Description
Description:
|
------------
|
This diff includes:
|
1. Make semisync buidin to completely remove overhead of plugin lock.
|
2. Remove LOCK_log requirement from dump thread
|
3. Now user threads can wait for ACK before innodb commit.
|
add rpl_semi_sync_master_wait_point to control this behavior(AFTER_COMMIT/AFTER_SYNC)
|
4. Add a new ACK thread to handle ACK from slave.
|
5. The IO thread flushs master info only when ACK is needed
|
add rpl_semi_sync_slave_delay_master to control this behavior
|
6. Fix bug#70669, if sync_binlog = 1 ,then notify dump thread after fsync of binlog file.

This patch makes the variable rpl_semi_sync_slave obsolete, which is why it was removed.
