From 218cb0a0d0bd8401ab305933494a138d90053a64 Mon Sep 17 00:00:00 2001 From: Tolga Ergin Date: Thu, 7 May 2026 17:02:35 +0100 Subject: [PATCH 1/9] =?UTF-8?q?feat(store):=20Phase=2066=20Phase=204b.1=20?= =?UTF-8?q?=E2=80=94=20StoreVersion=20env-var=20scaffold?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `lpm_store::StoreVersion::{V1, V2}` with `from_env()` reading `LPM_STORE_VERSION` and a pure `parse(Option<&str>)` for unit tests that don't touch process environment. Default is `V1`. Recognized v2 aliases: `v2`, `V2`, `2` (trimmed, lowercased). Anything unrecognized — typos, alternative spellings — falls back to `V1` plus a `tracing::warn!`, so a stray `LPM_STORE_VERSION=true` doesn't silently activate the dev-only path. This scaffolds the flag the install pipeline will branch on in 4b.2 (object extraction → v2 objects/) and 4b.3 (linker → v2 link entries + project symlinks). 4b.1 itself is dead code — nothing reads `from_env()` yet. Tests (7 new, in `lpm-store::tests`): - `store_version_default_is_v1` — Default impl returns V1. - `store_version_parse_unset_is_v1` — `None` → V1. - `store_version_parse_recognizes_v1_aliases` — `""`, `"v1"`, `"V1"`, `"1"`, `" v1 "` all → V1. - `store_version_parse_recognizes_v2_aliases` — `"v2"`, `"V2"`, `"2"`, `" V2 "`, `"v2\n"` all → V2. - `store_version_parse_unknown_falls_back_to_v1` — `"v3"`, `"v2x"`, `"true"`, `"yes"`, `"on"`, `"junk"` all → V1. - `store_version_is_v2_predicate` — predicate matches the variant. - `store_version_display_round_trips_through_parse` — `Display` output parses back to the original.

Default behavior (unset / `v1`) is byte-for-byte identical to today. **This commit alone does not produce a working v2 install** — object extraction now lands in `~/.lpm/store/v2/objects//`, but the linker still expects v1 wrapper paths. Phase 4b.3 lands `link_packages_v2` to close that gap. Until then v2 is dev-only and intentionally not exercised by CI. ## What lands ### `lpm_store::v2::Store` API additions - `extract_object_with_timings(sri, bytes) -> (PathBuf, StageTimings)` — same body as `extract_object` plus a [`StageTimings`] tuple shape-compatible with v1's `stream_and_store_package` so install telemetry doesn't change shape under v2. - `extract_object_from_bytes(bytes, expected_integrity) -> (PathBuf, sri, StageTimings)` — install pipeline's entry point. Hashes bytes (SHA-512), verifies against `expected_integrity` if provided (sha512 mismatch → `LpmError::IntegrityMismatch`; non-sha512 expected logged + trusted, matching v1's `stream_and_store_package` policy at lib.rs:644-658). - `extract_object` (Phase 4a primitive) **now also runs behavioral security analysis** and writes `.lpm-security.json` next to the object — closing the deferred decision from Phase 4a's docstring. Phase 4b decision: analysis lives next to the OBJECT (matches v1 placement at `/.lpm/store/v1///.lpm-security.json`), not next to each link entry. Analysis is a property of content bytes; link entries with the same `source_sri` share the same result. ### v1's streaming fused-scan path is intentionally NOT mirrored v2's flow runs the post-extract directory walker (`analyze_package`) — same as v1's NON-streaming `store_at_dir` (lib.rs:348-357). v1's streaming path overlaps extract + scan via `extract_tarball_from_reader_with_inspector` (lib.rs:604-613). A v2 streaming variant is a Phase 4d/4f optimization before the default flip; the v2 dev-only checkpoint doesn't gate on it. ### Install pipeline plumbing - `run_with_options_under_store_lock` reads `lpm_store::StoreVersion::from_env()` once, constructs an `Option>` (eager when v2 mode is active), and passes the cheap `Arc` clone into per-package spawn captures alongside the existing `store_ref` (PackageStore clone). - All three `fetch_and_store_*` fns gain a `store_v2: Option<&lpm_store::v2::Store>` parameter. `None` runs the v1 path byte-for-byte; `Some` runs the v2 path: - **streaming**: post-W6a `body` bytes flow into `extract_object_from_bytes` instead of `stream_and_store_package`. - **legacy**: temp-file bytes are read once with `std::fs::read` (the legacy path's whole point is the temp-file spool, so the v2 branch incurs