Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function. If the function is declared to modify data and does not complete, warning "broken binlog". Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!" (see comment in code). sql/sp.cc: If binlog is on: errors if one wants to create a non-deterministic update routine (repeatability problem - note that the test is not perfect for functions) or does not have SUPER (because routines can easily be made to destroy slave's data with just CREATE ROUTINE and EXECUTE priv on master). --log-bin-trust-routine-creators removes these errors. Binlogging of CREATE PROCEDURE|FUNCTION. sql/sql_acl.cc: No thd==0 in tables_ok(). sql/sql_parse.cc: Binlogging of CALL (and not of the substatements of the SP). If SP returns error, we don't binlog it (see comment); we push warning in this case. Binlogging of ALTER|DROP PROCEDURE|FUNCTION with safety messages.

WL#2971 "change log-bin-trust-routine-creators=0 to apply only to functions". Indeed now that stored procedures CALL is not binlogged, but instead the invoked substatements are, the restrictions applied by log-bin-trust-routine-creators=0 are superfluous for procedures. They still need to apply to functions where function calls are written to the binlog (for example as "DO myfunc(3)"). We rename the variable to log-bin-trust-function-creators but allow the old name until some future version (and issue a warning if old name is used). mysql-test/mysql-test-run.pl: update to new option name mysql-test/mysql-test-run.sh: update to new option name mysql-test/mysql_test_run_new.c: update to new option name mysql-test/r/rpl_sp.result: result update mysql-test/t/rpl_sp-slave.opt: we need to skip this error to not hit BUG#14769 mysql-test/t/rpl_sp.test: Test update: 1) as log-bin-trust-routine-creators now affects only functions, the testing of this option, which was mainly done on procedures, is moved to functions 2) cleanup is simplified; and instead of many SHOW BINLOG EVENTS we do a big one in the end, which is more maintainable. 3) we test a few more function and procedures cases to see how they replicate. 4) removing out-of-date comments sql/item_func.cc: This warning is wrong since binlogging of functions was changed in August. If a function fails in the middle, it will be binlogged with its error code (i.e. properly). sql/mysql_priv.h: variable name changed sql/mysqld.cc: option name changes. A precision about --read-only. sql/set_var.cc: a new class sys_var_trust_routine_creators to be able to issue a "this is a deprecated variable" warning if used. sql/set_var.h: new class to be able to issue a "this is a deprecated variable" warning if used. sql/share/errmsg.txt: routine -> function sql/sp.cc: log-bin-trust-routine-creators now applies only to functions. sql/sql_parse.cc: 1) sending ER_FAILED_ROUTINE_BREAK_BINLOG is wrong since August as we don't binlog CALL anymore but instead binlog the substatements; the clear_error() goes away too as it was necessary only when we created a binlog event from the "CALL" statement. 2) log-bin-trust-routine-creators now applies only to functions. sql/sql_trigger.cc: comments.

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.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function.

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.

WL#2971 "change log-bin-trust-routine-creators=0 to apply only to functions". Indeed now that stored procedures CALL is not binlogged, but instead the invoked substatements are, the restrictions applied by log-bin-trust-routine-creators=0 are superfluous for procedures. They still need to apply to functions where function calls are written to the binlog (for example as "DO myfunc(3)"). We rename the variable to log-bin-trust-function-creators but allow the old name until some future version (and issue a warning if old name is used). mysql-test/mysql-test-run.pl: update to new option name mysql-test/mysql-test-run.sh: update to new option name mysql-test/mysql_test_run_new.c: update to new option name mysql-test/r/rpl_sp.result: result update mysql-test/t/rpl_sp-slave.opt: we need to skip this error to not hit BUG#14769 mysql-test/t/rpl_sp.test: Test update: 1) as log-bin-trust-routine-creators now affects only functions, the testing of this option, which was mainly done on procedures, is moved to functions 2) cleanup is simplified; and instead of many SHOW BINLOG EVENTS we do a big one in the end, which is more maintainable. 3) we test a few more function and procedures cases to see how they replicate. 4) removing out-of-date comments sql/item_func.cc: This warning is wrong since binlogging of functions was changed in August. If a function fails in the middle, it will be binlogged with its error code (i.e. properly). sql/mysql_priv.h: variable name changed sql/mysqld.cc: option name changes. A precision about --read-only. sql/set_var.cc: a new class sys_var_trust_routine_creators to be able to issue a "this is a deprecated variable" warning if used. sql/set_var.h: new class to be able to issue a "this is a deprecated variable" warning if used. sql/share/errmsg.txt: routine -> function sql/sp.cc: log-bin-trust-routine-creators now applies only to functions. sql/sql_parse.cc: 1) sending ER_FAILED_ROUTINE_BREAK_BINLOG is wrong since August as we don't binlog CALL anymore but instead binlog the substatements; the clear_error() goes away too as it was necessary only when we created a binlog event from the "CALL" statement. 2) log-bin-trust-routine-creators now applies only to functions. sql/sql_trigger.cc: comments.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function.

Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!"

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.

WL#2971 "change log-bin-trust-routine-creators=0 to apply only to functions". Indeed now that stored procedures CALL is not binlogged, but instead the invoked substatements are, the restrictions applied by log-bin-trust-routine-creators=0 are superfluous for procedures. They still need to apply to functions where function calls are written to the binlog (for example as "DO myfunc(3)"). We rename the variable to log-bin-trust-function-creators but allow the old name until some future version (and issue a warning if old name is used). mysql-test/mysql-test-run.pl: update to new option name mysql-test/mysql-test-run.sh: update to new option name mysql-test/mysql_test_run_new.c: update to new option name mysql-test/r/rpl_sp.result: result update mysql-test/t/rpl_sp-slave.opt: we need to skip this error to not hit BUG#14769 mysql-test/t/rpl_sp.test: Test update: 1) as log-bin-trust-routine-creators now affects only functions, the testing of this option, which was mainly done on procedures, is moved to functions 2) cleanup is simplified; and instead of many SHOW BINLOG EVENTS we do a big one in the end, which is more maintainable. 3) we test a few more function and procedures cases to see how they replicate. 4) removing out-of-date comments sql/item_func.cc: This warning is wrong since binlogging of functions was changed in August. If a function fails in the middle, it will be binlogged with its error code (i.e. properly). sql/mysql_priv.h: variable name changed sql/mysqld.cc: option name changes. A precision about --read-only. sql/set_var.cc: a new class sys_var_trust_routine_creators to be able to issue a "this is a deprecated variable" warning if used. sql/set_var.h: new class to be able to issue a "this is a deprecated variable" warning if used. sql/share/errmsg.txt: routine -> function sql/sp.cc: log-bin-trust-routine-creators now applies only to functions. sql/sql_parse.cc: 1) sending ER_FAILED_ROUTINE_BREAK_BINLOG is wrong since August as we don't binlog CALL anymore but instead binlog the substatements; the clear_error() goes away too as it was necessary only when we created a binlog event from the "CALL" statement. 2) log-bin-trust-routine-creators now applies only to functions. sql/sql_trigger.cc: comments.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function. If the function is declared to modify data and does not complete, warning "broken binlog". Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!" (see comment in code). sql/sp.cc: If binlog is on: errors if one wants to create a non-deterministic update routine (repeatability problem - note that the test is not perfect for functions) or does not have SUPER (because routines can easily be made to destroy slave's data with just CREATE ROUTINE and EXECUTE priv on master). --log-bin-trust-routine-creators removes these errors. Binlogging of CREATE PROCEDURE|FUNCTION. sql/sql_acl.cc: No thd==0 in tables_ok(). sql/sql_parse.cc: Binlogging of CALL (and not of the substatements of the SP). If SP returns error, we don't binlog it (see comment); we push warning in this case. Binlogging of ALTER|DROP PROCEDURE|FUNCTION with safety messages.

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.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function.

ERROR HY000: You do not have the SUPER privilege and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)
BUG#37975: wait_for_slave_* should increase the timeout Problem 1: tests often fail in pushbuild with a timeout when waiting for the slave to start/stop/receive error. Fix 1: Updated the wait_for_slave_* macros in the following way: - The timeout is increased by a factor ten - Refactored the macros so that wait_for_slave_param does the work for the other macros. Problem 2: Tests are often incorrectly written, lacking a source include/wait_for_slave_to_[start|stop].inc. Fix 2: Improved the chance to get it right by adding include/start_slave.inc and include/stop_slave.inc, and updated tests to use these. Problem 3: The the built-in test language command wait_for_slave_to_stop is a misnomer (does not wait for the slave io thread) and does not give as much debug info in case of failure as the otherwise equivalent macro source include/wait_for_slave_sql_to_stop.inc Fix 3: Replaced all calls to the built-in command by a call to the macro. Problem 4: Some, but not all, of the wait_for_slave_* macros had an implicit connection slave. This made some tests confusing to read, and made it more difficult to use the macro in circular replication scenarios, where the connection named master needs to wait. Fix 4: Removed the implicit connection slave from all wait_for_slave_* macros, and updated tests to use an explicit connection slave where necessary. Problem 5: The macros wait_slave_status.inc and wait_show_pattern.inc were unused. Moreover, using them is difficult and error-prone. Fix 5: remove these macros. Problem 6: log_bin_trust_function_creators_basic failed when running tests because it assumed @@global.log_bin_trust_function_creators=1, and some tests modified this variable without resetting it to its original value. Fix 6: All tests that use this variable have been updated so that they reset the value at end of test. mysql-test/extra/rpl_tests/rpl_extraMaster_Col.test: Replaced wait_for_slave_to_stop by include/wait_for_slave_sql_to_stop.inc mysql-test/extra/rpl_tests/rpl_extraSlave_Col.test: Replaced wait_for_slave_to_stop by include/wait_for_slave_sql_to_stop.inc Added connection slave since includ/wait_for_slave_sql_to_stop.inc does not do that anymore. mysql-test/extra/rpl_tests/rpl_log.test: Replaced start slave+wait_slave_status by start_slave.inc mysql-test/include/reset_master_and_slave.inc: replaced start/stop slave by start_slave.inc/stop_slave.inc mysql-test/include/sync_slave_io_with_master.inc: Improved comments and error message. mysql-test/include/wait_for_slave_io_to_stop.inc: Refactored to use wait_for_slave_param.inc.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function. If the function is declared to modify data and does not complete, warning "broken binlog". Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!" (see comment in code). sql/sp.cc: If binlog is on: errors if one wants to create a non-deterministic update routine (repeatability problem - note that the test is not perfect for functions) or does not have SUPER (because routines can easily be made to destroy slave's data with just CREATE ROUTINE and EXECUTE priv on master). --log-bin-trust-routine-creators removes these errors. Binlogging of CREATE PROCEDURE|FUNCTION. sql/sql_acl.cc: No thd==0 in tables_ok(). sql/sql_parse.cc: Binlogging of CALL (and not of the substatements of the SP). If SP returns error, we don't binlog it (see comment); we push warning in this case. Binlogging of ALTER|DROP PROCEDURE|FUNCTION with safety messages.

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.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function. If the function is declared to modify data and does not complete, warning "broken binlog". Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!"

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.

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.

