Details

migrateActors.php is a maintenance script that migrates actors from pre-1.31 columns to the 'actor' table.

$wgActorTableSchemaMigrationStage needs to be set to MIGRATION_WRITE_NEW or MIGRATION_NEW for the script to do the migration.

The script migrates the following columns:

Table	Primary Key	User Field	Name Field	New column
revision	rev_id	rev_user	rev_user_text	revactor_actor
archive	ar_id	ar_user	ar_user_text	ar_actor
ipblocks	ipb_id	ipb_by	ipb_by_text	ipb_by_actor
image	img_name	img_user	img_user_text	img_actor
oldimage	oi_name, oi_timestamp	oi_user	oi_user_text	oi_actor
filearchive	fa_id	fa_user	fa_user_text	fa_actor
recentchanges	rc_id	rc_user	rc_user_text	rc_actor
logging	log_id	log_user	log_user_text	log_actor

The actors are finally stored in the column actor_name in the actor table.

To improve performance during the run-time of this script, for the table revision, a temporary table named revision_actor_temp is being used during the migration.

This table will be merged with the table revision again in the future.

php migrateActors.php
