Constructor & Destructor Documentation

◆ __construct()

WikiExporter::__construct	(	$db,
		$history = `self::CURRENT`,
		$buffer = `self::BUFFER`,
		$text = `self::TEXT`
	)

If using WikiExporter::STREAM to stream a large amount of data, provide a database connection which is not managed by LoadBalancer to read from: some history blob types will make additional queries to pull source data while the main query is still running.

Parameters

IDatabase	$db
int \| array	$history	One of WikiExporter::FULL, WikiExporter::CURRENT, WikiExporter::RANGE or WikiExporter::STABLE, or an associative array: offset: non-inclusive offset at which to start the query limit: maximum number of rows to return dir: "asc" or "desc" timestamp order
int	$buffer	One of WikiExporter::BUFFER or WikiExporter::STREAM
int	$text	One of WikiExporter::TEXT or WikiExporter::STUB

Definition at line 94 of file WikiExporter.php.

References $buffer, $text, history, text, and writer.

◆ logsByRange()

WikiExporter::logsByRange	(	$start,
		$end
	)

Parameters

int	$start
int	$end

Definition at line 115 of file WikiExporter.php.

References $output, and writer.

◆ outputLogStream()

WikiExporter::outputLogStream ( $resultset )

protected

Parameters

ResultWrapper $resultset

◆ outputPageStream()

WikiExporter::outputPageStream ( $resultset )

protected

Runs through a query result set dumping page and revision records.

The result set should be sorted/grouped by page to avoid duplicate page records in the output.

Should be safe for streaming (non-buffered) queries, as long as it was made on a separate database connection not managed by LoadBalancer; some blob storage types will make queries to pull source data.

Parameters

ResultWrapper $resultset

◆ pagesByRange()

WikiExporter::pagesByRange	(	$start,
