Classic worker scripts are now executed in the context of a Tokio
runtime. This does mean we can not spawn more tokio runtimes in
"op_worker_sync_fetch". We instead spawn a new thread there, that can
create a new Tokio runtime that we can use to block the worker thread.
This commit implements classic workers, but only when the `--enable-testing-features-do-not-use` flag is provided. This change is not user facing. Classic workers are used extensively in WPT tests. The classic workers do not support loading from disk, and do not support TypeScript.

* refactor(ops): return BadResource errors in ResourceTable calls
Instead of relying on callers to map Options to Results via `.ok_or_else(bad_resource_id)` at over 176 different call sites ...
This commit adds "--unsafely-treat-insecure-origin-as-secure" flag
that allows to disable SSL verification for all domains, or specific
domains if they were passed as an argument to the flag.

This commit adds "DENO_TLS_CA_STORE" env variable to support
optionally loading certificates from the users local certificate store.
This will allow them to successfully connect via tls with corporate
and self signed certs provided they have them installed in their keystore.
It also allows them to deal with revoked certs by simply updating
their keystore without having to upgrade Deno.
Currently supported values are "mozilla", "system" or empty value.
This commit removes implementation of "native plugins" and replaces
it with FFI API.
Effectively "Deno.openPlugin" API was replaced with "Deno.dlopen" API.
Oneshot is more appropriate because mod_evaluate() only sends a single
value.
It also makes it easier to use it correctly. As an embedder, I wasn't
sure if I'm expected to drain the channel or not.
This commit changes return type of JsRuntime::execute_script to include
v8::Value returned from evaluation.
When embedding deno_core it is sometimes useful to be able to inspect
script evaluation value without the hoops of adding ops to store the
value on the OpState.
v8::Global<v8::Value> is used so consumers don't have to pass
scope themselves.
The WebAssembly streaming APIs used to be enabled, but used to take
buffer sources as their first argument (see #6154 and #7259). This
change re-enables them, requiring a Promise<Response> instead, as well as
enabling asynchronous compilation of WebAssembly modules.
This commits moves implementation of net related APIs available on "Deno"
namespace to "deno_net" extension.
Following APIs were moved:
- Deno.listen()
- Deno.connect()
- Deno.listenTls()
- Deno.serveHttp()
- Deno.shutdown()
- Deno.resolveDns()
- Deno.listenDatagram()
- Deno.startTls()
- Deno.Conn
- Deno.Listener
- Deno.DatagramConn
This commit adds support for piping console messages to inspector.
This is done by "wrapping" Deno's console implementation with default
console provided by V8 by the means of "Deno.core.callConsole" binding.
Effectively each call to "console.*" methods calls a method on Deno's
console and V8's console.
This commit adds new options to unstable "Deno.createHttpClient" API.
"proxy" and "basicAuth" options were added that allow to use custom proxy
when client instance is passed to "fetch" API.
This commit renames "JsRuntime::execute" to "JsRuntime::execute_script". Additionally
same renames were applied to methods on "deno_runtime::Worker" and
"deno_runtime::WebWorker".
A new macro was added to "deno_core" called "located_script_name" which
returns the name of Rust file alongside line no and col no of that call site.
This macro is useful in combination with "JsRuntime::execute_script"
and allows to provide accurate place where "one-off" JavaScript scripts
are executed for internal runtime functions.

