431289faaa fix(ext/http): ensure request body resource lives as long as response is alive (#20206) 
Deno.serve's fast streaming implementation was not keeping the request
body resource ID alive. We were taking the `Rc<Resource>` from the
resource table during the response, so a hairpin duplex response that
fed back the request body would work.

However, if any JS code attempted to read from the request body (which
requires the resource ID to be valid), the response would fail with a
difficult-to-diagnose "EOF" error.

This was affecting more complex duplex uses of `Deno.fetch` (though as
far as I can tell was unreported).

Simple test:

```ts
        const reader = request.body.getReader();
        return new Response(
          new ReadableStream({
            async pull(controller) {
              const { done, value } = await reader.read();
              if (done) {
                controller.close();
              } else {
                controller.enqueue(value);
              }
            },
          }),
```

And then attempt to use the stream in duplex mode:

```ts

async function testDuplex(
  reader: ReadableStreamDefaultReader<Uint8Array>,
  writable: WritableStreamDefaultWriter<Uint8Array>,
) {
  await writable.write(new Uint8Array([1]));
  const chunk1 = await reader.read();
  assert(!chunk1.done);
  assertEquals(chunk1.value, new Uint8Array([1]));
  await writable.write(new Uint8Array([2]));
  const chunk2 = await reader.read();
  assert(!chunk2.done);
  assertEquals(chunk2.value, new Uint8Array([2]));
  await writable.close();
  const chunk3 = await reader.read();
  assert(chunk3.done);
}
```

In older versions of Deno, this would just lock up. I believe after
23ff0e722e, it started throwing a more
explicit error:

```
httpServerStreamDuplexJavascript => ./cli/tests/unit/serve_test.ts:1339:6
error: TypeError: request or response body error: error reading a body from connection: Connection reset by peer (os error 54)

32947e5ea5 feat(ext/web): resourceForReadableStream (#20180) 
Extracted from fast streams work.

This is a resource wrapper for `ReadableStream`, allowing us to treat
all `ReadableStream` instances as resources, and remove special paths in
both `fetch` and `serve`.

Performance with a ReadableStream response yields ~18% improvement:

```
  return new Response(new ReadableStream({
    start(controller) {
      controller.enqueue(new Uint8Array([104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]));
      controller.close();
    }
  })
```

3b4efd339d perf(ext/event): optimize Event constructor (#20181) 
This PR optimizes `Event` constructor

- ~Added a fast path for empty `eventInitDict`~ Removed `EventInit`
dictionary converter
- Don't make `isTrusted` a
[LegacyUnforgeable](https://webidl.spec.whatwg.org/#LegacyUnforgeable)
property. Doing so makes it non-spec compliant but calling
`Object/Reflect.defineProperty` on the constructor is a big bottleneck.
Node did the same a few months ago
https://github.com/nodejs/node/pull/46974. In my opinion, the
performance gains are worth deviating from the spec for a
browser-related property.

75ea2c1b20 perf(ext/urlpattern): optimize URLPattern.exec (#20170) 
This PR optimizes `URLPattern.exec` 

- Use component keys from constructor instead of calling it on every
`.exec`. AFAIK keys should always be
`protocol`,`username`,`password`,`hostname`,`port`,`pathname`,`search`,`hash`.
Haven't looked much into it but I think it's safe to define these
outside the constructor as well.
- Add a fast path for `/^$/u` (default regexp) and empty input
- Replaced `ArrayPrototypeMap` & `ObjectFromEntries` with a `for` loop.

occurs when the variables `uid` and `gid` from `userInfo()` in `node:os`

marked as `const` therefore producing a `TypeError` when the two are
reassigned.

851e08bd1f feat(ext/node): eagerly bootstrap node (#20153) 
To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:

 - [x] Process stdin/stdout/stderr are lazily created
 - [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added

4001fad25f fix(ext/net): implement a graceful error on an invalid SSL certificate (#20157) 
The goal of this PR is to address issue #19520 where Deno panics when
encountering an invalid SSL certificate.

This PR achieves that goal by removing an `.expect()` statement and
implementing a match statement on `tsl_config` (found in
[/ext/net/ops_tsl.rs](e071382768/ext/net/ops_tls.rs (L1058)))
to check whether the desired configuration is valid

e77d55839d perf(ext/headers): optimize headers iterable (#20155) 
This PR makes more optimizations to headers iterable by removing
`ObjectEntries` which was consistently prominent in the flame graph when
benchmarking an express server.

aaa3608cc1 perf(ext/headers): cache iterableHeaders for immutable Headers (#20132) 
This PR caches `_iterableHeaders` for immutable `Headers` increasing the
performance of `fetch` & server if headers are iterated.

Should close #19466 

I only cached immutable headers to address this comment
https://github.com/denoland/deno/issues/19466#issuecomment-1589892373
since I didn't find any occurrence of header mutation on immutable
headers. We can discuss caching for non-immutable, but I think this is a
great first step.

## BENCHMARK

### Server
```js
const addr = Deno.args[0] ?? "127.0.0.1:4500";
const [hostname, port] = addr.split(":");
const { serve } = Deno;

