Nice work, this approach seems great!

Cleaned up and marking as ready for review. I updated the implementation to use a std::set instead of V8::Set. In the process the conditions cache got moved into C++, JS only creates the key (\0-separated condition names).

guybedford

Seems like a nice approach.

Ping @nodejs/modules-active-members, this is still lacking some reviews/approvals before we can land it. Adding it to the agenda in case it's still open by our next meeting. :)

I really like this PR! This falls into some things we are starting to see from the community about custom conditions like https://twitter.com/sebmarkbage/status/1234223477424447488 .

There's one C++ test that seems to fail on linuxone. I look into it briefly but I don't see a clear reason why it would fail (or what the failure really means). I'm surprised that this PR would affect low-level worker interactions but can't rule it out.

addaleax · 2020-04-02T16:11:20Z

@jkrems See #32563 – I just landed a fix for that. :) Is this still ready to land, apart from waiting for a green CI?

Yes! This should be good to go, assuming CI comes back green.

(And thanks for being on top of these build failures, much appreciated. :))
