Changing field::field_name and Item::name to LEX_CSTRING
Benefits of this patch: - Removed a lot of calls to strlen(), especially for field_string - Strings generated by parser are now const strings, less chance of accidently changing a string - Removed a lot of calls with LEX_STRING as parameter (changed to pointer) - More uniform code - Item::name_length was not kept up to date. Now fixed - Several bugs found and fixed (Access to null pointers, access of freed memory, wrong arguments to printf like functions) - Removed a lot of casts from (const char*) to (char*) Changes: - This caused some ABI changes - lex_string_set now uses LEX_CSTRING - Some fucntions are now taking const char* instead of char* - Create_field::change and after changed to LEX_CSTRING - handler::connect_string, comment and engine_name() changed to LEX_CSTRING - Checked printf() related calls to find bugs. Found and fixed several errors in old code. - A lot of changes from LEX_STRING to LEX_CSTRING, especially related to parsing and events. - Some changes from LEX_STRING and LEX_STRING & to LEX_CSTRING* - Some changes for char* to const char* - Added printf argument checking for my_snprintf() - Introduced null_clex_str, star_clex_string, temp_lex_str to simplify code - Added item_empty_name and item_used_name to be able to distingush between items that was given an empty name and items that was not given a name This is used in sql_yacc.yy to know when to give an item a name. - select table_name."*' is not anymore same as table_name.* - removed not used function Item::rename() - Added comparision of item->name_length before some calls to my_strcasecmp() to speed up comparison - Moved Item_sp_variable::make_field() from item.h to item.cc - Some minimal code changes to avoid copying to const char * - Fixed wrong error message in wsrep_mysql_parse() - Fixed wrong code in find_field_in_natural_join() where real_item() was set when it shouldn't - ER_ERROR_ON_RENAME was used with extra arguments. - Removed some (wrong) ER_OUTOFMEMORY, as alloc_root will already give the error. TODO: - Check possible unsafe casts in plugin/auth_examples/qa_auth_interface.c - Change code to not modify LEX_CSTRING for database name (as part of lower_case_table_names) |

Fixed bug#12546938 (formerly known as 61005) - CREATE IF NOT EXIST EVENT
will create multiple running events. A CREATE IF NOT EXIST on an event that existed and was enabled caused multiple instances of the event to run. Disabling the event didn't help. If the event was dropped, the event stopped running, but when created again, multiple instances of the event were still running. The only way to get out of this situation was to restart the server. The problem was that Event_db_repository::create_event() didn't return enough information to discriminate between situation when event didn't exist and was created and when event did exist and was not created (but a warning was emitted). As result in the latter case event was added to in-memory queue of events second time. And this led to unwarranted multiple executions of the same event. The solution is to add out-parameter to Event_db_repository::create_event() method which will signal that event was not created because it already exists and so it should not be added to the in-memory queue. mysql-test/r/events_bugs.result: Added results for test for Bug#12546938. mysql-test/t/events_bugs.test: Added test for Bug#12546938. sql/event_db_repository.cc: Event_db_repository::create_event was modified: set newly added out-parameter event_already_exists to true value if event wasn't created because event already existed and IF NOT EXIST clause was present. sql/event_db_repository.h: Added out-parameter 'event_already_exists' to create_event() method. sql/events.cc: Events::create_event was modified: insert new element into event queue only if event was actually created. |

Patch that refactors global read lock implementation and fixes
bug #57006 "Deadlock between HANDLER and FLUSH TABLES WITH READ LOCK" and bug #54673 "It takes too long to get readlock for 'FLUSH TABLES WITH READ LOCK'". The first bug manifested itself as a deadlock which occurred when a connection, which had some table open through HANDLER statement, tried to update some data through DML statement while another connection tried to execute FLUSH TABLES WITH READ LOCK concurrently. What happened was that FTWRL in the second connection managed to perform first step of GRL acquisition and thus blocked all upcoming DML. After that it started to wait for table open through HANDLER statement to be flushed. When the first connection tried to execute DML it has started to wait for GRL/the second connection creating deadlock. The second bug manifested itself as starvation of FLUSH TABLES WITH READ LOCK statements in cases when there was a constant stream of concurrent DML statements (in two or more connections). This has happened because requests for protection against GRL which were acquired by DML statements were ignoring presence of pending GRL and thus the latter was starved. This patch solves both these problems by re-implementing GRL using metadata locks. Similar to the old implementation acquisition of GRL in new implementation is two-step. During the first step we block all concurrent DML and DDL statements by acquiring global S metadata lock (each DML and DDL statement acquires global IX lock for its duration). During the second step we block commits by acquiring global S lock in COMMIT namespace (commit code acquires global IX lock in this namespace). Note that unlike in old implementation acquisition of protection against GRL in DML and DDL is semi-automatic. We assume that any statement which should be blocked by GRL will either open and acquires write-lock on tables or acquires metadata locks on objects it is going to modify. For any such statement global IX metadata lock is automatically acquired for its duration. The first problem is solved because waits for GRL become visible to deadlock detector in metadata locking subsystem and thus deadlocks like one in the first bug become impossible. The second problem is solved because global S locks which are used for GRL implementation are given preference over IX locks which are acquired by concurrent DML (and we can switch to fair scheduling in future if needed). Important change: FTWRL/GRL no longer blocks DML and DDL on temporary tables. Before this patch behavior was not consistent in this respect: in some cases DML/DDL statements on temporary tables were blocked while in others they were not. Since the main use cases for FTWRL are various forms of backups and temporary tables are not preserved during backups we have opted for consistently allowing DML/DDL on temporary tables during FTWRL/GRL. Important change: This patch changes thread state names which are used when DML/DDL of FTWRL is waiting for global read lock. It is now either "Waiting for global read lock" or "Waiting for commit lock" depending on the stage on which FTWRL is. Incompatible change: To solve deadlock in events code which was exposed by this patch we have to replace LOCK_event_metadata mutex with metadata locks on events. As result we have to prohibit DDL on events under LOCK TABLES. This patch also adds extensive test coverage for interaction of DML/DDL and FTWRL. Performance of new and old global read lock implementations in sysbench tests were compared. There were no significant difference between new and old implementations. mysql-test/include/check_ftwrl_compatible.inc: Added helper script which allows to check that a statement is compatible with FLUSH TABLES WITH READ LOCK. mysql-test/include/check_ftwrl_incompatible.inc: Added helper script which allows to check that a statement is incompatible with FLUSH TABLES WITH READ LOCK. mysql-test/include/handler.inc: Adjusted test case to the fact that now DROP TABLE closes open HANDLERs for the table to be dropped before checking if there active FTWRL in this connection. mysql-test/include/wait_show_condition.inc: Fixed small error in the timeout message. The correct name of variable used as parameter for this script is "$condition" and not "$wait_condition". mysql-test/r/delayed.result: Added test coverage for scenario which triggered assert in metadata locking subsystem. mysql-test/r/events_2.result: Updated test results after