Buffer has a running process; kill it? (y or n)

[Leo]

Hello,

Gnus seems to ask this question a lot which is becoming annoying.

I suppose this happens when Gnus is talking to the server and the ssl
or whatever process is still running and at the same time you try to
exit Emacs.  I usually get this when I'm refreshing my group buffer
and try to exit Emacs or Gnus (I think) on NTemacs.

So, don't exit Emacs when you're doing something in Gnus.

I usually don't exit Emacs. It happens often when connection times out
i.e. when connection is ridiculously slow.

I am seeing this too, and this is always at startup. There seems to be
some imap process lingering but I have so far not tried to find out why
it is.

`(setq debug-on-quit t)', `C-g' when it asks, and post the resulting
backtrace.

I can't get any BT from this. It seems C-g is disabled in y-or-n-p.

How annoying.

I haven't had any similar reports -- could you be running some local
customisations that's killing buffers?

This seems to be related to Gnus killing buffers such as this one "
*server news.gmane.org nntp *nntpd**".

If you

`M-x debug-on-entry RET process-kill-buffer-query-function RET'

you'll probably get a backtrace the next time it asks.  Can you post
that backtrace?

I've seen this error on w32 emacs. It seems to be caused by recent
changes made to the error logging in the GnuTLS wrapper code. The
following fixed it for me:

(setq gnutls-log-level 2)

This restored some of the error message noise in the echo area, but
seems to stop issues being fatal errors.

HTH,

I advise process-kill-buffer-query-function to print the current buffer
and process when this happens and observe:

Warning (emacs): Process #<process nntpd> in buffer #<buffer  *server news.gmane.org nntp  *nntpd**>
Warning (emacs): Process #<process nntpd> in buffer #<buffer  *server news.gmane.org nntp  *nntpd**>
Warning (emacs): Process #<process nntpd> in buffer #<buffer  *server news.gmane.org nntp  *nntpd**>
Warning (emacs): Process #<process nntpd> in buffer #<buffer  *server news.gmane.org nntp  *nntpd**>
Warning (emacs): Process #<process nntpd> in buffer #<buffer  *server news.gmane.org nntp  *nntpd**>

I can then see that nntp-open-connection does not set
process-query-on-exit-flag which causes this warning.

Do you know if nntp-open-connection should do something like the
following?

  (set-process-query-on-exit-flag process nil)

`nntp-open-connection' does do that in bzr Emacs...

I am using upstream version. It doesn't always set that flag for example
when interrupted by C-g. In the Gnus in Emacs-23 I haven't seen such
problem.

Fixed now in git Gnus.

My solution

  kill-buffer-query-functions is a variable defined in `C source code'.
  Its value is (process-kill-buffer-query-function)

I set this variable to nil during startup using 

  gnus-before-startup-hook
  gnus-started-hook

because

  process-kill-buffer-query-function is a compiled Lisp function in
  `subr.el'.

  (process-kill-buffer-query-function)

  Ask before killing a buffer that has a running process.

But the point of raising it here is that something in Gnus doesn't set
up that variable correctly and has caused annoyance. It should be fixed
there.

It shouldn't be set by default.  I'm using eshell, for example, and I
/want/ to be informed when there are processes running I'm about to
kill.

Hi,

my solution is meant as workaround for the impatient.

The problem has been there for several month (since emacs-23 ?).

In my use case it seems to have to do with accessing two different IMAP
mail accounts / servers during startup.

When I regularly quit gnus and want to exit emacs, I'm told that still
two IMAP processes are running.

Cheers

Martin
