Fixes #21660
Adds a basic `Immediate` class to mirror `NodeJS.Immediate`, and changes
`setImmediate` and `clearImmediate` to return and accept (respectively)
`Immediate` objects.
Note that for now {ref,unref,hasRef} are effectively stubs, as deno_core
doesn't really natively support immediates (they're currently modeled as
timers with delay of 0). Eventually we probably want to actually
implement these properly.
This commit changes how we figure out if we're running on main
thread in `node:worker_threads` module. Instead of relying on quirky
"magic variable" for a name to check if we're on main thread, we are
now explicitly passing this information during bootstrapping of the
runtime. As a side effect, `WorkerOptions.name` is more useful
and matches what Node.js does more closely (though not fully).

Unable to reproduce with a unit test, but assuming that it's a name
collision or create pipe/open pipe race, and adding some additional
diagnostics.
Gets us closer to solving #20707.
Rewrites the `TestEventSender`:
- Allow for explicit creation of multiple streams. This will allow for
one-std{out,err}-per-worker
- All test events are received along with a worker ID, allowing for
eventual, proper parallel threading of test events.
In theory this should open up proper interleaving of test output,
however that is left for a future PR.
I had some plans for a better performing synchronization primitive, but
the inter-thread communication is tricky. This does, however, speed up
the processing of large numbers of tests 15-25% (possibly even more on
100,000+).
Before
```
ok | 1000 passed | 0 failed (32ms)
ok | 10000 passed | 0 failed (276ms)
```
After
```
ok | 1000 passed | 0 failed (25ms)
ok | 10000 passed | 0 failed (230ms)
```
When using a prefix or suffix containing an invalid filename character,
it's not entirely clear where the errors come from. We make these errors
more consistent across platforms.
In addition, all permission prompts for tempfile and tempdir were
printing the same API name.
We also take the opportunity to make the tempfile random space larger by
2x (using a base32-encoded u64 rather than a hex-encoded u32).
This change deprecates
`Deno.CreateHttpClientOptions.{certChain,privateKey}` in favour of
`Deno.CreateHttpClientOptions.{cert,key}`.

Splitting the sleep and interval ops allows us to detect an interval
timer. We also remove the use of the `op_async_void_deferred` call.
A future PR will be able to split the op sanitizer messages for timers
and intervals.

of `TransformStream` `cancel()` method, so here go `CompressionStream`

Note: tests are not the only part of the codebase that uses `std`. Other
parts, like `tools/`, do too. So, it could be argued that this is a
little misleading. Either way, I'm doing this as discussed with
@mmastrac.
This PR separates integration tests from CLI tests into a new project
named `cli_tests`. This is a prerequisite for an integration test runner
that can work with either the CLI binary in the current project, or one
that is built ahead of time.
## Background
Rust does not have the concept of artifact dependencies yet
(https://github.com/rust-lang/cargo/issues/9096). Because of this, the
only way we can ensure a binary is built before running associated tests
is by hanging tests off the crate with the binary itself.
Unfortunately this means that to run those tests, you _must_ build the
binary and in the case of the deno executable that might be a 10 minute
wait in release mode.
## Implementation
To allow for tests to run with and without the requirement that the
binary is up-to-date, we split the integration tests into a project of
their own. As these tests would not require the binary to build itself
before being run as-is, we add a stub integration `[[test]]` target in
the `cli` project that invokes these tests using `cargo test`.
The stub test runner we add has `harness = false` so that we can get
access to a `main` function. This `main` function's sole job is to
`execvp` the command `cargo test -p deno_cli`, effectively "calling"
another cargo target.
This ensures that the deno executable is always correctly rebuilt before
running the stub test runner from `cli`, and gets us closer to be able
to run the entire integration test suite on arbitrary deno executables
(and therefore split the build into multiple phases).
The new `cli_tests` project lives within `cli` to avoid a large PR. In
later PRs, the test data will be split from the `cli` project. As there
are a few thousand files, it'll be better to do this as a completely
separate PR to avoid noise.
This moves the op sanitizer descriptions into Rust code and prepares for
eventual op import from `ext:core/ops`. We cannot import these ops from
`ext:core/ops` as the testing infrastructure ops are not always present.
Changes:
- Op descriptions live in `cli` code and are currently accessible via an
op for the older sanitizer code
- `phf` dep moved to workspace root so we can use it here
- `ops.op_XXX` changed to to `op_XXX` to prepare for op imports later
on.
Migrations:
- Error registration no longer required for Interrupted or BadResource
(these are core exception)
- `include_js_files!`/`ExtensionFileSource` changes
This commit adds `ppid` getter for `node:process` to improve Node
compatibility one step further.
There is one problem though, which is that `Deno.ppid`, which
`process.ppid` internally calls, is actually of type `bigint` although
it's supposed to be `number`. I filed an issue for this (#22166). For
the time being, explciit type conversion from `bigint` to `number` is
applied to match the Node.js behavior.
Fixes https://github.com/denoland/deno/issues/22180
Matches the Node.js implementation more closely. Removed types, they do
not help just make it harder to debug with stack traces.
Follow up to #22157.
This leaves us with 4 usages of `ensureFastOps()` in `deno` itself.
There's also about 150 usages of `Deno.core.ops.<op_name>` left as well.
For removal in Deno v2. There are two issues:
1. Any script being run causes the output of `warnOnDeprecatedApi()` to
be printed, even when none of the `rid` properties are called.
2. `.rid` of these classes is used in multiple tests. I'm not sure how
to account for that. I thought of having `STDIN_RID`, and friends,
constants, whose values can be shared between the tests and the classes
themselves. Should we go with that or do something else?

