This commit deprecates "--unstable" flag.
When "--unstable" flag is encountered a warning like this is printed:
```
The `--unstable` flag is deprecated, use granular `--unstable-*` flags instead.
Learn more at: https://docs.deno.com/runtime/manual/tools/unstable_flags
```
When "--unstable" flag is used and an unstable API is called an
additional warning like this is printed for each API call:
```
The `Deno.dlopen` API was used with `--unstable` flag. The `--unstable` flag is deprecated, use granular `--unstable-ffi` instead.
Learn more at: https://docs.deno.com/runtime/manual/tools/unstable_flags
```
When no "--unstable-*" flag is provided and an unstable API is called
following
warning is issued before exiting:
```
Unstable API 'Deno.dlopen'. The `--unstable-ffi` flag must be provided.

This change removes the currently deprecated `Deno.cron()` overload with
`options` as a potential last argument.
This might be fine to do now, in a major release, as `Deno.cron()` is an
unstable API. I thought of doing this while working on #22021. If this
is not ready to remove, I can instead set the removal version of this
overload for Deno v2.
Note: this overload was deprecated in Deno v1.38.2 (#21225). So it's
been deprecated for over 2 months.
Closes https://github.com/denoland/deno/issues/21828.
This API is a huge footgun. And given that "Deno.serveHttp" is a
deprecated API that is discouraged to use (use "Deno.serve()"
instead); it makes no sense to keep this API around.
This is a step towards fully migrating to Hyper 1.

Part 1 of a potential 3 part series. Ref #13449
The current implementation passes key material back and forth RustCrypto
group of crates and ring. ring does not implement p521 yet.
This PR adds support for P521 named curve in `generateKey` and
`importKey` where we use RustCrypto. Other parts should be moved over to
the RustGroup group of crates for consistency.
Part 1 of #21713
Changes:
- Remove `.present()` and add a `presentGPUCanvasContext` (not exposed
yet to users)
- Move lazy load logic to `00_init.js`. This can be used to use webgpu
on-demand from future code (OffScreenCanvas)
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?
Main change is that:
- "hyper" has been renamed to "hyper_v014" to signal that it's legacy
- "hyper1" has been renamed to "hyper" and should be the default
`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.
When we migrate to op-import-per-extension, we will want to ensure that
ops have one and only one place where they are imported. This tackles
the ops that are imported via `ensureFastOps`, but does not yet tackle
direct `ops` imports.

Node HTTP/2 was using the default h2 `Bytes` datatype when we can be

are using `reqwest` which is stuck on hyper 0.x at this time.
This PR implements the child_process IPC pipe between parent and child.
The implementation uses Windows named pipes created by parent and passes

is exposed to the JS land (both parent and child).

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.
Part 2 of removing middleware.
This is somewhat awkward because `V8CrossThreadTaskSpawner` requires
tasks to be `Send`, but NAPI makes heavy use of `!Send` pointers. In
addition, Rust causes a closure to be `!Send` if you pull a `!Send`
value out of a struct.

This significantly optimizes URLPattern in the case where the same
URL is matched against many patterns (like in a router).
Also minor speedups to other use-cases.
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

We needed to update 99_main.js and a whole load of tests.
API changes:
- setPromiseRejectCallback becomes setUnhandledPromiseRejectionHandler.
The function is now called from eventLoopTick.
- The promiseRejectMacrotaskCallback no longer exists, as this is
automatically handled in eventLoopTick.
- ops.op_dispatch_exception now takes a second parameter: in_promise.
The preferred way to call this op is now reportUnhandledException or
reportUnhandledPromiseRejection.

Switch `ext/fetch` over to `resourceForReadableStream` to simplify and

- 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
Rust 1.74 may have made this code temporarily valid in [#113126 Replace

The `httpServerExplicitResourceManagement` tests were randomly failing
on CI because of a race.
The `drain` waker was missing wakeup events if the listeners shut down
after the last HTTP response finished. If we lost the race (rare), the
server Rc would be dropped and we wouldn't poll it again.
This replaces the drain waker system with a signalling Rc that always
resolves when the refcount is about to become 1.
Fix verified by running serve tests in a loop:
```
for i in {0..100}; do cargo run --features=__http_tracing -- test
-A --unstable '/Users/matt/Documents/github/deno/deno/cli/tests/unit/ser
ve_test.ts' --filter httpServerExplicitResourceManagement; done;

)
Deno.cron(
name: string,
schedule: string,
options?: { backoffSchedule?: number[]; signal?: AbortSignal },
handler: () => Promise<void> | void,

of the crons was closed using `signal`.

