Removed all code relating to synchronous replication. Anything left behind would be too old and mouldy to be of any use.

Fixed for 5.0.21, 5.1.10.

No changelog entry needed. These variables were never documented because they were unused.

rpl_recovery_rank is another variable that shows up when I do a SHOW STATUS in 4.0.20, 4.1.14 and 5.0.18 mysql> SHOW VARIABLES LIKE "rpl%"; +-------------------+-------+ | Variable_name | Value | +-------------------+-------+ | rpl_recovery_rank | 0 | +-------------------+-------+ 1 row in set (0.01 sec)
Description: An incomplete feature, mis-named synchronized replication, is in the 5.0 server. There are several user-visible portions of the code. They look interesting, but should not be used, and are not documented. How to repeat: SHOW VARIABLES LIKE 'sync_rep%': | sync_replication | 0 | | sync_replication_slave_id | 0 | | sync_replication_timeout | 10 | mysqld --verbose --help: --sync-replication=# Enable synchronous replication. --sync-replication-slave-id=# Synchronous replication is wished for this slave. --sync-replication-timeout=# Synchronous replication timeout. Suggested fix: The user-visible portions of this code should be removed. The rest of the code should be documented internally as incomplete, until such time as it can be replaced by a robust solution, completed and documented, or removed entirely.
