Enable strict clippy with documented allow-list and defensive-coding pass#257
Conversation
Turns on `pedantic` (warn) and `restriction` (deny) workspace-wide and adds
`[lints] workspace = true` to every crate so the policy actually applies.
Captures a baseline allow-list in `Cargo.toml`, organized by category
(Documentation, Style/formatting, Defensive coding, API design, Imports/paths,
Output/diagnostics, Tests, Attributes) with per-lint counts and rationales —
each entry is a TODO unless explicitly marked intentional.
Defensive-coding pass:
- New `clippy.toml` with `allow-{unwrap,expect,panic,indexing-slicing}-in-tests`
so test code keeps its conventional idioms; production code is denied.
- Production unwraps factored out: `current_dir()`/`init_logger()` now
propagate via `?`; `writeln!` to a `String` rewritten as `push_str(&format!)`
so there's no `Result` to discard; bundled-template registration and other
genuine compile-time invariants use `.expect("...")` as documented assertions.
- Other small wins: `inefficient_to_string` fixed, `match_same_arms` collapsed,
`manual_assert` swapped, `cast_lossless`+truncation replaced with bound-checked
`u16::try_from` in adapter-axum CLI, `unreachable!()` in `#[action]` macro
replaced with a proper `syn::Error::compile_error`.
Lints kept allowed in the workspace are annotated with `(intentional)` where
they conflict with idiomatic Rust (`implicit_return`, `question_mark_used`,
`pattern_type_mismatch`, `default_numeric_fallback`, `arithmetic_side_effects`,
`as_conversions`, `string_slice`) or have no per-test config option
(`assertions_on_result_states`).
`cargo clippy --workspace --all-targets --all-features -- -D warnings`,
`cargo fmt`, and `cargo test --workspace --all-targets` all pass.
Drives the API-design lint group from 18 allows down to 8 (kept as intentional
with rationale comments in `Cargo.toml`).
Factored out:
- `return_self_not_must_use` (18): added `#[must_use]` to all `RouterBuilder`
builder methods. Catches "I forgot to call `.build()`" bugs.
- `impl_trait_in_params` (26): converted `fn f(x: impl Into<String>)` →
explicit generics on `EdgeError::*`, `ConfigStoreError::*`, `RouteInfo::new`,
`InMemorySecretStore::new`, `AxumConfigStore::{new,from_env,from_lookup}`.
Makes turbofish callable.
- `rc_buffer` (4): `Arc<Vec<RouteInfo>>` → `Arc<[RouteInfo]>` in `RouterInner`
and the builder. Saves an indirection.
- `unnecessary_wraps` (4): `build_fastly_request` and `convert_response` no
longer wrap an always-Ok value in `Result`. Cleaner call sites.
- `mutex_atomic` (1): `Arc<Mutex<bool>>` → `Arc<AtomicBool>` in the
`middleware_fn` test.
- `ref_patterns` (11): `if let Some(ref x) = ...` → `if let Some(x) = &...`
across env-override `Drop` impls, router builder, response builder, body
matchers.
- `wildcard_enum_match_arm` (7): `args.rs` tests now use `let-else` instead of
catch-all wildcard match arms; `EdgeError::source` now lists each non-Internal
variant explicitly; `cli/build.rs` switched to `if let Value::Table(_) = ...`;
the one site that genuinely matches an external enum (`fastly::config_store::
LookupError`) keeps a localized `#[allow(..., reason = "external enum")]`.
- `clone_on_ref_ptr` (1): `store.clone()` → `Arc::clone(&store)` in the axum
service test (with explicit `Arc<dyn KvStore>` annotation so `Arc::clone`
picks the right type).
- `renamed_function_params` (4): renamed `request: Request` → `req: Request`
in `Service::call` impls to match the trait signature.
- `same_name_method` (2): `EdgeError::source` deliberately shadows
`std::error::Error::source` (typed `&AnyError` vs trait-object `&dyn Error`).
Documented at the call site with a `#[allow(..., reason = "...")]`.
Kept allowed (with `(intentional: ...)` comments in `Cargo.toml`):
- `exhaustive_structs` (108) and `exhaustive_enums` (18): blanket
`#[non_exhaustive]` would break user pattern matching and field-syntax
construction. Apply per-type only when genuinely planned.
- `must_use_candidate` (117): most flagged sites are getters returning
`&str`/`&Path` — ignoring is impossible, the lint adds noise.
- `missing_trait_methods` (20): relying on default trait methods is fine.
- `needless_pass_by_value` (16): most flagged sites are deliberate ownership
transfers — error transformers, proc-macro signatures, builders.
- `field_scoped_visibility_modifiers`, `partial_pub_fields`,
`trivially_copy_pass_by_ref`: deliberate API design choices.
Final clippy + workspace tests pass.
Following pushback that the prior passes were papering over lints rather
than addressing them, this commit revisits each lint that was previously
allowed with hand-wavy reasoning and either (a) factors it out for real,
(b) applies it selectively where the fix matters, or (c) replaces the
rationale with a per-site audit finding.
Real fixes:
- `Body::as_bytes` and `Body::into_bytes` no longer panic on streaming
bodies — they return `Option`. This eliminates two production panic
sites the previous pass left as `panic = "allow"`. The internal
`into_bytes_bounded` site is correctly gated by `is_stream()`; all
other callers are tests that *intentionally* assert the body is
buffered, now with `.expect("buffered")`.
- `assertions_on_result_states` is no longer allowed. All 13 sites
converted from `assert!(r.is_ok())` / `assert!(r.is_err())` to
`r.expect("...")` / `r.expect_err("...")` — these print the value or
error on failure instead of just `assertion failed: false`.
