This is a quick tool that I've been using to build benchmarking builds
for Deno.
Usage:
Build a benchmark `HEAD~1` and `origin/main` executable:
```sh
deno run tools/build_bench.ts HEAD~1 origin/main
```
Build debug benchmark executables of the last three commits:
```sh
deno run tools/build_bench.ts --profile debug HEAD HEAD~1 HEAD~2
```
Adds an import map of the core and ext JavaScript files. This was
created manually but a script to create one automatically wouldn't be
too much of a big thing either.
This should make working on especially the Node polyfills much more
pleasant, as it gives you feedback on if your imports are correct.
Unfortunately the TypeScript declaration files of some of the internal
modules clash with the import map and override the data from the actual
files with data from the declaration files. Those do not contain all
exports nor is their data always up to date. Still, this is much better
than not having one.
Follow up to https://github.com/denoland/deno/pull/19084.
This commit adds support for globs in the configuration file as well
as CLI arguments for files.
With this change users can now use glob syntax for "include" and
"exclude" fields, like so:
```json
{
"lint": {
"include": [
"directory/test*.ts",
"other_dir/"
],
"exclude": [
"other_dir/foo*.ts",
"nested/nested2/*"
]
},
"test": {
"include": [
"data/test*.ts",
"nested/",
"tests/test[1-9].ts"
],
"exclude": [
"nested/foo?.ts",
"nested/nested2/*"
]
}
}
```
Or in CLI args like so:
```
// notice quotes here; these values will be passed to Deno verbatim
// and deno will perform glob expansion
$ deno fmt --ignore="data/*.ts"
$ deno lint "data/**/*.ts"
```

This commit reimplements most of "node:http" client APIs using
"ext/fetch".
There is some duplicated code and two removed Node compat tests that
will be fixed in follow up PRs.

Partially supersedes #19016.
This migrates `spawn` and `spawn_blocking` to `deno_core`, and removes
the requirement for `spawn` tasks to be `Send` given our single-threaded
executor.
While we don't need to technically do anything w/`spawn_blocking`, this
allows us to have a single `JoinHandle` type that works for both cases,
and allows us to more easily experiment with alternative
`spawn_blocking` implementations that do not require tokio (ie: rayon).

This speeds up WPT tests in two ways:
1. The `WebCryptoAPI` tests are slow, so create a parallel bucket for
each individual test instead of one for all the `WebCryptoAPI` tests.
2. If a test is expected to fail, use a shorter timeout (1 minute rather
than 4).
To make it easier to debug which tests are slowing us down.
Tests taking more than 5s have duration printed in red,
taking more than 1s in yellow and less than 1s are printed
without color.
This reverts commit a3529d0232.
This change made debugging Node tests very hard - `AssertionError` is
now printed as `[Circular *1]` giving no visibility what failed.
We need to align two implementations together and remove this one then.
This reverts commit 4c2269d64a.
> This update introduced more flakiness to the tests on CI, we are going

No need for two almost identical implementations of the same thing

This reverts commit 29fb7709ed.
This update introduced more flakiness to the tests on CI, we are going
to investigate and reland this update after Deno 1.32.0 is released.
This PR _**temporarily**_ removes WebGPU (which has behind the
`--unstable` flag in Deno), due to performance complications due to its
presence.
It will be brought back in the future; as a point of reference, Chrome
will ship WebGPU to stable on 26/04/2023.

This commit renames "deno_core::InternalModuleLoader" to
"ExtModuleLoader" and changes the specifiers used by the
modules loaded from this loader to "ext:".
"internal:" scheme was really ambiguous and it's more characters than
"ext:", which should result in slightly smaller snapshot size.
Closes https://github.com/denoland/deno/issues/18020
- relands #17872
- updates the timeouts to be re-configurable just for CI
- fixes `./tools/wpt.ts update`
- adds option not "ignore" during, applied to wpt epoch runs only
Adds two test files: "cli/tests/unit_node/process_test.ts" and
"cli/tests/unit_node/child_process_test.ts"

This PR refactors all internal js files (except core) to be written as
ES modules.
`__bootstrap`has been mostly replaced with static imports in form in
`internal:[path to file from repo root]`.
To specify if files are ESM, an `esm` method has been added to
`Extension`, similar to the `js` method.
A new ModuleLoader called `InternalModuleLoader` has been added to
enable the loading of internal specifiers, which is used in all
situations except when a snapshot is only loaded, and not a new one is
created from it.

The 1.30.1 release had a performance regression that would have been
caught by looking at the benchmarks page. This adds a pre-flight step to
the release checklist for the person doing the release to go to this
page and look at the output.
This would have prevented #17629
This commit removes "Deno.core" namespace. It is strictly private API
that has no stability guarantees, we were supposed to remove it long time ago.

Updated third_party dlint to v0.37.0 for GitHub Actions. This PR
includes following changes:
* fix(prefer-primordials): Stop using array pattern assignments
* fix(prefer-primordials): Stop using global intrinsics except for
`SharedArrayBuffer`
* feat(guard-for-in): Apply new guard-for-in rule
Previously the inner request object of the original and the new request
were the same, causing the requests to be entangled and mutable changes
to one to be visible to the other. This fixes that.
Since "Deno.spawn()", "Deno.spawnSync()" and "Deno.spawnChild"
are getting deprecated, this commits rewrites all tests and utilities to
use "Deno.Command" API instead.
Implements fast scheduling of deferred op futures.
```rs
#[op(fast)]
async fn op_read(
state: Rc<RefCell<OpState>>,
rid: ResourceId,
buf: &mut [u8],
) -> Result<u32, Error> {
// ...
}
```
The future is scheduled via a fast API call and polled by the event loop
after being woken up by its waker.
