[8.x] deps: V8: backport 49712d8a from upstream by ofrobots · Pull Request #21334 · nodejs/node

Original commit message:

[wasm] Call AsyncInstantiate directly when instantiating a module object

WebAssembly.instantiate is polymorphic, it can either take a module
object as parameter, or a buffer source which should be compiled first.
To share code between the two implementations, the module object was
first passed to a promise (i.e. which is the result of compilation).
However, passing the module object to a promise has a side effect if
the module object has a then function. To avoid this side effect I
remove this code sharing and call AsyncInstantiate directly in case
the parameter is a module object.

This effects 9.x as well, but I expect it is not worthwhile fixing there at this point.

Seems like some merge conflicts sneaked in.

Yikes. Fixed.

ofrobots · 2018-06-18T19:06:52Z

Fixed the merge conflict. This didn't land cleanly on 8.x and tweaks were necessary. Changed title from cherry-pick to a backport.

@nodejs/build @mhdawson the V8-CI seems to be hitting infra issues AFAICT. Any ideas?

mmarchini · 2018-06-18T22:42:28Z

make test-v8 works on my machine, confirming this is an infra issue. But let's do another run, just in case:

https://ci.nodejs.org/job/node-test-commit-v8-linux/1442/

ofrobots · 2018-06-19T14:39:27Z

@mhdawson @nodejs/build ping. Several V8 back-port are blocked because of this.

mmarchini · 2018-06-19T16:57:51Z

It's not happening on all V8 backports though. Maybe it's only happening to v8.x backports?

richardlau · 2018-06-19T18:13:07Z

It's not happening on all V8 backports though. Maybe it's only happening to v8.x backports?

The compiler level used on LinuxOne (s390x), ppcle Linux and AIX is based on the version of Node.js (i.e., >9): https://github.com/nodejs/build/blob/master/jenkins/scripts/select-compiler.sh

mhdawson · 2018-06-19T20:47:42Z

There seem to be a few issues. I fixed IBM platform specific ones related to changes made to build with GN. But those were not what was reported here.

opened nodejs/build#1370 as it seems to fail for other reasons on x86 for 10.x

mhdawson · 2018-06-19T20:51:09Z

It seems to fail on V8.x without any other changes, @mmarchini confirmed it fails the same for V8.x-staging.

mhdawson · 2018-06-19T20:57:03Z

Cleaned the workspace, if that still fails then my next guess is that something landed in v8.x v8.x-staging which broke it. Run on v8.x after cleaning workspace: https://ci.nodejs.org/job/node-test-commit-v8-linux/1456/

mhdawson · 2018-06-19T21:00:51Z

@richardlau I don't know what you are trying to point out? It fails across the board for v8.x including x86.

ofrobots · 2018-06-19T21:07:24Z

Relaunched V8-CI: https://ci.nodejs.org/view/All/job/node-test-commit-v8-linux/1457/

mhdawson · 2018-06-19T21:10:21Z

Build to see if it passed on 6.x or not https://ci.nodejs.org/job/node-test-commit-v8-linux/1458/

It still failed on 8.x. If it passes on 6.x then I think its something in the 8.x line. .

ofrobots · 2018-06-19T21:15:31Z

It failed on my PR branch.

Here's a build of the v8.x-staging branch: https://ci.nodejs.org/view/All/job/node-test-commit-v8-linux/1459/.

mhdawson · 2018-06-19T21:24:33Z

Workspace clean then build on 6.x - https://ci.nodejs.org/job/node-test-commit-v8-linux/1460/

richardlau · 2018-06-19T21:26:15Z

@richardlau I don't know what you are trying to point out? It fails across the board for v8.x including x86.

My apologies, I didn't spot that nodes=benchmark was x64.

ofrobots · 2018-06-19T21:29:41Z

All failed.

mhdawson · 2018-06-19T21:34:20Z

Failed for a different reason on 6.x. I'm wondering if it has to do with the google tooling required to build.

@MylesBorins when was the last time these worked on 6.x and 8.x?
@ofrobots can you run 8.x on a linux machine outside the ci to see if its related to the build machine or something else?

ofrobots · 2018-06-19T23:35:38Z

make test-v8 runs fine on my linux machine, and it seems for @mmarchini as per #21334 (comment). This seems like an infra issue.

MylesBorins · 2018-06-20T15:07:41Z

we had V8 ci pass on 8.x-staging recently https://ci.nodejs.org/view/All/job/node-test-commit-v8-linux/1426/

mhdawson · 2018-06-20T19:16:58Z

@mmarchini mentioned his test run was on OSX not linux, so not necessary confirmation one way or the other.

mmarchini · 2018-06-20T20:54:55Z

Same failures while running tests on another CI machine:
https://ci.nodejs.org/job/node-test-commit-v8-linux/1472/nodes=ubuntu1604-intel-64,v8test=v8test/console

I'm working on it, but might take some time to track down and fix this one.

mmarchini · 2018-06-20T22:01:21Z

I was able to reproduce in an Ubuntu 16.04 x64 VM on my computer, so this is definitely not a problem with our infrastructure. Let me see if I can find when this started to happen.

mhdawson · 2018-06-20T22:12:47Z

The other thing I noticed was it looks like the passing builds (10.x and later) use g++ while the failing ones use clang (8.x). Not sure why what would be the case.

Also the failures on ppc and s390 look different, have asked @mmallick-ca to take a look at what might be going on there. Sounds like gclient sync is not pulling in something that is required.

mhdawson · 2018-06-20T22:17:05Z

At this point I'll wait to see what @mmarchini figures out before spending any more time on this.

@nodejs/lts @nodejs/v8-update another ping. This needs an LGTM. A rubber stamp would do.

~~Actually, I was mistaken, these fixes not in 10 just yet. They are in V8 6.8 (rather than 6.7). Let's hold off on landing this until a 10.x release picks them up.~~

Ooops, I intended to add the above to #21558.
