# Validate that GR behaves properly when group GNOs are exhausted.
# MAX_GNO: 9223372036854775807
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Create a table t1 on both M1 and M2, before starting GR. Validate that
# transactions are aborted on local member and remote members move to ERROR
# state when group GNOs are exhausted:
# - Set GTID_PURGED=GROUP_UUID:1-9223372036854775804 on M1.
# - Bootstrap start GR on M1. Verify GTID_EXECUTED on M1.
# - Set GTID_PURGED=GROUP_UUID:1-9223372036854775804 on M2.
# - Start GR on M2. Verify GTID_EXECUTED on M2.
# - On M1, verify that DML execution failed because GNOs are exhausted.
# - On M2, verify that member_state is now ERROR.
# - Verify GTID_EXECUTED=GROUP_UUID:1-9223372036854775806 on both M1 and M2.
# - Stop GR on M1 and M2.
# 2. Validate that member start moves to ERROR state when GNOs are exhausted:
# - Set GTID_PURGED=GROUP_UUID:1-9223372036854775806 on M1.
# - Bootstrap start GR on M1. Verify that member_state is ERROR on M1.
# - Stop GR on M1.
# 3. Validate that member start moves to ERROR state when GNOs are exhausted on
# view change log:
# - Set GTID_PURGED=GROUP_UUID:1-9223372036854775804 on M1.
# - Bootstrap start GR on M1. Verify GTID_EXECUTED on M1.
# - Set GTID_PURGED=GROUP_UUID:1-9223372036854775804 on M2.
# - Start GR on M2. Verify GTID_EXECUTED on M2.
# - Stop GR on M2. Verify that member_state is ERROR on M1 due to view change
# log event.
# - Verify GTID_EXECUTED=GROUP_UUID:1-9223372036854775806 on M1. Stop GR on M1.
# 4. Clean up.