prohibiting event DDL operations under LOCK TABLES. mysql-test/r/flush.result: Added test coverage for bug #57006 "Deadlock between HANDLER and FLUSH TABLES WITH READ LOCK". mysql-test/r/flush_read_lock.result: Added test coverage for various aspects of FLUSH TABLES WITH READ LOCK functionality. mysql-test/r/flush_read_lock_kill.result: Adjusted test case after replacing custom global read lock implementation with one based on metadata locks. Use new debug_sync point. Do not disable concurrent inserts as now InnoDB we always use InnoDB table. mysql-test/r/handler_innodb.result: Adjusted test case to the fact that now DROP TABLE closes open HANDLERs for the table to be dropped before checking if there active FTWRL in this connection. mysql-test/r/handler_myisam.result: Adjusted test case to the fact that now DROP TABLE closes open HANDLERs for the table to be dropped before checking if there active FTWRL in this connection. mysql-test/r/mdl_sync.result: Adjusted test case after replacing custom global read lock implementation with one based on metadata locks. Replaced usage of GRL-specific debug_sync's with appropriate sync points in MDL subsystem. mysql-test/suite/perfschema/r/dml_setup_instruments.result: Updated test results after removing global COND_global_read_lock condition variable. mysql-test/suite/perfschema/r/func_file_io.result: Ensure that this test doesn't affect subsequent tests. At the end of its execution enable back P_S instrumentation which this test disables at some point. mysql-test/suite/perfschema/r/func_mutex.result: Ensure that this test doesn't affect subsequent tests. At the end of its execution enable back P_S instrumentation which this test disables at some point. mysql-test/suite/perfschema/r/global_read_lock.result: Adjusted test case to take into account that new GRL implementation is based on MDL. mysql-test/suite/perfschema/r/server_init.result: Adjusted test case after replacing custom global read lock implementation with one based on MDL and replacing LOCK_event_metadata mutex with metadata lock. mysql-test/suite/perfschema/t/func_file_io.test: Ensure that this test doesn't affect subsequent tests. At the end of its execution enable back P_S instrumentation which this test disables at some point. mysql-test/suite/perfschema/t/func_mutex.test: Ensure that this test doesn't affect subsequent tests. At the end of its execution enable back P_S instrumentation which this test disables at some point. mysql-test/suite/perfschema/t/global_read_lock.test: Adjusted test case to take into account that new GRL implementation is based on MDL. mysql-test/suite/perfschema/t/server_init.test: Adjusted test case after replacing custom global read lock implementation with one based on MDL and replacing LOCK_event_metadata mutex with metadata lock. mysql-test/suite/rpl/r/rpl_tmp_table_and_DDL.result: Updated test results after prohibiting event DDL under LOCK TABLES. mysql-test/t/delayed.test: Added test coverage for scenario which triggered assert in metadata locking subsystem. mysql-test/t/events_2.test: Updated test case after prohibiting event DDL operations under LOCK TABLES. mysql-test/t/flush.test: Added test coverage for bug #57006 "Deadlock between HANDLER and FLUSH TABLES WITH READ LOCK". mysql-test/t/flush_block_commit.test: Adjusted test case after changing thread state name which is used when COMMIT waits for FLUSH TABLES WITH READ LOCK from "Waiting for release of readlock" to "Waiting for commit lock". mysql-test/t/flush_block_commit_notembedded.test: Adjusted test case after changing thread state name which is used when DML waits for FLUSH TABLES WITH READ LOCK. Now we use "Waiting for global read lock" in this case. mysql-test/t/flush_read_lock.test: Added test coverage for various aspects of FLUSH TABLES WITH READ LOCK functionality. mysql-test/t/flush_read_lock_kill-master.opt: We no longer need to use make_global_read_lock_block_commit_loop debug tag in this test. Instead we rely on an appropriate debug_sync point in MDL code. mysql-test/t/flush_read_lock_kill.test: Adjusted test case after replacing custom global read lock implementation with one based on metadata locks. Use new debug_sync point. Do not disable concurrent inserts as now InnoDB we always use InnoDB table. mysql-test/t/lock_multi.test: Adjusted test case after changing thread state names which are used when DML or DDL waits for FLUSH TABLES WITH READ LOCK to "Waiting for global read lock". mysql-test/t/mdl_sync.test: Adjusted test case after replacing custom global read lock implementation with one based on metadata locks. Replaced usage of GRL-specific debug_sync's with appropriate sync points in MDL subsystem. Updated thread state names which are used when DDL waits for FTWRL. mysql-test/t/trigger_notembedded.test: Adjusted test case after changing thread state names which are used when DML or DDL waits for FLUSH TABLES WITH READ LOCK to "Waiting for global read lock". sql/event_data_objects.cc: Removed Event_queue_element::status/last_executed_changed members and Event_queue_element::update_timing_fields() method. We no longer use this class for updating mysql.events once event is chosen for execution. Accesses to instances of this class in scheduler thread require protection by Event_queue::LOCK_event_queue mutex and we try to avoid updating table while holding this lock. sql/event_data_objects.h: Removed Event_queue_element::status/last_executed_changed members and Event_queue_element::update_timing_fields() method. We no longer use this class for updating mysql.events once event is chosen for execution. Accesses to instances of this class in scheduler thread require protection by Event_queue::LOCK_event_queue mutex and we try to avoid updating table while holding this lock. sql/event_db_repository.cc: - Changed Event_db_repository methods to not release all metadata locks once they are done updating mysql.events table. This allows to keep metadata lock protecting against GRL and lock protecting particular event around until corresponding DDL statement is written to the binary log. - Removed logic for conditional update of "status" and "last_executed" fields from update_timing_fields_for_event() method. In the only case when this method is called now "last_executed" is always modified and tracking change of "status" is too much hassle. sql/event_db_repository.h: Removed logic for conditional update of "status" and "last_executed" fields from Event_db_repository:: update_timing_fields_for_event() method. In the only case when this method is called now "last_executed" is always modified and tracking change of "status" field is too much hassle. sql/event_queue.cc: Changed event scheduler code not to update mysql.events table while holding Event_queue::LOCK_event_queue mutex. Doing so led to a deadlock with a new GRL implementation. This deadlock didn't occur with old implementation due to fact that code acquiring protection against GRL ignored pending GRL requests (which lead to GRL starvation). One of goals of new implementation is to disallow GRL starvation and so we have to solve problem with this deadlock in a different way. sql/events.cc: Changed methods of Events class to acquire protection against GRL while perfoming DDL statement and keep it until statement is written to the binary log. Unfortunately this step together with new GRL implementation exposed deadlock involving Events::LOCK_event_metadata and GRL. To solve it Events::LOCK_event_metadata mutex was replaced with a metadata lock on event. As a side-effect events DDL has to be prohibited under LOCK TABLES even in cases when mysql.events table was explicitly locked for write. sql/events.h: Replaced Events::LOCK_event_metadata mutex with a metadata lock on event. sql/ha_ndbcluster.cc: Updated code after replacing custom global read lock implementation with one based on MDL. Since MDL subsystem should now be able to detect deadlocks involving metadata locks and GRL there is no need for special handling of active GRL. sql/handler.cc: Replaced custom implementation of global read lock with one based on metadata locks. Consequently when doing commit instead of calling method of Global_read_lock class to acquire protection against GRL we simply acquire IX in COMMIT namespace. sql/lock.cc: Replaced custom implementation of global read lock with one based