Adds a `parallel` flag to `deno serve`. When present, we spawn multiple
workers to parallelize serving requests.
```bash
deno serve --parallel main.ts
```
Currently on linux we use `SO_REUSEPORT` and rely on the fact that the
kernel will distribute connections in a round-robin manner.
On mac and windows, we sort of emulate this by cloning the underlying
file descriptor and passing a handle to each worker. The connections
will not be guaranteed to be fairly distributed (and in practice almost
certainly won't be), but the distribution is still spread enough to
provide a significant performance increase.

This commit updates Deno to use `reqwest` at 0.12.4
and `rustls` at 0.22. Other related crates were updated
as well to match versions accepted by `reqwest` and `rustls`.
Note: we are not using the latest available `rustls` yet,
but this upgrade was non-trivial already, so a bump to
0.23 for `rustls` will be done in a separate commit.
Closes #23370

Precursor to #23236
This implements the SNI features, but uses private symbols to avoid
exposing the functionality at this time. Note that to properly test this
feature, we need to add a way for `connectTls` to specify a hostname.
This is something that should be pushed into that API at a later time as
well.
```ts
Deno.test(
{ permissions: { net: true, read: true } },
async function listenResolver() {
let sniRequests = [];
const listener = Deno.listenTls({
hostname: "localhost",
port: 0,
[resolverSymbol]: (sni: string) => {
sniRequests.push(sni);
return {
cert,
key,
};
},
});
{
const conn = await Deno.connectTls({
hostname: "localhost",
[serverNameSymbol]: "server-1",
port: listener.addr.port,
});
const [_handshake, serverConn] = await Promise.all([
conn.handshake(),
listener.accept(),
]);
conn.close();
serverConn.close();
}
{
const conn = await Deno.connectTls({
hostname: "localhost",
[serverNameSymbol]: "server-2",
port: listener.addr.port,
});
const [_handshake, serverConn] = await Promise.all([
conn.handshake(),
listener.accept(),
]);
conn.close();
serverConn.close();
}
assertEquals(sniRequests, ["server-1", "server-2"]);
listener.close();
},
);

Fixes #21121 and #19498
Migrates fully to rustls_tokio_stream. We no longer need to maintain our
own TlsStream implementation to properly support duplex.
This should fix a number of errors with TLS and websockets, HTTP and
"other" places where it's failing.
Implements `WebSocket` over http/2. This requires a conformant http/2
server supporting the extended connect protocol.
Passes approximately 100 new WPT tests (mostly `?wpt_flags=h2` versions
of existing websockets APIs).
This is implemented as a fallback when http/1.1 fails, so a server that
supports both h1 and h2 WebSockets will still end up on the http/1.1
upgrade path.
The patch also cleas up the websockets handshake to split it up into
http, https+http1 and https+http2, making it a little less intertwined.
This uncovered a likely bug in the WPT test server:
https://github.com/web-platform-tests/wpt/issues/42896
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

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 is a rewrite of the `Deno.serve` API to live on top of hyper
1.0-rc3. The code should be more maintainable long-term, and avoids some
of the slower mpsc patterns that made the older code less efficient than
it could have been.
Missing features:
- `upgradeHttp` and `upgradeHttpRaw` (`upgradeWebSocket` is available,
however).
- Automatic compression is unavailable on responses.
This implements two macros to simplify extension registration and centralize a lot of the boilerplate as a base for future improvements:
* `deno_core::ops!` registers a block of `#[op]`s, optionally with type
parameters, useful for places where we share lists of ops
* `deno_core::extension!` is used to register an extension, and creates
two methods that can be used at runtime/snapshot generation time:
`init_ops` and `init_ops_and_esm`.

Previously `op_net_listen`, `op_net_accept`, and various other ops in
ext/net where variadic on the transport. This created a lot of code
bloat. This commit updates the code to instead have separate ops for
each transport.
This commit removes the calls to `expect()` on `std::rc::Rc`, which caused
Deno to panic under certain situations. We now return an error if `Rc`
is referenced by other variables.

This commit introduces two new buffer wrapper types to `deno_core`. The
main benefit of these new wrappers is that they can wrap a number of
different underlying buffer types. This allows for a more flexible read
and write API on resources that will require less copying of data
between different buffer representations.
- `BufView` is a read-only view onto a buffer. It can be backed by
`ZeroCopyBuf`, `Vec<u8>`, and `bytes::Bytes`.
- `BufViewMut` is a read-write view onto a buffer. It can be cheaply
converted into a `BufView`. It can be backed by `ZeroCopyBuf` or
`Vec<u8>`.
Both new buffer views have a cursor. This means that the start point of
the view can be constrained to write / read from just a slice of the
view. Only the start point of the slice can be adjusted. The end point
is fixed. To adjust the end point, the underlying buffer needs to be
truncated.
Readable resources have been changed to better cater to resources that
do not support BYOB reads. The basic `read` method now returns a
`BufView` instead of taking a `ZeroCopyBuf` to fill. This allows the
operation to return buffers that the resource has already allocated,
instead of forcing the caller to allocate the buffer. BYOB reads are
still very useful for resources that support them, so a new `read_byob`
method has been added that takes a `BufViewMut` to fill. `op_read`
attempts to use `read_byob` if the resource supports it, which falls
back to `read` and performs an additional copy if it does not. For
Rust->JS reads this change should have no impact, but for Rust->Rust
reads, this allows the caller to avoid an additional copy in many
scenarios. This combined with the support for `BufView` to be backed by
`bytes::Bytes` allows us to avoid one data copy when piping from a
`fetch` response into an `ext/http` response.
Writable resources have been changed to take a `BufView` instead of a
`ZeroCopyBuf` as an argument. This allows for less copying of data in
certain scenarios, as described above. Additionally a new
`Resource::write_all` method has been added that takes a `BufView` and
continually attempts to write the resource until the entire buffer has
been written. Certain resources like files can override this method to
provide a more efficient `write_all` implementation.
This commit adds "Deno.upgradeHttp" API, which
allows to "hijack" connection and switch protocols, to eg.
implement WebSocket required for Node compat.
