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.

# mysqldump.inc
|
|
#
|
|
# SUMMARY: include file to facilitate testing the quality of mysqldump output
|
|
#
|
|
# INPUTS: Two variables:
|
|
# $table_name - the name of the table that was dumped
|
|
# $mysqldumpfile - the name of the file that captured mysqldump output
|
|
#
|
|
# OUTPUTS: minor echo data:
|
|
# We 'echo' some stage information to the .result file:
|
|
# 'altering original table', 'restoring from dumpfile', 'comparing'
|
|
#
|
|
# OTHER FILES: We use include/diff_tables.inc to compare the original, renamed
|
|
# table with the 'restored' one.
|
|
#
|
|
# DESCRIPTION: This file works by being fed the name of the original table
|
|
# and a mysqldump output file. The original table is then renamed
|
|
# to <table_name>_orig, the mysqldump file is used to recreate the
|
|
# table, then diff_tables.inc is called to compare them.
|
|
#
|
|
# LIMITATIONS: Does *NOT* work with xml output!
|
