Bogus value in quota-available-bytes #23058

Closed DagNygren closed 2 months ago

DagNygren commented 4 years ago

How to use GitHub

Steps to reproduce

1.Do a PROPFIND on a DAV resource, What I did was: curl -k -i -X PROPFIND --basic --user dag https://owncloud.newtech.fi/remote.php/dav/files/dag/ >/home/dag/owncloud_response.txt

  1. Take a look at the result. Easier if using xmllint. You vill have to remove the header first.
  2. Check the result listing of the files and pay attention to the quota-available-bytes entry

Expected behaviour

The field should contain a reasonable value

Actual behaviour

You will see negative values

szaimen commented 3 years ago

Is this Issue still valid in NC21.0.2? If not, please close this issue. Thanks! :)

DagNygren commented 3 years ago

Nope. The problem is still there

But a litte more information: It seems like this bogus value is only wrong for directories that are remotely mounted on Eternal storage by SFTP

jmue commented 2 years ago

I get the bogus quota-available-bytes value too if I set the user quota to 'Default' or 'Unlimited'. If I set a concrete value the quota-available-bytes property is filled correctly. I use no external storage backends nor e2e.

voxHumana0 commented 2 years ago

I experience this issue with version 23.0.0.0 and 23.0.3.2 or whatever the newest version is as of now. I removed the other ~ 100 d:response fields, each having the same bogus -3 value. See below... The quota here is set to "unlimited" as well.

I use ExpanDrive as sync client.

BTW, this -3 value comes from FileInfo.php when a file size check is performed.

I just can't find the spot in RFC4331 where this -3 value appears. Apparently, some DAV clients crash upon encountering this value.

Oh nevermind, changing the value to some other magic value "424242424242" didn't work. I'll contact the ExtenDrive support then.

Hi, please update to 24.0.9 or better 25.0.3 and report back if it fixes the issue. Thank you!

My goal is to add a label like e.g. 25-feedback to this ticket of an up-to-date major Nextcloud version where the bug could be reproduced. However this is not going to work without your help. So thanks for all your effort!

If you don't manage to reproduce the issue in time and the issue gets closed but you can reproduce the issue afterwards, feel free to create a new bug report with up-to-date information by following this link: https://github.com/nextcloud/server/issues/new?assignees=&labels=bug%2C0.+Needs+triage&template=BUG_REPORT.yml&title=%5BBug%5D%3A+

jmue commented 1 year ago

I'm on 25.0.3 and the issue still persists.

joshtrichards commented 2 months ago

This is not a bug. It's a valid return value we rely on:
