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

[MichaIng]

Steps to reproduce

1. Update from 17.0.1.1 to 18.0.0 Beta1 via web-based updater
2. 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?

Accessing logs:

On Tasks and users page as well...

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?

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...
