domain, src: clean up domain-related code #18291

apapirovski · 2018-01-22T16:40:26Z

Move the majority of C++ domain-related code into JS land by introducing a top level domain callback which handles entering & exiting the domain.

Move the rest of the domain necessities into their own file that creates an internal binding, to avoid exposing domain-related code on the process object.

Also a bit of other assorted domain-related cleanup.

(This happens to boost the performance of top-level domain code by roughly 33% but mostly I just wanted to have less domain-related code scattered all over.)

Checklist

Ugh, I forgot we support older complier versions. Need to get rid of the variable length array.

Modify an existing test slightly to better test domain-related code.

Fixed up.

Linter failure is not from this PR...

LGTM with a suggestion.

src/node.cc

    }
+    Local<Value> domain_argv[] = { callback, argv_array };
+    ret = domain_cb->Call(env->context(), recv, 2, domain_argv);


It's probably faster to use spread in JS land and skip allocating the JS array here. I.e.:

std::vector<Local<Value>> args(1 + argc); args[0] = callback; std::copy(&argv[0], &argv[argc], &args[1]); ret = domain_cb->Call(env->context(), recv, args.size(), &args[0]);

Then in JS:

function topLevelDomainCallback(cb, ...args) { // ... }

Thanks @bnoordhuis, will update!

Now that linter & inspector tests are fixed.

@AndreasMadsen I would love to have you review this, if possible, as you've headed up most of the effort around the recent changes to domains. Thanks!

this doesn't land cleanly in v9.x, should it be backported?

Should this be backported to v8.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.

If backporting please include #18460
