From e5075e34134453a7816f0b5a2b3522af14932762 Mon Sep 17 00:00:00 2001 From: Sascha <18143567+SaschaOnTour@users.noreply.github.com> Date: Thu, 4 Jun 2026 22:26:03 +0200 Subject: [PATCH 01/52] refactor(shared): consolidate shared analyzer concepts into adapters/shared Move FileVisitor/visit_all_files, DeclaredFunction, ProjectScope (with ScopeCollector, helpers, and tests) and the test-reference collector into adapters/shared, and re-point every importer. This removes the analyzer-to-analyzer reach-ins (srp->dry, tq->dry, tq->iosp, srp->iosp): each dimension now imports the shared concept instead of another analyzer's internals.

Collapse `[srp].file_length_baseline` and `file_length_ceiling` (plus the `[tests]` equivalents) into a single `file_length` threshold (default 300); a file is flagged when its production lines strictly exceed it. `length_score` is now the `production_lines / file_length` ratio, reported as metadata only. BREAKING: the `file_length_baseline` / `file_length_ceiling` config keys (under both [srp] and [tests]) are removed in favour of `file_length`. --- rustqual.toml | 5 +- src/adapters/analyzers/srp/mod.rs | 4 +- src/adapters/analyzers/srp/module.rs | 57 +++++------- .../srp/tests/cohesion/lcom4_and_collector.rs | 2 +- .../analyzers/srp/tests/module/clusters.rs | 92 ++++++++++--------- .../srp/tests/module/scoring_and_analysis.rs | 38 ++++---- src/adapters/analyzers/srp/tests/root.rs | 8 +- src/adapters/config/init.rs | 12 +-- src/adapters/config/sections.rs | 18 ++-- src/adapters/config/tests/sections.rs | 14 +-- src/adapters/report/ai/details.rs | 5 +- src/app/metrics.rs | 13 +-- 12 files changed, 121 insertions(+), 147 deletions(-) diff --git a/rustqual.toml b/rustqual.toml index 18ebf47b..f8a4d015 100644 --- a/rustqual.toml +++ b/rustqual.toml @@ -104,9 +104,8 @@ enabled = true # and [srp].

A target is named by its config field (metric) or rule name (boolean): metric targets require a mandatory pin value (a value-less threshold suppression would be blind forever) and a reason, boolean targets take no value. The target vocabulary lives in domain::suppression_target (target_kind / target_names) as the single source of truth that the per-dimension marking code will consume. A single classify_qual_allow drives both parse_qual_allow and detect_invalid_qual_allow so they can never diverge; unknown / malformed targets surface as ORPHAN_SUPPRESSION whose reason lists the valid targets (this is what stops an agent inventing a non-existent target like `srp_params`). Suppression gains an optional `target`; bare allow(dim) is unchanged and marking does not yet consume the target — that lands per dimension next. --- src/adapters/suppression/qual_allow.rs | 276 +++++++++++++----- src/adapters/suppression/tests/mod.rs | 1 + src/adapters/suppression/tests/qual_allow.rs | 18 +- src/adapters/suppression/tests/targeted.rs | 95 ++++++ src/app/tests/architecture.rs | 1 + src/app/tests/metrics/counters.rs | 1 + src/app/tests/metrics/mod.rs | 1 + src/app/tests/metrics/srp_suppression.rs | 1 + src/app/tests/metrics/suppression.rs | 1 + src/app/tests/mod.rs | 1 + src/app/tests/pipeline.rs | 6 + src/app/tests/warnings/flag_application.rs | 1 + src/app/tests/warnings/mod.rs | 1 + .../warnings/orphan_basics_and_suppression.rs | 3 + .../tests/warnings/orphan_dry_and_disabled.rs | 4 + .../tests/warnings/orphan_mod_internals.rs | 1 + .../tests/warnings/orphan_module_tq_arch.rs | 4 + src/app/tests/warnings/orphan_support.rs | 2 + src/domain/mod.rs | 2 + src/domain/suppression.rs | 19 +- src/domain/suppression_target.rs | 111 +++++++ src/domain/tests/suppression.rs | 3 + src/ports/tests/suppression_parser.rs | 1 + 23 files changed, 480 insertions(+), 74 deletions(-) create mode 100644 src/adapters/suppression/tests/targeted.rs create mode 100644 src/domain/suppression_target.rs diff --git a/src/adapters/suppression/qual_allow.rs b/src/adapters/suppression/qual_allow.rs index 8bfb00ad..6edbb152 100644 --- a/src/adapters/suppression/qual_allow.rs +++ b/src/adapters/suppression/qual_allow.rs @@ -1,6 +1,7 @@ // Re-export Domain types so existing `crate::findings::{Dimension, Suppression}` // call sites keep working.

