WL#3337 (Event scheduler new architecture) 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(). Shortened a bit the runtime for executing events test cases. mysql-test/r/events.result: update results mysql-test/r/events_bugs.result: update results mysql-test/r/events_logs_tests.result: update results mysql-test/r/events_scheduling.result: update results mysql-test/t/events.test: update test make --sleep more appropriate . saving some time could mean failure on loaded boxes though :( add tests for previously uncovered branches. mysql-test/t/events_bugs.test: update test make --sleep more appropriate . saving some time could mean failure on loaded boxes though :( add tests for previously uncovered branches. mysql-test/t/events_logs_tests.test: make the test shorter by time mysql-test/t/events_scheduling.test: when selecting always use ORDER BY mysql-test/t/events_stress.test: sleep 2.5secs for shorter stress test sql/event_data_objects.cc: Event_timed is no more used during execution. Event_timed is no more used during in the memory queue. Event_timed is only used for SHOW CREATE EVENT/ I_S.EVENTS/ SHOW EVENTS Event_basic is the parent of almost all Event data objects. Event_basic -> Event_queue_element (used for the memory queue) -> Event_timed Event_basic -> Event_job_data (the object used for execution) Sql_alloc -> Event_parse_data (used during parsing) sql/event_data_objects.h: Event_timed is no more used during execution. Event_timed is no more used during in the memory queue. Event_timed is only used for SHOW CREATE EVENT/ I_S.EVENTS/ SHOW EVENTS Event_basic is the parent of almost all Event data objects. Event_basic -> Event_queue_element (used for the memory queue) -> Event_timed Event_basic -> Event_job_data (the object used for execution) Sql_alloc -> Event_parse_data (used during parsing) sql/event_db_repository.cc: Cosmetics. load_named_event now uses Event_basic, for polymorphism find_event uses Event_basic, to be polymorphic. use Field **fields= table->field and then index fields[...] Add documentation. Fix documentation. sql/event_db_repository.h: Event_db_repository depends only on Event_basic's interface sql/event_queue.cc: Cosmetics. Don't use Event_timed for the queue and giving back object for execution. Event_queue_element is for the queue, Event_job_data is for execution. Add Event_queue::dump_internal_status() for SHOW SCHEDULER STATUS command sql/event_queue.h: Cosmetics. Don't use Event_timed for the queue and giving back object for execution. Event_queue_element is for the queue, Event_job_data is for execution. Add Event_queue::dump_internal_status() for SHOW SCHEDULER STATUS command sql/event_scheduler_ng.cc: Add back Event_scheduler::cond_wait() Add back Event_scheduler::dump_internal_status() Using Event_job_data for execution. Make the scheduler thread unkillable (thd->command= COM_DAEMON). Add a lot of documentation. sql/event_scheduler_ng.h: Add back Event_scheduler::cond_wait() Add back Event_scheduler::dump_internal_status() Using Event_job_data for execution. sql/events.cc: Documentation Add LOCK_event_metadata sql/events.h: Change the signature of Events::drop_event() not to use sp_name but LEX_STRING sql/share/errmsg.txt: Fix error message sql/sql_parse.cc: Events::drop_event() has new signature

WL#3337 (Events new architecture) 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).

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.

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 mysql-test/t/events_time_zone.test: BitKeeper file /home/tomash/src/mysql_ab/mysql-5.1-wl3698/mysql-test/t/events_time_zone.test

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 mysql-test/t/events_time_zone.test: BitKeeper file /home/tomash/src/mysql_ab/mysql-5.1-wl3698/mysql-test/t/events_time_zone.test

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; client/mysqldump.c: Set original character set and collation before dumping definition query. include/my_sys.h: Move out-parameter to the end of list. mysql-test/lib/mtr_report.pl: Ignore server-warnings during the test case. mysql-test/r/create.result: Update result file. mysql-test/r/ctype_cp932_binlog_stm.result: Update result file. mysql-test/r/events.result: Update result file. mysql-test/r/events_bugs.result: Update result file. mysql-test/r/events_grant.result: Update result file. mysql-test/r/func_in.result: Update result file. mysql-test/r/gis.result: Update result file. mysql-test/r/grant.result: Update result file. mysql-test/r/information_schema.result: Update result file. mysql-test/r/information_schema_db.result: Update result file. mysql-test/r/lowercase_view.result: Update result file. mysql-test/r/mysqldump.result: Update result file. mysql-test/r/ndb_sp.result: Update result file. mysql-test/r/ps.result: Update result file. mysql-test/r/rpl_replicate_do.result: Update result file. mysql-test/r/rpl_sp.result: Update result file. mysql-test/r/rpl_trigger.result: Update result file. mysql-test/r/rpl_view.result: Update result file. mysql-test/r/show_check.result: Update result file. mysql-test/r/skip_grants.result: Update result file. mysql-test/r/sp-destruct.result: Update result file. mysql-test/r/sp-error.result: Update result file. mysql-test/r/sp-security.result: Update result file. mysql-test/r/sp.result: Update result file. mysql-test/r/sql_mode.result: Update result file. mysql-test/r/system_mysql_db.result: Update result file. mysql-test/r/temp_table.result: Update result file. mysql-test/r/trigger-compat.result: Update result file. mysql-test/r/trigger-grant.result: Update result file. mysql-test/r/trigger.result: Update result file. mysql-test/r/view.result: Update result file. mysql-test/r/view_grant.result: Update result file. mysql-test/t/events.test: Update test case (new columns added). mysql-test/t/information_schema.test: Update test case (new columns added). mysql-test/t/show_check.test: Test case for SHOW CREATE TRIGGER in prepared statements and stored routines. mysql-test/t/sp-destruct.test: Update test case (new columns added). mysql-test/t/sp.test: Update test case (new columns added). mysql-test/t/view.test: Update test. mysys/charset.c: Move out-parameter to the end of list. scripts/mysql_system_tables.sql: Add new columns to mysql.proc and mysql.event. scripts/mysql_system_tables_fix.sql: Add new columns to mysql.proc and mysql.event. sql/event_data_objects.cc: Support new attributes for events. sql/event_data_objects.h: Support new attributes for events. sql/event_db_repository.cc: Support new attributes for events. sql/event_db_repository.h: Support new attributes for events. sql/events.cc: Add new columns to SHOW CREATE event resultset. sql/mysql_priv.h: 1.

