unknown	3eff7d4dd5	Bug#25411 (trigger code truncated), PART I The issue found with bug 25411 is due to the function skip_rear_comments() which damages the source code while implementing a work around. The root cause of the problem is in the lexical analyser, which does not process special comments properly. For special comments like : [1] aaa /!50000 bbb / ccc since 5.0 is a version older that the current code, the parser is in lining the content of the special comment, so that the query to process is [2] aaa bbb ccc However, the text of the query captured when processing a stored procedure, stored function or trigger (or event in 5.1), can be after rebuilding it: [3] aaa bbb / ccc which is wrong. To fix bug 25411 properly, the lexical analyser needs to return [2] when in lining special comments. In order to implement this, some preliminary cleanup is required in the code, which is implemented by this patch. Before this change, the structure named LEX (or st_lex) contains attributes that belong to lexical analysis, as well as attributes that represents the abstract syntax tree (AST) of a statement. Creating a new LEX structure for each statements (which makes sense for the AST part) also re-initialized the lexical analysis phase each time, which is conceptually wrong. With this patch, the previous st_lex structure has been split in two: - st_lex represents the Abstract Syntax Tree for a statement. The name "lex" has not been changed to avoid a bigger impact in the code base. - class lex_input_stream represents the internal state of the lexical analyser, which by definition should not* be reinitialized when parsing multiple statements from the same input stream. This change is a pre-requisite for bug 25411, since the implementation of lex_input_stream will later improve to deal properly with special comments, and this processing can not be done with the current implementation of sp_head::reset_lex and sp_head::restore_lex, which interfere with the lexer. This change set alone does not fix bug 25411. sql/item_func.cc: Refactoring, separate lex_input_stream from st_lex. sql/log_event.cc: Refactoring, separate lex_input_stream from st_lex. sql/mysql_priv.h: Refactoring, separate lex_input_stream from st_lex. sql/slave.cc: Refactoring, separate lex_input_stream from st_lex. sql/sp.cc: Refactoring, separate lex_input_stream from st_lex. sql/sp_head.cc: Refactoring, separate lex_input_stream from st_lex. sql/sp_head.h: Refactoring, separate lex_input_stream from st_lex. sql/sql_class.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_class.h: Refactoring, separate lex_input_stream from st_lex. sql/sql_lex.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_lex.h: Refactoring, separate lex_input_stream from st_lex. sql/sql_parse.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_prepare.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_trigger.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_view.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_yacc.yy: Refactoring, separate lex_input_stream from st_lex.	19 years ago

unknown	fa1d637e89	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.	19 years ago

unknown	7e08016a91	Fix for BUG#27337: Privileges are not properly restored. The problem was that THD::db_access variable was not restored after database switch in stored-routine-execution code. The fix is to restore THD::db_access in this case. Unfortunately, this fix requires additional changes, because in prepare_schema_table(), called on the parsing stage, we checked privileges. That was wrong according to our design, but this flaw haven't struck so far, because it was masked. All privilege checkings must be done on the execution stage in order to be compatible with prepared statements and stored routines. So, this patch also contains patch for prepare_schema_table(), which moves the checkings to the execution phase. mysql-test/r/grant.result: Updated result file. mysql-test/t/grant.test: Added test case for BUG#27337. sql/mysql_priv.h: Added function declaration. sql/sql_db.cc: Fix for BUG#27337 -- set THD::db_access even if we're called from stored-routine-execution code. sql/sql_parse.cc: Split prepare_schema_table() into two functions: - prepare_schema_table(), which is called from the parser (parsing stage); - check_show_access(), which is called on the execution stage. sql/sql_show.cc: Ignore schema_select_lex member if its table is NULL.	19 years ago

unknown	4a76ac5fa6	Bug #27395 OPTION_STATUS_NO_TRANS_UPDATE is not preserved at the end of SF() thd->options' OPTION_STATUS_NO_TRANS_UPDATE bit was not restored at the end of SF() invocation, where SF() modified non-ta table. As the result of this artifact it was not possible to detect whether there were any side-effects when top-level query ends. If the top level query table was not modified and the bit is lost there would be no binlogging. Fixed with preserving the bit inside of thd->no_trans_update struct.