Approximative fixes for BUG#2610,2611,9100 i.e. WL#2146 binlogging/replication of routines (stored procs and functions). Approximative, because it's using our binlogging way (what we call "query"-level) and this is not as good as record-level binlog (5.1) would be. It imposes several limitations to routines, and has caveats (which I'll document, and for which the server will try to issue errors but that is not always possible). Reason I don't propagate caller info to the binlog as planned is that on master and slave users may be different; even with that some caveats would remain. mysql-test/mysql-test-run.sh: In the testsuite we know what we do, we are not creating nasty routines, and breaking binlog is ok except in rpl_sp. mysql-test/r/blackhole.result: Updating results now that 4.1 has been merged mysql-test/valgrind.supp: Some suppressions for Valgrind (useful on my machine Suse 9.1); this is just adding to the already existing suppressions of pthread and dl. sql/item_func.cc: Don't binlog the substatements when executing a function. If the function is declared to modify data and does not complete, warning "broken binlog". Note that SELECT myfunc() will not be binlogged even if myfunc() updates data (will be documented); but INSERT INTO t VALUES(myfunc()) will be binlogged (what decides is if the caller gets binlogged; the function changes nothing to binlogging). sql/log_event.cc: Just making functions which can be re-used when we binlog more strings in status_vars in Query_log_event (e.g. one day "user", "host"). sql/log_event.h: comment sql/mysql_priv.h: --log-bin-trust-routine-creators sql/mysqld.cc: --log-bin-trust-routine-creators sql/set_var.cc: --log-bin-trust-routine-creators sql/share/errmsg.txt: error messages to warn about problems with routines and binlog sql/slave.cc: If in a routine, replication table inclusion/exclusion rules always answer "replicate!" (see comment in code). sql/sp.cc: If binlog is on: errors if one wants to create a non-deterministic update routine (repeatability problem - note that the test is not perfect for functions) or does not have SUPER (because routines can easily be made to destroy slave's data with just CREATE ROUTINE and EXECUTE priv on master). --log-bin-trust-routine-creators removes these errors. Binlogging of CREATE PROCEDURE|FUNCTION. sql/sql_acl.cc: No thd==0 in tables_ok(). sql/sql_parse.cc: Binlogging of CALL (and not of the substatements of the SP). If SP returns error, we don't binlog it (see comment); we push warning in this case. Binlogging of ALTER|DROP PROCEDURE|FUNCTION with safety messages.

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.

We rename the variable to log-bin-trust-function-creators but allow the old name until some future version (and issue a warning if old name is used). mysql-test/mysql-test-run.pl: update to new option name mysql-test/mysql-test-run.sh: update to new option name mysql-test/mysql_test_run_new.c: update to new option name mysql-test/r/rpl_sp.result: result update mysql-test/t/rpl_sp-slave.opt: we need to skip this error to not hit BUG#14769 mysql-test/t/rpl_sp.test: Test update: 1) as log-bin-trust-routine-creators now affects only functions, the testing of this option, which was mainly done on procedures, is moved to functions 2) cleanup is simplified; and instead of many SHOW BINLOG EVENTS we do a big one in the end, which is more maintainable. 3) we test a few more function and procedures cases to see how they replicate. 4) removing out-of-date comments sql/item_func.cc: This warning is wrong since binlogging of functions was changed in August. If a function fails in the middle, it will be binlogged with its error code (i.e. properly). sql/mysql_priv.h: variable name changed sql/mysqld.cc: option name changes. A precision about --read-only. sql/set_var.cc: a new class sys_var_trust_routine_creators to be able to issue a "this is a deprecated variable" warning if used. sql/set_var.h: new class to be able to issue a "this is a deprecated variable" warning if used. sql/share/errmsg.txt: routine -> function sql/sp.cc: log-bin-trust-routine-creators now applies only to functions. sql/sql_parse.cc: 1) sending ER_FAILED_ROUTINE_BREAK_BINLOG is wrong since August as we don't binlog CALL anymore but instead binlog the substatements; the clear_error() goes away too as it was necessary only when we created a binlog event from the "CALL" statement. 2) log-bin-trust-routine-creators now applies only to functions. sql/sql_trigger.cc: comments.

Fix for bugs #5892/6182/8751/8758/10994 (based on Antony's patch) "Triggers have the wrong namespace" "Triggers: duplicate names allowed" "Triggers: CREATE TRIGGER does not accept fully qualified names" "SHOW TRIGGERS" mysql-test/r/information_schema.result: Added tests for new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command. mysql-test/r/information_schema_db.result: INFORMATION_SCHEMA.TRIGGERS view was added. mysql-test/r/rpl_sp.result: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. mysql-test/r/trigger.result: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. Added test checking that triggers have database wide namespace. Added test for bug #8791 "Triggers: Allowed to create triggers on a subject table in a different DB". mysql-test/r/view.result: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. mysql-test/t/information_schema.test: Added tests for new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command. mysql-test/t/rpl_sp.test: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. mysql-test/t/trigger.test: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. Added test checking that triggers have database wide namespace. Added test for bug #8791 "Triggers: Allowed to create triggers on a subject table in a different DB". mysql-test/t/view.test: Now DROP TRIGGER interprets first part of trigger identifier as database name and not as table name. Adjusted tests properly. sql/handler.cc: Added .TRN tho the list of known file extensions assoicated with tables. sql/item.h: trg_action_time_type/trg_event_type enums: Added TRG_ACTION_MAX/TRG_EVENT_MAX elements which should be used instead of magical values in various loops where we iterate through all types of trigger action times or/and trigger event types. sql/lex.h: Added new symbol "TRIGGERS". sql/mysql_priv.h: Added declaration of constant holding extension for trigger name (.TRN) files. sql/mysqld.cc: Added statistical variable for SHOW TRIGGERS command. sql/share/errmsg.txt: Added error message saying that one attempts to create trigger in wrong schema. sql/sp.cc: Replaced magical values with TRG_EVENT_MAX/TRG_ACTION_MAX constants. sql/sql_base.cc: open_unireg_entry(): Now Table_triggers_list::check_n_load() has one more argument which controls whether we should prepare Table_triggers_list with fully functional triggers or load only their names. sql/sql_lex.h: Added element for new SHOW TRIGGERS command to enum_sql_command enum. sql/sql_parse.cc: prepare_schema_table(): Added support for SHOW TRIGGERS statement. sql/sql_show.cc: Added new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command. sql/sql_table.cc: mysql_rm_table_part2(): Replaced simple deletion of .TRG file with call to Table_triggers_list::drop_all_triggers which will also delete .TRN files for all triggers associated with table. sql/sql_trigger.cc: Now triggers have database wide namespace. To support it we create special .TRN file with same name as trigger for each trigger. This file contains name of trigger's table so one does not need to specify it explicitly in DROP TRIGGER. Moreover DROP TRIGGER treats first part of trigger identifier as database name now. Updated mysql_create_or_drop_trigger() routine and Table_triggers_list::create_trigger()/drop_trigger()/check_n_load() methods accordingly. Added add_table_for_trigger() routine and Table_triggers_list::drop_all_triggers() method. Added Table_triggers_list::get_trigger_info() for obtaining trigger metadata. sql/sql_trigger.h: Table_triggers_list: Use TRG_EVENT_MAX, TRG_ACTION_MAX instead of magic values. Added get_trigger_info() method for obtaining trigger's meta-data. Added drop_all_triggers() method which drops all triggers for table. Added declarations of trg_action_time_type_names/trg_event_type_names arrays which hold names of triggers action time types and event types. sql/sql_yacc.yy: Changed grammar for CREATE/DROP TRIGGER to support database wide trigger namespace. Added new SHOW TRIGGERS statement. sql/table.h: enum enum_schema_tables: Added constant for new INFORMATION_SCHEMA.TRIGGERS view.

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.

f1 CREATE DEFINER=`root`@`localhost` FUNCTION `f1`() RETURNS int(11)
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).

SHOW CREATE FUNCTION f1;
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.

BUG#37975: wait_for_slave_* should increase the timeout Problem 1: tests often fail in pushbuild with a timeout when waiting for the slave to start/stop/receive error. Fix 1: Updated the wait_for_slave_* macros in the following way: - The timeout is increased by a factor ten - Refactored the macros so that wait_for_slave_param does the work for the other macros. Problem 2: Tests are often incorrectly written, lacking a source include/wait_for_slave_to_[start|stop].inc. Fix 2: Improved the chance to get it right by adding include/start_slave.inc and include/stop_slave.inc, and updated tests to use these. Problem 3: The the built-in test language command wait_for_slave_to_stop is a misnomer (does not wait for the slave io thread) and does not give as much debug info in case of failure as the otherwise equivalent macro source include/wait_for_slave_sql_to_stop.inc Fix 3: Replaced all calls to the built-in command by a call to the macro. Problem 4: Some, but not all, of the wait_for_slave_* macros had an implicit connection slave. This made some tests confusing to read, and made it more difficult to use the macro in circular replication scenarios, where the connection named master needs to wait. Fix 4: Removed the implicit connection slave from all wait_for_slave_* macros, and updated tests to use an explicit connection slave where necessary. Problem 5: The macros wait_slave_status.inc and wait_show_pattern.inc were unused. Moreover, using them is difficult and error-prone. Fix 5: remove these macros. Problem 6: log_bin_trust_function_creators_basic failed when running tests because it assumed @@global.log_bin_trust_function_creators=1, and some tests modified this variable without resetting it to its original value. Fix 6: All tests that use this variable have been updated so that they reset the value at end of test. mysql-test/extra/rpl_tests/rpl_extraMaster_Col.test: Replaced wait_for_slave_to_stop by include/wait_for_slave_sql_to_stop.inc mysql-test/extra/rpl_tests/rpl_extraSlave_Col.test: Replaced wait_for_slave_to_stop by include/wait_for_slave_sql_to_stop.inc Added connection slave since includ/wait_for_slave_sql_to_stop.inc does not do that anymore. mysql-test/extra/rpl_tests/rpl_log.test: Replaced start slave+wait_slave_status by start_slave.inc mysql-test/include/reset_master_and_slave.inc: replaced start/stop slave by start_slave.inc/stop_slave.inc mysql-test/include/sync_slave_io_with_master.inc: Improved comments and error message. mysql-test/include/wait_for_slave_io_to_stop.inc: Refactored to use wait_for_slave_param.inc.

