This is a prerequisite for fast streams work -- this particular resource
used a custom `mpsc`-style stream, and this work will allow us to unify
it with the streams in `ext/http` in time.
Instead of using Option as an internal semaphore for "correctly
completed EOF", we allow code to propagate errors into the channel which
can be picked up by downstream sinks like Hyper. EOF is signalled using
a more standard sender drop.
This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.
These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.
Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.
Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.
Closes #18804.

This commit provides basic polyfill for "node:test" module. Currently
only top-level "test" function is polyfilled, all remaining functions from
that module throw not implemented errors.
This addresses issue #19918.
## Issue description
Event messages have the wrong isTrusted value when they are not
triggered by user interaction, which differs from the browser. In
particular, all MessageEvents created by Deno have isTrusted set to
false, even though it should be true.
This is my first ever contribution to Deno, so I might be missing
something.
Includes a lightly-modified version of hyper-util's `TokioIo` utility.

Breaking Changes
Any IO transport type provided must not implement hyper::rt::{Read,
Write} instead of tokio::io traits. You can grab a helper type from
hyper-util to wrap Tokio types, or implement the traits yourself, if
it's a custom type.
([f9f65b7a](f9f65b7aa6))
client::conn::http2 types now use another generic for an Executor. Code
that names Connection needs to include the additional generic parameter.
([d977f209](d977f209bc))
The Service::call function no longer takes a mutable reference to self.
The FnMut trait bound on the service::util::service_fn function and the
trait bound on the impl for the ServiceFn struct were changed from FnMut
to Fn.
This PR fixes #19818. The problem was that the new InnerRequest class does not initialize the fields urlList and urlListProcessed that are used during a request clone. The solution aims to be straightforward by simply initializing the missing properties during the clone process. I also implemented a "cache" to the url getter of the new InnerRequest, avoiding the cost of calling op_http_get_request_method_and_url.
V8 doesn't like having internal slots on the "real" globalThis object.
This commit works around this limitation by storing the inner globalThis
objects for segregated globals in a context slot.
Benchmarking shows numbers are pretty close, however this is recommended
for the best possible thread-local performance and may improve in future
Rust compiler revisions.
Code run within Deno-mode and Node-mode should have access to a
slightly different set of globals. Previously this was done through a
compile time code-transform for Node-mode, but this is not ideal and has
many edge cases, for example Node's globalThis having a different
identity than Deno's globalThis.
This commit makes the `globalThis` of the entire runtime a semi-proxy.
This proxy returns a different set of globals depending on the caller's
mode. This is not a full proxy, because it is shadowed by "real"
properties on globalThis. This is done to avoid the overhead of a full
proxy for all globalThis operations.
The globals between Deno-mode and Node-mode are now properly segregated.
This means that code running in Deno-mode will not have access to Node's
globals, and vice versa. Deleting a managed global in Deno-mode will
NOT delete the corresponding global in Node-mode, and vice versa.

