Detailed Description

Maintenance script that rebuilds search index table from scratch.

Definition at line 38 of file rebuildtextindex.php.

Constructor & Destructor Documentation

◆ __construct()

RebuildTextIndex::__construct ( )

Default constructor.

Children should call this first if implementing their own constructors

Reimplemented from Maintenance.

Definition at line 46 of file rebuildtextindex.php.

References Maintenance\addDescription().

Member Function Documentation

◆ clearSearchIndex()

RebuildTextIndex::clearSearchIndex ( )
private

Deletes everything from search index.

Definition at line 157 of file rebuildtextindex.php.

References Maintenance\output().

Referenced by execute().

◆ createMysqlTextIndex()

RebuildTextIndex::createMysqlTextIndex ( )
private

(MySQL only) Adds back fulltext index after populating the table.

Definition at line 145 of file rebuildtextindex.php.

References as, and Maintenance\output().

Referenced by execute().

◆ dropMysqlTextIndex()

RebuildTextIndex::dropMysqlTextIndex ( )
private

(MySQL only) Drops fulltext index before populating the table.

Definition at line 133 of file rebuildtextindex.php.

References Maintenance\output().

Referenced by execute().

◆ execute()

RebuildTextIndex::execute ( )

Do the actual work.

All child classes will need to implement this

Returns
bool|null|void True for success, false for failure. Not returning a value, or returning null, is also interpreted as success. Returning false for failure will cause doMaintenance.php to exit the process with a non-zero exit status.

Reimplemented from Maintenance.

References clearSearchIndex(), createMysqlTextIndex(), DB_MASTER, dropMysqlTextIndex(), Maintenance\fatalError(), Maintenance\getDB(), Maintenance\output(), and populateSearchIndex().

◆ getDbType()

RebuildTextIndex::getDbType ( )

Does the script need different DB access? By default, we give Maintenance scripts normal rights to the DB.

Sometimes, a script needs admin rights access for a reason and sometimes they want no access. Subclasses should override and return one of the following values, as needed: Maintenance::DB_NONE - For no DB access at all Maintenance::DB_STD - For normal DB access, default Maintenance::DB_ADMIN - For admin DB access

Returns
int

◆ populateSearchIndex()

RebuildTextIndex::populateSearchIndex ( )
protected

Populates the search index with content from all pages.