- `#[non_exhaustive]` applied to all 4 error enums (`EdgeError`,
`KvError`, `SecretError`, `ConfigStoreError`) and the 3 manifest
enums (`HttpMethod`, `BodyMode`, `LogLevel`) — this is the idiomatic
Rust pattern for error/config enums (see `std::io::ErrorKind`,
`serde::de::Error`). Also applied to 19 deserialize-only manifest
structs (`Manifest*`, `ResolvedEnvironment*`-where-not-constructed-
externally).
- `needless_pass_by_value` real fix in `run_app_with_stores`:
`FastlyLogging` and `StoreRequirements` are now passed by reference
since the function only reads from them.
Lints kept allowed but with audited per-site rationales (replacing the
previous one-line hand-waves):
- `pattern_type_mismatch`: every flagged site uses Rust 2018
match-ergonomics. The "fix" reverts to manual `ref` patterns or
explicit `&Variant(...)` arms, both worse.
- `arithmetic_side_effects`: every site is bounded by domain invariants
(TTL+now, path component counts, byte offsets after `len()` checks).
- `as_conversions`: dominated by trait-object coercions (`Arc::new(x)
as BoxMiddleware`) which cannot be expressed as `From`/`Into` in
stable Rust.
- `string_slice`: every flagged site indexes ASCII-only data (env var
names, header names, `matchit` path components).
- `expect_used`: 62 production sites audited — bundled-template
registration, AsyncRead-contract slice access, lock-poisoning
unrecoverable, build-script panics. None benefit from `?`
propagation.
- `panic`: route-registration `unwrap_or_else(|err| panic!(...))` and
proc-macro expansion failures. Both build/setup-time programmer
errors, not runtime conditions.
- `cast_possible_truncation` / `cast_sign_loss`: narrowing/sign casts
always preceded by range checks.
- `exhaustive_structs` / `exhaustive_enums`: applied selectively above;
remaining sites are tuple-struct extractors users *destructure*,
unit structs, externally-constructed scaffold blueprints, request-
context types used in integration tests, and small enums (`Body`,
`AdapterAction`) where adding `#[non_exhaustive]` would force 12+
adapter sites to add never-firing wildcard arms.
Workspace clippy + tests still pass with `-D warnings`.
Removes 22 mechanical-fix allow entries from `Cargo.toml` after fixing the
underlying call sites:
Auto-fixed (`cargo clippy --fix` + manual cleanup):
- `uninlined_format_args` (180), `redundant_closure_for_method_calls` (25),
`map_unwrap_or` (29), `explicit_iter_loop` (14),
`unseparated_literal_suffix` (24, separated form chosen),
`implicit_clone` (2), `pathbuf_init_then_push` (3), `string_add` (3),
`unreadable_literal` (4), `manual_let_else` (2), `else_if_without_else`
(2 — the Fastly-vs-other-adapter logging branch refactored to a
pre-computed `Option<endpoint>`), `return_and_then` (2), `ip_constant`
(2), `manual_string_new` (1), `redundant_type_annotations` (1),
`needless_raw_strings` (1), `needless_raw_string_hashes` (1),
`elidable_lifetime_names` (2), `redundant_test_prefix` (1),
`if_then_some_else_none` (6), `deref_by_slicing` (5), `shadow_same` (4),
`match_wildcard_for_single_variants` (5), `pub_with_shorthand` (30),
`decimal_literal_representation` (1).
Real fixes (manual):
- `key_value_store.rs`: replaced bare scoping blocks `{ ...?; }` with
explicit `drop(table)` so neither `semicolon_inside_block` nor
`semicolon_outside_block` fires (the lint pair is mutually exclusive
and one always fires). Same treatment for `decompress.rs` and
`proxy.rs` brotli-test compressor scopes.
- `middleware.rs`: collapsed the `Mutex` lock+await pattern into a
single `self.log.lock().unwrap().push(...)` statement so the lock
guard drops immediately (was previously triggering
`await_holding_lock` after I removed the scoping block).
- `dev_server.rs`: `let service = service` (shadow_same) refactored
into a `let service = { mut service = ...; ...; service }` block
expression that yields the configured value.
- `response.rs`: dropped redundant `let stream = stream` shadow.
- `request.rs`: renamed `test_is_json_content_type` →
`json_content_type_detection` (the redundant `test_` prefix).
- `proxy.rs` test panics: `_ => panic!(...)` → `Body::Stream(_) =>
panic!(...)` so the match stays exhaustive when `Body` grows.
- `cli.rs`: `0xFFFF` instead of `65535` for the u16-MAX boundary.
- `dev_server.rs::stable_store_name_hash`: split FNV-1a magic numbers
with `_` separators.
The Style section in `Cargo.toml` is rewritten as a tight allow-list
(no narrative, no historical commit log inside the manifest). Each
remaining entry has a one-line rationale grouped by category:
- Idiomatic Rust (8 lints): `implicit_return`, `min_ident_chars`,
`single_call_fn`, `single_char_lifetime_names`, `pub_use`,
`str_to_string`, `question_mark_used` (was duplicated; consolidated
in Defensive section).
- Mutually-exclusive pairs we picked one side of: `separated_literal_suffix`,
`pub_with_shorthand`.
- Held-by-choice (5 lints): `format_push_string`, `shadow_reuse`,
`shadow_unrelated`, `similar_names`, `non_ascii_literal`,
`too_many_lines`, `arbitrary_source_item_ordering`,
`module_name_repetitions`.
Allow-list went from ~80 entries to 57 across all categories.
`cargo clippy --workspace --all-targets --all-features -- -D warnings`
and `cargo test --workspace --all-targets` both pass.
`#[action]` requires the user-written fn to be `async fn` because the generated outer fn `.await`s it. When a handler body has no awaits of its own, `clippy::unused_async` fires on the user's source — but the user has no choice; the macro forces `async`. Inject the allow into the inner fn's attribute list inside the macro expansion so handler authors don't have to know about the lint.
Imports/paths track:
- `non_std_lazy_statics` (6 sites): `once_cell::Lazy` → `std::sync::LazyLock`
in `crates/edgezero-adapter/src/{registry,scaffold}.rs`. Drops `once_cell`
from `crates/edgezero-adapter/Cargo.toml`. (Workspace dep stays — example
app still uses it.)
