Common, don't flip flop on that one. All the programs have an insane
amount of initialization boilerplate, and your patch reduces that a tiny
bit, by moving some initialization of a common subsystem that happens
everywhere to 'init_common_subsystem', which sounds perfectly
Also, xmpp is nice, but the discussion is already lost to history, so
let's quickly recap the potential problems, and then have a proper
I remember three things, 1/ the order of includes may be important, 2/
some magical way that the error source is set that your change may have
changed accidentally, 3/ i18n.h being included in common/init.c being a
problem, 4/ init_common_subsystems might be running as root.
Did I miss anything?
1/ If the order is important, I don't like that, and we should fix
that. That sounds like the code is trying to be clever with the
2/ Likewise. It might be convenient, but it sounds too magical to be
good. Explicit is better than implicit.
3/ I don't understand that point at all.
4/ Is that actually a problem? I just checked, none of the gnupg
components on my Debian/Linux system are suid root, so that could only
be the case if one runs gnupg as root, and I don't see why we should/how
we could protect the user in this case, or it is not run as root in the
first place, and then this point is moot.
I believe that the change we merged looks very reasonable (hence I
merged it), and such a change should not be able to have subtle
side-effects like the ones Werner fears. If there are weird implicit
side-effects, I believe we should make sure that such side-effects
cannot happen instead of reverting that change.
