```js
Deno.serve(async (req) => {

Closes https://github.com/denoland/deno/issues/21653
|
|
Aligns the error messages in the ext/http and a few messages in the
ext/fetch folder to be in-line with the Deno style guide.
This change-set also removes some unnecessary checks in the 00_serve.ts.
These options were recently removed, so it doesn't make sense to check
for them anymore.

This is a primordialization effort to improve resistance against users
tampering with the global `Object` prototype.

This correctly creates the `AbortSignal` regardless of when we request
it. If the signal is requested after the request has completed, the
signal is created in the aborted state.
Using GC counts, we can see a reduction in object creation:

Max rps without a signal is unchanged, however we can drastically reduce
memory usage by not creating the signal until needed, and we can
optimize the rps in the case where the signal is created.
With a quick memory benchmark, it looks like this helps pretty
drastically with # of GCs when benchmarking w/wrk:

Since both "call" and "execute" were used in error messages, I replaced them with "execute," which is more used.

This commit refactors how we access "core", "internals" and
"primordials" objects coming from `deno_core`, in our internal JavaScript code.
Instead of capturing them from "globalThis.__bootstrap" namespace, we
import them from recently added "ext:core/mod.js" file.

This PR optimizes `fromInner*` methods of `Request` / `Header` /
`Response` used by `Deno.serve` and `fetch` by using `new` instead of
`ObjectCreate` from `createBranded`.
The "brand" is created by passing `webidl.brand` to the constructor
instead.

### Benchmark
```js
const createBranded = Symbol("create branded");
const brand = Symbol("brand");
class B {
constructor(init) {
if (init === createBranded) {
this[brand] = brand;
}
}
}
Deno.bench("Object.create(protoype)", () => {
Object.create(B.prototype);
});
Deno.bench("new Class", () => {
new B(createBranded);
});

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.

This PR fixes #19818. The problem was that the new InnerRequest class does not initialize the fields urlList and urlListProcessed that are used during a request clone. The solution aims to be straightforward by simply initializing the missing properties during the clone process. I also implemented a "cache" to the url getter of the new InnerRequest, avoiding the cost of calling op_http_get_request_method_and_url.

Creating these options bags is more costly than passing arguments
one-by-one. Especially since `prefix` and `context` are passed to all functions.
|
|
This should produce a little less garbage and using an object here
wasn't really required.

Follow up to https://github.com/denoland/deno/pull/18578
We will need to do another pass cleaning up `ext/fetch/23_request.js`
|

for snapshotted modules (#18041)
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

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.

Yearly tradition of creating extra noise in git.
|
|
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.

USVString for Response constructor (#12201)

* perf(ext/fetch): skip USVString webidl conv on string constructor
* Rename webidl convert to RequestInfo_DOMString
To disambiguate and hint that it normalizes to DOMString instead of USVString since DOMString => USVString is handled by `op_url_parse` when calling `new URL(...)`
|
|
In the spec, a URL record has an associated "blob URL entry", which for
`blob:` URLs is populated during parsing to contain a reference to the
`Blob` object that backs that object URL. It is this blob URL entry that
the `fetch` API uses to resolve an object URL.
Therefore, since the `Request` constructor parses URL inputs, it will
have an associated blob URL entry which will be used when fetching, even
if the object URL has been revoked since the construction of the
`Request` object. (The `Request` constructor takes the URL as a string
and parses it, so the object URL must be live at the time it is called.)
This PR adds a new `blobFromObjectUrl` JS function (backed by a new
`op_blob_from_object_url` op) that, if the URL is a valid object URL,
returns a new `Blob` object whose parts are references to the same Rust
`BlobPart`s used by the original `Blob` object. It uses this function to
add a new `blobUrlEntry` field to inner requests, which will be `null`
or such a `Blob`, and then uses `Blob.prototype.stream()` as the
response's body. As a result of this, the `blob:` URL resolution from
`op_fetch` is now useless, and has been removed.
