BUG#39934: Slave stops for engine that only support row-based logging
General overview: The logic for switching to row format when binlog_format=MIXED had numerous flaws. The underlying problem was the lack of a consistent architecture. General purpose of this changeset: This changeset introduces an architecture for switching to row format when binlog_format=MIXED. It enforces the architecture where it has to. It leaves some bugs to be fixed later. It adds extensive tests to verify that unsafe statements work as expected and that appropriate errors are produced by problems with the selection of binlog format. It was not practical to split this into smaller pieces of work. Problem 1: To determine the logging mode, the code has to take several parameters into account (namely: (1) the value of binlog_format; (2) the capabilities of the engines; (3) the type of the current statement: normal, unsafe, or row injection). These parameters may conflict in several ways, namely: - binlog_format=STATEMENT for a row injection - binlog_format=STATEMENT for an unsafe statement - binlog_format=STATEMENT for an engine only supporting row logging - binlog_format=ROW for an engine only supporting statement logging - statement is unsafe and engine does not support row logging - row injection in a table that does not support statement logging - statement modifies one table that does not support row logging and one that does not support statement logging Several of these conflicts were not detected, or were detected with an inappropriate error message. The problem of BUG#39934 was that no appropriate error message was written for the case when an engine only supporting row logging executed a row injection with binlog_format=ROW. However, all above cases must be handled. Fix 1: Introduce new error codes (sql/share/errmsg.txt). Ensure that all conditions are detected and handled in decide_logging_format() Problem 2: The binlog format shall be determined once per statement, in decide_logging_format(). It shall not be changed before or after that. Before decide_logging_format() is called, all information necessary to determine the logging format must be available. This principle ensures that all unsafe statements are handled in a consistent way. However, this principle is not followed: thd->set_current_stmt_binlog_row_based_if_mixed() is called in several places, including from code executing UPDATE..LIMIT, INSERT..SELECT..LIMIT, DELETE..LIMIT, INSERT DELAYED, and SET @@binlog_format. After Problem 1 was fixed, that caused inconsistencies where these unsafe statements would not print the appropriate warnings or errors for some of the conflicts. Fix 2: Remove calls to THD::set_current_stmt_binlog_row_based_if_mixed() from code executed after decide_logging_format(). Compensate by calling the set_current_stmt_unsafe() at parse time. This way, all unsafe statements are detected by decide_logging_format(). Problem 3: INSERT DELAYED is not unsafe: it is logged in statement format even if binlog_format=MIXED, and no warning is printed even if binlog_format=STATEMENT. This is BUG#45825. Fix 3: Made INSERT DELAYED set itself to unsafe at parse time. This allows decide_logging_format() to detect that a warning should be printed or the binlog_format changed. Problem 4: LIMIT clause were not marked as unsafe when executed inside stored functions/triggers/views/prepared statements. This is BUG#45785. Fix 4: Make statements containing the LIMIT clause marked as unsafe at parse time, instead of at execution time. This allows propagating unsafe-ness to the view. mysql-test/extra/rpl_tests/create_recursive_construct.inc: Added auxiliary file used by binlog_unsafe.test to create and execute recursive constructs (functions/procedures/triggers/views/prepared statements). mysql-test/extra/rpl_tests/rpl_foreign_key.test: removed unnecessary set @@session.binlog_format mysql-test/extra/rpl_tests/rpl_insert_delayed.test: Filter out table id from table map events in binlog listing. Got rid of $binlog_format_statement. mysql-test/extra/rpl_tests/rpl_ndb_apply_status.test: disable warnings around call to unsafe procedure mysql-test/include/rpl_udf.inc: Disabled warnings for code that generates warnings for some binlog formats. That would otherwise cause inconsistencies in the result file. mysql-test/r/mysqldump.result: Views are now unsafe if they contain a LIMIT clause. That fixed BUG#45831. Due to BUG#45832, a warning is printed for the CREATE VIEW statement. mysql-test/r/sp_trans.result: Unsafe statements in stored procedures did not give a warning if binlog_format=statement. This is BUG#45824. Now they do, so this result file gets a new warning. mysql-test/suite/binlog/r/binlog_multi_engine.result: Error message changed. mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result: INSERT DELAYED didn't generate a warning when