Member Function Documentation

SpecialUploadStash::execute ( $ subPage )

Execute page -- can output a file directly or show a listing of them.

Parameters:

$subPage String: subpage, e.g. in http://example.com/wiki/Special:UploadStash/foo.jpg, the "foo.jpg" part

Returns:: Boolean: success

Reimplemented from SpecialPage.

Output HTTP response of raw content Side effect: writes HTTP response to STDOUT.

Parameters:

String	$content,:	content
String	$mimeType,:	mime type

Output headers for streaming XXX unsure about encoding as binary; if we received from HTTP perhaps we should use that encoding, concatted with semicolon to mimeType as it usually is.

Side effect: preps PHP to write headers to STDOUT.

Parameters:

String	$contentType	: string suitable for content-type header
String	$size,:	length in bytes

SpecialUploadStash::outputLocalFile ( File $ file ) [private]

Output HTTP response for file Side effect: writes HTTP response to STDOUT.

Parameters:

$file File object with a local path (e.g. UnregisteredLocalFile, LocalFile. Oddly these don't share an ancestor!)

Scale a file (probably with a locally installed imagemagick, or similar) and output it to STDOUT.

Parameters:

$file,:	File object
$params,:	scaling parameters ( e.g. array( width => '50' ) );
$flags,:	scaling flags ( see File:: constants )

Here is the caller graph for this function:

SpecialUploadStash::outputRemoteScaledThumb	(	$	file,
		$	params,
		$	flags
	)		`[private]`

Scale a file with a remote "scaler", as exists on the Wikimedia Foundation cluster, and output it to STDOUT.

Note: unlike the usual thumbnail process, the web client never sees the cluster URL; we do the whole HTTP transaction to the scaler ourselves and cat the results out. Note: We rely on NFS to have propagated the file contents to the scaler. However, we do not rely on the thumbnail being created in NFS and then propagated back to our filesystem. Instead we take the results of the HTTP request instead. Note: no caching is being done here, although we are instructing the client to cache it forever.

Parameters:
