Now the service no longer starts immediately,
check if the config we generated makes sense as soon as possible.
The check isn't perfect because logrotate --debug wants to check
users required, there are two problems:
- /etc/passwd and /etc/group are sandboxed and we don't have
visibility of system users
- the check phase runs as nixbld which cannot su to other users
and logrotate fails on this
Until these two problems can be addressed, users-related checks
are filtered out, it's still much better than no check.
The check can be disabled with services.logrotate.checkConfig
if required
(bird also has a preCheck param, to prepare the environment
before check, but we can add it if it becomes necessary)
Since this makes for very verbose builds, we only show errors:
There is no way to control log level, but logrotate hardcodes
'error:' at common log level, so we can use grep, taking care
to keep error codes
Some manual tests:
───────┬──────────────────────────────────────────
│ File: valid-config.conf
───────┼──────────────────────────────────────────
1 │ missingok
───────┴──────────────────────────────────────────
logrotate --debug ok
grep ok
───────┬──────────────────────────────────────────
│ File: postrotate-no-end.conf
───────┼──────────────────────────────────────────
1 │ missingok
2 │ /file {
3 │ postrotate
4 │ test
5 │ }
───────┴──────────────────────────────────────────
error: postrotate-no-end.conf:prerotate, postrotate or preremove without endscript
───────┬──────────────────────────────────────────
│ File: missing-file.conf
───────┼──────────────────────────────────────────
1 │ "test" { daily }
───────┴──────────────────────────────────────────
error: stat of test failed: No such file or directory
───────┬──────────────────────────────────────────
│ File: unknown-option.conf
───────┼──────────────────────────────────────────
1 │ some syntax error
───────┴──────────────────────────────────────────
logrotate --debug ok
error: unknown-option.conf:1 unknown option 'some' -- ignoring line
───────┬──────────────────────────────────────────
│ File: unknown-user.conf
───────┼──────────────────────────────────────────
1 │ su notauser notagroup
───────┴──────────────────────────────────────────
error: unknown-user.conf:1 unknown user 'notauser'
In particular note that logrotate would not error on unknown option
(it just ignores the line) but this change makes the check fail.
