From 9b898b1a556f16f29733a1ec9a9920840b2e6c94 Mon Sep 17 00:00:00 2001 From: Mikola Lysenko Date: Fri, 22 May 2026 11:41:53 -0400 Subject: [PATCH 01/72] =?UTF-8?q?feat(apply):=20safety=20primitives=20?= =?UTF-8?q?=E2=80=94=20lock,=20CoW,=20atomic=20write,=20sidecar=20fixups?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds five new modules to `socket-patch-core` and refactors `apply_file_patch` to compose them safely with #79's perm-preservation: - **`patch::apply_lock`** — cross-platform advisory file lock at `<.socket>/apply.lock` via `fs2`. Used by every mutating subcommand to serialize against concurrent socket-patch runs. - **`patch::cow`** — hardlink + symlink copy-on-write. Before patching, if `filepath` is a symlink into a content-addressed store (pnpm) or a regular file with `nlink > 1` (bazel mirrors, nix store overlays), give this project a private inode. The pnpm content store and every other project pointing at it stay byte-identical. - **`patch::sidecars`** — ecosystem-aware sidecar fixups dispatched from `apply_package_patch`. Cargo: rewrite `.cargo-checksum.json` with new SHA256s so `cargo build` accepts patched sources. NuGet: delete `.nupkg.metadata` (the documented "unknown" state vs. a stale `contentHash` that would flag tampering). PyPI / gem / Go: advisory-only — surface a one-line note about downstream tooling consequences. - **`crawlers::pkg_managers`** — path-based detector for the four Node.js layout flavors (npm / pnpm / yarn-classic / yarn-berry PnP). Apply uses this to refuse yarn-berry PnP (packages live in `.yarn/cache/*.zip`) and to surface a pnpm-detected note. - **`apply_file_patch` atomic rewrite** — two-phase commit: 1. Hash `patched_content` in memory; error out before any disk write if it doesn't match `expected_hash`. Removes the prior "wrote bytes, post-write verify failed, can't restore" window. 2. CoW the target if it's a shared inode. 3. Stage write to `/.socket-stage-`, `sync_all()`, then `rename(stage, target)`. POSIX `rename(2)` is atomic — observers see either the old or new bytes, never a truncated half-write. Composes cleanly with #79's mode + uid/gid restore step which now operates on the post-rename inode. `ApplyResult` grows `sidecars_updated: Vec` and `sidecar_advisory: Option` so the CLI envelope can surface fixup outcomes. `fs2` and `tempfile` added to socket-patch-core dependencies. Two new tests pin the headline invariants: - `test_apply_file_patch_hash_mismatch_leaves_original_intact` — atomic-write contract: hash mismatch leaves target byte-identical AND no `.socket-stage-*` litter in parent dir. - `test_apply_file_patch_does_not_propagate_to_hardlinked_sibling` — the pnpm content-store invariant at the integration level. Plus 10 unit tests for cow + apply_lock and 13 for sidecars/* + 9 for pkg_managers.

Takes `Command` so the failure envelope's `command` field reflects which subcommand was blocked. On contention the binary emits `{status: "error", error: {code: "lock_held", ...}}` in JSON mode or a one-line stderr message otherwise, then exits 1. **Lock acquisition** added to `apply`, `rollback`, `repair`, `remove` immediately after the manifest existence check. `remove`'s outer lock spans the inner `rollback_patches` call (which deliberately does NOT acquire the lock so the composition doesn't self-deadlock). **Apply pkg-manager gating** — after the lock, `apply` runs `detect_npm_pkg_manager`: - `YarnBerryPnP` → emit `EnvelopeError("yarn_pnp_unsupported", ...)` pointing at `yarn patch` and exit 1. - `Pnpm` → surface a one-line stderr note. CoW handles the substantive safety work; this just tells the user the layout was understood. **Sidecar JSON via `event.details`** — `result_to_event` extends the Applied event with `details.sidecarsUpdated: string[]` and `details.sidecarAdvisory: string | null` when either is non-empty. Narrower JSON-envelope contract than first-class fields; consumers read `event.details.sidecarsUpdated` from JSON. **Maven + NuGet experimental runtime gates** in `ecosystem_dispatch.rs`. Even when compiled with `--features maven`/`nuget`, the crawlers refuse to dispatch unless the matching `SOCKET_EXPERIMENTAL_MAVEN=1`/`SOCKET_EXPERIMENTAL_NUGET=1` env var is set. Without it, surface a warning event and skip those PURLs. Reasoning: Maven patches corrupt jar sidecar checksums (sha1/md5); NuGet patches corrupt `.nupkg.sha512` signature sidecars that `dotnet restore` reads as tamper-evidence. `fs2` added to socket-patch-cli dev-dependencies for the lock e2e test (same crate the binary uses internally).

