## Why
Due to the usage of `&'alloc mut T` in `oxc_allocator::Box`, and
`bumpalo::collections::Vec` in `oxc_allocator::Vec`, ast types are
currently invariant over their allocator lifetime `'a`. This prevents
`ouroboros` from generating `borrow_*` on ast type fields, leading to
the unfriendly `with_*` api:
c250b288ef/crates/oxc_parser/examples/multi-thread.rs (L82-L84)
## How
- For `oxc_allocator::Vec`, switch to `allocator_api2::vec::Vec`, which
has a covariant relationship with the allocator lifetime.
- For `oxc_allocator::Box`, use `std::ptr::NonNull` which is
specifically designed to be covariant. I don't use
`allocator_api2::boxed::Box` because it holds the allocator for
dropping, so the size is bigger.
## Downside
Now that `oxc_allocator::Box` uses the unsafe `NonNull`. It has to be a
private field to be safe. This make it impossible to do `Box(....)`
pattern matching.
The sourcemap implement port from
[rust-sourcemap](https://github.com/getsentry/rust-sourcemap), but has
some different with it.
- Encode sourcemap at parallel, including quote `sourceContent` and
encode token to `vlq` mappings.
- Avoid `Sourcemap` some methods overhead, like `SourceMap::tokens()`
caused extra overhead at common cases. Here using `SourceViewToken` to
instead of it.
Unlike on other OS, on Windows there is no wildcard expansion/globbing
by the shell. Instead the application has to handle this. Therefore I
used the `glob` package to handle wildcards on Windows.
I also had to make the parent directory check more strict due to the
glob package resolving `..` in the middle of the path as well.
This closes#2695.
Export `SourcemapVisualizer` from codegen, it will be used oxc and
rolldown sourcemap test, so it support multiply source print, it will
using sourcemap `sourcesContent` as original source.
Add NodeJS parser to benchmarks.
Previous attempt #2724 did not work due CodSpeed producing very
inaccurate results (https://github.com/CodSpeedHQ/action/issues/96).
This version runs the actual benchmarks without CodSpeed's
instrumentation. Then another faux-benchmark runs within Codspeed's
instrumented action and just performs meaningless calculations in a loop
for as long as is required to take same amount of time as the original
uninstrumented benchmarks took.
It's unfortunate that we therefore don't get flame graphs on CodSpeed,
but this seems to be the best we can do for now.
This PR merges the previous confusing features `serde` and `wasm` into a
single `serialize` feature.
We'll eventually do serialize + type information for both wasm and napi
targets.
`oxc_macros` is removed from `oxc_ast`'s dependency because it requires
`syn` and friends, which goes against our policy ["Third-party
dependencies should be
minimal."](https://oxc-project.github.io/docs/contribute/rules.html#development-policy)
Closes#2641.
Also added `tsify` attribute to the `SerAttrs` derive macro, so `#[cfg_attr(feature = "wasm", tsify(...))]` can also be reduced to `#[tsify(...)]`.
I should've done a better job at selecting features. Every feature
requires more than just code to get it right.
linting by codeowners' files sounds good on paper but actually not that
useful.
