Constructor & Destructor Documentation

◆ __construct()

PopulateArchiveRevId::__construct ( )

Default constructor.

Children should call this first if implementing their own constructors

Reimplemented from LoggedUpdateMaintenance.

Member Function Documentation

◆ checkMysqlAutoIncrementBug()

static PopulateArchiveRevId::checkMysqlAutoIncrementBug ( IDatabase  $dbw)

Check for (and work around) a MySQL auto-increment bug.

(T202032) MySQL until 8.0 and MariaDB until some version after 10.1.34 don't save the auto-increment value to disk, so on server restart it might reuse IDs from deleted revisions. We can fix that with an insert with an explicit rev_id value, if necessary.

◆ doDBUpdates()

PopulateArchiveRevId::doDBUpdates ( )

Do the actual work.

All child classes will need to implement this. Return true to log the update as done or false (usually on failure).

◆ makeDummyRevisionRow()

static PopulateArchiveRevId::makeDummyRevisionRow ( IDatabase  $dbw)

Construct a dummy revision table row to use for reserving IDs.

The row will have a wildly unlikely timestamp, and possibly a generic user and comment, but will otherwise be derived from a revision on the wiki's main page or some other revision in the database.
