Random PHP error after moving files around, what does it mean?

JasonBayton · November 19, 2016, 11:34pm

I’ve been seeing this message when moving stuff around recently, I can’t make sense of it. Anyone able to sanitise and relay back to me what the issue may be please?

"app":"PHP","message":"Uncaught Error: Access to undeclared static property: OC\\Files\\Filesystem::$normalizedPathCache in \/var\/www\/html\/lib\/private\/Files\/Filesystem.php:773\nStack trace:\n#0 \/var\/www\/html\/lib\/private\/Files\/View.php(2034): OC\\Files\\Filesystem::normalizePath('\/jason\/files\/So...')\n#1 \/var\/www\/html\/lib\/private\/Files\/View.php(1152): OC\\Files\\View->unlockFile('\/Software\/Nextc...', 1)\n#2 [internal function]: OC\\Files\\View->OC\\Files\\{closure}()\n#3 \/var\/www\/html\/apps\/files_external\/3rdparty\/icewind\/streams\/src\/CallbackWrapper.php(109): call_user_func(Object(Closure))\n#4 [internal function]: Icewind\\Streams\\CallbackWrapper->stream_close()\n#5 {main}\n  thrown at \/var\/www\/html\/lib\/private\/Files\/Filesystem.php#773","level":3,"time":"2016-11-19T23:16:07+00:00","method":"GET","url":"\/apps\/activity\/api\/v2\/activity\/filter?format=json&object_type=files&object_id=68941","user":"jason"}

And unrelated this seems like a DB error which may have happened when I bounced the remote mariaDB, but also maybe not.

app":"no app in context","message":"Exception: {\"Exception\":\"Doctrine\\\\DBAL\\\\Exception\\\\DriverException\",\"Message\":\"An exception occurred while executing 'SELECT `fileid`, `storage`, `path`, `parent`, `name`, `mimetype`, `mimepart`, `size`, `mtime`,\\n\\t\\t\\t\\t\\t   `storage_mtime`, `encrypted`, `etag`, `permissions`, `checksum`\\n\\t\\t\\t\\tFROM `oc_filecache` WHERE `storage` = ?

Appreciate there’s not much to work with here, but if they can be made sense of (and possibly improved for NC 11.x or 12? That would be awesome

Can you run tuning-primer.sh or other sql-server-optimization scripts. You can see if you have a large enough cache, enough max_connections, …
Errors could be related, so you have this error every time you move stuff around, or only if it exceeds a certain amount?

JasonBayton · November 20, 2016, 9:46am

The SQL seems random, but the PHP appears to be related to moving files. I’ll try the script.

tflidd · November 20, 2016, 9:51am

And if you are not already using redis as file-locking cache, this reduces considerably the load on your sql database during file operations.

JasonBayton · November 20, 2016, 9:53am

I’m already using Redis, as per my guide

Ok, the script didn’t highlight any issues beyond an index cache. I’ll add that later.

OK, now considering it’s related to sharing, as I got a whole bunch of these testing out the Android Chrome issue in my other thread:

OK, thanks @tflidd. Looks like plenty of people are already working on it.

Not really sure how actively they are following this and if they manage to reproduce this error reliably.
