Description

Base of a 3-PR stack: #13641 (this) → #13642 (parallel fingerprint) → #13643 (parallel identity build). This PR targets main; review in order. Together they cut package-graph construction ~264 ms → ~178 ms (~33%) on the profiled repo.

Profiling package-graph construction on a large real-world pnpm monorepo (~1,200 workspaces) showed resolve_dependencies materializing every workspace's external closure independently: one ExternalPackageIdentity per closure member per workspace (two string clones plus a human_name lockfile lookup each — ~390k constructions total), then one fingerprint hash per workspace over the full (key, version) sequence. Only ~two-thirds of those closures are actually distinct — the rest is duplicated work.

Changes:

  • PackageResolution now stores its identity list as Arc<[ExternalPackageIdentity]>. The list is sorted/deduped at construction (new, the only constructor) and immutable afterward.
  • resolve_dependencies shares one materialized list across workspaces whose closures are identical, detected by the closure's Arc pointer sequence. Closure members are interned Arcs whenever the shared closure DP produced them (pnpm today; npm/yarn1 with perf: Enable shared closure DP for npm and yarn1 lockfiles #13635), so identical pointer sequences ⇔ identical closures. Legacy-walk formats produce distinct pointers per workspace and simply keep building independently — behavior unchanged, no penalty.
  • ExternalResolutionGeneration::build fingerprints each distinct list once, memoized by slice address — at most one map probe per package (not per member), so unshared lists pay nothing measurable beyond the hash they already required. Its per-package re-sort is dropped since new already guarantees the invariant.

Public surface is unchanged: identities() still returns &[ExternalPackageIdentity], new() has the same signature, and cargo/uv resolution producers are untouched. Cloning a resolution/generation is now a refcount bump instead of a deep identity-list copy.

Measured on the profiled repo (release, 8 warm samples per side): package graph construction ~264 ms → ~249 ms median (~6%) from this PR alone, with a ~35% cut in identity-list allocations. The two PRs stacked on top take it to ~178 ms.

For transparency: two cheaper alternatives were tried first — per-member identity memoization and content-keyed fingerprint dedup — and both measured neutral-to-worse (per-member map probes cost what they saved), which is why this lands as the structural pointer-keyed sharing instead.

Testing Instructions

  • cargo test -p turborepo-repository — all 419 tests pass (identity ordering/dedup through new, generation building, cross-domain validation).
  • cargo check -p turborepo-lib compiles unchanged against the new field representation.
  • cargo clippy -p turborepo-repository --all-targets is clean.
  • Fingerprint semantics are unchanged: the hash input is the same sorted, deduped (key, version) sequence as before; sharing only avoids recomputing it for byte-identical sequences.

perf: Share resolution identity lists across identical workspace clos…
ad88e89 
…ures

Building the external resolution generation materialized every
workspace's closure independently: one ExternalPackageIdentity per
closure member per workspace (two string clones plus a human_name
lockfile lookup each), then one fingerprint hash per workspace over the
full (key, version) sequence. On a large real-world monorepo that is
389k identity constructions across 1,226 workspaces — of which only 802
closures are actually distinct.

Store PackageResolution's identity list behind an Arc. The list is
sorted and deduped at construction and immutable afterward, so:

- resolve_dependencies shares one materialized list across workspaces
  whose closures are identical, detected by the closure's Arc pointer
  sequence (closure members are interned Arcs whenever the shared
  closure DP produced them; legacy-walk formats produce distinct
  pointers and keep building independently, unchanged).
- ExternalResolutionGeneration::build fingerprints each distinct list
  once, keyed by slice address — at most one map probe per package, so
  unshared lists pay nothing beyond the hash they already required.
- build's per-package re-sort is dropped: PackageResolution::new is the
  only constructor and already guarantees the invariant.

The public surface is unchanged (identities() still returns a slice;
new() has the same signature), and cloning a resolution or generation
is now a refcount bump instead of a deep identity-list copy.

On the profiled monorepo (1,226 workspaces, 802 distinct closures),
package graph construction drops from ~270ms to ~249ms median (~8%),
with a proportional cut in identity-list allocations; repos with more
homogeneous workspaces (e.g. many generated packages with identical
dependencies) share more and save more.

perf: Parallelize resolution fingerprint hashing (#13642)
95f2297 
### Description

> **Stacked on #13641** (shared resolution identity lists). Base branch
is `claude/perf-shared-resolution-identities`; review/merge #13641
first. The diff shown here is only this PR's commit.

Building an external resolution generation fingerprints every
workspace's package resolution: one Cap'n Proto canonicalization plus an
xxHash64 over its sorted `(key, version)` sequence. Profiling a large
real-world monorepo (~1,200 workspaces) showed this loop as the dominant
cost of `ExternalResolutionGeneration::build` — ~41 ms of a ~56 ms phase
— and it ran **sequentially**.

#13641 made packages that share an identity list share its `Arc`.
Building on that, this PR fingerprints each **distinct** list exactly
once (keyed by slice address) and hashes those distinct lists **in
parallel** with rayon. Each list is an independent hash; only the
borrowed identity slices cross into the parallel iterator, while the
slice-pointer dedup keys stay on the sequential side.

Output is byte-identical to sequential: the canonical bytes are
deterministic per input, packages are re-sorted deterministically
afterward, and the cache-compatibility-critical hash algorithm and byte
layout are untouched — only the iteration changes.

