Original commit message:

    [build] Introduce an embedder version string

    Sometimes, the embedder might want to merge a fix to an abandoned branch
    or to a supported branch but the fix is not relevant to Chromium.
    This adds a new version string that the embedder can set at compile time
    and that will be appended to the official V8 version.
    The separator must be provided in the string. For instance, to have a
    full version string like "6.0.287.53-emb.1", the embedder must set
    V8_EMBEDDER_STRING to "-emb.1".

@targos targos added build Issues and PRs related to build files or the CI. semver-major PRs that contain breaking changes and should be released in the next major version. labels Oct 5, 2017
@nodejs-github-bot nodejs-github-bot added the lib / src Issues and PRs related to general changes in the lib or src directory. label Oct 5, 2017
After this commit, `process.versions.v8` will look like:
"6.0.287.53-node.0".
The goal is that everytime we apply a non-official patch to `deps/v8`,
we increment our own number instead of V8's patch level.
This number must be set back to 0 after major V8 updates.

Closes: nodejs#15698

Should the guide be updated?

@gibfahn you are right. I hope to have some time during the collab summit to work on that (and submit another PR) because I think this guide needs more in-depth changes.

I think this guide needs more in-depth changes.

I'm sure you're right, and please do rewrite, but for this PR I think you can just change this line:

Increase the patch level version in v8-version.h. This will not cause any problems with versioning because V8 will not publish other patches for this branch, so Node.js can effectively bump the patch version.

Similar to #16053 (comment), should the cherry-pick be requested for backport to V8 6.1 in V8?

targos commented Oct 6, 2017

We can try but this change is not a bug fix, so a backmerge would probably be rejected

@targos targos added this to the 9.0.0 milestone Oct 7, 2017

@targos is this landed in 6.2?

No. 6.3.

@hashseed is it too late to request a backport to 6.2?

@natorion what's your take on this? This change is not a bug fix. Then again it would not affect Chromium. Can we backport this?