unknown	62b41b5fbc	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.

unknown	cdd2a2e40d	Fix for bug #25966 "2MB per second endless memory consumption after LOCK TABLE ... WRITE". Memory and CPU hogging occured when connection which had to wait for table lock was serviced by thread which previously serviced connection that was killed (note that connections can reuse threads if thread cache is enabled). One possible scenario which exposed this problem was when thread which provided binlog dump to replication slave was implicitly/automatically killed when the same slave reconnected and started pulling data through different thread/connection. The problem also occured when one killed particular query in connection (using KILL QUERY) and later this connection had to wait for some table lock. This problem was caused by the fact that thread-specific mysys_var::abort variable, which indicates that waiting operations on mysys layer should be aborted (this includes waiting for table locks), was set by kill operation but was never reset back. So this value was "inherited" by the following statements or even other connections (which reused the same physical thread). Such discrepancy between this variable and THD::killed flag broke logic on SQL-layer and caused CPU and memory hogging. This patch tries to fix this problem by properly resetting this member. There is no test-case associated with this patch since it is hard to test for memory/CPU hogging conditions in our test-suite. sql/mysqld.cc: We should not forget to reset THD::mysys_var::abort after kill operation if we are going to use thread to which this operation was applied for handling of other connections. sql/sp_head.cc: We should not forget to reset THD::mysys_var::abort after kill operation if we are going to use thread to which this operation was applied for handling of further statements. sql/sql_parse.cc: We should not forget to reset THD::mysys_var::abort after kill operation if we are going to use thread to which this operation was applied for handling of further statements.	19 years ago

unknown	969b71653d	BUG#26881 - Large MERGE tables report incorrect specification when no differences in tables Certain merge tables were wrongly reported as having incorrect definition: - Some fields that are 1 byte long (e.g. TINYINT, CHAR(1)), might be internally casted (in certain cases) to a different type on a storage engine layer. (affects 4.1 and up) - If tables in a merge (and a MERGE table itself) had short VARCHAR column (less than 4 bytes) and at least one (but not all) tables were ALTER'ed (even to an identical table: ALTER TABLE xxx ENGINE=yyy), table definitions went ouf of sync. (affects 4.1 only) This is fixed by relaxing a check for underlying conformance and setting field type to FIELD_TYPE_STRING in case varchar is shorter than 4 when a table is created. myisam/mi_create.c: Added a comment. mysql-test/r/merge.result: A test case for bug#26881. mysql-test/t/merge.test: A test case for bug#26881. sql/ha_myisam.cc: Relaxed some checks performed by check_definition(): As comparing of fulltext keys (and key segments) is not yet implemented, only return an error in case one of keys is fulltext and other is not. Otherwise, if both keys are fulltext, accept them as is. As comparing of spatial keys (and key segments) is not yet implemented, only return an error in case one of keys is spatial and other is not. Otherwise, if both keys are spatial, accept them as is. A workaround to handle situation when field is casted from FIELD_SKIP_ZERO to FIELD_NORMAL. This could happen only in case field length is 1 and row format is fixed. sql/sql_parse.cc: When a table that has varchar field shorter than 4 is created, field type is set to FIELD_TYPE_VAR_STRING. Later, when a table is modified using alter table, field type is changed to FIELD_TYPE_STRING (see Field_string::type). That means HA_OPTION_PACK_RECORD flag might be lost and thus null_bit might be shifted by alter table, in other words alter table doesn't create 100% equal table definition. This is usually not a problem, since when a table is created/altered, definition on a storage engine layer is based on one that is passed from sql layer. But it is a problem for merge engine - null_bit is shifted when a table (merge or underlying) is altered. Set field type to FIELD_TYPE_STRING in case FIELD_TYPE_VAR_STRING is shorter than 4 when a table is created as it is done in Field::type.	19 years ago

