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.

# ==== Purpose ====
|
|
#
|
|
# Issues STOP SLAVE on the current connection. Then waits until both
|
|
# the IO and SQL threads have stopped, or until a timeout is reached.
|
|
#
|
|
# Please use this instead of 'STOP SLAVE', to reduce the risk of races
|
|
# in test cases.
|
|
#
|
|
# This will fail if the slave IO or SQL thread has an error. If you
|
|
# expect an error in the IO thread, use
|
|
# include/wait_for_slave_io_error.inc and include/stop_slave_sql.inc.
|
|
#
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# [--let $rpl_only_running_threads= 1]
|
|
# [--let $slave_timeout= NUMBER]
|
|
# [--let $rpl_debug= 1]
|
|
# --source include/stop_slave.inc
|
|
#
|
|
# Parameters:
|
|
# $rpl_only_running_threads
|
|
# By default, this script executes STOP SLAVE unconditionally.
|
|
# This generates a warnings if one or both slave threads are
|
|
# already stopped. If $rpl_only_running_threads is set, this
|
|
# script checks which slave threads are running, and issues either
|
|
# STOP SLAVE, STOP SLAVE SQL_THREAD, STOP SLAVE IO_THREAD, or
|
|
# nothing.
|
|
#
|
|
# $slave_timeout
|
|
# See include/wait_for_slave_param.inc
|
|
#
|
|
# $rpl_debug
|
|
# See include/rpl_init.inc
