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
Closes https://github.com/denoland/deno/issues/25321
Ended up being a larger refactoring, since we're now juggling
(potentially) two config files in the same `add`, instead of choosing
one. I don't love the shape of the code, but I think it's good enough
Some smaller side improvements:
- `deno remove` supports `jsonc`
- `deno install --dev` will be a really simple change
- if `deno remove` removes the last import/dependency in the
`imports`/`dependencies`/`devDependencies` field, it removes the field
instead of leaving an empty object
The `.parse()` calls in permission code are only making it more
confusing, verbosity
is encouraged and welcome in this code even at the cost of not being
concise.
Left a couple TODOs to not use `AnyError`.
The map field has been empty for years now and we don't want the emit
file to be exposed so it allows us to iterate on making the cache
faster. Additionally, it's racy/unreliable to rely on this information.
Instead, people should emit the TS files themselves using tools like
deno_emit, typescript, esbuild, etc.

info: Deno doesn't support CommonJS modules without `.cjs` extension.
hint: Rewrite this module to ESM or change the file extension to `.cjs`.
```
This commit adds support for executing top-level `.cjs` files,
as well as import `.cjs` files from within npm packages.
This works only for `.cjs` files, the contents of sibling `package.json`
are not consulted for the `"type"` field.

The property names of the `exports` field in `deno.json` was never
validated. The `patternProperties` only validates values, whose property
name matches the regex. It doesn't validate the property names
themselves. That's what `propertyNames` is for.

This allows using npm deps of jsr deps without having to add them to the
root package.json.
Works by taking the package requirement and scanning the
`node_modules/.deno` directory for the best matching package, so it
relies on deno's node_modules structure.
Additionally to make the transition from package.json to deno.json
easier, Deno now:
1. Installs npm deps in a deno.json at the same time as installing npm
deps from a package.json.
2. Uses the alias in the import map for `node_modules/<alias>` for
better package.json compatiblity.
These now works:
```
$ deno add @std/dotenv/load
$ deno add npm:preact/hooks
```
Previously we were erroring out, because this is a "package reference"
including
a subpath.

`--allow-run` even with an allow list has essentially been
`--allow-all`... this locks it down more.
1. Resolves allow list for `--allow-run=` on startup to an absolute
path, then uses these paths when evaluating if a command can execute.
Also, adds these paths to `--deny-write`
1. Resolves the environment (cwd and env vars) before evaluating
permissions and before executing a command. Then uses this environment
to evaluate the permissions and then evaluate the command.
Fixes https://github.com/denoland/deno/issues/25333.
We fall back to junctions if the error kind is `PermissionDenied` but
the std library actually sets the kind to `Uncategorized` if the symlink
fails due to insufficient privileges. This was causing the fallback to
not actually fall back in this case.
Remove `--allow-hrtime` and `--deny-hrtime`. We are doing this because
it is already possible to get access to high resolution timers through
workers and SharedArrayBuffer.

This commit hides following unstable flags:
- `--unstable-ffi` (the API is now stable)
- `--unstable-webgpu` (this API is now stable)
- `--unstable-fs` (no more unstable APIs)
- `--unstable-byonm` (BYONM is on by default)
The flags are still parseable, but they are not used. Concrete cleanup
will be done in a follow up PR.
This significantly simplifies the types for `Deno.serve`.
The following types become generic over the address type:
- ServeHandlerInfo
- ServeHandler
- ServeOptions
- ServeInit
The following types are removed entirely:
- ServeTlsOptions
- ServeUnixOptions
- ServeUnixHandlerInfo
- ServeUnixHandler
Note: this is implemented on Deploy. However, according to @magurotuna,
a thin compatibility layer might be in the works that'd prevent
breakages for PRs such as this one.

Also updates help text to use "shorthand version" without flags, but a
positional arg.
This commit effectively turns Deno into Deno 2.0.
This is done by forcing `DENO_FUTURE=1` env var, that was available in
the past few months to try Deno 2 changes.
This commit contains several breaking changes scheduled for Deno 2:
- all deprecated JavaScript APIs are not available any more, mostly
`Deno.*` APIs
- `window` global is removed
- FFI, WebGPU and FS APIs are now stable and don't require
`--unstable-*` flags
- import assertions are no longer supported
- "bring your own node modules" is enabled by default
This is the first commit in a series that are scheduled before the Deno
2 release.

Fixes an incredibly obscure bug that causes parcel's file watcher to not
get any file update notifications on macOS.
The issue was that the native addon was calling `napi_resolve_deferred`,
but when we resolved the promise, v8 was running microtasks
automatically. That executed JS, which called back into the native addon
and broke the addon's assumption that the call wouldn't be reentrant.
Stores normalized version constraints in the lockfile, which will
improve reproducibility and will fix a bug with duplicate specifiers
ending up in the lockfile. Also, gets rid of some duplicate data in the
specifiers area of the lockfile.
Unlike in dprint, `single_quote` option is shared between all
formatters, so we shouldn't change this option when formatting
attributes in components. This PR fixes this.
This problem doesn't affect formatting HTML.
This commit remove `--lock-write` that was deprecated in v1.45 release.

This commit deprecates "import assertions" proposal that has been
replaced with "import attributes".
Any time an import assertion is encountered a warning will be printed
to the terminal. This warning will be printed for both local and
remote files (ie. user code and dependencies).
Import assertions support will be removed in Deno 2.