Bug#41371 Select returns 1 row with condition "col is not null and col is null" For application compatibility reasons MySQL converts "<autoincrement_column> IS NULL" predicates to "<autoincrement_column> = LAST_INSERT_ID()" in the first SELECT following an INSERT regardless of whether they're top level predicates or not. This causes wrong and obscure results when these predicates are combined with others on the same columns. Fixed by only doing the transformation on a single top-level predicate if a special SQL mode is turned on (sql_auto_is_null). Also made sql_auto_is_null off by default. per-file comments: mysql-test/r/func_isnull.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" test result updated mysql-test/t/func_isnull.test Bug#41371 Select returns 1 row with condition "col is not null and col is null" test case added sql/mysqld.cc Bug#41371 Select returns 1 row with condition "col is not null and col is null" sql_auto_is_null now is OFF by default. sql/sql_select.cc Bug#41371 Select returns 1 row with condition "col is not null and col is null" remove_eq_conds() split in two parts - one only checks the upper condition, the req_remove_eq_conds() recursively checks all the condition tree. mysql-test/extra/rpl_tests/rpl_insert_id.test Bug#41371 Select returns 1 row with condition "col is not null and col is null" test fixed (set the sql_auto_is_null variable) mysql-test/r/mysqlbinlog.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/r/mysqlbinlog2.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/r/odbc.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/r/query_cache.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/r/user_var-binlog.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/binlog/r/binlog_row_ctype_ucs.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/binlog/r/binlog_stm_ctype_ucs.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/rpl/r/rpl_insert_id.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/rpl/r/rpl_row_mysqlbinlog.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/rpl/r/rpl_sp.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/t/odbc.test Bug#41371 Select returns 1 row with condition "col is not null and col is null" test fixed (set the sql_auto_is_null variable)

Fix for bug#39182: Binary log producing incompatible character set query from stored procedure. Problem: we replace all references to local variables in stored procedures with NAME_CONST(name, value) logging to the binary log. However, if the value's collation differs we might get an 'illegal mix of collation' error as we don't pass the collation to the function. Fix: pass the value's collation to NAME_CONST(). Note: actually we should pass to NAME_CONST() the value's derivation as well. It's impossible without the parser modifying. Now we always set the derivation to DERIVATION_IMPLICIT, the same as local variables have. mysql-test/r/binlog.result: Fix for bug#39182: Binary log producing incompatible character set query from stored procedure. - test result. mysql-test/r/ctype_cp932_binlog.result: Fix for bug#39182: Binary log producing incompatible character set query from stored procedure. - results adjusted. mysql-test/r/rpl_sp.result: Fix for bug#39182: Binary log producing incompatible character set query from stored procedure. - results adjusted. mysql-test/t/binlog.test: Fix for bug#39182: Binary log producing incompatible character set query from stored procedure. - test case. sql/item.cc: Fix for bug#39182: Binary log producing incompatible character set query from stored procedure. - allow NAME_CONST() to get _charset'foo' COLLATE 'bar' strings (see Item_func_set_collation). sql/sp_head.cc: Fix for bug#39182: Binary log producing incompatible character set query from stored procedure. - pass the value's collation to NAME_CONST().

Bug#36570: Parse error of CREATE PROCEDURE stmt with comments on \ slave The stored-routine code took the contents of the (lowest) parser and copied it directly to the binlog, which causes problems if there is a special case of interpretation at the parser level -- which there is, in the "/*!VER */" comments. The trailing "*/" caused errors on the slave, naturally. Now, since by that point we have /properly/ created parse-tree (as the rest of the server should do!) for the stored-routine CREATE, we can construct a perfect statement from that information, instead of writing uncertain information from an unknown parser state. Fortunately, there's already a function nearby that does exactly that. --- Update for Bug#36570. Qualify routine names with db name when writing to the binlog ONLY if the source text is qualified. mysql-test/r/binlog_innodb.result: Offsets changed due to quoting. --- New offset to account for db-qualified names. mysql-test/r/ctype_cp932_binlog.result: Offsets changed due to quoting. --- Qualify routine names with DB. Offsets change also. mysql-test/r/mysqlbinlog.result: Case changed in result due to interpretation of data instead of literal recitation. --- Qualify procedure name with db. mysql-test/r/rpl_sp.result: Offsets changed due to quoting. Added tests. --- Qualify routine names with DB if qualified in query. Offsets change also. mysql-test/t/rpl_sp.test: Add version-limiting quotes to exercise bug#36570. Test that backtick-quoted identifiers and labels work also. --- Use different db to show qualification works. Qualify routine names with DB if qualified in query. sql/sp.cc: In create_string, we may not have a sp_name parameter yet, so instead pass the char* and length of the only member we'd get out of it. Having done that, we can use the same function to write the CREATE (FUNC|TRIG|PROC) statement to the binlog as we always used to display the statement to the user. --- Make the db name part of the CREATE string if it is specified. Specify it in part of writing to the binlog when creating a new routine. sql/sp_head.cc: Set the sp_head m_explicit_name member as the sp_name member is set. We can not peek at this later, as the sp_name is gone by then. sql/sp_head.h: Add a member to track whether the name is qualified with the database.

Apply and review: 3655 Jon Olav Hauglid 2009-10-19 Bug #30977 Concurrent statement using stored function and DROP FUNCTION breaks SBR Bug #48246 assert in close_thread_table Implement a fix for: Bug #41804 purge stored procedure cache causes mysterious hang for many minutes Bug #49972 Crash in prepared statements The problem was that concurrent execution of DML statements that use stored functions and DDL statements that drop/modify the same function might result in incorrect binary log in statement (and mixed) mode and therefore break replication. This patch fixes the problem by introducing metadata locking for stored procedures and functions. This is similar to what is done in Bug#25144 for views. Procedures and functions now are locked using metadata locks until the transaction is either committed or rolled back. This prevents other statements from modifying the procedure/function while it is being executed. This provides commit ordering - guaranteeing serializability across multiple transactions and thus fixes the reported binlog problem. Note that we do not take locks for top-level CALLs. This means that procedures called directly are not protected from changes by simultaneous DDL operations so they are executed at the state they had at the time of the CALL. By not taking locks for top-level CALLs, we still allow transactions to be started inside procedures. This patch also changes stored procedure cache invalidation. Upon a change of cache version, we no longer invalidate the entire cache, but only those routines which we use, only when a statement is executed that uses them. This patch also changes the logic of prepared statement validation. A stored procedure used by a prepared statement is now validated only once a metadata lock has been acquired. A version mismatch causes a flush of the obsolete routine from the cache and statement reprepare. Incompatible changes: 1) ER_LOCK_DEADLOCK is reported for a transaction trying to access a procedure/function that is locked by a DDL operation in another connection. 2) Procedure/function DDL operations are now prohibited in LOCK TABLES mode as exclusive locks must be taken all at once and LOCK TABLES provides no way to specifiy procedures/functions to be locked. Test cases have been added to sp-lock.test and rpl_sp.test. Work on this bug has very much been a team effort and this patch includes and is based on contributions from Davi Arnaut, Dmitry Lenev, Magne Mæhre and Konstantin Osipov. mysql-test/r/ps_ddl.result: Update results (Bug#30977). mysql-test/r/ps_ddl1.result: Update results (Bug#30977). mysql-test/r/sp-error.result: Update results (Bug#30977). mysql-test/r/sp-lock.result: Update results (Bug#30977). mysql-test/suite/rpl/r/rpl_sp.result: Update results (Bug#30977). mysql-test/suite/rpl/t/rpl_sp.test: Add a test case for Bug#30977. mysql-test/t/ps_ddl.test: Update comments. We no longer re-prepare a prepared statement when a stored procedure used in top-level CALL is changed. mysql-test/t/ps_ddl1.test: Modifying stored procedure p1 no longer invalidates prepared statement "call p1" -- we can re-use the prepared statement without invalidation. mysql-test/t/sp-error.test: Use a constant for an error value. mysql-test/t/sp-lock.test: Add test coverage for Bug#30977. sql/lock.cc: Implement lock_routine_name() - a way to acquire an exclusive metadata lock (ex- name-lock) on stored procedure/function. sql/sp.cc: Change semantics of sp_cache_routine() -- now it has an option to make sure that the routine that is cached is up to date (has the latest sp cache version). Add sp_cache_invalidate() to sp_drop_routine(), where it was missing (a bug!). Acquire metadata locks for SP DDL (ALTER/CREATE/DROP). This is the core of the fix for Bug#30977. Since caching and cache invalidation scheme was changed, make sure we don't invalidate the SP cache in the middle of a stored routine execution. At the same time, make sure we don't access stale data due to lack of invalidation. For that, change ALTER FUNCTION/PROCEDURE to not use the cache, and SHOW PROCEDURE CODE/SHOW CREATE PROCEDURE/FUNCTION to always read an up to date version of the routine from the cache. sql/sp.h: Add a helper wrapper around sp_cache_routine(). sql/sp_cache.cc: Implement new sp_cache_version() and sp_cache_flush_obsolete(). Now we flush stale routines individually, rather than all at once. sql/sp_cache.h: Update signatures of sp_cache_version() and sp_cache_flush_obsolete(). sql/sp_head.cc: Add a default initialization of sp_head::m_sp_cache_version. Remove a redundant sp_head::create(). sql/sp_head.h: Add m_sp_cache_version to sp_head class - we now keep track of every routine in the stored procedure cache, rather than of the entire cache. sql/sql_base.cc: Implement prelocking for stored routines. Validate stored routines after they were locked. Flush obsolete routines upon next access, one by one, not all at once (Bug#41804). Style fixes. sql/sql_class.h: Rename a Open_table_context method. sql/sql_parse.cc: Make sure stored procedures DDL commits the active transaction (issues an implicit commit before and after). Remove sp_head::create(), a pure redundancy. Move the semantical check during alter routine inside sp_update_routine() code in order to: - avoid using SP cache during update, it may be obsolete. - speed up and simplify the update procedure. Remove sp_cache_flush_obsolete() calls, we no longer flush the entire cache, ever, stale routines are flushed before next use, one at a time. sql/sql_prepare.cc: Move routine metadata validation to open_and_process_routine(). Fix Bug#49972 (don't swap flags at reprepare). Reset Sroutine_hash_entries in reinit_stmt_before_use(). Remove SP cache invalidation, it's now done by open_tables(). sql/sql_show.cc: Fix a warning: remove an unused label. sql/sql_table.cc: Reset mdl_request.ticket for tickets acquired for routines inlined through a view, in CHECK TABLE statement, to satisfy an MDL assert. sql/sql_update.cc: Move the cleanup of "translation items" to close_tables_for_reopen(), since it's needed in all cases when we back off, not just the back-off in multi-update. This fixes a bug when the server would crash on attempt to back off when opening tables for a statement that uses information_schema tables.

