[skjnldsv]

Fix #24891

Is this a god time to delete the share if the node doesn't exists?

Not sure it's the right spot to catch it. The manager (or somewhere up the stack) might make more sense to call it? Same with unsharing (provided it is free of side effects – e.g. temporarily unavailable storage, but that SHOULD fail differently).

I'm wondering a bit if in that scenario the cache is actually an instance of a FailedCache so we can just skip the search call in such a case in the view directly before the search is called when iterating over the mounts

server/lib/private/Files/View.php

Lines 1663 to 1669 in f98fed3

	$mountPoint = $mount->getMountPoint();
	$storage = $mount->getStorage();
	if ($storage) {
	$cache = $storage->getCache('');
	$relativeMountPoint = substr($mountPoint, $rootLength);
	$results = call_user_func_array([$cache, $method], $args);

That would be a bit cleaner in my opinion, but hard to tell from the trace if that would work.

Fell free to find a better way. This is way out of my current php focus, this was a quickfix for proper catching. :)

please resolve the conflict, looks like a quick win

[solracsf]

Any chance to see this on v25 and backported?

Fixed already by e198dc1

@skjnldsv this happens in latest v22, isn't that commit included?
