Close the last 31 clippy findings so the newly-ungated -D warnings gate passes - #147
Conversation
…te passes `main` went red the moment #146 turned the suite on: `Clippy (deny warnings)` failed. Measured with the workspace command rather than guessed — 31 findings across 10 files, and the first one was mine. ## The blocker was a miss in my own #145 sweep error: redundant reference in `assert!` argument --> crates/pampa/tests/integration/test_treesitter_coverage.rs:469:9 #145's commit message says it fixed this exact lint at "19 sites", including line 73 of this very file. It missed line 469 in the same file. The gate that #146 turned on caught it — which is the gate doing its job on its first run. ## The other 30, and why almost none of them are deleted 27 are dead_code in cockpit-server; 3 are real quality findings. Deleting unwired surface is a product decision, so the code is preserved and annotated instead. Two agents' findings make that the right call rather than the timid one: - The five `resolve_garmin_*` functions and `mime_from_path` DO have call sites — inside `#[cfg(feature = "embed-cockpit")]`. Feature-gating artifact, not abandoned code. - Every unread field in openai.rs is OpenAI wire schema: the structs derive Deserialize and the fields must exist for client payloads to parse. A field that exists to satisfy an external protocol is not dead weight. ## expect vs allow is measured, not stylistic The first pass used `#[expect(dead_code)]` throughout, for its self-cleaning property: it warns if the item later becomes used. The central gate then reported 18 x "this lint expectation is unfulfilled". The cause is structural. Those 18 items ARE used — under `#[cfg(test)]` or a feature gate. `--all-targets` compiles such a file more than once, so the item is dead in one compilation and alive in another, and no single `expect` can hold in both. Those 18 became `#[allow]`, each reason recording why. The 13 that are dead in every target keep `expect`, so it still self-cleans where it can. `default_distance_table`, `jsonrpc` and `mime_from_path` sit in the same files as items that flipped, and correctly did not flip. ## The three real fixes - osm_features: `assert!(GEOMETRY_CITY_BUDGET > GEOMETRY_OVERVIEW_BUDGET)` in a test compared two `const`s, so it could never fail at run time — the vacuous assertion this repo's own falsifiability rule names, sitting feet from a comment reading "Anti-vacuity test". Promoted to `const _: () = assert!(...)` at module scope: reordering the budgets now fails the BUILD, not one test. Strictly stronger, and the test's two `assert_eq!` calls are untouched. - osm_features: `decode_tile_bin`'s nested-tuple return type factored into `Point` / `DecodedShape` / `DecodedTile`. Signature only; body byte-identical. - osint_gotham: `BasinPlan` was private while `pub fn osint_node_rows` exposes it. Widened to `pub(crate)` to match the function's real reachability — not to `pub`. ## Verification cargo clippy --workspace --all-targets --profile ci -- -D warnings 0 warnings, 0 errors cargo fmt --all -- --check clean Both are CI's own commands. Every edit was written by hand via scoped agents on disjoint files; `clippy --fix` was not used, per the same reasoning as #145 — its unused_* machinery deletes code the author may still want, which is exactly the decision being deferred here. The full test suite was NOT run locally: linking the workspace's test binaries exhausts this sandbox's disk (it hit 1.3 GB free and was stopped). What that does and does not cover: `clippy --all-targets` compiles every test target, so everything type-checks; the one change touching a test body is the const-assert promotion, and a false `const _` assert is a compile error, so its invariant is proven by the build. The remaining edits are annotations, a visibility widening, type aliases, and a `{:?}` argument where `Debug for &T` forwards to `T`. CI runs the tests.