Patch that changes approach to how we acquire metadata locks for DML statements and changes the way MDL locks are acquired/granted in contended case. Instead of backing-off when a lock conflict is encountered and waiting for it to go away before restarting open_tables() process we now wait for lock to be released without releasing any previously acquired locks. If conflicting lock goes away we resume opening tables. If waiting leads to a deadlock we try to resolve it by backing-off and restarting open_tables() immediately. As result both waiting for possibility to acquire and acquiring of a metadata lock now always happen within the same MDL API call. This has allowed to make release of a lock and granting it to the most appropriate pending request an atomic operation. Thanks to this it became possible to wake up during release of lock only those waiters which requests can be satisfied at the moment as well as wake up only one waiter in case when granting its request would prevent all other requests from being satisfied. This solves thundering herd problem which occured in cases when we were releasing some lock and woke up many waiters for SNRW or X locks (this was the issue in bug#52289 "performance regression for MyISAM in sysbench OLTP_RW test". This also allowed to implement more fair (FIFO) scheduling among waiters with the same priority. It also opens the door for introducing new types of requests for metadata locks such as low-prio SNRW lock which is necessary in order to support LOCK TABLES LOW_PRIORITY WRITE. Notice that after this sometimes can report ER_LOCK_DEADLOCK error in cases in which it has not happened before. Particularly we will always report this error if waiting for conflicting lock has happened in the middle of transaction and resulted in a deadlock. Before this patch the error was not reported if deadlock could have been resolved by backing off all metadata locks acquired by the current statement. mysql-test/r/mdl_sync.result: Added test coverage for some aspects of deadlock handling in metadata locking subsystem. Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/r/sp_sync.result: Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/suite/perfschema/r/dml_setup_instruments.result: Adjusted test results after renaming MDL_context:: m_waiting_for_lock rwlock to m_LOCK_waiting_for. mysql-test/suite/rpl/r/rpl_sp.result: Adjusted test case after implementing new approach to acquiring metadata locks in open_tables(). We no longer release all MDL locks acquired by statement before waiting for conflicting lock to go away. As result DROP FUNCTION statement has to wait for DML statement which managed to acquire metadata lock on function being dropped and now waits for other conflicting metadata lock to go away. mysql-test/suite/rpl/t/rpl_sp.test: Adjusted test case after implementing new approach to acquiring metadata locks in open_tables(). We no longer release all MDL locks acquired by statement before waiting for conflicting lock to go away. As result DROP FUNCTION statement has to wait for DML statement which managed to acquire metadata lock on function being dropped and now waits for other conflicting metadata lock to go away. mysql-test/t/mdl_sync.test: Added test coverage for some aspects of deadlock handling in metadata locking subsystem. Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/t/sp_sync.test: Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). sql/mdl.cc: Changed MDL subsystem to support new approach to acquring metadata locks in open tables and more fair and efficient scheduling of metadata locks. To implement this: - Made releasing of the lock and granting it to the most appropriate pending request atomic operation. As result it became possible to wake up only those waiters requests from which can be satisfied at the moment as well as wake-up only one waiter in case when granting its request would prevent all other requests from being satisfied. This solved thundering herd problem which occured in cases when we were releasing some lock and woke up many waiters for SNRW or X locks (this was the issue in Bug #52289 "performance regression for MyISAM in sysbench OLTP_RW test". To emphasize above changes wake_up_waiters() was renamed to MDL_context::reschedule_waiters(). - Changed code to add tickets for new requests to the back of waiters queue and to select tickets to be satisfied from the head of the queue if possible (this makes scheduling of requests with the same priority fair). To be able to do this efficiently we now use for waiting and granted queues version of I_P_List class which provides fast push_back() method. - Members and methods of MDL_context related to sending and waiting for signal were moved to separate MDL_wait class. - Since in order to avoid race conditions we must grant the lock only to the context which was not chosen as a victim of deadlock, killed or aborted due to timeout MDL_wait::set_status() (former awake()) was changed not to send signal if signal slot is already occupied and to indicate this fact through its return value. As another consequence MDL_wait::timed_wait() method was changed to handle timeout (optionally) and abort due to kill as signals which make signal slot occupied. - Renamed MDL_context::acquire_lock_impl() to acquire_lock(). Changed it to be able correctly process requests for shared locks when there are open HANDLERs, made this method more optimized for acquisition of shared locks. As part of this change moved code common between try_acquire_lock() and acquire_lock() to new try_acquire_lock_impl() method. Also adjusted acquire_lock()'s code to take into account the fact that in cases when lock is granted as result of MDL_context::reschedule_waiters() call (i.e. when it is granted after waiting for lock conflict to go away) updating MDL_lock state is responsibility of the thread calling reschedule_waiters(). - Changed MDL_context::find_deadlock() to send VICTIM signal even if victim is the context which has initiated deadlock detection. This is required in order to avoid races in cases when the same context simultaneously is chosen as a victim and its request for lock is satisfied. As result return value of this method became unnecessary and it was changed to return void. Adjusted MDL_lock::find_deadlock() method to take into account that now there can be a discrepancy between MDL_context::m_waiting_for value being set and real state of the ticket this member points to. - Renamed MDL_context::m_waiting_for_lock to m_LOCK_waiting_for and MDL_context::stop_waiting() to done_waiting_for(). - Finally, removed MDL_context::wait_for_lock() method. sql/mdl.h: Changed MDL subsystem to support new approach to acquring metadata locks in open tables and more fair and efficient scheduling of metadata locks. To implement this: - Members and methods of MDL_context related to sending and waiting for signal were moved to separate MDL_wait class. - Since now in order to avoid race conditions we must grant the lock only to the context which was not chosen as a victim of deadlock, killed or aborted due to timeout MDL_wait::set_status (former awake()) was changed not to send signal if signal slot is already occupied and to indicate this fact through its return value. Also NORMAL_WAKE_UP signal became GRANTED, and timeouts and aborts due to kill became full blown signals rather than simple return values. - MDL_wait::timed_wait() now takes extra parameter that indicates whether signal should be set if timeout is reached. - Enabled fast push_back() operation in MDL_context::m_tickets list to make move_ticket_after_trans_sentinel() method more efficient. - Removed MDL_context::wait_for_lock() method. - Renamed MDL_context::m_waiting_for_lock to m_LOCK_waiting_for and MDL_context::stop_waiting() to done_waiting_for(). - MDL_context::acquire_lock_impl() became acquire_lock(). - Introduced MDL_context::try_acquire_lock_impl() as a place for code shared by try_acquire_lock and acquire_lock(). - Due to fact that now VICTIM signal is sent even if victim is the context which has initiated deadlock detection find_deadlock() no longer needs a return value. sql/sql_base.cc: Implemented new approach to acquiring metadata locks in open_tables(). We no longer perform back-off when conflicting metadata lock is encountered. Instead we wait for this lock to go away while holding all locks which were acquired so far. Back-off is only used in situation when further waiting will cause a deadlock which could be avoided by performing back-off and restarting open_tables() process. Absence of waiting between back-off and restart of acquiring metadata locks can't lead to livelocks as MDL subsystem was changed to make release of lock and granting it to waiting lock an atomic action, so back-off will automatically give way to other participants of deadlock loop. Accordingly: - open_table_get_mdl_lock() and open_and_process_routine() were changed to wait for conflicting metadata lock to go away without back-off. Only if such wait leads to a deadlock back-off is requested. As part of this change new error handler class was introduced which converts, if possible, ER_LOCK_DEADLOCK error to a request for back-off and re-start of open_tables() process. - Open_table_context::recover_from_failed_open() was changed not to wait in case of metadata lock conflict. Instead we immediately proceed to re-acquiring locks. - Open_table_context::request_backoff_action() now always emits error if back-off is requested in the middle of transaction as we can't be sure that releasing lock which were acquired only by current statement will resolve a deadlock. Before this patch such situations were successfully detected thanks to the fact that we called MDL_context::wait_for_lock() method in recover_from_failed_open(). - In order to avoid deadlocks open_tables() code was adjusted to flush open HANDLERs for which there are pending requests for X locks before restarting the process of acquiring metadata locks. - Changed close_tables_for_reopen() not to reset MDL_request for tables belonging to the tail of prelocking list. It is no longer necessary as these MDL_request objects won't be used for any waiting. - Adjusted comment in tdc_wait_for_old_version() to avoid mentioning removed MDL_context::wait_for_lock() method. sql/sql_base.h: As we no longer wait for conflicting metadata lock away in Open_table_context::recover_from_failed_open() method, Open_table_context::OT_WAIT_MDL_LOCK action was renamed to OT_MDL_CONFLICT. Also Open_table_context::m_failed_mdl_request became unnecessary and was removed. sql/sql_plist.h: Extended I_P_List template to support efficient push_back() operation if it is parameterized with an appropriate policy class. sql/sql_show.cc: Adjusted code after removal of MDL_context::wait_for_lock() method. Now if one needs to acquire metadata lock with waiting one has to use a variant of MDL_context::acquire_lock() method.

We no longer re-prepare a prepared statement when a stored procedure used in top-level CALL is changed. mysql-test/t/ps_ddl1.test: Modifying stored procedure p1 no longer invalidates prepared statement "call p1" -- we can re-use the prepared statement without invalidation. mysql-test/t/sp-error.test: Use a constant for an error value. mysql-test/t/sp-lock.test: Add test coverage for Bug#30977. sql/lock.cc: Implement lock_routine_name() - a way to acquire an exclusive metadata lock (ex- name-lock) on stored procedure/function. sql/sp.cc: Change semantics of sp_cache_routine() -- now it has an option to make sure that the routine that is cached is up to date (has the latest sp cache version). Add sp_cache_invalidate() to sp_drop_routine(), where it was missing (a bug!). Acquire metadata locks for SP DDL (ALTER/CREATE/DROP). This is the core of the fix for Bug#30977. Since caching and cache invalidation scheme was changed, make sure we don't invalidate the SP cache in the middle of a stored routine execution. At the same time, make sure we don't access stale data due to lack of invalidation. For that, change ALTER FUNCTION/PROCEDURE to not use the cache, and SHOW PROCEDURE CODE/SHOW CREATE PROCEDURE/FUNCTION to always read an up to date version of the routine from the cache. sql/sp.h: Add a helper wrapper around sp_cache_routine(). sql/sp_cache.cc: Implement new sp_cache_version() and sp_cache_flush_obsolete(). Now we flush stale routines individually, rather than all at once. sql/sp_cache.h: Update signatures of sp_cache_version() and sp_cache_flush_obsolete(). sql/sp_head.cc: Add a default initialization of sp_head::m_sp_cache_version. Remove a redundant sp_head::create(). sql/sp_head.h: Add m_sp_cache_version to sp_head class - we now keep track of every routine in the stored procedure cache, rather than of the entire cache. sql/sql_base.cc: Implement prelocking for stored routines. Validate stored routines after they were locked. Flush obsolete routines upon next access, one by one, not all at once (Bug#41804). Style fixes. sql/sql_class.h: Rename a Open_table_context method. sql/sql_parse.cc: Make sure stored procedures DDL commits the active transaction (issues an implicit commit before and after). Remove sp_head::create(), a pure redundancy. Move the semantical check during alter routine inside sp_update_routine() code in order to: - avoid using SP cache during update, it may be obsolete. - speed up and simplify the update procedure. Remove sp_cache_flush_obsolete() calls, we no longer flush the entire cache, ever, stale routines are flushed before next use, one at a time. sql/sql_prepare.cc: Move routine metadata validation to open_and_process_routine(). Fix Bug#49972 (don't swap flags at reprepare). Reset Sroutine_hash_entries in reinit_stmt_before_use(). Remove SP cache invalidation, it's now done by open_tables(). sql/sql_show.cc: Fix a warning: remove an unused label. sql/sql_table.cc: Reset mdl_request.ticket for tickets acquired for routines inlined through a view, in CHECK TABLE statement, to satisfy an MDL assert. sql/sql_update.cc: Move the cleanup of "translation items" to close_tables_for_reopen(), since it's needed in all cases when we back off, not just the back-off in multi-update. This fixes a bug when the server would crash on attempt to back off when opening tables for a statement that uses information_schema tables.