Metric pins suppress only while the value is <= the pin and re-fire above it, and a file_length pin can never hide a co-occurring cohesion finding (each active module component must be covered independently). Adds Suppression::suppresses() as the matching primitive and extracts the SRP marking into app/srp_suppressions.rs (mirroring dry_suppressions, keeping metrics.rs under the file-length cap). Existing blanket allow(srp) markers are unchanged. The 10% too-loose-pin orphan and the fix-first finding output land next; both are cross-cutting across every dimension's pins / findings. --- src/app/metrics.rs | 42 ----------- src/app/mod.rs | 1 + src/app/secondary.rs | 5 +- src/app/srp_suppressions.rs | 78 ++++++++++++++++++++ src/app/tests/metrics/mod.rs | 2 + src/app/tests/metrics/srp_suppression.rs | 12 ++- src/app/tests/metrics/srp_targeted.rs | 93 ++++++++++++++++++++++++ src/domain/suppression.rs | 21 ++++++ 8 files changed, 208 insertions(+), 46 deletions(-) create mode 100644 src/app/srp_suppressions.rs create mode 100644 src/app/tests/metrics/srp_targeted.rs diff --git a/src/app/metrics.rs b/src/app/metrics.rs index 3323a3c8..7c318b15 100644 --- a/src/app/metrics.rs +++ b/src/app/metrics.rs @@ -202,48 +202,6 @@ pub(super) fn count_dry_findings( .sum(); } -/// Mark SRP warnings as suppressed based on `// qual:allow(srp)` comments. -/// Operation: iteration + suppression matching via closures (no own calls). -pub(super) fn mark_srp_suppressions( - srp: Option<&mut crate::adapters::analyzers::srp::SrpAnalysis>, - suppression_lines: &std::collections::HashMap>, -) { - let Some(srp) = srp else { return }; - - // Struct suppressions: comment may be several lines above due to #[derive(...)] attributes - // Window width shared with the orphan detector, see - // `app::suppression_windows::SRP_STRUCT_PARAM`. - const SRP_STRUCT_SUPPRESSION_WINDOW: usize = super::suppression_windows::SRP_STRUCT_PARAM; - let srp_dim = crate::findings::Dimension::Srp; - - srp.struct_warnings.iter_mut().for_each(|w| { - if let Some(sups) = suppression_lines.get(&w.file) { - w.suppressed = sups.iter().any(|sup| { - let in_window = - sup.line <= w.line && w.line - sup.line <= SRP_STRUCT_SUPPRESSION_WINDOW; - in_window && sup.covers(srp_dim) - }); - } - }); - - srp.module_warnings.iter_mut().for_each(|w| { - if let Some(sups) = suppression_lines.get(&w.file) { - w.suppressed = sups.iter().any(|sup| sup.covers(srp_dim)); - } - }); - - // Param suppressions: proximity-based like struct warnings (attributes above fn) - srp.param_warnings.iter_mut().for_each(|w| { - if let Some(sups) = suppression_lines.get(&w.file) { - w.suppressed = sups.iter().any(|sup| { - let in_window = - sup.line <= w.line && w.line - sup.line <= SRP_STRUCT_SUPPRESSION_WINDOW; - in_window && sup.covers(srp_dim) - }); - } - }); -} - /// Mark wildcard import warnings as suppressed based on `// qual:allow(dry)` comments. /// Operation: iteration + suppression check, no own calls. pub(super) fn mark_wildcard_suppressions( diff --git a/src/app/mod.rs b/src/app/mod.rs index 1a2f0435..9844b6e0 100644 --- a/src/app/mod.rs +++ b/src/app/mod.rs @@ -17,6 +17,7 @@ pub(crate) mod pipeline; pub(crate) mod projection; pub(crate) mod secondary; pub(crate) mod setup; +pub(crate) mod srp_suppressions; pub(crate) mod structural_metrics; pub(crate) mod suppression_windows; pub(crate) mod tq_metrics; diff --git a/src/app/secondary.rs b/src/app/secondary.rs index 0126ab2f..afcbd318 100644 --- a/src/app/secondary.rs +++ b/src/app/secondary.rs @@ -13,8 +13,9 @@ use super::dry_suppressions; use super::metrics::{ self, apply_parameter_warnings, build_file_call_graph, compute_coupling, compute_srp, count_coupling_warnings, count_dry_findings, count_srp_warnings, mark_coupling_suppressions, - mark_srp_suppressions, run_dry_detection, run_guarded_detection, + run_dry_detection, run_guarded_detection, }; +use super::srp_suppressions::mark_srp_suppressions; use super::structural_metrics::{ compute_structural, count_structural_warnings, mark_structural_suppressions, }; @@ -145,7 +146,7 @@ fn run_srp_pass( let file_call_graph = build_file_call_graph(ctx.all_results); let mut srp = compute_srp(ctx.parsed, ctx.config, &file_call_graph); apply_parameter_warnings(ctx.all_results, srp.as_mut(), &ctx.config.srp); - mark_srp_suppressions(srp.as_mut(), ctx.suppression_lines); + mark_srp_suppressions(srp.as_mut(), ctx.suppression_lines, &ctx.config.srp); count_srp_warnings(srp.as_ref(), summary); srp } diff --git a/src/app/srp_suppressions.rs b/src/app/srp_suppressions.rs new file mode 100644 index 00000000..f9ed9af8 --- /dev/null +++ b/src/app/srp_suppressions.rs @@ -0,0 +1,78 @@ +//!

