fish breaks dbus?

Samuel reports:

Hey RD.
Does you fork of fishfish have an issue with dbus? I just tried changing it to my default shell and it completely kills dbus in openSUSE.
otherwise it works fine without.

[ridiculousfish]

My speculation is that dbus assumes the default shell is POSIX compliant (i.e. /bin/sh).

Looks like this has been known for a long time...see http://marc.info/?l=freedesktop-dbus&m=117323277332615&w=2

I have the same situation in openSUSE and canNOT make fishfish as my default shell, but can start fishfish in bash after login

Axel gave them the patch six years ago, but it has yet to be integrated.

This seems pretty terrible, as unsophisticated users may be locked out of their machines. Let's see how hard this would be to hack around in fish.

[ridiculousfish]

Investingating more, I think the patch may not be sufficient. In /etc/X11/xdm/Xsession:

exec -l -a ${cmd} ${shell} -c 'exec "${@}"' - "${@}" ;;

No idea why this is being invoked in the login shell.

Anyways to support this current usage, we would need to:

1. Support the -c flag to mean "run the following arguments as commands"
2. Support the $@ (or more precisely, the ${@} variable, at least enough for this use case

[ridiculousfish]

I hacked up fish to support this exec usage when passed to -c, and it allows login on an openSUSE machine (!). This is true even with the dbus hacks disabled. Currently my changes are in the OpenSUSE_Hacks branch.

I'm going to email the dbus mailing list with questions about Axel's patch.

[ridiculousfish]

No reply after a week! The dbus mailing list appears dead.

I merged my hack - edb973f
Now we should no longer kill OpenSUSE