Patch that changes approach to how we acquire metadata locks for DML statements and changes the way MDL locks are acquired/granted in contended case. Instead of backing-off when a lock conflict is encountered and waiting for it to go away before restarting open_tables() process we now wait for lock to be released without releasing any previously acquired locks. If conflicting lock goes away we resume opening tables. If waiting leads to a deadlock we try to resolve it by backing-off and restarting open_tables() immediately. As result both waiting for possibility to acquire and acquiring of a metadata lock now always happen within the same MDL API call. This has allowed to make release of a lock and granting it to the most appropriate pending request an atomic operation. Thanks to this it became possible to wake up during release of lock only those waiters which requests can be satisfied at the moment as well as wake up only one waiter in case when granting its request would prevent all other requests from being satisfied. This solves thundering herd problem which occured in cases when we were releasing some lock and woke up many waiters for SNRW or X locks (this was the issue in bug#52289 "performance regression for MyISAM in sysbench OLTP_RW test". This also allowed to implement more fair (FIFO) scheduling among waiters with the same priority. It also opens the door for introducing new types of requests for metadata locks such as low-prio SNRW lock which is necessary in order to support LOCK TABLES LOW_PRIORITY WRITE. Notice that after this sometimes can report ER_LOCK_DEADLOCK error in cases in which it has not happened before. Particularly we will always report this error if waiting for conflicting lock has happened in the middle of transaction and resulted in a deadlock. Before this patch the error was not reported if deadlock could have been resolved by backing off all metadata locks acquired by the current statement. mysql-test/r/mdl_sync.result: Added test coverage for some aspects of deadlock handling in metadata locking subsystem. Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/r/sp_sync.result: Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/suite/perfschema/r/dml_setup_instruments.result: Adjusted test results after renaming MDL_context:: m_waiting_for_lock rwlock to m_LOCK_waiting_for. mysql-test/suite/rpl/r/rpl_sp.result: Adjusted test case after implementing new approach to acquiring metadata locks in open_tables(). We no longer release all MDL locks acquired by statement before waiting for conflicting lock to go away. As result DROP FUNCTION statement has to wait for DML statement which managed to acquire metadata lock on function being dropped and now waits for other conflicting metadata lock to go away. mysql-test/suite/rpl/t/rpl_sp.test: Adjusted test case after implementing new approach to acquiring metadata locks in open_tables(). We no longer release all MDL locks acquired by statement before waiting for conflicting lock to go away. As result DROP FUNCTION statement has to wait for DML statement which managed to acquire metadata lock on function being dropped and now waits for other conflicting metadata lock to go away. mysql-test/t/mdl_sync.test: Added test coverage for some aspects of deadlock handling in metadata locking subsystem. Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/t/sp_sync.test: Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). sql/mdl.cc: Changed MDL subsystem to support new approach to acquring metadata locks in open tables and more fair and efficient scheduling of metadata locks. To implement this: - Made releasing of the lock and granting it to the most appropriate pending request atomic operation. As result it became possible to wake up only those waiters requests from which can be satisfied at the moment as well as wake-up only one waiter in case when granting its request would prevent all other requests from being satisfied. This solved thundering herd problem which occured in cases when we were releasing some lock and woke up many waiters for SNRW or X locks (this was the issue in Bug #52289 "performance regression for MyISAM in sysbench OLTP_RW test". To emphasize above changes wake_up_waiters() was renamed to MDL_context::reschedule_waiters(). - Changed code to add tickets for new requests to the back of waiters queue and to select tickets to be satisfied from the head of the queue if possible (this makes scheduling of requests with the same priority fair). To be able to do this efficiently we now use for waiting and granted queues version of I_P_List class which provides fast push_back() method. - Members and methods of MDL_context related to sending and waiting for signal were moved to separate MDL_wait class. - Since in order to avoid race conditions we must grant the lock only to the context which was not chosen as a victim of deadlock, killed or aborted due to timeout MDL_wait::set_status() (former awake()) was changed not to send signal if signal slot is already occupied and to indicate this fact through its return value. As another consequence MDL_wait::timed_wait() method was changed to handle timeout (optionally) and abort due to kill as signals which make signal slot occupied. - Renamed MDL_context::acquire_lock_impl() to acquire_lock(). Changed it to be able correctly process requests for shared locks when there are open HANDLERs, made this method more optimized for acquisition of shared locks. As part of this change moved code common between try_acquire_lock() and acquire_lock() to new try_acquire_lock_impl() method. Also adjusted acquire_lock()'s code to take into account the fact that in cases when lock is granted as result of MDL_context::reschedule_waiters() call (i.e. when it is granted after waiting for lock conflict to go away) updating MDL_lock state is responsibility of the thread calling reschedule_waiters(). - Changed MDL_context::find_deadlock() to send VICTIM signal even if victim is the context which has initiated deadlock detection. This is required in order to avoid races in cases when the same context simultaneously is chosen as a victim and its request for lock is satisfied. As result return value of this method became unnecessary and it was changed to return void. Adjusted MDL_lock::find_deadlock() method to take into account that now there can be a discrepancy between MDL_context::m_waiting_for value being set and real state of the ticket this member points to. - Renamed MDL_context::m_waiting_for_lock to m_LOCK_waiting_for and MDL_context::stop_waiting() to done_waiting_for(). - Finally, removed MDL_context::wait_for_lock() method. sql/mdl.h: Changed MDL subsystem to support new approach to acquring metadata locks in open tables and more fair and efficient scheduling of metadata locks. To implement this: - Members and methods of MDL_context related to sending and waiting for signal were moved to separate MDL_wait class. - Since now in order to avoid race conditions we must grant the lock only to the context which was not chosen as a victim of deadlock, killed or aborted due to timeout MDL_wait::set_status (former awake()) was changed not to send signal if signal slot is already occupied and to indicate this fact through its return value. Also NORMAL_WAKE_UP signal became GRANTED, and timeouts and aborts due to kill became full blown signals rather than simple return values. - MDL_wait::timed_wait() now takes extra parameter that indicates whether signal should be set if timeout is reached. - Enabled fast push_back() operation in MDL_context::m_tickets list to make move_ticket_after_trans_sentinel() method more efficient. - Removed MDL_context::wait_for_lock() method. - Renamed MDL_context::m_waiting_for_lock to m_LOCK_waiting_for and MDL_context::stop_waiting() to done_waiting_for(). - MDL_context::acquire_lock_impl() became acquire_lock(). - Introduced MDL_context::try_acquire_lock_impl() as a place for code shared by try_acquire_lock and acquire_lock(). - Due to fact that now VICTIM signal is sent even if victim is the context which has initiated deadlock detection find_deadlock() no longer needs a return value. sql/sql_base.cc: Implemented new approach to acquiring metadata locks in open_tables(). We no longer perform back-off when conflicting metadata lock is encountered. Instead we wait for this lock to go away while holding all locks which were acquired so far. Back-off is only used in situation when further waiting will cause a deadlock which could be avoided by performing back-off and restarting open_tables() process. Absence of waiting between back-off and restart of acquiring metadata locks can't lead to livelocks as MDL subsystem was changed to make release of lock and granting it to waiting lock an atomic action, so back-off will automatically give way to other participants of deadlock loop. Accordingly: - open_table_get_mdl_lock() and open_and_process_routine() were changed to wait for conflicting metadata lock to go away without back-off. Only if such wait leads to a deadlock back-off is requested. As part of this change new error handler class was introduced which converts, if possible, ER_LOCK_DEADLOCK error to a request for back-off and re-start of open_tables() process. - Open_table_context::recover_from_failed_open() was changed not to wait in case of metadata lock conflict. Instead we immediately proceed to re-acquiring locks. - Open_table_context::request_backoff_action() now always emits error if back-off is requested in the middle of transaction as we can't be sure that releasing lock which were acquired only by current statement will resolve a deadlock. Before this patch such situations were successfully detected thanks to the fact that we called MDL_context::wait_for_lock() method in recover_from_failed_open(). - In order to avoid deadlocks open_tables() code was adjusted to flush open HANDLERs for which there are pending requests for X locks before restarting the process of acquiring metadata locks. - Changed close_tables_for_reopen() not to reset MDL_request for tables belonging to the tail of prelocking list. It is no longer necessary as these MDL_request objects won't be used for any waiting. - Adjusted comment in tdc_wait_for_old_version() to avoid mentioning removed MDL_context::wait_for_lock() method. sql/sql_base.h: As we no longer wait for conflicting metadata lock away in Open_table_context::recover_from_failed_open() method, Open_table_context::OT_WAIT_MDL_LOCK action was renamed to OT_MDL_CONFLICT. Also Open_table_context::m_failed_mdl_request became unnecessary and was removed. sql/sql_plist.h: Extended I_P_List template to support efficient push_back() operation if it is parameterized with an appropriate policy class. sql/sql_show.cc: Adjusted code after removal of MDL_context::wait_for_lock() method. Now if one needs to acquire metadata lock with waiting one has to use a variant of MDL_context::acquire_lock() method.

# Check that 'drop function f1' gets blocked.
Apply and review: 3655 Jon Olav Hauglid 2009-10-19 Bug #30977 Concurrent statement using stored function and DROP FUNCTION breaks SBR Bug #48246 assert in close_thread_table Implement a fix for: Bug #41804 purge stored procedure cache causes mysterious hang for many minutes Bug #49972 Crash in prepared statements The problem was that concurrent execution of DML statements that use stored functions and DDL statements that drop/modify the same function might result in incorrect binary log in statement (and mixed) mode and therefore break replication. This patch fixes the problem by introducing metadata locking for stored procedures and functions. This is similar to what is done in Bug#25144 for views. Procedures and functions now are locked using metadata locks until the transaction is either committed or rolled back. This prevents other statements from modifying the procedure/function while it is being executed. This provides commit ordering - guaranteeing serializability across multiple transactions and thus fixes the reported binlog problem. Note that we do not take locks for top-level CALLs. This means that procedures called directly are not protected from changes by simultaneous DDL operations so they are executed at the state they had at the time of the CALL. By not taking locks for top-level CALLs, we still allow transactions to be started inside procedures. This patch also changes stored procedure cache invalidation. Upon a change of cache version, we no longer invalidate the entire cache, but only those routines which we use, only when a statement is executed that uses them. This patch also changes the logic of prepared statement validation. A stored procedure used by a prepared statement is now validated only once a metadata lock has been acquired. A version mismatch causes a flush of the obsolete routine from the cache and statement reprepare. Incompatible changes: 1) ER_LOCK_DEADLOCK is reported for a transaction trying to access a procedure/function that is locked by a DDL operation in another connection. 2) Procedure/function DDL operations are now prohibited in LOCK TABLES mode as exclusive locks must be taken all at once and LOCK TABLES provides no way to specifiy procedures/functions to be locked.