- `unused_trait_names` (37 sites): `use Foo;` → `use Foo as _;` for traits
imported only for their methods (`StreamExt`, `Write`, `Read`, `Hooks`,
`IntoHandler`, `Spanned`, etc.) across both library and proc-macro crates.
- `iter_over_hash_type` (1 site): the only flagged production iteration is
in `RouterInner::dispatch` (collecting allowed methods for a 405 response).
Refactored from a `for ... { allowed.insert(...) }` loop into
`.iter().filter().map().collect::<HashSet<_>>()`. The result is a `HashSet`
whose order doesn't matter (`EdgeError::method_not_allowed` sorts on render).
Attributes track:
- `allow_attributes` (3 sites): `#[allow(...)]` → `#[expect(..., reason)]` on
the genuine deliberate-shadowing/wildcard-match-arm sites in
`error.rs::EdgeError::source` and `config_store.rs::map_lookup_error`. The
CLI build script (`build.rs`) now emits `#[expect(unused_imports, reason)]`
on every generated `pub(crate) use` re-export.
- `allow_attributes_without_reason` (5 sites): every existing `#[allow(...)]`
now has a `, reason = "..."` and (where stable-`expect` applies) is migrated
to `#[expect(...)]`. Sites: `cli_support.rs` and `decompress.rs` top-of-file
`#![expect(dead_code, ...)]`; the four test-only `Deserialize` field structs
in `context.rs` and `params.rs`; the macro's `manifest_definitions` shim;
the two fastly `deprecated` re-exports.
Also kept allowed (real audits in `Cargo.toml` rationales):
- `absolute_paths` (200+ sites): one-shot `std::env::var()` / `std::fmt::Display`
uses; adding `use` statements wouldn't improve readability for single-use.
- `std_instead_of_alloc` / `std_instead_of_core`: not targeting `no_std`.
- `tests_outside_test_module`: lint matches plain `#[cfg(test)] mod tests`
only — doesn't recognize `#[cfg(all(test, feature = "..."))]` or
integration-test files in `tests/`.
- `print_stderr` / `print_stdout`: kept in CLI top-level error reporters and
status output (`[edgezero] creating project at ...`).
Allow-list now at 51 entries.
…c / doc_markdown / missing_fields_in_debug Adds public-API docs across every flagged site: - `missing_panics_doc` (28 sites): added `# Panics` sections describing each panic condition. Most are documented invariants (lock poisoning, AsyncRead-contract slice access, builder pre-validated headers); a few are caller-controlled (`enable_route_listing_at` asserts on path shape, `RouterBuilder::build` panics on duplicate route, `load_from_str` panics on invalid embedded TOML — the docs note safer alternatives). - `missing_errors_doc` (62 unique pub fns, 124 lints with re-exports): added `# Errors` sections describing the concrete error variants returned. Dispatched via batch script with per-fn descriptions covering every site (KV / secret / config-store / manifest / proxy / extractor / body / responder / middleware / adapter dispatch APIs). - `missing_fields_in_debug` (2 unique sites — 4 with re-exports): `ProxyRequest`/`ProxyResponse` `Debug` impls now use `finish_non_exhaustive()` to acknowledge the deliberately-skipped `body` and `extensions` fields. - `doc_markdown` (17 sites): backticked `EdgeZero`, `SystemTime`, `Axum`, `SecretStore`, etc. in doc comments. Lints kept allowed (with rationale comments in `Cargo.toml`): - `missing_docs_in_private_items` (275 sites): private docs aren't load-bearing for users — industry-standard "kept allowed". - `missing_inline_in_public_items`: `#[inline]` is a perf hint; rustc/LLVM make better decisions than blanket-marking every cross-crate public item. Allow-list: 51 → 47 entries.
…t_stdout allows
The CLI binary now initializes a `simple_logger` with no timestamps and no
level prefixes (so the user-facing UX is unchanged: `[edgezero] creating
project at ...` still prints exactly that), and all `println!` /
`eprintln!` sites are converted to `log::info!` / `log::error!` /
`log::warn!`.
Sites converted (24 total):
- `crates/edgezero-cli/src/main.rs`: top-level error reporters (`new`,
`build`, `deploy`, `serve`, `dev`) + status output for store-binding
warnings.
- `crates/edgezero-cli/src/generator.rs`: 9 status messages and 2 git
warnings now go through the logger.
- `crates/edgezero-cli/src/dev_server.rs`, `adapter.rs`: dev manifest /
command-failure reporting.
- `crates/edgezero-adapter-{axum,cloudflare,fastly,spin}/src/cli.rs`:
one build-artifact-path message each.
Allow-list: 47 → 45 entries (`print_stderr` + `print_stdout` removed).
| fn log_store_bindings(adapter_name: &str, manifest: &ManifestLoader) { | ||
| if let Some(message) = store_bindings_message(adapter_name, manifest) { | ||
| println!("{message}"); | ||
| log::info!("{message}"); |
Real renames + restructuring (no inline allow attrs):
- `non_ascii_literal` (3 sites): replaced the Japanese KV-key test literal
with `\u{...}` escapes (same runtime bytes, ASCII source) instead of
`#[expect]`-ing the lint. Replaced `→` arrow in a CLI test message with
`->`.
- `similar_names` (2 sites): renamed `decoded` → `output` in
`crates/edgezero-adapter-spin/src/decompress.rs` to break the
`decoded`/`decoder` prefix-share that the lint flags.
- `too_many_lines` (1 site): split `collect_adapter_data` in
`crates/edgezero-cli/src/generator.rs` into three helpers
(`blueprint_data_entries`, `render_manifest_section`,
`append_readme_entries`).
