In the new one the error message was sometimes different (under LOCK TABLES e.g.), and there were race conditions (if this CREATE happened when a concurrent ALTER has renamed the old table away but haven't put the new table in place) The old one was like "(when using old table names) for DML #mysql50# prefix is optional, for DDL it's required".

Generalized support for auto-updated and/or auto-initialized timestamp and datetime columns. This patch is a reimplementation of MySQL's "WL#5874: CURRENT_TIMESTAMP as DEFAULT for DATETIME columns". In order to ease future merges, this implementation reused few function and variable names from MySQL's patch, however the implementation is quite different. TODO: The only unresolved problem in this patch is the semantics of LOAD DATA for TIMESTAMP and DATETIME columns in the cases when there are missing or NULL columns. I couldn't fully comprehend the logic behind MySQL's behavior and its relationship with their own documentation, so I left the results to be more consistent with all other LOAD cases. The problematic test cases can be seen by running the test file function_defaults, and observing the test case differences. Those were left on purpose for discussion.

breaks SBR This pre-requisite patch refactors the code for dropping tables, used by DROP TABLE and DROP DATABASE. The patch moves the code for acquiring metadata locks out of mysql_rm_table_part2() and makes it the responsibility of the caller. This in preparation of changing the DROP DATABASE implementation to acquire all metadata locks before any changes are made. mysql_rm_table_part2() is renamed mysql_rm_table_no_locks() to reflect the change.

The ALTER PARTITION and SELECT seemed to be deadlocked when having innodb_thread_concurrency = 1. Problem was that there was unreleased latches in the ALTER PARTITION thread which was needed by the SELECT thread to be able to continue. Solution was to release the latches by commit before requesting upgrade to exclusive MDL lock. Updated according to reviewers comments (3). mysql-test/r/partition_innodb.result: updated test result mysql-test/t/partition_innodb.test: added test sql/sql_partition.cc: Moved implicit commit into mysql_change_partition so that if latches are taken, they are always released before waiting on exclusive lock. sql/sql_table.cc: refactored the code to prepare and commit around copy_data_between_tables, to be able to reuse it in mysql_change_partitions sql/sql_table.h: exporting mysql_trans_prepare/commit_alter_copy_data

temp table This patch introduces two key changes in the replication's behavior. Firstly, it reverts part of BUG#51894 which puts any update to temporary tables into the trx-cache. Now, updates to temporary tables are handled according to the type of their engines as a regular table. Secondly, an unsafe mixed statement, (i.e. a statement that access transactional table as well non-transactional or temporary table, and writes to any of them), are written into the trx-cache in order to minimize errors in the execution when the statement logging format is in use. Such changes has a direct impact on which statements are classified as unsafe statements and thus part of BUG#53259 is reverted.

locks on the table Fixing the partitioning specifics after TRUNCATE TABLE in bug-42643 was fixed. Reorganize of code to decrease the size of the giant switch in mysql_execute_command, and to prepare for future parser reengineering. Moved code into Sql_statement objects. Updated patch according to davi's review comments. libmysqld/CMakeLists.txt: Added new files. libmysqld/Makefile.am: Added new files. mysql-test/r/not_partition.result: now returning error on partitioning commands if partitioning is not enabled. mysql-test/r/partition_disabled.result: There is no partition handlerton, so it cannot find the specified engine in the .frm file. mysql-test/r/partition_truncate.result: Updated test results. mysql-test/suite/parts/inc/partition_mgm.inc: Added check that TRUNCATE PARTITION does not delete on failure. mysql-test/suite/parts/r/partition_debug_sync_innodb.result: updated results. mysql-test/suite/parts/r/partition_mgm_lc0_archive.result: updated results. mysql-test/suite/parts/r/partition_mgm_lc1_archive.result: updated results. mysql-test/suite/parts/r/partition_mgm_lc2_archive.result: updated results. mysql-test/suite/parts/t/partition_debug_sync_innodb.test: Test case for this bug. mysql-test/t/not_partition.test: Added check for TRUNCATE PARTITION without partitioning. mysql-test/t/partition_truncate.test: Added test of TRUNCATE PARTITION on non partitioned table. sql/CMakeLists.txt: Added new files. sql/Makefile.am: Added new files. sql/datadict.cc: Moved out the storage engine check into an own function, including assert for lock. sql/datadict.h: added dd_frm_storage_engine. sql/sql_alter_table.cc: moved the code for SQLCOM_ALTER_TABLE in mysql_execute_command into its own file, and using the Sql_statement object to prepare for future parser reengineering. sql/sql_alter_table.h: Created Sql_statement object for ALTER TABLE. sql/sql_lex.cc: resetting m_stmt. sql/sql_lex.h: Temporary hack for forward declaration of enum_alter_table_change_level. sql/sql_parse.cc: Moved out ALTER/ANALYZE/CHECK/OPTIMIZE/REPAIR TABLE from the giant switch into their own Sql_statement objects. sql/sql_parse.h: Exporting check_merge_table_access. sql/sql_partition_admin.cc: created Sql_statement for ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR/TRUNCATE PARTITION. To be able to reuse the TABLE equivalents. sql/sql_partition_admin.h: Added Sql_statement of partition admin statements. sql/sql_table.cc: Moved table maintenance code into sql_table_maintenance.cc sql/sql_table.h: Moved table maintenance code into sql_table_maintenance.h exporting functions used by sql_table_maintenance. sql/sql_table_maintenance.cc: Moved table maintenance code from sql_table.cc sql/sql_table_maintenance.h: Sql_statement objects for ANALYZE/CHECK/OPTIMIZE/REPAIR TABLE. Also declaring the keycache functions. sql/sql_truncate.cc: Moved code from SQLCOM_TRUNCATE in mysql_execute_command into Truncate_statement::execute. Added check for partitioned table on TRUNCATE PARTITION. Moved locking fix for partitioned table into Alter_table_truncate_partition::execute. sql/sql_truncate.h: Truncate_statement declaration (sub class of Sql_statement). sql/sql_yacc.yy: Using the new Sql_statment objects.

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.
