I noticed
[`set_response_body`](ce42f82b5a/ext/http/service.rs (L439-L443))
was unexpectedly hot in profiles, with most of the time being spent in
`memmove`.
It turns out that `ResponseBytesInner` was _massive_ (5624 bytes), so
every time we moved a `ResponseBytesInner` (for instance in
`set_response_body`) we were doing a >5kb memmove, which adds up pretty
quickly.
This PR boxes the two larger variants (the compression streams),
shrinking `ResponseBytesInner` to a reasonable 48 bytes.

This PR resolves a handful of issues with child_process IPC. In
particular:
- We didn't support sending typed array views over IPC
- Opening an IPC channel resulted in the event loop never exiting
- Sending a `null` over IPC would terminate the channel
- There was some UB in the read implementation (transmuting an `&[u8]`
to `&mut [u8]`)
- The `send` method wasn't returning anything, so there was no way to
signal backpressure (this also resulted in the benchmark
`child_process_ipc.mjs` being misleading, as it tried to respect
backpressure. That gave node much worse results at larger message sizes,
and gave us much worse results at smaller message sizes).
- We weren't setting up the `channel` property on the `process` global
(or on the `ChildProcess` object), and also didn't have a way to
ref/unref the channel
- Calling `kill` multiple times (or disconnecting the channel, then
calling kill) would throw an error
- Node couldn't spawn a deno subprocess and communicate with it over IPC
This commit duplicates ops from "ext/fetch" to "ext/node" to
kick off a bigger rewrite of "node:http".
Most of duplication is temporary and will be removed as these
ops evolve.
Support `MessagePort.once` in Node mode and enable relevant
`worker_threads` test. Noticed that another Node test was passing as
well, so I enabled that too.
This change aims to replace all relative import specifiers targeted at
`tests/util/std` with mapped ones (using a `deno.json` file). Towards
updating the `std` git submodule.
Sending ALPN to a proxy, and then when tunneling, requires better
juggling of TLS configs. This improves the choice of TLS config in the
proxy connector, based on what reqwest does. It also includes some
`ext/fetch/tests.rs` that check the different combinations.
Fixes #24632
Fixes #24691
The intent is that those tests will be executed, but our check that the
files are up to date won't overwrite the contents of the tests. This is
useful when a test needs some manual edits to work.
It turns out we weren't actually running them.
---
This ended up turning into a couple of small bug fixes to get the tests
passing:
- We weren't canonicalizing the exec path properly (it sometimes still
had `..` or `.` in it)
- We weren't accepting strings in `process.exit`
There was one failure I couldn't figure out quickly, so I disabled the
test for now, and filed a follow up issue: #24694
This is in preparation for extracting out node resolution code from
ext/node (which is something I'm going to do gradually over time).

This makes it easier to tell what kind of error something is (even for
deeply nested errors) and will help in the future once we add error
codes to the JS errors this returns.
This commit re-implements `ext/fetch` and all dependent crates
using `hyper` and `hyper-util`, instead of `reqwest`.
The reasoning is that we want to have greater control and access
to low level `hyper` APIs when implementing `fetch` API as well
as `node:http` module.

Ensure that the prefix is properly adjusted when dealing with IPv4

Reason is that `e` may contain an invalid package target nested deeply
in the returned errors. We should probably add a `.code()` to all errors
to make matching easier or make the errors flatter.
This PR stubs `perf_hooks.eventLoopUtilization` to make the tests of

