Subject: bug#24553: 25.1; epa ignores epg-gpg-program in very confusing way
Date: Tue, 27 Sep 2016 01:15:40 -0700 [thread overview]
Message-ID: <87twd1ep1v.fsf@ta.scs.stanford.edu> (raw)
I need to edit some files that decrypt properly with gpg 1.4 but not gpg
2.1. I have both installed on my system, with 1.4 as /usr/bin/gpg1 and
2.1 as /usr/bin/gpg2. The bug is that emacs ignores the epg-gpg-program
variable *except* in error messages, which is very confusing. To
reproduce this problem, do the following:
* Run strace -o /tmp/log emacs -Q
* Eval expression (setq epg-gpg-program "/usr/bin/gpg1")
* Open a gpg-encrypted file
By examining /tmp/log, or running ps, you can see that emacs is
executing a command like the following:
/usr/bin/gpg2 --no-tty --status-fd 1 --yes --enable-progress-filter --command-fd 0 --output /tmp/epg-output6602ygi --decrypt -- /tmp/x.gpg
However, when it fails to decrypt, it prints the message: Error while
decrypting with "/usr/bin/gpg1." This is obviously very frustrating
since gpg1 can in fact decrypt the file. Ideally emacs should obey
epg-gpg-program, but if it doesn't, it should properly report what
failed.