on metadata locks. This step allows to expose wait for GRL to deadlock detector of MDL subsystem and thus succesfully resolve deadlocks similar to one behind bug #57006 "Deadlock between HANDLER and FLUSH TABLES WITH READ LOCK". It also solves problem with GRL starvation described in bug #54673 "It takes too long to get readlock for 'FLUSH TABLES WITH READ LOCK'" since metadata locks used by GRL give preference to FTWRL statement instead of DML statements (if needed in future this can be changed to fair scheduling). Similar to old implementation of acquisition of GRL is two-step. During the first step we block all concurrent DML and DDL statements by acquiring global S metadata lock (each DML and DDL statement acquires global IX lock for its duration). During the second step we block commits by acquiring global S lock in COMMIT namespace (commit code acquires global IX lock in this namespace). Note that unlike in old implementation acquisition of protection against GRL in DML and DDL is semi-automatic. We assume that any statement which should be blocked by GRL will either open and acquires write-lock on tables or acquires metadata locks on objects it is going to modify. For any such statement global IX metadata lock is automatically acquired for its duration. To support this change: - Global_read_lock::lock/unlock_global_read_lock and make_global_read_lock_block_commit methods were changed accordingly. - Global_read_lock::wait_if_global_read_lock() and start_waiting_global_read_lock() methods were dropped. It is now responsibility of code acquiring metadata locks opening tables to acquire protection against GRL by explicitly taking global IX lock with statement duration. - Global variables, mutex and condition variable used by old implementation was removed. - lock_routine_name() was changed to use statement duration for its global IX lock. It was also renamed to lock_object_name() as it now also used to take metadata locks on events. - Global_read_lock::set_explicit_lock_duration() was added which allows not to release locks used for GRL when leaving prelocked mode. sql/lock.h: - Renamed lock_routine_name() to lock_object_name() and changed its signature to allow its usage for events. - Removed broadcast_refresh() function. It is no longer needed with new GRL implementation. sql/log_event.cc: Release metadata locks with statement duration at the end of processing legacy event for LOAD DATA. This ensures that replication thread processing such event properly releases its protection against global read lock. sql/mdl.cc: Changed MDL subsystem to support new MDL-based implementation of global read lock. Added COMMIT and EVENTS namespaces for metadata locks. Changed thread state name for GLOBAL namespace to "Waiting for global read lock". Optimized MDL_map::find_or_insert() method to avoid taking m_mutex mutex when looking up MDL_lock objects for GLOBAL or COMMIT namespaces. We keep pre-created MDL_lock objects for these namespaces around and simply return pointers to these global objects when needed. Changed MDL_lock/MDL_scoped_lock to properly handle notification of insert delayed handler threads when FTWRL takes global S lock. Introduced concept of lock duration. In addition to locks with transaction duration which work in the way which is similar to how locks worked before (i.e. they are released at the end of transaction), locks with statement and explicit duration were introduced. Locks with statement duration are automatically released at the end of statement. Locks with explicit duration require explicit release and obsolete concept of transactional sentinel. * Changed MDL_request and MDL_ticket classes to support notion of duration. * Changed MDL_context to keep locks with different duration in different lists. Changed code handling ticket list to take this into account. * Changed methods responsible for releasing locks to take into account duration of tickets. Particularly public MDL_context::release_lock() method now only can release tickets with explicit duration (there is still internal method which allows to specify duration). To release locks with statement or transaction duration one have to use release_statement/transactional_locks() methods. * Concept of savepoint for MDL subsystem now has to take into account locks with statement duration. Consequently MDL_savepoint class was introduced and methods working with savepoints were updated accordingly. * Added methods which allow to set duration for one or all locks in the context. sql/mdl.h: Changed MDL subsystem to support new MDL-based implementation of global read lock. Added COMMIT and EVENTS namespaces for metadata locks. Introduced concept of lock duration. In addition to locks with transaction duration which work in the way which is similar to how locks worked before (i.e. they are released at the end of transaction), locks with statement and explicit duration were introduced. Locks with statement duration are automatically released at the end of statement. Locks with explicit duration require explicit release and obsolete concept of transactional sentinel. * Changed MDL_request and MDL_ticket classes to support notion of duration. * Changed MDL_context to keep locks with different duration in different lists. Changed code handling ticket list to take this into account. * Changed methods responsible for releasing locks to take into account duration of tickets. Particularly public MDL_context::release_lock() method now only can release tickets with explicit duration (there is still internal method which allows to specify duration). To release locks with statement or transaction duration one have to use release_statement/transactional_locks() methods. * Concept of savepoint for MDL subsystem now has to take into account locks with statement duration. Consequently MDL_savepoint class was introduced and methods working with savepoints were updated accordingly. * Added methods which allow to set duration for one or all locks in the context. sql/mysqld.cc: Removed global mutex and condition variables which were used by old implementation of GRL. Also we no longer need to initialize Events::LOCK_event_metadata mutex as it was replaced with metadata locks on events. sql/mysqld.h: Removed global variable, mutex and condition variables which were used by old implementation of GRL. sql/rpl_rli.cc: When slave thread closes tables which were open for handling of RBR events ensure that it releases global IX lock which was acquired as protection against GRL. sql/sp.cc: Adjusted code to the new signature of lock_object/routine_name(), to the fact that one now needs specify duration of lock when initializing MDL_request and to the fact that savepoints for MDL subsystem are now represented by MDL_savepoint class. sql/sp_head.cc: Ensure that statements in stored procedures release statement metadata locks and thus release their protectiong against GRL in proper moment in time. Adjusted code to the fact that one now needs specify duration of lock when initializing MDL_request. sql/sql_admin.cc: Adjusted code to the fact that one now needs specify duration of lock when initializing MDL_request. sql/sql_base.cc: - Implemented support for new approach to acquiring protection against global read lock. We no longer acquire such protection explicitly on the basis of statement flags. Instead we always rely on code which is responsible for acquiring metadata locks on object to be changed acquiring this protection. This is achieved by acquiring global IX metadata lock with statement duration. Code doing this also responsible for checking that current connection has no active GRL by calling an Global_read_lock::can_acquire_protection() method. Changed code in open_table() and lock_table_names() accordingly. Note that as result of this change DDL and DML on temporary tables is always compatible with GRL (before it was incompatible in some cases and compatible in other cases). - To speed-up code acquiring protection against GRL introduced m_has_protection_against_grl member in Open_table_context class. It indicates that protection was already acquired sometime during open_tables() execution and new attempts can be skipped. - Thanks to new GRL implementation calls to broadcast_refresh() became unnecessary and were removed. - Adjusted code to the fact that one now needs specify