This commit adds support for [TC39 Decorator
Proposal](https://github.com/tc39/proposal-decorators).
These decorators are only available in transpiled sources - ie.
non-JavaScript files (because of lack of support in V8).
This entails that "experimental TypeScript decorators" are not available
by default
and require to be configured, with a configuration like this:
```
{
"compilerOptions": {
"experimentalDecorators": true
}
}
```
Closes https://github.com/denoland/deno/issues/19160

This change sets the removal version for the `deno bundle` sub-command
for Deno v2. The warnings appear when `deno bundle` is run and in the
`--help` menu.
This change:
1. Implements `Deno.FsFile.sync()` and `Deno.FsFile.syncSync()`.
2. Deprecates `Deno.fsync()` and `Deno.fsyncSync()` for removal in Deno
v2, in favour of the above corresponding methods.

Most uses of `Deno.resources()` within tests, as they previously checked
for leaked resources. This is not needed as the test runner does this
automatically. Other internal uses of this API have been replaced with
the internal `Deno[Deno.internal].core.resources()`.
This change:
1. Implements `Deno.stdin.isTerminal()`, `Deno.stdout.isTerminal()` and
`Deno.stderr.isTerminal()`.
2. Deprecates `Deno.isatty()` for removal in Deno v2, in favour of the
above instance methods.
3. Replaces use of `Deno.isatty()` with the above instance methods.

This commit adds `import.meta.filename` and `import.meta.dirname` APIs.
These APIs return string representation of filename and containing
dirname.
They are only defined for local modules (modules that have `file:///`
scheme).
Example:
```ts
console.log(import.meta.filename, import.meta.dirname)
```
Unix:
```
$ deno run /dev/my_module.ts
/dev/my_module.ts /dev/
```
Windows:
```
$ deno run C:\dev\my_module.ts
C:\dev\my_module.ts C:\
```
This change sets the removal version of `Deno.customInspect` for Deno
v2.

It appears the `--prompt` flag has done nothing for some time. Perhaps,
since #13650. Classifying this as a dead functionality removal for this
reason.
Did this while working on #22021.
This change:
1. Sets the removal version for `Deno.ListenTlsOptions.certFile`,
`Deno.ListenTlsOptions.keyFile` and `Deno.ConnectTlsOptions.certFile`
for Deno v2, in favour of the `cert`, `key` and `caCerts` options,
respectively.
2. Replaces use of the deprecated options with the new recommended
options.
Towards #22021
This initially uses the new diagnostic printer in `deno lint`,
`deno doc` and `deno publish`. In the limit we should also update
`deno check` to use this printer.
This commit deprecates "--unstable" flag.
When "--unstable" flag is encountered a warning like this is printed:
```
The `--unstable` flag is deprecated, use granular `--unstable-*` flags instead.
Learn more at: https://docs.deno.com/runtime/manual/tools/unstable_flags
```
When "--unstable" flag is used and an unstable API is called an
additional warning like this is printed for each API call:
```
The `Deno.dlopen` API was used with `--unstable` flag. The `--unstable` flag is deprecated, use granular `--unstable-ffi` instead.
Learn more at: https://docs.deno.com/runtime/manual/tools/unstable_flags
```
When no "--unstable-*" flag is provided and an unstable API is called
following
warning is issued before exiting:
```
Unstable API 'Deno.dlopen'. The `--unstable-ffi` flag must be provided.
```

This change removes the currently deprecated `Deno.cron()` overload with
`options` as a potential last argument.
This might be fine to do now, in a major release, as `Deno.cron()` is an
unstable API. I thought of doing this while working on #22021. If this
is not ready to remove, I can instead set the removal version of this
overload for Deno v2.
Note: this overload was deprecated in Deno v1.38.2 (#21225). So it's
been deprecated for over 2 months.
This change:
1. Sets the removal version for `Deno.RequestEvent`, `Deno.HttpConn` and
`Deno.serveHttp()` for Deno v2. I thought it might be worth calling
`warnOnDeprecatedApi()` within `Deno.Request` and `Deno.HttpConn`
methods, but I thought just having it called within `Deno.serveHttp()`
might be sufficient.
2. Removes some possibly unneeded related benchmarks.
Towards #22021
Closes https://github.com/denoland/deno/issues/21828.
This API is a huge footgun. And given that "Deno.serveHttp" is a
deprecated API that is discouraged to use (use "Deno.serve()"
instead); it makes no sense to keep this API around.
This is a step towards fully migrating to Hyper 1.
Fixes #21928.
We have a code path which empties the extension sources because they're
expected to be pre-executed in the snapshot. Instead of using
conditional compilation for that, we now just check if a snapshot was
provided.
Removes the `dont_use_runtime_snapshot` feature. We didn't allow not
providing a snapshot unless this feature was provided, now we always do.
Adds the `only_snapshotted_js_sources` feature for us to use in CLI.
This asserts that a snapshot is provided and gates the runtime
transpilation code so it isn't included in the executable.
This change takes advantage of explicit resources management for
`FsFile` instances and tweaks documentation to encourage the use of it.

