SPC '(1)) RET"))
This hangs in a loop around read-event and has to be interrupted with C-g.
The loop in question in map-y-or-n-p:
(while (progn
(setq char (read-event))
;; If we get -1, from end of keyboard
;; macro, try again.
(equal char -1)))
I'll fix this in a followup patch.
