#
# 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&#039;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.
