"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.
