Package: gnupg-agent
Version: 2.0.18-2
Severity: important
(This bug should perhaps be filed against both gnupg and gnupg2, but
debbug doesn't really have a clean way to do this, so...)
I expect you're aware that when gpg or gpg2 is invoked under Emacs, the
DISPLAY environment variable is unset, and gpg-agent needs to prompt for
a passphrase, the pinentry program makes a mess on the terminal.
It might not be fair to blame this on pinentry or gpg-agent, though
gpg-agent could perhaps discard any "ttyname" values accompanied by a
"ttytype" of "dumb", if the following excerpt from an strace of
gpg-connect-agent run using Emacs' `shell-command' is any indication:
,----
| socket(PF_FILE, SOCK_STREAM, 0) = 4
| connect(4, {sa_family=AF_FILE, path="/home/naesten/.gnupg/S.gpg-agent"}, 34)
= 0
| read(4, "OK Pleased to meet you, process "..., 1002) = 38
| write(4, "RESET", 5) = 5
| write(4, "\n", 1) = 1
| read(4, "OK\n", 1002) = 3
| write(4, "OPTION ttyname=/dev/pts/38", 26) = 26
| write(4, "\n", 1) = 1
| read(4, "OK\n", 1002) = 3
| write(4, "OPTION ttytype=dumb", 19) = 19
| write(4, "\n", 1) = 1
| read(4, "OK\n", 1002) = 3
| write(4, "OPTION lc-ctype=en_US.UTF-8", 27) = 27
| write(4, "\n", 1) = 1
| read(4, "OK\n", 1002) = 3
| write(4, "OPTION lc-messages=en_US.UTF-8", 30) = 30
| write(4, "\n", 1) = 1
| read(4, "OK\n", 1002) = 3
`----
Alternatively, gnupg/gnupg2/et al could refrain from sending the tty at
all in such cases. I believe most of these programs use a library to
communicate with gpg-agent; perhaps the logic could be added there?
