- Added a test where ParserOutput objects with CacheTime properties set are unserialized from previous versions. - Generate new serialization tests for 1.38 Now all serialization in production is JSON, so changing property visibility shouldn't affect ParserCache. Bug: T263851 Depends-On: I283340ff559420ceee8f286ba3ef202c01206a23 Change-Id: I70d6feb1c995a0a0f763b21261141ae8ee6dc570

/**
|
|
* Set a page property to be stored in the page_props database table.
|
|
*
|
|
* page_props is a key value store indexed by the page ID. This allows
|
|
* the parser to set a property on a page which can then be quickly
|
|
* retrieved given the page ID or via a DB join when given the page
|
|
* title.
|
|
*
|
|
* Since 1.23, page_props are also indexed by numeric value, to allow
|
|
* for efficient "top k" queries of pages wrt a given property.
|
|
*
|
|
* setPageProperty() is thus used to propagate properties from the parsed
|
|
* page to request contexts other than a page view of the currently parsed
|
|
* article.
|
|
*
|
|
* Some applications examples:
|
|
*
|
|
* * To implement hidden categories, hiding pages from category listings
|
|
* by storing a page property.
|
|
*
|
|
* * Overriding the displayed article title (ParserOutput::setDisplayTitle()).
|
|
*
|
|
* * To implement image tagging, for example displaying an icon on an
|
|
* image thumbnail to indicate that it is listed for deletion on
|
|
* Wikimedia Commons.
|
|
* This is not actually implemented, yet but would be pretty cool.
|
|
*
|
|
* @note Do not use setPageProperty() to set a property which is only used
|
|
* in a context where the ParserOutput object itself is already available,
|
|
* for example a normal page view. There is no need to save such a property
|
|
* in the database since the text is already parsed. You can just hook
|
|
* OutputPageParserOutput and get your data out of the ParserOutput object.
|
|
*
|
|
* If you are writing an extension where you want to set a property in the
|
|
* parser which is used by an OutputPageParserOutput hook, you have to
|
|
* associate the extension data directly with the ParserOutput object.
|
|
* Since MediaWiki 1.21, you can use setExtensionData() to do this:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $parser->getOutput()->setExtensionData( 'my_ext_foo', '...' );
|
|
* @endcode
|
|
*
|
|
* And then later, in OutputPageParserOutput or similar:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $output->getExtensionData( 'my_ext_foo' );
|
|
* @endcode
|
|
*
|
|
* In MediaWiki 1.20 and older, you have to use a custom member variable
|
|
* within the ParserOutput object:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $parser->getOutput()->my_ext_foo = '...';
|
|
* @endcode
|
|
*
|
|
* @note Only scalar values like numbers and strings are supported
|
|
* as a value. Attempt to use an object or array will
|
|
* not work properly with LinksUpdate.
