usually 80 chars) and thus question will be splitted into 2 consecutive lines.

However since the question is now refreshed every 2 secs, the reprinted
question will overwrite the second line of the previous one...

As long as nothing interferes with out output this logic will have no

However, if something is dumped in the middle, then our question won't
get lost, as we'll ask soon again.

This is useful if the question is asked to a terminal that is also

It merges the BindMount and TargetMount structures. They are mostly the same,
hence let's just use the same structue, and rely on C's implicit zero
initialization of partially initialized structures for the unneeded fields.

This reworks memory management of each entry a bit. It now contains one "const"
and one "malloc" path. We use the former whenever we can, but use the latter
when we have to, which is the case when we have to chase symlinks or prefix a
root directory. This means in the common case we don't actually need to
allocate any dynamic memory. To make this easy to use we add an accessor
function bind_mount_path() which retrieves the right path string from a
BindMount structure.

While we are at it, also permit "+" as prefix for dirs configured with
ReadOnlyPaths= and friends: if specified the root directory of the unit is
implicited prefixed.

This also drops set_bind_mount() and uses C99 structure initialization instead,
which I think is more readable and clarifies what is being done.

This drops append_protect_kernel_tunables() and
append_protect_kernel_modules() as append_static_mounts() is now simple enough
to be called directly.

Prefixing with the root dir is now done in an explicit step in
prefix_where_needed(). It will prepend the root directory on each entry that
doesn't have it prefixed yet. The latter is determined depending on an extra

Lennart Poettering [Tue, 15 Nov 2016 18:32:50 +0000 (19:32 +0100)]
core: GC redundant device jobs from the run queue

In contrast to all other unit types device units when queued just track
external state, they cannot effect state changes on their own. Hence unless a
client or other job waits for them there's no reason to keep them in the job
queue. This adds a concept of GC'ing jobs of this type as soon as no client or
other job waits for them anymore.

To ensure this works correctly we need to track which clients actually
reference a job (i.e. which ones enqueued it). Unfortunately that's pretty
nasty to do for direct connections, as sd_bus_track doesn't work for
them. For now, work around this, by simply remembering in a boolean that a job
was requested by a direct connection, and reset it when we notice the direct
connection is gone. This means the GC logic works fine, except that jobs are
not immediately removed when direct connections disconnect.

In the longer term, a rework of the bus logic should fix this properly. For now
this should be good enough, as GC works for fine all cases except this one, and
thus is a clear improvement over the previous behaviour.
