Issue 8472: Nonlinear comment threads may be unresolvable

Reported by, Mar 1 2018 Project Member

Issue description

If a thread is not linear it may be counted as unresolved even if the last comment in the thread is resolved.

For example, if a comment thread has four comments ..

Comment 1: thread root, unresolved,
  Comment 2: in reply to comment 1, unresolved,
  Comment 3: also in reply to comment 1, unresolved,
    Comment 4: in reply to comment 3, resolved

.. then the thread appears as resolved in the Gerrit UI because the final comment in the thread is marked as resolved.

However, both the `gr-comment-api#computeUnresolvedNum` method (which shows the counter in the file list rows) and the `` method (which determines the value of `unresolved_comment_count` on change details) count unresolved comments as the number of unresolved thread leaves.

Because comment 2 in this situation is a leaf (and in the UI only the final comment can be replied to) this makes the thread unresolved and unresolvable by these two measures.

I believe our decision, more than a year ago, was that the resolution state of a thread should be the most chronologically recent mutation of that state. Would investing more into that model work?

I want to say that this is the intended model overall, but that some implementations assumed linearity in the reply-chain and give incorrect answers when encountering layouts like this.

The fix I want to make can be framed as a matter of accounting for this edge-case without altering that model.
