4e08665973 perf(ext/request): optimize validate and normalize HTTP method (#20143)
This PR optimizes `Request` constructor init method step. It doubles the
speed for known lowercased methods. I also added `PATCH` to known
methods

d0525dd692 perf(ext/headers): use regex.test instead of .exec (#20125)
This PR improves the performance of `Headers.get` by using `Regex.test`
instead of `.exec`. Also replaced the `Map` used for caching with an
object which is a bit faster

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.

1a1283fa4d perf(ext/http): use ServeHandlerInfo class instead of object literal (#20122)
This PR improves performance of `Deno.Serve` when providing `info`
argument by creating `ServeHandlerInfo` class instead of creating an
object literal with a getter on every request.

```js
Deno.serve((_req, info) => new Response(info.remoteAddr.transport) });
```

### 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.

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: remove redundant rerun-if-changed for compiler snapshot (#20094)
Not sure why `40_testing.js` is there. The other two `00_typescript.js`
and `99_main_compiler.js` should be covered by
`files_loaded_during_snapshot` at the end.

This helps with `__runtime_js_sources` wrt changing `40_testing.js`.

feat(unstable): rename deno_modules to vendor (#20065)
Renames the unstable `deno_modules` directory and corresponding settings
to `vendor` after feedback. Also causes the vendoring of the
`node_modules` directory which can be disabled via
`--node-modules-dir=false` or `"nodeModulesDir": false`.

fix(unstable): vendor cache should support adding files to hashed directories (#20070)
This changes the design of the manifest.json file to have a separate
"folders" map for mapping hashed directories. This allows, for example,
to add files in a folder like `http_localhost_8000/#testing_5de71/` and
have them be resolved automatically as long as their remaining
components are identity-mappable to the file system (not hashed). It
also saves space in the manifest.json file by only including the hashed
directory instead of each descendant file.

```
// manifest.json
{
  "folders": {
    "https://localhost/NOT_MAPPABLE/": "localhost/#not_mappable_5cefgh"
  },
  "modules": {
    "https://localhost/folder/file": {
      "headers": {
        "content-type": "application/javascript"
      }
    },
  }
}

// folder structure
localhost
  - folder
    - #file_2defn (note: I've made up the hashes in these examples)
  - #not_mappable_5cefgh
    - mod.ts
    - etc.ts
    - more_files.ts
```

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/file): resolve unresolved Promise in Blob.stream (#20039)
This PR fixes some crashing WPT tests due to an unresolved promise.

---
This could be a [stream spec](https://streams.spec.whatwg.org) bug

When `controller.close` is called on a byob stream, there's no cleanup
of pending `readIntoRequests`. The only cleanup of pending
`readIntoRequests` happen when `.byobRequest.respond(0)` is called, it
happens
here:6ba245fe25/ext/web/06_streams.js (L2026)
which ends up calling `readIntoRequest.closeSteps(chunk);` in
6ba245fe25/ext/web/06_streams.js (L2070)



To reproduce:

```js
async function byobRead() {
  const input = [new Uint8Array([8, 241, 48, 123, 151])];
  const stream = new ReadableStream({
    type: "bytes",
    async pull(controller) {
      if(input.length === 0) {
        controller.close();
        // controller.byobRequest.respond(0); // uncomment for fix 
        return 
      }
      controller.enqueue(input.shift())
    },
  });

  const reader = stream.getReader({ mode: 'byob' });
  const r1 = await reader.read(new Uint8Array(64));
  console.log(r1);
  const r2 = await reader.read(new Uint8Array(64));
  console.log(r2);
}

await byobRead();
```

Running the script triggers:
```
error: Top-level await promise never resolved
```

refactor(ext/fetch): refactor fetch to use new write_error method (#20029)
This is a prerequisite for fast streams work -- this particular resource
used a custom `mpsc`-style stream, and this work will allow us to unify
it with the streams in `ext/http` in time.

Instead of using Option as an internal semaphore for "correctly
completed EOF", we allow code to propagate errors into the channel which
can be picked up by downstream sinks like Hyper. EOF is signalled using
a more standard sender drop.

chore: fix pty support on Macs (#20037)
Many of the CI tests have been failing on my M2 Pro mac (Ventura 13.4)
when running inside of a vscode terminal (a strange `ENOTTY` error).
This modifies the pty-handling code to use libc directly rather than the
older pty library that appears mostly unmaintained (outside of
@littledivy's fork).

As a bonus, this should allow us to run pty tests on the mac CI runner.

After this PR, the tests now complete with 100% success on my local
machine. Before this PR, I needed to pass `CI=true` to get my local test
suite to pass.

feat(permissions): add "--deny-*" flags (#19070)
This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.

These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.

Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.

Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.

Closes #18804.

This commit adds a "dot" reporter to "deno test" subcommand,
that can be activated using "--dot" flag.

It provides a concise output using:
- "." for passing test
- "," for ignored test
- "!" for failing test

User output is silenced and not printed to the console.

In non-TTY environments each result is printed on a separate line.