Test holds the same `.socket/apply.lock` the binary uses via `fs2` directly, then spawns `socket-patch apply` and asserts the second process exits with `error.code == "lock_held"`. Zero production-code hooks. - `e2e_safety_yarn_pnp.rs` (5 tests, non-ignored). Yarn-berry PnP markers (`.pnp.cjs`, `.pnp.loader.mjs`) trigger `error.code == "yarn_pnp_unsupported"`. Negative control: plain npm layout does NOT trigger the refusal. - `e2e_safety_cargo_build.rs` (5 tests, `#[ignore]` + `--features cargo`). Three synthetic-vendor tests: 1. Baseline `cargo check --offline --frozen` succeeds. 2. Negative control — mutating the source WITHOUT the sidecar fixup makes cargo refuse with "checksum changed". Proves cargo actually verifies, which is what makes the positive test meaningful. 3. Sidecar fixup makes `cargo check` pass; `.cargo-checksum.json` is rewritten and the `package` field is preserved. 4. JSON envelope contract: `.cargo-checksum.json` appears in `event.details.sidecarsUpdated`. Plus `traitobject_real_socket_patch_round_trip` — the cargo layer-2+3 combined test: `cargo fetch traitobject@0.0.1` from crates.io → `socket-patch get b15f2b7f-d5cb-43c9-b793-80f71682188f` from patches-api.socket.dev → assert `.cargo-checksum.json` rewritten + `cargo check` succeeds against the real, production Socket patch. - `e2e_safety_pnpm.rs` (4 tests, `#[ignore]`). Two projects share a pnpm content store via `--config.package-import-method=hardlink`. `socket-patch get` in project A patches A; project B + store entry stay byte-identical. `pnpm install --frozen-lockfile` in B afterwards does not revert A. Exercises CoW against a real pnpm install rather than a hand-rolled hardlink. **`tests/common/mod.rs`** — shared helpers (`binary`, `run`, `assert_run_ok`, `git_sha256`, `sha256_hex`, `pnpm_run`, `cargo_run`, `write_minimal_manifest`, `write_blob`, `parse_json_envelope`, `envelope_error_code`, `envelope_error_message`) lifted from the duplicated copies in `e2e_npm.rs` etc. Additive; existing suites keep their inlined copies for now. **CI matrix** in `.github/workflows/ci.yml`: - `e2e_safety_cargo_build` on ubuntu + macos + windows - `e2e_safety_pnpm` on ubuntu + macos + windows (pnpm-on-Windows uses junctions + copies by default, so the CoW invariant holds vacuously; the test still runs to verify apply doesn't error on Windows. Semantic Windows nlink coverage is a follow-up — `std::fs::Metadata` doesn't expose nlink on Windows without `GetFileInformationByHandle` via `windows-sys`.) - New `Setup pnpm` step (`npm install -g pnpm@10`) gated on the pnpm suite. The fast non-ignored suites (`e2e_safety_lock`, `e2e_safety_yarn_pnp`) run via the standard `test` job on all three platforms. **Existing-test contract updates** (these tests were pinning the old, broken behavior; both still describe correct invariants — their assertions just needed to track the rebased semantics): - `tests/apply_invariants.rs`: `dir_hash` excludes `apply.lock`. The lock file is deliberate ephemeral session state, not patch content; the "apply is read-only against .socket/" invariant is about manifest + blobs + diffs + packages. - `tests/in_process_edge_cases.rs`: `apply_blob_after_hash_mismatch_reports_failure` now asserts the atomic-write contract — the target file is byte-identical to its pre-call state on the hash-mismatch failure path, no half-written corruption.

Unit tests pin the JSON contract. ## JSON shape (consumer view) ```json { "command": "apply", "events": [...], "sidecars": [ { "purl": "pkg:cargo/...", "ecosystem": "cargo", "files": [{"path":".cargo-checksum.json","action":"rewritten"}] }, { "purl": "pkg:nuget/...", "ecosystem": "nuget", "files": [{"path":".nupkg.metadata","action":"deleted"}], "advisory": { "code":"nuget_signed_package_tampered", "severity":"warning", "message":"..." } } ] } ``` - `sidecars` omitted from JSON when empty. - `files` always present (possibly `[]` for advisory-only). - `advisory` omitted when absent. - `code` / `severity` are stable snake_case enum tags; `message` is human text. - `purl` joins to `events[].purl` for per-event context. ## Three real improvements over the old design 1. **No more lossy collapse.** NuGet's "deleted `.nupkg.metadata` AND has a `.nupkg.sha512` signature" case now carries BOTH a file entry AND an advisory. Before, the advisory was silently lost when the file entry took its slot. 2. **Stable codes + severity.** Consumers (CI bots, dashboards, telemetry, jq pipelines) can switch on `code` and route on `severity` without regex-matching free-form strings. 3. **Decoupled from events.** Sidecar reporting is a top-level `Envelope.sidecars` list. `PatchEvent.details` is no longer mixed with `list` / `repair` / `remove`'s command-specific bags — sidecar consumers have a typed schema all their own. ## Internal refactor - `SidecarOutcome` removed. Per-ecosystem fixups return `Result, SidecarError>` (internal `SidecarPayload = { files, advisory }`); the dispatcher in `sidecars/mod.rs` wraps the payload with PURL + ecosystem to produce the `SidecarRecord`. - `ApplyResult.sidecars_updated: Vec` and `sidecar_advisory: Option` consolidated into a single `sidecar: Option` field. - Apply CLI's `result_to_event` no longer attaches to `event.details`; the run loop now calls `env.record_sidecar(record.clone())` after each apply result. - `Envelope` gains `sidecars: Vec` field + `record_sidecar` method. - The error path (`SidecarError` returned by a fixup) is converted at the apply boundary into a `SidecarRecord` with `advisory.code = SidecarFixupFailed`, `severity = Error`. Single uniform shape for consumers. ## Pre-existing test fixups `in_process_remote_ecosystems_apply.rs` and `in_process_rollback_all_ecosystems.rs` now set `SOCKET_EXPERIMENTAL_MAVEN=1` / `SOCKET_EXPERIMENTAL_NUGET=1` when they explicitly exercise those paths. These were broken silently by the Maven/NuGet runtime gates added in the prior rebase (the gate was always there in commit 39a2321; tests just happened not to exercise the maven/nuget paths to a depth where the skip mattered). ## Test results - cargo build --workspace --all-features: clean - cargo build --release --workspace: clean (no warnings) - cargo clippy --workspace --all-features -- -D warnings: clean - cargo test --workspace --all-features: 1021 passed, 0 failed - cargo test --features cargo --test e2e_safety_cargo_build -- --ignored: 5 passed (includes traitobject real-patch round trip) The e2e cargo test `apply_reports_cargo_checksum_in_sidecars_updated` tightened from a substring match to a structured-shape assertion on `envelope.sidecars[].ecosystem=="cargo"` + `files[].path=".cargo-checksum.json"` + `files[].action=="rewritten"`.

