[pkg-gnupg-maint] Bug#801247: [gpg-agent] Env variables not available in some unknown cases

[aeris]

Package: gpg-agent

--- Please enter the report below this line. ---

Hi,

Seems not related to pinentry-gnome3 directly.
I use a custom pinentry python script (not using any gpg provided pinentry) to 
use kwallet, and I think I hit the same trouble.

Triggering pinentry invocation from shell (gpg) or desktop app (kmail), all is 
good. Triggering pinentry through gpg-agent ssh export, fails.

The difference in my case is env variable.

On the working case :
	LANG LISTEN_FDNAMES MANAGERPID SHELL XDG_RUNTIME_DIR JOURNAL_STREAM 
LISTEN_FDS LISTEN_PID XAUTHORITY LOGNAME USER PATH XMODIFIERS HOME 
GTK_IM_MODULE _assuan_pipe_connect_pid DBUS_SESSION_BUS_ADDRESS INVOCATION_ID
On the not working case :
	LANG LISTEN_FDNAMES MANAGERPID SHELL XDG_RUNTIME_DIR JOURNAL_STREAM 
LISTEN_FDS LISTEN_PID LOGNAME USER PATH HOME _assuan_pipe_connect_pid 
INVOCATION_ID

Missing between the two :
	XAUTHORITY XMODIFIERS GTK_IM_MODULE DBUS_SESSION_BUS_ADDRESS

Seems all X session related env variable are not propagated.

Pinentry is from the same gpg-agent, I don’t kill it between invocation.
There is trouble whatever the first call you do (shell/desktop or ssh), shell/
desktop always work even on a agent started with ssh and ssh always fail even 
on a shell/desktop started agent.

In my case, forcing manually the DBUS_SESSION_BUS_ADDRESS on my script resolve 
the trouble but ugly workaround (need to edit the script for each new 
session…). Without this variable, KWallet.Wallet.OpenWallet fails, perhaps the 
same thing happens with gnome wallet.

So, it’s seems something on gpg-agent which filter env variable based on an 
unknown criteria, probably related to X session.

As far I as know, I don’t faced this trouble some weeks ago with same 
configuration, so perhaps a regression somewhere. It works on my setup on 
2016-12-29.
I try to downgrade to gnupg 2.1.16-3 (used until 2017-01-04), but no more 
luck. This fact lets me to thing it’s perhaps not at all related to gnupg.

The process which run gpg-agent is systemd in my case.
	/lib/systemd/systemd --user
		\_ /usr/bin/dirmngr --supervised
		\_ /usr/bin/gpg-agent --supervised
