perf(size): use unstable sort where stability is unneeded by Boshen · Pull Request #9803 · rolldown/rolldown

Boshen · 2026-06-16T15:53:06Z

Flip stable slice sorts to unstable in rolldown's own crates where stability is not needed. std's stable sort monomorphizes to a larger driver than the unstable sort; at sites whose sort key is unique (or that sort full values), stable and unstable produce identical output, so this is a free code-size trim.

Sites flipped (12, output-identical)

Unique key ⇒ no ties ⇒ order is deterministic regardless of stability:

rolldown/src/chunk_graph.rs — by module id() (unique; neighbours were already sort_unstable)
rolldown/src/hmr/hmr_stage.rs — by stable_id() (unique; comment notes the sort is only for deterministic snapshots)
rolldown/.../generate_stage/compute_cross_chunk_links.rs & code_splitting.rs — by exec_order (unique)
rolldown/.../generate_stage/manual_code_splitting.rs — by stable_id().then(exec_order) (stable_id unique ⇒ no ties)
rolldown/src/types/scan_stage_cache.rs — by map key (unique)
rolldown_common/src/types/output_chunk.rs — by exec_order (unique)
rolldown_plugin_bundle_analyzer/src/render_markdown.rs (×2) — by unique module path

Full-value .sort() (equal elements are identical, so order is unobservable):

rolldown_error/.../events/tsconfig_error.rs — Vec<path>
rolldown_error/.../constructors.rs (×2) — Vec<String> importer lists

Left stable (ties possible / order matters)

tree_shaking/include_statements.rs (bailout entries tie on Reverse(MAX)), scan_stage.rs (sourcemap-chain plugin order), and the Reverse(len) / size / file_name / duration projection sorts.

Verification

All 1752 runnable integration/snapshot fixtures pass with no snapshot changes (the only failures in an isolated worktree are pre-existing environment issues — missing node_modules/test262 submodule — which fail identically on the unchanged base). cargo clippy (with --features experimental, the shipped config) and cargo fmt clean.

Binary size impact: −16,544 bytes (−16.15 KiB) on the release librolldown_binding.dylib (fat-LTO, codegen-units=1, strip="symbols"): base 23,459,424 → branch 23,442,880.

Flip stable slice sorts to **unstable** in rolldown's own crates where stability is not needed. `std`'s stable sort monomorphizes to a larger driver than the unstable sort; at sites whose sort key is unique (or that sort full values), stable and unstable produce **identical** output, so this is a free code-size trim. ## Sites flipped (12, output-identical) Unique key ⇒ no ties ⇒ order is deterministic regardless of stability: - `rolldown/src/chunk_graph.rs` — by module `id()` (unique; neighbours were already `sort_unstable`) - `rolldown/src/hmr/hmr_stage.rs` — by `stable_id()` (unique; comment notes the sort is only for deterministic snapshots) - `rolldown/.../generate_stage/compute_cross_chunk_links.rs` & `code_splitting.rs` — by `exec_order` (unique) - `rolldown/.../generate_stage/manual_code_splitting.rs` — by `stable_id().then(exec_order)` (`stable_id` unique ⇒ no ties) - `rolldown/src/types/scan_stage_cache.rs` — by map key (unique) - `rolldown_common/src/types/output_chunk.rs` — by `exec_order` (unique) - `rolldown_plugin_bundle_analyzer/src/render_markdown.rs` (×2) — by unique module path Full-value `.sort()` (equal elements are identical, so order is unobservable): - `rolldown_error/.../events/tsconfig_error.rs` — `Vec<path>` - `rolldown_error/.../constructors.rs` (×2) — `Vec<String>` importer lists ## Left stable (ties possible / order matters) `tree_shaking/include_statements.rs` (bailout entries tie on `Reverse(MAX)`), `scan_stage.rs` (sourcemap-chain plugin order), and the `Reverse(len)` / `size` / `file_name` / `duration` projection sorts. ## Verification All 1752 runnable integration/snapshot fixtures pass with **no snapshot changes** (the only failures in an isolated worktree are pre-existing environment issues — missing `node_modules`/`test262` submodule — which fail identically on the unchanged base). `cargo clippy` (with `--features experimental`, the shipped config) and `cargo fmt` clean. **Binary size impact:** **−16,544 bytes (−16.15 KiB)** on the release `librolldown_binding.dylib` (fat-LTO, `codegen-units=1`, `strip="symbols"`): base `23,459,424` → branch `23,442,880`.

#9755 already made the external default-import name deterministic via `min_by_key((stable_id, name))` plus an always-on stable sort. This refines that path without changing output: - `sort_by` -> `sort_unstable_by`, guarded by `len > 1`: stability is needless since the names are unique `FxHashMap` keys, and this matches the project direction in #9803 (use unstable sort where stability is unneeded). - default-name selection uses `exec_order()` (u32 compare) instead of `stable_id().as_str()` (string compare): cheaper, and consistent with the sibling `external_import_namespace_merger`, which `code_splitting.rs` already orders by `exec_order()`. All rolldown integration snapshot tests pass unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

## [1.1.2] - 2026-06-18 ### 📝 Notable tsconfig behavior changes These ship via the `oxc_resolver` 11.21.3 bump (#9841) and affect `resolve.tsconfigPaths` (Vite 8 resolves through oxc-resolver): - **Honor explicit non-TS extensions in `include`** (oxc-project/oxc-resolver#1213). `compilerOptions.paths` now resolve for importers whose extension is explicitly listed in a tsconfig's `include` (e.g. `src/**/*.vue`, `src/**/*.svelte`). Previously oxc-resolver filtered importers by extension before evaluating the `include` globs, so a `.vue`/`.svelte` file listed in `include` never matched its project and its `paths` were skipped. This unblocks the default create-vite Vue + TS layout (a solution-style root plus a referenced `tsconfig.app.json` that declares `paths` and `include: ["src/**/*.ts", "src/**/*.vue"]`). Matches vue-tsc and svelte-check, which register these extensions via TypeScript's `extraFileExtensions`. - **No fallback to the outermost tsconfig in auto-discovery** (oxc-project/oxc-resolver#1220). Auto-discovery no longer attaches the topmost ancestor `tsconfig.json` to a file that no project actually owns (via `files` / `include` / project references). Previously such a file inherited the outermost ancestor's `paths` / `baseUrl`, leaking aliases into files that project does not own. oxc-resolver now returns no config in that case, matching tsserver / typescript-go, which route such files to an inferred project with no aliases. ### 🚀 Features -