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.

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.

Used both when an event is created and when it is altered.
WL#3337 (Events new architecture) 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.

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.

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; client/mysqldump.c: Set original character set and collation before dumping definition query. include/my_sys.h: Move out-parameter to the end of list. mysql-test/lib/mtr_report.pl: Ignore server-warnings during the test case. mysql-test/r/create.result: Update result file. mysql-test/r/ctype_cp932_binlog_stm.result: Update result file. mysql-test/r/events.result: Update result file. mysql-test/r/events_bugs.result: Update result file. mysql-test/r/events_grant.result: Update result file. mysql-test/r/func_in.result: Update result file. mysql-test/r/gis.result: Update result file. mysql-test/r/grant.result: Update result file. mysql-test/r/information_schema.result: Update result file. mysql-test/r/information_schema_db.result: Update result file. mysql-test/r/lowercase_view.result: Update result file. mysql-test/r/mysqldump.result: Update result file. mysql-test/r/ndb_sp.result: Update result file. mysql-test/r/ps.result: Update result file. mysql-test/r/rpl_replicate_do.result: Update result file. mysql-test/r/rpl_sp.result: Update result file. mysql-test/r/rpl_trigger.result: Update result file. mysql-test/r/rpl_view.result: Update result file. mysql-test/r/show_check.result: Update result file. mysql-test/r/skip_grants.result: Update result file. mysql-test/r/sp-destruct.result: Update result file. mysql-test/r/sp-error.result: Update result file. mysql-test/r/sp-security.result: Update result file. mysql-test/r/sp.result: Update result file. mysql-test/r/sql_mode.result: Update result file. mysql-test/r/system_mysql_db.result: Update result file. mysql-test/r/temp_table.result: Update result file. mysql-test/r/trigger-compat.result: Update result file. mysql-test/r/trigger-grant.result: Update result file. mysql-test/r/trigger.result: Update result file. mysql-test/r/view.result: Update result file. mysql-test/r/view_grant.result: Update result file. mysql-test/t/events.test: Update test case (new columns added). mysql-test/t/information_schema.test: Update test case (new columns added). mysql-test/t/show_check.test: Test case for SHOW CREATE TRIGGER in prepared statements and stored routines. mysql-test/t/sp-destruct.test: Update test case (new columns added). mysql-test/t/sp.test: Update test case (new columns added). mysql-test/t/view.test: Update test. mysys/charset.c: Move out-parameter to the end of list. scripts/mysql_system_tables.sql: Add new columns to mysql.proc and mysql.event. scripts/mysql_system_tables_fix.sql: Add new columns to mysql.proc and mysql.event. sql/event_data_objects.cc: Support new attributes for events. sql/event_data_objects.h: Support new attributes for events. sql/event_db_repository.cc: Support new attributes for events. sql/event_db_repository.h: Support new attributes for events. sql/events.cc: Add new columns to SHOW CREATE event resultset. sql/mysql_priv.h: 1.

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.

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.

WL#3337 (Events new architecture) 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.

WL#3337 (Events new architecture) 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.

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.

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. This patch adds the column 'originator' to 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. mysql-test/t/events_restart_phase1.test: WL#3629 - Replication of Invocation and Invoked Feature This patch adds the 'originator' column to the events_restart_phase1 test. This was necessary to ensure the manual insert into mysql.event table succeeds because the originator column is set to NOT NULL. scripts/mysql_create_system_tables.sh: 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. scripts/mysql_fix_privilege_tables.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. sql/event_data_objects.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. This patch uses the new Event_basic:: enumerated values. sql/event_data_objects.h: WL#3629 - Replication of Invocation and Invoked Features This patch moves the duplicated enumeration values for ENABLED, SLAVESIDE_DISABLED, and DISABLED to the Event_basic class removing them from the other Event_* classes. sql/event_db_repository.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. 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. sql/event_db_repository.h: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to add a new field named 'originator' to the enum_event_table_field and associated structure. sql/event_queue.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. sql/events.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. sql/lex.h: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to add the new SLAVESIDE_DISABLE symbol to the lexical parser. sql/slave.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit the capture of the error on the slave when a UDF from a loadable library is not loaded on the server when replicated from the master. sql/sql_parse.cc: WL#3629 - Replication of Invocation and Invoked Features This patch removes the comment because drop functions commands are replicated. sql/sql_show.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. The code also adds changes the display width of the status column for the schema table for the show events command and also adds the new column 'originator' to the events_field_info structure. sql/sql_udf.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to add the binlogging of the create and drop function events. sql/sql_yacc.yy: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to change the enumeration of the status column for the events in the parser. The code uses the Event_basic:: enumerations allowing the enums to be defined in one place. mysql-test/t/rpl_events.test: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new test for testing replication of events. The test uses include files so that the test can test under both RBR and SBR. mysql-test/r/rpl_events.result: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new result file for testing replication of events. mysql-test/r/rpl_udf.result: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new result file for testing replication of UDFs. mysql-test/t/rpl_udf.test: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new test for testing replication of UDFs. The test uses include files so that the test can test under both RBR and SBR. mysql-test/include/rpl_events.inc: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new include file for testing replication of events.