duration of lock when initializing MDL_request and to the fact that savepoints for MDL subsystem are now represented by MDL_savepoint class. sql/sql_base.h: Adjusted code to the fact that savepoints for MDL subsystem are now represented by MDL_savepoint class. Also introduced Open_table_context::m_has_protection_against_grl member which allows to avoid acquiring protection against GRL while opening tables if such protection was already acquired. sql/sql_class.cc: Changed THD::leave_locked_tables_mode() after transactional sentinel for metadata locks was obsoleted by introduction of locks with explicit duration. sql/sql_class.h: - Adjusted code to the fact that savepoints for MDL subsystem are now represented by MDL_savepoint class. - Changed Global_read_lock class according to changes in global read lock implementation: * wait_if_global_read_lock and start_waiting_global_read_lock are now gone. Instead code needing protection against GRL has to acquire global IX metadata lock with statement duration itself. To help it new can_acquire_protection() was introduced. Also as result of the above change m_protection_count member is gone too. * Added m_mdl_blocks_commits_lock member to store metadata lock blocking commits. * Adjusted code to the fact that concept of transactional sentinel was obsoleted by concept of lock duration. - Removed CF_PROTECT_AGAINST_GRL flag as it is no longer necessary. New GRL implementation acquires protection against global read lock automagically when statement acquires metadata locks on tables or other objects it is going to change. sql/sql_db.cc: Adjusted code to the fact that one now needs specify duration of lock when initializing MDL_request. sql/sql_handler.cc: Removed call to broadcast_refresh() function. It is no longer needed with new GRL implementation. Adjusted code after introducing duration concept for metadata locks. Particularly to the fact transactional sentinel was replaced with explicit duration. sql/sql_handler.h: Renamed mysql_ha_move_tickets_after_trans_sentinel() to mysql_ha_set_explicit_lock_duration() after transactional sentinel was obsoleted by locks with explicit duration. sql/sql_insert.cc: Adjusted code handling delaying inserts after switching to new GRL implementation. Now connection thread initiating delayed insert has to acquire global IX lock in addition to metadata lock on table being inserted into. This IX lock protects against GRL and similarly to SW lock on table being inserted into has to be passed to handler thread in order to avoid deadlocks. sql/sql_lex.cc: LEX::protect_against_global_read_lock member is no longer necessary since protection against GRL is automatically taken by code acquiring metadata locks/opening tables. sql/sql_lex.h: LEX::protect_against_global_read_lock member is no longer necessary since protection against GRL is automatically taken by code acquiring metadata locks/opening tables. sql/sql_parse.cc: - Implemented support for new approach to acquiring protection against global read lock. We no longer acquire such protection explicitly on the basis of statement flags. Instead we always rely on code which is responsible for acquiring metadata locks on object to be changed acquiring this protection. This is achieved by acquiring global IX metadata lock with statement duration. This lock is automatically released at the end of statement execution. - Changed implementation of CREATE/DROP PROCEDURE/FUNCTION not to release metadata locks and thus protection against of GRL in the middle of statement execution. - Adjusted code to the fact that one now needs specify duration of lock when initializing MDL_request and to the fact that savepoints for MDL subsystem are now represented by MDL_savepoint class. sql/sql_prepare.cc: Adjusted code to the to the fact that savepoints for MDL subsystem are now represented by MDL_savepoint class. sql/sql_rename.cc: With new GRL implementation there is no need to explicitly acquire protection against GRL before renaming tables. This happens automatically in code which acquires metadata locks on tables being renamed. sql/sql_show.cc: Adjusted code to the fact that one now needs specify duration of lock when initializing MDL_request and to the fact that savepoints for MDL subsystem are now represented by MDL_savepoint class. sql/sql_table.cc: - With new GRL implementation there is no need to explicitly acquire protection against GRL before dropping tables. This happens automatically in code which acquires metadata locks on tables being dropped. - Changed mysql_alter_table() not to release lock on new table name explicitly and to rely on automatic release of locks at the end of statement instead. This was necessary since now MDL_context::release_lock() is supported only for locks for explicit duration. sql/sql_trigger.cc: With new GRL implementation there is no need to explicitly acquire protection against GRL before changing table triggers. This happens automatically in code which acquires metadata locks on tables which triggers are to be changed. sql/sql_update.cc: Fix bug exposed by GRL testing. During prepare phase acquire only S metadata locks instead of SW locks to keep prepare of multi-UPDATE compatible with concurrent LOCK TABLES WRITE and global read lock. sql/sql_view.cc: With new GRL implementation there is no need to explicitly acquire protection against GRL before creating view. This happens automatically in code which acquires metadata lock on view to be created. sql/sql_yacc.yy: LEX::protect_against_global_read_lock member is no longer necessary since protection against GRL is automatically taken by code acquiring metadata locks/opening tables. sql/table.cc: Adjusted code to the fact that one now needs specify duration of lock when initializing MDL_request. sql/table.h: Adjusted code to the fact that one now needs specify duration of lock when initializing MDL_request. sql/transaction.cc: Replaced custom implementation of global read lock with one based on metadata locks. Consequently when doing commit instead of calling method of Global_read_lock class to acquire protection against GRL we simply acquire IX in COMMIT namespace. Also adjusted code to the fact that MDL savepoint is now represented by MDL_savepoint class. |

A pre-requisite patch for the fix for Bug#52044.
This patch also fixes Bug#55452 "SET PASSWORD is replicated twice in RBR mode". The goal of this patch is to remove the release of metadata locks from close_thread_tables(). This is necessary to not mistakenly release the locks in the course of a multi-step operation that involves multiple close_thread_tables() or close_tables_for_reopen(). On the same token, move statement commit outside close_thread_tables(). Other cleanups: Cleanup COM_FIELD_LIST. Don't call close_thread_tables() in COM_SHUTDOWN -- there are no open tables there that can be closed (we leave the locked tables mode in THD destructor, and this close_thread_tables() won't leave it anyway). Make open_and_lock_tables() and open_and_lock_tables_derived() call close_thread_tables() upon failure. Remove the calls to close_thread_tables() that are now unnecessary. Simplify the back off condition in Open_table_context. Streamline metadata lock handling in LOCK TABLES implementation. Add asserts to ensure correct life cycle of statement transaction in a session. Remove a piece of dead code that has also become redundant after the fix for Bug 37521. mysql-test/r/variables.result: Update results: set @@autocommit and statement transaction/ prelocked mode. mysql-test/r/view.result: A harmless change in CHECK TABLE <view> status for a broken view. If previously a failure to prelock all functions used in a view would leave the connection in LTM_PRELOCKED mode, now we call close_thread_tables() from open_and_lock_tables() and leave prelocked mode, thus some check in mysql_admin_table() that works only in prelocked/locked tables mode is no longer activated. mysql-test/suite/rpl/r/rpl_row_implicit_commit_binlog.result: Fixed Bug#55452 "SET PASSWORD is replicated twice in RBR mode": extra binlog events are gone from the binary log. mysql-test/t/variables.test: Add a test case: set autocommit and statement transaction/prelocked mode. sql/event_data_objects.cc: Simplify code in Event_job_data::execute(). Move sp_head memory management to lex_end(). sql/event_db_repository.cc: Move the release of metadata locks outside close_thread_tables(). Make sure we call close_thread_tables() when open_and_lock_tables() fails and remove extra code from the events data dictionary. Use close_mysql_tables(), a new internal function to properly close mysql.