Apply and review: 3655 Jon Olav Hauglid 2009-10-19 Bug #30977 Concurrent statement using stored function and DROP FUNCTION breaks SBR Bug #48246 assert in close_thread_table Implement a fix for: Bug #41804 purge stored procedure cache causes mysterious hang for many minutes Bug #49972 Crash in prepared statements The problem was that concurrent execution of DML statements that use stored functions and DDL statements that drop/modify the same function might result in incorrect binary log in statement (and mixed) mode and therefore break replication. This patch fixes the problem by introducing metadata locking for stored procedures and functions. This is similar to what is done in Bug#25144 for views. Procedures and functions now are locked using metadata locks until the transaction is either committed or rolled back. This prevents other statements from modifying the procedure/function while it is being executed. This provides commit ordering - guaranteeing serializability across multiple transactions and thus fixes the reported binlog problem. Note that we do not take locks for top-level CALLs. This means that procedures called directly are not protected from changes by simultaneous DDL operations so they are executed at the state they had at the time of the CALL. By not taking locks for top-level CALLs, we still allow transactions to be started inside procedures. This patch also changes stored procedure cache invalidation. Upon a change of cache version, we no longer invalidate the entire cache, but only those routines which we use, only when a statement is executed that uses them. This patch also changes the logic of prepared statement validation. A stored procedure used by a prepared statement is now validated only once a metadata lock has been acquired. A version mismatch causes a flush of the obsolete routine from the cache and statement reprepare. Incompatible changes: 1) ER_LOCK_DEADLOCK is reported for a transaction trying to access a procedure/function that is locked by a DDL operation in another connection. 2) Procedure/function DDL operations are now prohibited in LOCK TABLES mode as exclusive locks must be taken all at once and LOCK TABLES provides no way to specifiy procedures/functions to be locked. Test cases have been added to sp-lock.test and rpl_sp.test. Work on this bug has very much been a team effort and this patch includes and is based on contributions from Davi Arnaut, Dmitry Lenev, Magne Mæhre and Konstantin Osipov. mysql-test/r/ps_ddl.result: Update results (Bug#30977). mysql-test/r/ps_ddl1.result: Update results (Bug#30977). mysql-test/r/sp-error.result: Update results (Bug#30977). mysql-test/r/sp-lock.result: Update results (Bug#30977). mysql-test/suite/rpl/r/rpl_sp.result: Update results (Bug#30977). mysql-test/suite/rpl/t/rpl_sp.test: Add a test case for Bug#30977. mysql-test/t/ps_ddl.test: Update comments. We no longer re-prepare a prepared statement when a stored procedure used in top-level CALL is changed. mysql-test/t/ps_ddl1.test: Modifying stored procedure p1 no longer invalidates prepared statement "call p1" -- we can re-use the prepared statement without invalidation. mysql-test/t/sp-error.test: Use a constant for an error value. mysql-test/t/sp-lock.test: Add test coverage for Bug#30977. sql/lock.cc: Implement lock_routine_name() - a way to acquire an exclusive metadata lock (ex- name-lock) on stored procedure/function. sql/sp.cc: Change semantics of sp_cache_routine() -- now it has an option to make sure that the routine that is cached is up to date (has the latest sp cache version). Add sp_cache_invalidate() to sp_drop_routine(), where it was missing (a bug!). Acquire metadata locks for SP DDL (ALTER/CREATE/DROP). This is the core of the fix for Bug#30977. Since caching and cache invalidation scheme was changed, make sure we don't invalidate the SP cache in the middle of a stored routine execution. At the same time, make sure we don't access stale data due to lack of invalidation. For that, change ALTER FUNCTION/PROCEDURE to not use the cache, and SHOW PROCEDURE CODE/SHOW CREATE PROCEDURE/FUNCTION to always read an up to date version of the routine from the cache. sql/sp.h: Add a helper wrapper around sp_cache_routine(). sql/sp_cache.cc: Implement new sp_cache_version() and sp_cache_flush_obsolete(). Now we flush stale routines individually, rather than all at once. sql/sp_cache.h: Update signatures of sp_cache_version() and sp_cache_flush_obsolete(). sql/sp_head.cc: Add a default initialization of sp_head::m_sp_cache_version. Remove a redundant sp_head::create(). sql/sp_head.h: Add m_sp_cache_version to sp_head class - we now keep track of every routine in the stored procedure cache, rather than of the entire cache. sql/sql_base.cc: Implement prelocking for stored routines. Validate stored routines after they were locked. Flush obsolete routines upon next access, one by one, not all at once (Bug#41804). Style fixes. sql/sql_class.h: Rename a Open_table_context method. sql/sql_parse.cc: Make sure stored procedures DDL commits the active transaction (issues an implicit commit before and after). Remove sp_head::create(), a pure redundancy. Move the semantical check during alter routine inside sp_update_routine() code in order to: - avoid using SP cache during update, it may be obsolete. - speed up and simplify the update procedure. Remove sp_cache_flush_obsolete() calls, we no longer flush the entire cache, ever, stale routines are flushed before next use, one at a time. sql/sql_prepare.cc: Move routine metadata validation to open_and_process_routine(). Fix Bug#49972 (don't swap flags at reprepare). Reset Sroutine_hash_entries in reinit_stmt_before_use(). Remove SP cache invalidation, it's now done by open_tables(). sql/sql_show.cc: Fix a warning: remove an unused label. sql/sql_table.cc: Reset mdl_request.ticket for tickets acquired for routines inlined through a view, in CHECK TABLE statement, to satisfy an MDL assert. sql/sql_update.cc: Move the cleanup of "translation items" to close_tables_for_reopen(), since it's needed in all cases when we back off, not just the back-off in multi-update. This fixes a bug when the server would crash on attempt to back off when opening tables for a statement that uses information_schema tables.

# Reaping 'insert into t1 (a) values (f1())'...
Patch that changes approach to how we acquire metadata locks for DML statements and changes the way MDL locks are acquired/granted in contended case. Instead of backing-off when a lock conflict is encountered and waiting for it to go away before restarting open_tables() process we now wait for lock to be released without releasing any previously acquired locks. If conflicting lock goes away we resume opening tables. If waiting leads to a deadlock we try to resolve it by backing-off and restarting open_tables() immediately. As result both waiting for possibility to acquire and acquiring of a metadata lock now always happen within the same MDL API call. This has allowed to make release of a lock and granting it to the most appropriate pending request an atomic operation. Thanks to this it became possible to wake up during release of lock only those waiters which requests can be satisfied at the moment as well as wake up only one waiter in case when granting its request would prevent all other requests from being satisfied. This solves thundering herd problem which occured in cases when we were releasing some lock and woke up many waiters for SNRW or X locks (this was the issue in bug#52289 "performance regression for MyISAM in sysbench OLTP_RW test". This also allowed to implement more fair (FIFO) scheduling among waiters with the same priority. It also opens the door for introducing new types of requests for metadata locks such as low-prio SNRW lock which is necessary in order to support LOCK TABLES LOW_PRIORITY WRITE. Notice that after this sometimes can report ER_LOCK_DEADLOCK error in cases in which it has not happened before. Particularly we will always report this error if waiting for conflicting lock has happened in the middle of transaction and resulted in a deadlock. Before this patch the error was not reported if deadlock could have been resolved by backing off all metadata locks acquired by the current statement. mysql-test/r/mdl_sync.result: Added test coverage for some aspects of deadlock handling in metadata locking subsystem. Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/r/sp_sync.result: Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/suite/perfschema/r/dml_setup_instruments.result: Adjusted test results after renaming MDL_context:: m_waiting_for_lock rwlock to m_LOCK_waiting_for. mysql-test/suite/rpl/r/rpl_sp.result: Adjusted test case after implementing new approach to acquiring metadata locks in open_tables(). We no longer release all MDL locks acquired by statement before waiting for conflicting lock to go away. As result DROP FUNCTION statement has to wait for DML statement which managed to acquire metadata lock on function being dropped and now waits for other conflicting metadata lock to go away. mysql-test/suite/rpl/t/rpl_sp.test: Adjusted test case after implementing new approach to acquiring metadata locks in open_tables(). We no longer release all MDL locks acquired by statement before waiting for conflicting lock to go away. As result DROP FUNCTION statement has to wait for DML statement which managed to acquire metadata lock on function being dropped and now waits for other conflicting metadata lock to go away. mysql-test/t/mdl_sync.test: Added test coverage for some aspects of deadlock handling in metadata locking subsystem. Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/t/sp_sync.test: Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). sql/mdl.cc: Changed MDL subsystem to support new approach to acquring metadata locks in open tables and more fair and efficient scheduling of metadata locks. To implement this: - Made releasing of the lock and granting it to the most appropriate pending request atomic operation. As result it became possible to wake up only those waiters requests from which can be satisfied at the moment as well as wake-up only one waiter in case when granting its request would prevent all other requests from being satisfied. This solved thundering herd problem which occured in cases when we were releasing some lock and woke up many waiters for SNRW or X locks (this was the issue in Bug #52289 "performance regression for MyISAM in sysbench OLTP_RW test". To emphasize above changes wake_up_waiters() was renamed to MDL_context::reschedule_waiters(). - Changed code to add tickets for new requests to the back of waiters queue and to select tickets to be satisfied from the head of the queue if possible (this makes scheduling of requests with the same priority fair). To be able to do this efficiently we now use for waiting and granted queues version of I_P_List class which provides fast push_back() method. - Members and methods of MDL_context related to sending and waiting for signal were moved to separate MDL_wait class. - Since in order to avoid race conditions we must grant the lock only to the context which was not chosen as a victim of deadlock, killed or aborted due to timeout MDL_wait::set_status() (former awake()) was changed not to send signal if signal slot is already occupied and to indicate this fact through its return value. As another consequence MDL_wait::timed_wait() method was changed to handle timeout (optionally) and abort due to kill as signals which make signal slot occupied. - Renamed MDL_context::acquire_lock_impl() to acquire_lock(). Changed it to be able correctly process requests for shared locks when there are open HANDLERs, made this method more optimized for acquisition of shared locks. As part of this change moved code common between try_acquire_lock() and acquire_lock() to new try_acquire_lock_impl() method. Also adjusted acquire_lock()'s code to take into account the fact that in cases when lock is granted as result of MDL_context::reschedule_waiters() call (i.e. when it is granted after waiting for lock conflict to go away) updating MDL_lock state is responsibility of the thread calling reschedule_waiters(). - Changed MDL_context::find_deadlock() to send VICTIM signal even if victim is the context which has initiated deadlock detection. This is required in order to avoid races in cases when the same context simultaneously is chosen as a victim and its request for lock is satisfied. As result return value of this method became unnecessary and it was changed to return void. Adjusted MDL_lock::find_deadlock() method to take into account that now there can be a discrepancy between MDL_context::m_waiting_for value being set and real state of the ticket this member points to. - Renamed MDL_context::m_waiting_for_lock to m_LOCK_waiting_for and MDL_context::stop_waiting() to done_waiting_for(). - Finally, removed MDL_context::wait_for_lock() method. sql/mdl.h: Changed MDL subsystem to support new approach to acquring metadata locks in open tables and more fair and efficient scheduling of metadata locks. To implement this: - Members and methods of MDL_context related to sending and waiting for signal were moved to separate MDL_wait class. - Since now in order to avoid race conditions we must grant the lock only to the context which was not chosen as a victim of deadlock, killed or aborted due to timeout MDL_wait::set_status (former awake()) was changed not to send signal if signal slot is already occupied and to indicate this fact through its return value. Also NORMAL_WAKE_UP signal became GRANTED, and timeouts and aborts due to kill became full blown signals rather than simple return values. - MDL_wait::timed_wait() now takes extra parameter that indicates whether signal should be set if timeout is reached. - Enabled fast push_back() operation in MDL_context::m_tickets list to make move_ticket_after_trans_sentinel() method more efficient. - Removed MDL_context::wait_for_lock() method. - Renamed MDL_context::m_waiting_for_lock to m_LOCK_waiting_for and MDL_context::stop_waiting() to done_waiting_for(). - MDL_context::acquire_lock_impl() became acquire_lock(). - Introduced MDL_context::try_acquire_lock_impl() as a place for code shared by try_acquire_lock and acquire_lock(). - Due to fact that now VICTIM signal is sent even if victim is the context which has initiated deadlock detection find_deadlock() no longer needs a return value. sql/sql_base.cc: Implemented new approach to acquiring metadata locks in open_tables(). We no longer perform back-off when conflicting metadata lock is encountered. Instead we wait for this lock to go away while holding all locks which were acquired so far. Back-off is only used in situation when further waiting will cause a deadlock which could be avoided by performing back-off and restarting open_tables() process. Absence of waiting between back-off and restart of acquiring metadata locks can't lead to livelocks as MDL subsystem was changed to make release of lock and granting it to waiting lock an atomic action, so back-off will automatically give way to other participants of deadlock loop. Accordingly: - open_table_get_mdl_lock() and open_and_process_routine() were changed to wait for conflicting metadata lock to go away without back-off. Only if such wait leads to a deadlock back-off is requested. As part of this change new error handler class was introduced which converts, if possible, ER_LOCK_DEADLOCK error to a request for back-off and re-start of open_tables() process. - Open_table_context::recover_from_failed_open() was changed not to wait in case of metadata lock conflict. Instead we immediately proceed to re-acquiring locks. - Open_table_context::request_backoff_action() now always emits error if back-off is requested in the middle of transaction as we can't be sure that releasing lock which were acquired only by current statement will resolve a deadlock. Before this patch such situations were successfully detected thanks to the fact that we called MDL_context::wait_for_lock() method in recover_from_failed_open(). - In order to avoid deadlocks open_tables() code was adjusted to flush open HANDLERs for which there are pending requests for X locks before restarting the process of acquiring metadata locks. - Changed close_tables_for_reopen() not to reset MDL_request for tables belonging to the tail of prelocking list. It is no longer necessary as these MDL_request objects won't be used for any waiting. - Adjusted comment in tdc_wait_for_old_version() to avoid mentioning removed MDL_context::wait_for_lock() method. sql/sql_base.h: As we no longer wait for conflicting metadata lock away in Open_table_context::recover_from_failed_open() method, Open_table_context::OT_WAIT_MDL_LOCK action was renamed to OT_MDL_CONFLICT. Also Open_table_context::m_failed_mdl_request became unnecessary and was removed. sql/sql_plist.h: Extended I_P_List template to support efficient push_back() operation if it is parameterized with an appropriate policy class. sql/sql_show.cc: Adjusted code after removal of MDL_context::wait_for_lock() method. Now if one needs to acquire metadata lock with waiting one has to use a variant of MDL_context::acquire_lock() method.

