2023-01-27chore: upgrade to Rust 1.67 (#17548)David Sherret

2023-01-14chore: use rustfmt imports_granularity option (#17421)Divy Srivastava
Closes https://github.com/denoland/deno/issues/2699 Closes https://github.com/denoland/deno/issues/2347 Uses unstable rustfmt features. Since dprint invokes `rustfmt` we do not need to switch the cargo toolchain to nightly. Do we care about formatting stability of our codebase across Rust versions? (I don't)

2022-12-15Revert "feat(ops): Fast zero copy string arguments (#16777)" (#17063)Bartek Iwańczuk
This reverts commit 9b2b8df927ac23cfa99016a684179f2a3198ba2e. Closes https://github.com/dsherret/ts-morph/issues/1372 Closes https://github.com/denoland/deno/issues/16979
2022-12-05fix(ops): disallow auto-borrowing OpState across potential await point (#16952)Divy Srivastava
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) ```
2022-12-02feat(ops): Fast zero copy string arguments (#16777)Divy Srivastava
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 } ```
2022-11-27feat(ops): fast calls for Wasm (#16776)Divy Srivastava
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]>, ) { // ... } ```
2022-11-27perf(ops): Reenable fast unit result optimization (#16827)Divy Srivastava
The optimization was missed in the optimizer rewrite https://github.com/denoland/deno/pull/16514
2022-11-26feat(ops): support raw pointer arguments (#16826)Divy Srivastava
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 { // .. } ```
2022-11-11feat(ops): implement fast lazy async ops (#16579)Divy Srivastava
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.
