# ==== Purpose ====
|
|
#
|
|
# Auxiliary file used by suite/rpl/t/rpl_test_framework.test
|
|
#
|
|
# The purpose is to check that the sync chain generated in
|
|
# rpl_change_topology.inc (invoked from rpl_init.inc) is correct. This
|
|
# is done in two ways:
|
|
# (1) Print the sync chain.
|
|
# (2) Execute a statement and verify that it replicates to all slaves.
|
|
#
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# Does this:
|
|
# (1) Set up a given replication topology (rpl_init.inc)
|
|
# (2) Print $rpl_sync_chain
|
|
# (3) Execute "DELETE FROM t1" and then "INSERT INTO t1" on the master
|
|
# (4) Sync and compare all servers.
|
|
# (5) Clean up the replication topology (rpl_end.inc)
|
|
#
|
|
# (Technical detail: Since DELETE FROM t1 is not executed at the end,
|
|
# some servers may have rows left in t1 from a previous invocation of
|
|
# rpl_test_framework.inc. Therefore, this file will only work in
|
|
# statement mode where "DELETE FROM t1" removes rows that exist on
|
|
# slave but not on master.)
|
|
#
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# --let $rpl_server_count= <number>
|
|
# --let $rpl_topology= <topology specification>
|
|
# --let $masters= <list of masters>
|
|
# [--let $rpl_diff_servers= <list of servers>]
|
|
# --source extra/rpl_tests/rpl_test_framework.inc
|
|
#
|
|
# Parameters:
|
|
# $next_number
|
|
# The INSERT statement will insert $next_number into t1, and
|
|
# $next_number will increase by 1.
|
|
#
|
|
# $rpl_server_count, $rpl_topology:
|
|
# See include/rpl_init.inc
|
|
#
|
|
# $masters
|
|
# This should be a list of numbers, each identifying a server.
|
|
# The DELETE and INSERT statements will be executed on all servers
|
|
# in the list.
|
|
#
|
|
# $rpl_diff_servers
|
|
# See include/rpl_diff.inc
