MySQL Compatibility Nomenclature was Reverted from mariadb-dump Queries in 13.X

Details

    • Q3/2026 Replic. Development

    Description

      In MDEV-37146, mariadb-dump queries information_schema.SLAVE_STATUS if the server is MariaDB 11.6+ and SHOW ALL SLAVES STATUS otherwise.
      OTOH, in MDEV-39519, mariadb-dump always queries SHOW REPLICA STATUS first and then SHOW SLAVE STATUS if the former is not supported.

      These two conflict, not just in code, but in their approaches.
      To temporarily resolve this conflict from the codebase, MDEV-39519 is currently excluded from the 13.x version series and is only present on 11.8 and 12.3.

      In the mailing list, bnestere recommended to port In MDEV-37146's information_schema.SLAVE_STATUS to MDEV-39519's attempt-based approach.
