We can just use access() to check whether /run/system/system/ is a
directory, no need to involve stat(). The trick is to suffix the path
name with a dash.
This sounds like the better place to expose this than in "systemd-notify
--booted".
Also document the so far undocumented "unknown" state the command might
return. And rearrange the table of states documented to be more like the
one for "is-running".
Also, don't document the precise exit code of this function, just say
errors are reported != 0 or > 0...
This also allows us to drop build.h from a ton of files, hence do so.
Since we touched the #includes of those files, let's order them properly
according to CODING_STYLE.
Add (void) casting for a couple of functions where we knowingly ignore
the returning error code.
Use EXIT_FAILURE where appropriate.
Try to initialize structures at declaration time, or at once.
Also, make it slightly more powerful, by accepting a flags argument, and
make it safe for handling if more than one cmsg attribute happens to be
attached.
Currently, we guarantee that if two event-sources with the same priority
fire at the same time, they're always dispatched in the same order. While
this might sound nice in theory, there's is little benefit in providing
stability on that level. We have no control over the order the events are
reported, hence, we cannot guarantee that we get notified about both at
the same time.
By dropping the stability guarantee, we loose roughly 10% Heap swaps in
the prioq on a desktop cold-boot. Krzysztof Kotlenga even reported up to
20% on his tests. This sounds worth optimizing, so drop the stability
guarantee.
Add comment to prioq.c explaining what it does. And more importantly,
mention that we implement a Heap. It's more than annoying having to
figure out what the code actually does, without ever mentioning the word
'heap'.
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.
In some situations rebooting after fixing rootfs fails because
the job for reboot.target gets canceled. To avoid this
the "mode" parameter of the StartUnitReplace() call needs to be
set to "replace-irreversibly".
This introduces two new helpers alongside sd_bus_path_{encode,decode}(),
which work similarly to their counterparts, but accept a format-string as
input. This allows encoding and decoding multiple labels of a format
string at the same time.
Tested with a dummy service running 'sleep', modifying its CPUAffinity,
restarting the service and checking the ^Cpus_allowed entries in the
/proc/PID/status file.
Use the new code in config_parse_cpu_affinity2.
Tested by modifying CPUAffinity=... setting in /etc/systemd/system.conf
and reloading the daemon, then checking ^Cpus_allowed in /proc/1/status
to confirm the correct CPU mask is in place.
