I noticed in fluorine:/a/mw-log/apache2.log Jan 4 06:34:46 mw1202: PHP Warning: array_shift() expects parameter 1 to be array, null given in /usr/local/apache/common-local/php-1.23wmf9/extensions/Flow/includes/Repository/TreeRepository.php on line 230 Jan 4 06:34:46 mw1202: PHP Warning: header() expects parameter 3 to be long, string given in /usr/local/apache/common-local/php-1.23wmf9/includes/WebResponse.php on line 38 The first line seems familiar, but I can't find other examples. The second has happened on ee-flow, but weeks ago: 9:[Sun Dec 22 21:17:15 2013] [error] [client 130.60.206.75] PHP Warning: header() expects parameter 3 to be long, string given in /srv/mediawiki/includes/WebResponse.php on line 38, referer: http://ee-flow.wmflabs.org/wiki/Talk:Flow_bugs 10:[Sun Dec 22 21:18:09 2013] [error] [client 130.60.206.75] PHP Warning: header() expects parameter 3 to be long, string given in /srv/mediawiki/includes/WebResponse.php on line 38, referer: http://ee-flow.wmflabs.org/wiki/Talk:Flow_bugs The header() method's third parameter is * @param $http_response_code null|int Forces the HTTP response code to the specified value. Maybe a failed API request or other failure is returning a string and not 500 or whatever. It could be ParsoidUtils.php returning Parsoid's $response... We should configure labs servers to spew PHP Warnings to the screen.
