# include/wait_slave_status.inc
#
# Created by Matthias Leich
#
# SUMMARY
#
# Waits until slave has reached certain state or maximum time reached.
#
# (This script will not work, when the SHOW command delivers more than one
# result record, because only the first record will be caught.)
#
# USAGE
#
# Set $result_pattern in test file and source this file:
#
# let $result_pattern= <pattern used for LIKE on the result of
# SHOW STATUS SLAVE>
# --include wait_slave_status.inc
#
# EXAMPLE
#
# The script rpl_until.test:
# ...
# --replace_result $MASTER_MYPORT MASTER_MYPORT
# --replace_column 1 # 9 # 23 # 33 #
# --vertical_results show slave status;
#
# outputs
# show slave status;
# Slave_IO_State #
# Master_Host 127.0.0.1
# Master_User root
# Master_Port MASTER_MYPORT

#
# The main problem with the "show slave status;" in rpl_until is, that
# depending on the total test engine power and the current load caused by
# other processes, the expected slave status might be not reached though
# it will happen in maybe some seconds.
#
# The typical problem with rpl_until is that Slave_IO_Running is "No"
# instead of "Yes".
#
# The expected result follows the LIKE pattern:
#
# let $result_pattern= '%127.0.0.1%root%1%master-bin.000001%776%slave-relay-bin.000004%master-bin.000001%Yes%No%0%0%319%Master%master-bin.000001%319%No%';
#
# The Slave_IO_Running value is the "Yes" just after the "master-bin.000001".
#
# How to get this pattern ?
#
# Any lines "--replace_result ..." and "--replace_colum ..." just before
# the SHOW TABLE STATUS and of course the expected result itself
# show us columns where the content must be unified, because it is non
# deterministic or it depends on the current test environment.
#
# Unfortunately "--replace_result ..." and "--replace_colum ..." do not
# affect the result of our assignment let $my_val= `SHOW SLAVE STATUS`;
# Therefore such content must be covered by '%'.
#
# Please be careful. A more simple pattern might be dangerous, because we
# might get "wrong" matches. Example: There might be several "Yes" and "No"
# within one result row.

| - There is a new bug within the replication.
| - We met an extreme testing environment and $max_wait is
| too small.;
