Jonathan Ellis commented on CASSANDRA-243:
------------------------------------------
This makes fixes (1) and (2) suggested by Jun.
It is better to leave (3) alone though. Added comment:
// we leave the old 'dirty' bits alone, so we can test for
// whether it's safe to remove a given log segment by and-ing its
dirty
// with the current one.
testing with and() is going to be a lot faster than iterating through the bits
one by one. premature optimization, perhaps, but harmless at this point.
> more commitlogheader improvement
