This PR optimizes the case when `performance.measure()` needs to find
the startMark by name. It is a simple change on `findMostRecent` fn to
avoiding copying and reversing the complete entries list.
Adds minor missing tests for:
- `clearMarks()`, general
- `clearMeasures()`, general
- `measure()`, case when the startMarks name exists more than once

Fixes rsbuild running in deno.
You can look at the test to see what was failing, the gist is that we
were trying to statically analyze the re-exports of a CJS script, and if
we couldn't find the source for the re-exported file we would fail.
Instead, we should just treat these as if they were too dynamic to
analyze, and let it fail (or succeed) at runtime. This aligns with
node's behavior.
Aligns the error messages in the ext/http and a few messages in the
ext/fetch folder to be in-line with the Deno style guide.
This change-set also removes some unnecessary checks in the 00_serve.ts.
These options were recently removed, so it doesn't make sense to check
for them anymore.

This commit lets `deno test --doc` command actually evaluate code snippets in
JSDoc and markdown files.
## How it works
1. Extract code snippets from JSDoc or code fences
2. Convert them into pseudo files by wrapping them in `Deno.test(...)`
3. Register the pseudo files as in-memory files
4. Run type-check and evaluation
We apply some magic at the step 2 - let's say we have the following file named
`mod.ts` as an input:
````ts
/**
* ```ts
* import { assertEquals } from "jsr:@std/assert/equals";
*
* assertEquals(add(1, 2), 3);
* ```
*/
export function add(a: number, b: number) {
return a + b;
}
````
This is virtually transformed into:
```ts
import { assertEquals } from "jsr:@std/assert/equals";
import { add } from "files:///path/to/mod.ts";
Deno.test("mod.ts$2-7.ts", async () => {
assertEquals(add(1, 2), 3);
});
```
Note that a new import statement is inserted here to make `add` function
available. In a nutshell, all items exported from `mod.ts` become available in
the generated pseudo file with this automatic import insertion.
The intention behind this design is that, from library user's standpoint, it
should be very obvious that this `add` function is what this example code is
attached to. Also, if there is an explicit import statement like
`import { add } from "./mod.ts"`, this import path `./mod.ts` is not helpful for
doc readers because they will need to import it in a different way.
The automatic import insertion has some edge cases, in particular where there is
a local variable in a snippet with the same name as one of the exported items.
This case is addressed by employing swc's scope analysis (see test cases for
more details).
## "type-checking only" mode stays around
This change will likely impact a lot of existing doc tests in the ecosystem
because some doc tests rely on the fact that they are not evaluated - some cause
side effects if executed, some throw errors at runtime although they do pass the
type check, etc. To help those tests gradually transition to the ones runnable
with the new `deno test --doc`, we will keep providing the ability to run
type-checking only via `deno check --doc`. Additionally there is a `--doc-only`
option added to the `check` subcommand too, which is useful when you want to
type-check on code snippets in markdown files, as normal `deno check` command
doesn't accept markdown.

This fixes the fast path for `readableStreamCollectIntoUint8Array` to
only trigger if the readable stream has not yet been disturbed -
because otherwise we may not be able to close it if the
read errors.
Fixes https://github.com/denoland/deno/issues/25632
Exit code 1 indiciates some sort of failure but `deno task` (without
arguments) is used to list available commands.

This commit fixes the error format when the cause is assigned
separately, ensuring that the cause is only printed once instead of
twice.
The fix addresses issue
[#21651](https://github.com/denoland/deno/issues/21651).
Closes #20613.
Reimplements the serialization on top of the v8 APIs instead of
deno_core. Implements `v8.Serializer`, `v8.DefaultSerializer`,
`v8.Deserializer`, and `v8.DefaultSerializer`.
implement require(esm) using `op_import_sync` from deno_core.
possible future changes:
- cts and mts
- replace Deno.core.evalContext to optimize esm syntax detection
Fixes: https://github.com/denoland/deno/issues/25487
This commit removes all occurrences of `--unstable` flag
from all the tests that are run in CI.
Turns out none of the tests actually required that flag
anymore.
This PR addresses issue #25534
**Code Changes**
- Updated malva version to the latest in cli/Cargo.toml.
- Updated LanguageOptions to match new Malva config.
- Added test case same as the issue to assure changes success.
This commit improves error messages for unstable APIs:
- `--unstable-broadcast-channel`
- `--unstable-cron`
- `--unstable-http`
- `--unstable-kv`
- `--unstable-temporal`
By providing information and hints what went wrong and how the
error can be fixed. It reuses the same infra that was added in
https://github.com/denoland/deno/pull/21764.
This was initially added in #25399 in order to make transitioning over
from package.json to deno.json more easy, but it causes some problems
that are shown in the issue and it also means that the output of `deno
install` would have different resolution than `npm install`. Overall, I
think it's too much complexity to be smarter about this and it's
probably best to not do it. If someone needs an aliased folder then they
should keep using a package.json
Closes #25538
The long form "files" config has been flattened into the parent.
Old:
```json
{
"test": {
"files": {
"include": ["**/*.ts"],
"exclude": ["ignore.ts"]
}
}
}
```
New:
```json
{
"test": {
"include": ["**/*.ts"],
"exclude": ["ignore.ts"]
}
}
```
This was deprecated some time ago, but we're removing it now in Deno
2.0.
Closes #25415
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
