wfRandomString( $length=32)
Get a random string containing a number of pseudo-random hex characters.
This is a horrible hack used to keep source compatibility.
resource null $context
Must exists on stream wrapper class.
stream_open( $path, $mode, $options, &$opened_path)
static ImportSource[] $sourceRegistrations
static registerSource(ImportSource $source)
Source interface for XML import.
