0498988b48 Bug#30102: Rename table does corrupt tables with partition files on failure
Problem was that a failing rename just left the partitions at the state
it was at the failure.

Solution was to try to revert the started rename if a failure occured.

  New result file
mysql-test/t/partition_not_embedded.test:
  Bug#30102: Rename table does corrupt tables with partition files on failure
  
  New test file
  (list_files does not report the files in embedded)
sql/ha_partition.cc:
  Bug#30102: Rename table does corrupt tables with partition files on failure
  
  Better error handling for rename partitions (reverting the started rename
  operation)
  
  Different order of files for delete.
sql/handler.cc:
  Bug#30102: Rename table does corrupt tables with partition files on failure
  
  Tries to remove as many table files as possible
  if the first delete succeeds.

342553252f Fix for BUG#18828 - If InnoDB runs out of undo slots,
it returns misleading 'table is full'

Innodb returns a misleading error message "table is full" 
when the number of active concurrent transactions is greater
than 1024.

Fixed by adding errorcode "ER_TOO_MANY_CONCURRENT_TRXS" to the
error codes. Innodb should return HA_TOO_MANY_CONCURRENT_TRXS
to mysql which is then mapped to ER_TOO_MANY_CONCURRENT_TRXS


Note: testcase is not written as this was reproducible only by
      changing innodb code.

extra/perror.c:
  Add error number and message for HA_ERR_TOO_MANY_CONCURRENT_TRXS

86a3e213ac Merged fix for BUG#39934 up a few revisions.
NOTE: This undoes changes by BUG#42829 in sql_class.cc:binlog_query().
I will revert the change in a post-push fix (the binlog filter should
be checked in sql_base.cc:decide_logging_format()).

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:

  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.

  updated result file
mysql-test/suite/rpl/r/rpl_row_idempotency.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

  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/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.

  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.

  Made exampledb a statement-only engine instead of a row-only engine.
  No existing test relied exampledb's row-only capabilities. The new

  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.

    checking when to give the error.

12f91b1d8c Bug#44672: Assertion failed: thd->transaction.xid_state.xid.is_null()
The problem is that when a optimization of read-only transactions
(bypass 2-phase commit) was implemented, it removed the code that
reseted the XID once a transaction wasn't active anymore:

sql/sql_parse.cc:

-  bzero(&thd->transaction.stmt, sizeof(thd->transaction.stmt));
-  if (!thd->active_transaction())
-    thd->transaction.xid_state.xid.null();
+  thd->transaction.stmt.reset();

This mostly worked fine as the transaction commit and rollback
functions (in handler.cc) reset the XID once the transaction is
ended. But those functions wouldn't reset the XID in case of
a empty transaction, leading to a assertion when a new starting
a new XA transaction.

The solution is to ensure that the XID state is reset when empty
transactions are ended (by either commit or rollback). This is
achieved by reorganizing the code so that the transaction cleanup
routine is invoked whenever a transaction is ended.

innodb_flush_method=wrong_value causes crash

Problem: after a failed plugin initialization, incompletely

      as we use it as a sign that ha_initialize_handlerton() is failed,
      which is used in ha_finalize_handlerton().
    - do the same if there's no free slot for a plugin in the
      hton2plugin[] array or there are too many storage engines.

dcd050c550 Bug #34707: Row based replication: slave creates table within wrong database
The failure was caused by executing a CREATE-SELECT statement that creates a
table in another database than the current one. In row-based logging, the
CREATE statement was written to the binary log without the database, hence
creating the table in the wrong database, causing the following inserts to
fail since the table didn't exist in the given database.

Fixed the bug by adding a parameter to store_create_info() that will make
the function print the database name before the table name and used that
in the calls that write the CREATE statement to the binary log. The database
name is only printed if it is different than the currently selected database.

The output of SHOW CREATE TABLE has not changed and is still printed without
the database name.

statement (for example top-statement is a multi-row INSERT,
and trigger is ON INSERT), and that trigger inserted into an auto_increment
column, then gaps could be observed in the auto_increment sequence,
even if there were no other users of the database (no concurrency).
It was wrong usage of THD::auto_inc_intervals_in_cur_stmt_for_binlog.
Note that the fix changes "class handler", I'll tell the Storage Engine API team.

mysql-test/r/trigger-trans.result:
  result; before the bugfix, the sequence was 1,2,4,6,8,10,12...
mysql-test/t/trigger-trans.test:
  test for BUG#31612
sql/handler.cc:
  See revision comment of handler.h.
  As THD::auto_inc_intervals_in_cur_stmt_for_binlog is cumulative
  over all trigger invokations by the top statement, the
  second invokation of the trigger arrived in handler::update_auto_increment()
  with already one interval in
  THD::auto_inc_intervals_in_cur_stmt_for_binlog. The method thus
  believed it had already reserved one interval for that invokation,
  thus reserved a twice larger interval (heuristic when we don't know
  how large the interval should be: we grow by powers of two). InnoDB
  thus increased its internal per-table auto_increment counter by 2
  while only one row was to be inserted. Hence a gap in the sequence.
  The fix is to use the new handler::auto_inc_intervals_count.
  Note that the trigger's statement knows how many rows it is going
  to insert, but provides estimation_rows_to_insert == 0 (see comments
  in sql_insert.cc why triggers don't call handler::ha_start_bulk_insert()).
  * removing white space at end of line
  * we don't need to maintain THD::auto_inc_intervals_in_cur_stmt_for_binlog
  if no binlogging or if row-based binlogging. Using auto_inc_intervals_count in
  the heuristic makes the heuristic independent of binary logging, which is good.
sql/handler.h:
  THD::auto_inc_intervals_in_cur_stmt_for_binlog served
   - for binlogging
   - as a heuristic when we have no estimation of how many records the
     statement will insert.
  But the first goal needs to be cumulative over all statements which
  form a binlog event, while the second one needs to be attached to each
  statement. THD::auto_inc_intervals_in_cur_stmt_for_binlog is cumulative,
  leading to BUG#31612. So we introduce handler::auto_inc_intervals_count
  for the second goal. See the revision comment of handler.cc.
  A smaller issue was that, even when the binlog event was only one
  statement (no triggers, no stored functions),
  THD::auto_inc_intervals_in_cur_stmt.nb_elements() could be lower than
  the number of reserved intervals (fooling the heuristic), because its
  append() method collapses two contiguous intervals in one.
  Note that as auto_inc_intervals_count is in class 'handler' and not
  in class 'THD', it does not need to be handled in
  THD::reset|restore_sub_statement_state().
sql/log.cc:
  Comment is wrong: if auto_increment is second, in handler::update_auto_increment()
  'append' is false and so auto_inc_intervals_in_cur_stmt_for_binlog
  is empty, we do not come here.

