The usage of PREFIX in this completion is mostly counter to the intended
usage of compsys in zsh. It is generally expected that completion code
provide the available completions and tags in that word position so that
compsys, with user configuration, can filter them to the appropriate set.
One egregious error caused by the usage of PREFIX here is the caching of
SYS_ALL_UNITS, which stored only the unit names prematurely filtered by
the completion prefix, affecting all future completions. For example,
$ systemctl cat nonsense<TAB>
might find no matching units if nonsense* has no matches, but now
$ systemctl cat <TAB>
will fail in all future completions even though every unit file
is a valid match, because the cached set has been erroneously filtered
by the last prefix.
getopt allows non-ambiguous abbreviations, so backwards-compat is maintained, and
people can use --kill-who (or even shorter abbreviations). English is flexible,
so in common speach people would use both forms, even if "whom" is technically
more correct. The advantage of using the longer form in the code is that we
effectively allow both forms, so we stop punishing people who DTGCT¹, but still
allow people to use the spoken form if they prefer.
1. Do the gramatically correct thing
I don't think it makes sense to complete --legend=yes. It is the default, and
it would be only used very rarely (and then it is easy enough to just remove
the '=no' part from the suggested string).
Allow to setup new bind mounts for a service at runtime (via either
DBUS or a new 'systemctl bind' verb) with a new helper that forks into
the unit's mount namespace.
Add a new integration test to cover this.
Useful for zero-downtime addition to services that are running inside
mount namespaces, especially when using RootImage/RootDirectory.
If a service runs with a read-only root, a tmpfs is added on /run
to ensure we can create the airlock directory for incoming mounts
under /run/host/incoming.
As described in #2680, systemctl did ignore inhibitors if it is not
attached to a tty to allow scripts to ignore inhibitors automatically.
This pull request preserves this behavior but allows scripts to
explicit check inhibitors if required.
The new parameter '--check-inhibitors=yes' enables this feature.
The old parameter '-i'/'--ignore-inhibitors' was deprecated in favor
of '--check-inhibitors=no', the default behaviour can be specified
with '--check-inhibitors=auto'.
The new parameter is also described in the documentations and shell
completions found here.
unset-environment is completed with variable names in the environment block.
set-environment the same, but suffixed with "=".
import-environment is completed with variable names in the client environment.
Timestamps for unit start/stop are recorded with microsecond granularity,
but status and show truncate to second granularity by default.
Add a --timestamp=pretty|us|utc option to allow including the microseconds
or to use the UTC TZ to all timestamps printed by systemctl.
The "preset" column introduced in
b01c1f305c breaks zsh completion for
systemctl disable/enable. Fix by ignoring everything after the last
space in a line.
Hiding the first column, which may contain bullet circles, with --no-legend
is undocumented and potentially unexpected. On the other hand, not printing
bullet circles with --plain is documented so hiding the column with that
switch is sensible.
The combination "--full --no-legend --no-pager --plain" is appropriate for
automated processing of systemctl output.
