Earlier versions of this code allowed "ref" to take any value that would be accepted by "git checkout" as a valid target of a symbolic ref. We inadvertently accepted a breaking change to upstream go-getter that broke that as part of introducing a shallow clone optimization, because shallow clone requires selecting a single branch. To restore the previous capabilities while retaining the "depth" argument, here we accept a compromise where "ref" has the stronger requirement of being a valid named ref in the remote repository if and only if "depth" is set to a value greater than zero. If depth isn't set or is less than one, we will do the old behavior of just cloning all of the refs in the remote repository in full and then switching to refer to the selected branch, tag, or naked commit ID as a separate step. This includes a heuristic to generate an additional error message hint if we get an error from "git clone" and it looks like the user might've been trying to use "depth" and "ref=COMMIT" together. We can't recognize that error accurately because it's only reported as human-oriented git command output, but this heuristic should hopefully minimize situations where we show it inappropriately. For now this is a change in the Terraform repository directly, so that we can expedite the fix to an already-reported regression. After this is released I tend to also submit a similar set of changes to upstream go-getter, at which point we can revert Terraform to using the upstream getter.GitGetter instead of our own local fork. |