* tables in the data dictionary. Contract Event_db_repository::drop_events_by_field, drop_schema_events into one function. When dropping all events in a schema, make sure we don't mistakenly release all locks acquired by DROP DATABASE. These include locks on the database name and the global intention exclusive metadata lock. sql/event_db_repository.h: Function open_event_table() does not require an instance of Event_db_repository. sql/events.cc: Use close_mysql_tables() instead of close_thread_tables() to bootstrap events, since the latter no longer releases metadata locks. sql/ha_ndbcluster.cc: - mysql_rm_table_part2 no longer releases acquired metadata locks. Do it in the caller. sql/ha_ndbcluster_binlog.cc: Deploy the new protocol for closing thread tables in run_query() and ndb_binlog_index code. sql/handler.cc: Assert that we never call ha_commit_trans/ ha_rollback_trans in sub-statement, which is now the case. sql/handler.h: Add an accessor to check whether THD_TRANS object is empty (has no transaction started). sql/log.cc: Update a comment. sql/log_event.cc: Since now we commit/rollback statement transaction in mysql_execute_command(), we need a mechanism to communicate from Query_log_event::do_apply_event() to mysql_execute_command() that the statement transaction should be rolled back, not committed. Ideally it would be a virtual method of THD. I hesitate to make THD a virtual base class in this already large patch. Use a thd->variables.option_bits for now. Remove a call to close_thread_tables() from the slave IO thread. It doesn't open any tables, and the protocol for closing thread tables is more complicated now. Make sure we properly close thread tables, however, in Load_data_log_event, which doesn't follow the standard server execution procedure with mysql_execute_command(). @todo: this piece should use Server_runnable framework instead. Remove an unnecessary call to mysql_unlock_tables(). sql/rpl_rli.cc: Update Relay_log_info::slave_close_thread_tables() to follow the new close protocol. sql/set_var.cc: Remove an unused header. sql/slave.cc: Remove an unnecessary call to close_thread_tables(). sql/sp.cc: Remove unnecessary calls to close_thread_tables() from SP DDL implementation. The tables will be closed by the caller, in mysql_execute_command(). When dropping all routines in a database, make sure to not mistakenly drop all metadata locks acquired so far, they include the scoped lock on the schema. sql/sp_head.cc: Correct the protocol that closes thread tables in an SP instruction. Clear lex->sphead before cleaning up lex with lex_end to make sure that we don't delete the sphead twice. It's considered to be "cleaner" and more in line with future changes than calling delete lex->sphead in other places that cleanup the lex. sql/sp_head.h: When destroying m_lex_keeper of an instruction, don't delete the sphead that all lex objects share. @todo: don't store a reference to routine's sp_head instance in instruction's lex. sql/sql_acl.cc: Don't call close_thread_tables() where the caller will do that for us. Fix Bug#55452 "SET PASSWORD is replicated twice in RBR mode" by disabling RBR replication in change_password() function. Use close_mysql_tables() in bootstrap and ACL reload code to make sure we release all metadata locks. sql/sql_base.cc: This is the main part of the patch: - remove manipulation with thd->transaction and thd->mdl_context from close_thread_tables(). Now this function is only responsible for closing tables, nothing else. This is necessary to be able to easily use close_thread_tables() in procedures, that involve multiple open/close tables, which all need to be protected continuously by metadata locks. Add asserts ensuring that TABLE object is only used when is protected by a metadata lock. Simplify the back off condition of Open_table_context, we no longer need to look at the autocommit mode. Make open_and_lock_tables() and open_normal_and_derived_tables() close thread tables and release metadata locks acquired so-far upon failure. This simplifies their usage. Implement close_mysql_tables(). sql/sql_base.h: Add declaration for close_mysql_tables(). sql/sql_class.cc: Remove a piece of dead code that has also become redundant after the fix for Bug 37521. The code became dead when my_eof() was made a non-protocol method, but a method that merely modifies the diagnostics area. The code became redundant with the fix for Bug#37521, when we started to cal close_thread_tables() before Protocol::end_statement(). sql/sql_do.cc: Do nothing in DO if inside a substatement (the assert moved out of trans_rollback_stmt). sql/sql_handler.cc: Add comments. sql/sql_insert.cc: Remove dead code. Release metadata locks explicitly at the end of the delayed insert thread. sql/sql_lex.cc: Add destruction of lex->sphead to lex_end(), lex "reset" method called at the end of each statement. sql/sql_parse.cc: Move close_thread_tables() and other related cleanups to mysql_execute_command() from dispatch_command(). This has become possible after the fix for Bug#37521. Mark federated SERVER statements as DDL. Next step: make sure that we don't store eof packet in the query cache, and move the query cache code outside mysql_parse. Brush up the code of COM_FIELD_LIST. Remove unnecessary calls to close_thread_tables(). When killing a query, don't report "OK" if it was a suicide. sql/sql_parse.h: Remove declaration of a function that is now static. sql/sql_partition.cc: Remove an unnecessary call to close_thread_tables(). sql/sql_plugin.cc: open_and_lock_tables() will clean up after itself after a failure. Move close_thread_tables() above end: label, and replace with close_mysql_tables(), which will also release the metadata lock on mysql.plugin. sql/sql_prepare.cc: Now that we no longer release locks in close_thread_tables() statement prepare code has become more straightforward. Remove the now redundant check for thd->killed() (used only by the backup project) from Execute_server_runnable. Reorder code to take into account that now mysql_execute_command() performs lex->unit.cleanup() and close_thread_tables(). sql/sql_priv.h: Add a new option to server options to interact between the slave SQL thread and execution framework (hack). @todo: use a virtual method of class THD instead. sql/sql_servers.cc: Due to Bug 25705 replication of DROP/CREATE/ALTER SERVER is broken. Make sure at least we do not attempt to replicate these statements using RBR, as this violates the assert in close_mysql_tables(). sql/sql_table.cc: Do not release metadata locks in mysql_rm_table_part2, this is done by the caller. Do not call close_thread_tables() in mysql_create_table(), this is done by the caller. Fix a bug in DROP TABLE under LOCK TABLES when, upon error in wait_while_table_is_used() we would mistakenly release the metadata lock on a non-dropped table. Explicitly release metadata locks when doing an implicit commit. sql/sql_trigger.cc: Now that we delete lex->sphead in lex_end(), zero the trigger's sphead in lex after loading the trigger, to avoid double deletion. sql/sql_udf.cc: Use close_mysql_tables() instead of close_thread_tables(). sql/sys_vars.cc: Remove code added in scope of WL#4284 which would break when we perform set @@session.autocommit along with setting other variables and using tables or functions. A test case added to variables.test. sql/transaction.cc: Add asserts. sql/tztime.cc: Use close_mysql_tables() rather than close_thread_tables(). |

Patch for the following bugs:
- BUG#11986: Stored routines and triggers can fail if the code
has a non-ascii symbol
- BUG#16291: mysqldump corrupts string-constants with non-ascii-chars
- BUG#19443: INFORMATION_SCHEMA does not support charsets properly
- BUG#21249: Character set of SP-var can be ignored
- BUG#25212: Character set of string constant is ignored (stored routines)
- BUG#25221: Character set of string constant is ignored (triggers)
There were a few general problems that caused these bugs:
1. Character set information of the original (definition) query for views,
triggers, stored routines and events was lost.
