Closes#40883. As described in the issue, it's not "jobs" that are
marked, and also the name is unnecessarilly long.
I think we don't need any compatibility measures here. At least in the
rpm world, package upgrade scripts go through the helper which is part
of the package so the new systemctl and the new helper are upgraded
together.
This reverts commit 351b4dd123.
I'm pretty sure we should not create more of these multiplexer
interfaces, which in this specific also leads to a fair bit of
confusion: start/stop/reload-or-restart --marked all enqueue
all job types.
Instead, a dedicated verb will be introduced in later commits.
I expressed the issue I have with parse_tristate_argument()
in #37751: it doesn't add any value to direct use of parse_tristate();
on the contrary, it doesn't support means to reset the arg to "auto"/-1 state.
The mere reason it existed is that we need a int type ret param.
Since the previous attempt to address this mess failed, let's
try to make the function more useful by making it accept "auto".
I figure this is useful on its own.
As requested in
https://github.com/systemd/systemd/pull/40652#discussion_r2831833996,
the function name is suffixed with _with_auto() to establish
that "auto" is handled internally.
The immediate impulse for this change is the fedora scriptlet which called:
/usr/lib/systemd/systemd-update-helper install-system-units cryptsetup-pre.target cryptsetup.target getty@.service ... system-systemd\x2dcryptsetup.slice system-systemd\x2dveritysetup.slice ...
which called
systemctl preset cryptsetup-pre.target cryptsetup.target getty@.service ... system-systemd\x2dcryptsetup.slice system-systemd\x2dveritysetup.slice ...
which threw an error that system-systemdx2dcryptsetup.slice does not exist
and did nothing at all. (The backslash is consumed by the shell.)
The obvious fix here is to figure out more levels of escaping… But we should
do something more robust in such cases.
If we fail in processing of a single unit, let preset all continue processing
units, report the failure through 'changes'. At the end, return failure. In
general, for operations which operate on a list of units specified by the user,
fail the whole operation if any of the individual operations failed. The only
operation where we don't do this is 'preset-all'.
$ SYSTEMD_LOG_LEVEL=debug build/systemctl --root=/ preset asdf1.servie asdf2.path; echo $?
Cannot find unit asdf1.servie.service.
Cannot find unit asdf2.path.
Failed to preset unit: Unit asdf1.servie.service does not exist
Failed to preset unit: Unit asdf2.path does not exist

While at it, fix double logging in the manager: dump_unit_changes() already
logs about errors, so the manager should only log on success.
As announced by a few releases now, finally drop support for
sysvinit scripts.
Keep rc-local generator for now, as it's really a distinct
feature even though from the same era.
In all cases, everything that we list in 'extract', we also list in
'sources'. We can simplify things by automatically appending the first
list to the second.
In the listings, move 'extract' key right below 'sources', since now
they are both "sources", just with slightly different meanings.
Make bus acquisition conditional in verb_edit() and verb_cat(), following
the same pattern used in verb_enable(). When install_client_side() returns
non-zero (indicating --global, --root, offline, or similar scenarios), skip
acquiring a D-Bus connection and perform all operations client-side.
Changes:
- Only acquire bus when install_client_side() returns NO
- Use mangle_names() instead of expand_unit_names() in client-side mode
- Pass force_client_side flag based on bus availability
- Skip bus-dependent operations (need_daemon_reload, etc.) when bus is NULL
This allows 'systemctl edit --global' and 'systemctl cat --global' to work
correctly, fixing the regression introduced by commit d77d42ed3a.
Test cases added to verify:
- Creating and editing global user units with --runtime
- Reading global units with cat --global
- Proper detection and rejection of masked units in client-side mode
- Tests use /run/ instead of /etc/ for safer temporary testing
Fixes https://github.com/systemd/systemd/issues/31272
When operating in client-side mode (force_client_side=true), unit_find_paths()
now checks if the unit file is masked (symlinked to /dev/null or empty) and
returns -ERFKILL, matching the behavior of the server-side path.
This centralizes masked unit detection in one place, making it consistent
across both client-side and server-side operations.
`systemctl show`'s `--timestamp` flag is supposed to reformat all
timestamp-based properties. However, the logic for detecting these
properties was incomplete and only checked if the name ended in
Timestamp.
Expand the check to explicitly include some non-"timestamp" named
properties that really are timestamps.
Fixes: https://github.com/systemd/systemd/issues/39282
When parsing an absolute time specification like `hh:mm` for the
`shutdown` command, the code interprets a time in the past as "tomorrow
at this time". It currently implements this by adding a fixed 24-hour
duration (`USEC_PER_DAY`) to the timestamp.
This assumption breaks across DST transitions, as the day might not be
24 hours long. This can cause the shutdown to be scheduled at the wrong
time (typically off by one hour in either direction).
Change the logic to perform calendar arithmetic instead of timestamp
arithmetic. If the calculated time is in the past, we increment
`tm.tm_mday` and call `mktime_or_timegm_usec()` a second time.
This delegates all date normalization logic to `mktime()`, which
correctly handles all edge cases, including DST transitions, month-end
rollovers, and leap years.

