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
- 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.
s/sleep/safe_sleep (thread safe); sleep 0/1/2/3/4/5/5/5 (get slave less late);
no message on error log (deadlock is too common sometimes), a global counter
instead (SHOW STATUS LIKE 'slave_retried_transactions').
Plus a fix for libmysql/Makefile.shared
in slave SQL thread: if a transaction fails because of InnoDB deadlock or innodb_lock_wait_timeout exceeded,
optionally retry the transaction a certain number of times (new variable --slave_transaction_retries).