Adds support for running npm package lifecycle scripts, opted into via a
new `--allow-scripts` flag.
With this PR, when running `deno cache` (or `DENO_FUTURE=1 deno
install`) you can specify the `--allow-scripts=pkg1,pkg2` flag to run
lifecycle scripts attached to the given packages.
Note at the moment this only works when `nodeModulesDir` is true (using
the local resolver).
When a package with un-run lifecycle scripts is encountered, we emit a
warning suggesting things may not work and to try running lifecycle
scripts. Additionally, if a package script implicitly requires
`node-gyp` and it's not found on the system, we emit a warning.
Extra things in this PR:
- Extracted out bits of `task.rs` into a separate module for reuse
- Added a couple fields to `process.config` in order to support
`node-gyp` (it relies on a few variables being there)
- Drive by fix to downloading new npm packages to test registry
---
TODO:
- [x] validation for allow-scripts args (make sure it looks like an npm
package)
- [x] make allow-scripts matching smarter
- [ ] figure out what issues this closes
---
Review notes:
- This adds a bunch of deps to our test registry due to using
`node-gyp`, so it's pretty noisy
The implementation for `assert.throws()` from `node:assert` didn't work
when the expected value was an `Error` constructor. In this case the
thrown error should checked if it's an instance of said constructor.
Fixes https://github.com/denoland/deno/issues/24464
Previously we had many different code paths all
handling digests in different places, all with
wildly different digest support. This commit
rewrites this to use a single digest handling
mechanism for all digest operations.
It adds various aliases for digest algorithms,
like node does. For example
`sha1WithRSAEncryption` is an alias for `sha1`.
It also adds support for `md5-sha1` digests in
various places.
It's perfectly valid to access `server.address()` before calling
`.listen()`. Until a server actively listens on a socket Node will
return `null` here, but we threw a "Cannot access property 'port' of
undefined" instead.
This was discovered when inspecting failures in Koa's test suite with
Deno.
Part of #18218
- Adds `fs.lutimes` and `fs.lutimesSync` to our node polyfills. To do
this I added methods to the `FileSystem` trait + ops to expose the
functionality to JS.
- Exports `fs._toUnixTimestamp`. Node exposes an internal util
`toUnixTimestamp` from the fs module to be used by unit tests (so we
need it for the unit test to pass unmodified). It's weird because it's
only supposed to be used internally but it's still publicly accessible
- Matches up error handling and timestamp handling for fs.futimes and
fs.utimes with node
- Enables the node_compat utimes test - this exercises futimes, lutimes,
and utimes.
Changes in this PR:
- Added new fixed size hash algorithms (blake2b512, blake2s256,
sha512-224, sha512-256, sha3-224, sha3-256, sha3-384, sha3-512, sm3)
- Added variable size hash algorithms (the concept), with the algorithms
shake128 and shake256
- Use cppgc instead of resources for the hasher
- Enable Node's crypto.Hash tests and fix found bugs
- add fallback impls of external string apis which always copy. after
upstream changes to rusty_v8 we can support non-copying api as well.
- `napi_get_buffer_data` needs to work on all TypedArray instances.
- Fixes: https://github.com/denoland/deno/issues/24209
- `target_defaults.default_configuration` is used by some modules to
find the corresponding node file from node-gyp
- `node_api_get_module_filename` expects the filename to be a `file:`
url.

Previously res.setHeader("foo", ["bar", "baz"]) added a single header
with a value of `bar,baz`. Really this should add two separate headers.
This is visible in `set-cookie` for example.
Previously the asynchronous read of the blob would not block sends that
are started later. We now do this, but in such a way as to not regress
performance in the common case of not using `Blob`.
Previously various reads of files in `node_modules` would error on
invalid UTF-8. These were cases involving:
- reading package.json from Rust
- reading package.json from JS
- reading CommonJS files from JS
- reading CommonJS files from Rust (for ESM translation)
- reading ESM files from Rust
Also removes permissions being passed in for node resolution. It was
completely useless because we only checked it for reading package.json
files, but Deno reading package.json files for resolution is perfectly
fine.
My guess is this is also a perf improvement because Deno is doing less
work.

This allows for asynchronous cleanup before process termination
without immediately exiting.
- **Ensures type safety**: The setter for `Deno.exitCode` validates that

This patch fixes stdin read hanging on user input when switching tty
mode on Windows
Fixes #21111
On Windows, when switching from line to raw mode:
- Cancel ongoing console read by writing a return keypress to its input
buffer. This blocks the main thread until any ongoing read has been
cancelled to prevent interference with the screen state.
- On the read thread, restore the cursor position to where it was before
writing the enter, undoing its effect on the screen state.
- Restart reading and notify the main thread.
This commit changes `gzip` compression in `Deno.serve` API to flush data
after each write. There's a slight performance regression, but provided
test shows a scenario that was not possible before.

We didn't honour the `position` options of `fd.read` and `fd.write`
because we checked if the buffer is of type `Buffer` instead of just
`Uint8Array`. Node does the latter. In doing so I noticed that the file
handle id was written to a public property which it definitely shouldn't
be. This was probably a typo.

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.

Because the buffers are `MaybeUninit<V8Slice<u8>`, and the owner of the
`BoundedBufferChannel` is not obligated to read each and every bit of
data, we may find that some buffers were not automatically dropped if
unread by the time the `BoundedBufferChannelInner` is dropped.
Possible repro:
```
Deno.serve(() => new Response(new ReadableStream({ start(controller) { controller.enqueue(new Uint8Array(100_000_000)) } })));

```bash
while true; do curl localhost:8000 | dd count=1; done

1. Generally we should prefer to use the `log` crate.
2. I very often accidentally commit `eprintln`s.
When we should use `println` or `eprintln`, it's not too bad to be a bit
more verbose and ignore the lint rule.

Part of #22607 (probably closes it, but I haven't done thorough testing)
Makes it so that `require.resolve` with `paths` specified will fallback
to using the global cache when the paths can't be found when using a
global cache (not when using a node_modules folder)
