Issue indexer queue not getting processed, 8000+ unfinished jobs

[yusf]

This instance is a couple of years old, so it's been through some updates, and one server migration.

I tried deleting /app/data/appdata/indexers in order to try and rebuild the indexing but since found that workers do not process that queue anyway. The issue indexer work queue is building up without getting worked on. Adding workers manually doesn’t help.

I found a note for a recommendation from the 1.15 release, stating:

It is recommended to ensure that queues are empty before upgrading using gitea manager flush-queues or on the admin pages.

Should I do that?

[yusf]

I went ahead and tried to flush the queue:

sudo -u git /home/git/gitea/gitea -c /run/gitea/app.ini  manager flush-queues --timeout 20m

but even with that generous timeout value it timed out:

flush timeout with non-empty queues: issue_indexer

I've little to no idea of what I'm doing here btw.

[yusf]

The queue has still not being processed, but 13000 flush workes (and probably counting) have seemingly been added.

I’d really appreciate some help before this instance blows up

I'm using Gitea for quite some years as well and this got me curious. The current queue can be seen in the webinterface of Gitea at https://your-domain/admin/monitor. My queues however are at 0.

If you have not done yet I would check the logs of gitea if there are any abnormalities in regards to queue handling. Error messages at startup?

The same website also allows to see stacktraces for the running processes.

In the end it may be a bug within Gitea that would need reporting and fixing upstream.

@yusf For me that command says "Flushed" instantly. Maybe something is stuck in the queue. Looks like you can pass a "--debug" flag to the command. Can you see what it's doing?

[yusf]

@girish said in Issue indexer queue not getting processed, 8000+ unfinished jobs:

--debug

With what command? At least not gitea manager flush-queues.

[yusf]

@fbartels I have skimmed the logs but I haven't seen any abnormalities (though logs are quite verbose). I don't know what a stacktrace is.

yes, --debug is an option for that command.

[yusf]

@girish Must've got it wrong somehow. Anyway, --debug only adds one line of little insight:

sudo -u git /home/git/gitea/gitea -c /run/gitea/app.ini manager flush-queues --debug

flush timeout with non-empty queues: issue_indexer

@yusf I guess we have to ask upstream for ideas...

But I found https://github.com/go-gitea/gitea/issues/17563 . It suggests changing the indexer to db instead of the default bleve. Don't know if that will help your case.

I think another idea is to figure where these jobs are stored and clear that. There is a task table, probably there?

@girish Setting

[indexer]
ISSUE_INDEXER_TYPE=db

in app.ini solved the issue immediately. Thanks alot!

Now I'm curious to know what db means in this context (but the urgency is gone ). Should the Cloudron package have db as ISSUE_INDEXER_TYPE out of the box, for example?

Some Cloudron app config data got alot of legacy files from earlier versions, so sometimes it's hard to know what the true good defaults are.
