#
# Purpose:
#
# This test ensures that the mariadb-binlog CLI tool properly displays errors
# and warnings for out of order GTIDs.
#
#
# Methodology:
#
# We simulate invalid sequence numberings by manually changing gtid_seq_no to
# differ from its expected linear sequence. Specifically, we test the following
# cases:
#   Test Case 1) Sequential sequence numbers results in no warnings
#   Test Case 2) A skipped sequence number results in no warnings if all numbers
#                are monotonic (i.e. gaps in sequence number are allowed
#                provided they never decrease)
#   Test Case 3) A sequence number lower than the last processed value results
#                in a warning
#   Test Case 4) Skipping a GTID and later receiving it results in a warning
#   Test Case 5) Repeat sequence numbers result in a warning
#   Test Case 6) Warnings from different domains are all displayed
#   Test Case 7) A decreasing seq_no before a start-position is ignored
#   Test Case 8) A decreasing seq_no inside of a --start/--stop position window
#                is displayed
#   Test Case 9) Error if --stop-position is not greater than or equal to
#                --start-position
#   Test Case 10) Strict mode warnings should be independent of --offset option
#                 specification
#   Test Case 11) Strict mode warnings should be independent of
#                 --start-timestamp option specification
#   Test Case 12) Specifying multiple binary logs with a log-position start
#                 should skip GTID state verification
#   Test Case 13) If multiple binary logs should be specified but a middle log
#                 is missing, we should detect that and warn when using -vvv
#   Test Case 14) If a --stop-position GTID occurs before the first specified
#                 binlog's GLLE, error
#
# Note that test cases are tested under three scenarios:
#  1) --gtid-strict-mode should error and immediately quit with error on out of
#     order GTIDs
#  2) --skip-gtid-strict-mode -vvv should not quit early or with error when
#     encountering out of order GTIDs; however should produce warnings after
#     binlog processing
#  3) --skip-gtid-strict-mode should neither produce errors nor warnings when
#     encountering out of order GTIDs
