core: fix confusing logging of instantaneous jobs

For instantaneous jobs (e.g. starting of targets, sockets, slices, or
Type=simple services) the log shows the job completion
before starting:

        systemd[1]: Created slice -.slice.
        systemd[1]: Starting -.slice.
        systemd[1]: Created slice System Slice.
        systemd[1]: Starting System Slice.
        systemd[1]: Listening on Journal Audit Socket.
        systemd[1]: Starting Journal Audit Socket.
        systemd[1]: Reached target Timers.
        systemd[1]: Starting Timers.
        ...

The reason is that the job completes before the ->start() method returns
and only then does unit_start() print the "Starting ..." message.
The same thing happens when stopping units.

Rather than fixing the order of the messages, let's just not emit the
Starting/Stopping message at all when the job completes instantaneously.
The job completion message is sufficient in this case.

Our seat->positions[] array keeps track of the 'preferred' session on a

when a VT is activated. In the normal case, there's only one session per
VT so the selection is trivial.

Older greeters, however, implement take-overs when they start sessions on
the same VT that the greeter ran on. We recently limited such take-overs
to VTs where a greeter is running on, to force people to never share VTs
in new code that is written.

For legacy reasons, we need to be compatible to old greeters, though.
Hence, we allow those greeters to implement take-over. In such take-overs,
however, we should really make sure that the new sessions gets preferred
over the old one under all circumstances. Hence, make sure we override
the previous preferred session with a new session.

9 years agosd-bus: fix gvariant structure encoding
David Herrmann [Thu, 16 Jul 2015 09:00:55 +0000 (11:00 +0200)]
sd-bus: fix gvariant structure encoding

In gvariant, all fixed-size objects need to be sized a multiple of their
alignment. If a structure has only fixed-size members, it is required to
be fixed size itself. If you imagine a structure like (ty), you have an
8-byte member followed by an 1-byte member. Hence, the overall inner-size
is 9. The alignment of the object is 8, though. Therefore, the specs
mandates final padding after fixed-size structures, to make sure it's
sized a multiple of its alignment (=> 16).

On the gvariant decoder side, we already account for this in
bus_gvariant_get_size(), as we apply overall padding to the size of the
structure. Therefore, our decoder correctly skips such final padding when
parsing fixed-size structure.

On the gvariant encoder side, however, we don't account for this final
padding. This patch fixes the structure and dict-entry encoders to
properly place such padding at the end of non-uniform fixed-size
structures.

The problem can be easily seen by running:
    $ busctl --user monitor
and
    $ busctl call --user org.freedesktop.systemd1 / org.foobar foobar "(ty)" 777 8

The monitor will fail to parse the message and print an error. With this
patch applied, everything works fine again.

This patch also adds a bunch of test-cases to force non-uniform
structures with non-pre-aligned positions.

Thanks to Jan Alexander Steffens <jan.steffens@gmail.com> for spotting
this and narrowing it down to non-uniform gvariant structures. Fixes #597.
