Add cargo-miri support and fix HiveArray aliasing UB (
80a06a8)
Bun now has a bun run rust:miri workflow that runs cargo miri test over a curated set of pure-Rust crates, using Tree Borrows to better match the project’s aliasing patterns. The same change also fixes a serious HiveArray aliasing issue and updates a number of nearby collections/runtime paths to be Miri-safe.
Install now reuses existing folder/tarball entries (
035add3)
bun add -g no longer appends duplicate package.json entries when the same local folder/tarball-style dependency is installed again. This closes a real install-idempotency bug, including the aliasing case where the user explicitly wants a separate package name.
Fix utf16le fs.readFile layout UB (
655398c)
The UTF-16/ucs2 fs.readFile path no longer reinterprets a Vec<u8> as a Vec<u16> with mismatched allocator layout. It now copies into a properly aligned Vec<u16>, removing undefined behavior in a public file-reading code path.
Collapse dead bundler generic and gate cpuid correctly (c7a7579)
ThreadPool::init drops an obsolete generic left over from the Zig-to-Rust port, simplifying the API now that the duplicate BundleV2 path is gone. The hardware timer cpuid helpers are also gated out on macOS and FreeBSD x86_64, avoiding platform-specific misuse.
Bundler/transpiler hot paths were optimized (945b894)
This day includes a broad performance pass across bundling, parsing, printing, renaming, and sourcemap generation. It also adds a benchmark fixture, suggesting the changes were aimed at real hot-path wins rather than just cleanup.
Miscellaneous refactors and safety cleanup (172afa5, 
112f305)
- Replaced Bun-specific assert helpers with Rust
assert!macros across many files. - Removed unnecessary
unsafestring conversions for static literals.
