      Fix for BUG#24432 · b3a03dad
      guilhem@gbichot3.local authored
      "INSERT... ON DUPLICATE KEY UPDATE skips auto_increment values".
      When in an INSERT ON DUPLICATE KEY UPDATE, using
      an autoincrement column, we inserted some autogenerated values and
      also updated some rows, some autogenerated values were not used
      (for example, even if 10 was the largest autoinc value in the table
      at the start of the statement, 12 could be the first autogenerated
      value inserted by the statement, instead of 11). One autogenerated
      value was lost per updated row. Led to exhausting the range of the
      autoincrement column faster.
      Bug introduced by fix of BUG#20188; present since 5.0.24 and 5.1.12.
      This bug breaks replication from a pre-5.0.24 master.
      But the present bugfix, as it makes INSERT ON DUP KEY UPDATE
      behave like pre-5.0.24, breaks replication from a [5.0.24,5.0.34]
      master to a fixed (5.0.36) slave! To warn users against this when
      they upgrade their slave, as agreed with the support team, we add
      code for a fixed slave to detect that it is connected to a buggy
      master in a situation (INSERT ON DUP KEY UPDATE into autoinc column)
      likely to break replication, in which case it cannot replicate so
      stops and prints a message to the slave's error log and to SHOW SLAVE
      STATUS.
      For 5.0.36->[5.0.24,5.0.34] replication we cannot warn as master
      does not know the slave's version (but we always recommended to users
      to have slave at least as new as master).
      As agreed with support, I'll also ask for an alert to be put into
      the MySQL Network Monitoring and Advisory Service.
