From: Vitalie Spinu <spinuvit <at> gmail.com> To: 13475 <at> debbugs.gnu.org Subject: bug#13475: 24.2.91; accept-process-output hangs emacs on killed sub-process Date: Thu, 17 Jan 2013 13:21:25 +0100
Hi,
Accept-process-output, when run with WAIT argument, hangs emacs when the
underlying sub-process was killed. When WAIT is nil this problem does
not occur.
Start M-x shell and execute:
(let ((proc (get-process "shell")))
(process-send-string proc "sleep 60\n")
(while (not (accept-process-output proc .01))))
This puts emacs in a loop as expected. Now kill the bash process from
outside emacs and you will see that emacs is still hanged.
This problem does not occur when WAIT argument is nil. For example on
the execution of the following code, emacs successfully exits the waiting
loop after the bash process has been killed:
(let ((proc (get-process "shell")))
(accept-process-output proc))
Thanks,
Vitalie