binlog_format=STATEMENT. That was BUG#45825. Now there is a warning, so result file needs to be updated. mysql-test/suite/binlog/r/binlog_stm_ps.result: Changed error message. mysql-test/suite/binlog/r/binlog_unsafe.result: updated result file: - error message changed - added test for most combinations of unsafe constructs invoked from recursive constructs - INSERT DELAYED now gives a warning (because BUG#45826 is fixed) - INSERT..SELECT..LIMIT now gives a warning from inside recursive constructs (because BUG#45785 was fixed) - When a recursive construct (e.g., stored proc or function) contains more than one statement, at least one of which is unsafe, then all statements in the recursive construct give warnings. This is a new bug introduced by this changeset. It will be addressed in a post-push fix. mysql-test/suite/binlog/t/binlog_innodb.test: Changed error code for innodb updates with READ COMMITTED or READ UNCOMMITTED transaction isolation level and binlog_format=statement. mysql-test/suite/binlog/t/binlog_multi_engine.test: The error code has changed for statements where more than one engine is involved and one of them is self-logging. mysql-test/suite/binlog/t/binlog_unsafe-master.opt: Since binlog_unsafe now tests unsafe-ness of UDF's, we need an extra flag in the .opt file. mysql-test/suite/binlog/t/binlog_unsafe.test: - Clarified comment. - Rewrote first part of test. Now it tests not only unsafe variables and functions, but also unsafe-ness due to INSERT..SELECT..LIMIT, INSERT DELAYED, insert into two autoinc columns, use of UDF's, and access to log tables in the mysql database. Also, in addition to functions, procedures, triggers, and prepared statements, it now also tests views; and it constructs recursive calls in two levels by combining these recursive constructs. Part of the logic is in extra/rpl_tests/create_recursive_construct.inc. - added tests for all special system variables that should not be unsafe. - added specific tests for BUG#45785 and BUG#45825 mysql-test/suite/rpl/r/rpl_events.result: updated result file mysql-test/suite/rpl/r/rpl_extraColmaster_innodb.result: updated result file mysql-test/suite/rpl/r/rpl_extraColmaster_myisam.result: updated result file mysql-test/suite/rpl/r/rpl_foreign_key_innodb.result: updated result file mysql-test/suite/rpl/r/rpl_idempotency.result: updated result file mysql-test/suite/rpl/r/rpl_mix_found_rows.result: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file equals the second half of the old rpl_found_rows.result, with the following modifications: - minor formatting changes - additional initialization mysql-test/suite/rpl/r/rpl_mix_insert_delayed.result: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_rbr_to_sbr.result: updated result file mysql-test/suite/rpl/r/rpl_row_idempotency.result: Moved the second half of rpl_idempotency.test, which only executed in row mode, to rpl_row_idempotency.test. This is the new result file. mysql-test/suite/rpl/r/rpl_row_insert_delayed.result: Got rid of unnecessary explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_stm_found_rows.result: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in this file: - minor formatting changes - warning is now issued for unsafe statements inside procedures (since BUG#45824 is fixed) - second half of file is moved to rpl_mix_found_rows.result mysql-test/suite/rpl/r/rpl_stm_insert_delayed.result: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/r/rpl_stm_loadfile.result: error message changed mysql-test/suite/rpl/r/rpl_temporary_errors.result: updated result file mysql-test/suite/rpl/r/rpl_udf.result: Remove explicit set of binlog format (and triplicate test execution) and rely on test system executing the test in all binlog formats. mysql-test/suite/rpl/t/rpl_bug31076.test: Test is only valid in mixed or row mode since it generates row events. mysql-test/suite/rpl/t/rpl_events.test: Removed explicit set of binlog_format and removed duplicate testing. Instead, we rely on the test system to try all binlog formats. mysql-test/suite/rpl/t/rpl_extraColmaster_innodb.test: Removed triplicate testing and instead relying on test system. Test is only relevant for row format since statement-based replication cannot handle extra columns on master. mysql-test/suite/rpl/t/rpl_extraColmaster_myisam.test: Removed triplicate testing and instead relying on test system. Test is only relevant for row format since statement-based replication cannot handle extra columns on master. mysql-test/suite/rpl/t/rpl_idempotency-slave.opt: Removed .opt file to avoid server restarts. mysql-test/suite/rpl/t/rpl_idempotency.test: - Moved out row-only tests to a new test file, rpl_row_idempotency.test. rpl_idempotency now only contains tests that execute in all binlog_formats. - While I was here, also removed .opt file to avoid server restarts. The slave_exec_mode is now set