(#17003)
This commit stabilizes following APIs:
- `Deno.TcpConn.setNoDelay()`
- `Deno.TcpConn.setKeepAlive()`
|
|
Fixes https://github.com/denoland/deno/issues/16934
Example compiler error:
```
error: mutable opstate is not supported in async ops
--> core/ops_builtin.rs:122:1
|
122 | #[op]
| ^^^^^
|
= note: this error originates in the attribute macro `op` (in Nightly builds, run with -Z macro-backtrace for more info)
```

Uses SeqOneByteString optimization to do zero-copy `&str` arguments in
fast calls.
- [x] Depends on https://github.com/denoland/rusty_v8/pull/1129
- [x] Depends on
https://chromium-review.googlesource.com/c/v8/v8/+/4036884
- [x] Disable in async ops
- [x] Make it work with owned `String` with an extra alloc in fast path.
- [x] Support `Cow<'_, str>`. Owned for slow case, Borrowed for fast
case
```rust
#[op]
fn op_string_len(s: &str) -> u32 {
str.len() as u32
}
```

This PR introduces Wasm ops. These calls are optimized for entry from
Wasm land.
The `#[op(wasm)]` attribute is opt-in.
Last parameter `Option<&mut [u8]>` is the memory slice of the Wasm
module *when entered from a Fast API call*. Otherwise, the user is
expected to implement logic to obtain the memory if `None`
```rust
#[op(wasm)]
pub fn op_args_get(
offset: i32,
buffer_offset: i32,
memory: Option<&mut [u8]>,
) {
// ...
}
```
|
|
The optimization was missed in the optimizer rewrite
https://github.com/denoland/deno/pull/16514
|
|
Upgrade fast_call tests to full (both tier) codegen tests.

See https://github.com/denoland/deno/pull/16814#discussion_r1032744083.
Allows nullable buffers in low-level ops like FFI:
```rust
fn op_ffi_ptr_of<FP>(
state: &mut OpState,
buf: *const u8,
out: &mut [u32],
)
where
FP: FfiPermissions + 'static {
// ..
}
```

- [x] Avoid copying buffers.
https://encoding.spec.whatwg.org/#dom-textdecoder-decode
> Implementations are strongly encouraged to use an implementation
strategy that avoids this copy. When doing so they will have to make
sure that changes to input do not affect future calls to
[decode()](https://encoding.spec.whatwg.org/#dom-textdecoder-decode).
- [x] Special op to avoid string label deserialization and parsing.
(Ideally we should map labels to integers in JS)
- [x] Avoid webidl `Object.assign` when options is undefined.

Implements fast scheduling of deferred op futures.
```rs
#[op(fast)]
async fn op_read(
state: Rc<RefCell<OpState>>,
rid: ResourceId,
buf: &mut [u8],
) -> Result<u32, Error> {
// ...
}
```
The future is scheduled via a fast API call and polled by the event loop
after being woken up by its waker.

V8's JIT can do a better job knowing the argument count and also enable
fast call path (in future).
This also lets us call async ops without `opAsync`:
```js
const { ops } = Deno.core;
await ops.op_void_async();
```
this patch: 4405286 ops/sec
main: 3508771 ops/sec

This revert has been discussed at length out-of-band (including with
@andreubotella). The realms work in impeding ongoing event loop and
performance work. We very much want to land realms but it needs to wait
until these lower-level refactors are complete. We hope to bring realms
back in a couple weeks.

This PR makes pointer read methods of `Deno.UnsafePointerView` Fast API
compliant, with the exception of `getCString` which cannot be made fast
with current V8 Fast API.
