- fix bugs
2. Ensure there is a related issue and it is referenced in the PR text.
3. Ensure there are tests that cover the changes.
4. Ensure `cargo test` passes.
5. Ensure `./tools/format.js` passes without changing files.
6. Ensure `./tools/lint.js` passes.
7. Open as a draft PR if your work is still in progress. The CI won't
run
all steps, but you can add '[ci]' to a commit message to force it to.
8. If you would like to run the benchmarks on the CI, add the 'ci-bench'

Fixes https://github.com/denoland/deno/issues/26115.
We weren't normalizing the headers to lower case, so code that attempted
to delete the `Content-Length` header (but used a different case) wasn't
actually removing the header.
partially unblocks #25470
This PR aligns the resolution of `localhost` hostname to Node.js
behavior.
In Node.js `dns.lookup("localhost", (_, addr) => console.log(addr))`
prints ipv6 address `::1`, but it prints ipv4 address `127.0.0.1` in
Deno. That difference causes some errors in the work of enabling
`createConnection` option in `http.request` (#25470). This PR fixes the
issue by aligning `dns.lookup` behavior to Node.js.
This PR also changes the following behaviors (resolving TODOs):
- `http.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
- `net.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
These changes are also alignments to Node.js behaviors.
`napi_call_function` should use our equiv of NAPI_PREAMBLE (`&mut Env`
instead of `*mut Env`) since it needs to set error codes based on
whether the body of the function raised a JS exception.

This came up on Discord as a question so I thought it's worth adding a
hint for this as it might be a common pitfall.

Originally I wanted to put them in package.json if there's no deno.json,
but on second thought it makes more sense to just create a deno.json

The significant delay was caused by Nagel's algorithm + delayed ACKs in
Linux kernels. Here's the [kernel
patch](https://lwn.net/Articles/502585/) which added 40ms

When using the `--unstable-detect-cjs` flag or adding `"unstable":
["detect-cjs"]` to a deno.json, it will make a JS file CJS if the
closest package.json contains `"type": "commonjs"` and the file is not
an ESM module (no TLA, no `import.meta`, no `import`/`export`).
