# This test checks that the slave rejects events originating
# by a server from the list of ignored originators (bug#27808 etc)
#
# phases of tests:
#
# 0. master_id new line in show slave status
# 1. syntax related:
#    a. error reporting if options clash;
#    b. overriding the old IGNORE_SERVER_IDS setup by the following
#       CHANGE MASTER ... IGNORE_SERVER_IDS= (list);
#    c. the old setup preserving by CHANGE MASTER w/o IGNORE_SERVER_IDS
#    d. resetting the ignored server ids with the empty list arg to
#       IGNORE_SERVER_IDS=()
#    e. RESET SLAVE preserves the list
#    f. RESET SLAVE ALL should empty the list.
# 2. run time related:
#    a. observing no processing events from a master listed in IGNORE_SERVER_IDS
#    b. nullifying the list and resuming of taking binlog from the very beginning with
#       executing events this time
#
# Related BUGS: Bug #18816897- IGNORE_SERVER_IDS NOT RESETTING POST RESET SLAVE ALL

--echo # === IGNORE_SERVER_IDS DOUBLES WITH DUP VALUES        ===

# The bug caused the ignore_server_list to double the set of values everytime
# the repository type changed. This was seen when changing from FILE repository
# to TABLE repository or vice-versa. For example given repository type= FILE
#  ignore_server_ids= (5, 10, 15) followed by
#  SET GLOBAL master_info_repository='TABLE';
#  would make ignore_server_ids= (5, 10, 15, 5, 10, 15).
#
#  Also a SET GLOBAL master_info_repository= FILE again would make
#  ignore_server_ids= (5, 10, 15, 5, 10, 15, 5, 10, 15, 5, 10, 15).