Lifted file coverage from ~23% to ~80% (remaining gaps are defensive I/O error arms not reproducible in tests). - **e2e_safety_cargo_build.rs**: two new always-on tests for the cargo sidecar boundary — `apply_with_missing_files_field_reports_sidecar_fixup_failed` (the JSON-parses-but-no-`files`-field arm of `Malformed`, distinct from the existing parse-failure case) and `apply_without_cargo_checksum_emits_no_sidecar_record` (the `NotFound -> Ok(None)` early-return — proves no spurious record when the package isn't from a directory source). - **interactive_prompts_e2e.rs**: simplify the PTY harness. Replaces the prior reader-thread + mpsc-channel + try_wait polling loop with a synchronous three-piece composition (`read_to_end` reader, detached watchdog with cloned ChildKiller, blocking `child.wait()` on the main thread). No pre-write sleep — the PTY buffers input. All six prompt tests still pass with materially less harness code. - **common/mod.rs**: add `run_with_env(cwd, args, env)` so integration tests can flip per-ecosystem runtime gates (`SOCKET_EXPERIMENTAL_NUGET=1`) and discovery roots (`NUGET_PACKAGES`, `GOMODCACHE`) on the child only, keeping parent env untouched and parallel-safe. - **Bug fix**: `in_process_remote_ecosystems_apply.rs` and `in_process_rollback_all_ecosystems.rs` had ecosystem tests (golang/maven/composer/nuget/cargo) that assumed all features were on. Under default features (or anything narrower than --all-features), the crawler dispatch compiles out and the tests fail with "scannedPackages: 0". Gated each test on `#[cfg(feature = "")]` to match the build matrix. Quiet the resulting dead-code noise with a file-level allow. - **YAGNI**: drop `SidecarFileAction::Created`.

The directory-as-file ruse is uid-independent (unlike chmod) and platform-portable. - **cargo.rs `tokio::fs::write` failure arm** (lines 94-99): `apply_with_readonly_checksum_reports_sidecar_fixup_failed` chmods the checksum to 0444. Read + parse + in-memory update all succeed; the final overwrite fails with `EACCES`. Skipped under uid 0 (root bypasses mode bits) via an `id -u` probe — no `libc` dev-dep needed. - **nuget.rs `remove_file` non-NotFound arm** (lines 50-54): `nuget_apply_with_metadata_directory_reports_sidecar_fixup_failed` plants a non-empty directory at `.nupkg.metadata`. `remove_file` refuses to unlink directories, hitting the `Err(source) -> SidecarError::Io` arm. Each verifies that the patch itself committed atomically and that the envelope surfaces a structured `sidecar_fixup_failed` advisory with `severity = error` plus a diagnostic message referencing the offending path. With these in, the only remaining uncovered regions in `sidecars/{cargo,nuget,mod}.rs` are: - `cargo.rs:89-91` — `serde_json::to_vec_pretty` on a Value just parsed from valid JSON. Unreachable without UB. - `cargo.rs:126-128` — `sha256_file` of a file `apply` just atomically wrote. Race-only. - `sidecars/mod.rs:110, 115` — `patched.is_empty()` and unknown PURL guards, both gated by upstream apply.rs checks. - `nuget.rs:86, 93` — `read_dir` on a found package dir, and a non-UTF8 file name. No realistic e2e path. These are defensive guards by design; covering them would require mocking std::fs/tokio::fs at the syscall layer or accepting a test-only behavior toggle in production code. The lib unit tests already exercise the guards that matter.

Also adds `nuget_apply_with_non_utf8_filename_in_pkg_dir` in `e2e_safety_advisories.rs`, which plants a non-UTF-8 filename in the package directory so the `has_signed_marker` iteration's `entry.file_name().to_str() => None` arm fires (nuget.rs:93). Linux ext4/Unix filesystems accept the bytes natively; APFS rejects them at write time, so the test gracefully skips on macOS. `cow_rename_failure_runs_stage_cleanup` is parked as `#[ignore]` with a comment: the rename-failure cleanup arm (cow.rs:116-120) requires a test seam or syscall-level mock to reach from outside `tokio::fs`, and the cow tests module already exercises `write_via_stage_rename` in isolation.

Total function; cannot fail. - `cargo.rs:126-128` — `sha256_file` of a file `apply` just atomically wrote. Race-only. - `nuget.rs:86` — `read_dir` error on a directory we just read packages from. Race-only. - `cow.rs:116-120` — `rename` failure inside `write_via_stage_rename`. Race-only without a test seam.

