what do i put in the node-test-commit-v8-linux config

bnoordhuis · 2018-04-13T19:38:24Z

Your username and branch name. There's a way to specify the PR but I always forget the syntax - it's something like refs/pulls/20016/head. Won't hurt to try, worst case the checkout fails and you try again.

@devsnek is this ABI breaking?
Congrats on V8 contrib 🎉

devsnek · 2018-04-14T01:51:41Z

@MylesBorins it just adds a new method to v8::Value, that's not "breaking" right? i'll add semver-minor for new util.types method i suppose

jdalton · 2018-05-08T15:17:13Z

Probably should have only exposed this with --experimental-modules.
I believe this may be the only API related to experimental modules that is now public (unflagged).
It's currently undocumented in Node v10.

MylesBorins · 2018-05-08T16:36:13Z

@jdalton this has now landed in V8 so we can't really flag the feature. We could flag the util, do you think that makes sense?

jdalton · 2018-05-08T16:44:10Z

Yep, makes sense. l'm talking about the exposed user facing bit not v8 internals bit.

devsnek · 2018-05-08T16:44:14Z

I think it should just be documented, not flagged. there is nothing experimental about this api.

jdalton · 2018-05-08T16:52:19Z

It's only useful with experimental modules or experimental vm-modules.
Shrug, it's a wart for the foreseeable future (until ESM lands).

devsnek · 2018-05-08T17:05:45Z

without esm landing, vm.Module and c++ add-ons exist which can both produce module namespaces. I can open a pr to add the docs during my lunch break later today.

jdalton · 2018-05-08T17:08:22Z

The vm.Module is behind the --experimental-vm-modules flag
(the unit test in this commit requires it).

A flag, any flag, is fine... just probably not public unflagged at the moment.

Update:

Related PR doc which makes it officially exposed is #20616. It's marked as fast-track so if there are objections to it in favor of flagging you might raise them sooner than later.
