Detailed Description

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$repoRepository where we should find the path
string$pathPath to file
string$keyKey to store the path and any stashed data under
Exceptions
UploadStashBadPathException
UploadStashFileNotFoundException

Definition at line 41 of file UploadStashFile.php.

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

Member Function Documentation

◆ exists()

UploadStashFile::exists ( )

Definition at line 208 of file UploadStashFile.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

Definition at line 84 of file UploadStashFile.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 191 of file UploadStashFile.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

Definition at line 181 of file UploadStashFile.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 126 of file UploadStashFile.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$thumbNameName 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

Definition at line 98 of file UploadStashFile.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$thumbNameBasename of thumbnail file – however, we don't want to use the file exactly
Returns
string URL to access thumbnail, or URL with partial path

Definition at line 140 of file UploadStashFile.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

Definition at line 166 of file UploadStashFile.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 152 of file UploadStashFile.php.

References $fileKey, and $urlName.

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

◆ remove()

UploadStashFile::remove ( )

Remove the associated temporary file.

Returns
bool Success

Definition at line 199 of file UploadStashFile.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$paramsHandler-specific parameters
int$flagsBitfield that supports THUMB_* constants
Returns
string|null Base name for URL, like '120px-12345.jpg', or null if there is no handler
