branches/5.1: fix bug#42383: Can't create table 'test.bug39438'
For embedded server, MySQL may pass in full path, which is
currently disallowed. It is needed to relax the condition by
accepting full paths in the embedded case.
Approved by: Heikki (on IM)
The problem here is that the latest innodb push contains
both MYSQL_STORAGE_ENGINE(INNOBASE) and MYSQL_STORAGE_ENGINE(INNOBASE)
in the same CMakeLists.txt, to make the resulting library
ha_innodb.dll, instead of ha_innobase.dll.
Using multiple MYSQL_STORAGE_ENGINE within the same CMakeLists.txt
conflicts with the fix for the bug Bug #47795 "CMake, storage engine
name different from directory name". Top-level CMakeLists.txt now
parses storage engine's CMakeLists.txt to extract engines name from
MYSQL_STORAGE_ENGINE().
For innodb, it concludes that there is not storage engine named
INNOBASE, hence WITH_INNOBASE_STORAGE_ENGINE has no effect.
The fix is to use SET_TARGET_PROPERTIES(... PROPERTIES OUTPUT_NAME ...),
instead of renaming the engine to have plugins named ha_innodb.dll.

CMakeLists.txt files cleanup
- remove SAFEMALLOC and SAFE_MUTEX definitions that were
present in *each* CMakeLists.txt. Instead, put them into top level
CMakeLists.txt, but disable on Windows, because
a) SAFEMALLOC does not add any functionality that is not already
present in Debug C runtime ( and 2 safe malloc one on top of the other
only unnecessarily slows down the server)
b)SAFE_MUTEX does not work on Windows and have been
explicitely disabled on Windows with #undef previously. Fortunately,
ntdll does pretty good job identifying l problems with
CRITICAL_SECTIONs.

InnoDB will return an error if statement based replication is used
along with transaction isolation level READ-COMMITTED (or weaker),
even if the statement in question is filtered out according to the
binlog-do-db rules set. In this case, an error should not be printed.
This patch addresses this issue by extending the existing check in
external_lock to take into account the filter rules before deciding to
print an error. Furthermore, it also changes decide_logging_format to
take into consideration whether the statement is filtered out from
binlog before decision is made.

branches/5.1: When the InnoDB and MySQL data dictionaries go out of sync, before
the bug fix we would assert on missing autoinc columns. With this fix we allow
MySQL to open the table but set the next autoinc value for the column to the
MAX value. This effectively disables the next value generation. INSERTs will
fail with a generic AUTOINC failure. However, the user should be able to
read/dump the table, set the column values explicitly, use ALTER TABLE to
set the next autoinc value and/or sync the two data dictionaries to resume
normal operations.

Bug#24509 - 2048 file descriptor limit on windows needs increasing, also
WL#3049 - improved Windows I/O
The patch replaces the use of the POSIX I/O interfaces in mysys on Windows with
the Win32 API calls (CreateFile, WriteFile, etc). The Windows HANDLE for the open
file is stored in the my_file_info struct, along with a flag for append mode
because the Windows API does not support opening files in append mode in all cases)
The default max open files has been increased to 16384 and can be increased further
by setting --max-open-files=<value> during the server start.
Another major change in this patch that almost all Windows specific file IO code
has been moved to a new file my_winfile.c, greatly reducing the amount of code
in #ifdef blocks within mysys, thus improving readability.
Minor enhancements:
- my_(f)stat() is changed to use __stati64 structure with 64 file size
and timestamps. It will return correct file size now (C runtime implementation
used to report outdated information)
- my_lock on Windows is prepared to handle additional timeout parameter
- after review : changed __WIN__ to _WIN32 in the new and changed code.
client/mysqlbinlog.cc:
fileno -> my_fileno
client/readline.cc:
fileno -> my_fileno
include/config-win.h:
Increase OS_FILE_LIMIT for Windows.
Remove O_SHARE - Windows does not support it. Its definition conflicts with
O_SHORT_LIVED, that has different semantics.
include/my_dir.h:
Use stat64 for stat() family of functions on Windows, because of 64 bit file size.
include/my_global.h:
Increased default value for open file limit to 16K
include/my_sys.h:
- my_file_info got new structure members - file handle and open flags
- 2 new Windows-only mysys functions : my_get_osfhandle and my_osmaperr,
modelled after Windows C runtime functions _get_osfhandle and _dosmaperr

2) it is present only in static C runtime (mysqld does not link if compiled with
/MD)

This is a post-push fix addressing review requests and
problems with extra warnings.
Problem 1: The sub-statement where an unsafe warning was detected was
printed as part of the warning. This was ok for statements that
were unsafe due to, e.g., calls to UUID(), but did not make
sense for statements that were unsafe because there was more than
one autoincrement column (unsafeness in this case comes from the
combination of several sub-statements).
Fix 1: Instead of printing the sub-statement, print an explanation
of why the statement is unsafe.
Problem 2:
When a recursive construct (i.e., stored proceure, stored
function, trigger, view, prepared statement) contained several
sub-statements, and at least one of them was unsafe, there would be
one unsafeness warning per sub-statement - even for safe
sub-statements.
Fix 2:
Ensure that each type of warning is printed at most once, by
remembering throughout the execution of the statement which types
of warnings have been printed.
mysql-test/extra/rpl_tests/create_recursive_construct.inc:
- Clarified comment per review request.
- Added checks for the number of warnings in each invocation.
mysql-test/extra/rpl_tests/rpl_insert_delayed.test:

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()).
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.

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.
mysql-test/suite/rpl/r/rpl_rbr_to_sbr.result:
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
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

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.

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.
1. BUG#21704 - Renaming column does not update FK definition
2. Changes in mysql-test/include/mtr_warnings.sql so that the testcase
for BUG#21704 doesn't fail because of the warnings generated.

Fix Bug#21704 Renaming column does not update FK definition
by checking whether a column that participates in a FK definition is being
renamed and denying the ALTER in this case.
The patch was originally developed by Davi Arnaut <Davi.Arnaut@Sun.COM>:
http://lists.mysql.com/commits/77714
and was later adjusted to conform to InnoDB coding style by me (Vasil),
I also added some more comments and moved the bug specific mysql-test to
a separate file to make it more manageable and flexible.
