Change Details

A fatal error occurred during `sync-dir` for the 1.27.0-wmf.11 branch, linting files via the PHP 5.5 cli. ``` Fatal error: Cannot redeclare class CallbackFilterIterator in /srv/mediawiki-staging/php-1.27.0-wmf.11/extensions/Echo/includes/iterator/CallbackFilterIterator.php on line 24 Errors parsing /srv/mediawiki-staging/php-1.27.0-wmf.11/extensions/Echo/includes/iterator/CallbackFilterIterator.php ``` It appears this is a shim to provide `CallbackFilterIterator` for PHP implementations that don't yet provide it.
