WebAssembly modules compiled through `WebAssembly.compile()` and similar
non-streaming APIs don't have a URL associated to them, because they
have been compiled from a buffer source. In stack traces, V8 will use
a URL such as `wasm://wasm/d1c677ea`, with a hash of the module.
However, wasm modules compiled through streaming APIs, like
`WebAssembly.compileStreaming()`, do have a known URL, which can be
obtained from the `Response` object passed into the streaming APIs. And
as per the developer-facing display conventions in the WebAssembly
Web API spec, this URL should be used in stack traces. This change
implements that.

These are confusing. They say they are "for users that don't care about
permissions", but that isn't correct. `NoTimersPermissions` disables
permissions instead of enabling them.
I would argue that implementors should decide what permissions they want
themselves, and not take our opinionated permissions struct.

Reduces self-time by ~70x (~70ms => ~1ms on 1M iters)
for...in filtered by hasOwnProperty yields the same set of keys as Object.keys()
|
|
Use a regex substring match with a first/last char fastpath instead of 2 regex replaces. Roughly ~400x faster (423ms vs 0.7ms in profiled runs)
|
|
This adds support for using in memory CA certificates for
`Deno.startTLS`, `Deno.connectTLS` and `Deno.createHttpClient`.
`certFile` is deprecated in `startTls` and `connectTls`, and removed
from `Deno.createHttpClient`.

Avoid "blob:" prefix check on requests built in the http module since those can never be blob objects
Reduces cost of `newInnerRequest()` from 20ms to 0.1ms in my profiled run on ~2.5M reqs
|
|
Similar to #12235

Not useful to have the defaults externally defined when they're only used in `newInnerResponse()`. Also match order in `newInnerResponse()` and `cloneInnerResponse`
|
|
Avoid initializers due to overhead
|
|
Use a single regex to check for `\0`, `\n`, `\r` instead of 3 `String.includes(...)` calls

* 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(...)`
|
|
|
|
Since those inputs are passed to `new Request(...)` which applies webidl converters

Async WebAssembly compilation was implemented by adding two
bindings: `set_wasm_streaming_callback`, which registered a callback to
be called whenever a streaming wasm compilation was started, and
`wasm_streaming_feed`, which let the JS callback modify the state of the
v8 wasm compiler.
`set_wasm_streaming_callback` cannot currently be implemented as
anything other than a binding, but `wasm_streaming_feed` does not really
need to use anything specific to bindings, and could indeed be
implemented as one or more ops. This PR does that, resulting in a
simplification of the relevant code.
There are three operations on the state of the v8 wasm compiler that
`wasm_streaming_feed` allowed: feeding new bytes into the compiler,
letting it know that there are no more bytes coming from the network,
and aborting the compilation. This PR provides `op_wasm_streaming_feed`
to feed new bytes into the compiler, and `op_wasm_streaming_abort` to
abort the compilation. It doesn't provide an op to let v8 know that the
response is finished, but closing the resource with `Deno.core.close()`
will achieve that.

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.

This commit adds support for specifying client certificates when using fetch, by means of `Deno.createHttpClient`.

The streaming WASM support code inspects the Response object's
Content-Type header but if that was missing, it failed with a fairly
inscrutable "String.prototype.toLowerCase called on null or undefined"
exception. Now it raises a more legible "Invalid WebAssembly content
type" exception.

Don't use `Deno.core`, it's not present in embedders that don't expose
the Deno global object.

This commit implements classic workers, but only when the `--enable-testing-features-do-not-use` flag is provided. This change is not user facing. Classic workers are used extensively in WPT tests. The classic workers do not support loading from disk, and do not support TypeScript.

Instead of relying on callers to map Options to Results via `.ok_or_else(bad_resource_id)` at over 176 different call sites ...