…pit build CodeRabbit flagged `mime_from_path`'s `#[expect(dead_code)]` as unfulfilled under `--features embed-cockpit`. It was right, and chasing it found something bigger sitting underneath: with that feature enabled, cockpit-server did not compile at all. ## The regression, and it is mine `25f4b940` (the #145 lint sweep) removed `use axum::http::{StatusCode, header}` down to `StatusCode` alone. `header::CONTENT_TYPE` is used at five sites — 614, 670, 712, 745, 757 — and every one of them is inside a `#[cfg(feature = "embed-cockpit")]` block. In a default build those blocks are compiled out, so the import genuinely looks unused and clippy said so. I removed it. With the feature on: error[E0433]: cannot find module or crate `header` x5 CI never enables `embed-cockpit`, so nothing caught it. The Dockerfile does (`cargo build -p cockpit-server --features embed-cockpit`), so this has been broken on the production build path since #145 merged. Fix: restore the import gated to match its usage, rather than merging it back into the braced form that caused the problem — a single `use` cannot be half-gated: use axum::http::StatusCode; // both configurations #[cfg(feature = "embed-cockpit")] use axum::http::header; // only where it is used ## The lint finding that led here `mime_from_path` keeps its annotation but as `#[allow]`, not `#[expect]`: with the feature enabled `static_handler` calls it, so no expectation holds in every configuration. Same structural rule this PR already applied to 18 other items — I simply failed to apply it here, because my gate only ever ran the default feature set. That was the real hole: the classification was sound, the measurement behind it was too narrow. main.rs now carries 1 `expect` (the `jsonrpc` wire field, dead in every configuration) and 6 `allow`. ## Verification — both configurations this time default, workspace, -D warnings 0 findings --features embed-cockpit, cockpit-server 0 errors cargo fmt --all -- --check clean The feature build needs `cockpit/dist` to exist for `include_dir!`; a stub was created locally to verify and removed afterwards (it is gitignored either way). ## Deliberately NOT fixed here The feature build still reports 6 style warnings — 3 `needless_return`, 3 `collapsible_if`, at main.rs 629/668/678/710/720/755 — in code that until this commit could not be compiled, so nothing had ever linted it. They block neither CI (which does not enable the feature) nor `cargo build`. Left alone because the `needless_return` fix turns on cfg-dependent tail-expression semantics: those `return`s are only redundant because the paired `cfg(not(...))` block disappears, and getting that wrong would re-break the build path this commit repairs. Worth its own change, not a drive-by on a lint PR. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01AGVLyRZNEKKBSfBDJfbY3V

macOS CI failed to compile cockpit-server:
error[E0425]: cannot find function `posix_fadvise` in crate `libc`
error[E0425]: cannot find value `POSIX_FADV_DONTNEED` in crate `libc`
error: could not compile `cockpit-server` (bin "q2-cockpit")
`advise_dontneed` in osm_slab_hydrate.rs was gated `#[cfg(unix)]` with a
`#[cfg(not(unix))]` no-op beside it. `posix_fadvise` is a Linux/Android
extension, not POSIX-universal — Apple's libc does not declare it — so
`cfg(unix)` reads as "has fadvise" and is not. The function's own doc
comment stated the wrong premise ("No portable equivalent exists ... on
non-Unix targets"), which is what made the gate look correct.
This is the SECOND instance of this exact defect today. The first was in
lance-graph (AdaWorldAPI/lance-graph#1208, merged); q2 carries its own
independent copy in this file. Fixing lance-graph's did not fix this one,
and the macOS job moved from failing in `lance-graph-hydrate` to failing
here — same error, different crate.
Fix (identical to #1208): gate both arms on the OS that actually has the
call, and record the rule in the doc comment so the gate is not re-widened
by intuition.
Both arms still bump the `#[cfg(test)]` FADVISE_ATTEMPTED counter, so the
reachability test is unaffected on either platform.
Verification — red-then-green on the REAL CI target (macos-latest is Apple
Silicon), compiling the gate pair against the real `libc` crate:
new gate, aarch64-apple-darwin compiles OK
new gate, x86_64-unknown-linux-gnu compiles OK
OLD cfg(unix) control, aarch64-darwin reproduces both E0425s exactly
Plus a two-sided `#![no_std]` cfg probe on the pinned 1.98.1 toolchain:
x86_64/aarch64-apple-darwin exclude the Linux arm; x86_64-unknown-linux-gnu
selects it. `cargo fmt -p cockpit-server -- --check` clean.
NOT verified here: a full `cargo check -p cockpit-server` in either
configuration. This sandbox cannot build that dependency tree (lance +
datafusion + deno exhaust the disk), and cross-compiling it for darwin
additionally needs a C toolchain for `ring`. The change is three cfg
attributes and a doc comment, and the gate pair itself is compile-proven
above against real libc on both targets.