Ultimately, it came down to using incorrect property names in the

This commit introduces deprecation warnings for "Deno.*" APIs.
This is gonna be quite noisy, but should tremendously help with user
code updates to ensure
smooth migration to Deno 2.0. The warning is printed at each unique call
site to help quickly
identify where code needs to be adjusted. There's some stack frame
filtering going on to
remove frames that are not useful to the user and would only cause
confusion.
The warning can be silenced using "--quiet" flag or
"DENO_NO_DEPRECATION_WARNINGS" env var.
"Deno.run()" API is now using this warning. Other deprecated APIs will
start warning
in follow up PRs.
Example:
```js
import { runEcho as runEcho2 } from "http://localhost:4545/run/warn_on_deprecated_api/mod.ts";
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
async function runEcho() {
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
}
await runEcho();
await runEcho();
for (let i = 0; i < 10; i++) {
await runEcho();
}
await runEcho2();
```

This commit removes the requirement for `--unstable` flag in `deno
jupyter` subcommand. The process will no longer exit if this flag is not
provided, however the subcommand itself is still considered unstable
and might change in the future.

This commit removes conditional type-checking of unstable APIs.
Before this commit `deno check` (or any other type-checking command and
the LSP) would error out if there was an unstable API in the code, but not
`--unstable` flag provided.
This situation hinders DX and makes it harder to configure Deno. Failing
during runtime unless `--unstable` flag is provided is enough in this case.
This was incorrectly being stored so the AOT cache for JSR specifiers
wasn't being used. I added a wrapper type to help prevent the API being
used incorrectly.
This commit adds support for "rejectionhandled" Web Event and
"rejectionHandled" Node event.
```js
import process from "node:process";
process.on("rejectionHandled", (promise) => {
console.log("rejectionHandled", reason, promise);
});
window.addEventListener("rejectionhandled", (event) => {
console.log("rejectionhandled", event.reason, event.promise);
});

Ensures the Deno process is brought down even when the runtime gets hung
up on something.
Marvin found that the lsp was running without a parent vscode around so
this is maybe/probably related.
Fixes https://github.com/denoland/deno/issues/21840
The problem was hard to reproduce as its a race condition. I've added a
test that reproduces the problem 1/10 tries. We should move the
idleTimeout handling to Rust (maybe even built into fastwebsocket).
We were calling `expand_glob` on our excludes, which is very expensive
and unnecessary because we can pattern match while traversing instead.
1. Doesn't expand "exclude" globs. Instead pattern matches while walking
the directory.
2. Splits up the "include" into base paths and applicable file patterns.
This causes less pattern matching to occur because we're only pattern
matching on patterns that might match and not ones in completely
unrelated directories.
This defines the removal version of v2 for the following APIs that
favour the Streams API:
* `Deno.copy()`
* `Deno.File`
* `Deno.iter()`
* `Deno.Buffer`
* `Deno.readAll()`
* `Deno.readAllSync()`
* `Deno.writeAll()`
* `Deno.writeAllSync()`
* `Deno.FsWatcher.return()`
Part 1 of a potential 3 part series. Ref #13449
The current implementation passes key material back and forth RustCrypto
group of crates and ring. ring does not implement p521 yet.
This PR adds support for P521 named curve in `generateKey` and
`importKey` where we use RustCrypto. Other parts should be moved over to
the RustGroup group of crates for consistency.
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)
Fixes #20516
Follow up to #21747 and #21746
This tackles the last point of #20516 where certain inputs weren't
accepted in the other zlib methods
This adds the `toU8` conversion of `_brotli` to `_zlib.mjs`, when we
create the ZLibBuffer, we'll sanitize the input. I noticed that the
async had no handler for `string` input so I added that as well.
Fixes https://github.com/denoland/deno/issues/21734
Changes:
- Use default encode when options do not provide a encode callback.
- Remove internal TS for `node:querystring`. Its not helping catching
bugs like this because of invalid type assumptions and use of `any`,
more of a maintenance burden.
This fixes point 3 of https://github.com/denoland/deno/issues/20516
This PR creates consistency between the sync and async versions of the
brotli compress where we will always return a buffer like Node.
This fixes point 2 of #20516
This adds a conversion from Dataview/Buffer by returning `obj.buffer`
which can be converted to a `UInt8Array`.
Question: Regarding point 4 of the mentioned issue would it be
appropriate to copy the toU8 helper to the `zlib.mjs` methods?
These tests started failing on CI on Dec 28th, 2023 returning
ENOTFOUND. It's unclear what's going on, since `dig -x
8.8.8.8.in-addr.arpa`.
It needs a deeper investigation, but I want to unblock main branch
in the meantime.
Main change is that:
- "hyper" has been renamed to "hyper_v014" to signal that it's legacy
- "hyper1" has been renamed to "hyper" and should be the default
`opAsync` requires a lookup by name on each async call. This is a
mechanical translation of all opAsync calls to ensureFastOps.
The `opAsync` API on Deno.core will be removed at a later time.
When we migrate to op-import-per-extension, we will want to ensure that
ops have one and only one place where they are imported. This tackles
the ops that are imported via `ensureFastOps`, but does not yet tackle
direct `ops` imports.
Landing ahead of https://github.com/denoland/deno_core/pull/393
Node HTTP/2 was using the default h2 `Bytes` datatype when we can be
making using of `BufView` like we do in `Deno.serve`.
`fetch` and `Deno.serverHttp` can't make use of `BufView` because they
are using `reqwest` which is stuck on hyper 0.x at this time.
This commit adds a way to connect to the TS compiler host that is run
as part of the "deno lsp" subcommand. This can be done by specifying
"DENO_LSP_INSPECTOR" variable.