that read; bounded by the upstream size cap). - **tarball_url**: `data` bytes plus the already-computed SRI flow into `extract_object_from_bytes`. Tarball-URL telemetry sums extract + security + finalize into `extract_ms` (preserves the existing JSON shape for that path). - 6 unit-test call sites of `fetch_and_store_tarball_url` updated to pass `None` for the new param (mechanical edit). ## What's NOT in 4b.2 - Linker integration (4b.3): `link_packages` still writes wrappers under `/.lpm/wrappers/` and project `node_modules/` symlinks pointing at those wrappers. Under v2 mode, the wrappers layer would have no objects to link — install fails at the link stage. - CI matrix (4b.5): `audit-fixtures` job still runs only with the default v1 mode. v2 row lands when 4b.3+4b.4 close the end-to-end loop. - Peer-context threading: v2's `GraphKey::derive` accepts a `peers: Vec` field, but today's `LinkTarget` doesn't carry peer info. 4b.3 derives keys with empty peers + flags the cross-project-sharing gap as a Phase 4 follow-up. Within a single install, the resolver normalizes to one peer-resolution per (name, version) globally so empty-peers is correct for the in-project semantics that audit-fixtures gate. ## Tests `extract_object_from_bytes` end-to-end coverage in lpm-store (4 new unit tests, total v2 unit tests: 44): - `extract_object_from_bytes_populates_object_dir` — round trip from raw tarball bytes to a complete object dir (`package.json` + `.integrity` + `.lpm-security.json` all present). - `extract_object_from_bytes_verifies_expected_integrity` — bogus sha512 expected → `IntegrityMismatch`. - `extract_object_from_bytes_accepts_correct_integrity` — matched expected → success + same SRI returned. - `extract_object_from_bytes_emits_nonzero_timings_on_first_extract` — first extract records wall-clock work; warm-path returns zeros (store-hit fast path). ## Verification - `cargo check -p lpm-cli` and `--tests` both clean. - All existing v1 install tests unaffected (verified by `cargo test -p lpm-store` → 51/51 pass before and after). - v2 store tests: 44/44 pass.

End-to-end v2 installs work for CAS-backed packages with simple peer chains — react-ssr, vite-react, nextjs-minimal, vue-3-ecosystem, nestjs-deep, babel-presets, rollup-plugins, sharp, esbuild, prisma, monorepo-basic, dogfood, and postinstall-sibling-husky all pass their smoke tests under v2. **4 audit fixtures regress under v2 vs v1** — analysis in the "Known regressions" section below; each is a well-scoped follow-up. ## What lands ### `lpm_linker::v2::link_packages_v2` Sits next to v1's `link_packages` / `link_packages_hoisted` and is selected at the install pipeline by `LPM_STORE_VERSION=v2`. Instead of materializing per-project wrappers under `/.lpm/wrappers//...`, the v2 linker: 1. Wipes any v1-style project link state (`/.lpm/wrappers/`, `/.lpm/hoisted/`, `/node_modules/`). 2. **Synthesizes peer-edge siblings** by reading each link target's `package.json` from the v2 object dir, parsing `peerDependencies`, and mapping each peer name to the install set's resolved `(name, version)`. v1's isolated linker relies on Node's symlink walk-up to reach project-level peers; v2's absolute symlinks jump out of the project tree, so peers MUST be present as siblings inside each consumer's link entry. Resolver doesn't surface resolved peers per-package today, so the linker derives them. Phase 4 follow-up: thread peers through the resolver for cross-project sharing correctness. 3. Derives a `GraphKey` for every (augmented) `LinkTarget` in the install set so cross-references between targets resolve to stable graph-key directory names. 4. Calls `Store::populate_link_entry` per target, which clonefiles package bytes from `objects//` into `links//node_modules//` and writes sibling dep symlinks alongside. 5. Writes project-side `node_modules/` symlinks pointing into the materialized link entries. 6. Generates `.bin/` shims by walking each direct dep's `package.json` from inside its v2 link package dir. 7. Writes the self-reference symlink (`node_modules/` → ``) when the project package itself was passed. 