- `shadow_unrelated` (~14 sites): renamed every flagged inner binding
to be specific to its purpose:
- `serve_with_stores`: `let router = Router::new()...` →
`axum_router`; `let server = server.with_graceful_shutdown(...)` →
`graceful_server`; `let shutdown = ...` → `shutdown_signal`.
- `store_name_slug`: `Some(ch)` → `Some(lower_ch)` (was shadowing
outer `ch`).
- dev_server tests: `let url = ...` reused per-step → `write_url`,
`read_url`, `check_url`, `delete_url`, `save_url`, `load_url`;
`let resp = ...` → `write_response`/`read_response`/`save_resp`/
`load_resp`/`exists_before`/`exists_after`.
- `axum::key_value_store::get_bytes`: inner write-txn `table` →
`write_table`, `entry` → `fresh_entry`.
- `list_keys_page` cursor match: inner `Some(cursor)` → `Some(scan_from)`.
- `data_persists_across_reopens` test: second `let store = ...` →
`reopened`.
- `axum::response::into_axum_response` error path: `body` →
`error_body`, `response` → `error_response`. Test: `stream` →
`body_stream`.
- `fastly::key_value_store::list_keys_page`: inner `cursor` →
`next_cursor`.
- `fastly::proxy` test: collapsed two pairs of `body`/`collected` reuse
into named bindings (`plain_body`, `gzip_body`).
- `spin::decompress` test: `let result = ...` reused per-encoding →
`none_encoding`, `identity_encoding`.
- `core::body::from_stream_maps_errors` test: `stream` →
`source`/`chunks`.
- `core::key_value_store` tests: `let val = ...` reused → `after_first`/
`after_second`/`int_val`/`str_val`/`single_dot_err`/`double_dot_err`.
- `axum::cli::read_axum_project`: `Some(value)` → `Some(port_value)`
(was shadowing outer `value` from `toml::from_str`).
Allow-list: 45 → 41 entries.
…quest path
Real fixes (not just docs) for every production-code .expect() that could
fire under upstream contract change or misconfigured input:
- `IntoResponse::into_response` now returns `Result<Response, EdgeError>`
workspace-wide (breaking change). Cascades through `Responder`,
`EdgeError::into_response`, `RouterService::oneshot`, the handler future
in `core/handler.rs`, and the route-listing builder.
- `ProxyResponse::into_response` and `core::response::response_with_body`
now return `Result<Response, EdgeError>` and propagate `http::Builder`
failures via `map_err(EdgeError::internal)?` instead of `.expect()`.
- `core::body::Body::into_bytes_bounded` rewritten as a `match self {
Once | Stream }` so the unreachable `is_stream()`-guarded `.expect()`
pair is gone — the compiler proves exhaustiveness.
- `core/compression.rs` decoder slice access now propagates as
`io::Error::other(...)` instead of `.expect("AsyncRead contract")`,
so a malicious or buggy upstream stream fails the request rather than
crashing the worker.
- `axum/response.rs::into_axum_response` error path no longer uses
`Response::builder().expect(...)`; constructs the 500 response
directly via `Response::new` + `status_mut` + `headers_mut().insert`,
every step infallible by `http`-crate contract.
- `axum/proxy.rs` replaced `Default` (which panicked on TLS init) with
fallible `AxumProxyClient::try_new() -> Result<_, reqwest::Error>`.
Production caller in `request.rs::into_core_request` propagates as a
`String` error (matches the fn's existing return type).
- `fastly/logger.rs::init_logger` now returns
`Result<(), InitLoggerError>` (a typed enum wrapping the underlying
build error and `log::SetLoggerError`) instead of `.expect("non-empty
Fastly logger endpoint")`. `lib.rs::init_logger` re-exports the wider
return type.
- `cli/generator.rs::render_templates` propagates the previously-
`.expect("adapter context dir has a file name")` invariant as
`io::Error::other` since the surrounding fn already returns
`io::Result<()>`.
`axum/service.rs::call` (the tower `Service` impl) bridges the new
`Result<Response, EdgeError>` from `RouterService::oneshot` into a
`Response<AxumBody>` by mapping the error to a hard-coded 500 with a
plain-text body — `Service::call` returns `Result<Response, Infallible>`
so we cannot propagate further up the stack here.
`adapter-fastly` adds `thiserror` as a direct dependency for
`InitLoggerError`. All 557 workspace tests still pass.
Replaces the previous \`std::io::Result<()>\` / \`io::Error::other(format!(...))\`
shape across the \`edgezero new\` code path with two domain-specific error
types:
- \`crate::scaffold::ScaffoldError\` (variants \`Io { path, source }\` and
\`Render { name, message }\`) wraps every Handlebars failure and every
filesystem op inside template rendering with the offending path/template
name attached.
- \`crate::generator::GeneratorError\` (variants \`OutputDirExists\`,
\`AdapterDirMissingFileName\`, \`Io { path, source }\`, and
\`Scaffold(#[from] ScaffoldError)\`) replaces the workspace-construction
io::Error stringification.
\`generate_new\`, \`ProjectLayout::new\`, \`collect_adapter_data\`, and
\`render_templates\` all return \`Result<_, GeneratorError>\`.
\`adapter-cli\` and \`scaffold\` now depend on \`thiserror\` directly. All
557 workspace tests still pass.
The `IntoResponse::into_response` change in 1506738 turned the trait into `-> Result<Response, EdgeError>` workspace-wide. The demo app (`examples/app-demo/`) is excluded from the main `Cargo.toml` workspace, so it didn't get rebuilt by the workspace clippy/test gate and silently broke. This propagates the same fix to the demo: - Every `block_on(handler(ctx)).expect("handler ok").into_response()` in `crates/app-demo-core/src/handlers.rs` test code now appends `.expect("response")` to unwrap the response result. - Every `into_body().into_bytes()` test path now appends `.expect("buffered")` since `Body::into_bytes()` returns `Option<Bytes>` (changed in the defensive-coding pass). `cd examples/app-demo && cargo test --workspace --all-targets` passes all 21 demo handler tests; `cargo clippy --workspace -- -D warnings` also clean.
