BUG#49978: Replication tests don't clean up replication state at the end Major replication test framework cleanup. This does the following: - Ensure that all tests clean up the replication state when they finish, by making check-testcase check the output of SHOW SLAVE STATUS. This implies: - Slave must not be running after test finished. This is good because it removes the risk for sporadic errors in subsequent tests when a test forgets to sync correctly. - Slave SQL and IO errors must be cleared when test ends. This is good because we will notice if a test gets an unexpected error in the slave threads near the end. - We no longer have to clean up before a test starts. - Ensure that all tests that wait for an error in one of the slave threads waits for a specific error. It is no longer possible to source wait_for_slave_[sql|io]_to_stop.inc when there is an error in one of the slave threads. This is good because: - If a test expects an error but there is a bug that causes another error to happen, or if it stops the slave thread without an error, then we will notice. - When developing tests, wait_for_*_to_[start|stop].inc will fail immediately if there is an error in the relevant slave thread. Before this patch, we had to wait for the timeout. - Remove duplicated and repeated code for setting up unusual replication topologies. Now, there is a single file that is capable of setting up arbitrary topologies (include/rpl_init.inc, but include/master-slave.inc is still available for the most common topology). Tests can now end with include/rpl_end.inc, which will clean up correctly no matter what topology is used. The topology can be changed with include/rpl_change_topology.inc. - Improved debug information when tests fail. This includes: - debug info is printed on all servers configured by include/rpl_init.inc - User can set $rpl_debug=1, which makes auxiliary replication files print relevant debug info. - Improved documentation for all auxiliary replication files. Now they describe purpose, usage, parameters, and side effects. - Many small code cleanups: - Made have_innodb.inc output a sensible error message. - Moved contents of rpl000017-slave.sh into rpl000017.test - Added mysqltest variables that expose the current state of disable_warnings/enable_warnings and friends. - Too many to list here: see per-file comments for details.