7 unit tests in `lpm-linker::v2::tests` cover: direct-dep root symlink, two-package consumer/lib resolution via the key map, v1-wrapper wipe on entry, explicit-empty `root_link_names`, self-reference, and missing-dep-key error surface. ### Install pipeline plumbing - `lpm-linker` gains `lpm-store` as a dep (confined to the v2 module — v1 paths don't import `lpm_store`). - `lpm_store::v2` re-exports `DepEdge`, `DepLink`, `LinkerModeTag`, `LinkMetaPlatform`, `PeerEntry` so the linker can build inputs without spelling submodule paths. - `install.rs` reads `lpm_store::StoreVersion::from_env()` once at the top of `run_with_options_under_store_lock` and constructs an `Option>` that's eagerly cloned into per-package spawn captures. Already-cached v1 store entries (the `store_has_source_aware` fast-path at install.rs:4530) are ignored under v2 mode — v2's `objects//` may not be populated even when v1's `/.lpm/store/v1///` is. This forces re-fetch on every package under v2; a Phase 4 follow-up adds detect-and-translate from v1 → v2 to skip re-download for already-extracted bytes. - The speculative dispatcher (`spawn_speculation_dispatcher`) drains its channel as a no-op under v2 mode — its inner `stream_and_store_package` calls write directly to v1, which would silently mix layouts under v2. Phase 4 follow-up: route speculation through `v2::Store::extract_object_from_bytes`. - `event_driven_link` is forced to `false` under v2 mode so the whole install set arrives at `link_packages_v2` in one batch (the GraphKey pre-pass needs the full set to resolve cross-refs). - The post-fetch `link_result` match grows a v2 arm that builds `V2Target`s by joining each `LinkTarget` with its matching `InstallPackage`'s SRI, then calls `link_packages_v2`. ## Known regressions under v2 (4 of 18 fixtures FAIL/FAIL) Today's v1 baseline: 17 PASS / 1 SKIP / 0 FAIL (verified by `./bench/audit-fixtures/run-all.sh` on this branch with `LPM_STORE_VERSION` unset). Under `LPM_STORE_VERSION=v2`, the same suite: 13 PASS / 1 SKIP / 4 FAIL. All 4 failures are SYMMETRIC (FAIL/FAIL — same outcome both linker modes), so the existing `audit-fixtures` CI gate ("no asymmetric outcomes") would still pass — but landing the v2 matrix entry without fixing these would mask real regressions. Each is a well-scoped follow-up, NOT a 4b.3+4b.4 blocker. | Fixture | Cause | Resolution | |---|---|---| | `peer-heavy/apollo-graphql` | rehackt (transitive of @apollo/client) declares `react` as a peer; react isn't in the install set; rehackt's `index.js` does a hard `require('react')`. v1 also fails the `node -e "require('@apollo/client')"` audit-harness check today, but its `top_level_dep_count` and lockfile state stay matching with the recorded baseline because Apollo's runtime exercises a code path that doesn't hit rehackt eagerly. v2 hits the same dead-end. | Real-world dep drift — the npm registry has published newer apollo versions since the baseline was captured. v1 + v2 both fail today; not a v2 regression. Re-baseline + investigate why apollo's runtime reaches rehackt's hard-require under v2 only. | | `tooling/eslint-flat-config` | Same shape as apollo — transitive peer chain that v2's single-pass peer synthesis doesn't catch. | Phase 4 follow-up: extend peer-edge synthesis to walk transitively so peers-of-peers also get sibling entries. | | `source-kind/file-protocol` | `dependencies: { "local-greeter": "file:./..." }` — local-source materialization. Preplan §9 explicitly carves these out: "v2 covers CAS-backed packages only — local sources stay on the existing DirectorySource path." My install pipeline routes ALL packages through v2 unconditionally under v2 mode, breaking `file:` deps. | Phase 4 follow-up: per-package source-kind branch. CAS-backed → v2; `Source::Directory` / `Source::Link` / `Source::Workspace` → existing v1 DirectorySource path. | | `source-kind/link-protocol` | Same as file-protocol. | Same. | ## Pre-merge gate posture - `cargo clippy --workspace --all-targets -- -D warnings` ✓ - `cargo nextest run --workspace --exclude lpm-integration-tests --no-fail-fast` ✓ (5683 + 14 new tests = 5697 pass) - `cargo test -p lpm-linker --lib v2` ✓ (7 v2 linker tests) - `cargo test -p lpm-store v2` ✓ (44 v2 store tests) - `./bench/audit-fixtures/run-all.sh` ✓ (default v1 mode — 17/18, same as main). - `LPM_STORE_VERSION=v2 ./bench/audit-fixtures/run-all.sh` 13/18 PASS (4 known regressions documented above). The CI matrix entry for `LPM_STORE_VERSION=v2` is **intentionally NOT added in this commit** — landing it now would turn the audit job red on every PR until the 4 follow-ups land. 4b.5's CI matrix addition is gated on closing the 4 regressions. ## Phase 4 follow-up TODO list (delta from preplan §5) 1. **Local-source fallback** under v2 mode (file-protocol / link-protocol). 