This commit adds support for "rejectionhandled" Web Event and
"rejectionHandled" Node event.
```js
import process from "node:process";
process.on("rejectionHandled", (promise) => {
console.log("rejectionHandled", reason, promise);
});
window.addEventListener("rejectionhandled", (event) => {
console.log("rejectionhandled", event.reason, event.promise);
});
```

Fixes #20516
Follow up to #21747 and #21746
This tackles the last point of #20516 where certain inputs weren't
accepted in the other zlib methods
This adds the `toU8` conversion of `_brotli` to `_zlib.mjs`, when we
create the ZLibBuffer, we'll sanitize the input. I noticed that the
async had no handler for `string` input so I added that as well.
Fixes https://github.com/denoland/deno/issues/21734
Changes:
- Use default encode when options do not provide a encode callback.
- Remove internal TS for `node:querystring`. Its not helping catching
bugs like this because of invalid type assumptions and use of `any`,
more of a maintenance burden.
This fixes point 3 of https://github.com/denoland/deno/issues/20516
This PR creates consistency between the sync and async versions of the
brotli compress where we will always return a buffer like Node.
This fixes point 2 of #20516
This adds a conversion from Dataview/Buffer by returning `obj.buffer`
which can be converted to a `UInt8Array`.
Question: Regarding point 4 of the mentioned issue would it be
appropriate to copy the toU8 helper to the `zlib.mjs` methods?
`opAsync` requires a lookup by name on each async call. This is a
mechanical translation of all opAsync calls to ensureFastOps.
The `opAsync` API on Deno.core will be removed at a later time.
This PR implements the child_process IPC pipe between parent and child.
The implementation uses Windows named pipes created by parent and passes
the inheritable file handle to the child.
I've also replace parts of the initial implementation which passed the
raw parent fd to JS with resource ids instead. This way no file handle
is exposed to the JS land (both parent and child).
`IpcJsonStreamResource` can stream upto 800MB/s of JSON data on Win 11
AMD Ryzen 7 16GB (without `memchr` vectorization)
This PR implements the Node child_process IPC functionality in Deno on
Unix systems.
For `fd > 2` a duplex unix pipe is set up between the parent and child
processes. Currently implements data passing via the channel in the JSON
serialization format.
This commit adds a no-op flushHeaders method to the ServerResponse
object. It is a nop because the ServerResponse implementation is based
on top of the Deno server API instead of the Node `OutgoingMessage`
base.
Fixes #21509
This PR is an attempt to fix
https://github.com/denoland/deno/issues/20293, in which node modules
connecting to databases fail due to TLS errors. I ran into this
attempting to use
[node-postgres](https://github.com/brianc/node-postgres) to connect to a
[Neon](https://neon.tech) database.
Investigating via `--inspect-brk` led me to notice that the hostname
eventually passed to `Deno.startTls` was null. The hostname is
determined by the following code:
f6b889b432/ext/node/polyfills/_tls_wrap.ts (L87-L89)
This logic doesn't appear to be correct. I couldn't find reference to
`servername` existing on the `secureContext` in either Node's or Deno's
docs. There's a lot of scope here, and it's my first time reading
through this code, so I could be missing something!
Node uses [the following
logic](2e458d9736/lib/_tls_wrap.js (L1679-L1682)
) to determine the hostname for certificate validation:
```
const hostname = options.servername ||
options.host ||
(options.socket && options.socket._host) ||
'localhost';
```
This PR updates the `TLSSocket` polyfill to use behave similarly (though
I omitted the default to `localhost` at the end; I'm not sure if
including it is necessary or correct). With this change, `node-postgres`
connects to my TLS endpoint successfully (aside: Neon requires SNI,
which also works as expected).
---
I tried to update the tests in
https://github.com/denoland/deno/blob/main/cli/tests/unit_node/tls_test.ts
to exercise this change, but the test fails for me on `main` on Linux. I
investigated briefly and noticed that the test fixture
`cli/tests/testdata/tls/localhost.crt` doesn't appear to include the
`subjectAltName` specified in `domains.txt`. I believe the certificate
isn't matching `localhost`, but that's where I ended investigating.
This commit refactors how we access "core", "internals" and
"primordials" objects coming from `deno_core`, in our internal JavaScript code.
Instead of capturing them from "globalThis.__bootstrap" namespace, we
import them from recently added "ext:core/mod.js" file.
Add support for signing with a RSA PEM private key: `pkcs8` and `pkcs1`.
Fixes https://github.com/denoland/deno/issues/18972
Ref #21124
Verified fix with `npm:sshpk`. Unverfied but fixes
`npm:google-auth-library`, `npm:web-push` & `oracle/oci-typescript-sdk`

