Hi all,
since about one or two months, Gnus frequently hangs when retrieving new
mail from Gmail. I use demons checking for new mail every few minutes
of idle time.
--8<---------------cut here---------------start------------->8---
(add-to-list 'gnus-secondary-select-methods
'(nnimap "Gmail"
(nnimap-address "imap.gmail.com")))
(require 'gnus-demon)
(gnus-demon-add-handler 'gnus-demon-scan-news 15 5)
--8<---------------cut here---------------end--------------->8---
When Gnus hangs, *Messages* shows:
20130625T141848.814> nnimap read 0k from imap.gmail.com
I can easily hit `C-g' to quit, and then a `g' will usually work fine
again. I also use two other IMAP accounts, but this problem seems to
occur only with Gmail.
Is there anyone else encountering this problem? And how can I diagnose
what's the culprit?
After such a hang, I've checked the " *nnimap imap.gmail.com nil
*nntpd**" buffer. It contained
--8<---------------cut here---------------start------------->8---
...
* 1201 FETCH (UID 2637 FLAGS (%Seen))
* 1202 FETCH (UID 2638 FLAGS (%Seen))
* 1203 FETCH (UID 2640 FLAGS (%Seen))
2498 OK Success
--8<---------------cut here---------------end--------------->8---
which doesn't look as if it stalled during doing IMAP stuff, so I guess
the problem is somewhere in initiating a connection to Gmail...
Bye,
Tassilo

Yes, exactly as you describe. I can tell almost immediately when it's
about to hang and I just do as you do: hit C-g, then g and it works
fine.

I've been getting this for much more than 2 months. It also depends on
where I am (at work, it doesn't happen; at home, all the
time). Something that helps a bit is this:
;; This function is hooked into gnus-get-new-news-hook and
;; gnus-summary-exit-hook in order to prevent hangs. Sometimes, Emacs doesn't
;; notice that the connection is lost.
(defun dvl-gnus-kill-server-connections ()
"Kill Gnus server connections.
See also the variable `dvl-gnus-kill-server-connections'."
(when dvl-gnus-kill-server-connections
(call-process "killall" nil nil nil "gnutls-cli")))
But it's definitely not enough to make the problem go away. I also have
other sorts of hangs all over the place (related to nntp backends
notably) and I have to C-g g up to 3 or 4 times in a row sometimes.

For me, it happens at work, at home, and lately I've traveled to
Budapest where it also happened both from the hotel as well as the
university.

I've compiled emacs with gnutls support, so no external gnutls-cli will
be spawned when making a connection (I think). At least
% while true; do ps -e | grep gnutls; done
doesn't generate any output when closing and re-opening a connection
from the server buffer, or when checking for new mail with `g'.

Lately I also faced similar issue and I decided to move over to
offlineimap+dovecot setup.

+1. Usually I have to hit C-g a bunch of times (once for every backend?
for every mailbox?).
I can almost be sure it'll hang after waking up my laptop from
powersafe. This has been an issue since, about, forever :)

Well, yes. After waking up my computer, it'll hang with any account.
But when it is running and a network connection is there, it's always
only my gmail account that hangs. I hit C-g to stop it, and then it'll
successfully check the accounts that come after gmail in my secondary
select methods.

FWIW I've seen this as well, but when I go unplugged before sleeping the
computer and then go plugged again, after waking the computer, possibly
in a different network, I do not see the issue.
My non-agentized and non-local servers tends to go Offline by this
practice, though. I may have to enter the server buffer and open them
manually. But after that, the operation seems to be normal.

It seems I've been wrong. Although the message above suggests its a
gmail problem, hitting C-g with debug-on-error set to t, I get such a
backtrace that tells me that we're actually hanging while getting new
news from the nntp server news.eclipse.org.

Since I don't need to read groups from that server anymore, I've just
removed it and the hangs seem to be gone.
Well, still it would be nice if there was some sensible way for dealing
with unresponsive servers, e.g., like aborting after some seconds. My
main problem with the hangs was that IRC servers to that I've been
connected using rcirc disconnect after some time if they cannot contact
the client anymore. So if I didn't notice the hang, chances were high I
got accidentally kicked out of my running IRC sessions.

Yes, if that's what's going on here. There was a problem with
`nntp-finish-retrieve-group-infos' earlier that was really hard to
debug, but I thought I had gotten it right eventually.
The problem is that Gnus issues lots of commands to different servers,
and then waits for the response from them all. This parallelism makes
things faster, but if Gnus somehow thinks that two different servers are
the same, things kinda blow up.
Does Gnus hang this way frequently? In that case, it's probably Gnus'
fault, and not really a hanging server.
If it happens very infrequently, then it may be a hanging server...
