Public Member Functions inherited from WantedQueryPage

Detailed Description

Querypage that lists the most wanted files.

Definition at line 34 of file SpecialWantedfiles.php.

Constructor & Destructor Documentation

◆ __construct()

WantedFilesPage::__construct ( $name = 'Wantedfiles' )

Definition at line 36 of file SpecialWantedfiles.php.

Member Function Documentation

◆ existenceCheck()

WantedFilesPage::existenceCheck ( Title $title )

protected

Does the file exist?

Use findFile() so we still think file namespace pages without files are missing, but valid file redirects and foreign files are ok.

Parameters

Title $title

Returns: bool

Reimplemented from WantedQueryPage.

Definition at line 108 of file SpecialWantedfiles.php.

References $title.

◆ forceExistenceCheck()

WantedFilesPage::forceExistenceCheck ( )

protected

KLUGE: The results may contain false positives for files that exist e.g.

in a shared repo. Setting this at least keeps them from showing up as redlinks in the output, even if it doesn't fix the real problem (T8220).

Note: could also have existing links here from broken file redirects.

Returns: bool

Reimplemented from WantedQueryPage.

Definition at line 95 of file SpecialWantedfiles.php.

◆ getGroupName()

WantedFilesPage::getGroupName ( )

protected

Under which header this special page is listed in Special:SpecialPages See messages 'specialpages-group-*' for valid names This method defaults to group 'other'.

Stable to override

Returns: string

Since: 1.21

Reimplemented from SpecialPage.

Definition at line 152 of file SpecialWantedfiles.php.

◆ getPageHeader()

WantedFilesPage::getPageHeader ( )

protected

The content returned by this function will be output before any result.

Stable to override

Returns: string

Reimplemented from QueryPage.

Definition at line 40 of file SpecialWantedfiles.php.

References likelyToHaveFalsePositives(), SpecialPage\msg(), NS_CATEGORY, and NS_MAIN.

◆ getQueryInfo()

WantedFilesPage::getQueryInfo ( )

Subclasses return an SQL query here, formatted as an array with the following keys: tables => Table(s) for passing to Database::select() fields => Field(s) for passing to Database::select(), may be * conds => WHERE conditions options => options join_conds => JOIN conditions.

Note that the query itself should return the following three columns: 'namespace', 'title', and 'value'. 'value' is used for sorting.

These may be stored in the querycache table for expensive queries, and that cached data will be returned sometimes, so the presence of extra fields can't be relied upon. The cached 'value' column will be an integer; non-numeric values are useful only for sorting the initial query (except if they're timestamps, see usesTimestamps()).

Don't include an ORDER or LIMIT clause, they will be added.

If this function is not overridden or returns something other than an array, getSQL() will be used instead. This is for backwards compatibility only and is strongly deprecated. Stable to override

Returns: array

Since: 1.18

Reimplemented from QueryPage.

Definition at line 112 of file SpecialWantedfiles.php.

References NS_FILE.

◆ likelyToHaveFalsePositives()

WantedFilesPage::likelyToHaveFalsePositives ( )

protected

Whether foreign repos are likely to cause false positives.

In its own function to allow subclasses to override.

See also: SpecialWantedFilesGUOverride in GlobalUsage extension.

Since: 1.24

Returns: bool
