Remove error display on productive systems and use log file instead

[netAction]

OwnCloud Version: 6.0

Expected behaviour: OwnCloud should never show error messages to users.

Current behaviour: OwnCloud needs setup in Apache VirtualHost directive.

php_flag display_errors off

Which platform are you using?
on all my Debian installations I never had to add this configuration.

[netAction]

Ubuntu 13.10.

Error messages (even warnings and notices) are shown in HTML by default on most PHP installations.

I also never had this on openSUSE 13.1.
Can this be disabled per .htaccess somehow ?
Or can we set that config from within the PHP code ?

[netAction]

Are you really sure PHP errors will not be visible to users? What happes when you add some nonsense to index.php?

Maybe this is a solution:

ini_set('display_errors','Off');

[PVince81]

Just checked and php.ini in openSUSE 13.1 has this by default:

display_errors = Off

Looks like using ini_set could work: http://stackoverflow.com/a/15949445

@netAction I think this is the responsibility of the server admin to configure php properly. We shouldn't try to override server settings from the application side. ownCloud doesn't know if this is a production, development or a debugging server.

[netAction]

Dropping errors as HTML to the browser is never a good idea. There already is an internal error log. If you do not like this you could build a new one.

In my oppinion, every server could be sometimes used for debugging, too.

[PVince81]

Should we update the documentation instead and tell people to disable error display ?
Note that when disabled in php.ini, errors will still be logged in owncloud.log or the server's error log.

Closing this as this should be the responsibility of the server admin. - It's even documented on the PHP documentation: http://php.net/manual/en/errorfunc.configuration.php#ini.display-errors
