Member Function Documentation

◆ doPrepareForOutput()

MediaWiki\Actions\ActionEntryPoint::doPrepareForOutput ( )
protected

Prepare for sending the output.

Should be called by entry points before sending the response. Will be called automatically by run() via prepareForOutput(). Subclasses may override this method, but should not call it directly.

Note
arc-lamp profiling relies on the name of this method, it's hard coded in the arclamp-generate-svgs script!

Reimplemented from MediaWiki\MediaWikiEntryPoint.

Definition at line 207 of file ActionEntryPoint.php.

◆ execute()

MediaWiki\Actions\ActionEntryPoint::execute ( )
protected

Determine and send the response headers and body for this web request.

Reimplemented from MediaWiki\MediaWikiEntryPoint.

Definition at line 88 of file ActionEntryPoint.php.

References $wgTitle, getContext(), getTitle(), Profiler\instance(), and ErrorPageError\report().

◆ getAction()

MediaWiki\Actions\ActionEntryPoint::getAction ( )

Returns the name of the action that will be executed.

Note
This is public for the benefit of extensions that implement the BeforeInitialize or MediaWikiPerformAction hooks.
Returns
string Action

Definition at line 347 of file ActionEntryPoint.php.

◆ getContext()

MediaWiki\Actions\ActionEntryPoint::getContext ( )
protected

Overwritten to narrow the return type to RequestContext.

protected

Definition at line 59 of file ActionEntryPoint.php.

◆ handleTopLevelError()

MediaWiki\Actions\ActionEntryPoint::handleTopLevelError ( Throwable $e)

Subclasses in core may override this to handle errors according to the expected output format. This method is not safe to override for extensions.

Parameters
Throwable$e

◆ initializeArticle()

MediaWiki\Actions\ActionEntryPoint::initializeArticle ( )

References getContext(), and wfWarn().

◆ maybeDoHttpsRedirect()

MediaWiki\Actions\ActionEntryPoint::maybeDoHttpsRedirect ( )
protected

If the stars are suitably aligned, do an HTTP->HTTPS redirect.

Note: Do this after $wgTitle is setup, otherwise the hooks run from isRegistered() will do all sorts of weird stuff.
