[18.0.0 Beta1] Deprecated event type for OCP\IPreview:PreviewRequested #18331

MichaIng · 2019-12-10T13:01:08Z

Steps to reproduce

Update from 17.0.1.1 to 18.0.0 Beta1 via web-based updater
Check logs

Expected behaviour

No log flood

Actual behaviour

Secondly the following info log is generated

[no app in context] Info: Deprecated event type for OCP\IPreview:PreviewRequested: Symfony\Component\EventDispatcher\GenericEvent

GET /nextcloud/core/preview?fileId=676196&c=064f1cdb27c480fc2ad58354a4250a5c&x=250&y=250&forceIcon=0
from 95.81.18.51 by Micha at 2019-12-10T13:55:48+01:00

Clearly related to preview generation jobs, probably in combination with the new Photos app replacing Gallery?

But I cannot see further issues that seem to be related.

Actually such logs show up when accessing several other apps/pages as well. Is this intended, e.g. during Beta phase?

MichaIng · 2019-12-10T13:23:09Z

Ah just found the PR which most likely resolves this? #18225
EDIT: Nope!

Probably it is best to omit those logs, so they do not flood the log file?

twinkybot · 2020-01-14T13:30:15Z

Hi there, I am affected by this Log.info flood as well

@twinkybot
Jep, everyone is affected, expectedly. Not a state which should be released IMO, especially since currently there are still Nextcloud-internal/core apps affected, but not my decision...

Feel free to open a pull request and suggest to use $this->logger->debug ;)

This is to reduce log flooding on info log level, which is currently expected tue to deprecated event use in many apps and core: #18331 This information is helpful for developers only, hence should be sufficient as debug log. Especially due to the extremely high frequency this log can happen, this currently practically forces admins to disable info logs, which conflicts with other needs.

PR merged, log level for those kind of messages reduced to debug. This is no solution but the issue is known and it is task of app devs to migrate used event types. I mark this hence as closed.

The same issue again on Nextcloud 20.0

Anyone with a solution to stop this flood of errors in log?

Please update to Beta 8, at least it helped in my case.

Well, I disabled previews and found that this is generic error for other things:

rybaha · 2021-02-03T12:39:55Z

Setting
'loglevel' => 2,
helped in my case.

MichaIng · 2021-02-03T13:17:50Z

Ah I totally forgot that I did the same on my system. I can verify the massive deprecation logs (debug and info level) of various types and across various apps.

Could you please open a new issue about those? If related to a specific app, at best at the individual apps repository. On a closed issue this will not get attention, when not being subscribed to it already (like me).
