# ==== Purpose ====
#
# Bug #18963676 MISSED TO HANDLE OOM ERROR WHILE ADDING A GTID INTO GTID SET
#
# Verify that we can get correct global @@GTID_EXECUTED after server
# restarts from a crash caused by 'OUT OF MEMORY' error on adding
# GTID into global @@GTID_EXECUTED.
#
# ==== Implementation ====
#
# 1) Commit a transaction on master.
# 2) Wait the slave server crash caused by 'OUT OF MEMORY' error
# on adding GTID into @@GLOBAL.GTID_EXECUTED when applying
# the replicated transaction.
# 3) Verify that the transaction is committed and its GTID is
# added into @@GLOBAL.GTID_EXECUTED and 'gtid_executed'
# table after slave server restarts.
#
# Test in this file is binlog format agnostic, thus no need
# to rerun them for every format.