2. mysqldump output query in client character set, which can be
inappropriate to encode definition-query.
3. INFORMATION_SCHEMA used strings with mixed encodings to display object
definition;
1. No query-definition-character set.
In order to compile query into execution code, some extra data (such as
environment variables or the database character set) is used. The problem
here was that this context was not preserved. So, on the next load it can
differ from the original one, thus the result will be different.
The context contains the following data:
- client character set;
- connection collation (character set and collation);
- collation of the owner database;
The fix is to store this context and use it each time we parse (compile)
and execute the object (stored routine, trigger, ...).
2. Wrong mysqldump-output.
The original query can contain several encodings (by means of character set
introducers). The problem here was that we tried to convert original query
to the mysqldump-client character set.
Moreover, we stored queries in different character sets for different
objects (views, for one, used UTF8, triggers used original character set).
The solution is
- to store definition queries in the original character set;
- to change SHOW CREATE statement to output definition query in the
binary character set (i.e. without any conversion);
- introduce SHOW CREATE TRIGGER statement;
- to dump special statements to switch the context to the original one
before dumping and restore it afterwards.
Note, in order to preserve the database collation at the creation time,
additional ALTER DATABASE might be used (to temporary switch the database
collation back to the original value). In this case, ALTER DATABASE
privilege will be required. This is a backward-incompatible change.
3. INFORMATION_SCHEMA showed non-UTF8 strings
The fix is to generate UTF8-query during the parsing, store it in the object
and show it in the INFORMATION_SCHEMA.
Basically, the idea is to create a copy of the original query convert it to
UTF8. Character set introducers are removed and all text literals are
converted to UTF8.
This UTF8 query is intended to provide user-readable output. It must not be
used to recreate the object. Specialized SHOW CREATE statements should be
used for this.
The reason for this limitation is the following: the original query can
contain symbols from several character sets (by means of character set
introducers).
Example:
- original query:
CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1;
- UTF8 query (for INFORMATION_SCHEMA):
CREATE VIEW v1 AS SELECT 'Hello' AS c1;

A set of changes aiming to make the Event Scheduler more user-friendly
when there are no up-to-date system tables to support it: - initialize the scheduler before reporting "Ready for connections". This ensures that warnings, if any, are printed before "Ready for connections", and this message is not mangled. - do not abort the scheduler if there are no system tables - check the tables once at start up, remember the status and disable the scheduler if the tables are not up to date. If one attempts to use the scheduler with bad tables, issue an error message. - clean up the behaviour of the module under LOCK TABLES and pre-locking mode - make sure implicit commit of Events DDL works as expected. - add more tests Collateral clean ups in the events code. This patch fixes Bug#23631 Events: SHOW VARIABLES doesn't work when mysql.event is damaged mysql-test/r/events.result: Update results. mysql-test/r/events_bugs.result: Update results. mysql-test/r/events_restart_phase1.result: Update results. mysql-test/r/events_restart_phase2.result: Update results. mysql-test/r/events_restart_phase3.result: Update results. mysql-test/r/events_scheduling.result: Update results. mysql-test/r/events_time_zone.result: Update results. mysql-test/t/events.test: Add new tests for tampering with mysql.event and some more tests for sub-statements, LOCK TABLES mode and pre-locking. mysql-test/t/events_bugs.test: Move the non-concurrent part of test for Bug 16420 to this file. mysql-test/t/events_restart_phase1.test: Rewrite events_restart_* tests to take into account that now we check mysql.event table only once, at server startup. mysql-test/t/events_restart_phase2.test: Rewrite events_restart_* tests to take into account that now we check mysql.event table only once, at server startup. mysql-test/t/events_restart_phase3.test: Rewrite events_restart_* tests to take into account that now we check mysql.event table only once, at server startup. mysql-test/t/events_scheduling.test: Add more coverage for event_scheduler global variable. mysql-test/t/events_time_zone.test: Move the non-concurrent part of the tests for Bug 16420 to events_bugs.test sql/event_data_objects.cc: Move update_timing_fields functionality to Event_db_repository. Make loading of events from a table record more robust to tampering with the table - now we do not check mysql.event on every table open. sql/event_data_objects.h: Cleanup. sql/event_db_repository.cc: Now Event_db_repository is responsible for table I/O only. All the logic of events DDL is handled outside, in Events class please refer to the added test coverage to see how this change affected the behavior of Event Scheduler. Dependency on sp_head.h and sp.h removed. Make this module robust to tweaks with mysql.event table. Move check_system_tables from events.cc to this file sql/event_db_repository.h: Cleanup declarations (remove unused ones, change return type to bool from int). sql/event_queue.cc: Update to adapt to the new start up scheme of the Event Scheduler. sql/event_queue.h: Cleanup declarations. sql/event_scheduler.cc: Make all the error messages uniform: [SEVERITY] Event Scheduler: [user][schema.event] message Using append_identifier for error logging was an overkill - we may need it only if the system character set may have NUL (null character) as part of a valid identifier, this is currently never the case, whereas additional quoting did not look nice in the log. sql/event_scheduler.h: Cleanup the headers. sql/events.cc: Use a different start up procedure of Event Scheduler: - at start up, try to check the system tables first. If they are not up-to-date, disable the scheduler. - try to load all the active events. In case of a load error, abort start up. - do not parse an event on start up. Parsing only gives some information about event validity, but far not all. Consolidate the business logic of Events DDL in this module. Now opt_event_scheduler may change after start up and thus is protected by LOCK_event_metadata mutex. sql/events.h: Use all-static-data-members approach to implement Singleton pattern. sql/mysqld.cc: New invocation scheme of Events. Move some logic to events.cc. Initialize the scheduler before reporting "Ready for connections". sql/set_var.cc: Clean up sys_var_thd_sql_mode::symbolic_mode_representation to work with a LEX_STRING. Move more logic related to @@events_scheduler global variable to Events module. sql/set_var.h: Update declarations. sql/share/errmsg.txt: If someone tampered with mysql.event table after the server has started we no longer give him/her a complete report what was actually broken. Do not send the user to look at the error log in such case, as there is nothing there (check_table_intact is not executed). sql/sp_head.cc: Update to a new declaration of sys_var_thd_sql_mode::symbolic_mode_representation sql/sql_db.cc: New invocation scheme of Events module. sql/sql_parse.cc: Move more logic to Events module. Make sure that we are consistent in the way access rights are checked for Events DDL: always after committing the current transaction and checking the system tables. sql/sql_show.cc: Update to the new declarations of sys_var_thd_sql_mode::symbolic_mode_representation sql/sql_test.cc: New invocation scheme of events. sql/table.cc: mysql.event is a system table. Update check_table_intact to be concurrent, more verbose, and less smart. sql/table.h: Add a helper method. mysql-test/r/events_trans.result: New BitKeeper file ``mysql-test/r/events_trans.result'' mysql-test/t/events_trans.test: New BitKeeper file ``mysql-test/t/events_trans.test'': test cases for Event Scheduler that require a transactional storage engine. |

BUG#16420: Events: timestamps become UTC
BUG#26429: SHOW CREATE EVENT is incorrect for an event that
STARTS NOW()
BUG#26431: Impossible to re-create an event from backup if its
STARTS clause is in the past
WL#3698: Events: execution in local time zone
The problem was that local times specified by the user in AT, STARTS
and ENDS of CREATE EVENT/ALTER EVENT statement were converted to UTC,
and the original time zone was forgotten. This way, event scheduler
couldn't honor Daylight Saving Time shifts, and times shown to the
user were also in UTC. Additionally, CREATE EVENT didn't allow times
in the past, thus preventing straightforward event restoration from
old backups.
