Bug#17204 "second CALL to procedure crashes Server" Bug#18282 "INFORMATION_SCHEMA.TABLES provides inconsistent info about invalid views" This bug caused crashes or resulted in wrong data being returned when one tried to obtain information from I_S tables about views using stored functions. It was caused by the fact that we were using LEX representing statement which were doing select from I_S tables as active LEX when contents of I_S table were built. So state of this LEX both affected and was affected by open_tables() calls which happened during this process. This resulted in wrong behavior and in violations of some of invariants which caused crashes. This fix tries to solve this problem by properly saving/resetting and restoring part of LEX which affects and is affected by the process of opening tables and views in get_all_tables() routine. To simplify things we separated this part of LEX in a new class and made LEX its descendant. mysql-test/r/information_schema_db.result: test case mysql-test/t/information_schema_db.test: test case sql/sql_lex.cc: To simplify saving/resetting and restoring part of LEX which affects and is affected by the process of opening tables and views we moved it to new class Query_tables_list and made LEX descendant of this class. Also introduced two LEX methods which can be used to save and reset or to restore this state. sql/sql_lex.h: To simplify saving/resetting and restoring part of LEX which affects and is affected by the process of opening tables and views we moved it to new class Query_tables_list and made LEX descendant of this class. Also introduced two LEX methods which can be used to save and reset or to restore this state. sql/sql_show.cc: Now in get_all_tables() routine we properly save/reset and restore part of LEX (statement table list and information about routines used) which affects and is affected by the process of opening tables and views. sql/sql_table.cc: Now we clean-up LEX after opening table (view) in two stages. In the first stage we call LEX::cleanup_after_one_table_open() to clean-up selects lists and derived tables state. In the second stage which happens after close_thread_tables() is invoked we call Query_tables_list::reset_query_tables_list(FALSE) to rollback changes in Query_tables_list.

