(Core :: Gecko Profiler, defect)

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

I wanted to catch profile in latest Mozilla Firefox Nightly 80.0a1, because of constant hangs on opening new website pages for last few days, but I can't do that, as Firefox Profiles shows me this error:

Firefox Profiler

Couldn't retrieve the profile from the Firefox.

NotFoundError: IDBDatabase.transaction: 'symbol-tables' is not a known object store name

The full stack has been written to the Web Console.

In Web Console I have this errors:

This looks more like a front-end issue.

Julien, what do you think? (If I'm correct, please open a corresponding issue on Github.)

Yeah this is clearly a frontend problems.
We already got a mention of a similar problem, and the problem is clear: the DB we use is present, but doesn't have our object store. We don't know how this can happen. Maybe some eviction that didn't happen properly (eviction is supposed to remove all data for an origin), in this case I'm thinking of a bug in Firefox.

To fix it quickly you can:

1. go to profiler.firefox.com
2. go to the devtools' storage panel
3. delete the indexeddb that exists for the origin.

Before 3 I'd be interested to see what's there, can you please make me a screenshot please? Thanks!

Resetting the severity so that the triage owner can decide. This doesn't seem like an S1 severity to me, though.

Thanks for the screenshots!
Yeah, as I suspected, we have a DB with version 2 with no objectstores, which shouldn't ever happen.

I'm tempted to bump the version to force creating the db again. Maybe we had a bad version in the past? Or some version of Firefox had a bug with eviction?

I'll be closing this bug here for now, but filed https://github.com/firefox-devtools/profiler/issues/2637 on our frontend repository.
Thanks!

Please do. It will help other people with same issue as mine.

OK. Thank you very much for creating it in my stead.
