Thanks for the fix! If you are able to write a test for it, we can run it on CI and we'll see if it works on the Windows machines. /cc @bmeck |
This looks correct to me

Tested this, it fixes #15374.
Wrt to the tests, I'm not that knowledgable on how they actually get executed at a top level to know what the exact entry point is here, and as to why they weren't failing already on windows. Any end-to-end modules test should capture this - I don't think it's a specific test case. |
@guybedford you are right. I just realized that es-module tests don't run on CI yet: #15276 |
Since this has been manually verified to work should we land once 48 hours has passed? I don't think we should block on fixing the CI for this. |

Is there a reason why regex is used here instead of filename.endsWith('.mjs')
?

Habits from before that existed. Technically we could/should not be using prototype functions since they could be tainted by preloading via --require
.

There's a lot to tweak then because there's heavy use of apply
, call
, charAt
, concat
, pop
, push
, slice
, test
, and on and on. It'd be neat to see if some of this could be solved with a new context to avoid plucking all these methods off.

@jdalton Contexts are expensive w/o snapshots to create and we would need a frozen one to avoid mutations which would mean making that custom Snapshot, we couldn't use vm.createContext
due to the funky sandbox bridge it creates leaking : #6283 . I'd be open to using one if we had a snapshot, but it would still be ~10ms on my benchmarks to create a full one.

This should fix the Windows path bug with drive letters being detected as the protocol, getting modules to work on Windows properly.
I still need to actually test this out on a Windows machine (won't have access again till tomorrow) but I'm 99% sure it'll work out.
