Background: With the introduction of
.git
caching on CircleCI, the repo initialization job often ends up with an outdated view of themain
branch that is restored from the cache. This can cause our check for config freshness to incorrectly pass when it should fail. (The risk is that PRs will run an incomplete set of tests and go on to breakmain
once merged.)PR Highlights:
initialize_repo.sh
to actually updatemain
. (It was doing a fetch, but wasn't updating the localmain
branch.)Initialize Repository
