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`.
This PR adds a new unstable "bring your own node_modules" (BYONM)
functionality currently behind a `--unstable-byonm` flag (`"unstable":
["byonm"]` in a deno.json).
This enables users to run a separate install command (ex. `npm install`,
`pnpm install`) then run `deno run main.ts` and Deno will respect the
layout of the node_modules directory as setup by the separate install
command. It also works with npm/yarn/pnpm workspaces.
For this PR, the behaviour is opted into by specifying
`--unstable-byonm`/`"unstable": ["byonm"]`, but in the future we may
make this the default behaviour as outlined in
https://github.com/denoland/deno/issues/18967#issuecomment-1761248941
This is an extremely rough initial implementation. Errors are
terrible in this and the LSP requires frequent restarts. Improvements
will be done in follow up PRs.
Right now, if one of the linters fails, the all other ones continue
running in the background. This fixes this by waiting until all linters
are done before settling.
Running `tools/wpt.ts` with a filter would cause an error if there were
extra, leftover expectations in expectations.json. These errors would
not appear if no filter was passed, often leaving the filtered version
of the test runner broken.
This also introduces a smarter bit of logic where filters can be
specified with a leading slash (`tools/wpt.ts run -- /url` is equivalent
to `tools/wpt.ts run -- url`)
Makes the prebuilt installation a bit more reliable:
- Check for 200
- Check for an executable header (MZ, ELF, etc)
- Download to a .temp file until we're certain the file is valid
- If multiple requests for a tool are made, only run one task
This PR ensures that the original signal event is fired before any
dependent signal events.

This could be a [stream spec](https://streams.spec.whatwg.org) bug
When `controller.close` is called on a byob stream, there's no cleanup
of pending `readIntoRequests`. The only cleanup of pending
`readIntoRequests` happen when `.byobRequest.respond(0)` is called, it
happens
here:6ba245fe25/ext/web/06_streams.js (L2026)
which ends up calling `readIntoRequest.closeSteps(chunk);` in
6ba245fe25/ext/web/06_streams.js (L2070)
To reproduce:
```js
async function byobRead() {
const input = [new Uint8Array([8, 241, 48, 123, 151])];
const stream = new ReadableStream({
type: "bytes",
async pull(controller) {
if(input.length === 0) {
controller.close();
// controller.byobRequest.respond(0); // uncomment for fix
return
}
controller.enqueue(input.shift())
},
});
const reader = stream.getReader({ mode: 'byob' });
const r1 = await reader.read(new Uint8Array(64));
console.log(r1);
const r2 = await reader.read(new Uint8Array(64));
console.log(r2);
}
await byobRead();
```
Running the script triggers:
```
error: Top-level await promise never resolved
```
This addresses issue #19918.
## Issue description
Event messages have the wrong isTrusted value when they are not
triggered by user interaction, which differs from the browser. In
particular, all MessageEvents created by Deno have isTrusted set to
false, even though it should be true.
This is my first ever contribution to Deno, so I might be missing
something.
Fixes the WPT tests that test w/invalid codes. Also explicitly ignoring
some h2 tests to hopefully prevent flakes.
The previous changes to WebSocketStream introduced a bug where the close
errors were not made available if the `pull` method was re-entrant.
The copyright checker was allowing files with code above the copyright
line in a few places, mainly as a result of IDEs ordering imports
improperly.
This makes the check more robust, and adds a whitelist of valid lines
that may appear before the copyright line.
This is a quick tool that I've been using to build benchmarking builds
for Deno.
Usage:
Build a benchmark `HEAD~1` and `origin/main` executable:
```sh
deno run tools/build_bench.ts HEAD~1 origin/main
```
Build debug benchmark executables of the last three commits:
```sh
deno run tools/build_bench.ts --profile debug HEAD HEAD~1 HEAD~2
```
Adds an import map of the core and ext JavaScript files. This was
created manually but a script to create one automatically wouldn't be
too much of a big thing either.
This should make working on especially the Node polyfills much more
pleasant, as it gives you feedback on if your imports are correct.
Unfortunately the TypeScript declaration files of some of the internal
modules clash with the import map and override the data from the actual
files with data from the declaration files. Those do not contain all
exports nor is their data always up to date. Still, this is much better
than not having one.
Follow up to https://github.com/denoland/deno/pull/19084.
This commit adds support for globs in the configuration file as well
as CLI arguments for files.
With this change users can now use glob syntax for "include" and
"exclude" fields, like so:
```json
{
"lint": {
"include": [
"directory/test*.ts",
"other_dir/"
],
"exclude": [
"other_dir/foo*.ts",
"nested/nested2/*"
]
},
"test": {
"include": [
"data/test*.ts",
"nested/",
"tests/test[1-9].ts"
],
"exclude": [
"nested/foo?.ts",
"nested/nested2/*"
]
}
}
```
Or in CLI args like so:
```
// notice quotes here; these values will be passed to Deno verbatim
// and deno will perform glob expansion
$ deno fmt --ignore="data/*.ts"
$ deno lint "data/**/*.ts"
```

