MySQL 4.1
and Bug#16920 rpl_deadlock_innodb fails in show slave status (reported for MySQL 5.1)
- backport of several fixes done in MySQL 5.0 to 4.1
- fix for new discovered instability (see comment on Bug#12429 + Bug#16920)
- reenabling of testcases
Fix for bug#12429: Replication tests fail: "Slave_IO_Running" differs:
The value is not important, and it depends on timing. Mask it.
Backport and extension of a fix made by Matthias in 5.0, originally it was

- Fixed problem, only detect comment if the # is on start of line AND starting line of the current command.
- Wrote tests for most of the mysqltest commands, added stricter checking of correct syntax.
CREATE DATABASE statement used the current database instead of the
database created when checking conditions for replication.
CREATE/DROP/ALTER DATABASE statements are now replicated based on
the manipulated database.
Added more DBUG statements
Ensure that we are comparing end space with BINARY strings
Use 'any_db' instead of '' to mean any database. (For HANDLER command)
Only strip ' ' when comparing CHAR, not other space-like characters (like \t)
Fixed output from mysqlbinlog when using --skip-comments
Fixed warnings from valgrind
Fixed ref_length when used with HEAP tables
More efficent need_conversion()
Fixed error handling in UPDATE with not updateable tables
Fixed bug in null handling in CAST to signed/unsigned
"Add a column "Timestamp_of_last_master_event_executed" in SHOW SLAVE STATUS".
Finally this is adding
- Slave_IO_State (a copy of the State column of SHOW PROCESSLIST for the I/O thread,
so that the users, most of the time, has enough info with only SHOW SLAVE STATUS).
- Seconds_behind_master. When the slave connects to the master it does SELECT UNIX_TIMESTAMP()
on the master, computes the absolute difference between the master's and the slave's clock.
It records the timestamp of the last event executed by the SQL thread, and does a
small computation to find the number of seconds by which the slave is late.
