This PR fixes #21658.
- `check` subcommand sees `exclude` option in `deno.json`. When some
paths passed with `check` command listed in `exclude`, they are ignored.
- When some files are listed in `exclude` and imported indirectly among
module graph, they are checked.
Harden the code that does permission checks to protect against
re-opening of stdin.
Code that runs FFI is vulnerable to an attack where fd 0 is closed
during a permission check and re-opened with a file that contains a
positive response (ie: `y` or `A`). While FFI code is dangerous in
general, we can make it more difficult for FFI-enabled code to bypass
additional permission checks.
- Checks to see if the underlying file for stdin has changed from the
start to the end of the permission check (detects races)
- Checks to see if the message is excessively long (lowering the window
for races)
- Checks to see if stdin and stderr are still terminals at the end of
the function (making races more difficult)
This problem occurred trying to load tensorflow.js

Uncaught SyntaxError: Identifier 'mod' has already been declared at file:///Users/ry/Library/Caches/deno/npm/registry.npmjs.org/@tensorflow/tfjs/4.14.0/dist/tf.node.js:167:14

This fixes #21434 for `BroadcastChannel` and `WebSocketStream`.
`--unstable` still enable both, but granular unstable flags now also
work:
* `--unstable-net` now enables `WebSocketStream`.
* `--unstable-broadcast-channel` now enables `BroadcastChannel`.
* Additionally, there are now tests for all granular unstable flags.
Since `unsafe-proto` already had tests, so I didn't add any for this
one.
It also introduces a map to keep track of granular unstable ids without
having to sync multiple places.
Landing changes required for
https://github.com/denoland/deno_core/pull/359
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.
This PR causes Deno to include more files in the graph based on how a
template literal looks that's provided to a dynamic import:
```ts
const file = await import(`./dir/${expr}`);
```
In this case, it will search the `dir` directory and descendant
directories for any .js/jsx/etc modules and include them in the graph.
To opt out of this behaviour, move the template literal to a separate
line:
```ts
const specifier = `./dir/${expr}`
const file = await import(specifier);
```
This commit adds unstable workspace support. This is extremely
bare-bones and
minimal first-pass at this.
With this change `deno.json` supports specifying `workspaces` key, that
accepts a list of subdirectories. Each workspace can have its own import
map. It's required to specify a `"name"` and `"version"` properties in the
configuration file for the workspace:
```jsonc
// deno.json
{
"workspaces": [
"a",
"b"
},
"imports": {
"express": "npm:express@5"
}
}
```
``` jsonc
// a/deno.json
{
"name": "a",
"version": "1.0.2",
"imports": {
"kleur": "npm:kleur"
}
}
```
```jsonc
// b/deno.json
{
"name": "b",
"version": "0.51.0",
"imports": {
"chalk": "npm:chalk"
}
}
```
`--unstable-workspaces` flag is required to use this feature:
```
$ deno run --unstable-workspaces mod.ts
```

Fixes #21121 and #19498
Migrates fully to rustls_tokio_stream. We no longer need to maintain our
own TlsStream implementation to properly support duplex.
This should fix a number of errors with TLS and websockets, HTTP and
"other" places where it's failing.
This also updates deno_graph, which has the JSR change to use "exports".
It's not yet useful atm, so I've made this PR a fix about the deno doc
--lint error message improvements. I'll do a follow-up PR that adds
exports to the deno.json
As pointed out in https://github.com/denoland/deno/issues/21067 , it's
confusing that `deno doc --lint mod.ts` outputs the documentation to
stdout on success. Instead, it would be better if it outputted how many
files were checked similar to what `deno lint` does on success. It still
outputs the documentation if `--lint` or `--html` are provided so this
is non-breaking.
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:
https://github.com/web-platform-tests/wpt/issues/42896
This change adds the `--env=[FILE]` flag to the `run`, `compile`,
`eval`, `install` and `repl` subcommands. Environment variables set in
the CLI overwrite those defined in the `.env` file.
Adds a new `--lint` flag to `deno doc` that surfaces three kinds of
diagnostics:
1. Diagnostic for non-exported type referenced in an exported type.
* Why? People often forget to export types from a module in TypeScript.
To supress this diagnostic, add an `@internal` jsdoc tag to the internal
type.
1. Diagnostic for missing return type or missing property type on a
**public** type.
* Why? Otherwise `deno doc` will not display good documentation. Adding
explicit types also helps with type checking performance.
1. Diagnostic for missing jsdoc on a **public** type.
* Why? Everything should be documented. This diagnostic can be supressed
by adding a jsdoc comment description.
If the lint passes, `deno doc` generates documentation as usual.
For example, checking for deno doc diagnostics on the CI:
```shellsession
$ deno doc --lint mod.ts second_entrypoint.ts > /dev/null
```
This feature is incredibly useful for library authors.
## Why not include this in `deno lint`?
1. The command needs the documenation output in order to figure out the
diagnostics.
1. `deno lint` doesn't understand where the entrypoints are. That's
critical for the diagnostics to be useful.
1. It's much more performant to do this while generating documentation.
1. There is precedence in rustdoc (ex. `#![warn(missing_docs)]`).
## Why not `--check`?
It is confusing with `deno run --check`, since that means to run type
checking (and confusing with `deno check --docs`).
## Output Future Improvement
The output is not ideal atm, but it's fine for a first pass. We will
improve it in the future.
Closes https://github.com/denoland/deno_lint/pull/972
Closes https://github.com/denoland/deno_lint/issues/970
Closes https://github.com/denoland/deno/issues/19356
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.
Believed to fix #20355, #18977, #20948