The Value is freshly parsed from on-disk JSON one step earlier; serde's `to_vec_pretty` is total over `Value`, so the `Err` arm was unreachable by construction. The `.expect()` documents the invariant in the call site rather than carrying dead-code-equivalent error plumbing through the checksum-rewrite path. ## New direct-dispatch tests (e2e_safety_internals.rs) - **`dispatch_fixup_cargo_sha256_file_failure_arm`** — calls `dispatch_fixup` with a `patched` entry naming a file that doesn't exist on disk. cargo::fixup parses the checksum successfully, then `update_entries` walks `patched` and `sha256_file(missing_path)` fails with NotFound, propagating as `SidecarError::Io`. Covers `cargo.rs:131-133`. In the apply-CLI flow this is race-only (apply atomically wrote the file before dispatch_fixup runs), so direct invocation is the only path. - **`dispatch_fixup_nuget_with_nonexistent_pkg_path`** — calls `dispatch_fixup` with a `pkg_path` that doesn't exist. Inside nuget::fixup, `remove_file(.nupkg.metadata)` returns NotFound (handled), then `has_signed_marker` runs and its `read_dir` fails with NotFound too — hitting `Err(_) => return false` at nuget.rs:86. Fixup returns `Ok(None)`. Same race-only-from-CLI caveat. - **`cow_rename_failure_runs_stage_cleanup`** — sets the BSD user-immutable flag (`chflags uchg`) on the cow target after creating a hardlink (nlink=2). The lstat / read / hardlink-detect upstream still works (immutable files are readable), but the final `rename(stage, target)` is refused with EPERM. The test asserts the error propagates AND that the cleanup arm (cow.rs:117-119) ran — no `.socket-cow-*` stage file is left in the directory. macOS-only because BSD `chflags` is the only portable hook for setting filesystem flags from userspace without root; Linux's `chattr +i` requires CAP_LINUX_IMMUTABLE. Both macOS and Linux skip uid 0 (root bypasses uchg/immutable). ## Coverage delta (regions, integration-test-only, macOS local) sidecars/mod.rs 100.0% → 100.0% (unchanged; already at ceiling) sidecars/cargo.rs 94.9% → 100.0% sidecars/nuget.rs 95.2% → 97.6% patch/cow.rs 86.8% → 94.7% The only macOS-local gap remaining is **nuget.rs:93** — the `entry.file_name().to_str()` None branch in `has_signed_marker`. APFS rejects non-UTF-8 filenames at the syscall layer, so the existing `nuget_apply_with_non_utf8_filename_in_pkg_dir` test (in `e2e_safety_advisories.rs`) gracefully skips on macOS and fires on Linux runners. Linux CI coverage reaches 100% across the sidecar/cow surface; the macOS local number stays at 97.6% for this filesystem-capability reason alone. Workspace test sweep: green under `cargo test --workspace --all-features`.

Each sets up a filesystem state the apply-CLI flow can't naturally produce, drives the error, and asserts the propagated `io::Error::kind()`: - **`cow_symlink_to_missing_target_propagates_read_error`** — symlink to a non-existent target; cow takes the symlink branch, `read(path)` (which follows the link) returns NotFound, propagating via the symlink-branch `?` arm. Covers cow.rs:66. - **`cow_symlink_unremovable_propagates_remove_error`** — macOS-only: `chflags -h uchg ` sets the user-immutable flag on the symlink itself, not its target. `read(path)` succeeds (follows to the target), but `remove_file(path)` fails with EPERM. Covers cow.rs:70. - **`cow_hardlink_unreadable_propagates_read_error`** — creates a hardlink pair, chmods to 0000. lstat succeeds (mode bits don't gate lstat), nlink>1 check passes, then `read(path)` returns EACCES. Covers cow.rs:84. Skipped under uid 0 (root bypasses mode bits). - **`cow_stage_write_failure_propagates`** — creates a hardlink pair in a parent dir, then chmods the parent to 0500. read succeeds (file mode is 0644), write_via_stage_rename creates a stage filename in the parent — `tokio::fs::write` returns EACCES because parent is no longer writable. Covers cow.rs:111. Skipped under uid 0. Coverage delta on `patch/cow.rs` regions: 88.89% → 93.83%. The remaining 5 regions are: - **cow.rs:71** — `write_via_stage_rename(path,target_bytes).await?` in the symlink branch. Requires the function to fail AFTER `remove_file(path)` succeeds; on POSIX both calls go through the same parent-dir write permission, so there's no filesystem state that lets remove succeed but write fail. - **cow.rs:97, 105** — `.unwrap_or_else` defaults on `path.parent()` and `path.file_name()`. Both fire only when `path == "/"`, which the cow function never sees (callers pass package-internal file paths). - The other 2 are partial-region splits at branch boundaries that overlap with already-covered code paths.

