This adds a new pair of API calls sd_bus_set_close_on_exit() and
sd_bus_get_close_on_exit(). They control whether an sd_bus object
attached to a an sd-event loop shall automatically be flushed/closed
when the event loop goes down. Usually that's a good thing, except for
very few cases where the bus connection is longer living than the event
loop it is attached on. Specifically, this is the case for nspawn, where
we run the event loop only while the container is up, but afterwards
still want to be able to use the bus connection.
This reorganizes the systemd.timer man page so that it doesn't claim
there are no implicit dependencies right after specifying the implicit
dependencies, and so that it matches the other man pages for units. This
fixes a mistake introduced by commit aed5cb03db.
A simple copy+paste mistake, since the reference to
systemd-localed.service was added to both locale.conf(5) and
vconsole.conf(5) in the same commit (8968e36f21).
This changes the ProtectSystem= documentation to refer in more explicit
words to the restrictions of ReadOnlyPath=, as sugegsted in #9857.
THis also extends the paragraph in ReadOnlyPath= that explains the hole.
Fixes: #9857
In the documentation for ConditionXYZ= we claimed that AssertXYZ= would
have an effect on unit state (which is wrong), while at the
documentation for AssertXYZ= we said it only has an effect on the job,
but not the unit (which is right). Let's fix this contradiction, and
only claim the latter.
Also, fix a couple of other things (for example, stop talking about a
"failure state", but let's just expressly called it "the 'failed' state",
as that's the actual name of that state.
Finally, let's emphasize again when the conditions/assertions are
executed, and that they hence are not useful to conditionalize deps.
Fixes: #10433
In the default journalctl output, unprintable entries are abbreviated as
“[<amount> blob data]”; using the same term in the documentation helps
users to quickly discover the option they need to add in order to see
those entries.
The &MEMORY_ACCOUNTING_DEFAULT; resolves to "yes" or "no" while the rest
of the paragraph talked about "on" and "off". Let's adjust this and
stick to "yes" and "no"...
Quite frankly I think it's not a particularly good idea to change the
docs based configuration changes... THis can only be incomplete, and the
wording is still very awkward since we repeat the same sentence twice.
This is useful for a couple of cases, I'm mostly interested in case #1:
1. Verifying "reasonable" values in a trivially scriptable way
2. Debugging unexpected time span parsing directly
Test Plan:
```
% build/systemd-analyze timespan 20
Original: 20
μs: 20
Human: 20us
% build/systemd-analyze timespan 20ms
Original: 20ms
μs: 20000
Human: 20ms
% build/systemd-analyze timespan 20z
Failed to parse time span '20z': Invalid argument
```
Add LogRateLimitIntervalSec= and LogRateLimitBurst= options for
services. If provided, these values get passed to the journald
client context, and those values are used in the rate limiting
function in the journal over the the journald.conf values.
Part of #10230
C.f. 287419c119ef961db487a281162ab037eba70c61: 'systemctl exit 42' can be
used to set an exit value and pulls in exit.target, which pulls in systemd-exit.service,
which calls org.fdo.Manager.Exit, which calls method_exit(), which sets the objective
to MANAGER_EXIT. Allow the same to happen through SuccessAction=exit.
v2: update for 'exit' and 'exit-force'
We would accept e.g. FailureAction=reboot-force in user units and then do an
exit in the user manager. Let's be stricter, and define "exit"/"exit-force" as
the only supported actions in user units.
v2:
- rename 'exit' to 'exit-force' and add new 'exit'
- add test for the parsing function
FailureAction=/SuccessAction= were added later then StartLimitAction=, so it
was easiest to refer to the existing description. But those two settings are
somewhat simpler (they just execute the action unconditionally) while
StartLimitAction= has additional timing and burst parameters, and they are
about to take on a more prominent role, so let's move the description of
allowed values.
