Add check if user is logged-in Otherwise a fatal PHP error is thrown since the filesystem is not setup: ``` ( ! ) Fatal error: Call to a member function getOwner() on null in /Users/lreschke/Programming/core/lib/private/files/filesystem.php on line 817 Call Stack 1 0.0004 247792 {main}( ) ../index.php:0 2 0.0946 5088776 OC::handleRequest( ) ../index.php:28 3 0.1423 7491280 OC\Route\Router->match( ) ../base.php:748 4 0.1664 8592152 call_user_func:{/Users/lreschke/Programming/core/lib/private/route/router.php:250} ( ) ../router.php:250 5 0.1664 8592216 __lambda_func( ) ../router.php:250 6 0.1665 8599064 require_once( '/Users/lreschke/Programming/core/apps/files_versions/ajax/getVersions.php' ) ../route.php(135) : runtime-created function:1 7 0.1801 9061096 OCA\Files_Versions\Storage::getUidAndFilename( ) ../getVersions.php:7 8 0.1801 9061144 OC\Files\Filesystem::getOwner( ) ../storage.php:45 ``` Furthermore this adds the CSRF check as a nice-to-have addition, the requests accessing this are done via the jQuery AJAX methods and thus the header is automatically added to all requests already. 2015-01-09 10:50:17 +00:00			`OCP\JSON::checkLoggedIn();`

Added CSRF checks to files_versions. Expect some error messages - and report them ;) 2012-07-17 09:57:38 +00:00			`OCP\JSON::callCheck();`

Manually type-case all AJAX files This enforces proper types on POST and GET arguments where I considered it sensible. I didn't update some as I don't know what kind of values they would support :see_no_evil: Fixes https://github.com/owncloud/core/issues/14196 for core 2015-02-13 12:33:20 +00:00			`$file = (string)$_GET['file'];`
allow reverting file from history dropdown 2012-05-17 00:16:33 +00:00			`$revision=(int)$_GET['revision'];`

Change files_versions namespace to OCA\Files_Versions 2012-09-19 18:59:57 +00:00			`if(OCA\Files_Versions\Storage::rollback( $file, $revision )) {`
some more clean-up, isVersioned() is no longer needed; rename hook fixed if a complete folder gets renamed 2013-01-11 13:23:28 +00:00			`OCP\JSON::success(array("data" => array( "revision" => $revision, "file" => $file )));`
			`}else{`
Use public api for getting l10n 2014-08-31 08:05:59 +00:00			`$l = \OC::$server->getL10N('files_versions');`
l10n support enhanced in files_versions 2013-02-07 15:34:57 +00:00			`OCP\JSON::error(array("data" => array( "message" => $l->t("Could not revert: %s", array($file) ))));`
