feat(ext/timers): add refTimer, unrefTimer API (alt)

[kt3k]

depends on #12862 (alternative to #12942)

This PR adds Deno.refTimer and Deno.unrefTimer APIs in the unstable namespace.

---

closes #6141

Needs a rebase but #12862 was merged earlier today and this PR otherwise LGTM.

-       timerInfo = { cancelRid, isRef: true };
+       timerInfo = { cancelRid, isRef: true, promiseId: -1 };

Keeps the object monomorphic.

if (timerInfo === undefined || timerInfo.isRef) { (ditto on line 277)

The id = 0 default argument is kind of weird/footgun-y, I'd remove that.

Oops. Thanks!

The id = 0 default argument is kind of weird/footgun-y, I'd remove that.

I blindly followed the pattern used in clearTimeout/clearInterval, but I agree with your point

[bartlomieju]

LGTM too! Nice work @kt3k

Is there any timeline this might go from unstable to stable? I think this might be the only thing preventing me from being able to push jobs from Deno Deploy to BullMQ

@jcs224 How do you try to use Bull MQ in Deploy? Is it via esm.sh? Do you import https://esm.sh/bullmq?

[jcs224]

I've been using the Node require polyfill, this works fine with the --unstable flag:

import { createRequire } from "https://deno.land/[email protected]/node/module.ts";
const require = createRequire(import.meta.url);

const { Queue } = require('bullmq')

const myQueue = new Queue('foo')

However, when I try this:

import { Queue } from 'https://esm.sh/bullmq'

const myQueue = new Queue('foo')

I get a weird lodash error

error: Uncaught SyntaxError: The requested module '/v78/[email protected]/deno/lodash.js' does not provide an export named 'get' at https://cdn.esm.sh/v78/[email protected]/deno/bullmq.js:7:20803

Also, I've been doing this all with the CLI, not deploy. I know that Deploy only uses stable API so I didn't even bother to try. The node require polyfill should work in Deploy though, right? I should have probably checked that...
