# ==== Purpose ====
#
# The purpose of this test is to check that crashing the replica while there
# are several XA transactions executing up until several points of `XA
# PREPARE/COMMIT/ROLLBACK` statements, will result in consistency between
# SE and TC after recovery is finished.
#
# ==== Requirements ====
#
# R1. When crashing in the middle of an XA transaction and after recovery,
# storage engine and transaction coordinator MUST be in sync.
#
# For a more detailed list of requirements for the expected state for each
# of the sync points, check the `Requirements` section for the tests listed
# in `Related tests` section of `extra/xa_crash_safe_tests/setup.inc`.
#
# ==== Implementation ====
#
# 1) Execute several `XA PREPARE` statements up until:
# a) Before preparing in the SEs.
# b) Before preparing in the TC.
# c) Before setting the transaction as prepared in TC.
# d) After writing to the TC log.
# 2) Kill the replica and restart it.
# 3) Check that:
# a) SE recovery rolled back the transaction executed in 1.a)
# b) XA recovery rolled back the transaction executed in 1.b)
# c) XA recovery left in prepared state transaction executed in 1.b) and
# 1.c)
# 4) Clean up pending transactions
# 5) Execute several `XA COMMIT` statements up until:
# a) Before starting the commit process.
# b) Before invoking the before commit hook.
# c) Before committing in SEs.
# 6) Kill the replica and restart it.
# 7) Check that:
# a) XA recovery left in prepared state transaction executed in 5.a) and
# 5.b)
# b) XA recovery committed the transaction executed in 5.c)
# 8) Clean up pending transactions
# 9) Execute several `XA ROLLBACK` statements up until:
# a) Before starting the rollback process.
# b) Before invoking the before commit hook.
# c) Before rolling back in SEs.
# 10) Kill the replica and restart it.
# 11) Check that:
# a) XA recovery left in prepared state transaction executed in 9.a) and
# 9.b)
# b) XA recovery rlled back the transaction executed in 9.c)
# 12) Clean up pending transactions
# 13) Execute several `XA COMMIT ... ONE PHASE` statements up until:
# a) Before preparing in SEs.
# b) Before invoking the before commit hook.
# c) Before committing in SEs.
# 14) Kill the replica and restart it.
# 15) Check that:
# a) SE recovery rolled back the transaction executed in 13.a)
# b) XA recovery rolled back the transaction executed in 13.b)
# c) XA recovery committed transaction executed in 13.c)