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 mysql-test/t/events_time_zone.test: BitKeeper file /home/tomash/src/mysql_ab/mysql-5.1-wl3698/mysql-test/t/events_time_zone.test

Remove direct mapping of enum interval_type to mysql.event.interval_field This decoupling allows in further versions of MySQL enum interval_type to be reordered without this affecting any backward compatibility in the events code. This changeset doesn't change any exposed behavior but makes events' code more durable to changes outside of their code base. To the reviewer: There is no regression test included as it is impossible to construct one with the current infrastructure which can test it. To test the code one has create and event, then change the order of enum interval_type in my_time.h, update sql/time.cc, recompile the server and run it with scheduler running. include/my_time.h: Add a reminder to keep enum interval_type and interval_type_to_name in sync sql/event_data_objects.cc: When loading from disk don't use the integer value of mysql.event.interval_field because it could be different of the values of enum interval_type, if the latter is reordered in a later version of MySQL. Loaded from disk is the string value which is then resolved against interval_type_to_name to get the exact enum value we need for Event_queue_element::interval. sql/event_db_repository.cc: Use interval_type_to_name from sql/time.cc during storage thus decoupling the value stored on disk (the enum) from the integer representation in memory. interval_type can be changed and as long as interval_type_to_name is kept in sync correct values will be saved to disk. sql/mysql_priv.h: add proto of find_string_in_array sql/strfunc.cc: Add a function for searching a LEX_STRING in an array of LEX_STRINGs

Bug#28641 CREATE EVENT with '2038.01.18 03:00:00' let server crash. Creating an EVENT to be executed at a time close to the end of the allowed range (2038.01.19 03:14:07 UTC) would cause the server to crash. The expected behavior is to accept all calendar times within the interval and reject all other values without crashing. This patch replaces the function 'sec_to_epoch_TIME' with a Time_zone API call. This function was broken because it invoked the internal function 'sec_to_epoch' without respecting the restrictions on the function parameters (and this caused assertion failure). It also was used as a reverse function to Time_zone_utc::gmt_sec_to_TIME which it isn't. mysql-test/r/events_bugs.result: Added test case mysql-test/t/events_bugs.test: Added test case sql/event_data_objects.cc: Replaced function 'sec_since_epoch_TIME' since it was implemented as a wrapper around 'sec_since_epoch' without taking parameter restrictions into account. The function was used to load information about event execution time from mysql.events table. Further more, the function wasn't the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used by events code to store information about event execution time. sql/event_db_repository.cc: Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead the function sec_since_epoch_TIME was used as a reverse function to the method my_tz_UTC::gmt_sec_to_TIME. sql/event_queue.cc: Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead the function sec_since_epoch_TIME was used as a reverse function to the method my_tz_UTC::gmt_sec_to_TIME. sql/tztime.cc: * Remove function 'sec_since_epoch_TIME' since it was implemented as a wrapper around 'sec_since_epoch' without taking parameter restrictions into account. The function was used to load information about event execution time from mysql.events table. Further more, the function wasn't the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used by events code to store information about event execution time. * Added static Time_zone object for UTC+0 time zone. sql/tztime.h: Include extern pointer to static Time_zone object.

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.

Bug#28641 CREATE EVENT with '2038.01.18 03:00:00' let server crash. Creating an EVENT to be executed at a time close to the end of the allowed range (2038.01.19 03:14:07 UTC) would cause the server to crash. The expected behavior is to accept all calendar times within the interval and reject all other values without crashing. This patch replaces the function 'sec_to_epoch_TIME' with a Time_zone API call. This function was broken because it invoked the internal function 'sec_to_epoch' without respecting the restrictions on the function parameters (and this caused assertion failure). It also was used as a reverse function to Time_zone_utc::gmt_sec_to_TIME which it isn't. mysql-test/r/events_bugs.result: Added test case mysql-test/t/events_bugs.test: Added test case sql/event_data_objects.cc: Replaced function 'sec_since_epoch_TIME' since it was implemented as a wrapper around 'sec_since_epoch' without taking parameter restrictions into account. The function was used to load information about event execution time from mysql.events table. Further more, the function wasn't the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used by events code to store information about event execution time. sql/event_db_repository.cc: Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead the function sec_since_epoch_TIME was used as a reverse function to the method my_tz_UTC::gmt_sec_to_TIME. sql/event_queue.cc: Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead the function sec_since_epoch_TIME was used as a reverse function to the method my_tz_UTC::gmt_sec_to_TIME. sql/tztime.cc: * Remove function 'sec_since_epoch_TIME' since it was implemented as a wrapper around 'sec_since_epoch' without taking parameter restrictions into account. The function was used to load information about event execution time from mysql.events table. Further more, the function wasn't the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used by events code to store information about event execution time. * Added static Time_zone object for UTC+0 time zone. sql/tztime.h: Include extern pointer to static Time_zone object.

Bug#28641 CREATE EVENT with '2038.01.18 03:00:00' let server crash. Creating an EVENT to be executed at a time close to the end of the allowed range (2038.01.19 03:14:07 UTC) would cause the server to crash. The expected behavior is to accept all calendar times within the interval and reject all other values without crashing. This patch replaces the function 'sec_to_epoch_TIME' with a Time_zone API call. This function was broken because it invoked the internal function 'sec_to_epoch' without respecting the restrictions on the function parameters (and this caused assertion failure). It also was used as a reverse function to Time_zone_utc::gmt_sec_to_TIME which it isn't. mysql-test/r/events_bugs.result: Added test case mysql-test/t/events_bugs.test: Added test case sql/event_data_objects.cc: Replaced function 'sec_since_epoch_TIME' since it was implemented as a wrapper around 'sec_since_epoch' without taking parameter restrictions into account. The function was used to load information about event execution time from mysql.events table. Further more, the function wasn't the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used by events code to store information about event execution time. sql/event_db_repository.cc: Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead the function sec_since_epoch_TIME was used as a reverse function to the method my_tz_UTC::gmt_sec_to_TIME. sql/event_queue.cc: Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead the function sec_since_epoch_TIME was used as a reverse function to the method my_tz_UTC::gmt_sec_to_TIME. sql/tztime.cc: * Remove function 'sec_since_epoch_TIME' since it was implemented as a wrapper around 'sec_since_epoch' without taking parameter restrictions into account. The function was used to load information about event execution time from mysql.events table. Further more, the function wasn't the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used by events code to store information about event execution time. * Added static Time_zone object for UTC+0 time zone. sql/tztime.h: Include extern pointer to static Time_zone object.

