Description
Notes:
- The test case is non-deterministic, run with --repeat=N. It usually fails for me in a few attempts, but it can vary on different machines and builds.
- The failure is rr-able via MTR --rr, although it may take more attempts.
- The problem is scalable at least to some extent, it is not limited to the degenerate 4K value. I initially got it on 4M value (which is also low) with a much bigger test case, so there is no reason to think it cannot be increased even further. However, it requires very specific event/binlog sizes.
- Binlog rotation prior to the flow as well as FLUSH STATUS performed in the while loop apparently doesn't do anything other than fill the binary log space.
