timers: allow timers to be used as primitives #34017

lundibundi · 2020-06-22T14:49:14Z

This allows timers to be matched to numeric Ids and therefore used
as keys of an Object, passed and stored without storing the Timer instance.

clearTimeout/clearInterval is modified to support numeric/string Ids.

Continuing great work of @bmeck and @apapirovski. Noticed this PR, checked the benchmarks and they looked just fine with almost no impact now. See results on my machine below

I've also tried to use Map and it show slightly worse performance for some reason.

I didn't try the holey array as that would require using parseInt on passed strings to get the original number Id and could possibly add unnecessary overhead/unexpected errors to clearTimeout.

Generally seems fine to me, though I think the lack of compatibility with worker_threads will probably decrease its usefulness. I also do not see any good way around that though.

Generally seems fine to me, though I think the lack of compatibility with worker_threads will probably decrease its usefulness. I also do not see any good way around that though.

Hm, I thought a somewhat simple wrapper for setTimeout would suffice to handle that use case.
i.e. Have Map of timerId to some workerId in the main thread, make custom setTimeout that would store\remove ids from Map upon addition/removal of timers (in main tread) and make appropriate calls in sub-threads via messages to the main thread that would then post message for addition/removal to correct thread.
It should be also possible to make that peer-to-peer where each thread handles local timers and makes broadcasts to other threads and probably uses some cache of timer-to-worker to avoid unnecessary broadcasts.

There are multiple options and trade-offs to make while implementing that so I'd not do it in core unless we find a nice way to connect async_hooks with worker_threads.

Benchmark CI results are kind of weird (11% improvement of timers/timers-timeout-nexttick.js for no reason) but not too bad.

@lundibundi This needs a rebase.

This allows timers to be matched to numeric Ids and therefore used as keys of an Object, passed and stored without storing the Timer instance. clearTimeout/clearInterval is modified to support numeric/string Ids.
