Jeff Jirsa commented on CASSANDRA-13282:
----------------------------------------
Will kick off CI in a bit, not going to do all 8 tests at once because I don't
want to monopolize cassci, but links should be accurate once tests start.

> Commitlog replay may fail if last mutation is within 4 bytes of end of segment
> ------------------------------------------------------------------------------
>
> Key: CASSANDRA-13282
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13282
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Jeff Jirsa
> Assignee: Jeff Jirsa
> Fix For: 3.0.x, 3.11.x, 4.x
>
>
> Following CASSANDRA-9749 , stricter correctness checks on commitlog replay
> can incorrectly detect "corrupt segments" and stop commitlog replay (and
> potentially stop cassandra, depending on the configured policy). In
> {{CommitlogReplayer#replaySyncSection}} we try to read a 4 byte int
> {{serializedSize}}, and if it's 0 (which will happen due to zeroing when the
> segment was created), we continue on to the next segment. However, it appears
> that if a mutation is sized such that it ends with 1, 2, or 3 bytes remaining
> in the segment, we'll pass the {{isEOF}} on the while loop but fail to read
> the {{serializedSize}} int, and fail.
