Change Details

Once all code has been ported to use the new MCR schema, B/C code for the legacy schema should be removed: * remove support for pre-MCR schema from RevisionStore, WikiPage, and related classes * remove $wgMultiContentRevisionSchemaMigrationStage variable This requires the removal of all references to rev_text_id and ar_rev_id, and any other direct access to the legacy schema, in the code base //(including extensions)//.

Once all code has been ported to use the new MCR schema, B/C code for writing the legacy schema should be removed: * remove support for writing pre-MCR schema from RevisionStore, WikiPage, and related classes * move support for reading pre-MCR schema out of RevisionStore and friends, into code that is specific to the update process. We'll probably need to keep it there forever, but there is no reason to have it in the main code base. * remove $wgMultiContentRevisionSchemaMigrationStage variable. We should probably still have code that checks if that variable is set to something other than READ_NEW | WRITE_NEW. In that case, MediaWiki should fail with a meaningful error message, telling the wiki's owner to update the schema. This requires the removal of all references to rev_text_id and ar_rev_id, and any other direct access to the legacy schema, in the code base //(including extensions)//.
