/data/files_external/rootcerts.crt empty after update

[LukasReschke]

#3470 is back but this time it happens every time after an update via the web updater on c.nc.c.

[LukasReschke]

Looks really odd, the file cache claims the file hasn't been changed since 1475071065 which would be Wed, 28 Sep 2016 13:57:45 GMT 😱

The following error log is also appearing around those times:

{"reqId":"H0v9Bq3mBEShyjFr1N71","level":3,"time":"2017-05-19T20:12:48+00:00","remoteAddr":"","user":"--","app":"PHP","method":"--","url":"--","message":"filemtime(): stat failed for /var/www/html/resources/config/ca-bundle.crt at /var/www/html/lib/private/Security/CertificateManager.php#275","userAgent":"--","version":"12.0.0.23"}

[LukasReschke]

Looking at the server logs when those cases happened I think I see the following similarities on update:

1. Cron seems to have run around that time
2. There are federated shares on this instance
3. The following log messages are in the server log and seem to be from cron:

Let's see if that helps to reproduce this situation somehow.

cron is not supposed to be running in maintenance mode. Or does it? 🙈

cron is not supposed to be running in maintenance mode. Or does it? 🙈

Also what if we check for maintenance mode, see it's disabled and run cron? Then an update is performed while cron is still running (because it does time consuming tasks). Maybe we should check whether it's running, if that's possible at all.

IIRC it creates a lock file in the data dir. It already detects the state itself to prevent running in parallel if the last run did not finish.

[MorrisJobke]

It creates a DB entry - parallel runs are supported and will double the speed to process a tasks ;)

Afaik there since 10 or 11. I guess @nickvergessen worked on this 😉