This commit adds granular `--unstable-*` flags:
- "--unstable-broadcast-channel"
- "--unstable-ffi"
- "--unstable-fs"
- "--unstable-http"
- "--unstable-kv"
- "--unstable-net"
- "--unstable-worker-options"
- "--unstable-cron"
These flags are meant to replace a "catch-all" flag - "--unstable", that
gives a binary control whether unstable features are enabled or not. The
downside of this flag that allowing eg. Deno KV API also enables the FFI
API (though the latter is still gated with a permission).
These flags can also be specified in `deno.json` file under `unstable`
key.
Currently, "--unstable" flag works the same way - I will open a follow
up PR that will print a warning when using "--unstable" and suggest to use
concrete "--unstable-*" flag instead. We plan to phase out "--unstable"
completely in Deno 2.
Implements `WebSocket` over http/2. This requires a conformant http/2
server supporting the extended connect protocol.
Passes approximately 100 new WPT tests (mostly `?wpt_flags=h2` versions
of existing websockets APIs).
This is implemented as a fallback when http/1.1 fails, so a server that
supports both h1 and h2 WebSockets will still end up on the http/1.1
upgrade path.
The patch also cleas up the websockets handshake to split it up into
http, https+http1 and https+http2, making it a little less intertwined.
This uncovered a likely bug in the WPT test server:

This PR adds unstable `Deno.cron` API to trigger execution of cron jobs.
* State: All cron state is in memory. Cron jobs are scheduled according
to the cron schedule expression and the current time. No state is
persisted to disk.
* Time zone: Cron expressions specify time in UTC.
* Overlapping executions: not permitted. If the next scheduled execution
time occurs while the same cron job is still executing, the scheduled
execution is skipped.
* Retries: failed jobs are automatically retried until they succeed or
until retry threshold is reached. Retry policy can be optionally
specified using `options.backoffSchedule`.
Use new https://github.com/denoland/rustls-tokio-stream project instead
of tokio-rustls for direct websocket connections. This library was
written from the ground up to be more reliable and should help with
various bugs that may occur due to underlying bugs in the old library.

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
Otherwise you can not return `Deno.Server` from async functions.

Migrate to op2. Making a few decisions to get this across the line:
- Empty slices, no matter where the come from, are null pointers. The v8
bugs (https://bugs.chromium.org/p/v8/issues/detail?id=13489) and
(https://bugs.chromium.org/p/v8/issues/detail?id=13488) make passing
around zero-length slice pointers too dangerous as they might be
uninitialized or null data.
- Offsets and lengths are `#[number] isize` and `#[number] usize`
respectively -- 53 bits should be enough for anyone
- Pointers are bigints. This is a u64 in the fastcall world, and can
accept Integer/Int32/Number/BigInt v8 types in the slow world.
fixes #20454
Current KV queues implementation assumes that `enqueue` and
`listenQueue` are called on the same instance of `Deno.Kv`. It's
possible that the same Deno process opens multiple KV instances pointing
to the same fs path, and in that case `listenQueue` should still get
notified of messages enqueued through a different KV instance.
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 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 .
We can go one level down in abstraction and avoid using the public
`ReadableStream` APIs.

This commit improves async op sanitizer speed by only delaying metrics
collection if there are pending ops. This
results in a speedup of around 30% for small CPU bound unit tests.
It performs this check and possible delay on every collection now,
fixing an issue with parent test leaks into steps.
This commit adds "deno jupyter" subcommand which
provides a Deno kernel for Jupyter notebooks.
The implementation is mostly based on Deno's REPL and
reuses large parts of it (though there's some clean up that
needs to happen in follow up PRs). Not all functionality of
Jupyter kernel is implemented and some message type
are still not implemented (eg. "inspect_request") but
the kernel is fully working and provides all the capatibilities
that the Deno REPL has; including TypeScript transpilation
and npm packages support.
Closes https://github.com/denoland/deno/issues/13016

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.

