# Validate that huge GTID_EXECUTED values are properly handled on distributed
# recovery, transactions certification and certification garbage collection
# procedure.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Generate a huge GTID_EXECUTED with 70043 characters length. It will be
#    like:
#    aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:10000:10002:...:120000
# 2. Set huge GTID_EXECUTED on both M1 and M2.
# 3. Bootstrap start on M2. The huge GTID_EXECUTED will be exchanged on
#    distributed recovery process on M1.
# 4. Execute some transactions and check that nothing bad happens. Validate
#    that data is delivered to both members.
# 5. Wait for stable set propagation and certification info garbage collection.
# 6. Check that stable set is properly updated after stable set propagation and
#    certification info garbage collection.
# 7. Clean up.