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.
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.

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.

Changes:
- Remove `.present()` and add a `presentGPUCanvasContext` (not exposed
yet to users)
- Move lazy load logic to `00_init.js`. This can be used to use webgpu
on-demand from future code (OffScreenCanvas)

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

Question: Regarding point 4 of the mentioned issue would it be
appropriate to copy the toU8 helper to the `zlib.mjs` methods?
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.

This is somewhat awkward because `V8CrossThreadTaskSpawner` requires

value out of a struct.

This PR is an attempt to fix
https://github.com/denoland/deno/issues/20293, in which node modules
connecting to databases fail due to TLS errors. I ran into this
attempting to use
[node-postgres](https://github.com/brianc/node-postgres) to connect to a
[Neon](https://neon.tech) database.
Investigating via `--inspect-brk` led me to notice that the hostname
eventually passed to `Deno.startTls` was null. The hostname is
determined by the following code:
f6b889b432/ext/node/polyfills/_tls_wrap.ts (L87-L89)
This logic doesn't appear to be correct. I couldn't find reference to
`servername` existing on the `secureContext` in either Node's or Deno's
docs. There's a lot of scope here, and it's my first time reading
through this code, so I could be missing something!
Node uses [the following
logic](2e458d9736/lib/_tls_wrap.js (L1679-L1682)
) to determine the hostname for certificate validation:
```
const hostname = options.servername ||
options.host ||
(options.socket && options.socket._host) ||
'localhost';
```
This PR updates the `TLSSocket` polyfill to use behave similarly (though
I omitted the default to `localhost` at the end; I'm not sure if
including it is necessary or correct). With this change, `node-postgres`
connects to my TLS endpoint successfully (aside: Neon requires SNI,
which also works as expected).

I tried to update the tests in
https://github.com/denoland/deno/blob/main/cli/tests/unit_node/tls_test.ts
to exercise this change, but the test fails for me on `main` on Linux. I
investigated briefly and noticed that the test fixture
`cli/tests/testdata/tls/localhost.crt` doesn't appear to include the
`subjectAltName` specified in `domains.txt`. I believe the certificate
isn't matching `localhost`, but that's where I ended investigating.
This commit refactors how we access "core", "internals" and
"primordials" objects coming from `deno_core`, in our internal JavaScript code.
Instead of capturing them from "globalThis.__bootstrap" namespace, we
import them from recently added "ext:core/mod.js" file.
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 commit stabilizes "Deno.HttpServer.shutdown" API as well as
Unix socket support in "Deno.serve" API.

This commit adds a method of `Symbol.dispose` to the object returned
from `Deno.createHttpClient`, so we can make use of [explicit resource
management](https://github.com/tc39/proposal-explicit-resource-management)
by declaring it with `using`.
This commit adds support for a new `kv.watch()` method that allows
watching for changes to a key-value pair. This is useful for cases
where you want to be notified when a key-value pair changes, but
don't want to have to poll for changes.