serve({ hostname, port: Number(port), reusePort: true }, (req) => {
  const headers = [...req.headers]; // req.headers are immutable, cannot set/append/delete
  return new Response("ok");
});

```
Used `wrk` with 5 headers
```
wrk -d 10s --latency -H "X-Deno: true" -H "Accept: application/json" -H "X-Foo: bar" -H "User-Agent: wrk" -H "Accept-Encoding: gzip, br" http://127.0.0.1:4500

bf9ddb7c2e perf(ext/request): optimize Request constructor (#20141) 
This PR optimizes `Request` constructor when `init` is not empty. This
path is also used by `fetch` when `options` argument is used
```js
fetch("https://deno.land", {
  method: "POST",
  body: 'land'
});
```

- Removed 3 extra calls to `headerListFromHeaders`
- Avoid `Object.keys` & `headerList` clone if `init.headers` is set
- Only empty `headersList` (`.splice`) if it's not already empty.

### Drawbacks:

`.remoteAddr` is now not enumerable

```
ServeHandlerInfo {}
```
vs
```
{ remoteAddr: [Getter] }
```
It'll break any code trying to iterate through `info` keys (Doubt
there's anyone doing it though)

```js
Deno.serve((req, info) => {
  console.log(Object.keys(info).length === 0) // true;
  return new Response("yes");

refactor(ext/cache): Remove custom shutdown and use fast async ops (#20107) 
The original implementation of `Cache` used a custom `shutdown` method
on the resource, but to simplify fast streams work we're going to move
this to an op of its own.

While we're in here, we're going to replace `opAsync` with
`ensureFastOps`. `op2` work will have to wait because of some
limitations to our async support, however.

chore: rename some helpers on the Fs trait (#20097) 
Rename some of the helper methods on the Fs trait to be suffixed with
`_sync` / `_async`, in preparation of the introduction of more async
methods for some helpers.

Also adds a `read_text_file_async` helper to complement the renamed
`read_text_file_sync` helper.

fix(ext/abort): trigger AbortSignal events in correct order (#20095) 
This PR ensures that the original signal event is fired before any
dependent signal events.

---
The enabled tests fail on `main`:

```
assert_array_equals: Abort events fired in correct order expected property 0 to be 
"original-aborted" but got "clone-aborted" (expected array ["original-aborted", "clone-aborted"] 
got ["clone-aborted", "original-aborted"])

build: allow disabling snapshots for dev (#20048) 
Closes #19399 (running without snapshots at all was suggested as an
alternative solution).

Adds a `__runtime_js_sources` pseudo-private feature to load extension
JS sources at runtime for faster development, instead of building and
loading snapshots or embedding sources in the binary. Will only work in
a development environment obviously.

Try running `cargo test --features __runtime_js_sources
integration::node_unit_tests::os_test`. Then break some behaviour in
`ext/node/polyfills/os.ts` e.g. make `function cpus() {}` return an
empty array, and run it again. Fix and then run again. No more build
time in between.

chore(cargo): update async-compression/flate2/miniz to latest (#20049) 
This bumps `async-compression` dependency in `deno_http` to latest, in
order to avoid having multiple duplicate versions.
Related, it also unpin a stale `flate2` dependency so that the whole
chain of `async-compression` -> `flate2` -> `miniz_oxide` can surface up
to current versions.
The lockfile entries for all of the above crates have been update
accordingly; the new tree of dependencies looks like this:
```
$ cargo tree -i -p miniz_oxide

miniz_oxide v0.7.1
└── flate2 v1.0.26
    └── async-compression v0.4.1
```

fix(ext/http): unify default gzip compression level (#20050) 
This tweaks the HTTP response-writer in order to align the two possible
execution flows into using the same gzip default compression level, that
is `1` (otherwise the implicit default level is `6`).
