Also, use next number for additional threads if explicitly set

Error log gets truncated when mysqld is restarted by MTR

Bug#42888 for MySQL 5.1. Add collections of test runs to make it both configurable and transparent what kinds of tests we run during integration testing. Implement filter list in mysql-test-run.pl to filter out failures of experimental test cases, using a new status code "exp-fail", so we can tell regressions ("fail") from failures of test cases that are still in development ("exp-fail").

transparent what kinds of tests we run during integration testing.

TRUNCATE TABLE fails to replicate when stmt-based binlogging is not supported.

Correcting some tests that was failing in pushbuild as well as fixing result
file for some tests that are not executed in the default MTR run.

mysql-test/suite/binlog/t/binlog_truncate_innodb.test:
  Need to reset master to avoid the check to be for the wrong binlog file.

  Need to reset master to avoid the check to be for the wrong binlog file.

Post-merge fixes. Changes to some result sets.

  TRUNCATE TABLE is not transactional, hence does not have BEGIN/COMMIT around itself.

Perl crashes when MTR 2 tries to start v1
Replaced require with system()

mysql-test/t/null.test:
  Revert fix for bug 33699.

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.