unknown	0ea47f3ed4	BUG#9953: CONVERT_TZ requires mysql.time_zone_name to be locked The problem was that some facilities (like CONVERT_TZ() function or server HELP statement) may require implicit access to some tables in 'mysql' database. This access was done by ordinary means of adding such tables to the list of tables the query is going to open. However, if we issued LOCK TABLES before that, we would get "table was not locked" error trying to open such implicit tables. The solution is to treat certain tables as MySQL system tables, like we already do for mysql.proc. Such tables may be opened for reading at any moment regardless of any locks in effect. The cost of this is that system table may be locked for writing only together with other system tables, it is disallowed to lock system tables for writing and have any other lock on any other table. After this patch the following tables are treated as MySQL system tables: mysql.help_category mysql.help_keyword mysql.help_relation mysql.help_topic mysql.proc (it already was) mysql.time_zone mysql.time_zone_leap_second mysql.time_zone_name mysql.time_zone_transition mysql.time_zone_transition_type These tables are now opened with open_system_tables_for_read() and closed with close_system_tables(), or one table may be opened with open_system_table_for_update() and closed with close_thread_tables() (the latter is used for mysql.proc table, which is updated as part of normal MySQL server operation). These functions may be used when some tables were opened and locked already. NOTE: online update of time zone tables is not possible during replication, because there's no time zone cache flush neither on LOCK TABLES, nor on FLUSH TABLES, so the master may serve stale time zone data from cache, while on slave updated data will be loaded from the time zone tables. mysql-test/r/help.result: Update result. mysql-test/r/lock.result: Update result. mysql-test/r/sp-error.result: Update result. mysql-test/r/timezone2.result: Add result for bug#9953: CONVERT_TZ requires mysql.time_zone_name to be locked. mysql-test/r/view.result: Update result: use table t3 rather than utilize MySQL system table. mysql-test/t/help.test: Test that we can use HELP even under LOCK TABLES. mysql-test/t/lock.test: Test LOCK TABLE on system tables. mysql-test/t/timezone2.test: Add test case for bug#9953: CONVERT_TZ requires mysql.time_zone_name to be locked. mysql-test/t/view.test: Update test: use table t3 rather that utilize MySQL system table. sql/handler.h: Fix comment for 'count' parameter of check_if_locking_is_allowed().