When Type=notify-reload got introduced, it wasn't intended to be
mutually exclusive with ExecReload=. However, currently ExecReload=
is immediately forked off after the service main process is signaled,
leaving states in between essentially undefined. Given so broken
it is I doubt any sane user is using this setup, hence I took a stab
to rework everything:
1. Extensions are refreshed (unchanged)
2. ExecReload= is forked off without signaling the process
3a. If RELOADING=1 is sent during the ExecReload= invocation,
we'd refrain from signaling the process again, instead
just transition to SERVICE_RELOAD_NOTIFY directly and
wait for READY=1
3b. If not, signal the process after ExecReload= finishes
(from now on the same as Type=notify-reload w/o ExecReload=)
4. To accomodate the use case of performing post-reload tasks,
ExecReloadPost= is introduced which executes after READY=1
The new model greatly simplifies things, as no control processes
will be around in SERVICE_RELOAD_SIGNAL and SERVICE_RELOAD_NOTIFY
states.

When calling systemctl enable/disable/reenable --now, we'd always fail with
error when operating offline. This seemly overly restricitive. In particular,
if systemd is not running at all, the service is not running either, so
complaining that we can't stop it is completely unnecessary. But even when
operating in a chroot where systemd is not running, let's just emit a warning
and return success. It's fairly common to have installation or package scripts
which do such calls and not starting/restarting the service in those scenarios
is the desired and expected operation. (If --now is called in combination
with --global or --root=, keep returning an error.)
Also make the messages nicer. I was adding some docs to tell the user to run
'systemctl enable --now', and checked how the command can fail, and the error
message that the user might see in some common scenarios was too complicated.
Split it up to be nicer.
Let's not leak details from src/shared and src/libsystemd into
src/basic, even though you can't actually do anything useful with
just forward declarations from src/shared.
The sd-forward.h header is put in src/libsystemd/sd-common as we
don't have a directory for shared internal headers for libsystemd
yet.
Let's also rename forward.h to basic-forward.h to keep things
self-explanatory.
Traditionally, halt is called at the end of the init script on
reboot/shutdown. To support such usecase, previously we read the current
runlevel from utmp and set force flag on reboot/shutdown.
This drops the support for such the usecase.
Note, neither supported nor tested, but hopefully still the command can
be used in the end of the sysv init script by specifying -ff.
- parse_shutdown_time_spec() is used only by systemctl-compat-shutdown.c,
- talk_initctl() and action_to_runlevel() are used only by systemctl-compat-telinit.c,
- the exit code enum is widely used in systemctl, hence moved to systemctl-util.h.
No functional change, preparation for later changes.

This is a tiny amount of code and does not warrant having a separate file
and spawning a separate instance of the compiler during the build.
Note: it took me a while to confirm that the contents of that table and
function don't end up in libsystemd.so. The issue is that they _are_ present in
it, unless LTO is used. We actually use link_whole[libbasic_static] for
libsystemd, so we end up with all that code there. LTO is needed to clean
that up.
