Subject: bug#1053: 23.0.60; 600 MB memory not freed after keyboard-quit
Date: Mon, 29 Sep 2008 21:20:00 +0200 [thread overview]
Message-ID: <b5accf970809291220h4520b569nfcc840cf1561aefc@mail.gmail.com> (raw)
Hi,
I am not sure if this is a real bug...
I run this function for ~1.5 hours without stopping:
(defun yyy (n k &optional tup)
(if (< 0 k)
(mapcar (lambda (x)
(when (or (null tup)
(> x (car (last tup))))
(yyy n (1- k) (append tup (list x)))))
(number-sequence 1 n))
;(message "%S" tup) <- yes, this was commented out
))
;; I started yyy this way:
(progn
(message "start: %s" (current-time-string))
(yyy 90 5)
(message "end: %s" (current-time-string)))
((I know mapc should be used above instead of mapcar; but think this
is a test program. It caused Emacs22 to give a "Warning! Memory limit
exceeded" on Windows2000 with 4GB memory, after running for ~20
minutes... -- now I tried to reproduce this on Linux with Emacs23 with
1 GB memory. The warning didn't come, but the following happened: ))
Emacs eat up all of the memory + a big chunk of the swap: Emacs itself
used ~620MB memory after 1.5 hours (not really increasing after some
time). Then I decided to stop it. Went to Emacs and typed C-g. Nothing
happened for a while, but after that buffer content was redrawn and I
could move the point (with the arroy keys): I thought yyy-process is
stopped and I can use Emacs again. But after a while Emacs again
stopped responding. Even the buffer content was not redrawn. I tried
C-g again and again, but nothing happened. I hoped just memory freeing
takes a long time, so left my PC for some minutes. This didn't helped
either. But after a while I could again use Emacs: killed the buffer
(containing yyy) and moved around the point just to see it works. But
memory still was occupied: Emacs used ~600MB. Later I killed Emacs
(with C-x C-c) and got back the memory.
I think Emacs should free the memory if I stop the process (with C-g)
what filled up the memory...at least after some minutes garbage
collection should work? Or is this behaviour described above a feature
of (keyboard-)quit?
Thanks,
P