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.

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; client/mysqldump.c: Set original character set and collation before dumping definition query. include/my_sys.h: Move out-parameter to the end of list. mysql-test/lib/mtr_report.pl: Ignore server-warnings during the test case. mysql-test/r/create.result: Update result file. mysql-test/r/ctype_cp932_binlog_stm.result: Update result file. mysql-test/r/events.result: Update result file. mysql-test/r/events_bugs.result: Update result file. mysql-test/r/events_grant.result: Update result file. mysql-test/r/func_in.result: Update result file. mysql-test/r/gis.result: Update result file. mysql-test/r/grant.result: Update result file. mysql-test/r/information_schema.result: Update result file. mysql-test/r/information_schema_db.result: Update result file. mysql-test/r/lowercase_view.result: Update result file. mysql-test/r/mysqldump.result: Update result file. mysql-test/r/ndb_sp.result: Update result file. mysql-test/r/ps.result: Update result file. mysql-test/r/rpl_replicate_do.result: Update result file. mysql-test/r/rpl_sp.result: Update result file. mysql-test/r/rpl_trigger.result: Update result file. mysql-test/r/rpl_view.result: Update result file. mysql-test/r/show_check.result: Update result file. mysql-test/r/skip_grants.result: Update result file. mysql-test/r/sp-destruct.result: Update result file. mysql-test/r/sp-error.result: Update result file. mysql-test/r/sp-security.result: Update result file. mysql-test/r/sp.result: Update result file. mysql-test/r/sql_mode.result: Update result file. mysql-test/r/system_mysql_db.result: Update result file. mysql-test/r/temp_table.result: Update result file. mysql-test/r/trigger-compat.result: Update result file. mysql-test/r/trigger-grant.result: Update result file. mysql-test/r/trigger.result: Update result file. mysql-test/r/view.result: Update result file. mysql-test/r/view_grant.result: Update result file. mysql-test/t/events.test: Update test case (new columns added). mysql-test/t/information_schema.test: Update test case (new columns added). mysql-test/t/show_check.test: Test case for SHOW CREATE TRIGGER in prepared statements and stored routines. mysql-test/t/sp-destruct.test: Update test case (new columns added). mysql-test/t/sp.test: Update test case (new columns added). mysql-test/t/view.test: Update test. mysys/charset.c: Move out-parameter to the end of list. scripts/mysql_system_tables.sql: Add new columns to mysql.proc and mysql.event. scripts/mysql_system_tables_fix.sql: Add new columns to mysql.proc and mysql.event. sql/event_data_objects.cc: Support new attributes for events. sql/event_data_objects.h: Support new attributes for events. sql/event_db_repository.cc: Support new attributes for events. sql/event_db_repository.h: Support new attributes for events. sql/events.cc: Add new columns to SHOW CREATE event resultset. sql/mysql_priv.h: 1.

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.

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.

WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

WL#3337 (Event scheduler new architecture) 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().

Don't use Event_timed for the queue and giving back object for execution. Event_queue_element is for the queue, Event_job_data is for execution. Add Event_queue::dump_internal_status() for SHOW SCHEDULER STATUS command sql/event_queue.h: Cosmetics. Don't use Event_timed for the queue and giving back object for execution. Event_queue_element is for the queue, Event_job_data is for execution.

Fixed a lot of compiler warnings and errors detected by Forte C++ on Solaris Faster thr_alarm() Added 'Opened_files' status variable to track calls to my_open() Don't give warnings when running mysql_install_db Added option --source-install to mysql_install_db I had to do the following renames() as used polymorphism didn't work with Forte compiler on 64 bit systems index_read() -> index_read_map() index_read_idx() -> index_read_idx_map() index_read_last() -> index_read_last_map() BUILD/compile-solaris-sparc-forte: Updated script to current Solaris installations Now we compile by default for 64 bits client/mysql.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) client/mysql_upgrade.c: Fixed compiler warning (on Forte) client/mysqladmin.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) client/mysqlcheck.c: Fixed compiler warning (on Forte) client/mysqldump.c: Fixed compiler warning (on Forte) client/mysqlslap.c: Fixed compiler warning (on Forte) client/mysqltest.c: Fixed compiler warning (on Forte) client/sql_string.cc: Avoid compiler warnings when using C function pointers in C++ configure.in: Added detection of mtmalloc and ieeefp.h extra/replace.c: Fixed compiler warning (on Forte) include/m_ctype.h: Added some typedef's to make it easy to use C function pointers in C++ include/my_sys.h: Added my_file_total_opened (counter for calls to my_open()) include/myisam.h: Fixed compiler warning (on Forte) libmysql/libmysql.c: Fixed compiler warning (on Forte) by adding casts and change types libmysql/manager.c: Fixed compiler warning (on Forte) by adding casts and change types mysql-test/r/ctype_cp932_binlog_stm.result: Updated positions (Needed because we didn't before correctly restore collation_database after running stored procedure mysys/my_fopen.c: Count number of opened files mysys/my_open.c: Count number of opened files mysys/my_static.c: Count number of opened files mysys/thr_alarm.c: Optimization to do less alarm() and pthread_sigmask() calls. Idea is to remember time for next pending alarm and not reschedule a new alarm if it's after the current one. Before we only did this if there was other pending alarms. We don't have to use pthread_sigmask() in case of 'USE_ONE_SIGNAL_HAND' as the alarm() signal will be blocked for the calling thread anyway and no other thread will have the alarm() signal enabled to call process_alarm() regex/regcomp.c: Fixed compiler warning (on Forte) by adding casts and change types scripts/mysql_install_db.sh: Added option --source-install to allow one to create a mysql database from the source tree without installing MySQL Don't give (unnecessary) warnings server-tools/instance-manager/angel.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) server-tools/instance-manager/thread_registry.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/event_db_repository.cc: index_read() -> index_read_map() sql/event_queue.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/field.cc: Fixed compiler warnings about hidden fields sql/ha_partition.cc: Fixed compiler warnings about hidden fields index_read() -> index_read_map() sql/ha_partition.h: index_read() -> index_read_map() sql/handler.cc: Added PAGE option to row types (to prepare for future) index_read() -> index_read_map() sql/handler.h: Added ROW_TYPE_PAGE (for future) Added flag to signal if table was to be created transactionally I had to do the following renames() as used polymorphism didn't work with Forte compiler on 64 bit systems index_read() -> index_read_map() index_read_idx() -> index_read_idx_map() index_read_last() -> index_read_last_map() sql/item.cc: Fixed indentation Renamed local variable to avoid hiding class variable sql/item_cmpfunc.cc: Renamed local variable to avoid hiding class variable sql/item_cmpfunc.h: Removed not used variable sql/item_func.cc: Renamed local variable to avoid hiding class variable sql/item_strfunc.cc: Moved functions from Item_strfunc.cc sql/item_strfunc.h: Move functions to item_strfunc.cc Use C function pointer type to avoid compiler warnings (with Forte) sql/item_subselect.cc: index_read() -> index_read_map() sql/item_xmlfunc.cc: Renamed local variable to avoid hiding class variable Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/key.cc: Fixed indentation sql/log.cc: Renamed local variable to avoid hiding class variable sql/log_event.cc: Removed call to my_time() when creating class instance of Log_event() as this may have static instances.

