Replication: new code to not modify in-memory log positions until the COMMIT
is executed, even if the transaction spans on >=2 relay logs (bug #53).
New variable relay_log_purge =0|1
New test to verify bug #53
sql/log.cc:
Now we purge a relay log only when we are sure we won't need it,
i.e. we have executed the final query (if autocommit=1) or the COMMIT.
sql/log_event.cc:
Better tracking of the relay log's name and position
lastly executed, even if we are in a transaction which spans on
2 or more relay logs.
sql/mysql_priv.h:
new option relay_log_purge (the user can now decide himself
if he wants his relay logs to be automatically purged or not,
we don't make unsafe guesses like before)
sql/mysqld.cc:
new option --innodb (replaces --skip-innodb).
Useful for the test suite : we have skip-innodb in mysql-test-run,
but we can ('-opt.info' file) choose to start the server with
InnoDB for this test only.
New option --bdb
sql/repl_failsafe.cc:
Better tracking of the relay log's name and position
lastly executed, even if we are in a transaction which spans on
2 or more relay logs.
sql/set_var.cc:
new variable relay_log_purge
sql/slave.cc:
Better tracking of the relay log's name and position
lastly executed, even if we are in a transaction which spans on
2 or more relay logs.
Now we purge a relay log only when we are sure we won't need it,

sql/slave.h:
Better tracking of the relay log's name and position
lastly executed, even if we are in a transaction which spans on
2 or more relay logs.
sql/sql_class.h:
prototypes change
sql/sql_parse.cc:
removed thd argument (was not used in the function's body)
sql/sql_repl.cc:
Better tracking of the relay log's name and position
lastly executed, even if we are in a transaction which spans on
2 or more relay logs.
Turn relay_log_purge silently off when someone does CHANGE
MASTER TO RELAY_LOG_*