Switch `ext/fetch` over to `resourceForReadableStream` to simplify and
unify implementation with `ext/serve`. This allows us to work in Rust
with resources only.
Two additional changes made to `resourceForReadableStream` were
required:
- Add an optional length to `resourceForReadableStream` which translates
to `size_hint`
- Fix a bug where writing to a closed stream that was full would panic
We can move all promise ID knowledge to deno_core, allowing us to better
experiment with promise implementation in deno_core.
`{un,}refOpPromise(promise)` is equivalent to
`{un,}refOp(promise[promiseIdSymbol])`
Workaround the circular references issue by using a initializer function
to give tty stream class to `initStdin`.

This commit improves "node:http2" module implementation, by enabling
to use "options.createConnection" callback when starting an HTTP2
session.
This change enables to pass basic client-side test with "grpc-js/grpc"
package.
Smaller fixes like "Http2Session.unref()" and "Http2Session.setTimeout()"
were handled as well.
Fixes #16647
For the following example, if I set the encoding to `base64url`, it'll
throw an unexpected TypeError:
```ts
import { Buffer } from "node:buffer";
Buffer.from("IntcImhlbGxvXCI6XCJoZGQvZStpXCJ9Ig", "base64url").toString();
// error: Uncaught TypeError: src.subarray is not a function
// const buf = Buffer.from(
// ^
// at blitBuffer (ext:deno_node/internal/buffer.mjs:1779:15)
// at Uint8Array.base64urlWrite (ext:deno_node/internal/buffer.mjs:691:10)
// at Object.write (ext:deno_node/internal/buffer.mjs:2195:11)
// at Uint8Array.write (ext:deno_node/internal/buffer.mjs:794:14)
// at fromString (ext:deno_node/internal/buffer.mjs:214:22)
// at _from (ext:deno_node/internal/buffer.mjs:119:12)
// at Function.from (ext:deno_node/internal/buffer.mjs:157:10)
// at file:///Users/foodieats/temp/buffer1.ts:3:20
```
The error caused by `base64urlWrite` function, it should call
`forgivingBase64UrlDecode` not `forgivingBase64UrlEncode`
Also fixed #20563 .
This commit improves compatibility of "node:http2" module by polyfilling
"connect" method and "ClientHttp2Session" class. Basic operations like
streaming, header and trailer handling are working correctly.
Refing/unrefing is still a TODO and "npm:grpc-js/grpc" is not yet working
correctly.

When trying to run
```
deno run -A --unstable npm:astro dev
```
in my Astro project it fails with:
```
Node.js v18.12.1 is not supported by Astro!
Please upgrade Node.js to a supported version: ">=18.14.1"
```
My current version is:
```
~ ❯ node --version
v20.5.1
```
Bumping the version to the latest stable Release of node in
`ext/node/polyfills/_process/process.ts` fixes this.
I don't know if this causes any conflicts, so please feel free to
correct me here.
The fix for #20188 was not entirely correct -- we were unlocking the
global buffer incorrectly. This PR introduces a lock state that ensures
we only unlock a lock we have taken out.
The goal of this PR is to address issue #20106 where a `TypeError`
occurs when the variables `uid` and `gid` from `userInfo()` in `node:os`
are reassigned if the user is on Windows. Both `uid` and `gid` are
marked as `const` therefore producing a `TypeError` when the two are
reassigned.
This PR achieves that goal by marking `uid` and `gid` as `let`
To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:
- [x] Process stdin/stdout/stderr are lazily created
- [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added
