# ==== Purpose ====
#
# This script tests server behavior when a crash occurs during the
# execution of `XA ROLLBACK`, just before the GTID is added to
# GTID_EXECUTED.
#
# ==== Requirements ====
#
# After server restart:
# R1. The GTID_EXECUTED variable should be updated.
# R2. There shouldn't be any pending XA transactions visible with `XA
# RECOVER`.
#
# ==== Implementation ====
#
# 1. Setup scenario: create table and insert some records.
# 2. Start and execute an XA transaction containing an insert until before
# `XA ROLLBACK`.
# 3. Take the `GTID_EXECUTED` state.
# 4. Crash the server during `XA ROLLBACK` execution before the GTID is
# added to GTID_EXECUTED.
# 5. Restart server and check:
# a. Error log for messages stating that recovery process didn't find
# any transaction needing recovery.
# b. The GTID_EXECUTED variable was updated.
# c. There aren't any pending XA transaction listed in the output of `XA
# RECOVER`.
# d. There aren't changes to the table.
