Current File : //usr/share/mysql-test/suite/binlog/t/binlog_gtid_errors.test
# ==== Purpose ====
#
# Test errors/restrictions/conditions for the following variables:
#
# - GTID_EXECUTED
# - readable, read-only, both session and global
# - GTID_PURGED
# - readable, read-only, global only
# - GTID_OWNED
# - readable, read-only, both session and global
# - GTID_NEXT
# - read-writable, session only
# - must be set to UUID:NUMBER or AUTOMATIC (when gtid_mode=ON)
# - only settable by SUPER
# - not settable from sub-statement
# - not settable from statement that also invokes sub-statement
# - not settable inside transaction
# - not settable when some gtid is owned
#
# Note: some variables related to GTIDs are tested in other files:
# GTID_MODE - rpl_gtid_mode.test
# ENFORCE_GTID_CONSISTENCY - binlog_enforce_gtid_consistency.test
# GTID_PURGED - rpl_gtid_purged_*.test
#
# ==== Implementation ====
#
# Just try all possibilities, verify that the correct error message is
# given.
#
# ==== References ====
#
# Implemented in WL#3584: Global Transaction Identifiers