inside the test instead. mysql-test/suite/rpl/t/rpl_mix_found_rows.test: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file contains the second half of the original rpl_found_rows.test with the follwing changes: - initialization - removed SET_BINLOG_FORMAT and added have_binlog_format_mixed.inc - minor formatting changes mysql-test/suite/rpl/t/rpl_mix_insert_delayed.test: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/t/rpl_rbr_to_sbr.test: Test cannot execute in statement mode, since we no longer switch to row format when binlog_format=statement. Enforced mixed mode throughout the test. mysql-test/suite/rpl/t/rpl_row_idempotency.test: Moved the second half of rpl_idempotency.test, which only executed in row mode, to this new file. We now rely on the test system to set binlog format. mysql-test/suite/rpl/t/rpl_row_insert_delayed.test: - Got rid of unnecessary explicit setting of binlog format. - extra/rpl_tests/rpl_insert_delayed.test does not need the $binlog_format_statement variable any more, so that was removed. mysql-test/suite/rpl/t/rpl_slave_skip.test: The test switches binlog_format internally and master generates both row and statement events. Hence, the slave must be able to log in both statement and row format. Hence test was changed to only execute in mixed mode. mysql-test/suite/rpl/t/rpl_stm_found_rows.test: Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in this file: - minor formatting changes - added have_binlog_format_statement and removed SET BINLOG_FORMAT. - second half of file is moved to rpl_mix_found_rows.test - added cleanup code mysql-test/suite/rpl/t/rpl_stm_insert_delayed.test: Moved out code operating in mixed mode from rpl_stm_insert_delayed (into rpl_mix_insert_delayed) and got rid of explicit setting of binlog format. mysql-test/suite/rpl/t/rpl_switch_stm_row_mixed.test: The test switches binlog_format internally and master generates both row and statement events. Hence, the slave must be able to log in both statement and row format. Hence test was changed to only execute in mixed mode on slave. mysql-test/suite/rpl/t/rpl_temporary_errors.test: Removed explicit set of binlog format. Instead, the test now only executes in row mode. mysql-test/suite/rpl/t/rpl_udf.test: Remove explicit set of binlog format (and triplicate test execution) and rely on test system executing the test in all binlog formats. mysql-test/suite/rpl_ndb/combinations: Added combinations file for rpl_ndb. mysql-test/suite/rpl_ndb/r/rpl_ndb_binlog_format_errors.result: new result file mysql-test/suite/rpl_ndb/r/rpl_ndb_circular_simplex.result: updated result file mysql-test/suite/rpl_ndb/t/rpl_ndb_2innodb.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_2myisam.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_basic.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors-master.opt: new option file mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors-slave.opt: new option file mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors.test: New test case to verify all errors and warnings generated by decide_logging_format. mysql-test/suite/rpl_ndb/t/rpl_ndb_blob.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_blob2.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_circular.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_circular_simplex.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. While I was here, also made the test clean up after itself. mysql-test/suite/rpl_ndb/t/rpl_ndb_commit_afterflush.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_ctype_ucs2_def.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_delete_nowhere.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_do_db.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_do_table.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_func003.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_innodb_trans.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_insert_ignore.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_mixed_engines_transactions.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_multi_update3.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_rep_ignore.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_row_001.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_sp003.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_sp006.