This commit reimplements most of "node:http" client APIs using
"ext/fetch".
There is some duplicated code and two removed Node compat tests that
will be fixed in follow up PRs.

Partially supersedes #19016.
This migrates `spawn` and `spawn_blocking` to `deno_core`, and removes
the requirement for `spawn` tasks to be `Send` given our single-threaded
executor.
While we don't need to technically do anything w/`spawn_blocking`, this
allows us to have a single `JoinHandle` type that works for both cases,
and allows us to more easily experiment with alternative
`spawn_blocking` implementations that do not require tokio (ie: rayon).

This speeds up WPT tests in two ways:
1. The `WebCryptoAPI` tests are slow, so create a parallel bucket for
each individual test instead of one for all the `WebCryptoAPI` tests.
2. If a test is expected to fail, use a shorter timeout (1 minute rather
than 4).
To make it easier to debug which tests are slowing us down.
Tests taking more than 5s have duration printed in red,
taking more than 1s in yellow and less than 1s are printed
without color.
This reverts commit a3529d0232.
This change made debugging Node tests very hard - `AssertionError` is
now printed as `[Circular *1]` giving no visibility what failed.
We need to align two implementations together and remove this one then.
This reverts commit 4c2269d64a.

This reverts commit 29fb7709ed.
This update introduced more flakiness to the tests on CI, we are going
to investigate and reland this update after Deno 1.32.0 is released.
This PR _**temporarily**_ removes WebGPU (which has behind the
`--unstable` flag in Deno), due to performance complications due to its
presence.
It will be brought back in the future; as a point of reference, Chrome
will ship WebGPU to stable on 26/04/2023.

This commit renames "deno_core::InternalModuleLoader" to
"ExtModuleLoader" and changes the specifiers used by the
modules loaded from this loader to "ext:".
"internal:" scheme was really ambiguous and it's more characters than
"ext:", which should result in slightly smaller snapshot size.
Closes https://github.com/denoland/deno/issues/18020
- relands #17872
- updates the timeouts to be re-configurable just for CI
- fixes `./tools/wpt.ts update`
- adds option not "ignore" during, applied to wpt epoch runs only
Adds two test files: "cli/tests/unit_node/process_test.ts" and
"cli/tests/unit_node/child_process_test.ts"

This PR refactors all internal js files (except core) to be written as
ES modules.
`__bootstrap`has been mostly replaced with static imports in form in
`internal:[path to file from repo root]`.
To specify if files are ESM, an `esm` method has been added to
`Extension`, similar to the `js` method.
A new ModuleLoader called `InternalModuleLoader` has been added to
enable the loading of internal specifiers, which is used in all
situations except when a snapshot is only loaded, and not a new one is
created from it.

The 1.30.1 release had a performance regression that would have been
caught by looking at the benchmarks page. This adds a pre-flight step to
the release checklist for the person doing the release to go to this
page and look at the output.
This would have prevented #17629
This commit removes "Deno.core" namespace. It is strictly private API
that has no stability guarantees, we were supposed to remove it long time ago.

Updated third_party dlint to v0.37.0 for GitHub Actions. This PR
includes following changes:
* fix(prefer-primordials): Stop using array pattern assignments
* fix(prefer-primordials): Stop using global intrinsics except for
`SharedArrayBuffer`
* feat(guard-for-in): Apply new guard-for-in rule
Previously the inner request object of the original and the new request
were the same, causing the requests to be entangled and mutable changes
to one to be visible to the other. This fixes that.
Since "Deno.spawn()", "Deno.spawnSync()" and "Deno.spawnChild"
are getting deprecated, this commits rewrites all tests and utilities to
use "Deno.Command" API instead.
Implements fast scheduling of deferred op futures.
```rs
#[op(fast)]
async fn op_read(
state: Rc<RefCell<OpState>>,
rid: ResourceId,
buf: &mut [u8],
) -> Result<u32, Error> {
// ...
}
```
The future is scheduled via a fast API call and polled by the event loop
after being woken up by its waker.
