Call to undefined function OC\Settings\Controller\posix_getuid()

[prudolph81]

Steps to reproduce

1. Make Caldav Request to https:/[cloudhost]/remote.php/dav/
2. Get "undefined function"-error in logfile (see attached), requests dies

Expected behaviour

not to get error, or when error the reqeust should go on
it seems to be an optional check, so the reqeust should not die

Actual behaviour

Browser log is not relevant, I access via caldav

Possible solution:
is it possible to check if the posix funciton posix_getuid (and others) is installed, and do a workaround if not?
Even in the cli tool the error exist. I mean this seems to be an optional check. and on many shared hosters the php posix plugin is not installed but nextcloud runs perfectly.

GitMate.io thinks possibly related issues are #8420 (NC13 - Call to undefined method OC_Defaults::replaceImagePath()), #4756 (Call to undefined method OCA\LookupServerConnector\BackgroundJobs\RetryJob::shouldRun()), #4319 (Call to undefined method OCP\Defaults::shouldReplaceIcons()), #6706 (Call to a member function getUID() on null), and #5059 (Undefined index: federationId).

Which Linux distro are you running?
Seeing this in CentOS right now, never had it on Ubuntu though.

Found the problem. It needed the php-process module installed.
