Edit File: show_rpl_debug_info.inc

# ==== Purpose ====
#
# Print status information for replication, typically used to debug
# test failures.
#
# The following is printed on the current connection:
#
#   SELECT NOW()
#   SHOW SLAVE STATUS
#   SHOW MASTER STATUS
#   SHOW PROCESSLIST
#   SHOW BINLOG EVENTS IN <binlog_name>
#
# Where <binlog_name> is the currently active binlog.
#
# Then, the same is printed from all connections configured by
# rpl_init.inc - i.e., on connection server_N, where
# 1 <= N <= $rpl_server_count
#
#
# ==== Usage ====
#
# [--let $rpl_only_current_connection= 1]
# --source include/show_rpl_debug_info.inc
#
# Parameters:
#   $rpl_only_current_connection
#     By default, debug info is printed from all connections, starting
#     with the current connection. If this variable is set, debug
#     info is printed only for the current connection.
#     
#
# ==== Side effects ====
#
# Turns on enable_query_log, enable_result_log, enable_warnings,
# horizontal_results, and enable_abort_on_error.
#
# Prints non-deterministic output to the query log.  This file should
# never be called in a test that does not fail.