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/suite/rpl_ndb/t/rpl_ndb_trig004.test: The test needs slave to be able to switch to row mode, so the test was changed to only execute in mixed and row mode. mysql-test/t/partition_innodb_stmt.test: Changed error code for innodb updates with READ COMMITTED or READ UNCOMMITTED transaction isolation level and binlog_format=statement. sql/event_db_repository.cc: Use member function to read current_stmt_binlog_row_based. sql/events.cc: Use member function to read current_stmt_binlog_row_based. sql/ha_ndbcluster_binlog.cc: reset_current_stmt_binlog_row_based() is not a no-op for the ndb_binlog thread any more. Instead, the ndb_binlog thread now forces row mode both initially and just after calling mysql_parse. (mysql_parse() is the only place where reset_current_stmt_binlog_row_based() may be called from the ndb_binlog thread, so these are the only two places that need to change.) sql/ha_partition.cc: Use member function to read current_stmt_binlog_row_based. sql/handler.cc: Use member function to read current_stmt_binlog_row_based. sql/item_create.cc: Added DBUG_ENTER to some functions, to be able to trace when set_stmt_unsafe is called. sql/log.cc: Use member function to read current_stmt_binlog_row_based. sql/log_event.cc: - Moved logic for changing to row format out of do_apply_event (and into decide_logging_format). - Added @todo comment for post-push cleanup. sql/log_event_old.cc: Move logic for changing to row format out of do_apply_event (and into decide_logging_format). sql/mysql_priv.h: Make decide_logging_format() a member of the THD class, for two reasons: - It is natural from an object-oriented perspective. - decide_logging_format() needs to access private members of THD (specifically, the new binlog_warning_flags field). sql/rpl_injector.cc: Removed call to set_current_stmt_binlog_row_based(). From now on, only decide_logging_fromat is allowed to modify current_stmt_binlog_row_based. This call is from the ndb_binlog thread, mostly executing code in ha_ndbcluster_binlog.cc. This call can be safely removed, because: - current_stmt_binlog_row_based is initialized for the ndb_binlog thread's THD object when the THD object is created. So we're not going to read uninitialized memory. - The behavior of ndb_binlog thread does not use the state of the current_stmt_binlog_row_based. It is conceivable that the ndb_binlog thread would rely on the current_stmt_binlog_format in two situations: (1) when it calls mysql_parse; (2) when it calls THD::binlog_query. In case (1), it always clears THD::options&OPTION_BIN_LOG (because run_query() in ha_ndbcluster_binlog.cc is only called with disable_binlogging = TRUE). In case (2), it always uses qtype=STMT_QUERY_TYPE. sql/set_var.cc: Added @todo comment for post-push cleanup. sql/share/errmsg.txt: Added new error messages and clarified ER_BINLOG_UNSAFE_STATEMENT. sql/sp.cc: Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE. sql/sp_head.cc: Use member function to read current_stmt_binlog_row_based. sql/sp_head.h: Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. sql/sql_acl.cc: Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE. sql/sql_base.cc: - Made decide_logging_format take care of all logic for deciding the logging format, and for determining the related warnings and errors. See comment above decide_logging_format for details. - Made decide_logging_format a member function of THD, since it needs to access private members of THD and since its purpose is to update the state of a THD object. - Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called. sql/sql_class.cc: - Moved logic for determining unsafe warnings away from THD::binlog_query (and into decide_logging_format()). Now, it works like this: 1. decide_logging_format detects that the current statement shall produce a warning, if it ever makes it to the binlog 2. decide_logging_format sets a flag of THD::binlog_warning_flags. 3. THD::binlog_query reads the flag. If the flag is set, it generates a warning. - Use member function to read current_stmt_binlog_row_based. sql/sql_class.h: - Added THD::binlog_warning_flags (see sql_class.cc for explanation). - Made decide_logging_format() and reset_for_next_command() member functions of THD (instead of standalone functions). This was needed for two reasons: (1) the functions need to access the private member THD::binlog_warning_flags; (2) the purpose of these functions is to update the staet of a THD object, so from an object-oriented point of view they should be member functions. - Encapsulated current_stmt_binlog_row_based, so it is now private and can only be accessed from a member function. Also changed the data type to an enumeration instead of a bool. - Removed MYSQL_QUERY_TYPE, because it was equivalent to STMT_QUERY_TYPE anyways. - When reset_current_stmt_binlog_row_based was called from the ndb_binlog thread, it would behave as a no-op. This special case has been removed, and the behavior of reset_current_stmt_binlog_row_based does not depend on which thread calls it any more. The special case did not serve any purpose, since the ndb binlog thread did not take the current_stmt_binlog_row_based flag into account anyways. sql/sql_delete.cc: - Moved logic for setting row format for DELETE..LIMIT away from mysql_prepare_delete. (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy) and