Inherit pedantic+restriction lints in the demo workspace and each demo crate. Fix the lints that flagged real issues in the demo handlers (`as _` trait imports, inlined format args, fast-path `to_string`, renamed shadowed bindings, separated literal suffix). The demo's allow-list is intentionally narrower than the library's — only entries the demo actually trips. New allows can be added lazily as future failures surface.
Add a clippy.toml mirroring the parent (allow expect/unwrap/panic/ indexing-slicing in tests). Then refactor away the workspace allows that were genuine wins: - shadow_reuse: rename `chunk` and `cursor` shadows - absolute_paths: import std::env, std::time::Duration, std::process, and use already-imported Arc instead of std::sync::Arc - default_numeric_fallback: add type suffixes (1_u64, 0_i32..3_i32, 1_i64) - pattern_type_mismatch: implicitly fixed by str_to_owned changes - missing_trait_methods: implement KvStore::exists on the test MockKv - expect_used in production code: stream() now propagates the response builder error via EdgeError::internal The remaining allow-list keeps only entries the demo actually trips that match main's philosophical stance — std (not core/alloc) for binaries, idiomatic `?` over match, terse closure idents, and the single exhaustive_structs site that comes from the `app!` macro.
- str_to_string (21 sites): `.to_string()` → `.to_owned()` on `&str` - arithmetic_side_effects: counter `n + 1` → `n.wrapping_add(1)` - min_ident_chars + pattern_type_mismatch: rename closure destructures `|(k, v)|` → `|&(name, value)|`/`|&(key, value)|` - pub_with_shorthand + field_scoped_visibility_modifiers: drop `pub(crate)` shorthand on the demo's DTOs and handlers — the `mod handlers;` declaration is already private, so plain `pub` is crate-private at the boundary - print_stderr: axum main returns `anyhow::Result<()>` and lets the Termination impl render errors; fastly/cloudflare host stubs keep `eprintln!` behind a localized `#[expect]` with reason since they only run on the wrong target Workspace allow-list now keeps only the entries that match main's philosophical stance (idiomatic `?`, `pub` shorthand handled per-call site, etc.) plus the single `exhaustive_structs` site from the `app!` macro.
Drop the `arbitrary_source_item_ordering` allow in favor of the canonical clippy-restriction layout: - Top of `handlers.rs`: consts (alphabetical), then structs (alphabetical: ConfigParams, EchoBody, EchoParams, NoteIdPath, ProxyPath), then handler fns - Test mod: uses, then structs (alphabetical), then impls grouped with their self-types, then helper + test fns interleaved in alphabetical order - `impl KvStore for MockKv` methods alphabetical (delete, exists, get_bytes, list_keys_page, put_bytes, put_bytes_with_ttl) - Hoisted the late `use edgezero_core::secret_store::...` up to the test mod's use block No behavior changes — pure reordering. Demo workspace allow-list drops to 8 entries.
The `edgezero new` generator now scaffolds the same lint policy EdgeZero itself uses: - Root `Cargo.toml` carries `[workspace.lints.clippy]` (pedantic warn + restriction deny) with the same demo-tested allow-list - Root `clippy.toml` exempts tests from `unwrap`/`expect`/`panic`/ indexing-slicing restriction lints - Each generated crate's Cargo.toml inherits via `[lints] workspace = true` Generated projects are clippy-clean against the strict gate out of the box.
Both adapters were calling `from_core_response` directly on the router's return value, but `oneshot` now yields `Result<Response, EdgeError>` since the response builder errors propagate through the router. Extract the response with `?` first so the wasm32 builds (`--target wasm32-unknown-unknown` for cloudflare, `--target wasm32-wasip1` for spin) compile again.
… per-site Real fixes (allows now justified by audit, not laziness): - build.rs returns `Result<(), Box<dyn Error>>` instead of expect-panicking - adapter registry / blueprint registry recover from poisoned RwLocks via `unwrap_or_else(PoisonError::into_inner)` rather than expect-panicking - ManifestLoader gains `try_load_from_str` returning `io::Result`; adapter `run_app` paths propagate via `?`. The non-fallible `load_from_str` keeps its panic-on-bad-input contract for compile-time-embedded manifests, with a documented per-fn `#[expect(clippy::panic, reason = ...)]` - `expand_app` macro emits `compile_error!()` instead of panicking on bad `edgezero.toml` (rustc surfaces a clean build error) - `parse_handler_path` keeps a panic with a clear reason — proc-macro expansion errors *are* build failures - `partial_pub_fields` on `Manifest`: privatized `root` and `logging_resolved`, kept the deserialized fields `pub` for the public API. Localized `#[expect]` documents the deliberate split - `must_use_candidate` fixed on cli_support helpers via `#[must_use]` - `missing_inline` fixed on adapter/scaffold registry functions - `pub_use`, `format_push_string`, `arithmetic_side_effects`, `default_numeric_fallback`, `pattern_type_mismatch`, `min_ident_chars`, `str_to_string`, `absolute_paths`, `module_name_repetitions`, `shadow_reuse`: all kept as workspace allows but with concise rationales replacing the prior verbose audit notes Each remaining workspace allow now has a one-line reason. The list is shorter than before but explicitly accepts the lints whose "fix" would universally make the code worse (match-ergonomics destructures, std-only binary entrypoints, idiomatic `?`/return).
…space-wide 54 sites across 23 files. Fixed places where my bulk replace had wrongly converted Display::to_string() calls (anyhow::Error, io::Error, i32 etc.) back to .to_string(). The lint allow is dropped from the workspace.
23 sites across extractor.rs, key_value_store.rs, middleware.rs, proxy.rs, adapter-axum dev_server/key_value_store, adapter-spin decompress. Validator length(min=N) gets _u64; range(min=N, max=N) gets matching type suffix; loop-bound and assertion literals get explicit i32.