Fixes #19737 by adding brotli compression parameters.
Time after:
`Accept-Encoding: gzip`:
```
real 0m0.214s
user 0m0.005s
sys 0m0.013s
```
`Accept-Encoding: br`:
Before:
```
real 0m10.303s
user 0m0.005s
sys 0m0.010s
```
After:
```
real 0m0.127s
user 0m0.006s
sys 0m0.014s
```
This makes the implementation of "AsyncLocalStorage" from
"node:async_hooks" 3.5x faster than before for noop benchmark
(measuring baseline overhead). It's still 3.5x slower than not
using `AsyncLocalStorage` and 1.64x slower than using
noop promise hooks.
This commit stabilizes "Deno.serve()", which becomes the
preferred way to create HTTP servers in Deno.
Documentation was adjusted for each overload of "Deno.serve()"
API and the API always binds to "127.0.0.1:8000" by default.
This PR changes Web IDL interfaces to be declared with `var` instead of
`class`, so that accessing them via `globalThis` does not raise type
errors.
Closes #13390.
Fixes #19687 by adding a rejection handler to the write inside the
setTimeout. There is a small window where the promise is actually not
awaited and may reject without a handler.
Implementation of generics for `#[op2]`, along with some refactoring to
improve the ergonomics of ops with generics parameters:
- The ops have generics on the struct rather than the associated
methods, which allows us to trait-ify ops (impossible when they are on
the methods)
- The decl() method can become a trait-associated const field which
unlocks future optimizations
Callers of ops need to switch from:
`op_net_connect_tcp::call::<TestPermission>(conn_state, ip_addr)` to
`op_net_connect_tcp::<TestPermission>::call(conn_state, ip_addr)`.
Fixes the WPT tests that test w/invalid codes. Also explicitly ignoring
some h2 tests to hopefully prevent flakes.
The previous changes to WebSocketStream introduced a bug where the close
errors were not made available if the `pull` method was re-entrant.
This is a fix for issue #19644, concerning the `parseCssColor` function
in the file `ext/console/01_console.js`. Changes made on lines
2756-2758. To sum it up:
> The internal `parseCssColor` function currently parses 3/4-digit hex
colors incorrectly. For example, it parses the string `#FFFFFF` as
`[255, 255, 255]` (as expected), but returns `[240, 240, 240]` for
`#FFF`, when it should return the same triplet as the former.
While it's not going to cause a fatal runtime error, it did bug me
enough to fix it real quick.

Relands #19463. This time the `ExtensionFileSourceCode` enum is
preserved, so this effectively just splits feature
`include_js_for_snapshotting` into `exclude_js_sources` and
`runtime_js_sources`, adds a `force_include_js_sources` option on
`extension!()`, and unifies `ext::Init_ops_and_esm()` and
`ext::init_ops()` into `ext::init()`.
This is a new op system that will eventually replace `#[op]`.
Features
- More maintainable, generally less-coupled code
- More modern Rust proc-macro libraries
- Enforces correct `fast` labelling for fast ops, allowing for visual
scanning of fast ops
- Explicit marking of `#[string]`, `#[serde]` and `#[smi]` parameters.
This first version of op2 supports integer and Option<integer>
parameters only, and allows us to start working on converting ops and
adding features.
The WHATWG DOM specification has corrected the spelling of "slotable" to
"slottable".[1] This commit aligns our implementation accordingly.

Fixes #19568
Values are not coerced to the desired type during deserialisation. This
makes serde_v8 stricter.

`ZeroCopyBuf` was convenient to use, but sometimes it did hide details
that some copies were necessary in certain cases. Also it made it way to easy
for the caller to pass around and convert into different values. This commit
splits `ZeroCopyBuf` into `JsBuffer` (an array buffer coming from V8) and
`ToJsBuffer` (a Rust buffer that will be converted into a V8 array buffer).
As a result some magical conversions were removed (they were never used)
limiting the API surface and preparing for changes in #19534.
Fixes a bug I noticed when deriving a key based from `ECDH`. Similar
issue is also mentioned in #14693, where they derive a key using
`PBKDF2`
- In the WebCrypto API, `deriveKey()` is equivalent to `deriveBits()`
followed by `importKey()`
- But, `deriveKey()` requires just `deriveKey` in the `usages` of the
`baseKey` parameter. The `deriveBits` usage is not required to be
allowed. This is the uniform behaviour in Node, Chrome and Firefox.
- The impl currently has userland-accessible `SubtleCrypto.deriveKey()`
and `SubtleCrypto.deriveBits()`, as well as an internal `deriveBits()`
(this is the one that accesses the ffi).
- Also, `SubtleCrypto.deriveKey()` checks if `deriveKey` is an allowed
usage and `SubtleCrypto.deriveBits()` checks if `deriveBits` is an
allowed usage, as required.
- However, the impl currently calls the userland accessible
`SubtleCrypto.deriveBits()` in `SubtleCrypto.deriveKey()`, leading to an
error being thrown if the `deriveBits` usage isn't present.
- Fixed this by making it call the internal `deriveBits()`
instead.
