[Bug]: Nextcloud not resolving directory with name "0" and instead trying to reference subdirectory directly.

[surfrock66]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).

• I agree to follow Nextcloud's Code of Conduct.

Bug description

I have a fileserver share mounted to my nextcloud server as an external storage at "/mnt/fileserver" mapped as an external storage to "/mnt/fileserver/surfrock66/Videos/TV". Inside here is a directory for each alphabet letter, and "0" (zero) for shows with numbers I have ripped from Blu-Ray. This works generally well, except for the folder "0". I am getting spammed multiple times a minute with the following log entry:

This folder does not exist like this; it is nested inside the "0" folder, but nextcloud appears to be skipping the 0 folder:

root@sr66-nxt-01:~# ls /mnt/fileserver/surfrock66/Videos/TV/0/
total 4.0K
4.0K drwxrwxr-x 6 surfrock66 family 4.0K Dec 23 20:09 24

The other subfolders which are named with alphabet letters are fine and do not exhibit this behavior, it appears to be something specific to the "0" folder.

Steps to reproduce

1. Mount an NFS share at "/mnt/fileserver"
2. Add an external storage of type "Local" to "/mnt/fileserver/somesubfolder"
3. Create a directory in that folder titled "0"
4. Create additional directories in the "0" directory
5. Monitor nextcloud.log where cron will spam errors resolving the subdirectories directly off the path multiple times a second.

Expected behavior

The folder is mounted and shows up correctly

Upgraded to a MAJOR version (ex. 28 to 29)

Just to clarify: this worked fine on v29 but broke when you upgraded this environment to v30? Or when you upgraded to v30.0.4 from ???

Do you see the same behavior if you mount a non-NFS Local mount (e.g. /tmp/foobar) and create a 0 folder within it?

[surfrock66]

I guess I am not actually sure because I created the folder right after upgrading. The timing was pretty close to each other.

🤦 Reproduced. Ouch!

This code has been in place for many years. I can't believe it's not been noted until now. I want to do some digging before pushing formally. Also want to review the current test coverage. That'll have to wait until tomorrow at the earliest.

If you want to test the fix in your environment, change line 498 of lib/private/Files/Cache/Scanner.php from:

server/lib/private/Files/Cache/Scanner.php

Line 498 in f82ff16

$child = $path ? $path . '/' . $file : $file;

to:

			$child = isset($path) ? $path . '/' . $file : $file;

[surfrock66]

Applied the fix, rebooted, and the message appears to be gone, however when I browse to the "0" folder I still see no subfolders. This may just take some time, I'll check again in the morning.

Overnight the contents of the directory showed up, I think that fix works.
