Copy retention leases when trim unsafe commits#37995

When a primary shard is recovered from its store, we trim the last commit (if it's unsafe). If a shard crashes before the recovery completes, we will lose the committed retention leases because they are baked in the last commit. With this change, we copy the retention leases from the last commit to the safe commit when trimming unsafe commits.

This is a getting a bit out of hand. I'm starting to wonder if we're not better off having a dedicated state file in the index/translog/shard folder that is dedicated for this. @dnhatn this is not meant specifically at this PR as you are just extending the "let's store this in a lucene commit" line of thought. I'm just starting to doubt if it is the right one... |