The previous fix seeded all ignored (visit_*) functions as "implicitly tested" — a blanket assumption baked into the analyzer. Replace that with real edges: for each visitor type T, record the helper methods its syn::Visit overrides call, and at each drive-site (x.visit_block(..), syn::visit::visit_*(&mut x, ..), visit_all_files(.., &mut x)) resolve the driven type locally and add driver_fn → helpers(T) edges. Testedness now flows only when a test actually drives the visitor; an undriven visitor stays untested. Drops the is_ignored_function seed entirely. Isolated change — visit_* remains in ignore_functions, so complexity/SRP exemptions are unaffected.

Fix: non-mechanical trait methods now act as BRIDGES — their field footprint (direct accesses + one-level self-call expansion) unions the inherent methods they tie together, WITHOUT being counted as responsibility nodes. This is monotonic (only merges components, never splits), so it can only clear false positives, never manufacture new ones. Mechanical traits (Display/Debug/From/Into/Serialize/PartialEq/Hash/Default/ Clone/…) stay fully excluded: their methods touch all fields by rote and would mask genuine god-structs. Stateless trait methods (e.g. reporter render_*) touch disjoint fields, so they bridge nothing and reporters stay unflagged.

dogfood complexity MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove the blanket "visit_*" entry from ignore_functions — the single biggest hidden suppression in the project (133 methods got a total free pass on every dimension, far beyond its stated call-graph rationale). The call-graph dimensions (TQ-003, dead-code) already exempt trait impls structurally, and the dispatch-edge fix handles their reachability, so the name-ignore was redundant there; only its (illegitimate) complexity/IOSP free pass remained. Refactor every fat visitor to per-node category dispatch so it passes rustqual own rules: - Normalizer::visit_expr (cyclo 53, 246 ln) + visit_pat → category handlers - BodyVisitor::visit_expr (cyclo 48, 297 ln, IOSP violation) → free walk_* functions (walk steps, not struct responsibilities — keeps the metrics-visitor SRP footprint at its pre-refactor size) - WildcardCollector::visit_item_use, MutationChecker::visit_expr, CallTargetCollector::visit_field → extracted decision helpers Call-detection predicates are hidden in closures (lenient mode) to keep the dispatch arms Operations, not IOSP Violations. Also refine bridge-only cohesion: a bridge now ties in the methods it directly calls (not only those sharing its field footprint), so a pure-delegation dispatch arm that touches no field still coheres with the walk. main/run stay ignored (handled next).