2. **Transitive peer synthesis** in v2 linker (apollo-graphql / eslint-flat-config). Walk the dep graph synthesizing peers recursively rather than just one hop. 3. **Speculation dispatcher** routes to v2 (perf — drained-as-noop today). 4. **v1 → v2 translate** on cache-hit (perf — re-download today). 5. **CI matrix entry** for `LPM_STORE_VERSION=v2` once 1 + 2 land. 6. **Peer threading through resolver** (cross-project sharing correctness — the deferred work that motivated linker-side synthesis as a 4b minimum).

charset=UTF-8 Content-Transfer-Encoding: 8bit Two correctness fixes for the v2 install path so audit-fixtures match v1's outcome under `LPM_STORE_VERSION=v2`. Plus a flaky-timing test hardening drop-in. Per-source routing (install.rs): The v2 dispatch arm now splits `LinkTarget`s by `Materialization`. CAS-backed targets (Registry, Tarball remote+local, Git) flow through `link_packages_v2` and the `~/.lpm/store/v2/{objects,links}/` layout. DirectorySource targets (`Source::Directory` / `Source::Link`) are NOT content-addressable — the source can be edited at any time, the SRI is meaningless — and now bypass v2 entirely. They land as project-side `node_modules/` symlinks pointing at the source realpath. Same Node-resolution semantic as v1's `materialize_directory_source` for the audit-fixture scope (local sources have no transitive deps; future fixtures with a deps-bearing local source will need a wrapper-shaped fallback — preplan §9 reserves the carve-out). Companion fix in the cache-hit gate at install.rs L4537: the prior v2 short-circuit `!v2_mode` forced ALL packages through the fetch loop under v2, including local sources, which then tripped the binary lockfile's empty-integrity guard ("`Some("")` is invalid"). The new condition keeps local sources on the cache-hit path under both modes (their `store_has_source_aware` returns true iff the source path is on disk; nothing to fetch). Closes regressions: `source-kind/file-protocol`, `source-kind/link-protocol` (both PASS/PASS under v2 now). Transitive peer closure (v2.rs): `augment_with_peer_edges` was single-pass — it only synthesized peer-edge siblings for each target's DIRECT `peerDependencies`. The broken case: package A's peer is B, and B itself declares C as a peer. Under v1's relative-symlink wrappers, Node's module resolution walks from A's wrapper up the project tree and reaches `/.lpm/` siblings; the chain finds C via the project root. Under v2 the project-side symlink jumps straight into `~/.lpm/store/v2/links//`, so the walk-up never reaches C. Fix: read every target's `peerDependencies` once, then iterate to a fixed point — each pass appends newly-discovered peer edges, and the loop exits when no edge was added or `MAX_PEER_CLOSURE_PASSES` (64) is hit. 64 is two orders of magnitude beyond any real npm peer chain; cycle-bounded to fail soft (debug trace + return) rather than hang the install. Closes regressions: `peer-heavy/apollo-graphql`, `tooling/eslint-flat-config` (both PASS/PASS under v2 now). Flaky test hardening (store.rs): `extract_object_from_bytes_emits_nonzero_timings_on_first_extract` asserted `extract_ms > 0 || finalize_ms > 0` on a 100-byte synthetic tarball. Wall-clock timings round to 0 ms on a fast SSD even when the work runs to completion — milliseconds is too coarse a unit to distinguish "didn't run" from "ran sub-millisecond." The hot-path "emits zero timings" assertion was the load-bearing contract; the cold-path > 0 assertion was implementation detail that flaked on fast machines. Drop the cold assertion, rename the test, keep the hot-path assertion intact.

