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 ====
|
|
#
|
|
# Waits until the IO thread of the current connection has got an
|
|
# error, or until a timeout is reached. Also waits until the IO
|
|
# thread has completely stopped.
|
|
#
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# --let $slave_io_errno= NUMBER [, NUMBER ...]
|
|
# [--let $show_slave_io_error= 1]
|
|
# [--let $slave_io_error_is_nonfatal= 1]
|
|
# [--let $rpl_debug= 1]
|
|
# [--let $slave_timeout= NUMBER]
|
|
# --source include/wait_for_slave_io_error.inc
|
|
#
|
|
# Parameters:
|
|
# $slave_io_errno
|
|
# The expected IO error numbers. This can be either a single
|
|
# number, or a comma-separated list of numbers. Examples:
|
|
# --let $slave_io_errno= 1040, 1053, 2002, 2003, 2006, 2013
|
|
# --let $slave_io_errno= 1045
|
|
# (After BUG#41956 has been fixed, this will be required to be
|
|
# symbolic names instead of numbers.)
|
|
#
|
|
# $show_slave_io_error
|
|
# If set, will print the error to the query log.
|
|
#
|
|
# $slave_io_error_is_nonfatal
|
|
# By default, we wait for the slave IO thread to stop completely
|
|
# (i.e., until Slave_IO_State is empty). If this variable is set,
|
|
# then we don't wait. This is useful if the error is non-fatal
|
|
# (e.g., temporary connection error) and does not cause the slave
|
|
# IO thread to stop.
|
|
#
|
|
# $slave_timeout
|
|
# See include/wait_for_slave_param.inc
|
|
#
|
|
# $rpl_debug
|
|
# See include/rpl_init.inc