This commit changes "op_http_response_write" to first send response chunk
and then poll the underlying HTTP connection.
Previously after writing a chunk of response HTTP connection wasn't polled
and thus data wasn't written to the socket until after next op interacting
with the connection.
Waiting on next request in Deno.serveHttp() API hanged
when responses were using ReadableStream. This was caused
by op_http_request_next op that was never woken after
response was fully written. This commit adds waker field to
DenoService which is called after response is finished.
This commit removes all JS based text encoding / text decoding. Instead
encoding now happens in Rust via encoding_rs (already in tree). This
implementation retains stream support, but adds the last missing
encodings. We are incredibly close to 100% WPT on text encoding now.
This should reduce our baseline heap by quite a bit.
This commit adds "CancelHandle" to "ConnResource" and changes
"op_http_next_request" to await for the cancel signal. In turn
when async iterating over "Deno.HttpConn" the iterator breaks
upon closing of the resource.
This commit moves implementation of "JsRuntimeInspector" to "deno_core" crate.
To achieve that following changes were made:
* "Worker" and "WebWorker" no longer own instance of "JsRuntimeInspector",
instead it is now owned by "deno_core::JsRuntime".
* Consequently polling of inspector is no longer done in "Worker"/"WebWorker",
instead it's done in "deno_core::JsRuntime::poll_event_loop".
* "deno_core::JsRuntime::poll_event_loop" and "deno_core::JsRuntime::run_event_loop",
now accept "wait_for_inspector" boolean that tells if event loop should still be
"pending" if there are active inspector sessions - this change fixes the problem
that inspector disconnects from the frontend and process exits once the code has
stopped executing.
This commit refactors implementation of inspector.
The intention is to be able to move inspector implementation to "deno_core".
Following things were done to make that possible:
* "runtime/inspector.rs" was split into "runtime/inspector/mod.rs"
and "runtime/inspector/server.rs", separating inspector implementation
from Websocket server implementation.
* "DenoInspector" was renamed to "JsRuntimeInspector" and reference to "server"
was removed from the structure, making it independent of Websocket server
used to connect to Chrome Devtools.
* "WebsocketSession" was renamed to "InspectorSession" and rewritten in such
a way that it's not tied to Websockets anymore; instead it accepts a pair
of "proxy" channel ends that allow to integrate the session with different
"transports".
* "InspectorSession" was renamed to "LocalInspectorSession" to better indicate
that it's an "in-memory" session and doesn't require Websocket server. It was
also rewritten in such a way that it uses "InspectorSession" from previous point
instead of reimplementing "v8::inspector::ChannelImpl" trait; this is done by using
the "proxy" channels to communicate with the V8 session.
Consequently "LocalInspectorSession" is now a frontend to "InspectorSession". This
introduces a small inconvenience that awaiting responses for "LocalInspectorSession" requires
to concurrently poll worker's event loop. This arises from the fact that "InspectorSession"
is now owned by "JsRuntimeInspector", which in turn is owned by "Worker" or "WebWorker".
To ease this situation "Worker::with_event_loop" helper method was added, that takes
a future and concurrently polls it along with the event loop (using "tokio::select!" macro
inside a loop).
Replaces the file-backed provider by an in-memory one because proper
file locking is a hard problem that detracts from the proof of concept.
Teach the WPT runner how to extract tests from .html files because all
the relevant tests in test_util/wpt/webmessaging/broadcastchannel are
inside basics.html and interface.html.
In #9118, TLS streams were split into a "read half" and a "write half"
using tokio::io::split() to allow concurrent Conn#read() and
Conn#write() calls without one blocking the other. However, this
introduced a bug: outgoing data gets discarded when the TLS stream is
gracefully closed, because the read half is closed too early, before all
TLS control data has been received.

