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 ====
|
|
#
|
|
# Test that temporary tables are correctly replicated after switching to ROW format in MIX mode.
|
|
# This test case will test the condition of the bug#40013.
|
|
# The test step is:
|
|
# 1: create temp table on connection 'master';
|
|
# 2: switch to ROW format using 'INSERT INTO t1 VALUES (UUID());'
|
|
# 3: disconnect 'master' and connect to a new connection 'master1';
|
|
# 4: sync to slave and check the number of temp tables on slave.

|
# BUG#43046: mixed mode switch to row format with temp table lead to wrong
|
|
# result
|
|
#
|
|
# NOTES
|
|
# =====
|
|
#
|
|
# 1. Temporary tables cannot be logged using the row-based
|
|
# format. Thus, once row-based logging is used, all subsequent
|
|
# statements using that table are unsafe, and we approximate this
|
|
# condition by treating all statements made by that client as
|
|
# unsafe until the client no longer holds any temporary tables.
|
|
#
|
|
# 2. Two different connections can use the same temporary table
|
|
# name without conflicting with each other or with an
|
|
# existing non-TEMPORARY table of the same name.
|
|
#
|
|
# DESCRIPTION
|
|
# ===========
|
|
#
|
|
# The test is implemented as follows:
|
|
# 1. create regular tables
|
|
# 2. create a temporary table t1_tmp: should be logged as statement
|
|
# 3. issue an alter table: should be logged as statement
|
|
# 4. issue statement that forces switch to RBR
|
|
# 5. create another temporary table t2_tmp: should not be logged
|
|
# 6. issue alter table on t1_tmp: should not be logged
|
|
# 7. drop t1_tmp and regular table on same statement: should log both in
|
|
# statement format (but different statements)
|
|
# 8. issue deterministic insert: logged as row (because t2_tmp still
|
|
# exists).
|
|
# 9. drop t2_tmp and issue deterministic statement: should log drop and
|
|
# query in statement format (show switch back to STATEMENT format)
|
|
# 10. in the end the slave should not have open temp tables.
