#18196 landed shortly before #17489. The latter ends up dropping the V8 cherry-picks contained in the former. This PR cherry-picks them back.

Since this change is arguably changing ABI do we need to bump module version? or is it close enough to the 6.4 land that we can shrug it off?

ABI changes on master are okay. ABI changes on release branches would have been problematic.

@ofrobots we do arguably bump the module version number on master every time though

@kfarnung

If I'm understanding the issue correctly it wasn't even possible to build node after the 6.4 changes landed. If that's the case then I don't think ABI compatibility is a problem here.

@MylesBorins it makes sense to bump the MODULE_VERSION each time a new V8 is picked up; but I don't think that locks us into a precise V8 ABI during the lifetime of that version of V8 on master. I think the idea is to signal some level of compatibility of the ABI through the MODULE_VERSION (e.g. the bump indicates that it is not compatible with master+V8-6.3), but at the same time, we don't guarantee that ABI won't change until it is released.

V8-CI is failing

v8tests.cctest/test-bytecode-generator/ClassFields --nohard-abort

Should we back out 6.4 and figure out the fix separately?

V8-CI on master for comparison

https://ci.nodejs.org/job/node-test-commit-v8-linux/1178/

That test failure suggests that some V8 commit was landed with --whitespace=fix. Some of the V8 tests are sensitive to whitespace. Let me look at the commits in #17489.

@MylesBorins

OH NO! that was totally me when I landed the original PR. ugh I'm sorry. Since nothing else has landed on master should we force push?

@ofrobots

Yep, 4c4af64 contains the change to ClassFields.golden. @MylesBorins did you land that with --whitespace=fix by any chance?

Force push window is only about 10 minutes. Please don't. I've rebased things since this landed.

jasnell commented Jan 25, 2018

In other words, please go with a new corrective commit rather than a force push.

@jasnell I'll submit a new PR to fix this

@ofrobots

Personally, I don't think the V8-CI is absolutely critical to be green. I think we should fix the whitespace issue in ClassFields.golden in a follow up.

Added to the PR. New V8-CI is at https://ci.nodejs.org/view/All/job/node-test-commit-v8-linux/1179/, but I am not going to wait for it, it is more important to fix the Node CI. Can I get a quick LGTM on this last commit: 20c1fce.
