1. Breaks up functionality within `ProcState` into several other structs
to break out the responsibilities (`ProcState` is only a data struct
now).
2. Moves towards being able to inject dependencies more easily and have
functionality only require what it needs.
3. Exposes `Arc<T>` around the "service structs" instead of it being
embedded within them. The idea behind embedding them was to reduce the
verbosity of needing to pass around `Arc<...>`, but I don't think it was
exactly working and as we move more of these structs to be more
injectable I don't think the extra verbosity will be a big deal.
Fixes https://github.com/denoland/deno/issues/18700
Timeline of the events that lead to the bug.
1. WebSocket handshake complete
2. Server on `read_frame` holding an AsyncRefCell borrow of the
WebSocket stream.
3. Client sends a TXT frame after a some time
4. Server recieves the frame and goes back to `read_frame`.
5. After some time, Server starts a `write_frame` but `read_frame` is
still holding a borrow!
^--- Locked. read_frame needs to complete so we can resume the write.
This commit changes all writes to directly borrow the
`fastwebsocket::WebSocket` resource under the assumption that it won't
affect ongoing reads.
Currently we are "waking up" the runtime if at the end of the event loop
tick there are ops that haven't been polled. Waking up incurs a syscall
and it appears we can do another tick of the event loop, without
going through the "wake up" machinery.
This commit refactors "deno_core" to do fewer boundary crossings
from Rust to V8. In other words we are now calling V8 from Rust fewer
times.
This is done by merging 3 distinct callbacks into a single one. Instead
of having "op resolve" callback, "next tick" callback and "macrotask
queue" callback, we now have only "Deno.core.eventLoopTick" callback,
which is responsible for doing the same actions previous 3 callbacks.
On each of the event loop we were doing at least 2 boundary crosses
(timers macrotask queue callback and unhandled promise rejection
callback) and up to 4 crosses if there were op response and next tick
callbacks coming from Node.js compatibility layer. Now this is all done
in a single callback.
Closes https://github.com/denoland/deno/issues/18620
Removes the functions in the `emit` module and replaces them with an
`Emitter` struct that can have "ctor dependencies" injected rather than
using functions to pass along the dependencies.
This is part of a long term refactor to move more functionality out of
proc state.
Stores the test/bench functions in rust op state during registration.
The functions are wrapped in JS first so that they return a directly
convertible `TestResult`/`BenchResult`. Test steps are still mostly
handled in JS since they are pretty much invoked by the user. Allows
removing a bunch of infrastructure for communicating between JS and
rust. Allows using rust utilities for things like shuffling tests
(`Vec::shuffle`). We can progressively move op and resource sanitization
to rust as well.
Fixes #17122.
Fixes #17312.
To make it easier to debug which tests are slowing us down.
Tests taking more than 5s have duration printed in red,
taking more than 1s in yellow and less than 1s are printed
without color.
This commit changes "eager ops" to directly return a response value
instead of calling "opresponse" callback in JavaScript. This saves
one boundary crossing and has a fantastic impact on the "async_ops.js"
benchmark:

Prerequisite for https://github.com/denoland/deno/pull/18652
The CLI docs suggested that all deno subcommands no longer type-check by
default. This is only the case for some subcommands, and this PR
clarifies the CLI docs in this regard.
- bump deps: the newest `lazy-regex` need newer `oncecell` and
`regex`
- reduce `unwrap`
- remove dep `lazy_static`
- make more regex cached

`current_dir().unwrap()` joined with a Path is equivalent to the
implementation in `resolve_from_cwd()`. Manually tested on Ubuntu 22.04
and Windows 11.

This should produce a little less garbage and using an object here
wasn't really required.

This commit abstracts out the specifics of the underlying system calls
FS operations behind a new `FileSystem` and `File` trait in the
`ext/fs` extension.
This allows other embedders to re-use ext/fs, but substituting in a
different FS backend.
This is likely not the final form of these traits. Eventually they will
be entirely `deno_core::Resource` agnostic, and will live in a seperate
crate.

Fixes #6259.
Adds the location for v8 syntax errors to the message (`message += " at
{location}"`) when rethrowing them for dynamic imports.
Discussing with @bartlomieju on discord I proposed just preserving v8's
error and not reconstructing it, allowing the standard stack trace to
just point to the syntax error instead of the dynamic import. But on
further thought this way has parity with SWC's syntax errors + has the
advantage of showing both the syntax error and dynamic import location.
```ts
// temp.js
await import("./temp2.js");
// temp2.js
function foo() {
await Promise.resolve();
}
// Before:
// error: Uncaught (in promise) SyntaxError: Unexpected reserved word
// await import("./temp2.js");
// ^
// at async file:///.../temp.js:1:1
// After:
// error: Uncaught (in promise) SyntaxError: Unexpected reserved word at file:///.../temp2.js:2:3
// await import("./temp2.js");
// ^
// at async file:///.../temp.js:1:1
```
This reloads an npm package's dependency's information when a
version/version req/tag is not found.
This PR applies only to dependencies of npm packages. It does NOT yet
cause npm specifiers to have their dependency information cache busted.
That requires a different solution, but this should help cache bust in
more scenarios.
Part of #16901, but doesn't close it yet
