There is an inconsistency with DROP DATABASE IF EXISTS, DROP
TABLE IF EXISTS and DROP VIEW IF EXISTS: those are binlogged even
if the DB or TABLE does not exist, whereas DROP PROCEDURE IF
EXISTS does not. It would be nice or at least consistent if DROP
PROCEDURE/STATEMENT worked the same too.
Fixed DROP PROCEDURE|FUNCTION IF EXISTS by adding a call to
write_bin_log in mysql_execute_command. Checked also if all
documented "DROP (...) IF EXISTS" get binlogged. Left out DROP
SERVER IF EXISTS because it seems that it only gets binlogged when
using row event (see BUG#25705).
The problem is that a unfiltered user query was being passed as
the format string parameter of sql_print_warning which later
performs printf-like formatting, leading to crashes if the user
query contains formatting instructions (ie: %s). Also, it was
using THD::query as the source of the user query, but this
variable is not meaningful in some situations -- in a delayed
insert, it points to the table name.
The solution is to pass the user query as a parameter for the
format string and use the function parameter query_arg as the
source of the user query.
Path composition for the relay log file that is stored into the relay index
file was not correct for windows.
mysql-test language does not provide primitives for portable path composition.
Fixed with storing only the basename part of the external "fake" relay log into
the relay index file.
Safety of removal of the dirname part of the relaylog is provided by logics of
`setup_fake_relay_log' that places the fake file into @@datadir directory.
TRUNCATE TABLE fails to replicate when stmt-based binlogging is not supported.
There were two separate problems with the code, both of which are fixed with
this patch:
1. An error was printed by InnoDB for TRUNCATE TABLE in statement mode when
the in isolation levels READ COMMITTED and READ UNCOMMITTED since InnoDB
does permit statement-based replication for DML statements. However,
the TRUNCATE TABLE is not transactional, but is a DDL, and should therefore
be allowed to be replicated as a statement.
2. The statement was not logged in mixed mode because of the error above, but
the error was not reported to the client.
This patch fixes the problem by treating TRUNCATE TABLE a DDL, that is, it is
always logged as a statement and not reporting an error from InnoDB for TRUNCATE
TABLE.
Documented behaviour was broken by the patch for bug 33699
that actually is not a bug.
This fix reverts patch for bug 33699 and reverts the
UPDATE of NOT NULL field with NULL query to old
behavior.
The bug happened because filtering-out a STMT_END_F-flagged event so that
the transaction COMMIT finds traces of incomplete statement commit.
Such situation is only possible with ndb circular replication. The filtered-out
rows event is one that immediately preceeds the COMMIT query event.
Fixed with deploying an the rows-log-event statement commit at executing
of the transaction COMMIT event.
Resources that were allocated by other than STMT_END_F-flagged event of
the last statement are clean up prior execution of the commit logics.
There are two issues:
1. 6.0 uses the obsolate master-*** server options;
2. the test is not deterministic in that although master vs slave consistency is
fine, two runs of the test can have different results. The reason of the
non-determinism is the combination of
a chosen way to demo results and the ndb_autoincrement_prefetch_sz feature.
The current patch fixes the 2nd issue by putting out results via diff_table macro
instead of the former run-sensitive method.
The 1st issue is going to be fixed by a separate patch to 6.0.
Remove size of binlog file from SHOW BINARY LOGS.
Changing size of binlog file is an affect of adding or removing events to/from
binlog and it can be checked in next command of test: SHOW BINLOG EVENTS.
For SHOW BINARY LOGS statement enough to show the list of file names.
The test case proposed by the bugfix fails in bugteam trees after merging new
mtr from main. The failure is due to the fact that the binlog file location has
changed and is no more under $MYSQLTEST_VARDIR/log.
This patch fixes the test failure by setting the correct path to the binlog
file.

When using CREATE TEMPORARY TABLE LIKE to create a temporary table,
or using TRUNCATE to delete all rows of a temporary table, they
did not set the tmp_table_used flag, and cause the omission of
"SET @@session.pseudo_thread_id" when dumping binlog with mysqlbinlog,
and cause error when replay the statements.
This patch fixed the problem by setting tmp_table_used in these two
cases. (Done by He Zhenxing 2009-01-12)
The fix for BUG#20103 "Escaping with backslash does not work as expected"
was implemented too greedy though in that it not only changes the behavior
of backslashes within strings but in general, so disabling command shortcuts
like \G or \C (which in turn leads to Bug #36391: "mysqlbinlog creates invalid charset
statements").
The fix allows the escaping with backslash to take place only inside a string,
thus enabling the execution of command shortcuts and presevering the fix for
BUG#20103.
Fixing pb failures caused by mtr invokes the test with --tmpdir to which
there are sensitive operations in the test
and setup_fake_relay_log.inc also needed --secure-file-priv for its own separate
directory.
