41783de549 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:

  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

  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:

  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/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.

6e69536956 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.

dac6ffb958 BUG#36197: flush tables (or little table cache) can cause crash on slave
When flushing tables, there were a slight chance that the flush was occuring
between processing of two table map events. Since the tables are opened
one by one, it might result in that the tables were not valid and that sub-
sequent locking of tables would cause the slave to crash.

The problem is solved by opening and locking all tables at once using
simple_open_n_lock_tables(). Also, the patch contain a change to open_tables()
so that pre-locking only takes place when the trg_event_map is not zero, which
was not the case before (this caused the lock to be placed in thd->locked_tables
instead of thd->lock since the assumption was that triggers would be called
later and therefore the tables should be pre-locked).

657dca9367 BUG#12092 (FOUND_ROWS() not replicated):
In BUG#30244 added FOUND_ROWS() as an unsafe function, but that
works only in mixed mode under 5.1. There is a workaround that
can be used in statement-based mode either under 5.0 or 5.1
where the result of FOUND_ROWS() is stored into a user vari-
able and used that way instead. This will replicate correctly
even under statement-based replication, since it will write
a User_var entry to the binary log. For some other cases, the
value has to be passed explicitly.

This patch adds tests to demonstrate that the workarounds docu-
mented for statement-based replication works as advertised, and
does more extensive tests for cases that does not work under sta-
tement-based replication actually work under mixed mode by switch-
ing to row-based replication.