fix for bug#16642 (Events: No INFORMATION_SCHEMA.EVENTS table) post-review change - use pointer instead of copy on the stack. WL#1034 (Internal CRON) This patch adds INFORMATION_SCHEMA.EVENTS table with the following format: EVENT_CATALOG - MYSQL_TYPE_STRING (Always NULL) EVENT_SCHEMA - MYSQL_TYPE_STRING (the database) EVENT_NAME - MYSQL_TYPE_STRING (the name) DEFINER - MYSQL_TYPE_STRING (user@host) EVENT_BODY - MYSQL_TYPE_STRING (the body from mysql.event) EVENT_TYPE - MYSQL_TYPE_STRING ("ONE TIME" | "RECURRING") EXECUTE_AT - MYSQL_TYPE_TIMESTAMP (set for "ONE TIME" otherwise NULL) INTERVAL_VALUE - MYSQL_TYPE_LONG (set for RECURRING otherwise NULL) INTERVAL_FIELD - MYSQL_TYPE_STRING (set for RECURRING otherwise NULL) SQL_MODE - MYSQL_TYPE_STRING (for now NULL) STARTS - MYSQL_TYPE_TIMESTAMP (starts from mysql.event) ENDS - MYSQL_TYPE_TIMESTAMP (ends from mysql.event) STATUS - MYSQL_TYPE_STRING (ENABLED | DISABLED) ON_COMPLETION - MYSQL_TYPE_STRING (NOT PRESERVE | PRESERVE) CREATED - MYSQL_TYPE_TIMESTAMP LAST_ALTERED - MYSQL_TYPE_TIMESTAMP LAST_EXECUTED - MYSQL_TYPE_TIMESTAMP EVENT_COMMENT - MYSQL_TYPE_STRING SQL_MODE is NULL for now, because the value is still not stored in mysql.event . Support will be added as a fix for another bug. This patch also adds SHOW [FULL] EVENTS [FROM db] [LIKE pattern] 1. SHOW EVENTS shows always only the events on the same user, because the PK of mysql.event is (definer, db, name) several users may have event with the same name -> no information disclosure. 2. SHOW FULL EVENTS - shows the events (in the current db as SHOW EVENTS) of all users. The user has to have PROCESS privilege, if not then SHOW FULL EVENTS behave like SHOW EVENTS. 3. If [FROM db] is specified then this db is considered. 4. Event names can be filtered with LIKE pattern. SHOW EVENTS returns table with the following columns, which are subset of the data which is returned by SELECT * FROM I_S.EVENTS Db Name Definer Type Execute at Interval value Interval field Starts Ends Status mysql-test/lib/init_db.sql: change the PK - (definer, db, name) quicker searches when SHOW EVENTS; allow also different users to have events with the same name -> no information disclosure mysql-test/r/events.result: result of new tests mysql-test/r/information_schema.result: result of new tests mysql-test/r/information_schema_db.result: result of new tests mysql-test/r/system_mysql_db.result: result of new tests mysql-test/t/events.test: new tests for information_schema.events scripts/mysql_create_system_tables.sh: change the PK of mysql.event to (definer, db, name) scripts/mysql_fix_privilege_tables.sql: change the PK of mysql.event to (definer, db, name) sql/event.cc: pass around the definer of the event because of the new PK which is (definer, db, name). It's needed for index searching. sql/event.h: - make enum evex_table_field again public so it can be used in sql_show.cc - make created and modified ulonglong, because they should be such - make public evex_open_event_table so it can be used in sql_show.cc sql/event_executor.cc: - cosmetics sql/event_priv.h: - moved enum evex_table_field and evex_open_event_table() to event.h (made them therefore public) sql/event_timed.cc: - in event_timed::init_definer() always fill this.definer with the concatenated value of definer_user@definer_host. Makes later the work easier. - pass around the definer wherever is needed for searching (new prototype of evex_db_find_evex_aux) sql/mysqld.cc: - add counter for SHOW EVENTS sql/sql_lex.h: - register SHOW EVENTS as command sql/sql_parse.cc: - handle SCH_EVENTS (I_S.EVENTS like SCH_TRIGGERS) - make additional check in case of SHOW EVENTS (check for EVENT on the current database. if it is null check_access() gives appropriate message back. sql/sql_show.cc: - add INFORMATION_SCHEMA.EVENTS and SHOW EVENTS - I_S.EVENTS.SQL_MODE is NULL for now -> not implemented. Trudy asked to be added so bug #16642 can be completely closed. There is another bug report which will fix the lack of storage of SQL_MODE during event creation. sql/sql_yacc.yy: - always call event_timed::init_definer() when CREATE/ALTER/DROP EVENT but not when just compiling the body of the event because in this case this operation is not needed, it takes memory and CPU time and at the end the result is not used. event_timed::definer is used only on SQLCOM_CREATE/ALTER/DROP_EVENT execution not on statement compilation. - add SHOW [FULL] EVENTS [FROM db] [LIKE pattern] in case of FULL and the user has PROCESS privilege then he will see also others' events in the current database, otherwise the output is the same as of SHOW EVENTS. Because the events are per DB only the events from the current database are shown. pattern is applied against event name. FROM db is self explanatory. sql/table.h: add SCH_EVENTS as part of INFORMATION_SCHEMA

In the second stage which happens after close_thread_tables() is invoked we call Query_tables_list::reset_query_tables_list(FALSE) to rollback changes in Query_tables_list.

Bug#17204 "second CALL to procedure crashes Server" Bug#18282 "INFORMATION_SCHEMA.TABLES provides inconsistent info about invalid views" This bug caused crashes or resulted in wrong data being returned when one tried to obtain information from I_S tables about views using stored functions. It was caused by the fact that we were using LEX representing statement which were doing select from I_S tables as active LEX when contents of I_S table were built. So state of this LEX both affected and was affected by open_tables() calls which happened during this process. This resulted in wrong behavior and in violations of some of invariants which caused crashes. This fix tries to solve this problem by properly saving/resetting and restoring part of LEX which affects and is affected by the process of opening tables and views in get_all_tables() routine. To simplify things we separated this part of LEX in a new class and made LEX its descendant. mysql-test/r/information_schema_db.result: test case mysql-test/t/information_schema_db.test: test case sql/sql_lex.cc: To simplify saving/resetting and restoring part of LEX which affects and is affected by the process of opening tables and views we moved it to new class Query_tables_list and made LEX descendant of this class.
