1. Now test use fake_relay_log primitive 2. Added RESET SLAVE to include/setup_fake_relay_log.inc for removing relay log info file 3. Added RESET SLAVE to include/cleanup_fake_relay_log.inc 4. Test moved to rpl suite as rpl_binlog_auto_inc_bug33029.test 5. Updated result file

# ==== Purpose ====
|
|
#
|
|
# Setup replication from an existing relay log in the current
|
|
# connection.
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# Make sure the slave is not running and issue:
|
|
#
|
|
# let $fake_relay_log= /path/to/fake-relay-log-file.000001
|
|
# source include/setup_fake_relay_log.inc;
|
|
# START SLAVE SQL_THREAD; # setup_fake_relay_log doesn't start slave
|
|
# ...
|
|
# source include/cleanup_fake_relay_log.inc
|
|
#
|
|
# You must run the server with --relay-log=FILE. You probably want to
|
|
# run with --replicate-same-server-id too.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# First makes a sanity check, ensuring that the slave threads are not
|
|
# running. Then copies the $fake_relay_log to RELAY_BIN-fake.000001,
|
|
# where RELAY_BIN is the basename of the relay log, and updates
|
|
# RELAY_BIN.index. Finally issues CHANGE MASTER so that it uses the
|
|
# given files.
|
|
#
|
|
# ==== Side effects ====
|
|
#
|
|
# Creates a binlog file and a binlog index file, and sets
|
|
# @@global.relay_log_purge=1. All this is restored when you call
|
|
# cleanup_fake_relay_log.inc.
|
|
#
|
|
# Enables the query log.
|
|
|
|
|
|
--disable_query_log
|
|
|
|
# Print message.
