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.
Follow up work is tracked in
https://github.com/denoland/deno/issues/25241.

This is blocking https://github.com/denoland/deno/pull/25213.
Turns out a bunch of FS APIs are completely broken because they
use RIDs (resource IDs) instead of FDs (file descriptors).
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.
This commit remove `--lock-write` that was deprecated in v1.45 release.
Closes https://github.com/denoland/deno/issues/24167.

- Add missing exports to `node:cluster`
- Fix default export not being an instance of `EventEmitter`
- Fix aliasing of properties
- Fix `disconnected` -> `disconnect` export naming
This makes `log4js` work in Deno. `karma` starts too, but somehow the
server isn't responding. That looks like a different issue.
Fixes https://github.com/denoland/deno/issues/24858
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.

MacOS tends to not distribute evenly, so just don't assert that requests
were served by > 1 worker on mac.
Also added a check that all workers start, so we at least check that on
macos.
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.

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 change aims to replace all relative import specifiers targeted at
`tests/util/std` with mapped ones (using a `deno.json` file). Towards
updating the `std` git submodule.
Two small changes:
- In our BYONM errors, suggest running `deno install` instead of `npm
install` if `DENO_FUTURE` is set
- Only emit warning about `deno install` changes if you do `deno install
<foo>` with deno_future unset

Currently, importing Node-Addons modules in a standalone binary results
in a `missing symbol called` error
(https://github.com/denoland/deno/issues/24614). Because the NAPI
symbols are not exported in this mode. This PR should fix the issue.
Originally landed in
f6fd6619e7.
Reverted in https://github.com/denoland/deno/pull/24574.
This reland contains a fix that sends "Accept: */*" header for calls made
from "FileFetcher". Absence of this header made downloading source code
from JSR broken. This is tested by ensuring this header is present in the
test server that servers JSR packages.

This commit re-implements `ext/fetch` and all dependent crates
using `hyper` and `hyper-util`, instead of `reqwest`.

as `node:http` module.

Adds support for running npm package lifecycle scripts, opted into via a
new `--allow-scripts` flag.
With this PR, when running `deno cache` (or `DENO_FUTURE=1 deno
install`) you can specify the `--allow-scripts=pkg1,pkg2` flag to run
lifecycle scripts attached to the given packages.
Note at the moment this only works when `nodeModulesDir` is true (using
the local resolver).
When a package with un-run lifecycle scripts is encountered, we emit a
warning suggesting things may not work and to try running lifecycle
scripts. Additionally, if a package script implicitly requires
`node-gyp` and it's not found on the system, we emit a warning.
Extra things in this PR:
- Extracted out bits of `task.rs` into a separate module for reuse
- Added a couple fields to `process.config` in order to support
`node-gyp` (it relies on a few variables being there)
- Drive by fix to downloading new npm packages to test registry
---
TODO:
- [x] validation for allow-scripts args (make sure it looks like an npm
package)
- [x] make allow-scripts matching smarter
- [ ] figure out what issues this closes
---
Review notes:
- This adds a bunch of deps to our test registry due to using
`node-gyp`, so it's pretty noisy
This commit deprecates `deno vendor` subcommand in favor
of using `--vendor` flag or `"vendor": true` setting in the config file.
The subcommand is still available (until Deno 2) but is hidden from
the help output.

The implementation for `assert.throws()` from `node:assert` didn't work
when the expected value was an `Error` constructor. In this case the
thrown error should checked if it's an instance of said constructor.

Previously we had many different code paths all
handling digests in different places, all with
wildly different digest support. This commit
rewrites this to use a single digest handling
mechanism for all digest operations.
It adds various aliases for digest algorithms,
like node does. For example
`sha1WithRSAEncryption` is an alias for `sha1`.
It also adds support for `md5-sha1` digests in
various places.
Adds much better support for the unstable Deno workspaces as well as
support for npm workspaces. npm workspaces is still lacking in that we
only install packages into the root node_modules folder. We'll make it
smarter over time in order for it to figure out when to add node_modules
folders within packages.
This includes a breaking change in config file resolution where we stop
searching for config files on the first found package.json unless it's
in a workspace. For the previous behaviour, the root deno.json needs to
be updated to be a workspace by adding `"workspace":
["./path-to-pkg-json-folder-goes-here"]`. See details in
https://github.com/denoland/deno_config/pull/66

This commit updates Deno to use `reqwest` at 0.12.4
and `rustls` at 0.22. Other related crates were updated
as well to match versions accepted by `reqwest` and `rustls`.
Note: we are not using the latest available `rustls` yet,
but this upgrade was non-trivial already, so a bump to
0.23 for `rustls` will be done in a separate commit.

