Public Member Functions
	__construct ( $repo, $path, $key)
	A LocalFile wrapper around a file that has been temporarily stashed, so we can do things like create thumbnails for it.
	exists ()
	Returns true if file exists in the repository.
	getDescriptionUrl ()
	A method needed by the file transforming and scaling routines in File.php We do not necessarily care about doing the description at this point However, we also can't return the empty string, as the rest of MediaWiki demands this (and calls to imagemagick convert require it to be there)
	getFileKey ()
	Getter for file key (the unique id by which this file's location & metadata is stored in the db)
	getFullUrl ()
	Parent classes use this method, for no obvious reason, to return the path (relative to wiki root, I assume).
	getThumbPath ( $thumbName=false)
	Get the path for the thumbnail (actually any transformation of this file) The actual argument is the result of thumbName although we seem to have buggy code elsewhere that expects a boolean 'suffix'.
	getThumbUrl ( $thumbName=false)
	Get a URL to access the thumbnail This is required because the model of how files work requires that the thumbnail urls be predictable.
	getUrl ()
	Return the URL of the file, if for some reason we wanted to download it We tend not to do this for the original file, but we do want thumb icons.
	getUrlName ()
	The basename for the URL, which we want to not be related to the filename.
	remove ()
	Remove the associated temporary file.
	thumbName ( $params, $flags=0)
	Return the file/url base name of a thumbnail with the specified parameters.

Constructor & Destructor Documentation

__construct()

UploadStashFile::__construct	(		$repo,
			$path,
			$key
	)

A LocalFile wrapper around a file that has been temporarily stashed, so we can do things like create thumbnails for it.

Arguably UnregisteredLocalFile should be handling its own file repo but that class is a bit retarded currently.

Parameters

FileRepo	$repo	Repository where we should find the path
string	$path	Path to file
string	$key	Key to store the path and any stashed data under

Exceptions

UploadStashBadPathException
UploadStashFileNotFoundException

Definition at line 570 of file UploadStash.php.

References UnregisteredLocalFile\$path, File\$repo, FileRepo\fileExists(), FileRepo\getZonePath(), FileRepo\isVirtualUrl(), name, FileRepo\resolveVirtualUrl(), FileRepo\validateFilename(), and wfDebug().

Member Function Documentation

exists()

UploadStashFile::exists

(

)

Returns true if file exists in the repository.

Overridden by LocalFile to avoid unnecessary stat calls.

Returns

bool Whether file exists in the repository.

Reimplemented from File.

Definition at line 733 of file UploadStash.php.

getDescriptionUrl()

UploadStashFile::getDescriptionUrl

(

)

A method needed by the file transforming and scaling routines in File.php We do not necessarily care about doing the description at this point However, we also can't return the empty string, as the rest of MediaWiki demands this (and calls to imagemagick convert require it to be there)

Returns

string Dummy value

Reimplemented from File.

Definition at line 609 of file UploadStash.php.

References getUrl().

getFileKey()

UploadStashFile::getFileKey

(

)

Getter for file key (the unique id by which this file's location & metadata is stored in the db)

Returns

string File key

Definition at line 716 of file UploadStash.php.

References $fileKey.

getFullUrl()

UploadStashFile::getFullUrl

(

)

Parent classes use this method, for no obvious reason, to return the path (relative to wiki root, I assume).

But with this class, the URL is unrelated to the path.

Returns

string Url

Reimplemented from File.

Definition at line 706 of file UploadStash.php.

References getUrl().

getSpecialUrl()

UploadStashFile::getSpecialUrl (   $subPage )

private

Helper function – given a 'subpage', return the local URL, e.g.

/wiki/Special:UploadStash/subpage

Parameters

string

$subPage

Returns

string Local URL for this subpage in the Special:UploadStash space.

Definition at line 651 of file UploadStash.php.

References SpecialPage\getTitleFor().

Referenced by getThumbUrl(), and getUrl().

getThumbPath()

UploadStashFile::getThumbPath

(

$thumbName = false

)

Get the path for the thumbnail (actually any transformation of this file) The actual argument is the result of thumbName although we seem to have buggy code elsewhere that expects a boolean 'suffix'.

Parameters

string

$thumbName

Name of thumbnail (e.g. "120px-123456.jpg" ), or false to just get the path

Returns

string Path thumbnail should take on filesystem, or containing directory if thumbname is false

Reimplemented from File.

Definition at line 623 of file UploadStash.php.

References UnregisteredLocalFile\$path.

getThumbUrl()

UploadStashFile::getThumbUrl

(

$thumbName = false

)

Get a URL to access the thumbnail This is required because the model of how files work requires that the thumbnail urls be predictable.

However, in our model the URL is not based on the filename (that's hidden in the db)

Parameters

string

$thumbName

Basename of thumbnail file – however, we don't want to use the file exactly

Returns

string URL to access thumbnail, or URL with partial path

Reimplemented from File.

Definition at line 665 of file UploadStash.php.

References getSpecialUrl(), getUrlName(), and wfDebug().

getUrl()

UploadStashFile::getUrl

(

)

Return the URL of the file, if for some reason we wanted to download it We tend not to do this for the original file, but we do want thumb icons.

Returns

string Url

Reimplemented from File.

Definition at line 691 of file UploadStash.php.

References $url, getSpecialUrl(), and getUrlName().

Referenced by getDescriptionUrl(), and getFullUrl().

getUrlName()

UploadStashFile::getUrlName

(

)

The basename for the URL, which we want to not be related to the filename.

Will also be used as the lookup key for a thumbnail file.

Returns

string Base url name, like '120px-123456.jpg'

Definition at line 677 of file UploadStash.php.

References $fileKey, and $urlName.

Referenced by getThumbUrl(), getUrl(), and thumbName().

remove()

UploadStashFile::remove

(

)

Remove the associated temporary file.

Returns

status Success

Definition at line 724 of file UploadStash.php.

thumbName()

UploadStashFile::thumbName	(		$params,
			$flags = 0
	)

Return the file/url base name of a thumbnail with the specified parameters.

We override this because we want to use the pretty url name instead of the ugly file name.

Parameters

array	$params	Handler-specific parameters
int	$flags	Bitfield that supports THUMB_* constants

Returns

string|null Base name for URL, like '120px-12345.jpg', or null if there is no handler

Reimplemented from File.

Definition at line 641 of file UploadStash.php.