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.

It's assumed that the caller knows what they are doing:
- whether it was necessary to reset-and-backup the open tables state
- whether the requested lock does not lead to a deadlock
- whether this open mode would work under LOCK TABLES, or inside a
stored function or trigger.
Patch for BUG#31111: --read-only crashes MySQL (events fail to load). There actually were several problems here: - WRITE-lock is required to load events from the mysql.event table, but in the read-only mode an ordinary user can not acquire it; - Security_context::master_access attribute was not properly initialized in Security_context::init(), which led to differences in behavior with and without debug configure options. - if the server failed to load events from mysql.event, it forgot to close the mysql.event table, that led to the coredump, described in the bug report. The patch is to fix all these problems: - Use the super-user to acquire WRITE-lock on the mysql.even table; - The WRITE-lock is acquired by the event scheduler in two cases: - on initial loading of events from the database; - when an event has been executed, so its attributes should be updated. Other cases when WRITE-lock is needed for the mysql.event table happen under the user account. So, nothing should be changed there for the read-only mode. The user is able to create/update/drop an event only if he is a super-user. - Initialize Security_context::master_access; - Close the mysql.event table in case something went wrong. mysql-test/r/events_bugs.result: Update result file. mysql-test/t/events_bugs.test: A test case for BUG#31111: --read-only crashes MySQL (events fail to load). sql/event_data_objects.cc: When the worker thread is going to drop event after the execution we should do it under the super-user privileges in order to be able to lock the mysql.event table for writing in the read-only mode. This is a system operation, where user SQL can not be executed. So, there is no risk in compromising security by dropping an event under the super-user privileges. sql/event_db_repository.cc: 1. Close tables if something went wrong in simple_open_n_lock_tables(); 2. As soon as the system event scheduler thread is running under the super-user privileges, we should always be able to acquire WRITE-lock on the mysql.event table. However, let's have an assert to check this. sql/event_scheduler.cc: Run the system event scheduler thread under the super-user privileges. In particular, this is needed to be able to lock the mysql.event table for writing when the server is running in the read-only mode. The event scheduler executes only system operations and does not execute user SQL (this is what the worker threads for). So, there is no risk in compromising security by running the event scheduler under the super-user privileges. sql/events.cc: Open the mysql.event table as the super user to be able to acquire WRITE-lock in the read-only mode. sql/sql_class.cc: Initialize Security_context::master_acces.

Note that if the table can't be locked successfully this operation will
close it. Therefore it provides guarantee that it either opens and locks
table or fails without leaving any tables open.

Patch for BUG#31111: --read-only crashes MySQL (events fail to load). There actually were several problems here: - WRITE-lock is required to load events from the mysql.event table, but in the read-only mode an ordinary user can not acquire it; - Security_context::master_access attribute was not properly initialized in Security_context::init(), which led to differences in behavior with and without debug configure options. - if the server failed to load events from mysql.event, it forgot to close the mysql.event table, that led to the coredump, described in the bug report. The patch is to fix all these problems: - Use the super-user to acquire WRITE-lock on the mysql.even table; - The WRITE-lock is acquired by the event scheduler in two cases: - on initial loading of events from the database; - when an event has been executed, so its attributes should be updated. Other cases when WRITE-lock is needed for the mysql.event table happen under the user account. So, nothing should be changed there for the read-only mode. The user is able to create/update/drop an event only if he is a super-user. - Initialize Security_context::master_access; - Close the mysql.event table in case something went wrong. mysql-test/r/events_bugs.result: Update result file. mysql-test/t/events_bugs.test: A test case for BUG#31111: --read-only crashes MySQL (events fail to load). sql/event_data_objects.cc: When the worker thread is going to drop event after the execution we should do it under the super-user privileges in order to be able to lock the mysql.event table for writing in the read-only mode. This is a system operation, where user SQL can not be executed. So, there is no risk in compromising security by dropping an event under the super-user privileges. sql/event_db_repository.cc: 1. Close tables if something went wrong in simple_open_n_lock_tables(); 2. As soon as the system event scheduler thread is running under the super-user privileges, we should always be able to acquire WRITE-lock on the mysql.event table. However, let's have an assert to check this. sql/event_scheduler.cc: Run the system event scheduler thread under the super-user privileges. In particular, this is needed to be able to lock the mysql.event table for writing when the server is running in the read-only mode. The event scheduler executes only system operations and does not execute user SQL (this is what the worker threads for). So, there is no risk in compromising security by running the event scheduler under the super-user privileges. sql/events.cc: Open the mysql.event table as the super user to be able to acquire WRITE-lock in the read-only mode. sql/sql_class.cc: Initialize Security_context::master_acces.

