[Bug]: I can't see my files in the root of my accounts after NC upgrade (27) #40322

Bug description

Quickly: After the upgrade from NC25 to 26, (I later upgraded to NC27 to see if the bug was still there, it still is) I can't see my files in the root of my accounts, I only see the content of a folder another local user shared to me.

Details: my user is benjamin, and local user jean-pierre shared (long ago) 2 folders with me: "numerisation" and "videos" Since NC26 upgrade, I am now seeing "numerisation" folder content at the root of my account instead of my own files. I asked jean-pierre to stop sharing this with me, and now I see "video" folders content from jean-pierre at the root of my account instead of my own files...

I found that in oc_mounts table I had the following entry :

| 113 | 23 | 659747 | benjamin | /benjamin/files/ | NULL | OCA\Files_Sharing\MountProvider |

659747 being the fileid of the "numerisation" folder in jean-pierre files.

after jean-pierre stopped sharing, I now have this entry in oc_mounts :

| 126 | 23 | 569282 | benjamin | /benjamin/files/ | NULL | OCA\Files_Sharing\MountProvider |

569282 being the fileid of jean-pierre "videos" folder ...

of course, in oc_mounts, I also have this entry,

| 1 | 1 | 1 | benjamin | /benjamin/ | NULL | OC\Files\Mount\LocalHomeMountProvider |

(which is normal)

I looked at a MySQL backup from before the upgrade to NC25/26/27, and I found that the entry 113 in oc_mounts had "/benjamin/files/numerisations/" as mount_point, not "/benjamin/files/"

If I change (manually in the DB) it back to the old value, and reload a NC page, it is changed back to "/benjamin/files/"

Steps to reproduce

I am not able to reproduce it on a new NC, sorry

Expected behavior

I expect to find my own files at the root of my account, not the content of a shared folder.

Additional info

This is a very old (it was an owncloud 8 and upgraded since to NC 10 to 27 as time goes by) installation. I suspect this could be linked to #37473

Follow-up of my research on this bug:

I traced a simple call to "php8.0 occ info:file /benjamin/files/" (on the original NC27 + file_sharing 1.19.0) and it does the following SQL queries: 

                691511 Query    START TRANSACTION

Same symptoms here with a 25.0.10 install happening without major updates. User reports missing "all files" except his shares in "shareoverview" and deleted files in "trashbin" over night. Disabling File Sharing app brings back all files in root. With File Sharing app enabled and trying to list all files in root or via browser refresh of the page there is the following log entry - hope that helps debugging:

I found a solution (partially)

commented out line 109-112 of apps/files_sharing/lib/SharedMount.php disabling the cache in verifyMountPoint()

when I do that, the oc_mount is filled properly and the nextcloud files are now all properly visible

ALSO, if I disable my MEMCACHED configuration in config/config.php, it works TOO...

replaced memcached by redis, uncommented the cache in SharedMount.php, and everything is working fine and quick

don't know what was wrong with my config.php, but maybe this deserve a line or two in the documentation if I did something wrong? ;)

In theory Memcached should have been fine with the way you configured it AFAIK (assuming this is a standalone server). Personally I get the sense Memcached isn't used very often in new NC installations these days however.

What versions, specifically, of these do you have in this installation?

memcached launched with -m 64 -s /tmp/ben.memcached.sock -u ben on a debian 10.13 (buster, I know, quite an oldstable :) ) but with php-sury packages for php.

We are not using memcached and disabling the cache in verifyMountPoint() does not help either. Unfortunately we experience the same symptoms but for a different reason as your workaround does not apply to our setup. Disabling file sharing is not an option. I will open a new issue for that. Sorry for the noise.

So interestingly came across another party where memcached was the culprit on the Forum today:

Noting here simply for future reference for now.
