# ==== Purpose ====
#
# The purpose of this test is to ensure that the server properly disregards XA
# transaction related statements that try to operate upon an unknown XID, when
# on SBR.
#
# ==== Requirements ====
#
# R1. Ensure that execution proceeds normaly after trying - and failling - to
#     execute `XA COMMIT / ROLLBACK` with an unkown XID.
#
# ==== Implementation ====
#
# Ensure that the server properly disregards XA related statements that operate
# on unknown XIDs given the following setup / statements combinations:
#
# TC1. Manual GTID and apply `XA ROLLBACK` with unkown XID
# --------------------------------------------------------
# 1) Ensure that `AUTOCOMMIT` is OFF.
# 2) Set `GTID_NEXT` to manually introduced value.
# 3) Execute a DML statement.
# 4) Execute `XA ROLLBACK` with an unknown XID.
# 5) Set `AUTOCOMMIT` to the default value so that the DML statement gets
#    commited.
#
# TC2. Manual GTID and apply `XA ROLLBACK` with unkown XID
# --------------------------------------------------------
# 1) Ensure that `AUTOCOMMIT` is OFF.
# 2) Set `GTID_NEXT` to manually introduced value.
# 3) Execute a DML statement.
# 4) Execute `XA ROLLBACK` with an unknown XID.
# 5) Set `AUTOCOMMIT` to the default value so that the DML statement gets
#    commited.
#
# TC3. Manual GTID and apply `XA ROLLBACK` to an existent XA transaction
# --------------------------------------------------------------------
# 1) Ensure that `AUTOCOMMIT` is OFF.
# 2) Set `GTID_NEXT` to manually introduced value.
# 3) Execute a DML statement.
# 4) Execute `XA ROLLBACK` with an existent XID.
# 5) Set `AUTOCOMMIT` to the default value so that the DML statement gets
#    commited.
#
# TC4. Manual GTID and apply `XA COMMIT` to an existent XA transaction
# -----------------------------------------------------------------------
# 1) Ensure that `AUTOCOMMIT` is OFF.
# 2) Set `GTID_NEXT` to manually introduced value.
# 3) Execute a DML statement.
# 4) Execute `XA COMMIT` with an existent XID.
# 5) Set `AUTOCOMMIT` to the default value so that the DML statement gets
#    commited.
