When a revision is a part of the route, the m-c revision is used when the c-c one would be more useful.

I pushed this to try earlier, and nothing exploded so I assume all is well. https://treeherder.mozilla.org/#/jobs?repo=try&revision=d18dc3ee70b58a73fa663c62942ae6dc07110f77

Comment on attachment 8955751 [details] Bug 1442851 - Use comm-central revision in routes; https://reviewboard.mozilla.org/r/224830/#review231450 Thanks for your contribution! This looks pretty much exactly like what I was envisioning when we talked the other day. Sorry for the delay in reviewing. I've added Dustin as a reviewer, since he is an owner of this code. After having looked at this, another option occured to me, but I think we should go with the current patch, at least for now. The constants could move to [taskcluster/ci/config.yml](https://searchfox.org/mozilla-central/source/taskcluster/ci/config.yml) (which has a [thunderbird counterpart](https://searchfox.org/comm-central/source/taskcluster/ci/config.yml)). They could then just point to the different params. That would allow indexing comm-central bracnhes by both the c-c and m-c branches. That being said, this solves the issue at hand, and keeping the indexing consistent is probably a bigger win, at least for the moment. ::: taskcluster/taskgraph/transforms/task.py:668 (Diff revision 1) > 'comm-aurora': 'comm_head_rev', > 'try-comm-central': 'comm_head_rev', > } > > + > +def get_treeherder_rev(config): I'm not sure that `treeherder_rev` is the most descriptive name, now that the use has expanded. I think `project_rev` (or maybe `branch_rev`) would be a better name. And the global constant should be changed to match the too.

Given the use of BRANCH_REV_PARAM, I think `branch_rev` makes a lot of sense.
