# ==== Purpose ====
#
# Test that GTID-consistency violations generate warnings or errors,
# or pass with success, as expected.
#
# Generally, the following statement types are considered to be GTID
# consistency violations:
#
#  1. DML statements that mix non-transactional updates with
#     transactional updates. (Exception: non-transactional *temporary*
#     tables do not count, in case the statement is logged in row
#     format.)
#
#  2. Transactions that use non-transactional tables after having used
#     transactional tables. (Exception: non-transactional *temporary*
#     tables do not count, in case the statement is logged in row
#     format.)
#
#  3. CREATE TABLE ... SELECT.
#
#  4. CREATE TEMPORARY TABLE or DROP TEMPORARY TABLE within a
#     transaction
#
# A GTID-violating statement can pass with success, generate a
# warning, or generate an error, according to the following rules:
#
#  1. If ENFORCE_GTID_CONSISTENCY=ON, or GTID_NEXT='UUID:NUMBER', or
#     (GTID_NEXT='AUTOMATIC' and GTID_MODE=ON or ON_PERMISSIVE),
#     generate an error.
#
#  2. Otherwise, if ENFORCE_GTID_CONSISTENCY=WARN, generate a warning.
#
#  3. Otherwise, statement should pass without warning or error.
#
# ==== Implementation ====
#
# Iterate over all values of enforce_gtid_consistency.
# Iterate over all values of gtid_mode.
# For each gtid_next in automatic, anonymus, and GTID:
#   source $test_specification
#
# $test_specification must be set by the caller to one of:
# - extra/binlog/enforce_gtid_consistency_temporary.test
# - extra/binlog/enforce_gtid_consistency_create_select.test
# - extra/binlog/enforce_gtid_consistency_trx_nontrx.test
#
# Each of
# extra/binlog/enforce_gtid_consistency_[temporary|create_select|trx_nontrx].test
# contains a number of specific test scenarios. Each test scenario has
# a statement that will be tested. For some scenarios, the expectation
# is that the statement violates GTID consistency, for other scenarios
# the expectation is that the statement does not violate GTID
# consistency.  Each scenario sources
# extra/binlog_tests/enforce_gtid_consistency_statement.inc to execute
# the statement and verify that the outcome is as expected.
#
# ==== References ====

# WL#3584: Global Transaction Identifiers
# - Created the test.
# WL#7083: GTIDs: set gtid_mode=ON online
# - Rewrote the test to improve coverage and test new logic for
#   enforce_gtid_consistency.

# This test uses ONGOING_ANONYMOUS_GTID_VIOLATING_TRANSACTION_COUNT
# and ONGOING_AUTOMATIC_GTID_VIOLATING_TRANSACTION_COUNT, which are
# only define in debug mode.