WL#3337 (Events new architecture) 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.

/**
Creates an event record in mysql.event table.
WL#3337 (Events new architecture) 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.

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/sql_lex.cc: lex->et_compile_phase and lex->et are no more. Use lex->event_parse_data sql/sql_lex.h: lex->et_compile_phase and lex->et are no more. Use lex->event_parse_data sql/sql_parse.cc: lex->et_compile_phase and lex->et are no more. Use lex->event_parse_data ACL checks were moved inside the Events subsystem. Also ending of the transaction is performed only just before doing disk operation. Therefore only when needed. sql/sql_yacc.yy: lex->et and lex->et_parse_phase are no more Use the specialized for parsing Event_parse_data

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.

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

WL#3337 (Events new architecture) 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.

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.

WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

WL#3337 (Events new architecture) 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).

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.

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.

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 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.

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.

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. This patch adds the column 'originator' to 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. mysql-test/t/events_restart_phase1.test: WL#3629 - Replication of Invocation and Invoked Feature This patch adds the 'originator' column to the events_restart_phase1 test. This was necessary to ensure the manual insert into mysql.event table succeeds because the originator column is set to NOT NULL. scripts/mysql_create_system_tables.sh: 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. scripts/mysql_fix_privilege_tables.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. sql/event_data_objects.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. This patch uses the new Event_basic:: enumerated values. sql/event_data_objects.h: WL#3629 - Replication of Invocation and Invoked Features This patch moves the duplicated enumeration values for ENABLED, SLAVESIDE_DISABLED, and DISABLED to the Event_basic class removing them from the other Event_* classes. sql/event_db_repository.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. 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. sql/event_db_repository.h: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to add a new field named 'originator' to the enum_event_table_field and associated structure. sql/event_queue.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. sql/events.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. sql/lex.h: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to add the new SLAVESIDE_DISABLE symbol to the lexical parser. sql/slave.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit the capture of the error on the slave when a UDF from a loadable library is not loaded on the server when replicated from the master. sql/sql_parse.cc: WL#3629 - Replication of Invocation and Invoked Features This patch removes the comment because drop functions commands are replicated. sql/sql_show.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to permit processing of the new enum SLAVESIDE_DISABLED which is set on the slave during replication of events. The code also adds changes the display width of the status column for the schema table for the show events command and also adds the new column 'originator' to the events_field_info structure. sql/sql_udf.cc: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to add the binlogging of the create and drop function events. sql/sql_yacc.yy: WL#3629 - Replication of Invocation and Invoked Features This patch modifies the code to change the enumeration of the status column for the events in the parser. The code uses the Event_basic:: enumerations allowing the enums to be defined in one place. mysql-test/t/rpl_events.test: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new test for testing replication of events. The test uses include files so that the test can test under both RBR and SBR. mysql-test/r/rpl_events.result: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new result file for testing replication of events. mysql-test/r/rpl_udf.result: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new result file for testing replication of UDFs. mysql-test/t/rpl_udf.test: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new test for testing replication of UDFs. The test uses include files so that the test can test under both RBR and SBR. mysql-test/include/rpl_events.inc: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new include file for testing replication of events. This file contains the core test procedures. mysql-test/include/rpl_udf.inc: WL#3629 - Replication of Invocation and Invoked Features This patch adds a new include file for testing replication of UDFs.

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.

Move Event_job_data::compile() next to Event_job_data::execute() sql/event_data_objects.h: Remove unneeded error codes and defines Move function declarations at the end of the header sql/event_db_repository.cc: Fix function documentation. Event_db_repository::update_event() now uses LEX_STRING *-s instead of sp_name . Lower coupling. sql/event_db_repository.h: Event_db_repository::update_event() now uses LEX_STRING *-s instead of sp_name .

WL#3337 (Events new architecture) 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.

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/sql_lex.cc: lex->et_compile_phase and lex->et are no more. Use lex->event_parse_data sql/sql_lex.h: lex->et_compile_phase and lex->et are no more. Use lex->event_parse_data sql/sql_parse.cc: lex->et_compile_phase and lex->et are no more. Use lex->event_parse_data ACL checks were moved inside the Events subsystem. Also ending of the transaction is performed only just before doing disk operation. Therefore only when needed. sql/sql_yacc.yy: lex->et and lex->et_parse_phase are no more Use the specialized for parsing Event_parse_data

WL#3337 (Events new architecture) 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.

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.

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.

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

WL#3337 (Events new architecture) 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.

This should solve the problems of nested events in SP or other events (for the situation of no nested bodies).

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.

Parsing only gives some information about event validity, but far not all. Consolidate the business logic of Events DDL in this module.

WL#3337 (Events new architecture) 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.

Use lex->event_parse_data sql/sql_lex.h: lex->et_compile_phase and lex->et are no more. Use lex->event_parse_data sql/sql_parse.cc: lex->et_compile_phase and lex->et are no more. Use lex->event_parse_data ACL checks were moved inside the Events subsystem. Also ending of the transaction is performed only just before doing disk operation. Therefore only when needed. sql/sql_yacc.yy: lex->et and lex->et_parse_phase are no more Use the specialized for parsing Event_parse_data

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.

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.

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.

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.

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.

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.

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.

WL#3337 (Event scheduler new architecture) 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().

Positions the internal pointer of `table` to the place where (db, name)
is stored.
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.

