Commit Message

vinyl: do not track partial reads in tx manager

We use a binary tree for tracking reads (read_set). The tree is ordered
by (index, statement, tx). Insertion of a partial statement into the
tree may result in breaking comparison transitivity, which is mandated
by the tree implementation. However, for range requests we insert the
search key into the read set, which may be partial. This may result in a
crash in the read_set.

Tracking the search key doesn't make much sense anyway: it doesn't bring
us any closer to range request tracking, only obscures the semantics of
select. So let's track only statements actually returned by the iterator
plus gaps found by point requests.

Closes #2675