rely on decide_logging_format() (sql_class.cc) to set row format.) This is part of the fix for BUG#45831. - Use member function to read current_stmt_binlog_row_based. sql/sql_insert.cc: - Removed unnecessary calls to thd->lex->set_stmt_unsafe() and thd->set_current_stmt_binlog_row_based_if_mixed() from handle_delayed_insert(). The calls are unnecessary because they have already been made; they were made in the constructor of the `di' object. - Since decide_logging_format() is now a member function of THD, code that calls decide_logging_format() had to be updated. - Added DBUG_ENTER call, to be able to trace when set_stmt_unsafe is called. - Moved call to set_stmt_unsafe() for INSERT..SELECT..LIMIT away from mysql_insert_select_prepare() (and into decide_logging_format). This is part of the fix for BUG#45831. - Use member function to read current_stmt_binlog_row_based. sql/sql_lex.h: - Added the flag BINLOG_STMT_FLAG_ROW_INJECTION to enum_binlog_stmt_flag. This was necessary so that a statement can identify itself as a row injection. - Added appropriate setter and getter functions for the new flag. - Added or clarified some comments. - Added DBUG_ENTER() sql/sql_load.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_parse.cc: - Made mysql_reset_thd_for_next_command() clear thd->binlog_warning_flags. - Since thd->binlog_warning_flags is private, it must be set in a member function of THD. Hence, moved the body of mysql_reset_thd_for_next_command() to the new member function THD::reset_thd_for_next_command(), and made mysql_reset_thd_for_next_command() call THD::reset_thd_for_next_command(). - Removed confusing comment. - Use member function to read current_stmt_binlog_row_based. sql/sql_repl.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_table.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_udf.cc: Use member function to read current_stmt_binlog_row_based. sql/sql_update.cc: Moved logic for setting row format for UPDATE..LIMIT away from mysql_prepare_update. (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy) and rely on decide_logging_format() (sql_class.cc) to set row format.) This is part of the fix for BUG#45831. sql/sql_yacc.yy: Made INSERT DELAYED, INSERT..SELECT..LIMIT, UPDATE..LIMIT, and DELETE..LIMIT mark themselves as unsafe at parse time (instead of at execution time). This is part of the fixes BUG#45831 and BUG#45825. storage/example/ha_example.cc: Made exampledb accept inserts. This was needed by the new test case rpl_ndb_binlog_format_errors, because it needs an engine that is statement-only (and accepts inserts). storage/example/ha_example.h: Made exampledb a statement-only engine instead of a row-only engine. No existing test relied exampledb's row-only capabilities. The new test case rpl_ndb_binlog_format_errors needs an engine that is statement-only. storage/innobase/handler/ha_innodb.cc: - Changed error error code and message given by innodb when binlog_format=STATEMENT and transaction isolation level is READ COMMITTED or READ UNCOMMITTED. - While I was here, also simplified the condition for checking when to give the error. |

Bug#31552 Replication breaks when deleting rows from out-of-sync table
without PK Bug#31609 Not all RBR slave errors reported as errors bug#32468 delete rows event on a table with foreign key constraint fails The first two bugs comprise idempotency issues. First, there was no error code reported under conditions of the bug description although the slave sql thread halted. Second, executions were different with and without presence of prim key in the table. Third, there was no way to instruct the slave whether to ignore an error and skip to the following event or to halt. Fourth, there are handler errors which might happen due to idempotent applying of binlog but those were not listed among the "idempotent" error list. All the named issues are addressed. Wrt to the 3rd, there is the new global system variable, changeble at run time, which controls the slave sql thread behaviour. The new variable allows further extensions to mimic the sql_mode session/global variable. To address the 4th, the new bug#32468 had to be fixed as it was staying in the way. include/my_bitmap.h: basic operations with bits of an integer type are added. mysql-test/extra/rpl_tests/rpl_foreign_key.test: regression test for bug#32468 mysql-test/extra/rpl_tests/rpl_row_basic.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/extra/rpl_tests/rpl_row_tabledefs.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl/r/rpl_foreign_key_innodb.result: results changed mysql-test/suite/rpl/r/rpl_idempotency.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_11bugs.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_2myisam.