################################################################################ # Validate that when a member is stopped with holes on group # gtids, those holes will be filled by the next transactions. # # Test: # 0. The test requires two servers: M1 and M2. # 1. Bootstrap start a group on M1 and create a table on it. # 2. Start GR on M2. Assert check that both members have 3 GTIDs. Stop GR on M2. # 3. Execute transactions with specificed GTIDs to create holes on GTID_EXECUTED # on M1. # 4. Shutdown the group i.e. stop GR on M1 too. # - GTID_EXECUTED must contain holes. # - Bootstrap start a group on M1. # - GTID_EXECUTED must contain no holes. # - Assert check the events sequence in binlog of M1. # 5. Start GR on M2. # - GTID_EXECUTED must contain no holes. # - Assert check the events sequence in binlog of M2. # 6.
