This commit adds op_read_sync and op_write_sync to core. These ops are
similar to op_read and op_write, but they are synchronous. Just like the
async ops, they operate on generic `deno_core::Resource` objects. These
now have new `read_byob_sync` and `write_sync` methods, with default
implementations throwing "NotSupported" errors, just like the async
counterparts.
There are no `write_all` or `read` equivalents, because the
optimizations they unlock are not useful in synchronous contexts.
This is a follow-on to the earlier work in reducing string copies,
mainly focused on ensuring that ASCII strings are easy to provide to the
JS runtime.
While we are replacing a 16-byte reference in a number of places with a
24-byte structure (measured via `std::mem::size_of`), the reduction in
copies wins out over the additional size of the arguments passed into
functions.
Benchmarking shows approximately the same if not slightly less wallclock
time/instructions retired, but I believe this continues to open up
further refactoring opportunities.
This commit changes "node:http" module to use "Deno.serveHttp" API
instead of "Deno.serve" API.

This commit adds new "op_http_upgrade_early", that allows to hijack
existing "Deno.HttpConn" acquired from "Deno.serveHttp" API
and performing a Websocket upgrade on this connection.
This is not a public API and is meant to be used internally in the
"ext/node" polyfills for "http" module.

This commit adds a new core API `opAsync2` to call an async op with
atmost 2 arguments. Spread argument iterators has a pretty big perf hit
when calling ops.

Use u16 to represent the kind of event (0 - 6) & event code > 6 is
treated as the close code. This way we can represent all events + the
close code in a single JS number. This is safe because (as per RFC 6455)
close code from 0-999 are reserved & not used.

This commit updates the `Deno.Kv` API to return the new commited
versionstamp for the mutated data from `db.set` and `ao.commit`. This is
returned in the form of a `Deno.KvCommitResult` object that has a
`versionstamp` property.
This reverts commit a3529d0232.
This change made debugging Node tests very hard - `AssertionError` is
now printed as `[Circular *1]` giving no visibility what failed.
We need to align two implementations together and remove this one then.
1. Fixes a cosmetic issue in the repl where it would display lsp warning
messages.
2. Lazily loads dependencies from the package.json on use.
3. Supports using bare specifiers from package.json in the REPL.
Closes #17929
Closes #18494
We currently run the all test cases in `parallel` category at the same
time, which invokes hundreds process at the same time, and that seems
causing some flakiness in CI. (maybe related to #18487)
This PR limits the concurrency to the number of cpu cores. This is more
aligned to how Node.js run their `parallel` test in their repository.

This commit adds associated type to "NodeEnv" trait, called "Fs".
The "Fs" type has a trait bound on "NodeFs", which specifies APIs
required for all ops and resolution APIs to function.
A "RealFs" implementation of "NodeFs" is exported from the "deno_node"
crate, that provides a default implementation for the trait.
All code in "deno_node" extension was changed to use the "NodeFs" trait
to handle file system operations, instead of relying on APIs from the
standard library.