In https://github.com/denoland/deno/pull/23955 we changed the sqlite db

This patch fixes stdin read hanging on user input when switching tty

Fixes #21111
On Windows, when switching from line to raw mode:
- Cancel ongoing console read by writing a return keypress to its input
buffer. This blocks the main thread until any ongoing read has been
cancelled to prevent interference with the screen state.
- On the read thread, restore the cursor position to where it was before
writing the enter, undoing its effect on the screen state.
- Restart reading and notify the main thread.

This commit adds initial support for ".npmrc" files.
Currently we only discover ".npmrc" files next to "package.json" files
and discovering these files in user home dir is left for a follow up.
This pass supports "_authToken" and "_auth" configuration
for providing authentication.
LSP support has been left for a follow up PR.
Towards https://github.com/denoland/deno/issues/16105
Fixes #23571.
Previously, we required a `deno.json` to be present (or the `--lock`
flag) in order for us to resolve a `deno.lock` file. This meant that if
you were using deno in an npm-first project deno wouldn't use a
lockfile.
Additionally, while I was fixing that, I discovered there were a couple
bugs keeping the future `install` command from using a lockfile.
With this PR, `install` will actually resolve the lockfile (or create
one if not present), and update it if it's not up-to-date. This also
speeds up `deno install`, as we can use the lockfile to skip work during
npm resolution.
This PR removes the use of the custom `utc_now` function in favor of the
`chrono` implementation. It resolves #22864.

This brings in [`runtimelib`](https://github.com/runtimed/runtimed) to
use:
## Fully typed structs for Jupyter Messages
```rust
let msg = connection.read().await?;
self
.send_iopub(
runtimelib::Status::busy().as_child_of(msg),
)
.await?;
```
## Jupyter paths
Jupyter paths are implemented in Rust, allowing the Deno kernel to be
installed completely via Deno without a requirement on Python or
Jupyter. Deno users will be able to install and use the kernel with just
VS Code or other editors that support Jupyter.
```rust
pub fn status() -> Result<(), AnyError> {
let user_data_dir = user_data_dir()?;
let kernel_spec_dir_path = user_data_dir.join("kernels").join("deno");
let kernel_spec_path = kernel_spec_dir_path.join("kernel.json");
if kernel_spec_path.exists() {
log::info!("✅ Deno kernel already installed");
Ok(())
} else {
log::warn!("ℹ️ Deno kernel is not yet installed, run `deno jupyter --install` to set it up");
Ok(())
}
}
```
Closes https://github.com/denoland/deno/issues/21619
The stderr stream from the LSP is consumed by a separate thread, so it
may not have processed the part we care about yet. Instead, wait until
you see the measure for the request you care about.
VScode will typically send a `textDocument/semanticTokens/full` request
followed by `textDocument/semanticTokens/range`, and occassionally
request semantic tokens even when we know nothing has changed. Semantic
tokens also get refreshed on each change. Computing semantic tokens is
relatively heavy in TSC, so we should avoid it as much as possible.
Caches the semantic tokens for open documents, to avoid making TSC do
unnecessary work. Results in a noticeable improvement in local

This implements the SNI features, but uses private symbols to avoid
exposing the functionality at this time. Note that to properly test this
feature, we need to add a way for `connectTls` to specify a hostname.
This is something that should be pushed into that API at a later time as
well.
```ts
Deno.test(
{ permissions: { net: true, read: true } },
async function listenResolver() {
let sniRequests = [];
const listener = Deno.listenTls({
hostname: "localhost",
port: 0,
[resolverSymbol]: (sni: string) => {
sniRequests.push(sni);
return {
cert,
key,
};
},
});
{
const conn = await Deno.connectTls({
hostname: "localhost",
[serverNameSymbol]: "server-1",
port: listener.addr.port,
});
const [_handshake, serverConn] = await Promise.all([
conn.handshake(),
listener.accept(),
]);
conn.close();
serverConn.close();
}
{

1. Generally we should prefer to use the `log` crate.
2. I very often accidentally commit `eprintln`s.
When we should use `println` or `eprintln`, it's not too bad to be a bit
more verbose and ignore the lint rule.
Fixes the `Debug Failure` errors described in
https://github.com/denoland/deno/issues/23643#issuecomment-2094552765 .
The issue here was that we were passing diagnostic codes as strings but
TSC expects the codes to be numbers. This resulted in some quick fixes
not working (as illustrated by the test added here which fails before
this PR).
The first commit is the actual fix. The rest are just test related.
A bunch of small things, mostly around timing and making sure the
jupyter kernel is actually running and ready to respond to requests. I
reproduced the flakiness by running a script to run a bunch of instances
of the test in parallel, where I could get failures consistently. After
this PR, I can't reproduce the flakiness locally which hopefully means
that applies to CI as well
