By default, the available completions are sorted alphabetically, which
is counterproductive in case of syslog priorities. Override the default
behavior using the `nosort` option
The option cursor-file takes a filename as argument. If the file exists and
contains a valid cursor, this is used to start the output after this position.
At the end, the last cursor gets written to the file.
This allows for an easy implementation of a timer that regularly looks in the
journal for some messages.
journalctl --cursor-file err-cursor -b -p err
journalctl --cursor-file audit-cursor -t audit --grep DENIED
Or you might want to walk the journal in steps of 10 messages:
journalctl --cursor-file ./curs -n10 --since=today -t systemd
- Don't redefine helpers on every call
- Prefix helper names with main function name
- Adjust some helper names for consistency and convention adherance
This way external commands (i.e. executables in the PATH) are suggested
at --debugger=<TAB>. Upon starting a path (e.g. --debugger=/<TAB> or
--debugger=./<TAB>), filenames of executables are completed.
Also, while we are at it, beef it up, by adding json-seq support (i.e.
https://tools.ietf.org/html/rfc7464). This is particularly useful in
conjunction with jq's --seq switch.
This also unifies __filter_units_by_property() and
__filter_units_by_properties(), and makes completion for 'restart',
'reload' or 'stop' show more candidates.
Usecase is to allow changing the final kill from SIGKILL to SIGQUIT which
should create a core dump useful for debugging why the service didn't stop
with the SIGTERM
Currently the completion adds template units for commands such as
is-active, is-failed, is-enabled, status, show and others.
At the same time systemctl barfs at us, since an instanced template unit
is needed. Follow the example list from bash-completion as to which
commands should not list template units.
Note: The above is observed regardless of DefaultInstance.

Template units lacking DefaultInstance cannot be enabled/disabled or
started/restarted.
By adding DefaultInstance the unit can be enabled/disabled but it
still cannot be started/restarted.

Earlier patch added the current word to the performance critical paths.
Here we add it to every place, for consistency sake.

This effectively ports over b1bdb6496c
from the bash completion to zsh.
Modulo the new function, since it's unrelated perf. improvement.

Using a leading * and $SUFFIX produces misleading results. Let's imagine
that one mistypes nect instead of netc, they will get a rather
misleading completion like: sys-fs-fuse-connections.mount
Not to mention that the execution time is up by ~1/3.
time systemctl list-unit-files netctl* -> ~12ms
time systemctl list-unit-files *netctl* -> ~17ms
Furthermore more units are matched, leading to greater execution time
of `systemctl show' in _filter_units_by_property
Use only $PREFIX*, removing the leading * and trailing $SUFFIX*.

Pass the partial name of the unit file to list-unit-files and
list-units. This allows for faster completion, since systemctl does
not need to list all the unit files.
For reference:
- time systemctl list-unit-files -> ~200ms
- time systemctl list-unit-files netctl* -> ~15ms
- time systemctl list-units -> ~5ms
- time systemctl list-units netctl* -> ~5ms
While the list-units time itself is unaffected, now a shorter list is
produced. Thus as we pass it to `systemctl show' (via
__filter_units_by_properties) the execution time will be decreased even
further.
v2: Update list-units hunk in commit message, add quotes around $2*
v3: Remove funky indentation, quote all $cur instances

When dealing with a large number of template instances, for example
when launching daemons per VRF, it is hard for operators to correlate
log lines to arguments.
Add a new with-unit mode which, if available, prefixes unit and user
unit names when displaying its log messages instead of the syslog
identifier. It will also use the full timestamp with timezones, like
the short-full mode.
If completion is attempted on an invalid path, busctl might respond with an error.
This shouldn't be seen, introspection is supposed to just fail silently.
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.
Suspend to Hibernate is a new sleep method that invokes suspend
for a predefined period of time before automatically waking up
and hibernating the system.
It's similar to HybridSleep however there isn't a performance
impact on every suspend cycle.
It's intended to use with systems that may have a higher power
drain in their supported suspend states to prevent battery and
data loss over an extended suspend cycle.

That way, they're always sorted by date. I do not know how to make ZSH sort
them by PID through some option, but that doesn't seem very useful in the first
place.
An output from coredumpctl list is like
> TIME PID UID GID SIG COREFILE EXE
> Sun 2016-05-29 18:44:03 CEST 14578 1000 1000 6 none /tmp/pacaurtmp-wieland/python33/src/Python-3.3.6/python
^1 ^2 ^3 ^4 ^5
, but the previous sub() command turns that into
> TIMEPID UID GID SIG COREFILE EXE
> Sun2016-05-29 18:44:03 CEST 14578 1000 1000 6 none /tmp/pacaurtmp-wieland/python33/src/Python-3.3.6/python
^1 ^2 ^3 ^4 ^5
so the whole pipeline generated entries like
$UID:$DESCRIPTION
but that's not useful and probably not what was supposed to happen.
This now generates entries like
$PID:$DESCRIPTION
which make everything work.
Note that with this commmit, the completions will be sorted by PID by
ZSH.
