I'm unsure why we canonicalize the config file path when loading and the
canonicalization is causing issues in #19431 because everything in the
lsp is not canonicalized except the config file (actually, the config
file is only canonicalized when auto-discovered and not whens pecified).
We also don't canonicalize module paths when loading them.
Canonicalization was added in https://github.com/denoland/deno/pull/7621
This allows easily using a symlinked temporary directory, which is
useful for debugging issues locally that happen on the CI with a
symlinked temporary directory. For example:
```rs
let context = TestContextBuilder::new()
.use_temp_cwd()
.use_symlinked_temp_dir() // add this
.build();
```
This commit adds ability to print metrics of the Tokio
runtime to the console by passing "DENO_TOKIO_METRICS=1"
env var.
Metrics will be printed every second, but this can be changed
by "DENO_TOKIO_METRICS_INTERVAL=500" env var.
Reduce the GC pressure from the websocket event method by splitting it
into an event getter and a buffer getter.

This switches syscall used in HTTP and WS server from "writev"
to "sendto".
"DENO_USE_WRITEV=1" can be used to enable using "writev" syscall.
Doing this for easier testing of various setups.
This commit migrates "deno_core" from using "FuturesUnordered" to
"tokio::task::JoinSet". This makes every op to be a separate Tokio task
and should unlock better utilization of kqueue/epoll.
There were two quirks added to this PR:
- because of the fact that "JoinSet" immediately polls spawn tasks,
op sanitizers can give false positives in some cases, this was
alleviated by polling event loop once before running a test with
"deno test", which gives canceled ops an opportunity to settle
- "JsRuntimeState::waker" was moved to "OpState::waker" so that FFI
API can still use threadsafe functions - without this change the
registered wakers were wrong as they would not wake up the
whole "JsRuntime" but the task associated with an op

Using `deopt-explorer` I found that a bunch of fields on `WebSocket`
class were polymorphic.
Fortunately it was enough to initialize them to `undefined`
to fix the problem.
This is a quick tool that I've been using to build benchmarking builds
for Deno.
Usage:
Build a benchmark `HEAD~1` and `origin/main` executable:
```sh
deno run tools/build_bench.ts HEAD~1 origin/main
```
Build debug benchmark executables of the last three commits:
```sh
deno run tools/build_bench.ts --profile debug HEAD HEAD~1 HEAD~2
```
No need to go through the async machinery for `send(String | Buffer)` --
we can fire and forget, and then route any send errors into the async
call we're already making (`op_ws_next_event`).
Early benchmark on MacOS:

After: 166.2k msg/sec (+6.6%)

This commit adds basic support for "node:http2" module. Not
all APIs have been yet implemented, but this change already
allows to use this module for some basic functions.
The "grpc" package is still not working, but it's a good stepping
stone.

## WHY
ref: https://github.com/denoland/deno/issues/19165
The FileHandle class has many missing methods compared to node.
Add these.
## WHAT
- Add close method

In case you would consider including specific implementations and not
only build fixes, here's the implementation of the ```rss()``` function
for OpenBSD.
Related issue: https://github.com/denoland/deno/issues/19358.
This is a regression that seems to have been introduced in
https://github.com/denoland/deno/pull/18905. It looks to have been a
performance optimization.
The issue is probably easiest described with some code:
```ts
const target = new EventTarget();
const event = new Event("foo");
target.addEventListener("foo", () => {
console.log('base');
target.addEventListener("foo", () => {
console.log('nested');
});
});
target.dispatchEvent(event);
```
Essentially, the second event listener is being attached while the `foo`
event is still being dispatched. It should then not fire that second
event listener, but Deno currently does.
`rusqlite` does not support async operations; with this PR SQLite
operations will run through `spawn_blocking` to ensure that the event
loop does not get blocked.
There is still only a single SQLite connection. So all operations will
do an async wait on the connection. In the future we can add a
connection pool if needed.
This PR attempts to resolve the first item on the list from
https://github.com/denoland/deno/issues/19330 which is about using a
flat list of interleaved key/value pairs, instead of a nested array of
tuples.
I can tackle some more if you can provide a quick example of using raw
v8 arrays, cc @mmastrac

Internally, `node-tap` spawns a child process with `stdio: [0, 1, 2]`.
Whilst we don't support passing fd numbers as an argument so far, it
turns out that `[0, 1, 2]` is equivalent to `"inherit"` which we already
support. See: https://nodejs.org/api/child_process.html#optionsstdio
Mapping it to `"inherit"` is fine for us and gets us one step closer in
getting `node-tap` working. I'm now at the stage where already the
coverage table is shown 🎉
