emacs -batch -l ~/.emacs -f gnus-agent-batch

Hello.

This command could not be run for imap backend without controlling
terminal:
11:39 pts/0 sacha@pale:~ 41> emacs -batch -l ~/.emacs -f gnus-agent-batch </dev/null
imap: Connecting to giotto.sj.ru...
imap: Opening IMAP connection with `ssh -q %s /usr/sbin/imapd'...
zsh: hangup     emacs -batch -l ~/.emacs -f gnus-agent-batch < /dev/null

Can you run this command from the shell with no controlling terminal?

Actually, I do not understand the question.

I am able to run the command throm shell. But I am not able to run it,
for instance, with cron. Simple way to replroduce the problem is to
put /dev/null on the command's stdin while running it from shell.

Yes, I meant whether it is possible to run

    ssh -q %s /usr/sbin/imapd </dev/null
                              ^^^^^^^^^^

I underlined the important part, and the %s needs to be replaced with
something else, of course.

Now here is my reasoning:

It does not work to let "ssh -q ... /usr/sbin/imapd" read from
/dev/null, probably because the command needs some input.  The need
for input doesn't go away by letting it run under Emacs, so you
shouldn't be surprised that letting Emacs (and thus, sshd) read from
/dev/null doesn't work, either.

Or am I misunderstanding something?

Hm... I think something is wrong here. emacs/gnus should read not the
input on console, but the output of ssh -q %s /usr/sbin/imapd. The
latter command do not want any input, since ssh auth is made via keys.

So "ssh -q %s /usr/sbin/imapd </dev/null" (including the redirection)
works, when invoked outside of Emacs?

If you invoke "emacs -batch -l ~/.emacs -f gnus-agent-batch" without
the redirection, what kind of input is expected from stdin?

Does this patch together with frobing `imap-process-connection-type'
help?  (Line numbers might differ, it is in `imap-shell-open'.)

It does not. imap-process-connection-type is t.

It should not, since gnus would like to pass some commands to _imapd_
instead of /dev/null, while I am not going to pass anything to 
emacs -f gnus-agent-batch

KG> If you invoke "emacs -batch -l ~/.emacs -f gnus-agent-batch" without

I never type anything ot emacs when it evaluates gnus-agent-batch.
gnus-agent-synchronize-flags is t (means 'always sync flags').

What if you set it to nil?

Is flag synchronizing performed from gnus-agent-batch?

Even if it isn't, your scenario should work though, as the gnus at
work should update its flags.

Yes and no. The command always prints something like 

Checking new news...done
nnimap: Setting marks in IMAP/ding...
nnimap: Setting marks in IMAP/ding...done
Finished fetching articles into the Gnus agent

But I've never seen it writing lines about getting flags from server.

No "Updating info for ..." messages?

If so, that explains it; the agent fails to call nnimap-request-group.
But `gnus-agent-fetch-group-1' seem to call it (via gnus-activate).
Hm.  Could you perhaps edebug the function to see what goes wrong?

Ah, good point.  Sorry for that bogus question.

What happens if you call Emacs normally (without "-batch"), then do
M-: (gnus-agent-batch) RET?  Does it work?  Does it ask for any input?

Does it work to "emacs -batch -l ~/.emacs -f gnus-agent-batch"
without the redirection?
