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

Created on 10 Dec 2019  路  9Comments  路  Source: nextcloud/server

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...

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

PR is up: #18966

MichaIng picture MichaIng on 18 Jan 2020

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.