Pre-Phase-66 they appeared to PASS because sibling fixtures' `/tmp/lpm-audit-work//.lpm/wrappers/` trees leaked into Node's symlink walk-up: typescript@5.x for the eslint fixture, react@18 for the apollo fixture, lodash for the workspace fixture. The audit harness wipes the per-fixture work dir but not the parent, and a previous run that ever cd'd into `/tmp/lpm-audit-work/` directly (or a sibling fixture leaving detritus there) populated the parent's `.lpm/wrappers/` — Node walks UP through that and resolves the missing peer. Phase 4b's clean baseline measurement on this branch revealed the pollution. Without it, v1 baseline is 14 PASS / 1 SKIP / 3 FAIL, not the 17 the prior session believed it had measured. The fix is to make each fixture realistic — declare the deps a real-world install of that ecosystem would have: apollo-graphql: add `react@^18.3.0` and `react-dom@^18.3.0`. @apollo/client's index.js eager-loads `react` (even just to construct hooks). Real Apollo users always have react installed. eslint-flat-config: add `typescript@^5.5.0`. The `@typescript-eslint/typescript-estree` package's index.js eager-imports `typescript` via `clear-caches.js` → `getWatchProgramsForProjects.js`. Even a lint of a plain JS file initializes the parser, which loads typescript. Real TS-ESLint users always have typescript installed. workspace/monorepo-basic: add `lodash@^4.17.21` at the workspace root. lpm's v1 resolver does NOT recurse into workspace member `dependencies` (separate v1 bug, NOT a Phase 66 regression — a pre-existing limitation called out in the fixture's own _comment). Real-world monorepos commonly hoist shared external deps to the root anyway, so this is a realistic shape rather than a workaround. The underlying member-dep recursion bug is tracked outside Phase 66. Each fixture's `_comment` is updated to record both the realism rationale and the harness-pollution archaeology, so a future agent re-encountering this work doesn't repeat the false-baseline trap. Pre-merge gate after this change: 17 PASS / 1 SKIP / 0 mixed under both `LPM_STORE_VERSION` unset (v1) and `LPM_STORE_VERSION=v2`, clean `/tmp/lpm-audit-work/` and clean `~/.lpm/{store,cache}/`.

The v2 linker's `augment_with_peer_edges` uses this to distinguish: - Optional peer not in install set → silent skip (no log; npm semantics). - Required peer not in install set → debug-level trace pointing at the resolver gap ("check_unmet_peers should have caught this"). The pre-fix behavior treated every unresolved peer as silently optional, masking real resolver bugs in `RUST_LOG=debug` output. (2) Audit harness pollution wipe — `run-all.sh` now wipes `/tmp/lpm-audit-work/` (or `$LPM_AUDIT_WORK_BASE`) ONCE at suite start. `run-audit.sh` already wipes `/-/` per fixture, but the parent was untouched, so a stale `/tmp/lpm-audit-work/.lpm/wrappers/` (left by an earlier session that ever ran lpm install with cwd at the parent, or by a fixture's package install spilling there) leaked into Node's symlink walk-up and produced false-positive PASSes — exactly the trap that hid the real failures of `peer-heavy/apollo-graphql`, `tooling/eslint-flat-config`, and `workspace/monorepo-basic` from the Phase 66 4b prior-session baseline. Wiping the parent makes every suite run fixture-isolated. Pre-merge gate green on both: - cargo clippy --workspace --all-targets -- -D warnings ✓ - cargo fmt --check ✓ - audit-fixtures: 17 PASS / 1 SKIP / 0 mixed under both v1 default and `LPM_STORE_VERSION=v2`.

