HASH_TABLE_SYNC_MUTEX was kind-of used for the adaptive hash index, even though that hash table is already protected by btr_search_latches[]. HASH_TABLE_SYNC_RWLOCK was only being used for buf_pool.page_hash. It is cleaner to decouple that synchronization from hash_table_t, and move it to the actual user. buf_pool_t::page_hash_latches[]: Synchronization for buf_pool.page_hash. LATCH_ID_HASH_TABLE_MUTEX: Remove. hash_table_t::sync_obj, hash_table_t::n_sync_obj: Remove. hash_table_t::type, hash_table_sync_t: Remove. HASH_ASSERT_OWN(), hash_get_mutex(), hash_get_nth_mutex(): Remove. ib_recreate(): Merge to the only caller, buf_pool_resize_hash(). ib_create(): Merge to the callers. ha_clear(): Merge to the only caller buf_pool_t::close(). buf_pool_t::create(): Merge the ib_create() and hash_create_sync_obj() invocations. ha_insert_for_fold_func(): Clarify an assertion. buf_pool_t::page_hash_lock(): Simplify the logic. hash_assert_can_search(), hash_assert_can_modify(): Remove. These predicates were only being invoked for the adaptive hash index, while they only are effective for buf_pool.page_hash. HASH_DELETE_AND_COMPACT(): Merge to ha_delete_hash_node(). hash_get_sync_obj_index(): Remove. hash_table_t::heaps[], hash_get_nth_heap(): Remove. It was actually unused! hash_get_heap(): Remove. It was only used in ha_delete_hash_node(), where we always use hash_table_t::heap. hash_table_t::calc_hash(): Replaces hash_calc_hash(). |

MariaDB: The open source relational database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/

Help
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss, MariaDB's Zulip instance, https://mariadb.zulipchat.com/ and the #maria IRC channel on Freenode.
Live QA for beginner contributors
MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip and IRC. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions they’d like, and a live developer will be available to assist.
New contributors can ask questions any time, but we will provide immediate feedback during that interval.
Licensing
NOTE:
MariaDB is specifically available only under version 2 of the GNU General Public License (GPLv2). (I.e. Without the "any later version" clause.) This is inherited from MySQL. Please see the README file in the MySQL distribution for more information.