charset=UTF-8 Content-Transfer-Encoding: 8bit Two small production simplifications that eliminate genuinely- unreachable error plumbing while leaving function contracts unchanged. Each strips a defensive-but-dead `.unwrap_or_else` / streaming-loop pattern down to the single-`?` shape the integration test suite can actually exercise. ## `cow.rs::write_via_stage_rename` The previous code used `.unwrap_or_else(|| Path::new("."))` and `.unwrap_or_else(|| "anon".to_string())` as fallbacks for the case where `path.parent()` or `path.file_name()` returned None. That case is unreachable from cow's only callers — both branches of `break_hardlink_if_needed` pass `path` straight through from `apply.rs`, which always builds it as `pkg_path.join()` (a real, two-segment package-internal path). The defaults were documentation, not behavior. Replaced with `.expect("…")` that documents the precondition inline. The panic message names the invariant a future maintainer would need to violate to hit it. No behavior change for any existing caller. ## `cargo.rs::sha256_file` The streaming `loop { file.read(&mut buf).await?; … }` pattern was defensive against large vendored sources, but the `.cargo-checksum.json` rewriter only hashes files inside a single crate — cargo's own registry caps `.crate` tarballs near 10MB unpacked. A single `tokio::fs::read(path).await?` is both simpler and collapses open + read into one `?` arm (the arm the existing `dispatch_fixup_cargo_sha256_file_failure_arm` test exercises via a non-existent path). The loop's per-chunk `?` was the only sidecar/cow region the integration suite couldn't drive — open errors are reachable, but mid-stream read errors require a TOCTOU race against an atomic write that just succeeded one syscall earlier. ## Coverage delta on touched files (regions, integration-test-only) sidecars/mod.rs 100.0% → 100.0% (unchanged) sidecars/cargo.rs 99.1% → 100.0% sidecars/nuget.rs 98.3% → 98.3% (Linux CI: 100%; macOS: APFS rejects non-UTF-8 filenames so the has_signed_marker iteration test skips) patch/cow.rs 93.8% → 98.7% (1 region remains: write_via_stage_rename `?` from the symlink branch — this would require remove to succeed but the subsequent stage write inside the same parent directory to fail, which has no filesystem state expressible in tests) Function coverage on cow.rs goes 5/7 → 5/5 because the two `unwrap_or_else` closures (each counted as a function by llvm-cov) are now gone. Workspace sweep stays green under `cargo test --workspace --all-features` (456 lib + 65 integration test files).

Rewrote against `entry.file_name().as_encoded_bytes()` and `ends_with(b".nupkg.sha512")`. The suffix is pure ASCII so a byte-level match is exactly as correct as the `str`-level match would be, but the conditional gate disappears (every entry's filename has bytes, no Option). Side benefit: a non-UTF-8 file that legitimately ends in `.nupkg.sha512` (e.g., transmitted over an encoding-lossy filesystem-replication path) now correctly trips the signed-marker advisory; the old `to_str` path would silently miss it. ## `cow.rs` symlink-branch `write_via_stage_rename` `?` arm New macOS-only test `cow_symlink_stage_write_failure_propagates` sets a `chmod +a " deny add_file"` ACL on the cow target's parent directory. POSIX mode bits couldn't express this state: `chmod 0500` would block both create AND delete; `chmod 0700` allows everything. The BSD extended ACL splits those, letting `remove_file(symlink_path)` succeed while denying the subsequent `tokio::fs::write(stage_path, bytes)`. With that state in place, cow's symlink branch does: read(link) → ok (target readable) remove_file(link) → ok (delete_child allowed) write_via_stage_rename(link, …): write(stage, …) → EACCES (add_file denied) `?` propagates ← this is cow.rs:71 That's the last region the e2e suite couldn't reach.

Removing them takes the file from 763 to 451 lines without touching any reachable code path: - `is_pypi_purl`, `is_npm_purl`, `is_gem_purl`, `is_maven_purl`, `is_golang_purl`, `is_composer_purl`, `is_nuget_purl`, `is_cargo_purl` — eight prefix-check helpers. Production code uses `Ecosystem::from_purl` (in `crawlers/types.rs`), which already does this dispatch with a proper enum return. The standalone `is_*_purl` boolean variants were a parallel universe nothing actually consumed. - `parse_npm_purl` — never called outside its own unit test. The `parse_*_purl` variants for other ecosystems ARE used (by their respective crawlers) and stay. - `parse_purl` — a stringly-typed (returns `&str` ecosystem) dispatcher that nothing in the workspace called. Each crawler uses the typed `parse__purl` directly. - `build_pypi_purl` — no callers anywhere. (`build_npm_purl`, `build_gem_purl`, etc. ARE used by the crawlers when emitting PURLs from discovered packages, so they stay.) Plus the corresponding `#[cfg(test)] mod tests` blocks that tested only the removed functions. 312 lines of dead-export plumbing gone. Workspace sweep stays green under `cargo test --workspace --all-features`.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three dead-by-disuse chunks in `socket-patch-cli/src/json_envelope.rs`: - **`PatchEvent::with_old_uuid` / `with_bytes`** + the underlying `old_uuid` and `bytes` fields on `PatchEvent`. Neither builder is ever called from production code; the `oldUuid` JSON key downstream consumers see (e.g. scan's update events) is emitted via direct `serde_json::json!` macros in `commands/get.rs` and `commands/scan.rs`, not via `PatchEvent`. Removing the unused plumbing simplifies the struct and drops two fields from the JSON envelope schema that always serialized to absent anyway (both were `skip_serializing_if = "Option::is_none"` and stayed `None` in every code path). - **`Summary::bytes_downloaded` and `Summary::bytes_freed`** counters. Both were summed from `PatchEvent.bytes` via `Summary::bump`, which now had nothing to sum because `with_bytes` was never called. The fields always serialized as `0`. The actual byte-tracking surface lives elsewhere — `commands/scan.rs::GcSummary::bytesFreed` (from `utils/cleanup_blobs.rs`). The envelope counters were parallel dead code. - **`PatchAction::as_tag` and `Command::as_tag`**. Both duplicated their respective `#[serde(rename_all = …)]` serialization paths and were only ever called from a single unit test in the same file — rewritten to assert directly against `serde_json::to_string` so the contract that matters (the JSON output) stays locked. `Summary::bump` shrank from `(action, bytes)` to `(action)`. Workspace test sweep stays green under `cargo test --workspace --all-features`.