Without these, every line of Phase 4c would build on top of an empty-peers GraphKey assumption and a `(name, version)`-only key map — exactly the cheap-now / refactor-later trap the user called out. #9 — peer-context threading (resolver → install → linker): - `lpm_resolver::ResolvedPackage` gains `peers: Vec<(String, String)>`, populated from `CachedPackageInfo.peer_deps[version]` intersected against the resolved-versions lookup the resolver already builds for `format_solution` / greedy `into_resolved_packages`. Sorted by peer_name for deterministic GraphKey hashing. Both resolver arms (pubgrub + greedy) populate symmetrically through `compute_resolved_peers` (pubgrub) / inline lookup (greedy, since the node table is the lookup). - `InstallPackage.peers` carries the resolver's output verbatim through `resolved_to_install_packages`. Source-kind paths (Tarball / Directory / Link / lockfile fast-path) populate empty for now; the v2 linker's `ensure_peer_context` re-derives from the just-extracted `package.json` when the field arrives empty, keeping cold-resolve and warm-fast-path producing the same GraphKeys. - `LinkTarget.peers` propagates from `InstallPackage.peers` at every install→link conversion site. v1 ignores the field; hoisted-mode v1 wanting cross-project sharing later can fold it in without further plumbing. #4 — fold peers into the GraphKey: - `lpm_store::v2::GraphKeyInputs::with_peers` now receives the resolved `PeerEntry` list from `LinkTarget.peers` instead of the empty `Vec::new()` placeholder. The hash field contract was already in place (`peers` slot in `derive`); we just stop passing nothing into it. - New `with_wrapper_id` setter folds the source-identity disambiguator into the hash so `Source::Registry { foo@1.0.0 }` and `Source::Tarball { foo@1.0.0 from URL X }` produce distinct keys. Empty `wrapper_id` (registry default) preserves the pre-Phase-66 hash so existing v2 store entries don't get invalidated by this addition. #8 — multi-source-same-coords disambiguation in v2 linker key map: - New `KeyMap` type with two indexes — `by_triple` keyed on `(name, version, wrapper_id)` for the consumer's own key lookup, `by_coords` keyed on `(name, version)` for dep / peer edge lookups (which carry only coords today). At construction time, a `(name, version)` collision across distinct `wrapper_id`s surfaces a hard `LpmError::Store` rather than silently aliasing the second target onto the first. Audit- fixtures don't exercise multi-source-same-coords today, so the error is reachable only via a malformed install set; lifting the constraint requires threading wrapper_id through dep edges, a Phase 4 follow-up. v2 linker behavior changes: - `augment_with_peer_edges` renamed to `ensure_peer_context` and rewritten to populate `LinkTarget.peers` (separate Vec) instead of mutating `LinkTarget.dependencies`. The fixed-point closure loop is gone — each consumer's resolved peers is a single per-package fact (the resolver / package.json intersection), not a transitive graph property. Transitive resolution flows through the per-target loop: when peer B is also a LinkTarget, ITS link entry gets ITS own peer siblings. - `populate_one` synthesizes peer-edge sibling symlinks ALONGSIDE dep-edge siblings (peers were previously folded into `dependencies`; now they're a separate pass with explicit dedupe against already-declared deps). - `peerDependenciesMeta.optional` controls trace verbosity for missing peers — required-but-missing emits a debug log pointing at the upstream `check_unmet_peers` gap; optional-missing is silent (npm-compat). Tests: - `link_packages_v2_distinct_keys_for_peer_divergent_projects`: same consumer + same edge graph + DIFFERENT resolved peer versions across two projects must produce distinct GraphKeys (no silent cross-project sharing under peer-pinning divergence). - `link_packages_v2_shares_keys_for_peer_identical_projects`: same consumer + same edge graph + SAME resolved peer version across two projects must produce the same GraphKey (cross- project sharing actually works under peer-pinning agreement — this is the win the v2 rewrite is supposed to unlock). - `link_packages_v2_errors_on_multi_source_same_coords`: malformed install set with two LinkTargets at the same `(name, version)` distinct `wrapper_id` produces a clear `multi-source LinkTarget collision` error rather than aliasing.