2ed99fbe1c Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine.
This patch contains fixes for two problems:

1. As originally reported, the server crashed on Mac OS X when trying to access
   an EXAMPLE table after the EXAMPLE plugin was installed.

   It turned out that the dynamically loaded EXAMPLE plugin called the
   function hash_earch() from a Mac OS X system library, instead of
   hash_earch() from MySQL's mysys library. Makefile.am in storage/example
   does not include libmysys. So the Mac OS X linker arranged the hash_search()
   function to be linked to the system library when the shared object is
   loaded.

   One possible solution would be to include libmysys into the linkage of
   dynamic plugins. But then we must have a libmysys.so, which must be
   used by the server too. This could have a minimal performance impact,
   but foremost the change seems to bee too risky at the current state of
   MySQL 5.1.

   The selected solution is to rename MySQL's hash_search() to my_hash_search()
   like it has been done before with hash_insert() and hash_reset().

   Since this is the third time, we need to rename a hash_*() function,
   I did renamed all hash_*() functions to my_hash_*().

   To avoid changing a zillion calls to these functions, and announcing
   this to hundreds of developers, I added defines that map the old names
   to the new names.

   This change is in hash.h and hash.c.

2. The other problem was improper implementation of the handlerton-to-plugin
   mapping. We use a fixed-size array to hold a plugin reference for each
   handlerton. On every install of a handler plugin, we allocated a new slot
   of the array. On uninstall we did not free it. After some uninstall/install
   cycles the array overflowed. We did not check for overflow.

   One fix is to check for overflow to stop the crashes.

   Another fix is to free the array slot at uninstall and search for a free slot
   at plugin install.

   This change is in handler.cc.



include/hash.h:
  Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine.
  Renamed hash_*() functions to my_hash_*().
  Added defines that map old names to new names.
mysys/hash.c:
  Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine.
  Renamed hash_*() functions to my_hash_*().
sql/handler.cc:
  Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine.
  Protect against a failing ha_initialize_handlerton() in ha_finalize_handlerton().
  Free hton2plugin slot on uninstall of a handler plugin.
  Reuse freed slost of the hton2plugin array.
  Protect against array overrun.

cc26bc9466 Bug #38701: Crash in String::append when inserting duplicate empty strings an uft8
SET col
                  
When reporting a duplicate key error the server was making incorrect assumptions 
on what the state of the value string to include in the error is.

Fixed by accessing the data in this string in a "safe" way (without relying on it
having a terminating 0).
      
Detected by code analysis and fixed a similar problem in reporting the foreign key
duplicate errors.

f50c4207f2 Bug#20129: ALTER TABLE ... REPAIR PARTITION ... complains that
partition is corrupt

The main problem was that ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR
PARTITION took another code path (over mysql_alter_table instead of
mysql_admin_table) which differs in two ways:
1) alter table opens the tables in a different way than admin tables do
   resulting in returning with error before it tried the command
2) alter table does not start to send any diagnostic rows to the client
   which the lower admin functions continue to use -> resulting in
   assertion crash

The fix:
Remapped ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR PARTITION to use
the same code path as ANALYZE/CHECK/OPTIMIZE/REPAIR TABLE t.
Adding check in mysql_admin_table to setup the partition list for
which partitions that should be used.


Partitioned tables will still not work with
REPAIR TABLE/PARTITION USE_FRM, since that requires moving partitions
to tables, REPAIR TABLE t USE_FRM, and check that the data still
fulfills the partitioning function and then move the table back to
being a partition.

NOTE: I have removed the following functions from the handler
interface:
analyze_partitions, check_partitions, optimize_partitions,
repair_partitions
Since they are not longer needed.

c1e54765da Bug#37402: Mysql cant read partitioned table with capital letter in the name
Problem was that ha_partition had HA_FILE_BASED flag set
(since it uses a .par file), but after open it uses the first partitions
flags, which results in different case handling for create and for
open.

Solution was to change the underlying partition name so it was consistent.
(Only happens when lower_case_table_names = 2, i.e. Mac OS X and storage
engines without HA_FILE_BASED, like InnoDB and Memory.)

(Recommit after adding rename of check_lowercase_names to
get_canonical_filename, and moved it from handler.h to mysql_priv.h)

NOTE: if a mixed case name for a partitioned table was created when
lower_case_table_name = 2 it should be renamed or dropped before using
the updated version (See bug#37402 for more info)
