src: add kNoBrowserGlobals flag for Environment #40532

zcbenz · 2021-10-20T09:52:02Z

This is the runtime equivalent of the configure --no-browser-globals build flag.

A runtime flag is needed because embedders can have multiple modes that, Node.js may both run in a browser environment, and in an independent environment that has no browser globals. For example, Node.js script running in web page spawning a script with child_process.fork.

This PR also moves the creation of browser globals into a separate script, so it can be controlled with C++ flag without affecting bootstrapping in snapshot.

Should this be backported to v17.x-staging? If yes please follow the guide and raise a backport PR, if not let me know or add the dont-land-on label.
There is a conflict because of previous semver-major changes.

zcbenz · 2022-01-17T11:00:06Z

We don't need this backported to 17 in Electron.

danielleadams · 2022-01-31T04:50:53Z

@zcbenz this does not land cleanly in v16.x-staging. Do you mind creating a backport PR?

targos · 2022-01-31T05:59:48Z

@danielleadams this didn't land on v17.x. I'm surprised it shows up in your branch diff

I wonder if that's potentially due to nodejs/branch-diff#45?