As part of this change new error handler class was introduced which converts, if possible, ER_LOCK_DEADLOCK error to a request for back-off and re-start of open_tables() process. - Open_table_context::recover_from_failed_open() was changed not to wait in case of metadata lock conflict. Instead we immediately proceed to re-acquiring locks. - Open_table_context::request_backoff_action() now always emits error if back-off is requested in the middle of transaction as we can't be sure that releasing lock which were acquired only by current statement will resolve a deadlock. Before this patch such situations were successfully detected thanks to the fact that we called MDL_context::wait_for_lock() method in recover_from_failed_open(). - In order to avoid deadlocks open_tables() code was adjusted to flush open HANDLERs for which there are pending requests for X locks before restarting the process of acquiring metadata locks. - Changed close_tables_for_reopen() not to reset MDL_request for tables belonging to the tail of prelocking list. It is no longer necessary as these MDL_request objects won't be used for any waiting. - Adjusted comment in tdc_wait_for_old_version() to avoid mentioning removed MDL_context::wait_for_lock() method. sql/sql_base.h: As we no longer wait for conflicting metadata lock away in Open_table_context::recover_from_failed_open() method, Open_table_context::OT_WAIT_MDL_LOCK action was renamed to OT_MDL_CONFLICT. Also Open_table_context::m_failed_mdl_request became unnecessary and was removed. sql/sql_plist.h: Extended I_P_List template to support efficient push_back() operation if it is parameterized with an appropriate policy class. sql/sql_show.cc: Adjusted code after removal of MDL_context::wait_for_lock() method. Now if one needs to acquire metadata lock with waiting one has to use a variant of MDL_context::acquire_lock() method.

Apply and review: 3655 Jon Olav Hauglid 2009-10-19 Bug #30977 Concurrent statement using stored function and DROP FUNCTION breaks SBR Bug #48246 assert in close_thread_table Implement a fix for: Bug #41804 purge stored procedure cache causes mysterious hang for many minutes Bug #49972 Crash in prepared statements The problem was that concurrent execution of DML statements that use stored functions and DDL statements that drop/modify the same function might result in incorrect binary log in statement (and mixed) mode and therefore break replication. This patch fixes the problem by introducing metadata locking for stored procedures and functions. This is similar to what is done in Bug#25144 for views. Procedures and functions now are locked using metadata locks until the transaction is either committed or rolled back. This prevents other statements from modifying the procedure/function while it is being executed. This provides commit ordering - guaranteeing serializability across multiple transactions and thus fixes the reported binlog problem. Note that we do not take locks for top-level CALLs. This means that procedures called directly are not protected from changes by simultaneous DDL operations so they are executed at the state they had at the time of the CALL. By not taking locks for top-level CALLs, we still allow transactions to be started inside procedures. This patch also changes stored procedure cache invalidation. Upon a change of cache version, we no longer invalidate the entire cache, but only those routines which we use, only when a statement is executed that uses them. This patch also changes the logic of prepared statement validation. A stored procedure used by a prepared statement is now validated only once a metadata lock has been acquired. A version mismatch causes a flush of the obsolete routine from the cache and statement reprepare. Incompatible changes: 1) ER_LOCK_DEADLOCK is reported for a transaction trying to access a procedure/function that is locked by a DDL operation in another connection. 2) Procedure/function DDL operations are now prohibited in LOCK TABLES mode as exclusive locks must be taken all at once and LOCK TABLES provides no way to specifiy procedures/functions to be locked. Test cases have been added to sp-lock.test and rpl_sp.test. Work on this bug has very much been a team effort and this patch includes and is based on contributions from Davi Arnaut, Dmitry Lenev, Magne Mæhre and Konstantin Osipov. mysql-test/r/ps_ddl.result: Update results (Bug#30977). mysql-test/r/ps_ddl1.result: Update results (Bug#30977). mysql-test/r/sp-error.result: Update results (Bug#30977). mysql-test/r/sp-lock.result: Update results (Bug#30977). mysql-test/suite/rpl/r/rpl_sp.result: Update results (Bug#30977). mysql-test/suite/rpl/t/rpl_sp.test: Add a test case for Bug#30977. mysql-test/t/ps_ddl.test: Update comments.

This fixes a bug when the server would crash on attempt to back off when opening tables for a statement that uses information_schema tables.