This ensures that provided extensions are all correctly setup and ready to use once the JsRuntime constructor returns
Note: this will also initialize ops for to-be-snapshotted runtimes
This commit adds support for running test in parallel.
Entire test runner functionality has been rewritten
from JavaScript to Rust and a set of ops was added to support reporting in Rust.
A new "--jobs" flag was added to "deno test" that allows to configure
how many threads will be used. When given no value it defaults to 2.
Extensions allow declarative extensions to "JsRuntime" (ops, state, JS or middleware).
This allows for:
- `op_crates` to be plug-and-play & self-contained, reducing complexity leaked to consumers
- op middleware (like metrics_op) to be opt-in and for new middleware (unstable, tracing,...)
- `MainWorker` and `WebWorker` to be composable, allowing users to extend workers with their ops whilst benefiting from the other infrastructure (inspector, etc...)
In short extensions improve deno's modularity, reducing complexity and leaky abstractions for embedders and the internal codebase.
`InvalidDNSNameError` is thrown when a string is not a valid hostname,
e.g. it contains invalid characters, or starts with a numeric digit. It
does not involve a (failed) DNS lookup.
This commits adds adds "permissions" option to the test definitions
which allows tests to run with different permission sets than
the process's permission.
The change will only be in effect within the test function, once the
test has completed the original process permission set is restored.
Test permissions cannot exceed the process's permission.
You can only narrow or drop permissions, failure to acquire a
permission results in an error being thrown and the test case will fail.
Even if bootstrapping the JS runtime is low level, it's an abstraction leak of
core to require users to call `Deno.core.ops()` in JS space.
So instead we're introducing a `JsRuntime::sync_ops_cache()` method,
once we have runtime extensions a new runtime will ensure the ops
cache is setup (for the provided extensions) and then loading/unloading
plugins should be the only operations that require op cache syncs
- register builtin v8 errors in core.js so consumers don't have to
- remove complexity of error args handling (consumers must provide a
constructor with custom args, core simply provides msg arg)
This commit aligns the `fetch` API and the `Request` / `Response`
classes belonging to it to the spec. This commit enables all the
relevant `fetch` WPT tests. Spec compliance is now at around 90%.
Performance is essentially identical now (within 1% of 1.9.0).
This commit fixes the URL returned from `request.url` in the HTTP server
to be fully qualified. This previously existed, but was removed and
accidentially not readded during optimizations of the HTTP ops.
Returning a non fully qualified URL from `Request#url` is not spec
compliant.
The panic was caused by the lack of an error class mapping for
futures::channel::TrySendError, but it shouldn't have been throwing an error in
the first place - when a worker has terminated, postMessage should just return.
The issue was that the termination message hadn't yet been recieved, so it was
carrying on with trying to send the message. This adds another check on the Rust
side for if the channel is closed, and if it is the worker is treated as
terminated.
This commit introduces a performance optimization for the native HTTP
server. From my testing it is about 2-6% faster than `main`. Request
headers in the HTTP servers are now lazilly instatated when they are
accessed, rather than being preemptively wrapped in the `Headers` class.
This stabilizes Deno.ftruncate and Deno.ftruncateSync.
This is a well known system call and the interface is
not going to change. Implicitly requires write permissions
as the file has to be opened with write to be truncated.
This commit adds allowlist support to `--allow-run` flag.
Additionally `Deno.permissions.query()` allows to query for specific
programs within allowlist.
This commit adds blob URL support. Blob URLs are stored in a process
global storage, that can be accessed from all workers, and the module
loader. Blob URLs can be created using `URL.createObjectURL` and revoked
using `URL.revokeObjectURL`.
This commit does not add support for `fetch`ing blob URLs. This will be
added in a follow up commit.
This commit marks the `Deno.Buffer` / `Deno.readAll` /
`Deno.readAllSync` / `Deno.writeAll` / `Deno.writeAllSync` utils as
deprecated, and schedules them for removal in Deno 2.0. These
utilities are implemented in pure JS, so should not be part of the
Deno namespace.
These utilities are now available in std/io/buffer and std/io/util:
https://github.com/denoland/deno_std/pull/808.
This additionallty removes all internal dependance on Deno.Buffer.
- Improves op performance.
- Handle op-metadata (errors, promise IDs) explicitly in the op-layer vs
per op-encoding (aka: out-of-payload).
- Remove shared queue & custom "asyncHandlers", all async values are
returned in batches via js_recv_cb.
- The op-layer should be thought of as simple function calls with little
indirection or translation besides the conceptually straightforward
serde_v8 bijections.
- Preserve concepts of json/bin/min as semantic groups of their
inputs/outputs instead of their op-encoding strategy, preserving these
groups will also facilitate partial transitions over to v8 Fast API for the
"min" and "bin" groups
This commit moves implementation of bin ops to "deno_core" crates
as well as unifying logic between bin ops and json ops to reuse
as much code as possible (both in Rust and JavaScript).
Change `Console.#printFunc` to pass a log level as the second argument
(0 = debug, 3 = error), instead of a boolean for `isErr`. This does not
change the Deno runtime behaviour at all.
This commit rewrites "dispatch_minimal" into "dispatch_buffer".
It's part of an effort to unify JS interface for ops for both json
and minimal (buffer) ops.
Before this commit "minimal ops" could be either sync or async
depending on the return type from the op, but this commit changes
it to have separate signatures for sync and async ops (just like
in case of json ops).
This commit starts splitting out the deno_web op crate into multiple
smaller crates. This commit splits out WebIDL and URL API, but in the
future I want to split out each spec into its own crate. That means we
will have (in rough order of loading): `webidl`, `dom`, `streams`,
`console`, `encoding`, `url`, `file`, `fetch`, `websocket`, and
`webgpu` crates.
This commit rewrites implementation of "JsRuntime::mod_evaluate".
Event loop is no longer polled automatically and users must manually
drive event loop forward after calling "mod_evaluate".

This commit makes "Deno.link" and "Deno.linkSync" stable.
The permission required has been changed to read-write to
ensure one cannot escape the sandbox.
This adds an exit sanitizer to ensure that code being tested or
dependencies of that code can't accidentally call "Deno.exit"
leading to partial test runs and false results.
Include the lower-level error message in the generic error message.
No test because I can't actually make it fail by passing it bad PEM.
I checked and `reqwest::Certificate::from_pem()` always returns `Ok()`.
Fixes #9364.
Previously, calling `Process#kill()` after the process had exited would
sometimes throw a `TypeError` on Windows. After this patch, it will
throw `NotFound` instead, just like other platforms.
This patch also fixes flakiness of the `runKillAfterStatus` test on
Windows.
