Sylvain Lebresne updated CASSANDRA-3716:
----------------------------------------
Attachment: 3716.patch
Attached patch that basically does 3 things:
* make sure getLocalDeletionTime is always defined, i.e, even for non-deleted
columns (it's Integer.MAX_VALUE).
* make isMarkedForDelete() be a shorthand for now >= gLDT.
* remove the uses of iMFD in all methods that should not be sensible to the
current time but rather to gcBefore.
Not sure there is really a need to do more than that.

> As explained in CASSANDRA-3579, isMarkedForDelete() depends on the current
> system clock so it can change during a two-pass compaction. Suggested fix is
> to replace iMFD + gLDT with a getExpirationTime method, so comparison with
> the compaction's gcBefore will remain constant.