a
Patch that changes approach to how we acquire metadata locks for DML statements and changes the way MDL locks are acquired/granted in contended case. Instead of backing-off when a lock conflict is encountered and waiting for it to go away before restarting open_tables() process we now wait for lock to be released without releasing any previously acquired locks. If conflicting lock goes away we resume opening tables. If waiting leads to a deadlock we try to resolve it by backing-off and restarting open_tables() immediately. As result both waiting for possibility to acquire and acquiring of a metadata lock now always happen within the same MDL API call. This has allowed to make release of a lock and granting it to the most appropriate pending request an atomic operation. Thanks to this it became possible to wake up during release of lock only those waiters which requests can be satisfied at the moment as well as wake up only one waiter in case when granting its request would prevent all other requests from being satisfied. This solves thundering herd problem which occured in cases when we were releasing some lock and woke up many waiters for SNRW or X locks (this was the issue in bug#52289 "performance regression for MyISAM in sysbench OLTP_RW test". This also allowed to implement more fair (FIFO) scheduling among waiters with the same priority. It also opens the door for introducing new types of requests for metadata locks such as low-prio SNRW lock which is necessary in order to support LOCK TABLES LOW_PRIORITY WRITE. Notice that after this sometimes can report ER_LOCK_DEADLOCK error in cases in which it has not happened before. Particularly we will always report this error if waiting for conflicting lock has happened in the middle of transaction and resulted in a deadlock. Before this patch the error was not reported if deadlock could have been resolved by backing off all metadata locks acquired by the current statement. mysql-test/r/mdl_sync.result: Added test coverage for some aspects of deadlock handling in metadata locking subsystem. Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/r/sp_sync.result: Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/suite/perfschema/r/dml_setup_instruments.result: Adjusted test results after renaming MDL_context:: m_waiting_for_lock rwlock to m_LOCK_waiting_for. mysql-test/suite/rpl/r/rpl_sp.result: Adjusted test case after implementing new approach to acquiring metadata locks in open_tables(). We no longer release all MDL locks acquired by statement before waiting for conflicting lock to go away. As result DROP FUNCTION statement has to wait for DML statement which managed to acquire metadata lock on function being dropped and now waits for other conflicting metadata lock to go away. mysql-test/suite/rpl/t/rpl_sp.test: Adjusted test case after implementing new approach to acquiring metadata locks in open_tables(). We no longer release all MDL locks acquired by statement before waiting for conflicting lock to go away. As result DROP FUNCTION statement has to wait for DML statement which managed to acquire metadata lock on function being dropped and now waits for other conflicting metadata lock to go away. mysql-test/t/mdl_sync.test: Added test coverage for some aspects of deadlock handling in metadata locking subsystem. Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). mysql-test/t/sp_sync.test: Adjusted test case after removing back-off in general case when conflicting metadata lock is encountered during open_tables() (now this happens only if waiting for conflicting lock to go away leads to a deadlock). sql/mdl.cc: Changed MDL subsystem to support new approach to acquring metadata locks in open tables and more fair and efficient scheduling of metadata locks. To implement this: - Made releasing of the lock and granting it to the most appropriate pending request atomic operation. As result it became possible to wake up only those waiters requests from which can be satisfied at the moment as well as wake-up only one waiter in case when granting its request would prevent all other requests from being satisfied. This solved thundering herd problem which occured in cases when we were releasing some lock and woke up many waiters for SNRW or X locks (this was the issue in Bug #52289 "performance regression for MyISAM in sysbench OLTP_RW test". To emphasize above changes wake_up_waiters() was renamed to MDL_context::reschedule_waiters(). - Changed code to add tickets for new requests to the back of waiters queue and to select tickets to be satisfied from the head of the queue if possible (this makes scheduling of requests with the same priority fair). To be able to do this efficiently we now use for waiting and granted queues version of I_P_List class which provides fast push_back() method. - Members and methods of MDL_context related to sending and waiting for signal were moved to separate MDL_wait class. - Since in order to avoid race conditions we must grant the lock only to the context which was not chosen as a victim of deadlock, killed or aborted due to timeout MDL_wait::set_status() (former awake()) was changed not to send signal if signal slot is already occupied and to indicate this fact through its return value. As another consequence MDL_wait::timed_wait() method was changed to handle timeout (optionally) and abort due to kill as signals which make signal slot occupied. - Renamed MDL_context::acquire_lock_impl() to acquire_lock(). Changed it to be able correctly process requests for shared locks when there are open HANDLERs, made this method more optimized for acquisition of shared locks. As part of this change moved code common between try_acquire_lock() and acquire_lock() to new try_acquire_lock_impl() method. Also adjusted acquire_lock()'s code to take into account the fact that in cases when lock is granted as result of MDL_context::reschedule_waiters() call (i.e. when it is granted after waiting for lock conflict to go away) updating MDL_lock state is responsibility of the thread calling reschedule_waiters(). - Changed MDL_context::find_deadlock() to send VICTIM signal even if victim is the context which has initiated deadlock detection. This is required in order to avoid races in cases when the same context simultaneously is chosen as a victim and its request for lock is satisfied. As result return value of this method became unnecessary and it was changed to return void. Adjusted MDL_lock::find_deadlock() method to take into account that now there can be a discrepancy between MDL_context::m_waiting_for value being set and real state of the ticket this member points to. - Renamed MDL_context::m_waiting_for_lock to m_LOCK_waiting_for and MDL_context::stop_waiting() to done_waiting_for(). - Finally, removed MDL_context::wait_for_lock() method. sql/mdl.h: Changed MDL subsystem to support new approach to acquring metadata locks in open tables and more fair and efficient scheduling of metadata locks. To implement this: - Members and methods of MDL_context related to sending and waiting for signal were moved to separate MDL_wait class. - Since now in order to avoid race conditions we must grant the lock only to the context which was not chosen as a victim of deadlock, killed or aborted due to timeout MDL_wait::set_status (former awake()) was changed not to send signal if signal slot is already occupied and to indicate this fact through its return value. Also NORMAL_WAKE_UP signal became GRANTED, and timeouts and aborts due to kill became full blown signals rather than simple return values. - MDL_wait::timed_wait() now takes extra parameter that indicates whether signal should be set if timeout is reached. - Enabled fast push_back() operation in MDL_context::m_tickets list to make move_ticket_after_trans_sentinel() method more efficient. - Removed MDL_context::wait_for_lock() method. - Renamed MDL_context::m_waiting_for_lock to m_LOCK_waiting_for and MDL_context::stop_waiting() to done_waiting_for(). - MDL_context::acquire_lock_impl() became acquire_lock(). - Introduced MDL_context::try_acquire_lock_impl() as a place for code shared by try_acquire_lock and acquire_lock(). - Due to fact that now VICTIM signal is sent even if victim is the context which has initiated deadlock detection find_deadlock() no longer needs a return value. sql/sql_base.cc: Implemented new approach to acquiring metadata locks in open_tables(). We no longer perform back-off when conflicting metadata lock is encountered. Instead we wait for this lock to go away while holding all locks which were acquired so far. Back-off is only used in situation when further waiting will cause a deadlock which could be avoided by performing back-off and restarting open_tables() process. Absence of waiting between back-off and restart of acquiring metadata locks can't lead to livelocks as MDL subsystem was changed to make release of lock and granting it to waiting lock an atomic action, so back-off will automatically give way to other participants of deadlock loop. Accordingly: - open_table_get_mdl_lock() and open_and_process_routine() were changed to wait for conflicting metadata lock to go away without back-off. Only if such wait leads to a deadlock back-off is requested. As part of this change new error handler class was introduced which converts, if possible, ER_LOCK_DEADLOCK error to a request for back-off and re-start of open_tables() process. - Open_table_context::recover_from_failed_open() was changed not to wait in case of metadata lock conflict. Instead we immediately proceed to re-acquiring locks. - Open_table_context::request_backoff_action() now always emits error if back-off is requested in the middle of transaction as we can't be sure that releasing lock which were acquired only by current statement will resolve a deadlock. Before this patch such situations were successfully detected thanks to the fact that we called MDL_context::wait_for_lock() method in recover_from_failed_open(). - In order to avoid deadlocks open_tables() code was adjusted to flush open HANDLERs for which there are pending requests for X locks before restarting the process of acquiring metadata locks. - Changed close_tables_for_reopen() not to reset MDL_request for tables belonging to the tail of prelocking list. It is no longer necessary as these MDL_request objects won't be used for any waiting. - Adjusted comment in tdc_wait_for_old_version() to avoid mentioning removed MDL_context::wait_for_lock() method. sql/sql_base.h: As we no longer wait for conflicting metadata lock away in Open_table_context::recover_from_failed_open() method, Open_table_context::OT_WAIT_MDL_LOCK action was renamed to OT_MDL_CONFLICT. Also Open_table_context::m_failed_mdl_request became unnecessary and was removed. sql/sql_plist.h: Extended I_P_List template to support efficient push_back() operation if it is parameterized with an appropriate policy class. sql/sql_show.cc: Adjusted code after removal of MDL_context::wait_for_lock() method. Now if one needs to acquire metadata lock with waiting one has to use a variant of MDL_context::acquire_lock() method.

Apply and review: 3655 Jon Olav Hauglid 2009-10-19 Bug #30977 Concurrent statement using stored function and DROP FUNCTION breaks SBR Bug #48246 assert in close_thread_table Implement a fix for: Bug #41804 purge stored procedure cache causes mysterious hang for many minutes Bug #49972 Crash in prepared statements The problem was that concurrent execution of DML statements that use stored functions and DDL statements that drop/modify the same function might result in incorrect binary log in statement (and mixed) mode and therefore break replication. This patch fixes the problem by introducing metadata locking for stored procedures and functions. This is similar to what is done in Bug#25144 for views. Procedures and functions now are locked using metadata locks until the transaction is either committed or rolled back. This prevents other statements from modifying the procedure/function while it is being executed. This provides commit ordering - guaranteeing serializability across multiple transactions and thus fixes the reported binlog problem. Note that we do not take locks for top-level CALLs. This means that procedures called directly are not protected from changes by simultaneous DDL operations so they are executed at the state they had at the time of the CALL. By not taking locks for top-level CALLs, we still allow transactions to be started inside procedures. This patch also changes stored procedure cache invalidation. Upon a change of cache version, we no longer invalidate the entire cache, but only those routines which we use, only when a statement is executed that uses them. This patch also changes the logic of prepared statement validation. A stored procedure used by a prepared statement is now validated only once a metadata lock has been acquired. A version mismatch causes a flush of the obsolete routine from the cache and statement reprepare. Incompatible changes: 1) ER_LOCK_DEADLOCK is reported for a transaction trying to access a procedure/function that is locked by a DDL operation in another connection. 2) Procedure/function DDL operations are now prohibited in LOCK TABLES mode as exclusive locks must be taken all at once and LOCK TABLES provides no way to specifiy procedures/functions to be locked. Test cases have been added to sp-lock.test and rpl_sp.test. Work on this bug has very much been a team effort and this patch includes and is based on contributions from Davi Arnaut, Dmitry Lenev, Magne Mæhre and Konstantin Osipov. mysql-test/r/ps_ddl.result: Update results (Bug#30977). mysql-test/r/ps_ddl1.result: Update results (Bug#30977). mysql-test/r/sp-error.result: Update results (Bug#30977). mysql-test/r/sp-lock.result: Update results (Bug#30977). mysql-test/suite/rpl/r/rpl_sp.result: Update results (Bug#30977). mysql-test/suite/rpl/t/rpl_sp.test: Add a test case for Bug#30977. mysql-test/t/ps_ddl.test: Update comments. We no longer re-prepare a prepared statement when a stored procedure used in top-level CALL is changed. mysql-test/t/ps_ddl1.test: Modifying stored procedure p1 no longer invalidates prepared statement "call p1" -- we can re-use the prepared statement without invalidation. mysql-test/t/sp-error.test: Use a constant for an error value. mysql-test/t/sp-lock.test: Add test coverage for Bug#30977. sql/lock.cc: Implement lock_routine_name() - a way to acquire an exclusive metadata lock (ex- name-lock) on stored procedure/function. sql/sp.cc: Change semantics of sp_cache_routine() -- now it has an option to make sure that the routine that is cached is up to date (has the latest sp cache version). Add sp_cache_invalidate() to sp_drop_routine(), where it was missing (a bug!). Acquire metadata locks for SP DDL (ALTER/CREATE/DROP). This is the core of the fix for Bug#30977. Since caching and cache invalidation scheme was changed, make sure we don't invalidate the SP cache in the middle of a stored routine execution. At the same time, make sure we don't access stale data due to lack of invalidation. For that, change ALTER FUNCTION/PROCEDURE to not use the cache, and SHOW PROCEDURE CODE/SHOW CREATE PROCEDURE/FUNCTION to always read an up to date version of the routine from the cache. sql/sp.h: Add a helper wrapper around sp_cache_routine(). sql/sp_cache.cc: Implement new sp_cache_version() and sp_cache_flush_obsolete(). Now we flush stale routines individually, rather than all at once. sql/sp_cache.h: Update signatures of sp_cache_version() and sp_cache_flush_obsolete(). sql/sp_head.cc: Add a default initialization of sp_head::m_sp_cache_version. Remove a redundant sp_head::create(). sql/sp_head.h: Add m_sp_cache_version to sp_head class - we now keep track of every routine in the stored procedure cache, rather than of the entire cache. sql/sql_base.cc: Implement prelocking for stored routines. Validate stored routines after they were locked. Flush obsolete routines upon next access, one by one, not all at once (Bug#41804). Style fixes. sql/sql_class.h: Rename a Open_table_context method. sql/sql_parse.cc: Make sure stored procedures DDL commits the active transaction (issues an implicit commit before and after). Remove sp_head::create(), a pure redundancy. Move the semantical check during alter routine inside sp_update_routine() code in order to: - avoid using SP cache during update, it may be obsolete. - speed up and simplify the update procedure. Remove sp_cache_flush_obsolete() calls, we no longer flush the entire cache, ever, stale routines are flushed before next use, one at a time. sql/sql_prepare.cc: Move routine metadata validation to open_and_process_routine(). Fix Bug#49972 (don't swap flags at reprepare). Reset Sroutine_hash_entries in reinit_stmt_before_use(). Remove SP cache invalidation, it's now done by open_tables(). sql/sql_show.cc: Fix a warning: remove an unused label. sql/sql_table.cc: Reset mdl_request.ticket for tickets acquired for routines inlined through a view, in CHECK TABLE statement, to satisfy an MDL assert. sql/sql_update.cc: Move the cleanup of "translation items" to close_tables_for_reopen(), since it's needed in all cases when we back off, not just the back-off in multi-update. This fixes a bug when the server would crash on attempt to back off when opening tables for a statement that uses information_schema tables.
