The ESM loader does not accept a directory as the referrer, it requires
a path within the directory. Add /repl to ensure relative dynamic
imports can succeed.

Fixes: #19570

can you put in a comment explaining why the path is being modified?

@devsnek sure but to clarify are you asking for a comment about why /repl is being added or about why the test spawns using cwd in the fixtures (or both)?

Windows tests have been quite flaky today, but I don't believe it's related to this PR the most recent failure was test-worker-prof.js (which does not appear to involve the repl in any manner).

A backport of this PR is needed for 12.x. I'm a little unclear from https://github.com/nodejs/node/blob/master/doc/guides/backporting-to-release-lines.md, should I wait 2 weeks before posting a PR against v12.x-staging or do I just post now and it gets blocked for 2 weeks?

@coreyfarrell This change doesn't apply cleanly to 12.x because we haven't unflagged ESM there yet. I think we should try to land things in order or it will be difficult to correctly backport everything related to ESM.

@targos I'm aware it doesn't apply cleanly, I've done the backport in a local branch. Are you saying that ESM will get unflagged in a future 12.x? Is a list being collected of ESM stuff that needs backport to 12.x?

targos commented Dec 2, 2019

There's no list only for ESM stuff, but many PRs related to ESM are semver-minor will have to wait at least for 12.14.0 in January 2020.
