phases: large rewrite on retract boundary
The new code is still pure Python, so we still have room to going significantly
faster. However its complexity of the complex part is `O(|[min_new_draft, tip]|)` instead of
`O(|[min_draft, tip]|` which should help tremendously one repository with old
draft (like mercurial-devel or mozilla-try).
This is especially useful as the most common "retract boundary" operation
happens when we commit/rewrite new drafts or when we push new draft to a
non-publishing server. In this case, the smallest new_revs is very close to the
tip and there is very few work to do.
A few smaller optimisation could be done for these cases and will be introduced in
later changesets.
We still have iterate over large sets of roots, but this is already a great
improvement for a very small amount of work. We gather information on the
affected changeset as we go as we can put it to use in the next changesets.
This extra data collection might slowdown the `register_new` case a bit, however
for register_new, it should not really matters. The set of new nodes is either
small, so the impact is negligible, or the set of new nodes is large, and the
amount of work to do to had them will dominate the overhead the collecting
information in `changed_revs`.
As this new code compute the changes on the fly, it unlock other interesting
improvement to be done in later changeset.
# Don't run pipelines on branch "merge", since we're fast-forward only.
# Gitlab sees a new branch (since e.g. `topic/stable/my-topic` becomes
# `branch/stable`), but the hash hasn't changed. There is no reason to
# re-run the CI in our case, since we haven't built up any specific automation.
# Right now it's just wasted CI and developer time.
# One can still run the pipeline manually via the web interface,
# like in the case of releases, to make *extra* sure that the actual branch
# has succeeded.