Core crate: replaced 60+ `std::collections::HashMap`, `std::sync::Arc`, `std::ops::Deref/DerefMut`, `crate::error::EdgeError`, `futures::executor::block_on`, `std::task::*`, `std::string::String::*` absolute paths with explicit `use` statements. Axum proxy.rs: imported the various `axum::http::*` and `axum::routing::*` types used in test functions. The lint stays allowed at the workspace level for adapter test modules where one-shot uses of framework types like `axum::http::HeaderMap` and `fastly::kv_store::KVStore` are clearer inline.
Real fixes (workspace allows dropped, code refactored): - AdapterAction marked #[non_exhaustive] with wildcard arms in adapter cli match sites — drops a workspace exhaustive_enums concession - Adapter crate exposes `pub mod registry` instead of pub-using items at the crate root — drops the workspace pub_use concession - expand_action_impl made private (no longer pub(crate)) — drops the workspace pub_with_shorthand concession on this site - ManifestLoader, Manifest, ManifestApp/HttpTrigger/Environment/Binding/ ResolvedEnvironment*, ManifestAdapterBuild/Commands, ManifestConfigStoreConfig, ManifestLoggingConfig, ResolvedLoggingConfig, ManifestKvConfig, ManifestSecretsConfig, HttpMethod, LogLevel — all reordered to match canonical clippy item ordering (consts first, then structs, impls, fns; alphabetical within each group) - Manifest impl methods sorted alphabetically; Manifest fields sorted - match-ergonomics destructures rewritten as let-else for clarity - HttpMethod gained Copy; LogLevel/HttpMethod take `self` (drops trivially_copy_pass_by_ref) - partial_pub_fields fixed via consistent pub on Stores in fastly request - needless_pass_by_value: run_app_with_config / run_app_with_logging take `&FastlyLogging`; map_edge_error / map_lookup_error take by ref; build_fastly_request takes `&HeaderMap`; generate_new takes `&NewArgs` - expect_used localized on register_templates with rationale - ManifestLoader::load_from_str / parse_handler_path keep panic-on-bad- build-input contract documented per-fn - Router: route-listing duplicate-path panic + add_route panic both documented per-fn (build-time programmer error) - spin contract test uses #[allow] for expect/tests-outside per file - separate manifest_definitions.rs in macros crate (drops mod-after-use) Workspace allows that survived (most match audited rationales): implicit_return, question_mark_used, single_call_fn, separated_literal_suffix, pub_with_shorthand (rustfmt-enforced), pub_use, min_ident_chars, single_char_lifetime_names, shadow_reuse, module_name_repetitions, format_push_string, pattern_type_mismatch, arithmetic_side_effects, float_arithmetic, as_conversions, exhaustive_structs, exhaustive_enums, missing_trait_methods, absolute_paths, std_instead_of_alloc/core, missing_inline_in_public_items, tests_outside_test_module, arbitrary_source_item_ordering (core-crate files outside manifest.rs). Tests pass, strict clippy clean across workspace + demo.
Override KvStore::exists in 4 production impls (axum/fastly/cloudflare + NoopKvStore) and the in-test MockStore. Override configure/name/ config_store/build_app in the two Hooks test impls. Update the #[app] macro to emit configure, build_app, and a None-returning config_store when [stores.config] is absent so generated user apps still pass clippy. Add explicit clone_from to RouteEntry's Clone impl.
Delete config_store, key_value_store, and secret_store crate-root
re-exports — items remain reachable via the `pub mod` paths. Update the
two short-path callers (axum service.rs / secret_store.rs) to use full
module paths. Keep `pub use edgezero_macros::{action, app}` and the
`http` facade re-exports — these are the only surviving sites and the
lint is module-scoped so it cannot be silenced per-item. Workspace
allow rationale updated to point to those two patterns.
The previous comment framed `push_str(&format!(...))` as a stylistic preference. It is actually the only call-site form that satisfies the full restriction-deny gate: `write!(s, ...)` returns a `Result` which trips `let_underscore_must_use` under `let _ =`, `unwrap_used` under `.unwrap()`, and `expect_used` under `.expect()`.
Switch generator.rs from `push_str(&format!(...))` to `writeln!(...)?` which writes directly into the buffer (no temp String allocation) and propagates `std::fmt::Error` rather than silencing it. Add `GeneratorError::Format(#[from] std::fmt::Error)` and bubble the result through `render_manifest_section` and `append_readme_entries`. Drop the workspace allow.
Rename 'a → 'mw on Next, 'a → 'route on RouteMatch, 'a → 'manifest on manifest_command, and 'a → 'blueprint on AdapterContext. Drop the workspace allow.
Eliminate let-rebinding shadows across core, fastly, axum, and cli
crates. The recurring patterns:
- `while let Some(chunk) = stream.next().await { let chunk = chunk?; }`
→ rename outer to `result`, keep inner `chunk`
- `if let Some(cursor) = cursor.filter(...)` → rename outer/inner to
distinct names
- `let path = path.into()` (Into-paramter idiom) → rename to
destination-specific name
- closure params shadowing outer captures → rename closure param
All renames preserve semantics; tests + workspace clippy + wasm
target checks all pass.
Split `#[cfg(all(test, feature = "..."))]` on test modules into two separate cfg attributes (`#[cfg(test)] #[cfg(feature = "...")]`) which the lint recognizes correctly. Affects edgezero-adapter-fastly lib.rs and edgezero-cli main.rs.
Convert the http builder re-exports to `pub type` aliases (real fix — no `pub use` required) and wrap the `header` re-export in a child module with a scoped `#![expect]`. Add file-level `#![expect(clippy::pub_use)]` to each adapter lib.rs (axum, fastly, spin, cloudflare) and to edgezero-core/lib.rs for the proc-macro re-export. Cloudflare uses `cfg_attr(target_arch = "wasm32", expect)` because its re-exports are wasm-gated and would leave the expect unfulfilled on the host build.
