running gpg-agent in foreground

Post #1 of 3 (82 views)

I would like to run my development version of GPG-agent under valgrind.
As I understand it, for that purpose I have to run it in the foreground,
i.e. in server mode. However, whenever I launch it as

./bin/gpg-agent --homedir <my-gpg-home-dir> --log-file agent.log
--server --debug-all

then, when I launch a private key operation via the gpg application, a
new agent is started (in daemon mode) and used by gpg and I find no way
to get the agent launched in server mode to ever process anything.

In contrast, if I start it with the same command line, except for using
daemon mode, i.e.,

./bin/gpg-agent --homedir <my-gpg-home-dir> --log-file agent.log
--daemon --debug-all

then the gpg application always connects to it like expected.

Any ideas how I can launch the agent in the foreground so that the gpg
application will connect to it?

No, that will not work for you. I recommend this:

cd /my/test/directory
GNUPGHOME=`pwd` gpg-agent --daemon /bin/sh

This way you can easily start gpg-agent via valgrind. Instead of
running a shell directly you may also use a script instead of /bin/sh:

--8<---------------cut here---------------start------------->8---
#!/bin/sh

SSH_AUTH_SOCK=$(gpgconf --list-dirs agent-ssh-socket)
export SSH_AUTH_SOCK
cat >setup-tests.ini <<'EOF'
PS1="$(echo "$PS1" | sed 's,\\\$ $,(GnuPGTest)\\\$ ,')"
export HISTCONTROL=ignoreboth
export HISTFILE=$(pwd)/.bash_history
EOF
exec bash --init-file setup-tests.ini
--8<---------------cut here---------------end--------------->8---

which gives you a dedicated prompt so that you can easily see that you
are in a test environment.

For logging put "log-file socket://" into common.conf and
run

watchgnupg --time-only --homedir /my/test/directory

in another terminal. Add --force to take over the logging socket.
Useful debug options for gpg-agent.conf are "debug ipc". Use
"gpg-agent --debug help" to get a list of all debug options.

Thanks, the first approach seems to work fine for me.
