Those functions take a pointer to a timestamp and return a timestamp pointer,
so the reader would be justified to think that those are just getters. Rename
them to avoid confusion.
This adds a new structure UnitDefaults which embedds the various default
settings for units we maintain. We so far maintained two sets of
variables for this, one in main.c as static variables and one in the
Manager structure. This moves them into a common structure.
This is most just search/replace, i.e. very dumb refactoring.
The fact that we now use a common structure for this allows us further
refactorings later.
Inspired by the discussions on #27890
This is supposed to be a help for compilers to apply optimizations on
functions where they can't determine whether they are const/pure on
their own. For static, local functions the compiler can do this on its
own easily however, hence the decoration with pure/const is just noise.
Let's drop it, and let the compiler to its thing better.
(Use it for exported functions, since compilers can't 'reach-over' into
other modules to determine if they are pure, except if LTO is used)
As it says on the tin, configures the unit to survive a soft reboot.
Currently all the following options have to be set by hand:
Conflicts=reboot.target kexec.target poweroff.target halt.target
Before=reboot.target kexec.target poweroff.target halt.target
After=sysinit.target basic.target
DefaultDependencies=no
IgnoreOnIsolate=yes
This is not very user friendly. If new default dependencies are added,
or new shutdown/reboot types, they also have to be added manually.
The new option is much simpler, easy to find, and does the right thing
by default.
If we're doing a daemon-reload, we'll be going from TIMER_DEAD => TIMER_WAITING,
so we won't use inactive_exit_timestamp because TIMER_DEAD != UNIT_ACTIVE, even
though inactive_exit_timestamp is serialized/deserialized and will be valid after
the daemon-reload.
This issue can lead to timers never firing as we'll always calculate the next
elapse based on the current realtime on daemon-reload, so if daemon-reload happens
often enough, the elapse interval will be moved into the future every time, which
means the timer will never trigger.
To fix the issue, let's always use inactive_exit_timestamp if it is set, and only
fall back to the current realtime if it is not set.
Now that we have a potentially pinned fdstore let's add a concept for
cleaning it explicitly on user requested. Let's expose this via
"systemctl clean", i.e. the same way as user directories are cleaned.
This fix unfortunately introduced a much worse regression that
is affecting many users, so let's revert it for now and rework
it in the next release.
This reverts commit 5ded3917a1.

(s) is just ugly with a vibe of DOS. In most cases just using the normal plural
form is more natural and gramatically correct.
There are some log_debug() statements left, and texts in foreign licenses or
headers. Those are not touched on purpose.
Same idea as 03677889f0.
No functional change intended. The type of the iterator is generally changed to
be 'const char*' instead of 'char*'. Despite the type commonly used, modifying
the string was not allowed.
I adjusted the naming of some short variables for clarity and reduced the scope
of some variable declarations in code that was being touched anyway.
