save_needle Minion tasks fail frequently and needles could get lost
0%
Description
Observation¶
The save_needle
Minion task fails frequently on OSD and also sometimes on o3.
This can be observed using the following query parameters: https://openqa.suse.de/minion/jobs?state=failed&offset=0&task=save_needle
I'm going to remove most of these jobs to calm down the alert but right now 24 jobs have piled up over 2 month. However, the problem actually exists longer than 2 month but the failures have been manually cleaned up so far.
The problem here is always that the Git working tree is in a state which can not be handled by the task:
1.
"result" => {
"error" => "<strong>Failed to save addon_products-module-dev-tools-pvm-20200805.</strong><br><pre>Unable to commit via Git: On branch master\nYour branch is up to date with 'origin/master'.\n\nnothing to commit, working tree clean</pre>"
},
2.
"result" => {
"error" => "<strong>Failed to save manually_add_profile-AppArmor-Chose-a-program-to-generate-a-profile-20200827.</strong><br><pre>Unable to reset repository to origin/master: error: cannot rebase: Your index contains uncommitted changes.\nerror: Please commit or stash them.</pre>"
},
Acceptance criteria¶
- AC1: The
save_needle
task can handle problematic situations mentioned below.
Suggestions¶
It would be useful if the task would be able to handle the problematic situations itself instead of requiring manual intervention. Note that the delete_needle
task (which shares the same Git code) is also affected. We have likely less problems there because that task is not executed that often.
Problematic situations¶
- No diff has been produced which could be committed: Maybe that's simply when there's no actual change and we can simply return early in that case.
- The Git directory contains uncommitted changes: We could save these changes on a new branch before rebasing.
- We can not push the new commit because in the meantime new commits have been pushed to the remote from elsewhere: Just repeat the procedure.
- The fetch needles script is interfering.

I think you once already proposed a solution to "repair" the git state. Can you reference that again so that we can think about what we can take from that?

Another git process seems to be running in this repository, e.g.
an editor opened by 'git commit'. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.</pre>

The last error you've mentioned is fixed by https://github.com/os-autoinst/openQA/pull/4835.

Apparently it's coming back despite our best efforts to ignore it ;-) Of course the impact is limited, and it's not preventing people from being able to save needles.

I suspect that "Failed to save … nothing to commit, working tree clean" means that there is another parallel save_needles job that already handled that. Or the fetchneedles run every minute is "handling" such case, maybe by pruning uncommited files from git repos.
