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).

Fixes https://github.com/denoland/deno/issues/21594
I verified locally that this fixes the problem. I'm working on testing
harness for Jupyter kernel to catch regressions like this and will
add it in a follow up PR.
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.
Adds an `--unstable-sloppy-imports` flag which supports the
following for `file:` specifiers:
* Allows writing `./mod` in a specifier to do extension probing.
- ex. `import { Example } from "./example"` instead of `import { Example
} from "./example.ts"`
* Allows writing `./routes` to do directory extension probing for files
like `./routes/index.ts`
* Allows writing `./mod.js` for *mod.ts* files.
This functionality is **NOT RECOMMENDED** for general use with Deno:
1. It's not as optimal for perf:
https://marvinh.dev/blog/speeding-up-javascript-ecosystem-part-2/
1. It makes tooling in the ecosystem more complex in order to have to
understand this.
1. The "Deno way" is to be explicit about what you're doing. It's better
in the long run.
1. It doesn't work if published to the Deno registry because doing stuff
like extension probing with remote specifiers would be incredibly slow.
This is instead only recommended to help with migrating existing
projects to Deno. For example, it's very useful for getting CJS projects
written with import/export declaration working in Deno without modifying
module specifiers and for supporting TS ESM projects written with
`./mod.js` specifiers.
This feature will output warnings to guide the user towards correcting
their specifiers. Additionally, quick fixes are provided in the LSP to
update these specifiers:
A bit hacky, but it works. Essentially, this will check for all the
scripts in the node_modules/.bin directory then force them to run with
Deno via deno_task_shell.
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
```

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.
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.
This commit adds `--unstable-hmr` flag, that enabled Hot Module Replacement.
This flag works like `--watch` and accepts the same arguments. If
HMR is not possible the process will be restarted instead.
Currently HMR is only supported in `deno run` subcommand.
Upon HMR a `CustomEvent("hmr")` will be dispatched that contains
information which file was changed in its `details` property.

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.
This commit moves `snapshot_from_lockfile` function to [deno_npm
crate](https://github.com/denoland/deno_npm). This allows this function
to be called outside Deno CLI (in particular, Deno Deploy).
Renames the unstable `deno_modules` directory and corresponding settings
to `vendor` after feedback. Also causes the vendoring of the
`node_modules` directory which can be disabled via
`--node-modules-dir=false` or `"nodeModulesDir": false`.
This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.
These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.
Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.
Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.
Closes #18804.

This commit adds a "dot" reporter to "deno test" subcommand,
that can be activated using "--dot" flag.
It provides a concise output using:
- "." for passing test
- "," for ignored test
- "!" for failing test
User output is silenced and not printed to the console.
In non-TTY environments each result is printed on a separate line.
This commit makes the following changes
- Created a `CompoundTestReporter` to allow us to use multiple reporters
- Implements `JUnitTestReporter` which writes JUnit XML to a path
- Added a CLI flag/option `--junit` that enables JUnit reporting. By
default this writes the report to `stdout` (and disables pretty
reporting). If a path is provided, it will write the JUnit report to
that file while the pretty reporter writes to stdout like normal

This prevents documents specified in a deno.json's "exclude" from being
pre-loaded by the lsp.
For example, someone may have something like:
```jsonc
// deno.json
{
"exclude": [
"dist" // build directory
]
}
```
I'm unsure why we canonicalize the config file path when loading and the
canonicalization is causing issues in #19431 because everything in the
lsp is not canonicalized except the config file (actually, the config
file is only canonicalized when auto-discovered and not whens pecified).
We also don't canonicalize module paths when loading them.
Canonicalization was added in https://github.com/denoland/deno/pull/7621
Before:
```
$ cargo run -- test "foo/*******/bar.ts"
error: Pattern syntax error near position 6: wildcards are either regular `*` or recursive `**`
```
After:
```
$ cargo run -- test "foo/*******/bar.ts"
error: Failed to expand glob: "foo/*******/bar.ts"
Caused by:
Pattern syntax error near position 6: wildcards are either regular `*` or recursive `**`

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"
```
Closes https://github.com/denoland/deno/issues/17971
Closes https://github.com/denoland/deno/issues/6365
This adds support for the lockfile and node_modules directory to the
lsp.
In the case of the node_modules directory, it is only enabled when
explicitly opted into via `"nodeModulesDir": true` in the configuration
file. This is to reduce the language server automatically modifying the
node_modules directory when the user doesn't want it to.
Closes #16510
Closes #16373
We never properly added support for this. This fixes vendoring when it
has npm or node specifiers. Vendoring occurs by adding a
`"nodeModulesDir": true` property to deno.json then it uses a local
node_modules directory. This can be opted out by setting
`"nodeModulesDir": false` or running with `--node-modules-dir=false`.
Closes #18090
Closes #17210
Closes #17619
Closes #16778
Note: If the package information has already been cached, then this
requires running with `--reload` or for the registry information to be
fetched some other way (ex. the cache busting).
Closes #15544