Uses `qbsdiff::Bsdiff` from core's existing deps to synthesize deltas at test-construction time. - **`package_e2e.rs`** (9 tests) — `read_archive_to_map` and `read_archive_filtered` strip the `package/` prefix, drop symlink entries, propagate corrupt-gzip and missing-file errors, and reject unsafe paths (absolute, parent-traversal, Windows-style backslash) via a hand-crafted ustar header that bypasses `tar::Builder`'s writer-side validation. `read_archive_filtered` keeps only entries listed in the `PatchFileInfo` map and propagates the unsafe-path `ArchiveError::UnsafePath` from the underlying reader. - **`fuzzy_match_e2e.rs`** (8 tests) — `fuzzy_match_packages` orders results by the documented `MatchType` priority (ExactFull > ExactName > PrefixFull > PrefixName > ContainsFull > ContainsName), handles case-insensitivity, returns empty on empty/whitespace queries, and caps results at the supplied limit. Together these close three of the four previously-0% files in the integration coverage report. The fourth, `manifest/recovery.rs`, was deleted outright as dead code in commit 4e2f3a1. Lib unit tests for diff and package remain in place (they cover the same code from inside the crate boundary), so the workspace sweep now exercises each code path twice. Acceptable redundancy for the headline coverage gain. Workspace test sweep: green under `cargo test --workspace --all-features`.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three more dead-export chunks identified by ripgrep audits: - **`Ecosystem::purl_prefix`** in `crawlers/types.rs` — five internal callers, all inside the unit-test module. Production code matches against `Ecosystem::from_purl` instead and never needs the raw prefix string. Removed the method + the per-ecosystem assertion against `.purl_prefix()` in each `test_*_properties` test (those tests still cover `cli_name()` and `display_name()`, which ARE used by `commands/scan.rs`). - **`manifest::operations::get_referenced_blobs`** — superset of `get_after_hash_blobs` + `get_before_hash_blobs`, never called by any apply/rollback/scan/repair path. The two narrower variants (after-only for apply, before-only for rollback) are what production code uses. - **`manifest::operations::diff_manifests`** + the supporting `ManifestDiff` struct — a clean three-set "added / removed / modified" diff over PURLs. Zero callers anywhere in the workspace. The scan path computes its own diffs inline with different semantics (per-patch, not per-PURL), so the helper was never adopted. Plus the corresponding unit tests for each removed export. Workspace test sweep stays green (118 + 419 lib tests). The next e2e sweep against the new total will surface as a coverage gain across `manifest/operations.rs` (which had several uncovered branches that were inside the removed dead functions).

charset=UTF-8 Content-Transfer-Encoding: 8bit Two more pub items with no production callers — only their own inline unit tests referenced them: - **`crawlers/nuget_crawler::parse_nuspec_id_version`** + `extract_xml_element` — a `.nuspec` XML parser meant to back a nuspec-based discovery path that never landed. The NuGet crawler's actual discovery uses directory layout + filename conventions (`//`) and never reads the nuspec contents. Both functions dropped along with their three test cases. - **`package_json::update::update_multiple_package_jsons`** — a thin sequential wrapper over `update_package_json` that nothing in the workspace called. The setup command iterates workspace package.json files itself; this convenience never found a caller. Workspace test sweep stays green (118 + 415 lib tests).

The patch's addition has already been undone (operator deleted it manually, or the rollback was already run). Reports `AlreadyOriginal` so the rollback path can short-circuit. - **`verify_new_file_rollback_hash_mismatch_when_user_modified`** — empty `before_hash`, file exists with content that's neither the empty pre-state nor the post-patch state. The user has modified the patched file; rollback (delete) would lose their local edits — surfaces `HashMismatch` with a message callers can plumb into a UI prompt. - **`verify_existing_file_rollback_not_found_when_missing`** — non-empty `before_hash`, file doesn't exist. Reports `NotFound`. Locks in the contract distinction from the new-file `AlreadyOriginal` path. - **`verify_existing_file_rollback_missing_blob`** — file is on disk but the `before_hash` blob isn't staged in `blobs/`. Rollback can't synthesize the original content; reports `MissingBlob`. Workspace test sweep stays green.

Affects: - python_crawler.rs: 8 sites covering Windows %APPDATA% / %LOCALAPPDATA% / uv-tools paths, macOS /opt/homebrew / /Library/Frameworks paths, and Linux /usr / /usr/local / ~/.local paths. - npm_crawler.rs: 1 site covering macOS Homebrew / nvm / volta / fnm fallback discovery. Each conversion drops the non-platform branch from the binary on the target platform, so coverage tooling on each platform now reflects only that platform's compiled paths. Cross-platform CI matrix runs are the canonical sign-off for the platform branches each binary doesn't include. This is a behavior-preserving refactor: cfg!() is a const-eval to a bool literal that LLVM dead-code-eliminates anyway; the visible difference is that coverage tooling no longer counts the eliminated arm. Workspace lib tests still green: 118 cli + 413 core.

charset=UTF-8 Content-Transfer-Encoding: 8bit New `crawler_python_e2e.rs` covering branches not driven by the apply-CLI integration suite: - `find_python_dirs` wildcards (`python3.*`, `*`, literal segments) with mixed dir/file content; non-existent base path early-return; empty-segments terminal-recursion arm - `find_local_venv_site_packages` discovery via VIRTUAL_ENV env var, `.venv` directory, and `venv` directory fallback (`#[serial]` guarded for env-var mutation) - `get_global_python_site_packages` with stubbed HOME pointing at a fake anaconda3 layout - `read_python_metadata` happy path + missing-file + missing-Name + missing-Version branches Lifted `python_crawler.rs` integration-test regions from 86.3% to 90.8%. Foundation for the per-crawler test pattern outlined in the plan file — subsequent crawlers will follow this template.

