The information about the unit for which files are being parsed
is passed all the way down. This way messages land in the journal
with proper UNIT=... or USER_UNIT=... attribution.
'systemctl status' and 'journalctl -u' not displaying those messages
has been a source of confusion for users, since the journal entry for
a misspelt setting was often logged quite a bit earlier than the
failure to start a unit.

This bit of code is mostly stolen from coredump.c. We construct
a simple journal message and append the bootchart file in the
journal automatically.
You can extract the latest bootchart from the current boot with
something like:
$ journalctl -b MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518 --field=BOOTCHART
which prints it to stdout.
None of the other logic is touched. The journal entry is created
even if bootchart was run manually, which is probably wrong.
If the configured number of samples was close to MAXSAMPLES,
the samples buffer could be overrun:
- by 1, because of off-by-one in the condition (samples > arg_samples_len),
and
- by many in case of an overrun, because the number of samples to
capture was increased, instead of being decreased.
Simplify things by converting to a normal for-loop.
In store.c: change buffer size from 4095 to 4096. 4095 is a strange
number.
Let's update bootchar to share the coding style a bit more with the rest
of the package.
- Some tabs/spaces fixes
- add #pragma to header
- split up header so that we have a 1:1 relation between .c and .h files
like everywhere else
- Prefix user command line arguments/configuration settings with "arg_".
- other coding style fixes
This reverts commit 0ea9530d40.
attribute(cleanup) can only be used inside functions (*of, sysfd
are leaked).
Cleanup functions are only called once when exiting scope (*f
is leaked twice).
Turning off filtering with --filter is just too confusing.
Config option "Filter" doesn't have to be changed, here
"Filter=yes" already meant to filter.
When we merged systemd-bootchart we omitted relicensing this
to LGPL. Now that code is being used for other purposes we
need to make sure the code is shareable within systemd
without further problems.
The original committers and contributors of bootchart before it
was merged all have agreed with the relicensing.
Bootchart is renamed to 'systemd-bootchart' and installed as
/usr/lib/systemd/systemd-bootchart. The configuration file
will reside in /etc/systemd/bootchart.conf.
