#
# The purpose of this test is to demonstrate:
# 1) The behaviour of the before_commit hook placed in binlog.cc and all
# possible return values.
# 2) All the possible ramifications of the execution of the Transaction Context
# Service and its behaviour in the server.
#
# One will then test:
# 1) before_commit failure
# 2) Transaction Context Service reports that parameters are invalid
# 3) Transaction Context Service reports that the transaction must abort
# 4) Transaction Context Service reports OK without generating a GTID
# 5) Transaction Context Service reports OK generating a GTID internally