This PR implements a graceful shutdown API for Deno.serve, allowing all
current connections to drain from the server before shutting down, while
preventing new connections from being started or new transactions on
existing connections from being created.
We split the cancellation handle into two parts: a listener handle, and
a connection handle. A graceful shutdown cancels the listener only,
while allowing the connections to drain. The connection handle aborts
all futures. If the listener handle is cancelled, we put the connections
into graceful shutdown mode, which disables keep-alive on http/1.1 and
uses http/2 mechanisms for http/2 connections.
In addition, we now guarantee that all connections are complete or
cancelled, and all resources are cleaned up when the server `finished`
promise resolves -- we use a Rust-side server refcount for this.
Performance impact: does not appear to affect basic serving performance
by more than 1% (~126k -> ~125k)

Fixes https://github.com/denoland/deno/issues/19816
In that issue, I suggest switching over the other brotli functionality
to the Rust API provided by the `brotli` crate. Here, I only do that
with the `brotli_decompress` function to fix the bug with buffers longer
than 4096 bytes.
Keys are expensive metadata. We track it for various purposes, e.g.
transaction conflict check, and key expiration.
This patch limits the total key size in an atomic operation to 80 KiB
(81920 bytes). This helps ensure efficiency in implementations.
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.
Rewrites 3 ops that used "op(deferred)" to use "op2(async(lazy))"
instead.
This will allow us to remove codepath for handling "deferred" ops in
"deno_core".
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.
When a TCP connection is force-closed (ie: browser refresh), the
underlying future we pass to Hyper is dropped which may cause us to try
to drop the body resource while the OpState lock is still held.
Preconditions for this bug to trigger:
- The body resource must have been taken
- The response must return a resource (which requires us to take the
OpState lock)
- The TCP connection must have been dropped before this
Fixes #20315 and #20298

This patch adds a `remote` backend for `ext/kv`. This supports
connection to Deno Deploy and potentially other services compatible with
the KV Connect protocol.
Deno.serve's fast streaming implementation was not keeping the request
body resource ID alive. We were taking the `Rc<Resource>` from the
resource table during the response, so a hairpin duplex response that
fed back the request body would work.
However, if any JS code attempted to read from the request body (which
requires the resource ID to be valid), the response would fail with a
difficult-to-diagnose "EOF" error.
This was affecting more complex duplex uses of `Deno.fetch` (though as
far as I can tell was unreported).
Simple test:
```ts
const reader = request.body.getReader();
return new Response(
new ReadableStream({
async pull(controller) {
const { done, value } = await reader.read();
if (done) {
controller.close();
} else {
controller.enqueue(value);
}
},
}),
```
And then attempt to use the stream in duplex mode:
```ts
async function testDuplex(
reader: ReadableStreamDefaultReader<Uint8Array>,
writable: WritableStreamDefaultWriter<Uint8Array>,
) {
await writable.write(new Uint8Array([1]));
const chunk1 = await reader.read();
assert(!chunk1.done);
assertEquals(chunk1.value, new Uint8Array([1]));
await writable.write(new Uint8Array([2]));
const chunk2 = await reader.read();
assert(!chunk2.done);
assertEquals(chunk2.value, new Uint8Array([2]));
await writable.close();
const chunk3 = await reader.read();
assert(chunk3.done);
}
```
In older versions of Deno, this would just lock up. I believe after
23ff0e722e, it started throwing a more
explicit error:
```
httpServerStreamDuplexJavascript => ./cli/tests/unit/serve_test.ts:1339:6
error: TypeError: request or response body error: error reading a body from connection: Connection reset by peer (os error 54)
at async Object.pull (ext:deno_web/06_streams.js:810:27)
```
Properly handle the `SQLITE_BUSY` error code by retrying the
transaction.
Also wraps database initialization logic in a transaction to protect
against incomplete/concurrent initializations.
Fixes https://github.com/denoland/deno/issues/20116.
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