**Measured** (4-core machine, ~1,200-workspace repo, release, 8 warm
samples per side): package graph construction ~249 ms (shared lists
alone) → ~213 ms median with this on top, versus ~264 ms on the
pre-stack base. The fingerprint phase itself falls from ~41 ms to
single-digit ms; the speedup scales with core count. Small repos are
unaffected (rayon runs tiny inputs effectively serially), and `build`
already executes inside the discovery `block_in_place` region where
manifest parsing is likewise parallelized.

### Testing Instructions

- `cargo test -p turborepo-repository` — all 419 tests pass, including
the fingerprint-stability tests (hash input and algorithm unchanged;
only the loop is parallel).
- `cargo clippy -p turborepo-repository --all-targets` is clean.

perf: Build resolution identity lists in parallel (#13643)
58e4e8a 
### Description

> **Top of a 3-PR stack** → #13641 (shared identity lists) → #13642
(parallel fingerprint) → this. Base branch is
`claude/perf-parallel-fingerprint`; review/merge the two below first.
The diff shown here is only this PR's commit.

After #13641 made identical closures share one `Arc`-backed identity
list and #13642 parallelized fingerprinting, the largest remaining cost
in `resolve_dependencies` is building the identity lists themselves: a
`String` clone for each closure member's key and version, plus a
lockfile `human_name` lookup — repeated across every distinct closure
(~800 of them, ~300 members each, on the profiled repo). Measured at ~45
ms, it was the single biggest remaining lever in package-graph
construction.

This builds the lists for the **distinct** closures in parallel with
rayon. Distinct closures are bucketed sequentially by their `Arc`
pointer sequence (the raw pointers never leave that side); only the
borrowed closure slices cross into the parallel build. The sort/dedup
invariant now lives in one place —
`PackageResolution::shared_identity_list`, used by both `new()` and the
parallel path — so `from_shared` stays consistent.

Output is unchanged: each list is sorted/deduped identically and
attributed to the same packages; only wall-clock changes.

**Measured** (4-core machine, ~1,200-workspace repo, release, warm
samples): identity construction ~45 ms → ~12 ms, taking package graph
build from ~213 ms (rest of the stack) to **~178 ms median — ~33% below
the ~264 ms pre-stack base**. Scales with core count; small repos are
unaffected. This runs inside the discovery `block_in_place` region,
consistent with the already-parallel manifest parsing and the #13642
fingerprint loop.

### Testing Instructions

- `cargo test -p turborepo-repository` — all 419 tests pass; package
counts and resolutions are identical (verified against two real
monorepos: 1,226 and 143 workspaces, package counts unchanged).
- `cargo clippy -p turborepo-repository --all-targets` is clean.

### Full stack summary

On the ~1,200-workspace repo, the three PRs together cut package-graph
construction from **~264 ms to ~178 ms (~33%)**: shared lists
(~264→249), parallel fingerprint (~249→213), parallel identity build
(~213→178).

perf: Intern resolution identities as Arc&lt;str&gt; across closures (#…
6af5423 
…13645)

### Description

> **4th entry in the resolution stack** → #13641 → #13642 → #13643 →
this. Base is `claude/perf-parallel-identity-build`; review the three
below first. The diff shown here is only this PR's commit.

A shared dependency appears in the transitive closure of many
workspaces. Even after #13641/#13643 share identity *lists* across
identical closures, building each distinct closure's list still cloned
every member's `key` and `version` strings and re-ran the lockfile
`human_name` lookup — so a package appearing in N distinct closures
allocated its identity N times.

**dhat pinpointed this as the single largest allocation source** in
package-graph construction: three sites at ~386,800 blocks each
(`key.clone()`, `version.clone()`, `human_name()`) — ~1.16M allocations,
over half the total.

This stores `ExternalPackageIdentity`'s `key`, `version`, and
`human_name` as `Arc<str>` and interns one identity per distinct
package. The shared closure DP already hands us the same `Arc<Package>`
everywhere a package occurs, so identity is bucketed by `Arc` pointer:
each distinct package's strings are allocated once (in parallel), and
every closure that contains it clones a refcount-bumped identity instead
of re-cloning strings. Raw pointers stay on the sequential bucketing
side; the parallel identity build and list assembly only touch `Sync`
data.

Public surface unchanged: `new()`/`with_human_name()` still accept
anything `Into<Arc<str>>` (both `String` and `&str` qualify, so existing
callers — cargo, uv, tests — compile untouched), and the accessors still
return `&str`.

**Verified with dhat** on a ~1,200-workspace pnpm monorepo
(`dhat::HeapStats` around `PackageGraphBuilder::build`):

| | heap allocations | bytes |
|---|---|---|
| `main` | ~2,128,000 | ~300 MB |
| stack (#13641→#13643) | ~1,876,000 | ~268 MB |
| **+ this PR** | **~989,000** | **~238 MB** |

This PR alone removes **~887,000 allocations** (47% of what remained)
and ~30 MB. Wall-time is within noise on a warm 4-core box, but fewer
allocations is a real reduction in allocator work and memory pressure
that compounds on constrained CI runners, slower allocators, and larger
repos.

### Testing Instructions

- `cargo test -p turborepo-repository` — all 419 tests pass, including
resolution/fingerprint tests. Identities are *shared*, not changed: same
`(key, version)`, same ordering, same fingerprints.
- `cargo clippy -p turborepo-repository --all-targets` is clean.
- Allocation reduction reproduced with a dhat-instrumented harness
around `PackageGraphBuilder::build`.
