Escape unit names for the eval call in _call_program
The value of the Id property is transformed back into a unit name
usable by systemctl.
system-systemd\x5cx2dcryptsetup.slice -> system-systemd\x2dcryptsetup.slice
Also filter units by property via parameter expansion, not a for loop
After `journalctl -D /var/log/journal` "--directory", "--file",
"--machine" and "--root" should not be available for completion, because
they are exclusive. But multiple `--file` arguments are allowed.
In 68c4f6d the following was added:
local -a _modes; _modes=("--user" "--system")
local _sys_service_mgr=${${words:*_modes}[(R)(${(j.|.)_modes})]:---system}
With the following comment:
> If neither are on the line, --system is set; for system services to be
> completed.
But it does not work as documented:
% _modes=(--user --system)
% words=()
% echo ${${words:*_modes}[(R)(${(j.|.)_modes})]:---system}
However, it should not use `--system` in that case anyway, so this patch
removes the part that should cause a default to be used and adds some
comments.
This only completes fields from `journalctl --user` in _journal_fields when `--user`
is used.
It also changes $_sys_service_mgr to include both `--system` and `--user`,
because `journalctl` behaves different from `systemctl` in this regard.
No attempt is made to filter out invalid combinations, e.g. when using both
`--directory` and `--system` (see https://github.com/systemd/systemd/issues/3949).
This uses the same mechanism from _systemctl to inject `--user` into the
`journalctrl -F _EXE` call to list executables.
Before this patch the "commands" section would list executables from
system units always.
Use `$_sys_service_mgr` to handle `--user`, so that `systemctl --user
stop` will correctly filter the active (user) units. Before this patch,
only user units that also exist as system units and are stoppable there
would be listed.
This new output mode formats all timestamps using the usual format_timestamp()
call we use pretty much everywhere else. Timestamps formatted this way are some
ways more useful than traditional syslog timestamps as they include weekday,
month and timezone information, while not being much longer. They are also not
locale-dependent. The primary advantage however is that they may be passed
directly to journalctl's --since= and --until= switches as soon as #3869 is
merged.
While we are at it, let's also add "short-unix" to shell completion.
This patch renames Read{Write,Only}Directories= and InaccessibleDirectories=
to Read{Write,Only}Paths= and InaccessiblePaths=, previous names are kept
as aliases but they are not advertised in the documentation.
Renamed variables:
`read_write_dirs` --> `read_write_paths`
`read_only_dirs` --> `read_only_paths`
`inaccessible_dirs` --> `inaccessible_paths`
Support for net_cls.class_id through the NetClass= configuration directive
has been added in v227 in preparation for a per-unit packet filter mechanism.
However, it turns out the kernel people have decided to deprecate the net_cls
and net_prio controllers in v2. Tejun provides a comprehensive justification
for this in his commit, which has landed during the merge window for kernel
v4.5:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bd1060a1d671
As we're aiming for full support for the v2 cgroup hierarchy, we can no
longer support this feature. Userspace tool such as nftables are moving over
to setting rules that are specific to the full cgroup path of a task, which
obsoletes these controllers anyway.
This commit removes support for tweaking details in the net_cls controller,
but keeps the NetClass= directive around for legacy compatibility reasons.
But also keep the old name as (undocumented) compatibility around.
The reload-or-try-restart was documented to be a NOP if the unit is not running, since the previous commits this is
also implemented. The old name suggests that the "try" logic only applies to restarting. Fix this, by moving the "try-"
to the front, to indicate that the whole option is a NOP if the service isn't running.
Escape colons and backslashes in unit names.
This gives correct completions for units with names like
systemd-backlight@backlight:acpi_video0.service
and
systemd-fsck@dev-disk-by\x2duuid-...
The current code is not compatible with current dkr protocols anyway,
and dkr has a different focus ("microservices") than nspawn anyway
("whole machine containers"), hence drop support for it, we cannot
reasonably keep this up to date, and it creates the impression we'd
actually care for the microservices usecase.
This directive allows passing environment variables from the system
manager to spawned services. Variables in the system manager can be set
inside a container by passing `--set-env=...` options to systemd-spawn.
Tested with an on-disk test.service unit. Tested using multiple variable
names on a single line, with an empty setting to clear the current list
of variables, with non-existing variables.
Tested using `systemd-run -p PassEnvironment=VARNAME` to confirm it
works with transient units.
Confirmed that `systemctl show` will display the PassEnvironment
settings.
Checked that man pages are generated correctly.
No regressions in `make check`.
Snapshots were never useful or used for anything. Many systemd
developers that I spoke to at systemd.conf2015, didn't even know they
existed, so it is fairly safe to assume that this type can be deleted
without harm.
The fundamental problem with snapshots is that the state of the system
is dynamic, devices come and go, users log in and out, timers fire...
and restoring all units to some state from the past would "undo"
those changes, which isn't really possible.
Tested by creating a snapshot, running the new binary, and checking
that the transition did not cause errors, and the snapshot is gone,
and snapshots cannot be created anymore.
New systemctl says:
Unknown operation snapshot.
Old systemctl says:
Failed to create snapshot: Support for snapshots has been removed.
IgnoreOnSnaphost settings are warned about and ignored:
Support for option IgnoreOnSnapshot= has been removed and it is ignored

'set-property' was missing from the list of known command.
Also a list of unit names will be proposed as next argument.
However no support on property names is provided since it would
require a hard coded list of them.
