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.

# BUG#39753: Replication failure on MIXED + bit + myisam + no PK
|
|
#
|
|
# Description
|
|
# -----------
|
|
# Simple statements against a bit column cause failure in mixed-mode
|
|
# replication.
|
|
#
|
|
# Implementation is as follows:
|
|
# i) A table with two bit fields is created. One of them is a key.
|
|
# ii) A record is inserted without specifying the key value.
|
|
# iii) The record is deleted using a where clause that matches it.
|
|
# iv) repeat i-iii) for bit key that has different size, generating
|
|
# different extra bits values
|
|
# v) The slave is synchronized with master
|
|
# vi) The table is dropped on master and the slave is re-synchronized
|
|
# with master.
|
|
#
|
|
# Step v) made the bug evident before the patch, as the slave would
|
|
# fail to find the correspondent row in its database (although it did
|
|
# the insert in step ii) ).
|
|
#
|
|
# Obs
|

|
|
# This test is based on the "how to repeat" section from the bug report.
