| | | | | | | | | | | | "Deadlock DROP/ALTER/CREATE DATABASE with open HANDLER". Fixes production build which was broken by the fix for bug#54360 due to missing instantiation of some Hash_set template's methods. Circumvent requirement of explicit instantiation of non-inline methods by making all Hash_set methods inline.
* A 5.5 version of the fix for Bug #54360 "Deadlock DROP/ALTER/CREATEJon Olav Hauglid2010-07-011-0/+117
DATABASE with open HANDLER" Remove LOCK_create_db, database name locks, and use metadata locks instead. This exposes CREATE/DROP/ALTER DATABASE statements to the graph-based deadlock detector in MDL, and paves the way for a safe, deadlock-free implementation of RENAME DATABASE. Database DDL statements will now take exclusive metadata locks on the database name, while table/view/routine DDL statements take intention exclusive locks on the database name. This prevents race conditions between database DDL and table/view/routine DDL. (e.g. DROP DATABASE with concurrent CREATE/ALTER/DROP TABLE) By adding database name locks, this patch implements WL#4450 "DDL locking: CREATE/DROP DATABASE must use database locks" and WL#4985 "DDL locking: namespace/hierarchical locks". The patch also changes code to use init_one_table() where appropriate. The new lock_table_names() function requires TABLE_LIST::db_length to be set correctly, and this is taken care of by init_one_table(). This patch also adds a simple template to help work with the mysys HASH data structure. Most of the patch was written by Konstantin Osipov.
