A workaround for the issue #25480
`Deno.Listener` can't be closed synchronously after `accept()` is
called. This PR delays the `accept` call 2 ticks (The listener callback
is called 1 tick later. So the 1 tick delay is not enough), and makes
`net.Server` capable of being closed synchronously.
This unblocks `npm:detect-port` and `npm:portfinder`
closes #18301
closes #25175
Closes https://github.com/denoland/deno/issues/25321
Ended up being a larger refactoring, since we're now juggling
(potentially) two config files in the same `add`, instead of choosing
one. I don't love the shape of the code, but I think it's good enough
Some smaller side improvements:
- `deno remove` supports `jsonc`
- `deno install --dev` will be a really simple change
- if `deno remove` removes the last import/dependency in the
`imports`/`dependencies`/`devDependencies` field, it removes the field
instead of leaving an empty object
This commit adds:
- `addAbortListener` in `node:events`
- `aborted` in `node:util`
- `execPath` and `execvArgs` named export from `node:process`
- `getDefaultHighWaterMark` from `node:stream`
The `execPath` is very hacky - because module namespaces can not have
real getters, `execPath` is an object with a `toString()` method that on
call returns the actual `execPath`, and replaces the `execPath` binding
with the string. This is done so that we don't require the `execPath`
permission on startup.
This commit changes when to cause the hostname substition of `0.0.0.0` ->
`localhost`.
Currently we substitute `localhost` to the hostname on windows before
calling `options.onListen`, which prevents the users to do more advanced
thing using hostname string like
https://github.com/denoland/std/issues/5558. This PR changes it not to
substitute it when the user provide `onListen` callback.
closes #24776

This change fixes the handling of upgraded socket from `node:http` module.
In `op_node_http_fetch_response_upgrade`, we create DuplexStream paired
with `hyper::upgrade::Upgraded`. When the connection is closed from the
server, the read result from `Upgraded` becomes 0. However because we
don't close the paired DuplexStream at that point, the Socket object in
JS side keeps alive even after the server closed. That caused the issue
#20179
This change fixes it by closing the paired DuplexStream when the
`Upgraded` stream returns 0 read result.
closes #20179
This allows using npm deps of jsr deps without having to add them to the
root package.json.
Works by taking the package requirement and scanning the
`node_modules/.deno` directory for the best matching package, so it
relies on deno's node_modules structure.
Additionally to make the transition from package.json to deno.json
easier, Deno now:
1. Installs npm deps in a deno.json at the same time as installing npm
deps from a package.json.
2. Uses the alias in the import map for `node_modules/<alias>` for
better package.json compatiblity.
Remove `--allow-hrtime` and `--deny-hrtime`. We are doing this because
it is already possible to get access to high resolution timers through
workers and SharedArrayBuffer.

Turns out we only virtualized it so one could have a `Console` property,

If a node addon is using the legacy `napi_module_register` on ctor
approach to module registration, we have to store the registered module
so that other threads can load the addon (because `napi_module_register`
will only be called once per process).
Fixes #23281. Part of #20613.
We were emitting the `online` event in the constructor, so the caller
could never receive it (since there was no time for them to add a
listener). Instead, emit the event where it's intended – after the
worker is initialized.

After this parcel no longer freezes, but still will fail due to other
bugs (which will be fixed in other PRs)
This commit makes various limit parameters in `deno_kv` configurable.
Currently these values are declared as constants and thus can't be
modified from outside. However, there may be situations where we want to
change it. This commit makes this possible by introducing a new struct
`KvConfig` that needs to be given as the 2nd param in `init_ops`.
- Add missing exports to `node:cluster`
- Fix default export not being an instance of `EventEmitter`
- Fix aliasing of properties
- Fix `disconnected` -> `disconnect` export naming
This makes `log4js` work in Deno. `karma` starts too, but somehow the
server isn't responding. That looks like a different issue.
Fixes https://github.com/denoland/deno/issues/24858
This commit gets deno_node's customizer to use fixed-length array
instead of `Vec` to avoid wrong capacity allocation.
In the previous code we reserve a capacity of 14 for
`external_references`. However, after pushing all the necessary
`ExternalReference`s, it ends up with a length of 21, not 14. This means
another allocation happens even though we reserve some space.
To make sure that there will no longer be extra allocation, it should be
a good idea to use fixed-length array here.
This commit bumps the minimum required version of `dsa` crate to 0.6.3.

This PR addresses a regression introduced in
https://github.com/denoland/deno/pull/25021 that would cause the
`req.url` parameter in Node's http server to always be a single
character instead of the expected value. The regression was caused by
effectively calling `.indexOf()` on an empty string and thus passing the
wrong index for slicing.
```js
"".indexOf("/") // -> -1
request.url.slice(-1) // effectively only giving us the last character
```

PrismJS uses `WorkerGlobalScope` and `self` for detecting browser's Web
Worker context:
59e5a34713/prism.js (L11)
Now the detection logic above is broken when it's imported from Deno's
Web Worker context because we only hide `self` (Prism assumes when
`WorkerGlobalScope` is available, `self` is also available).
This change fixes the above by also hiding `WorkerGlobalScope` global in
Node compat mode.
closes #25008
My fix in #25030 was buggy, I forgot to pass the `byteOffset` and
`byteLength`. Whoops.
I also discovered that fs.read was not respecting the `offset` argument,
and we were constructing a new `Buffer` for the callback instead of just
passing the original one (which is what node does, and the @types/node
definitions also indicate the callback should get the same type).
Fixes #25028.

After this PR, playwright is functional on mac/linux.
Adds a `parallel` flag to `deno serve`. When present, we spawn multiple
workers to parallelize serving requests.
```bash
deno serve --parallel main.ts
```
Currently on linux we use `SO_REUSEPORT` and rely on the fact that the
kernel will distribute connections in a round-robin manner.
On mac and windows, we sort of emulate this by cloning the underlying
file descriptor and passing a handle to each worker. The connections
will not be guaranteed to be fairly distributed (and in practice almost
certainly won't be), but the distribution is still spread enough to
provide a significant performance increase.

Part of #25028.
Our underlying read/write operations in `io` assume the buffer is a
Uint8Array, but we were passing in other typed arrays (in the case above
it was `Int8Array`).
There is no constructor code when creating an inspector `Session`
instance in Node. Also get rid of some symbols which should've been
private properties. This PR doesn't yet add any new implementations
though as these are mostly cosmetic changes.
For some reason we didn't register the `node:inspector` module, which
lead to a panic when trying to import it. This PR registers it.

- **Key pair generation**
- Overhauled, but supported APIs unchanged
This PR adds a lot of new individual functionality. But most importantly
because
of the new key material representation, it is now trivial to add new
algorithms
(as shown by this PR).
Now, when adding a new algorithm, it is also widely supported - for
example
previously we supported ED25519 key pair generation, but we could not
import,
export, sign or verify with ED25519. We can now do all of those things.
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

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 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.

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

- [x] validation for allow-scripts args (make sure it looks like an npm
package)
- [x] make allow-scripts matching smarter

Review notes:
- This adds a bunch of deps to our test registry due to using
`node-gyp`, so it's pretty noisy