This patch reworks event scheduler time computations, performing them
in the time zone associated with the event. Also it allows times to
be in the past.
The patch adds time_zone column to mysql.event table.
NOTE: The patch is almost final, but the bug#9953 should be pushed
first.
client/mysqldump.c:
Before every CREATE EVENT, output its time zone.
mysql-test/include/wait_condition.inc:
Add optional $wait_timeout parameter.
mysql-test/lib/init_db.sql:
Add time_zone column.
mysql-test/r/events.result:
Update result.
mysql-test/r/events_bugs.result:
Update result.
mysql-test/r/events_grant.result:
Update result.
mysql-test/r/events_restart_phase1.result:
Update result.
mysql-test/r/events_scheduling.result:
Update result.
mysql-test/r/mysqldump.result:
Update result.
mysql-test/r/ps.result:
Update result.
mysql-test/r/system_mysql_db.result:
Update result.
mysql-test/t/events.test:
Remove STARTS from the result, as it depends on current time.
mysql-test/t/events_bugs.test:
Time in the past is no longer an error.
mysql-test/t/events_restart_phase1.test:
Fill new column 'time_zone' in mysql.event.
mysql-test/t/events_scheduling.test:
Cleanup: disable event scheduler.
scripts/mysql_create_system_tables.sh:
Add new column 'time_zone' to mysql.event.
scripts/mysql_fix_privilege_tables.sql:
Add new column 'time_zone' to mysql.event.
sql/event_data_objects.cc:
The essence of the change is the following:
- for internal times use my_time_t instead of TIME. Assignment and
comparison is done now on plain numbers.
- in init_execute_at(), init_starts(), init_ends() convert given time
to number of seconds since Epoch (aka Unix time, in UTC).
- handle time_zone field loading and storing.
- in get_next_time(), Unix time is converted back to event time zone,
interval is added, and the result is converted to UTC again.
- fix Event_timed::get_create_event() to report STARTS and ENDS.
- before executing the event body we set thread time zone to the
event time zone.
sql/event_data_objects.h:
Add time_zone member to Event_basic class.
Store internal times in my_time_t (number of seconds since Epoch),
rather than in broken down TIME structure.
sql/event_db_repository.cc:
Add time_zone column handling.
Give a warning and do not create an event if its execution time is in
the past, and ON COMPLETION NOT PRESERVE is set, because such an event
should be dropped by that time. Also, do not allow ALTER EVENT to
set execution time in the past when ON COMPLETION NOT PRESERVE is set.
sql/event_db_repository.h:
Add enum member for new time zone column.
sql/event_queue.cc:
Replace handling of broken down times with simple handling of
my_time_t.
sql/event_queue.h:
Store internal times in my_time_t (number of seconds since Epoch),
rather than in broken down TIME structure.
sql/event_scheduler.cc:
Add TODO comment.
sql/events.cc:
Send time_zone column for SHOW CREATE EVENT.
sql/share/errmsg.txt:
Update error message, and add two more errors.
sql/sql_show.cc:
Add TIME_ZONE column to the output of SHOW EVENTS.
mysql-test/r/events_time_zone.result:
BitKeeper file /home/tomash/src/mysql_ab/mysql-5.1-wl3698/mysql-test/r/events_time_zone.result

WL#3629 - Replication of Invocation and Invoked Features
This changeset adds replication of events and user-defined functions.
There are several bug reports involved in this change:
BUG#16421, BUG#17857, BUG#20384:
This patch modifies the mysql.events table to permit the addition of
another enum value for the status column. The column now has values
of ('DISABLED','SLAVESIDE_DISABLED','ENABLED'). A status of
SLAVESIDE_DISABLED is set on the slave during replication of events.
This enables users to determine which events werereplicated from the
master and to later enable them if they promote the slave to a master.
The CREATE, ALTER, and DROP statements are binlogged.
A new test was added for replication of events (rpl_events).
BUG#17671:
This patch modifies the code to permit logging of user-defined functions.
Note: this is the CREATE FUNCTION ... SONAME variety. A more friendly error
message to be displayed should a replicated user-defined function not be
found in the loadable library or if the library is missing from the
slave.The CREATE andDROP statements are binlogged. A new test was added
for replication of user-defined functions (rpl_udf).
The patch also adds a new column to the mysql.event table named
'originator' that is used to store the server_id of the server that
the event originated on. This enables users to promote a slave to a
master and later return the promoted slave to a slave and disable the
replicated events.
mysql-test/lib/init_db.sql:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the SLAVESIDE_DISABLED to the list of enumerated
values for the mysql.event table.
This patch adds the column 'originator' to the mysql.event table.
mysql-test/r/events.result:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the 'originator' column to the events test results.
This was necessary to ensure the manual insert into mysql.event table
succeeds because the originator column is set to NOT NULL.
mysql-test/r/events_grant.result:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the 'originator' column to the events_grant test results.
This was necessary to ensure the manual insert into mysql.event table
succeeds because the originator column is set to NOT NULL.
mysql-test/r/events_restart_phase1.result:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the 'originator' column to the events_restart_phase1
test results. This was necessary to ensure the manual insert into
mysql.event table succeeds because the originator column is set to
NOT NULL.
mysql-test/r/system_mysql_db.result:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the SLAVESIDE_DISABLED to the list of enumerated
values for the mysql.event table.

These changes to the result file were necessary to ensure correct test
results.
mysql-test/t/events.test:
WL#3629 - Replication of Invocation and Invoked Feature
This patch adds the 'originator' column to the events
test. This was necessary to ensure the manual insert into
mysql.event table succeeds because the originator column is set to
NOT NULL.

WL#3337 (Event scheduler new architecture)
Post-review fixes. Mostly whitespace, int-to-bool return value, fixed comments
sql/Makefile.am:
compile all submodules of Events before compiling the facade
sql/event_data_objects.cc:
- Use initialization list
- Clean whitespaces
- Shorten comments
- Fix comments
sql/event_data_objects.h:
- Fix whitespace
sql/event_db_repository.cc:
- Change return type from int to bool where only one error code is
returned.
- Don't use macros but get the maximal number of characters in a column
from the column
- Fix comments
- Make functions which has return value but it's not used - void.
sql/event_db_repository.h:
- Methods with only one error code int -> bool return value
- Remove declaration of fill_schema_events, a function that does not exist
sql/event_queue.cc:
- Use initialization lists
- Let find_n_remove_event delete the object thus making the code more robust.
The caller could forget to destruct the object. In addition, find_n_remove_element()
does not return a value.
