In parallel replication, there are two kinds of events which are executed in different ways. Normal events that are part of event groups/transactions are executed asynchroneously by being queued for a worker thread. Other events like format description and rotate and such are executed directly in the driver SQL thread. If the direct execution of the other events were to update the old-style position, then the position gets updated too far ahead, before the normal events that have been queued for a worker thread have been executed. So this patch adds some special cases to prevent such position updates ahead of time, and instead queues dummy events for the worker threads, so that they will at an appropriate time do the position updates instead. (Also fix a race in a test case that happened to trigger while running tests for this patch). |
