Problem: ======== SHOW BINLOG EVENTS FROM <pos> causes a variety of failures, some of which are listed below. It is not a race condition issue, but there is some non-determinism in it. Analysis: ======== "show binlog events from <pos>" code considers the user given position as a valid event start position. The code starts reading data from this event start position onwards and tries to map it to a set of known events. Each event has a specific event structure and asserts have been added to ensure that read event data satisfies the event specific requirements. When a random position is supplied to "show binlog events command" the event structure specific checks will fail and they result in assert. Fix: ==== The fix is split into different parts. Each part addresses either an ASAN issue or an assert/crash. **Part1: Checksum based position validation when checksum is enabled** Using checksum validate the very first event read at the user specified position. If there is a checksum mismatch report an appropriate error for the invalid event. |
