fix(test): Improve reliability of deno test's op sanitizer with timers (#12934)
Although not easy to replicate in the wild, the `deno test` op sanitizer
can fail when there are intervals that started before a test runs, since
the op sanitizer can end up running in the time between the timer op for
an interval's run resolves and the op for the next run starts.

This change fixes that by adding a new macrotask callback that will run
after the timer macrotask queue has drained. This ensures that there is
a timer op if there are any timers which are unresolved by the time the
op sanitizer runs.

deno_runtime crate

crates docs

This is a slim version of the Deno CLI which removes typescript integration and various tooling (like lint and doc). Basically only JavaScript execution with Deno's operating system bindings (ops).

Stability

This crate is built using battle-tested modules that were originally in deno crate, however the API of this crate is subject to rapid and breaking changes.

MainWorker

The main API of this crate is MainWorker. MainWorker is a structure encapsulating deno_core::JsRuntime with a set of ops used to implement Deno namespace.

When creating a MainWorker implementors must call MainWorker::bootstrap to prepare JS runtime for use.

MainWorker is highly configurable and allows to customize many of the runtime's properties:

  • module loading implementation
  • error formatting
  • support for source maps
  • support for V8 inspector and Chrome Devtools debugger
  • HTTP client user agent, CA certificate
  • random number generator seed

Worker Web API

deno_runtime comes with support for Worker Web API. The Worker API is implemented using WebWorker structure.

When creating a new instance of MainWorker implementors must provide a callback function that is used when creating a new instance of Worker.

All WebWorker instances are descendents of MainWorker which is responsible for setting up communication with child worker. Each WebWorker spawns a new OS thread that is dedicated solely to that worker.
