[v12.x] deps: V8: backport postmortem metadata fixes #30870

mmarchini · 2019-12-09T22:27:02Z

V8 7.7 branch is closed, I tried backporting these commits upstream but it was not approved. These commits are necessary for llnode to work with Node.js v12.

deps/v8/BUILD.gn

don't we need the same change in v8.gyp?

I thought so, but it worked on my machine when I built it (metadata was correct in the final binary). I also couldn't find where to change on V8.gyp when I searched using grep. I think we're inferring this parameter from BUILD.gn now?

Oh yes I'm sorry, it must be one of the lists that are scraped automatically from build.gn

SmartOS failure is legit. I'll send a commit to fix it.

Reverted 59b4640 and f056d55, since string metadata name changes were reverted in v8/v8@b38dfaf3a633. cc @cjihrig

Should I land this or should I wait for someone from @nodejs/releasers to do it? I couldn't find this information on https://github.com/nodejs/node/blob/master/doc/guides/maintaining-V8.md or https://github.com/nodejs/node/blob/master/doc/guides/backporting-to-release-lines.md

Original commit message: [postmortem] update Symbol and *String metadata Symbol and *String classes are now declared on Torque with generateCppClass, which means they don't use macro accessors anymore. As such, the gen-postmortem-metadata script is not able to automatically detect fields for those classes. Define metadata for those fields manually for now. In the future we might want to generate it from Torque for consistency. Also renamed a few *String fields metadata to match the expected format (className__fieldName__fieldType).

@mmarchini for LTS lines it should be left to backporters to land. I've gone ahead and rebase the PR against the 12.x-staging branch as we just updated to 7.8

mmarchini · 2020-01-13T19:01:17Z

@MylesBorins there is a small conflict on common.gypi, do you mind if I rebase to fix it, or do you want to do it?

MylesBorins · 2020-01-14T01:02:04Z

Go for it!
