IMAP closing connection after inactivity

IMAP closing connection after inactivity

[Richard G Riley]

I have the same problem as the article I link and reproduce below. Is
there a way to get Gnus to keep an IMAP session open without using a
daemon to check for all new messages regularly?

http://osdir.com/ml/emacs.gnus.user/2006-02/msg00133.html

Same here...there is only line like:

"dovecot: 2008-01-31 08:50:38Info: IMAP(gour): Disconnected for
inactivity"

in dovecot's log.

Any workaround is appreciated...

Sincerely,
Gour

I received a reply (below) on the Dovecot mailing list. Could anyone here
suggest a Gnus fix?

Is your problem the same as described in the thread
<http://thread.gmane.org/8763y7e1ji.fsf@photon.caeruleus.net>?  Does
the patch suggested there (already included in current cvs) solve the
problem?

Bye, Reiner.

Yes, the problem seems to be the same.

I'll try to re-build my unicode-2 brancs tomorrow and will report back.

Make sure the it includes `imap-ping-server' in `imap.el'.  I'm not
sure how frequent Miles syncs from Gnus trunk -> Emacs trunk -> Emacs
unicode-2.

I jut pulled emacs-unicode-2 pkgbuild (Arch linux) and the patch is
there.

Emacs (&Gnus) are built....let's see now...

It does not help - connection to my localhost IMAP server died again:

Now I saw the following message in Gnus:

I have emacs-unicode-2 branch and it contains 'ping imap' patch, but
still...

It still closes on you too?

Are there any plans to re-investigate this?

I had a look at imap-ping-server but I dont know how to use it from a
demon or somesuch since it expects "buffer" to be an IMAP server. Not
being a lisp programmer I really don't quite know what that means or
expects.

Reiner, could you comment please?

(btw, I am using dovecot too and the developer said it is a Gnus issue
to keep the link alive).

Just a little "ping" here in case Reiner has missed the ongoing
issues. Where should one raise this matter further?

I -think- I'm seeing the same problem, despite having patched my
imap.el.

I'm running against cyrus, using 

GNU Emacs 22.1.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2008-01-30 on crepe
gnus 5.11

My apologies if I've missed a version bump somewhere; I've tried to
follow this thread.

Hi Reiner,

It solved the problem, thanks.

Q: why didn't this solve the problem? (I'm not a lisp programmer but it
seemed to be the right idea and the function was certainly polled every
10 minutes)

I still get:
