- Increase the global level for broadcaster's logging to 3 so that users can ignore event messages by lowering the logging level. It reduces information noise.
- Making sure the context is properly injected into the broadcaster, this will allow the -v flag value to be used also in that broadcaster, rather than the above global value.
- test: use cancellation from ktesting
- golangci-hints: checked error return value
* Fix a job quota related deadlock
In case ResourceQuota is used and sets a max # of jobs, a CronJob may get
trapped in a deadlock:
1. Job quota for a namespace is reached.
2. CronJob controller can't create a new job, because quota is
reached.
3. Cleanup of jobs owned by a cronjob doesn't happen, because a
control loop iteration is finished because of an error to create a
job.
To fix this we stop early quitting from a control loop iteration when
cronjob reconciliation failed and always let old jobs to be cleaned up.
* Dont reorder imports
* Don't stop requeuing on reconciliation error
Previous code only logged the reconciliation error inside jm.sync() and
didn't return the reconciliation error to it's invoker
processNextWorkItem().
Adding a copy-paste back to avoid this issue.
* Remove copy-pasted cleanupFinishedJobs()
Now we always call jm.cleanupFinishedJobs() first and then
jm.syncCronJob().
We also extract cronJobCopy and updateStatus outside jm.syncCronJob
function and pass pointers to them in both jm.syncCronJob and
jm.cleanupFinishedJobs to make delayed updates handling more explicit
and not dependent on the order in which cleanupFinishedJobs and
syncCronJob are invoked.
* Return updateStatus bool instead of changing the reference
* Explicitly ignore err in tests to fix linter
The two methods nextScheduledTimeDuration and getNextScheduleTime have a
lot of similarities, so this commit squashes the common parts together
along with getMostRecentScheduleTime to avoid code duplication.
CRON_TZ variable slipped in during upgrading github.com/robfig/cron
library. It allows setting a time zone which is a long requested
feature but one that is not officially supported. This adds warning
event since users should not rely on unsupported features.
