Use the [scopeguard](https://docs.rs/scopeguard/) defer macro to run
cleanup code for `new_slab_future`.
This means it can be a single async function, avoiding the need to
create a struct and implement `PinnedDrop`
Async cleanup in Rust is awkward because async functions may be
cancelled at any await point when their Future is dropped.
The scopeguard approach comes from the following articles:
* [How to think about `async`/`await` in
Rust](http://cliffle.com/blog/async-inversion/)
* [Async Cancellation
I](https://blog.yoshuawuyts.com/async-cancellation-1/) (Reddit
[discussion](https://www.reddit.com/r/rust/comments/qrhg39/blog_post_async_cancellation/))

(#20641)
Builds on top of #20622 to fix #10854
|
|
|
|
|
|
`Array.from` has optional second argument. Calling `map` is not required
for this case.

resourceForReadableStream (#20622)
We can go one level down in abstraction and avoid using the public
`ReadableStream` APIs.
This patch ~5% perf boost on small ReadableStream:

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 introduces an optimization to `set_response` to reduce the
overhead for responses with a payload size less than 64 bytes.
Performance gains are more noticeable when `is_request_compressible`
enters the slow path, ie: `-H 'Accept-Encoding: unknown'`

This commit improves async op sanitizer speed by only delaying metrics
collection if there are pending ops. This
results in a speedup of around 30% for small CPU bound unit tests.
It performs this check and possible delay on every collection now,
fixing an issue with parent test leaks into steps.

This commit adds "deno jupyter" subcommand which
provides a Deno kernel for Jupyter notebooks.
The implementation is mostly based on Deno's REPL and
reuses large parts of it (though there's some clean up that
needs to happen in follow up PRs). Not all functionality of
Jupyter kernel is implemented and some message type
are still not implemented (eg. "inspect_request") but
the kernel is fully working and provides all the capatibilities
that the Deno REPL has; including TypeScript transpilation
and npm packages support.

This commit improves compatibility of "node:http2" module by polyfilling
"connect" method and "ClientHttp2Session" class. Basic operations like
streaming, header and trailer handling are working correctly.
Refing/unrefing is still a TODO and "npm:grpc-js/grpc" is not yet working
correctly.

This PR implements a graceful shutdown API for Deno.serve, allowing all
current connections to drain from the server before shutting down, while
preventing new connections from being started or new transactions on
existing connections from being created.
We split the cancellation handle into two parts: a listener handle, and
a connection handle. A graceful shutdown cancels the listener only,
while allowing the connections to drain. The connection handle aborts
all futures. If the listener handle is cancelled, we put the connections
into graceful shutdown mode, which disables keep-alive on http/1.1 and
uses http/2 mechanisms for http/2 connections.
In addition, we now guarantee that all connections are complete or
cancelled, and all resources are cleaned up when the server `finished`
promise resolves -- we use a Rust-side server refcount for this.
Performance impact: does not appear to affect basic serving performance
by more than 1% (~126k -> ~125k)

Functions should generally be annotated with `#[allow]` blocks rather
than using inner `#![allow]` annotations.

Fixes performance regression introduced by
https://github.com/denoland/deno/pull/20223 and
https://github.com/denoland/deno/pull/20314. It's enough to have one
"shared" buffer per socket
and no locking mechanism is required.

In that issue, I suggest switching over the other brotli functionality
to the Rust API provided by the `brotli` crate. Here, I only do that
with the `brotli_decompress` function to fix the bug with buffers longer
than 4096 bytes.

Extracted from https://github.com/denoland/deno/pull/17815
Optimise Buffer's string operations, most significantly when dealing
with ASCII and UTF-16. Base64 and HEX encodings are affected to much
lesser degrees.
## Performance
### String length 15
With very small strings we're at break-even or sometimes even lose a tad
bit of performance from creating a `DataView` that ends up not paying
for itself.

Keys are expensive metadata. We track it for various purposes, e.g.
transaction conflict check, and key expiration.
This patch limits the total key size in an atomic operation to 80 KiB
(81920 bytes). This helps ensure efficiency in implementations.