unknown	053c6c01d6	A fix for Bug#26750 "valgrind leak in sp_head" (and post-review fixes). The legend: on a replication slave, in case a trigger creation was filtered out because of application of replicate-do-table/ replicate-ignore-table rule, the parsed definition of a trigger was not cleaned up properly. LEX::sphead member was left around and leaked memory. Until the actual implementation of support of replicate-ignore-table rules for triggers by the patch for Bug 24478 it was never the case that "case SQLCOM_CREATE_TRIGGER" was not executed once a trigger was parsed, so the deletion of lex->sphead there worked and the memory did not leak. The fix: The real cause of the bug is that there is no 1 or 2 places where we can clean up the main LEX after parse. And the reason we can not have just one or two places where we clean up the LEX is asymmetric behaviour of MYSQLparse in case of success or error. One of the root causes of this behaviour is the code in Item::Item() constructor. There, a newly created item adds itself to THD::free_list - a single-linked list of Items used in a statement. Yuck. This code is unaware that we may have more than one statement active at a time, and always assumes that the free_list of the current statement is located in THD::free_list. One day we need to be able to explicitly allocate an item in a given Query_arena. Thus, when parsing a definition of a stored procedure, like CREATE PROCEDURE p1() BEGIN SELECT a FROM t1; SELECT b FROM t1; END; we actually need to reset THD::mem_root, THD::free_list and THD::lex to parse the nested procedure statement (SELECT *). The actual reset and restore is implemented in semantic actions attached to sp_proc_stmt grammar rule. The problem is that in case of a parsing error inside a nested statement Bison generated parser would abort immediately, without executing the restore part of the semantic action. This would leave THD in an in-the-middle-of-parsing state. This is why we couldn't have had a single place where we clean up the LEX after MYSQLparse - in case of an error we needed to do a clean up immediately, in case of success a clean up could have been delayed. This left the door open for a memory leak. One of the following possibilities were considered when working on a fix: - patch the replication logic to do the clean up. Rejected as breaks module borders, replication code should not need to know the gory details of clean up procedure after CREATE TRIGGER. - wrap MYSQLparse with a function that would do a clean up. Rejected as ideally we should fix the problem when it happens, not adjust for it outside of the problematic code. - make sure MYSQLparse cleans up after itself by invoking the clean up functionality in the appropriate places before return. Implemented in this patch. - use %destructor rule for sp_proc_stmt to restore THD - cleaner than the prevoius approach, but rejected because needs a careful analysis of the side effects, and this patch is for 5.0, and long term we need to use the next alternative anyway - make sure that sp_proc_stmt doesn't juggle with THD - this is a large work that will affect many modules. Cleanup: move main_lex and main_mem_root from Statement to its only two descendants Prepared_statement and THD. This ensures that when a Statement instance was created for purposes of statement backup, we do not involve LEX constructor/destructor, which is fairly expensive. In order to track that the transformation produces equivalent functionality please check the respective constructors and destructors of Statement, Prepared_statement and THD - these members were used only there. This cleanup is unrelated to the patch. sql/log_event.cc: THD::main_lex is private and should not be used. sql/mysqld.cc: Move MYSQLerror to sql_yacc.yy as it depends on LEX headers now. sql/sql_class.cc: Cleanup: move main_lex and main_mem_root to THD and Prepared_statement sql/sql_class.h: Cleanup: move main_lex and main_mem_root to THD and Prepared_statement sql/sql_lex.cc: Implement st_lex::restore_lex() sql/sql_lex.h: Declare st_lex::restore_lex(). sql/sql_parse.cc: Consolidate the calls to unit.cleanup() and deletion of lex->sphead in mysql_parse (COM_QUERY handler) sql/sql_prepare.cc: No need to delete lex->sphead to restore memory roots now in case of a parse error - this is done automatically inside MYSQLparse sql/sql_trigger.cc: This code could lead to double deletion apparently, as in case of an error lex.sphead was never reset. sql/sql_yacc.yy: Trap all returns from the parser to ensure that MySQL-specific cleanup is invoked: we need to restore the global state of THD and LEX in case of a parsing error. In case of a parsing success this happens as part of normal grammar reduction process.	19 years ago
unknown	79542930ea	WL#3527: Extend IGNORE INDEX so places where index is ignored can be specified Currently MySQL allows one to specify what indexes to ignore during join optimization. The scope of the current USE/FORCE/IGNORE INDEX statement is only the FROM clause, while all other clauses are not affected. However, in certain cases, the optimizer may incorrectly choose an index for sorting and/or grouping, and produce an inefficient query plan. This task provides the means to specify what indexes are ignored/used for what operation in a more fine-grained manner, thus making it possible to manually force a better plan. We do this by extending the current IGNORE/USE/FORCE INDEX syntax to: IGNORE/USE/FORCE INDEX [FOR {JOIN \| ORDER \| GROUP BY}] so that: - if no FOR is specified, the index hint will apply everywhere. - if MySQL is started with the compatibility option --old_mode then an index hint without a FOR clause works as in 5.0 (i.e, the index will only be ignored for JOINs, but can still be used to compute ORDER BY).

