Schema Changes

Core

  • array( 'addTable', 'config', 'patch-config.sql' ),
    • Not needed by WMF, probably should be backed out of 1.19
  • array( 'addIndex', 'logging', 'type_action', 'patch-logging-type-action-index.sql'),
  • array( 'doMigrateUserOptions' ),
    • Already done by Roan for Usability
  • array( 'dropField', 'user', 'user_options', 'patch-drop-user_options.sql' ),
    • Would need to be done post deployment (or some changes merged out of 1.19 into 1.18wmf1 to save errors where it is sparsely used
    • Should be postponed to 1.20 deployment
  • array( 'addField', 'revision', 'rev_sha1', 'patch-rev_sha1.sql' ),
  • array( 'addField', 'archive', 'ar_sha1', 'patch-ar_sha1.sql' ),
  • array( 'addIndex', 'page', 'page_redirect_namespace_len', 'patch-page_redirect_namespace_len.sql' ),
  • array( 'modifyField', 'user', 'ug_group', 'patch-ug_group-length-increase.sql' ),
    • Done
  • array( 'addField', 'uploadstash', 'us_chunk_inx', 'patch-uploadstash_chunk.sql' ),
    • Done
  • array( 'addfield', 'job', 'job_timestamp', 'patch-jobs-add-timestamp.sql' ),
    • Done
  • array( 'modifyField', 'user_former_groups', 'ufg_group', 'patch-ufg_group-length-increase.sql' ),
    • Done

Extensions with Schema Updates CentralAuth - AntiSpoof table is already created - Run batchCAAntiSpoof.php to pre-populate AntiSpoof tables CodeReview (only mw.org) CREATE INDEX /*i*/repo_path ON /*_*/code_paths (cp_repo_id, cp_path);

    • done 2/3 -asher

- Can be added any time ArticleFeedback ALTER TABLE article_feedback 

   ADD INDEX aa_page_user_token (aa_page_id, aa_user_text, aa_user_anon_token, aa_revision),
   DROP INDEX aa_user_page_revision;
