- Clear test variables "comment" and "logfile" to make sure thay aren't
already set from previous run of same test
- Print warning if test result already set and set it anyway
in trigger
Interchangeable calls to the mysql_change_user client function
and invocations of a trigger changing some user variable caused
a memory corruption and a crash.
The mysql_change_user API call forces TDH::cleanup() on a server
that frees user variable entries.
However it didn't reset Item_func_set_user_var::entry to NULL
because Item_func_set_user_var::cleanup() was not overloaded.
So, Item_func_set_user_var::entry held a pointer to freed memory,
that caused a crash.
The Item_func_set_user_var::cleanup method has been overloaded
to cleanup the Item_func_set_user_var::entry field.

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.
The problem is that the query cache was storing partial results
if the statement failed when sending the results to the client.
This could cause clients to hang when trying to read the results
from the cache as they would, for example, wait indefinitely for
a eof packet that wasn't saved.
The solution is to always discard the caching of a query that
failed to send its results to the associated client.
- Additional patch with improved protection by putting it all inside an "eval"
- Calling 'hostpath' on a truncated socket may also croak.
- Remove the need to create any directory parts of "path" inside the function.
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.
- Fix problem with for example ./mtr --timer, caused by new version of "Getopt::Long"
- Evaluating the "$opt" variable as a string, returns the name of the parameter
to be modified instead of "Getopt::Long::Callback" which is the class name
In mtr.check_warnings, `text` was declares as type text, which is
64K, and when the server log grows larger than this, it would be
truncated, and then check_warnings was actually checking the
error messages of a previous test and complain warnings.
This patch fixed the problem by change the type of `text` to
mediumtext, which is 16M.
Log output of mysqltest when running check-testcase together