TABLE *table)
{
WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

DBUG_ENTER("Event_db_repository::find_named_event");
WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

WL#3337 (Event scheduler new architecture) More small fixes to the API : use LEX_STRING instead of LEX_STRING* and if error then return bool(true) instead of error code. Merged functions. Reduced usage of sp_name. Fixed a lot of function documentation errors. Added function documentation wherever needed. Removed some unused defines and error codes. Next to come is batch rename of Event_scheduler_ng to Event_scheduler. mysql-test/r/events.result: update result mysql-test/r/events_logs_tests.result: update result mysql-test/t/events.test: more test coverage mysql-test/t/events_logs_tests.test: fix test sql/event_data_objects.cc: Cosmetics. Fix function documentation whenever needed. Move Event_job_data::compile() next to Event_job_data::execute() sql/event_data_objects.h: Remove unneeded error codes and defines Move function declarations at the end of the header sql/event_db_repository.cc: Fix function documentation. Event_db_repository::update_event() now uses LEX_STRING *-s instead of sp_name . Lower coupling. sql/event_db_repository.h: Event_db_repository::update_event() now uses LEX_STRING *-s instead of sp_name . Lower coupling. find_event -> find_named_event find_event_by_name is not used externally, merge with load_named_event() sql/event_queue.cc: LEX_STRING* to LEX_STRING Fix comments. Fix and add function documentation. Remove Event_queue::events_count() as it is unused Change get_top_for_execution_if_time() to return status code as return value and the object is in out parameter. sql/event_queue.h: LEX_STRING* to LEX_STRING Fix comments. Fix and add function documentation. Remove Event_queue::events_count() as it is unused Change get_top_for_execution_if_time() to return status code as return value and the object is in out parameter. Try to detect also lock attemptions for deadlocks. sql/event_scheduler_ng.cc: Always execute on thd->mem_root Fix according to changed API of Event_queue::get_top_for_execution_if_time() sql/events.cc: Fix function documentation. Fix code after API changes of internal Event module classes. sql/events.h: sp_name -> LEX_STRINGs sql/sql_parse.cc: Fix according to changed API of Events::show_create_event() sql/sql_yacc.yy: Don't pass NULL as third parameter to sp_head::init_strings()

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.

Fixed a lot of compiler warnings and errors detected by Forte C++ on Solaris Faster thr_alarm() Added 'Opened_files' status variable to track calls to my_open() Don't give warnings when running mysql_install_db Added option --source-install to mysql_install_db I had to do the following renames() as used polymorphism didn't work with Forte compiler on 64 bit systems index_read() -> index_read_map() index_read_idx() -> index_read_idx_map() index_read_last() -> index_read_last_map() BUILD/compile-solaris-sparc-forte: Updated script to current Solaris installations Now we compile by default for 64 bits client/mysql.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) client/mysql_upgrade.c: Fixed compiler warning (on Forte) client/mysqladmin.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) client/mysqlcheck.c: Fixed compiler warning (on Forte) client/mysqldump.c: Fixed compiler warning (on Forte) client/mysqlslap.c: Fixed compiler warning (on Forte) client/mysqltest.c: Fixed compiler warning (on Forte) client/sql_string.cc: Avoid compiler warnings when using C function pointers in C++ configure.in: Added detection of mtmalloc and ieeefp.h extra/replace.c: Fixed compiler warning (on Forte) include/m_ctype.h: Added some typedef's to make it easy to use C function pointers in C++ include/my_sys.h: Added my_file_total_opened (counter for calls to my_open()) include/myisam.h: Fixed compiler warning (on Forte) libmysql/libmysql.c: Fixed compiler warning (on Forte) by adding casts and change types libmysql/manager.c: Fixed compiler warning (on Forte) by adding casts and change types mysql-test/r/ctype_cp932_binlog_stm.result: Updated positions (Needed because we didn't before correctly restore collation_database after running stored procedure mysys/my_fopen.c: Count number of opened files mysys/my_open.c: Count number of opened files mysys/my_static.c: Count number of opened files mysys/thr_alarm.c: Optimization to do less alarm() and pthread_sigmask() calls. Idea is to remember time for next pending alarm and not reschedule a new alarm if it's after the current one. Before we only did this if there was other pending alarms. We don't have to use pthread_sigmask() in case of 'USE_ONE_SIGNAL_HAND' as the alarm() signal will be blocked for the calling thread anyway and no other thread will have the alarm() signal enabled to call process_alarm() regex/regcomp.c: Fixed compiler warning (on Forte) by adding casts and change types scripts/mysql_install_db.sh: Added option --source-install to allow one to create a mysql database from the source tree without installing MySQL Don't give (unnecessary) warnings server-tools/instance-manager/angel.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) server-tools/instance-manager/thread_registry.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/event_db_repository.cc: index_read() -> index_read_map() sql/event_queue.cc: Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/field.cc: Fixed compiler warnings about hidden fields sql/ha_partition.cc: Fixed compiler warnings about hidden fields index_read() -> index_read_map() sql/ha_partition.h: index_read() -> index_read_map() sql/handler.cc: Added PAGE option to row types (to prepare for future) index_read() -> index_read_map() sql/handler.h: Added ROW_TYPE_PAGE (for future) Added flag to signal if table was to be created transactionally I had to do the following renames() as used polymorphism didn't work with Forte compiler on 64 bit systems index_read() -> index_read_map() index_read_idx() -> index_read_idx_map() index_read_last() -> index_read_last_map() sql/item.cc: Fixed indentation Renamed local variable to avoid hiding class variable sql/item_cmpfunc.cc: Renamed local variable to avoid hiding class variable sql/item_cmpfunc.h: Removed not used variable sql/item_func.cc: Renamed local variable to avoid hiding class variable sql/item_strfunc.cc: Moved functions from Item_strfunc.cc sql/item_strfunc.h: Move functions to item_strfunc.cc Use C function pointer type to avoid compiler warnings (with Forte) sql/item_subselect.cc: index_read() -> index_read_map() sql/item_xmlfunc.cc: Renamed local variable to avoid hiding class variable Declare functions sent to C code with extern "C" to avoid compiler warnings (on Forte) sql/key.cc: Fixed indentation sql/log.cc: Renamed local variable to avoid hiding class variable sql/log_event.cc: Removed call to my_time() when creating class instance of Log_event() as this may have static instances.

