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.
Apparently both Fedora and suse default to btrfs now, it should hence be
good enough for us too.
This enables a bunch of really nice things for us, most importanly we
can resize home directories freely (i.e. both grow *and* shrink) while
online. It also allows us to add nice subvolume based home directory
snapshotting later on.
Also, whenever we mention the three supported types, alaways mention
them in alphabetical order, which is also our new order of preference.
Since cryptsetup 2.3.0 a new API to verify dm-verity volumes by a
pkcs7 signature, with the public key in the kernel keyring,
is available. Use it if libcryptsetup supports it.
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.
Add shortcuts to enable and start, or disable and stop, portable
services with a single portablectl command.
Allow to pass a filter on detach, as it's necessary to call
GetImageMetadata to get the unit names associated with an image.
Fixes#10232
v2:
- if RestartKillSignal= is not specified, fall back to KillSignal=. This is necessary
to preserve backwards compatibility (and keep KillSignal= generally useful).
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
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
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.

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.

So far I avoided adding license headers to meson files, but they are pretty
big and important and should carry license headers like everything else.
I added my own copyright, even though other people modified those files too.
But this is mostly symbolic, so I hope that's OK.
The configuration option was called -Dresolve, but the internal define
was …RESOLVED. This options governs more than just resolved itself, so
let's settle on the version without "d".
The advantage is that is the name is mispellt, cpp will warn us.

squash! build-sys: use #if Y instead of #ifdef Y everywhere
v2:
- fix incorrect setting of HAVE_LIBIDN2
They’re counterparts to the existing set-log-level and set-log-target
verbs, simply printing the current value to stdout. This makes it
slightly easier to temporarily change the log level and/or target and
then restore the old value(s).
Without this fix:
$ systemctl start <tab>
Display all 135 possibilities? (y or n)
$ __get_startable_units --system | wc -l
224
the number of the suggestions are quite different, as __get_startable_units --system does
not filter already started units. With this fix,
$ systemctl start <tab>
Display all 135 possibilities? (y or n)
$ __get_startable_units --system | wc -l
123
$ __get_template_names --system | wc -l
12
the number of the suggestions matches one the function returns.
For consistency with the other internal functions, it should use the first argument
instead of the global variable $mode.
[zj: add commit message to make it sound like we know what we're doing]
Using conf.set() with a boolean argument does the right thing:
either #ifdef or #undef. This means that conf.set can be used unconditionally.
Previously I used '1' as the placeholder value, and that needs to be changed to
'true' for consistency (under meson 1 cannot be used in boolean context). All
checks need to be adjusted.
The indentation for emacs'es meson-mode is added .dir-locals.
All files are reindented automatically, using the lasest meson-mode from git.
Indentation should now be fairly consistent.
It's crucial that we can build systemd using VS2010!
... er, wait, no, that's not the official reason. We need to shed old systems
by requring python 3! Oh, no, it's something else. Maybe we need to throw out
345 years of knowlege accumulated in autotools? Whatever, this new thing is
cool and shiny, let's use it.
This is not complete, I'm throwing it out here for your amusement and critique.
- rules for sd-boot are missing. Those might be quite complicated.
- rules for tests are missing too. Those are probably quite simple and
repetitive, but there's lots of them.
- it's likely that I didn't get all the conditions right, I only tested "full"
compilation where most deps are provided and nothing is disabled.
- busname.target and all .busname units are skipped on purpose.
Otherwise, installation into $DESTDIR has the same list of files and the
autoconf install, except for .la files.
It'd be great if people had a careful look at all the library linking options.
I added stuff until things compiled, and in the end there's much less linking
then in the old system. But it seems that there's still a lot of unnecessary
deps.
meson has a `shared_module` statement, which sounds like something appropriate
for our nss and pam modules. Unfortunately, I couldn't get it to work. For the
nss modules, we need an .so version of '2', but `shared_module` disallows the
version argument. For the pam module, it also didn't work, I forgot the reason.
The handling of .m4 and .in and .m4.in files is rather awkward. It's likely
that this could be simplified. If make support is ever dropped, I think it'd
make sense to switch to a different templating system so that two different
languages and not required, which would make everything simpler yet.
v2:
- use get_pkgconfig_variable
- use sh not bash
- use add_project_arguments
v3:
- drop required:true and fix progs/prog typo
v4:
- use find_library('bz2')
- add TTY_GID definition
- define __SANE_USERSPACE_TYPES__
- use join_paths(prefix, ...) is used on all paths to make them all absolute
v5:
- replace all declare_dependency's with []
- add more conf.get guards around optional components
v6:
- drop -pipe, -Wall which are the default in meson
- use compiler.has_function() and compiler.has_header_symbol instead of the
hand-rolled checks.
- fix duplication in 'liblibsystemd' library name
- use the right .sym file for pam_systemd
- rename 'compiler' to 'cc': shorter, and more idiomatic.
v7:
- use ENABLE_ENVIRONMENT_D not HAVE_ENVIRONMENT_D
- rename prefix to prefixdir, rootprefix to rootprefixdir
("prefix" is too common of a name and too easy to overwrite by mistake)
- wrap more stuff with conf.get('ENABLE...') == 1
- use rootprefix=='/' and rootbindir as install_dir, to fix paths under
split-usr==true.
v8:
- use .split() also for src/coredump. Now everything is consistent ;)
- add rootlibdir option and use it on the libraries that require it
v9:
- indentation
v10:
- fix check for qrencode and libaudit
v11:
- unify handling of executable paths, provide options for all progs
This makes the meson build behave slightly differently than the
autoconf-based one, because we always first try to find the executable in the
filesystem, and fall back to the default. I think different handling of
loadkeys, setfont, and telinit was just a historical accident.
In addition to checking in $PATH, also check /usr/sbin/, /sbin for programs.
In Fedora $PATH includes /usr/sbin, (and /sbin is is a symlink to /usr/sbin),
but in Debian, those directories are not included in the path.
C.f. https://github.com/mesonbuild/meson/issues/1576.
- call all the options 'xxx-path' for clarity.
- sort man/rules/meson.build properly so it's stable
Add the 'convertible' type to the set of allowed chassis. This applies
to all devices that can be transformed by the user from laptop style to
tablet style.
This does not add any auto-detection, yet. It only makes 'set-chassis'
accept 'convertible' as valid input.
'systemctl --failed' is an extremely common operation and it's nice to have
a shortcut for it.
Revert "man: don't document systemctl --failed" and add the option back to
systemctl's help and shell completion scripts.
This reverts commit 036359ba8d.
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`
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.
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.
awk is an external program, and it is better to stick to shell built-ins.
Also, even with external awk, sort -u is redundant, because the shell does
this on its own.