- Move check_system_tables() to class Events
- Fix comments
sql/event_queue.h:
- Whitespace changes
- init_queue() should allow passing of THD
- check_system_tables moved to class Events
- find_n_remove_event() is now void
sql/event_scheduler.cc:
- Initialize res before use
- Remove end stop from message
sql/event_scheduler.h:
Add uninitialized state. The scheduler is in it before init_scheduler()
is called. The rationale is that otherwise state has no value before
the call. If the system tables were damaged the scheduler won't be initialized
but in Events::deinit() Event_scheduler::stop() will be called and this will
touch state, generating valgrind warning at minimum.
sql/events.cc:
- Whitespace changes
- Fix comments
- Make methods which have only one error code be bool instead of int
- Create temporarily a THD to be used for the initialization of Event_queue
- Event_queue::check_system_tables() moved to Events::check_system_tables
- is_started() is renamed to is_execution_of_events_started()
sql/events.h:
- Whitespace changes
- When a method returns only one error code it should be bool, not int
- is_started() renamed to is_execution_of_events_started()
sql/set_var.cc:
is_started() is renamed to is_execution_of_events_started()
sql/sql_db.cc:
The return code is not used, thus don't return anything and drop_schema_events()
is now void.
sql/sql_yacc.yy:
- Fix comments
- Remove unneeded initialization which is performed in lex_init()
sql/share/errmsg.txt:
New error message
sql/table.cc:
- Fix comments
- make table_check_intact() accespt const *table_def
sql/table.h:
Make table_check_intact() accespt const *table_def

This patch introduces specialized Event data objects Event_basic as parent. Event_queue_element used for queue storage Event_timed used for SHOW EVENTS/ I_S.EVENTS / SHOW CREATE EVENT Event_job_data using during execution. Methods were moved out of Event_timed to other classes. This patch also introduces Events::LOCK_event_metadata. This patch gives new implementation of Events::dump_internal_status(). Now both the Event_scheduler and Event_queue return information during their ::dump_internal_status().

WL#3337 (Event scheduler new architecture)
Cleaned up the code a bit. Fixed few leaks. This code still does not load events on server startup from disk. The problem is that there is a need for a THD instance, which does not exist during server boot. This will be solved soon. Still Event_timed is used both for the memory queue and for exectution. This will be changed according to WL#3337 probably in the next commit. sql/event_data_objects.cc: Strip unneeded stuff from class Event_timed Event_timed is still used for the queue and execution. That will be changed in the next commit. sql/event_data_objects.h: Strip unneeded stuff from class Event_timed Event_timed is still used for the queue and execution. That will be changed in the next commit. sql/event_db_repository.cc: Cosmetics. Add a new method load_named_event_job, to be made complete in the next commit. It will load from disk an instance of Event_job_data to be used during execution. sql/event_db_repository.h: find_event does not need MEM_ROOT anymore because the memory is allocated on Event's own root. sql/event_queue.cc: Remove dead code. Move dumping of the queue to separate method. Make critical sections in create_event & update_event as small as possible - load the new event outside of the section and free the object also outside of it. sql/event_queue.h: init -> init_queue -> easier for ctags deinit -> deinit_queue -> easier for ctags sql/event_scheduler.cc: empty this file sql/event_scheduler.h: empty this file sql/event_scheduler_ng.cc: add back DBUG_RETURN(0) in thread handlers. We don't stop running events when stopping the scheduler. Therefore remove this method now. If it is needed later it can be added back. sql/event_scheduler_ng.h: Remove stop_all_running_threads() init -> init_scheduler deinit -> deinit_scheduler easier for ctags sql/events.cc: Cosmetics sql/events.h: Cosmetics sql/set_var.cc: Remove references to dead code sql/sql_parse.cc: Reorganize a bit. |

This is the first cut of separating Event_scheduler in two classes which are more specialized. Inheritance was used to separate methods and member variables. Still Event_scheduler is a child of Event_queue. This dependency will be removed soon. sql/event_data_objects.cc: add comments sql/event_db_repository.cc: coding style sql/event_db_repository.h: add a call, will be implemented later sql/event_queue.cc: Event_queue, still as super-class of Event_scheduler sql/event_queue.h: Event_queue as super-class of Event_scheduler. Trying to separate the two classes sql/event_scheduler.cc: Event_scheduler as child class of Event_queue. Trying to separate both classes. sql/event_scheduler.h: Event_scheduler as child class of Event_queue. Trying to separate both classes. sql/events.cc: Don't allocate on the stack the scheduler but on the heap. The exact way it is done will be changed, that's ok for now. |

This cut No 7 should finish the part of fixing the parsing of the events : - Event_timed is no more used during parsing. Less problems because it has a mutex. Event_parse_data class is used during parsing. It is suited only for this purpose. It's pretty lightweight - Late checking of data from parsing is being performed. This should solve the problems of nested events in SP or other events (for the situation of no nested bodies). Before if an ALTER EVENT was in a SP, then when the SP was compiled, and not executed, the actual init_xxx methods of Event_timed were called, which is wrong. - It could be a side effect of using a specialized class, but test events_stress is now 25% quicker. Cut No8 will start splitting Event_scheduler into 2 parts, the QUEUE will be moved to Event_queue. mysql-test/r/events.result: update result mysql-test/t/events.test: disabled is actually wrong, should be disable, but because of the early checking it was never parsed. sql/event_data_objects.cc: move add init_xxx methods from Event_timed to Event_parse_data Event_parse data does not need definer_user and definer_host in Event_timed::compile() do not use lex.et, well there is no more lex.et :) sql/event_data_objects.h: move parsing responsibilities from Event_timed to Event_parse_data sql/event_db_repository.cc: No more Event_timed comes from parsing but Event_parse_data The initialization of Item*-s from parsing is done late, and not during the actual parsing. This is the right way to go because if an ALTER EVENT is inside a SP or CREATE EVENT it should not be executed (initialized) during parsing, as it was done. sql/event_db_repository.h: No more Event_timed comes from parsing but Event_parse_data The initialization of Item*-s from parsing is done late, and not during the actual parsing. This is the right way to go because if an ALTER EVENT is inside a SP or CREATE EVENT it should not be executed (initialized) during parsing, as it was done. sql/event_scheduler.cc: No more Event_timed comes from parsing but Event_parse_data The initialization of Item*-s from parsing is done late, and not during the actual parsing.

Cut number 6. Move code from sql_show.cc to event_db_repository.cc that more belongs to the latter. sql/event_db_repository.cc: move code that works with mysql.event from sql_show.cc to event_db_repository.cc . Route through Event_db_repository's interface which is proxied by class Events. The code relies on a function from sql_show.cc which does the actual storage in the schema table. I think it's better to leave the function there because the structure of I_S.EVENTS is defined in sql_show.cc sql/event_db_repository.h: I_S / SHOW EVENTS handling hooks sql/event_scheduler.cc: use the pointer to db_repository which Event_scheduler already has sql/events.cc: Put a comment to get_instance sql/events.h: callback for I_S (sql_show.cc) sql/sql_show.cc: move code that belongs more to Event_db_repository than to here. Use a callback of class Events. Only 1 function is left here, because it copies data into the actual rows of I_S.EVENTS and belongs to this file. sql/sql_show.h: export this function will be called from event_db_repository.cc |