*/
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

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.

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.

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.

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.

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.

WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

WL#3337 (Event scheduler new architecture) 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(). Shortened a bit the runtime for executing events test cases. mysql-test/r/events.result: update results mysql-test/r/events_bugs.result: update results mysql-test/r/events_logs_tests.result: update results mysql-test/r/events_scheduling.result: update results mysql-test/t/events.test: update test make --sleep more appropriate . saving some time could mean failure on loaded boxes though :( add tests for previously uncovered branches. mysql-test/t/events_bugs.test: update test make --sleep more appropriate . saving some time could mean failure on loaded boxes though :( add tests for previously uncovered branches. mysql-test/t/events_logs_tests.test: make the test shorter by time mysql-test/t/events_scheduling.test: when selecting always use ORDER BY mysql-test/t/events_stress.test: sleep 2.5secs for shorter stress test sql/event_data_objects.cc: Event_timed is no more used during execution. Event_timed is no more used during in the memory queue. Event_timed is only used for SHOW CREATE EVENT/ I_S.EVENTS/ SHOW EVENTS Event_basic is the parent of almost all Event data objects. Event_basic -> Event_queue_element (used for the memory queue) -> Event_timed Event_basic -> Event_job_data (the object used for execution) Sql_alloc -> Event_parse_data (used during parsing) sql/event_data_objects.h: Event_timed is no more used during execution.

Don't use Event_timed for the queue and giving back object for execution. Event_queue_element is for the queue, Event_job_data is for execution. Add Event_queue::dump_internal_status() for SHOW SCHEDULER STATUS command sql/event_queue.h: Cosmetics. Don't use Event_timed for the queue and giving back object for execution. Event_queue_element is for the queue, Event_job_data is for execution.

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.

Patch for BUG#31111: --read-only crashes MySQL (events fail to load). There actually were several problems here: - WRITE-lock is required to load events from the mysql.event table, but in the read-only mode an ordinary user can not acquire it; - Security_context::master_access attribute was not properly initialized in Security_context::init(), which led to differences in behavior with and without debug configure options. - if the server failed to load events from mysql.event, it forgot to close the mysql.event table, that led to the coredump, described in the bug report. The patch is to fix all these problems: - Use the super-user to acquire WRITE-lock on the mysql.even table; - The WRITE-lock is acquired by the event scheduler in two cases: - on initial loading of events from the database; - when an event has been executed, so its attributes should be updated. Other cases when WRITE-lock is needed for the mysql.event table happen under the user account. So, nothing should be changed there for the read-only mode. The user is able to create/update/drop an event only if he is a super-user. - Initialize Security_context::master_access; - Close the mysql.event table in case something went wrong. mysql-test/r/events_bugs.result: Update result file. mysql-test/t/events_bugs.test: A test case for BUG#31111: --read-only crashes MySQL (events fail to load). sql/event_data_objects.cc: When the worker thread is going to drop event after the execution we should do it under the super-user privileges in order to be able to lock the mysql.event table for writing in the read-only mode. This is a system operation, where user SQL can not be executed. So, there is no risk in compromising security by dropping an event under the super-user privileges. sql/event_db_repository.cc: 1. Close tables if something went wrong in simple_open_n_lock_tables(); 2. As soon as the system event scheduler thread is running under the super-user privileges, we should always be able to acquire WRITE-lock on the mysql.event table. However, let's have an assert to check this. sql/event_scheduler.cc: Run the system event scheduler thread under the super-user privileges. In particular, this is needed to be able to lock the mysql.event table for writing when the server is running in the read-only mode. The event scheduler executes only system operations and does not execute user SQL (this is what the worker threads for). So, there is no risk in compromising security by running the event scheduler under the super-user privileges. sql/events.cc: Open the mysql.event table as the super user to be able to acquire WRITE-lock in the read-only mode. sql/sql_class.cc: Initialize Security_context::master_acces.

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.

Bug#28641 CREATE EVENT with '2038.01.18 03:00:00' let server crash. Creating an EVENT to be executed at a time close to the end of the allowed range (2038.01.19 03:14:07 UTC) would cause the server to crash. The expected behavior is to accept all calendar times within the interval and reject all other values without crashing. This patch replaces the function 'sec_to_epoch_TIME' with a Time_zone API call. This function was broken because it invoked the internal function 'sec_to_epoch' without respecting the restrictions on the function parameters (and this caused assertion failure). It also was used as a reverse function to Time_zone_utc::gmt_sec_to_TIME which it isn't. mysql-test/r/events_bugs.result: Added test case mysql-test/t/events_bugs.test: Added test case sql/event_data_objects.cc: Replaced function 'sec_since_epoch_TIME' since it was implemented as a wrapper around 'sec_since_epoch' without taking parameter restrictions into account. The function was used to load information about event execution time from mysql.events table. Further more, the function wasn't the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used by events code to store information about event execution time. sql/event_db_repository.cc: Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead the function sec_since_epoch_TIME was used as a reverse function to the method my_tz_UTC::gmt_sec_to_TIME. sql/event_queue.cc: Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead the function sec_since_epoch_TIME was used as a reverse function to the method my_tz_UTC::gmt_sec_to_TIME. sql/tztime.cc: * Remove function 'sec_since_epoch_TIME' since it was implemented as a wrapper around 'sec_since_epoch' without taking parameter restrictions into account. The function was used to load information about event execution time from mysql.events table. Further more, the function wasn't the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used by events code to store information about event execution time. * Added static Time_zone object for UTC+0 time zone. sql/tztime.h: Include extern pointer to static Time_zone object.

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.

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.
