Embedders may not want to terminate the process when process.exit()
is called. This provides a hook for more flexible handling of that
situation.

no doc update?

@himself65 The documentation for our public C++ API is provided as comments in node.h – that’s the customary way of documenting C++ APIs. We have an embedding doc now, but that’s mostly there to provide an example, and also links to node.h for more information.

isn't this an un-necessary call for workers?

@gireeshpunathil So … no, but thanks for pointing this out.

My line of thinking here was “both the main thread and Workers perform this call anyway, so why not do it at the same time so that behavior is more similar and therefore less prone to bugs”.

While that was not wrong, it introduced a bug that I wouldn’t have noticed if you hadn’t commented; Because this happens without setting can_call_into_js() to false, the Workers are stopped and their exit events would be emitted. We generally don’t want asynchronous resources to emit events during process.exit(), so that’s a bug.

The change here meant that this bug would also occur when running nested Workers, but on the main thread, it has been present before. I’ve opened #32546 fixes that (and this PR is rebased on top of it), and marked this PR as blocked until that one lands, because this is semver-minor and the other PR is semver-patch, and our tooling doesn’t like mixing them.

I’ve also added a commit here that makes Stop(env) stop Worker threads – that seems like a sensible thing to do, and achieves my original goal of being more consistent between Worker threads and the main thread.

called when process.exit() is called from JS. might make some users think that the callback in invoked after the default process.exit has been actioned?

called in response to process.exit() call from JS. may be a better wording?

called when process.exit() is called from JS. might make some users think that the callback in invoked after the default process.exit has been actioned?

The default process.exit() terminates the process, which by definition precludes any other code from being run afterwards, so I don’t think that that is a very likely reading of this phrasing (or at least one that would appear self-contradictory).

called in response to process.exit() call from JS. may be a better wording?

I’d be worried that that makes it sound like an asynchronous call, when it is really called during process.exit() itself.

I’ve added wording that explicitly specifies that this overrides the default handler, I hope that helps.

Refs: nodejs#30467 (comment)
This makes sense given that terminating execution of the parent thread
this way likely also is supposed to stop all running Worker threads
spawned by it.

addaleax added a commit that referenced this pull request Feb 18, 2021
This reverts commit 037ac99.

As flaky CI failures have revealed, this feature was implemented
incorrectly. `stop_sub_worker_contexts()` needs to be called on the
thread on which the `Environment` is currently running, it’s not
thread-safe. The current API requires `Stop()` to be thread-safe,
though.

We could add a new API for this, but unless there’s demand, that’s
probably not necessary as `FreeEnvironment()` will also stop Workers,
which is commonly the next action on an `Environment` instance after
having `Stop()` called on it.