Fixed with removing SELECT INTO OUTFILE and deploying --exec echo instead in the marco.
The test's opt file should contain --secure-file-priv=$MYSQL_TEST_DIR as the test
operations deal with files located in $MYSQL_TEST_DIR.
The test fails with timeout when applying diff on two tables.
In this test case, there can be a situation when the slave is not yet synced
with the master, thence the changes may not be on the slave at diff time.
This patch addresses this issue by synchronizing master and slave before the
diff takes place.
Overriding a default value of --secure-file-priv on pb.mtr to be $MYSQLTEST_VARDIR which
makes pb's mtr happy to execute the regression test for the bug.

It's a regression issue.
The reason of the bug appeared to be an error introduced into 5.1 source code.
A piece of code in Create_file_log_event::do_apply_event() did not have test
coverage which made make test and pb unaware.
Fixed with inverting the old value of the return value from
Create_file_log_event::do_apply_event().
The rpl test suite is extended with `rpl_cross_version' the file to hold
regression cases similar to the current.
The original goal of the test, as reported on BUG #25721, is to check whether
a deadlock happens or not when concurrently CREATING/ALTERING/DROPPING the
same server. For that a procedure (p1) is created that runs the exact same
CREATE/ALTER/DROP statements for 10K iterations and two different connections
(threads - t1 and t2) call p1 concurrently. At the end of the 10K iterations,
the test checks if there was errors while running the loop (SELECT e >0).
The problem is that In some cases it may happen that one thread, t1, gets
scheduled to execute with just enough time to complete the iteration and
never bumps into the other thread t2. Meaning that t1 will never run into an
SQL exception. On the other hand, the other thread, t2, may run into t1 and
never issue any/part of its own statements because it will throw an SQLEXCEPTION.
This is probably the case for failures where only one value differs.
Furthermore, there is a third scenario: both threads are scheduled to run
interleaved for each iteration (or even one thread completes all iterations
before the other starts). In this case, both will succeed without any error.
This is probably the case for the failure that reports two different values.
This patch addresses the failure in pushbuild by removing the error counting
and the printout (SELECT > 0) at the end of the test. A timeout should occur
if the error that the test is checking surfaces.
clause server fires immediately after creating event and time between create and delete
event sometimes is enough for firing. So adding STARTS clause moves first execution in
future after drop of event
1. Added STARTS clause for CREATE EVENT.
2. Updated result file.
The next number (AUTO_INCREMENT) field of the table for write
rows events are not initialized, and cause some engines (innodb)
not correctly update the tables's auto_increment value.
This patch fixed this problem by honor next number fields if present.
Added cleanup of status variables to the end of binlog_database.
Re-recorded .result file to account for cleanup statement.
NOTE: binlog.binlog_innodb also has had an FLUSH STATUS; statement added to it as well, but
adding this cleanup as a preventative measure.
Problem 1: The test waits for an error in the slave sql thread,
then resolves the error and issues 'start slave'. However, there
is a gap between when the error is reported and the slave sql
thread stops. If this gap was long, the slave would still be
running when 'start slave' happened, so 'start slave' would fail
and cause a test failure.
Fix 1: Made wait_for_slave_sql_error wait for the slave to stop
instead of wait for error in the IO thread. After stopping, the
error code is verified. If the error code is wrong, debug info
is printed. To print debug info, the debug printing code in
wait_for_slave_param.inc was moved out to a new file,
show_rpl_debug_info.inc.
Problem 2: rpl_stm_mystery22 is a horrible name, the comments in
the file didn't explain anything useful, the test was generally
hard to follow, and the test was essentially duplicated between
rpl_stm_mystery22 and rpl_row_mystery22.
Fix 2: The test is about conflicts in the slave SQL thread,
hence I renamed the tests to rpl_{stm,row}_conflicts. Refactored
the test so that the work is done in
extra/rpl_tests/rpl_conflicts.inc, and
rpl.rpl_{row,stm}_conflicts merely sets some variables and then
sourced extra/rpl_tests/rpl_conflicts.inc.
The tests have been rewritten and comments added.
Problem 3: When calling wait_for_slave_sql_error.inc, you always
want to verify that the sql thread stops because of the expected
error and not because of some other error. Currently,
wait_for_slave_sql_error.inc allows the caller to omit the error
code, in which case all error codes are accepted.
Fix 3: Made wait_for_slave_sql_error.inc fail if no error code
is given. Updated rpl_filter_tables_not_exist accordingly.
Problem 4: rpl_filter_tables_not_exist had a typo, the dollar
sign was missing in a 'let' statement.
Fix 4: Added dollar sign.
Problem 5: When replicating from other servers than the one named
'master', the wait_for_slave_* macros were unable to print debug
info on the master.
Fix 5: Replace parameter $slave_keep_connection by
$master_connection.