This commit changes `deno upgrade` subcommand to accept
a positional argument that can be either a version, release channel
name or a git hash, making invocations of `deno upgrade` much
more concise:
```
# before
$ deno upgrade --version 1.46.0
# after
$ deno upgrade 1.46.0
```
```
# before
$ deno upgrade --canary
# after
$ deno upgrade canary
```
```
# specific canary version before
$ deno upgrade --canary --version f042c39180
# after
$ deno upgrade f042c39180
```
Old flags are still supported, but hidden from the help output.
- Update ffi turbocall to use revised fast call api
- Remove `v8_version` function calls
- `*mut OwnedIsolate` is no longer stored in OpCtx gotham store
Permission flags are unified in a clearer and concise output.
Unstable flags are hidden by default with exception of the `unstable`
flag itself. the remaining unstable flags can be seen with a
`--help=unstable`.
This also cleans up to show unstable flags only for subcommands that
actually need them.
Also sorts flags alphabetically, and gorups various flags together in a
set of categories.

This commit fixes computation of the latest available version
by taking into account which release channel the current
binary is on.
Before this commit, if user was on "RC" channel, calling
`deno upgrade` would not switch back to the "stable"
channel.
This commits add a CI script that allows to promote a certain
canary build to a "Release Candidate" release.
This is done using `libsui` and `patchver` utilities.
This change improves the Node.js compatibility in managed npm resolution
mode by disabling the discovery of `node_modules` when the
main specifier is inside of `DENO_DIR`.
closes #22732
closes #24589
This commit rewrites the internal `version` module that exported
various information about the current executable. Instead of exporting
several consts, we are now exporting a single const structure that
contains all the necessary information.
This is the first step towards cleaning up how we use this information
and should allow us to use SUI to be able to patch this information
in already produced binary making it easier to cut new releases.

From upgrading `deno_lint`.
Previously if you had a node project that used a bunch of node globals
(`process.env`, etc), you would have to fix the errors by hand. This PR
includes a new lint that detects usages of node globals (`process`,
`setImmediate`, `Buffer`, etc.) and provides an autofix to import the
correct value. For instance:
```ts
// main.ts
const _foo = process.env.FOO;
```
`deno lint` gives you
```ts
error[no-node-globals]: NodeJS globals are not available in Deno
--> /home/foo.ts:1:14
|
1 | const _foo = process.env.FOO;
| ^^^^^^^
= hint: Add `import process from "node:process";`
docs: https://lint.deno.land/rules/no-node-globals
Found 1 problem (1 fixable via --fix)
Checked 1 file
```
And `deno lint --fix` adds the import for you:
```ts
// main.ts
import process from "node:process";
const _foo = process.env.FOO;
```
In preparation for https://github.com/denoland/deno/pull/25014, this
commit removes public `is_canary()` method and instead uses an enum
`ReleaseChannel` to be able to designate more "kinds" of builds.
Adds a `parallel` flag to `deno serve`. When present, we spawn multiple
workers to parallelize serving requests.
```bash
deno serve --parallel main.ts
```
Currently on linux we use `SO_REUSEPORT` and rely on the fact that the
kernel will distribute connections in a round-robin manner.
On mac and windows, we sort of emulate this by cloning the underlying
file descriptor and passing a handle to each worker. The connections
will not be guaranteed to be fairly distributed (and in practice almost
certainly won't be), but the distribution is still spread enough to
provide a significant performance increase.

These errors are caused by the fact that the test server doesn't have an
endpoint to return
RC releases. Which in turn causes an error to be raised which later just
short-circuits logic
for checking the version and storing it in file. Since fetching from a
remote host is always
fallible I elected to just return an empty vec of "rc" versions instead
of erroring. This might
lead to a slight mismatch in some situation when the request actually
failed and user is
prompted that there's a new canary version, but that is better than not
displaying
prompt at all. This issue will be fixed more robustly once we move to
using SUI for
specifying version of the binary.
This commit adds the "--rc" flag to "deno upgrade" subcommand.
This flag allows to upgrade to the latest "release candidate" release.
The update checker was also updated to take this into account.
This commit stabilizes HMR functionality and renames

flag is still working, but hidden from the help output.
It will be removed in Deno 2.
Once https://github.com/denoland/deno/pull/24958 lands
we should improve grouping of `--watch` and `--watch-hmr`
flags.

This PR ensures that we forward a `rename` event in our file watcher.
The rust lib we use combines that with the `modify` event.
This fixes a compatibility issue with Node too, which sends the `rename`

This PR updates `deno run` to fallback to executing tasks when there is
no script with the specified name. If there are both script and a task
with the same name then `deno run` will prioritise executing the script.
This moves YAML formatting behind an unstable flag for Deno 1.46. This
will make it opt-in to start and then we can remove the flag to make it
on by default in version of Deno after that.
This can be specified by doing `deno fmt --unstable-yaml` or by
specifying the following in a deno.json file:
```json
{
"unstable": ["fmt-yaml"]
}
```

This PR resolves a handful of issues with child_process IPC. In
particular:
- We didn't support sending typed array views over IPC
- Opening an IPC channel resulted in the event loop never exiting
- Sending a `null` over IPC would terminate the channel
- There was some UB in the read implementation (transmuting an `&[u8]`
to `&mut [u8]`)
- The `send` method wasn't returning anything, so there was no way to
signal backpressure (this also resulted in the benchmark
`child_process_ipc.mjs` being misleading, as it tried to respect
backpressure. That gave node much worse results at larger message sizes,
and gave us much worse results at smaller message sizes).
- We weren't setting up the `channel` property on the `process` global
(or on the `ChildProcess` object), and also didn't have a way to
ref/unref the channel
- Calling `kill` multiple times (or disconnecting the channel, then
calling kill) would throw an error
- Node couldn't spawn a deno subprocess and communicate with it over IPC
