- Allow "CHARACTER SET cs COLLATE cl" in
SP parameters, RETURNS, DECLARE
- Minor reorganization for "ASCII" and "UNICODE"
related rules, to make the code more readable,
also to allow these aliases:
* "VARCHAR(10) ASCII BINARY" -> CHARACTER SET latin1 COLLATE latin1_bin
* "VARCHAR(10) BINARY ASCII" -> CHARACTER SET latin1 COLLATE latin1_bin
* "VARCHAR(10) UNICODE BINARY" -> CHARACTER SET ucs2 COLLATE ucs2_bin
* "VARCHAR(10) BINARY UNICODE" -> CHARACTER SET ucs2 COLLATE ucs2_bin
Previously these four aliases returned the error
"This version of MySQL does not yet support return value collation".
Note:
This patch allows "VARCHAR(10) CHARACTER SET cs COLLATE cl"
and the above four aliases.
"VARCHAR(10) COLLATE cl" is still not allowed
i.e. when COLLATE is given without CHARACTER SET.
If we want to support this, we need an architecture decision
which character set to use by default.
Non-transactional updates that take place inside a transaction present problems
for logging because they are visible to other clients before the transaction
is committed, and they are not rolled back even if the transaction is rolled
back. It is not always possible to log correctly in statement format when both
transactional and non-transactional tables are used in the same transaction.
In the current patch, we ensure that such scenario is completely safe under the
ROW and MIXED modes.

Implemented the server infrastructure for the fix:
1. Added a function LEX_STRING *thd_query_string(THD) to return
a LEX_STRING structure instead of char *.
This is the function that must be called in innodb instead of
thd_query()
2. Did some encapsulation in THD : aggregated thd_query and
thd_query_length into a LEX_STRING and made accessor and mutator
methods for easy code updating.
3. Updated the server code to use the new methods where applicable.

If the log_bin_trust_function_creators option is not defined, creating a stored
function requires either one of the modifiers DETERMINISTIC, NO SQL, or READS
SQL DATA. Executing a stored function should also follows the same rules if in
STATEMENT mode. However, this was not happening and a wrong error was being
printed out: ER_BINLOG_ROW_RBR_TO_SBR.
The patch makes the creation and execution compatible and prints out the correct
error ER_BINLOG_UNSAFE_ROUTINE when a stored function without one of the modifiers
above is executed in STATEMENT mode.

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

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:

- 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:

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.
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.
Make the caller of Query_log_event, Execute_load_log_event
constructors and THD::binlog_query to provide the error code
instead of having the constructors to figure out the error code.
sql/log_event.cc:
Changed constructors of Query_log_event and Execute_load_log_event to accept the error code argument instead of figuring it out by itself
sql/log_event.h:
Changed constructors of Query_log_event and Execute_load_log_event to accept the error code argument
Make the caller of Query_log_event, Execute_load_log_event
constructors and THD::binlog_query to provide the error code
instead of having the constructors to figure out the error code.
MySQL crashes if a user without proper privileges attempts to create a procedure.
The crash happens because more than one error state is pushed onto the Diagnostic
area. In this particular case the user is denied to implicitly create a new user
account with the implicitly granted privileges ALTER- and EXECUTE ROUTINE.
The new account is needed if the original user account contained a host mask.
A user account with a host mask is a distinct user account in this context.
An alternative would be to first get the most permissive user account which
include the current user connection and then assign privileges to that
account. This behavior change is considered out of scope for this bug patch.
The implicit assignment of privileges when a user creates a stored routine is a
considered to be a feature for user convenience and as such it is not
a critical operation. Any failure to complete this operation is thus considered
non-fatal (an error becomes a warning).
The patch back ports a stack implementation of the internal error handler interface.
This enables the use of multiple error handlers so that it is possible to intercept
and cancel errors thrown by lower layers. This is needed as a error handler already
is used in the call stack emitting the errors which needs to be converted.

When the thread executing a DDL was killed after finished its
execution but before writing the binlog event, the error code in
the binlog event could be set wrongly to ER_SERVER_SHUTDOWN or
ER_QUERY_INTERRUPTED.
This patch fixed the problem by ignoring the kill status when
constructing the event for DDL statements.
This patch also included the following changes in order to
provide the test case.
1) modified mysqltest to support variable for connection command
2) modified mysql-test-run.pl, add new variable MYSQL_SLAVE to

The crash was caused by freeing the internal parser stack during the parser
execution.
This occured only for complex stored procedures, after reallocating the parser
stack using my_yyoverflow(), with the following C call stack:
- MYSQLparse()
- any rule calling sp_head::restore_lex()
- lex_end()
- x_free(lex->yacc_yyss), xfree(lex->yacc_yyvs)
The root cause is the implementation of stored procedures, which breaks the
assumption from 4.1 that there is only one LEX structure per parser call.
The solution is to separate the LEX structure into:
- attributes that represent a statement (the current LEX structure),
- attributes that relate to the syntax parser itself (Yacc_state),
so that parsing multiple statements in stored programs can create multiple
LEX structures while not changing the unique Yacc_state.
Now, Yacc_state and the existing Lex_input_stream are aggregated into
Parser_state, a structure that represent the complete state of the (Lexical +
Syntax) parser.

slave
The stored-routine code took the contents of the (lowest) parser
and copied it directly to the binlog, which causes problems if there
is a special case of interpretation at the parser level -- which
there is, in the "/*!VER */" comments. The trailing "*/" caused
errors on the slave, naturally.
Now, since by that point we have /properly/ created parse-tree (as
the rest of the server should do!) for the stored-routine CREATE, we
can construct a perfect statement from that information, instead of
writing uncertain information from an unknown parser state.
Fortunately, there's already a function nearby that does exactly
that.

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