Scope note
This is a cockpit-server compile fix on a PR about cockpit-server lint findings, and it is what stands between this PR and a green macOS job — not a widening. It is the same change already reviewed and merged as lance-graph#1208.
Where #147 stands now
- macOS — should now compile. This was blocker 2 of 2 on that platform.
- Linux — still blocked on
rusty_v8(cargo nextest run), unchanged and unrelated. Root cause and a proposed patch are in the previous comment; it needs its owntest-suite.ymlPR.

…gets
macOS CI, on the previous commit's head:
error: function `parse_cgroup_current` is never used
error: function `parse_cgroup_max` is never used
error: could not compile `cockpit-server` (bin "q2-cockpit")
NOT caused by that commit — revealed by it. Both functions are ungated,
and their only non-test callers sit inside `read_cgroup_memory`'s
`#[cfg(target_os = "linux")]` arm, so on macOS they have been dead since
they were written. The crate previously died at the `posix_fadvise`
E0425 before dead-code analysis ever ran, so nothing reported it.
That is the same peel-back this whole PR arc has been: each fix lets the
build reach the next thing that was never checked.
The fix is the rule this PR already established 18 times: `#[allow]`, not
`#[expect]`, because the item is alive in one compilation and dead in
another — here across TARGETS rather than across features, but the same
reason applies. `expect` would fire "unfulfilled" on Linux, where both
functions genuinely are used. Each carries a reason naming the asymmetry.
Nothing is deleted: these parse cgroup v2 memory accounting and are
exercised by six tests in this module on every platform.
Swept for the same defect rather than fixing only what CI named. This
crate has exactly three platform gates:
osm_artifact_manager.rs read_cgroup_memory cfg(target_os = "linux")
osm_lance.rs advise_dontneed cfg(unix)
osm_slab_hydrate.rs advise_dontneed cfg(any(linux, android))
The latter two define BOTH arms, so nothing becomes dead through them.
`read_cgroup_memory` itself and both `CgroupMemory` fields are read
ungated from main.rs, so they stay alive on macOS; the two parsers were
the only casualties.
`osm_lance.rs`'s `cfg(unix)` is CORRECT and deliberately left alone: it
calls `memmap2::Mmap::advise`, i.e. `madvise`, which is genuinely
POSIX-wide and present on macOS. The naming is backwards from intuition
— `posix_fadvise` is the Linux-only one despite its name; `madvise` is
the portable one. Narrowing that gate would have been a regression.
Outside cockpit-server every platform gate in the workspace is
`cfg(unix)`, which is TRUE on macOS, so none of them can produce
macOS-only dead code.
Verification: `cargo fmt -p cockpit-server -- --check` clean. A full
`cargo check -p cockpit-server` is not possible in this sandbox (lance +
datafusion + deno exhaust the disk; darwin cross additionally needs a C
toolchain for `ring`), and `allow(dead_code)` cannot itself fail a build
— it can only suppress. The risk this carries is that it suppresses too
little, which CI reports, not too much.

This makes the gate pass; it does not answer the keep-or-delete question. Every suppression is a reversible annotation carrying its reason, so the decision stays available. Two items worth a look when you take it:
ErrorResp/ErrorObjare "never constructed" — a different signal from "never read".