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_3innodb.result: results changed mysql-test/suite/rpl/r/rpl_row_mystery22.result: results changed mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: results changed mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: results changed mysql-test/suite/rpl/r/rpl_temporary_errors.result: results changed mysql-test/suite/rpl/t/rpl_idempotency.test: extenstions to the test providing testing of complements to the idempotent error set and checking how slave halts when it faces an error from the list when the mode is STRICT. mysql-test/suite/rpl/t/rpl_row_basic_11bugs.test: changes due to bug#31552/31609 idempotency is not default any longer. mysql-test/suite/rpl/t/rpl_row_mystery22.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl/t/rpl_temporary_errors.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl_ndb/r/rpl_ndb_dd_advance.result: results changed mysql-test/suite/rpl_ndb/r/rpl_row_basic_7ndb.result: results changed sql/log_event.cc: the fix for bug#32468 delete rows event on a table with foreign key constraint fails ensures the flags are set at proper time so that their values will be caught by innodb. reseting the flags is done along the common error and errorless execution path. The list of idempotent error is extended with foreign keys related items. NDB engine write events are designed with the replace sematics in mind. Therefore the corrsponding ndb handler's flag are (re)set regardless of the slave's execution mode. Rows_log_event::write_row() starts using the bool replace argument as its caller sets it depending on the event's execution mode. sql/log_event.h: adding a new member to hold the slave's mode during execution of the event. sql/mysql_priv.h: changes to link the command line option with the new global sys var. sql/mysqld.cc: introduction of the new command line option. providing its initialization to a default. changes to link the command line option with the new global sys var. sql/rpl_rli.cc: rli post-event-execution cleanup restores the default bits. sql/set_var.cc: The new "standard" sys_var_set class' and the new global system var related declarations and definitions. fix_slave_exec_mode() is used as with the update method of a new class so as at time of the command line arguments parsing. sql/set_var.h: new declarations. The class for the new global sys var is based on yet another new "standard" one. sql/share/errmsg.txt: slave_exec_mode setting error; slave inconsistency error which may be not an error when the intention is "idempotent". I.e consisting of row-based events binlog is being applied for the 2nd (more) time. sql/sql_class.h: The names for the bits of the new sever slave_exec_mode_options. mysql-test/suite/rpl/t/rpl_idempotency-master.opt: innodb is necessary mysql-test/suite/rpl/t/rpl_idempotency-slave.opt: innodb is necessary, as well as the tests start with non-default IDEMPOTENT slave execution mode. |

BUG#31702 (Missing row on slave causes assertion failure under row-based
replication): Incremental patch to enable idempotency support for update events again. The final handling of errors will be done in BUG#31609, and until then the handling of errors should be consistent between the different types of changes. mysql-test/suite/rpl/r/rpl_row_basic_11bugs.result: Result change. mysql-test/suite/rpl/r/rpl_temporary_errors.result: Result change. mysql-test/suite/rpl/t/rpl_row_basic_11bugs.test: Changing test to assume idempotency handling of update event. mysql-test/suite/rpl/t/rpl_temporary_errors.test: Changing test to assume idempotency handling of update event. sql/log_event.cc: Incremental patch to enable idempotency support for the update events again. The real error handling will be implemented in BUG#31609. |

BUG#24860 (Incorrect SLAVE_TRANSACTION_RETRIES code can result in slave stuck):
If a temporary error occured inside a group on an event that was not the first event of the group, the slave could get stuck because the retry counter is reset whenever an event was executed successfully. This patch only reset the retry counter when an entire group has been successfully executed, or failed with a non-transient error. sql/slave.cc: Adding debug printouts to every place where Relay_log_info::trans_retries is changed and to has_temporary_error() to print the error when returning. Adding debug variable all_errors_are_temporary_errors to make all errors for slave thread temporary errors. Adding code so that the Relay_log_info::trans_retries is only reset when an entire group was sucessfully executed, or a non-temporary error occured. mysql-test/suite/rpl/r/rpl_temporary_errors.result: New BitKeeper file ``mysql-test/suite/rpl/r/rpl_temporary_errors.result'' mysql-test/suite/rpl/t/rpl_temporary_errors-slave.opt: New BitKeeper file ``mysql-test/suite/rpl/t/rpl_temporary_errors-slave.opt'' mysql-test/suite/rpl/t/rpl_temporary_errors.test: New BitKeeper file ``mysql-test/suite/rpl/t/rpl_temporary_errors.test'' |