Switch `ext/fetch` over to `resourceForReadableStream` to simplify and
unify implementation with `ext/serve`. This allows us to work in Rust
with resources only.
Two additional changes made to `resourceForReadableStream` were
required:
- Add an optional length to `resourceForReadableStream` which translates
to `size_hint`
- Fix a bug where writing to a closed stream that was full would panic
Rust 1.74 may have made this code temporarily valid in [#113126 Replace
old private-in-public diagnostic with type privacy
lints](https://github.com/rust-lang/rust/pull/113126), so we didn't
catch it at build time.
It fails in 1.73 and +nightly, however.
Follow-up to #20822. cc @lrowe
The `httpServerExplicitResourceManagement` tests were randomly failing
on CI because of a race.
The `drain` waker was missing wakeup events if the listeners shut down
after the last HTTP response finished. If we lost the race (rare), the
server Rc would be dropped and we wouldn't poll it again.
This replaces the drain waker system with a signalling Rc that always
resolves when the refcount is about to become 1.
Fix verified by running serve tests in a loop:
```
for i in {0..100}; do cargo run --features=__http_tracing -- test
-A --unstable '/Users/matt/Documents/github/deno/deno/cli/tests/unit/ser
ve_test.ts' --filter httpServerExplicitResourceManagement; done;
```
This PR changes the `Deno.cron` API:
* Marks the existing function as deprecated
* Introduces 2 new overloads, where the handler arg is always last:
```ts
Deno.cron(
name: string,
schedule: string,
handler: () => Promise<void> | void,
)
Deno.cron(
name: string,
schedule: string,
options?: { backoffSchedule?: number[]; signal?: AbortSignal },
handler: () => Promise<void> | void,
)
```
This PR also fixes a bug, when other crons continue execution after one
of the crons was closed using `signal`.
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.
Use HttpRecord as response body so requests can be tracked all the way
to response body completion.
This allows Request properties to be accessed while the response body is
streaming.
Graceful shutdown now awaits a future instead of async spinning waiting
for requests to finish.
On the minimal benchmark this refactor improves performance an
additional 2% over pooling alone for a net 3% increase over the previous
deno main branch.
Builds upon https://github.com/denoland/deno/pull/20809 and
https://github.com/denoland/deno/pull/20770.

Reuse existing existing allocations for HttpRecord and response
HeaderMap where possible.
At request end used allocations are returned to the pool and the pool
and the pool sized to 1/8th the current number of inflight requests.
For http1 hyper will reuse the response HeaderMap for the following
request on the connection.

Makes the JavaScript Request use a v8:External opaque pointer to
directly refer to the Rust HttpRecord.
The HttpRecord is now reference counted. To avoid leaks the strong count
is checked at request completion.
Performance seems unchanged on the minimal benchmark. 118614 req/s this
branch vs 118564 req/s on main, but variance between runs on my laptop
is pretty high.

This PR uses the new `cancel` method of `TransformStream` to properly
clean up the internal `TextDecoder` used in `TextDecoderStream` if the
stream is cancelled.

We only want one zlib dependency.
Zlib dependencies are reorganized so they use a hidden
`__vendored_zlib_ng` flag in cli that enables zlib-ng for both libz-sys
(used by ext/node) and flate2 (used by deno_web).
This is the release commit being forwarded back to main for 1.38.1

We can move all promise ID knowledge to deno_core, allowing us to better
experiment with promise implementation in deno_core.
`{un,}refOpPromise(promise)` is equivalent to
`{un,}refOp(promise[promiseIdSymbol])`
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:

This PR adds unstable `Deno.cron` API to trigger execution of cron jobs.
* State: All cron state is in memory. Cron jobs are scheduled according
to the cron schedule expression and the current time. No state is
persisted to disk.
* Time zone: Cron expressions specify time in UTC.
* Overlapping executions: not permitted. If the next scheduled execution
time occurs while the same cron job is still executing, the scheduled
execution is skipped.
* Retries: failed jobs are automatically retried until they succeed or
until retry threshold is reached. Retry policy can be optionally
specified using `options.backoffSchedule`.