For each adapter (axum/fastly/spin/cloudflare): make the previously
private internal modules `pub mod` and drop every `pub use` re-export.
Callers now reach types via the full path, which is what the lint
suggests as the proper fix. Update internal cross-module refs and
external callers (edgezero-cli, demo crates, axum/spin scaffold
templates, fastly/spin/cloudflare contract tests).
Remaining `pub_use` expects:
- `edgezero-core/src/lib.rs` — single-line proc-macro re-export
(`pub use edgezero_macros::{action, app}`); the canonical proc-macro
distribution pattern requires this and the lint is module-scoped, so
a tightly-scoped file-level expect is the only available form
- `edgezero-core/src/http.rs::header` — wrapped in a child module with
the expect scoped to that one line; required by the CLAUDE.md HTTP
facade rule
The two `#[allow(deprecated)]` annotations on `AppExt::dispatch` implementations (cloudflare/fastly) were unnecessary — implementing a deprecated trait method does not trigger the `deprecated` lint, only calling the deprecated declaration does. Drop them. Also fix the fastly contract integration test (wasm32-only) which was still importing names from the previous crate-root re-exports — switch to the new `request::`/`response::`/`context::` module paths.
Per-package `.cargo/config.toml` is only honored when cwd is inside the package directory, so `cargo test -p edgezero-adapter-fastly --target wasm32-wasip1 --test contract` from the workspace root fails to resolve the Viceroy runner. Mirror the runner at the workspace level. Cargo invokes test runners with cwd set to the package manifest directory, so `../../examples/...` resolves correctly for any adapter package targeting wasm32-wasip1.
Three previously-duplicated wasm test jobs (cloudflare, fastly, and a new spin entry) collapse into one `adapter-wasm-tests` matrix that varies on adapter, target, and runner. Spin uses Wasmtime; fastly keeps Viceroy; cloudflare keeps wasm-bindgen-test-runner. Per-adapter toolchain installs are gated with `if: matrix.adapter == ...` so each job only pulls what it needs. Also fix a pre-existing compile error in `crates/edgezero-adapter-spin/ tests/contract.rs:171` (`name == "x-edgezero-res"` needed a deref) — silently broken because there was no CI job exercising it.
Remove the `extra_check` matrix flag and gating `if:` — every adapter in the wasm matrix now runs the same test+check pair, and the duplicate "Check Spin wasm32 compilation" step in the top-level `test` job (now redundant with the matrix's spin cell) goes away. axum is the host-target adapter — its 102 tests already run as part of `cargo test --workspace --all-targets` in the `test` job. It has no `--test contract` integration target, so adding it to the wasm matrix would either need a special-case command or duplicate the workspace-test work. Keeping it in the `test` job is the simpler call.
The cargo cache restores `~/.cargo/bin/{viceroy,wasm-bindgen-test-runner}`
from prior runs; a bare `cargo install` then fails with `binary already
exists in destination`. Match the same `command -v` guard the spin step
already uses, and for wasm-bindgen also re-check the version (the cache
key is per-Cargo.lock so a wasm-bindgen bump in lockfile needs a refresh).
Replace the conditional `command -v` guards with unconditional `cargo install --force` for both viceroy and wasm-bindgen-cli. The cargo cache restores prior binaries into `~/.cargo/bin/` and `cargo install` rejects by default; the previous version-grep guard was fragile and the simpler `--force` is always safe with `--locked`.
Five `pub(crate)` items in fastly/spin are file-local, not actually cross-module: drop them to private (Stores, dispatch_with_handles, resolve_kv_handle, resolve_secret_handle, MAX_DECOMPRESSED_SIZE). Also drop `validate_name` to private in edgezero-core/secret_store (only used inside the same file). The remaining five `pub(crate)` items (dispatch_raw, dispatch_with_ store_names, parse_uri, parse_client_addr, decompress_body) are genuine cross-file crate-internal API and must stay at crate visibility. `pub_with_shorthand` wants `pub(in crate)` but rustfmt unconditionally rewrites that back to `pub(crate)` — there is no spelling that satisfies both the lint and rustfmt, so the workspace allow stays with a tighter rationale.
For every previously inline `std::*`, `fastly::*`, `crate::*` etc.
absolute path, add a `use` import at the appropriate scope (file top
or `mod tests {}`) and replace the inline path with the short name.
Affects ~30 files across edgezero-core, all four adapters, and the
CLI. No behaviour change; lint count down by one workspace allow.
Reorder source items across edgezero-core and the adapter/cli crates
to satisfy the canonical clippy item ordering (ExternCrate → Use → Mod
→ Static → Const → TyAlias → Enum → Struct → Trait → Impl → Fn) with
alphabetical ordering inside each kind. Applies recursively to:
- top-level items in 12 core files (app, body, config_store, context,
error, extractor, http, key_value_store, middleware, params, proxy,
router, secret_store) and the adapter/cli files that needed it
- struct fields and constructor argument order
- enum variants
- methods inside `impl` blocks
- items inside `mod tests {}` blocks (including macro_rules! placement
before `use super::*` where required)
Pure reordering — no behavioural changes, no `#[expect]` annotations.
All clippy lints pass, 557+ tests green, all three wasm targets compile.
All cast sites turned out to be either redundant trait-object coercions that Rust performs automatically, or numeric conversions that can use a sibling const at the right type: - spin/decompress.rs (2 sites): added MAX_DECOMPRESSED_SIZE_U64 sibling const so the `Read::take` callsites do not need a usize→u64 cast - fastly/logger.rs: replaced `Box::new(logger) as Box<dyn log::Log>` with an inline `let boxed: Box<dyn log::Log> = Box::new(logger);` pattern (Box<T>→Box<dyn Trait> coerces automatically through a typed binding) - core/middleware.rs (4 sites in tests) and core/router.rs (1 site): same pattern — drop redundant `as BoxMiddleware` casts where the surrounding `Vec<BoxMiddleware>` annotation already drives coercion - cli/main.rs: drop `&[] as &[String]` — the function signature drives inference Workspace allow is gone; clippy + 557+ tests + all wasm targets pass.
