phabricator: combine commit messages into the review when folding commits

Authored by mharbison72 on Mar 20 2020, 5:24 PM.



No visible changes here, until an option to enable it is added to phabsend.

This combines the Differential fields like Arcanist does, rather than simply
concatenating the text blocks. Aside from populating everything properly in the
web interface, Phabricator fails the review create/update if repeated fields are
seen as would happen with simple concatenation.

On the flip side, now that the Summary and Test Plan fields can contain data
from multiple commits, we can't just join these fields together to determine if
an amend is needed. If that were to happen, every single commit in the folded
range would get amended with the combined commit message, which seems clearly
wrong. Aside from making a minor assumption about the content of the
Differential Revision field (it seems they allow some minor variances with
spacing), this means that for folded reviews, you can't post it, go to the web
page add a missing Test Plan, and then get it added to the commit message by
re-posting it. I don't think that's a big deal.
