I use several symmetrically encrypted files, like my ~/.authinfo.gpg
used by Gnus. That file is a symlink to
~/repos/configs/dot-authinfo.gpg. When I find it using emacs (started
with or without -Q), I have to give my password in a pinentry window,
then I have to accept following the symlink, and then I have to provide
the password a second time.

For information about GNU Emacs and the GNU system, type C-h C-a.
/home/horn/.authinfo: 0% (0/248)

Followed link to /home/horn/repos/configs/dot-authinfo.gpg
--8<---------------cut here---------------end--------------->8---
And although I have epa-file-cache-passphrase-for-symmetric-encryption
set to t, the passwords are not cached (epa-file-passphrase-alist is
nil). I've tried to edebug epa-file-passphrase-callback-function, but
I'm never put into the debugger. That function seems not to be
called...
That's a pretty serious issue for me, because since I entrypted my
.authinfo (which is good!), I have to enter my password for that file
gazillion times when starting up Gnus where I use 4 mail/news accounts
requiring authentication...

Hrm, I can't reproduce this. It seems that the only special thing on
your environment is that your dot-authinfo.gpg is version controlled.
However, even if I created a test Git repo and set up the symlink, I can
by-pass the 2nd password query, if
epa-file-cache-passphrase-for-symmetric-encryption is set.

Anyway, I added some resources to "(epa)Bug Reports". Could you provide
more information to reproduce this? Ideally, with a script to setup the
test environment. Here are the steps I tried:
$ mkdir -p /tmp/test && cd /tmp/test
$ gpg --symmetric > dot-test.gpg < /dev/null
$ git init
$ git add dot-test.gpg
$ cd .. && ln -s test/dot-test.gpg .test.gpg
$ emacs -Q
$ M-: (setq epa-file-cache-passphrase-for-symmetric-encryption t)
$ C-x C-f .test.gpg

Indeed, that's the cause of the issue. It has to be version controlled
and already committed (just git-added is not sufficient, but see below).

Sure.

Without having the file committed, emacs won't query you if it should
follow a symlink to a git version controlled file, and that seems to
trigger the bug.

Well that is my typo. Even if I commit the file, I'm asked for password
only once, while I'm actually asked if emacs should follow a symlink,
and I answer "yes".

Could you provide other hints (GnuPG version, etc)?

That's strange... After finding the file, should the file/password be
listed in `epa-file-passphrase-alist'? Here, it isn't...

I use gnupg-2.0.16, and there's also gpgme-1.3.0 installed, if that has
something to do with it.
I don't have any clue what additional info may be helpful...

Ah, you use gnupg2? Then, that is expected behavior. gnupg2 always use
gpg-agent and there is no way to intercept password from elisp level.
If you see your password is cached, that is probably because of my hack
in gpg-agent:
http://lists.gnupg.org/pipermail/gnupg-devel/2009-May/025045.html
Perhaps this patch does not work for symlinks.
Anyway I'd suggest to install gnupg1, which can coexist with gnupg2, and
(setq epg-gpg-program "path to gpg program from gnupg1")

Hm, passwords aren't cached in neither with nor without symlink. So I
guess that patch is not in my gnupg version.

Ok, then I'll do that.

FWIW, it has been available since gnupg-2.0.13 and I confirmed it with
Debian package based on 2.0.14. You can try it with:
$ echo aaa > test.txt
$ gpg2 --symmetric test.txt # will ask password twice
$ pkill -HUP gpg-agent # clear the password cache
$ gpg2 < test.txt.gpg # will ask password
$ gpg2 < test.txt.gpg # won't ask password
I personally think this feature safer than caching passwords in elisp.

Ah, I've just got you wrong. I've thought you hacked something up that
allows retrieving the passwords in elisp and cache them in the usual epa
variables. The caching in the agent works fine with the recipe above.
> I personally think this feature safer than caching passwords in elisp.
Yes, that's probably true.

Now I am wondering what is your problem. I tried the original recipe of
this bug with gnupg2 and I was asked password only once. Could you
provide other information in "(epa)Bug Reports"?

If it is usable :)

Nay, I was wrong. The gpg-agent (gnupg2) caching doesn't work for me,
too. When I do exactly that
--8<---------------cut here---------------start------------->8---
$ echo aaa > test.txt
$ gpg2 --symmetric test.txt
$ pkill -HUP gpg-agent
$ gpg2 < test.txt.gpg
$ gpg2 < test.txt.gpg
--8<---------------cut here---------------end--------------->8---
I'm queried twice for the password. Do I have to start gpg-agent with a
special option or edit my ~/.gnupg/gpg.conf?

Perhaps gpg-agent is not running on your X session at all? Check:
$ pgrep gpg-agent
2828
$ echo $GPG_AGENT_INFO
/tmp/gpg-Yy9vVW/S.gpg-agent:2828:1
If gpg-agent is not running in background, gpg2 will invoke gpg-agent
and kill it each time so gpg2 processes cannot share password cache per
session.

To set up gpg-agent, see "(gnupg) Invoking GPG-AGENT". BTW, on Debian,
gpg-agent will start automatically if you have "use-agent" in
~/.gnupg/gpg.conf (see /etc/X11/Xsession.d/*gpg-agent*).

I've explicitly started it before testing, but my error was that I
didn't source the agent info file.
> To set up gpg-agent, see "(gnupg) Invoking GPG-AGENT".
Great, I've went through that and set it up properly so that it gets
started the first time I login. And now it works on console and also
with emacs, with regular files and symlinks, and ditto for symlinks to
version controlled files.
Thanks a lot for being that patient with me. :-)
