We didn't support the `throwIfNoEntry` option for Node's `fs.lstatSync`
method. Note that the async variant doesn't have this option.
Fixes https://github.com/denoland/deno/issues/23996
The mixed `number | bigint` representation was useful optimization for
pointers. Now, pointers are represented as V8 externals. As part of the
FFI stabilization effort we want to make `bigint` the only
representation for `u64` and `i64`.
BigInt representation performance is almost on par with mixed
representation with the added benefit that its less confusing and users
don't need manual checks and conversions for doing operations on the
value.

Closes #19697. This fixes a bug where the writeFile API can create
partially-overwritten files which may lead to invalid / corrupt files or
data leakage. It also aligns the behavior of writing a ReadableStream
and writing a Uint8Array to the disk.
`createAsyncFromSyncIterator(x)` which is used in
`ReadableStream.from()` expects `x` as `Iterable` but, previous
implements specify `Iterator` or `IterableIterator`. If it was
`IterableIterator`, it would work, but if it was `Iterator`, an
exception will occur.
Tests have been merged into WPT.

Enhanced warning message for --env flag with run and eval subcommands.
The commit is specifically made to address issue #23674 by improving the
warning messages that appear when using the --env flag with run or eval
subcommands in the following scenarios:
1. Missing environment file.
2. Incorrect syntax in the environment file content.
**Changes made**
- Distinguishes between cases of missing environment file and wrong
syntax in the environment file content.
- Shows a concise warning message to convey the case/issue occurred.
**Code changes & enhancements**
- Implemented a match statement to handle different types of errors
received while getting and parsing the file content to display a concise
warning message, rather than simple error check and then displaying the
same warning message for whatever the type of error is.
- Updated the related existing tests to reflect the new warning
messages.
- Added two test cases to cover the wrong environment file content
syntax with both run and eval subcommands.
**Impact**
The use of --env flag with both run/eval would be more user-friendly as
it gives a precise description of what is not right when using
incorrectly.
If you could give it a look, @dsherret , I appreciate your feedback on
these changes.

Node sets the default HTTP response status code to 200 on the
`ServerResponse`. We initialised it as `undefined` before which caused a
problem with 11ty's dev server.
Thanks to @vrugtehagel for reporting this issue and finding the correct
fix as well 🎉

This commit adds initial support for ".npmrc" files.
Currently we only discover ".npmrc" files next to "package.json" files
and discovering these files in user home dir is left for a follow up.
This pass supports "_authToken" and "_auth" configuration
for providing authentication.
LSP support has been left for a follow up PR.
Towards https://github.com/denoland/deno/issues/16105
Fixes #23571.
Previously, we required a `deno.json` to be present (or the `--lock`
flag) in order for us to resolve a `deno.lock` file. This meant that if
you were using deno in an npm-first project deno wouldn't use a
lockfile.
Additionally, while I was fixing that, I discovered there were a couple
bugs keeping the future `install` command from using a lockfile.
With this PR, `install` will actually resolve the lockfile (or create
one if not present), and update it if it's not up-to-date. This also
speeds up `deno install`, as we can use the lockfile to skip work during
npm resolution.
This PR removes the use of the custom `utc_now` function in favor of the
`chrono` implementation. It resolves #22864.

If `@@asyncIterator` is `null` or `undefined`, it should ignores and
fallback to `@@iterator`.
Tests have been merged into WPT.
https://github.com/web-platform-tests/wpt/pull/46374
The proposal of `ReadableStream.from` uses TC39 [GetIterator][] and
[GetMethod][] within it.
GetMethod treats null as undefined.
So if `@@asyncIterator` is `null` it should be ignored and fallback to
`@@iterator`.
[GetIterator]: https://tc39.es/ecma262/#sec-getiterator
[GetMethod]: https://tc39.es/ecma262/#sec-getmethod
```bash
> deno eval "ReadableStream.from({ [Symbol.asyncIterator]: null, [Symbol.iterator]: () => ({ next: () => ({ done: true }) }) }).pipeTo(new WritableStream())"

([example](https://github.com/denoland/deno/actions/runs/9192958846/job/25282900321#step:43:2772))
due to the output changing slightly

I'm not sure what changed in CI to cause this (and I can't repro it
locally, even matching the version of npm and node on the github
runners), but fix it with more lenient expected output for that test.
By default, uses a 60 second timeout, backing off 2x each time (can be
overridden using the hidden `DENO_SLOW_TEST_TIMEOUT` which we implement
only really for spec testing.
```
Deno.test(async function test() {
await new Promise(r => setTimeout(r, 130_000));
});
```
```

This brings in [`runtimelib`](https://github.com/runtimed/runtimed) to
use:
## Fully typed structs for Jupyter Messages
```rust
let msg = connection.read().await?;
self
.send_iopub(
runtimelib::Status::busy().as_child_of(msg),
)
.await?;
```
## Jupyter paths
Jupyter paths are implemented in Rust, allowing the Deno kernel to be
installed completely via Deno without a requirement on Python or
Jupyter. Deno users will be able to install and use the kernel with just
VS Code or other editors that support Jupyter.
```rust
pub fn status() -> Result<(), AnyError> {
let user_data_dir = user_data_dir()?;
let kernel_spec_dir_path = user_data_dir.join("kernels").join("deno");
let kernel_spec_path = kernel_spec_dir_path.join("kernel.json");
if kernel_spec_path.exists() {
log::info!("✅ Deno kernel already installed");
Ok(())
} else {
log::warn!("ℹ️ Deno kernel is not yet installed, run `deno jupyter --install` to set it up");
Ok(())
}
}
```
Closes https://github.com/denoland/deno/issues/21619
This stubs `findSourceMap` in `node:module` by always returning
`undefined` as if it never found a source map. This unblocks the `ava`
test runner.

Some npm libraries like `signal-exit` rely on the length of the listener
array returned by `process.listeners("SIGNT")` to be correct to
function. We weren't tracking `SIG*` events there, which broke those npm
libraries.

Popular test runners like Jest instantiate a new `Process` object
themselves and expect the class constructor to be callable without the
`new` keyword. This PR refactors our `Process` class implementation from
a proper ES2015 class to an ES5-style class which can be invoked both
with and without the `new` keyword like in Node.
