[Bug]: setting 'quota_include_external_storage' => true breaks directory share links with Argument #2 ($user) must be of type OCP\\IUser, null given

⚠️ 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).
Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
I agree to follow Nextcloud's Code of Conduct.

Bug description

After upgrading to NC version 32, if 'quota_include_external_storage' => true was set, share links that share a directory located on an external storage can no longer be accessed.

The user-facing error message reads "This folder is unavailable, please try again later or contact the administration"), see the screenshot:

Debug log is attached below and reports:
OC_Helper::getGlobalStorageInfo(): Argument #2 ($user) must be of type OCP\\IUser, null given, called in /opt/www/nextcloud/lib/private/legacy/OC_Helper.php on line 278

Steps to reproduce

Set 'quota_include_external_storage' => true
Add external storage (here: local file)
Create a directory
Create share link to that directory
Open share link
Notice the error
Set 'quota_include_external_storage' => false
Refresh share link
Directory can be accessed

Expected behavior

Setting 'quota_include_external_storage' => true does not break directory share links

}

Additional info

getGlobalStorageInfo expects a logged-in user, even if there is none because it's a public share link. Adding a null check to $user appears to solve the issue.

I have the same problem, and setting 'quota_include_external_storage' => false solves indeed the problem but since this has been opened in october, why is still in triage?

@susnux

since this has been opened in october, why is still in triage

Not sure. Maybe because the OC_Helper stuff is deprecated (see e143921)?
Although not sure if the replacement library (?) would actually fix this.

@susnux maybe this will be addressed in version 33?

Hi, I believe this has been fixed somehow. At least I cannot reproduce it anymore with 32.0.8.

Can we reopen this?

I can still reproduce in the Nextcloud Hub 26 Winter (33.0.3).

code wise not fixed

fix(OC_Helper): properly calculate quota of shared storages
