bug#1514: 23.0.60; Since some days (recentf-mode 1) fails with --daemon

[Tassilo Horn]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Here's a minimal test case:

  % emacs -Q --eval '(recentf-mode 1)' --daemon

The output is:

("emacs" "-Q" "--eval" "(recentf-mode 1)")
Starting Emacs daemon.
Loading /home/horn/.recentf...
Loading /home/horn/.recentf...done
Cleaning up the recentf list...
Loading tramp...
Wrong type argument: stringp, nil

If I omit the --daemon emacs starts up normally.  I have (recentf-mode
1) in my .emacs, and when starting emacs as daemon it'll stop evaluating
my init file after that line.

The change which breaks recentf-mode with --daemon has to be quite new.
At least a week ago --daemon worked fine with the same .emacs.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.60/etc/DEBUG for instructions.

No, I applied the patch but get the same error.

Do you have tramp files in your ~/.recentf?  I do and maybe that makes
the difference.

No, I deleted all tramp files from that file, but still It doesn't work.

--8<---------------cut here---------------start------------->8---
% emacs -Q --daemon --eval '(recentf-mode 1)'
("emacs" "-Q" "--eval" "(recentf-mode 1)")

--8<---------------cut here---------------end--------------->8---

So you see, it doesn't issue the tramp load message anymore, but still
it fails.  Judging from the output I'd say it fails in
`recentf-cleanup'.  But how can that be?  Looks like `recentf-list'
contains nil values, but I cannot find code that relies to a frame in
`recentf-mode', `recentf-load-list' or `recentf-cleanup'.  (Having no
initial frame is the main difference between emacs and emacs --daemon,
right?)

I did test that, yes.

In the latest CVS, I can't reproduce any problem. I tried with a
recentf file containing a mixture of existing and non-existing remote
and local files. (Previously, I did see your problem with remote
files).

Please try to narrow down your ~/.recentf file to the minimum needed
to cause the problem, then post it here if you don't mind.

In my last message I told you that I could reproduce the problem with a
recentf file with no tramp files.  That may not be true.  I deleted all
lines with "^\"/su.*" and didn't thing about "/ssh" and friends.

Sorry, I still can't reproduce any problem.

With a new emacs from yesterday evening (CET) I get (.recentf I postet
yesterday + some new entries):

--8<---------------cut here---------------start------------->8---
% emacs -Q --daemon --eval '(recentf-mode 1)'
("emacs" "-Q" "--eval" "(recentf-mode 1)")
Starting Emacs daemon.
Loading /home/horn/.recentf...
Loading /home/horn/.recentf...done

Cleaning up the recentf list...done (0 removed)
--8<---------------cut here---------------end--------------->8---

So it seems to start fine, but now emacsclient -c or emacsclient -t
return immediately without opening a frame.

But that has nothing to do with recentf; omitting the --eval results in
the same problem.  (I'll report a separate bug for the new issue and
suggest to keep this one open until I can check again with a functional
daemon/client.)

Ok, now emacsclient works again and the error I described in this bug
report has gone, too.