unknown	fbc16a85c2	BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join Two problems here: Problem 1: While constructing the join columns list the optimizer does as follows: 1. Sets the join_using_fields/natural_join members of the right JOIN operand. 2. Makes a "table reference" (TABLE_LIST) to parent the two tables. 3. Assigns the join_using_fields/is_natural_join of the wrapper table using join_using_fields/natural_join of the rightmost table 4. Sets join_using_fields to NULL for the right JOIN operand. 5. Passes the parent table up to the same procedure on the upper level. Step 1 overrides the the join_using_fields that are set for a nested join wrapping table in step 4. Fixed by making a designated variable SELECT_LEX::prev_join_using to pass the data from step 1 to step 4 without destroying the wrapping table data. Problem 2: The optimizer checks for ambiguous columns while transforming NATURAL JOIN/JOIN USING to JOIN ON. While doing that there was no distinction between columns that are used in the generated join condition (where ambiguity can be checked) and the other columns (where ambiguity can be checked only when resolving references coming from outside the JOIN construct itself). Fixed by allowing the non-USING columns to be present in multiple copies in both sides of the join and moving the ambiguity check to the place where unqualified references to the join columns are resolved (find_field_in_natural_join()). mysql-test/r/join_nested.result: BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join - test case mysql-test/t/join_nested.test: BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join - test case sql/mysql_priv.h: BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join - use SELECT_LEX to store the ref to JOIN USING list needed by the parser sql/sql_base.cc: BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join - proper check for duplicate cols - more detailed debug output sql/sql_lex.h: BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join - use SELECT_LEX to store the ref to JOIN USING list needed by the parser sql/sql_parse.cc: BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join - proper check for duplicate cols in JOIN USING sql/sql_yacc.yy: BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join - use SELECT_LEX to store the ref to JOIN USING list needed by the parser sql/table.cc: BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join - return null if no table ref (as in nested join columns).	19 years ago

unknown	3c39b0d831	Fix for bug#22740 Events: Decouple Event_queue from Event_db_repository This patch implements the idea of the bug report by making Event_queue unaware of Event_db_repository by making a higher level class - Events, which is aware of most of all classes, responsible for passing all data needed for adding/updating/deleting an event to/from the queue. Introduces few new classes : - Event_worker_thread - Event_queue_element_for_exec sql/event_data_objects.cc: Introduced a new class Event_queue_element_for_exec According to Konstantin it should be named Event_name and hold only two LEX_STRINGs but `dropped` is not saved on disk and will require additional logic in Event_worker_thread class, after loading to compute whether the event should be dropped or not. It's easier just to pass this flag around. Removed Event_queue_element::drop(). This method was a source of a race condition. At the place where the event should be dropped we call Events::drop_event() which is the only code-flow for dropping. In addition, because ::drop_event() holds Events::LOCK_metadata there is no source of race conditions. Before this patch dropping from ::drop() wasn't under LOCK_metadata and races were possible. Because Events::open_event_table was removed as a method, provisionally events_event_db_repository was exported from events.cc till a solution is build where Event_queue_element does not access directly mysql.event. sql/event_data_objects.h: New class Event_queue_element_for_exec added which is returned from Event_queue::get_top_if_time() and passed through Event_scheduler to Event_worker_thread. There by using the (db)name Event_job_data is instanciated and executed. Dropped Event_queue_element::drop() thd was moved out of Event_job_data as it is now part of Event_queue_element_for_exec sql/event_queue.cc: Removed dependency of Event_queue on Event_db_repository. The instantiation of Event_job_data was moved to class Event_worker_thread In place is a return of an object of Event_queue_element_for_exec is used later for instantiating Event_job_data. The `dropped` flag of Event_queue_element is passed over Event_queue_element_for_exec to the code in Event_worker_thread. sql/event_queue.h: Removed dependency of Event_queue on Event_db_repository Removed dependency on Event_scheduler sql/event_scheduler.cc: Added class Event_worker_thread, which is used during the execution of an event. It has a static init() method to get a pointer to Event_db_repository to be used for instantiation of Event_job_data object. This object it then executed. sql/event_scheduler.h: Added class Event_worker_thread, which is used during the execution of an event. sql/events.cc: Removed Events::open_event_table() because it was a product of a bad architecture. sql/events.h: Removed friend definition, unneeded. Fixed Events::drop_event() to have the previous signature without bool only_from_disk sql/sql_parse.cc: Fix call	19 years ago