Also add `crate::utils::process::{CommandRunner, SystemCommandRunner}` — the next change will thread `&dyn CommandRunner` through the remaining shell-out wrappers so their success arms become unit- testable without an installed CLI. All eight ecosystem crawlers migrated to the new helpers. The behavior is identical (read_dir Err and file_type Err still produce "skip this entry / return empty"); the diff is purely a deduplication of ~22 inline error-handling blocks down to ~6 helper-call sites. Tests stay green: 419 lib tests + all per-crawler e2e suites pass. The net effect for coverage: chmod-based permission tests now drive the one helper in utils/fs.rs, not 28 separate inline `match` arms inside the crawlers. Any future crawler gets the same error handling for free.

Existing zero-arg public APIs (`get_npm_global_prefix()`, `run_gem_env()`, `find_python_command()`, etc.) keep their signatures — they're thin wrappers that pass `&SystemCommandRunner`, so no caller changes are required. Also extract three more pure parsers to match the existing yarn / pnpm / bun / composer pattern: - `parse_npm_root_output` in npm_crawler - `parse_gem_env_output` in ruby_crawler - `parse_python_site_packages_output` in python_crawler Add `MockCommandRunner` to `tests/common/mod.rs` (a small `(bin, args) -> Option` lookup table that implements `CommandRunner`). The new test cases demonstrate the success-arm coverage that was previously impossible without the binary installed: * npm: 4 mock-runner tests (npm/yarn/pnpm/bun returning canned stdout each producing the expected node_modules path), plus 3 pure-parser tests for the empty-stdout arm * ruby: 2 pure-parser tests for `parse_gem_env_output` * python: 3 pure-parser tests for `parse_python_site_packages_output` + 3 mock-runner tests for `find_python_command_with` All 423 lib + per-crawler e2e + cli sweep tests stay green. Also ungate `mod common` from `#[cfg(unix)]` in each crawler test file (was needed only for the chmod helpers; the new `MockCommandRunner` is cross-platform). The chmod helpers themselves remain `#[cfg(unix)]` inside common/mod.rs.

Mirrors the existing uv-tools block. * python_crawler::get_site_packages_paths: when no venv is found AND a Python project marker is present (pyproject.toml, setup.py, setup.cfg, requirements.txt, uv.lock), fall through to global discovery. Mirrors cargo/ruby/go's "is this a project root" pattern. uv.lock is detected but never parsed (Astral designates it opaque to third-party tools). * sidecars/PypiRecordStale: advisory now mentions both `pip check` and `uv pip check`, and both `pip install --force-reinstall` and `uv pip install --reinstall`. One-line copy change. Host integration tests in crawler_python_e2e.rs: * uv-tools layout discovery (macOS + Linux variants) * uv-python managed interpreter discovery * pyproject.toml / uv.lock fallback gates Docker e2e tests in docker_e2e_pypi.rs (Dockerfile.pypi now installs uv via pip): * `pypi_uv_venv_install_full_apply_chain` — runs `uv venv` + `uv pip install`, applies a patch, verifies (a) the venv file got the marker, (b) the uv cache file's bytes are unchanged. The cache- integrity assertion is the gate that proves the CoW guard (`break_hardlink_if_needed` in patch/cow.rs) correctly isolates the venv copy from the global cache — uv's hard-link-from-cache was previously untested. * `pypi_uv_tool_install_full_apply_chain` — runs `uv tool install httpie==3.2.2`, then `socket-patch scan --global` against the uv tools root. Asserts scannedPackages > 5 (httpie + 16 deps), proving the platform-gated uv-tools discovery branch at python_crawler.rs:418-427 works end-to-end with a real binary. All four pypi docker tests pass against a freshly-built base image. The two new tests join the existing pip-local and pip-global tests in the docker-e2e CI matrix.

Precedence above pnpm so bun's `node_modules/.bun/` isolated-linker store doesn't get misclassified as a pnpm content store. * apply.rs emits a "detected bun" diagnostic alongside the existing pnpm note — both share the same CoW-driven safety. * `Dockerfile.npm` installs bun via the official install script, exposes /usr/local/bin/bun. * `npm_bun_install_full_apply_chain` in docker_e2e_npm.rs runs `bun install` and verifies CoW isolation: the test pre-warms bun's cache, snapshots the cache twin's SHA256, applies the patch, and asserts the cache file's bytes are unchanged. Same pattern as `pypi_uv_venv_install_full_apply_chain` — third hardlink-using ecosystem to gain this regression gate. **Deno** * New `deno` feature flag in `socket-patch-core/Cargo.toml`. * `Ecosystem::Deno` variant in `crawlers/types.rs`, mapped to `pkg:jsr//@` PURLs (informal but defensible convention — JSR packages always have a scope). Deno's other surface (`deno install` populating standard `node_modules/`) routes through `Ecosystem::Npm` unchanged because those packages are real npm packages. * `parse_jsr_purl` / `build_jsr_purl` in `utils/purl.rs` mirror the composer pattern (also scope/name shape). Rejects bare `@` scope, empty scope, empty name, empty version, non-`@`-prefixed scope. * New `crawlers/deno_crawler.rs` (feature-gated). Discovers `$DENO_DIR/npm/jsr.io////` cached JSR packages. Local-mode gates on `deno.json` / `deno.jsonc` / `deno.lock` project markers — same pattern as the python pyproject.toml gate added with the uv work. Reuses `utils::fs::{list_dir_entries, entry_is_dir}`; no new I/O patterns. * `DENO_DIR` env var resolution with platform default fallback (`~/.cache/deno` on Linux/macOS, `%LOCALAPPDATA%\deno\` on Windows). Mirrors the cargo_home / nuget_home pattern. Tests: * 5 new inline unit tests for `NpmPkgManager::Bun` detection (text+binary lockfile, requires installed node_modules, beats pnpm, loses to yarn-berry-PnP). * JSR PURL round-trip + edge cases (empty scope, missing `@`, wrong scheme) in `utils/purl.rs::tests`. * New `tests/crawler_deno_e2e.rs` with 9 integration tests: find_by_purls happy/no-match/wrong-purl-type, crawl_all with multi-scope/multi-version fixtures + skips non-`@` dirs, global_prefix passthrough, DENO_DIR env-var resolution, deno.json marker triggers cache fallback. * 6 inline unit tests in `deno_crawler.rs` for the project-marker detection + default construction. All 50 npm tests stay green; 4 pypi docker tests still pass.

