Manual:$wgMultiContentRevisionSchemaMigrationStage/nl

$wgMultiContentRevisionSchemaMigrationStage geeft de RevisionStore tabel schema migratie fase aan (content, slots, content_models & slot_roles tabellen). De meeste wiki's kunnen dit op  zetten en , het bijbehorende onderhoudsscript, uitvoeren zodra de nodige uitbreidingen zijn geüpdatet.

Merk op dat het lezen van het oude en het nieuwe schema tegelijkertijd niet wordt ondersteund. Pogingen om beide leesbits in te stellen in $wgMultiContentRevisionSchemaMigrationStage zullen resulteren in een InvalidArgumentException.

Details
$wgCommentTableSchemaMigrationStage kan worden ingesteld op één combinatie van de Schema-wisselmigratievlaggen. The allowed value range for the configuration is one of the  constants. The available constants and their planned use cases on Wikimedia Foundation wikis are as follows:


 * (0x03) Only read and write the old schema. The new schema need not even exist. This is used from when the patch is merged until the schema change is actually applied to the database.
 * (0x13): Write both the old and new schema. Read the new schema preferentially, falling back to the old. This is used while the change is being tested, allowing easy roll-back to the old schema.
 * (0x31): Write only the new schema. Read the new schema preferentially, falling back to the old. This is used while running the maintenance script to migrate existing entries in the old schema to the new schema.
 * (0x30): Only read and write the new schema. The old schema (and the feature flag) may now be removed.

For non-Wikimedia Foundation wikis it is recommended to set this to  and to run maintenance/populateContentTables.php in order to take advantage of the new schema.
