------------------------------------------------------------------- revno: 2630.6.6 committer: Konstantin Osipov <konstantin@mysql.com> branch nick: mysql-6.0-3726 timestamp: Tue 2008-05-27 16:15:44 +0400 message: Implement code review fixes for WL#3726 "DDL locking for all metadata objects": cleanup the code from share->mutex acquisitions, which are now obsolete. sql/ha_partition.cc: Rename share->mutex to share->LOCK_ha_data. The mutex never protected the entire share. The right way to protect a share is to acquire an MDL lock. sql/ha_partition.h: Rename share->mutex to share->LOCK_ha_data. sql/sql_base.cc: Remove LOCK_table_share. Do not acquire share->mutex when deleting a table share or incrementing its ref_count. All these operations are and must continue to be protected by LOCK_open and respective MDL locks. sql/sql_view.cc: Remove acquisition of share->mutex when incrementing share->ref_count. sql/table.cc: Simplify release_table_shar() by removing dead code related to share->mutex from it. sql/table.h: Rename TABLE_SHARE::mutex to TABLE_SHARE::LOCK_ha_data to better reflect its purpose. storage/myisam/ha_myisam.cc: Rename share->mutex to share->LOCK_ha_data. |