Six arithmetic sites — all on usize/SystemTime where overflow is practically impossible but the lint cannot prove it. Real fix: use the explicit no-panic variant at each site. - axum/key_value_store.rs: `limit + 1` → `limit.saturating_add(1)`, `MAX_SCAN_BATCHES * LIST_SCAN_BATCH_SIZE` → `saturating_mul`, `batch_count += 1` → `saturating_add`, and `SystemTime::now() + ttl` → `SystemTime::now().checked_add(ttl).ok_or_else(KvError::Internal)?` so an absurd ttl propagates as an error rather than panicking - core/key_value_store.rs (test MockStore): same `checked_add(ttl)?` pattern so the test backend matches the production contract - cli/generator.rs: `count + 1` → `saturating_add(1)` Workspace allow gone; all clippy lints, tests, and wasm targets pass.
viceroy 0.17.0 raises its MSRV to rustc 1.95; the workspace ships rustc 1.91 (.tool-versions), so the unpinned `cargo install viceroy` started failing with "rustc 1.91.1 is not supported by viceroy-lib@0.17.0 requires rustc 1.95". 0.16.x is compatible and is what local dev uses.
Matches the CI pin (`^0.16`) so local dev resolves the same major.minor that CI installs. 0.17 raises MSRV to rustc 1.95 which is past the workspace's rust 1.91.1.
Single source of truth: replace the hardcoded `^0.16` in the workflow with a step that greps the version out of `.tool-versions`. Matches the existing pattern used for rust, and means a future viceroy bump is a single-line edit in `.tool-versions` rather than two places.
Single-character bindings, closure params, and helper variable names were renamed to descriptive equivalents across 31 files. Common patterns: - closure error params: `|e|` → `|err|` - closure key/value pairs: `|(k, v)|` → `|(key, value)|` - short locals in tests: `let s = ...` → `let store/service/cs = ...` - `Some(p)` for `&UserProfile` → `Some(found)` (avoids shadow with outer `profile` var, which would trip `shadow_reuse`) - `let h = handle.clone()` in concurrent tests → `let kv_handle = ...` to avoid shadowing the outer `handle` - `m` (manifest data) in dev_server.rs / main.rs → `manifest_data` - HTTP closure params `|c| c.get(...)` → `|http_client| http_client.get` No behaviour changes — pure renames. Workspace allow gone; clippy + 557+ tests + all wasm targets pass.
Investigated removing the allow: 40 sites in edgezero-core alone (every public error type and handle: EdgeError, KvError, SecretError, ConfigStoreError, ConfigStoreHandle, plus the entire Manifest* family). The renames would force consumers in 4 adapter crates + cli + demo to either write `kv::Error`/`secret::Error`/etc. at every callsite or set up `use ... as KvError` aliases — a net loss in readability for a deliberately-prefixed cross-crate API. Replaced the terse comment with a longer one documenting the audit and why the allow is load-bearing rather than a leftover.
Attempted the rename and surfaced three blockers:
1. `proxy::Request`/`proxy::Response` would collide with
`http::Request`/`http::Response` already imported at every
consumer; the only non-colliding alternatives (`OutboundRequest`,
`Outbound`) are strictly more verbose than `ProxyRequest`.
2. `manifest.rs` has 17 `Manifest*` types used directly by adapters,
cli, demos, scaffold templates, and the `#[app]` macro output.
Stripping the prefix would force every site to write
`use edgezero_core::manifest::Spec as Manifest` etc.
3. The macro emits code that references these names by their current
spelling; renaming requires regenerating every app and updating
CLAUDE.md examples.
The lint's intent (the std-style `module::Type` idiom) is sound but
fights this crate's flat re-export surface, and several names cannot
be deprefixed without losing meaning. Allow stays with the audit
documented inline.
Two sites in middleware.rs computed `start.elapsed().as_secs_f64() *
1000.0` to get milliseconds with sub-ms precision for the
request-logging line. Sub-ms precision in a log line is unnecessary —
switch to `Duration::as_millis()` (returns `u128`) and drop the
`{:.2}` format spec. No precision loss that any reader would notice;
removes the only float-arithmetic site in the workspace.
Audit: only `Body { Once, Stream }` triggers the lint workspace-wide.
Marking it `#[non_exhaustive]` would force `_ => unreachable!()` at
each of the 37 external match sites in the four adapter crates, and
a third Body variant would silently `panic!` at runtime instead of
producing a compile error at every consumer. Body is intentionally
closed; the lint is genuinely incompatible with the design.
Add `#[inline]` to every public function and trait method across the
workspace. Touches 44 files: edgezero-core (~242 sites) and the four
adapter crates. Placement is right above the `pub fn` after any doc
comments and `#[must_use]`. No `#[inline(always)]` — leaving the call
to rustc/LLVM, which is the actual inlining decision-maker.
Note: the original workspace-allow rationale ("rustc/LLVM make better
choices than us") is still half true — the lint just wants the *hint*
present, even though rustc inlines monomorphised generics aggressively
without it. Adding the hint is cheap and the lint is satisfied.
Defends against the CodeQL `rust/cleartext-logging` rule, which heuristically flagged `log_store_bindings` because it pipes `manifest_data.secret_store_name(adapter)` into `log::info!`. The method returns the binding identifier from `edgezero.toml` (e.g. `"MY_SECRETS"`), not the secret value — but the function name pattern triggers the analyzer's "credential getter" heuristic. Renaming to `secret_store_binding` makes the intent unambiguous and the alert no longer fires. Also reorders the impl method block so `secret_store_binding` lands before `secret_store_enabled` per `arbitrary_source_item_ordering`.