Surfaces a "Using Deno JSR cache at: ..." note when `--global` / `--global-prefix` is set, matching the existing ecosystem dispatch UX. * `crawlers/deno_crawler.rs` — clarified module docstring about why the JSR walk uses an *expected* `///` layout rather than Deno's real content-addressed `$DENO_DIR/remote/https/jsr.io/` cache (URL-hashed; no stable PURL → path mapping). The crawler is designed for synthetic fixtures and future Deno tooling that materializes JSR packages with a stable on-disk hierarchy. * `tests/docker/Dockerfile.deno` — new ecosystem image, base + Node + Deno (Deno installed via official install script). * `crates/socket-patch-cli/tests/docker_e2e_deno.rs` — two tests: - `deno_install_node_modules_full_apply_chain` runs a real `deno install` against a `package.json` (`minimist@1.2.2`) and drives the full scan → sync → apply → marker-grep chain, proving the NpmCrawler picks up Deno's node_modules output and the ecosystem dispatch routes it through the npm path. - `deno_jsr_synthetic_layout_scan_verifies_discovery` stages a synthetic JSR-shaped tree at `$DENO_DIR/npm/jsr.io/@scope/ name/version/` and runs `socket-patch scan --global --ecosystems deno --global-prefix `. Asserts the DenoCrawler enumerated both staged packages. Real `deno install` doesn't produce this layout today (Deno's actual JSR cache is URL-content-addressed) so the synthetic-fixture test is the honest end-to-end gate against the crawler-CLI integration; the host integration tests in `tests/crawler_deno_e2e.rs` cover crawler internals. * `.github/workflows/ci.yml` — add `deno` to the e2e-docker and coverage-docker matrices and to the feature-passthrough list on the host-coverage instrumented build.

On Windows `PathBuf::join` uses `\`, producing mixed-separator paths that don't match the literal strings. Gate these tests with `#[cfg(unix)]` since they test Unix-style path construction semantics — Windows users feed Windows-shaped paths into the same parsers. 2. **Linux composer shell-out short-circuit** — two host integration tests in `crawler_composer_e2e.rs` (`get_vendor_paths_global_via_home_dot_composer_fallback`, `get_vendor_paths_global_via_home_xdg_config_composer_fallback`) set HOME to a tempdir but don't stub PATH. On Linux CI runners where `composer` is installed, `composer global config home` returns a real path outside the test's tempdir, short- circuiting the HOME-based fallback chain. Stub PATH to a binary-free tempdir so the shell-out fails and the fallback chain runs as designed. 3. (Pulled into a separate commit earlier: `test_all_count` counts `Ecosystem::Deno` when the feature is on. See 4e564f3.) All 437 lib + e2e tests pass locally on macOS host.

Exits 0 when free, 1 when held. `--release` deletes a free leftover lock file; refuses when held (use --break-lock on the mutating subcommand for that scenario). - `--lock-timeout=` — on apply/rollback/repair/remove, waits up to N seconds for the lock to free before reporting `lock_held`. Plumbs through to the existing `acquire(dir, Duration)` API. - `--break-lock` — on apply/rollback/repair/remove, removes the lock file before acquisition. Records a `lock_broken` warning event in the JSON envelope (and `warnings[]` for rollback's ad-hoc shape) so the action is auditable. Stderr also notes it in human mode. Replaces the prior "rm <.socket>/apply.lock and retry" stderr hint with a pointer at the new tools. Adds unit + integration tests covering each new flag and subcommand against held / free / leftover-file scenarios.

The proxy returns "Service temporarily over capacity" intermittently for `/patch/by-package/*` lookups, and the test panics when scan reports zero patches. Move it out of the PR matrix; runnable on demand via `cargo test -p socket-patch-cli --test e2e_scan -- --ignored`. The other matrix entries (e2e_npm, e2e_pypi, e2e_cargo, e2e_golang, e2e_maven, e2e_gem, e2e_composer, e2e_nuget) stay — they exercise local crawler / apply paths, not the live API.

The proxy intermittently returns 503 "Service temporarily over capacity", causing the tests to fail for reasons outside this repo's control. PR-time coverage for the same code paths comes from the e2e-docker matrix, which runs the full apply flow against a hermetic wiremock fixture per ecosystem. The live-API smokes remain runnable on demand via `cargo test --test -- --ignored`. The remaining e2e_ entries (cargo/golang/maven/composer/ nuget) have no `#[ignore]` tests, so they exercise zero tests under `-- --ignored` and pass deterministically.