decompose run() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The composition root run() in lib.rs mixed arg parsing, mode dispatch, and the analysis pipeline (cyclo 15, 86 lines, IOSP violation) — which is why it was name-ignored. Decompose it into phase operations (parse_cli_args, try_preconfig_modes, run_configured, try_postconfig_modes, run_full_analysis, collect_and_analyze, report_analysis, handle_baseline_and_compare); run() now orchestrates with early-exit branches in unwrap_or_else closures so it stays a clean Integration. main passes on its own. Fix the layer_rule test run() helper SRP_PARAMS (6 params) with an Externals parameter object. ignore_functions is now [] — every function in rustqual is analyzed by its own rules.

It was a blunt instrument that hid functions from EVERY dimension; with the visitor-dispatch and bridge fixes in place, nothing in rustqual needs it. A rustqual.toml that still sets ignore_functions will now fail to parse (deny_unknown_fields) — remove the key; use // qual:allow, // qual:api, // qual:test_helper, or exclude_files instead. Removes the Config field, is_ignored_function, the compiled glob cache, and all consume sites (iosp classification, TQ-003 untested filter, DRY-002 dead-code exclusion) plus the init templates and tests. Also: compute_lcom4 now unions methods connected by a self.other() call, matching canonical LCOM4 (which joins methods sharing a field OR calling one another). This was a latent gap surfaced when removing the is_ignored_function field-touch left Analy zer falsely split; the fix is general and monotonic. Self-analysis 100%/0; 1894 tests green; clippy clean. --- rustqual.toml | 11 --- src/adapters/analyzers/dry/dead_code.rs | 26 ++---- src/adapters/analyzers/dry/tests/dead_code.rs | 89 ------------------- src/adapters/analyzers/iosp/mod.rs | 35 +++----- .../iosp/tests/root/classify_basics.rs | 21 ----- src/adapters/analyzers/srp/cohesion.rs | 15 ++++ src/adapters/analyzers/tq/mod.rs | 1 - src/adapters/analyzers/tq/tests/untested.rs | 33 +++---- src/adapters/analyzers/tq/untested.rs | 3 - src/adapters/config/init.rs | 12 --- src/adapters/config/mod.rs | 17 ---- src/adapters/config/tests/init.rs | 2 +- src/adapters/config/tests/root.rs | 55 +----------- src/app/metrics.rs | 1 - 14 files changed, 47 insertions(+), 274 deletions(-) diff --git a/rustqual.toml b/rustqual.toml index e41ea2cf..c09eed6a 100644 --- a/rustqual.toml +++ b/rustqual.toml @@ -3,17 +3,6 @@ # Place this file in your project root. -# Function names (or patterns with trailing *) to exclude from analysis. -# - `main` / `run` — Composition-Root-Dispatcher, IOSP-Ignore -# (Top-Level-Entrypoints mischen zwangsläufig Branching + Delegation). -# - `visit_*` — syn-Visitor-Methoden mit fester extern-Signatur.

The `ignore_functions` option is removed. + +### Removed +- **BREAKING: the `ignore_functions` config option is gone.** It excluded + matching functions from *every* dimension — a far broader effect than its + stated purpose (papering over call-graph blindness for trait-dispatched + methods), and the single largest hidden suppression in a project. A + `rustqual.toml` that still sets `ignore_functions` now fails to parse + (`deny_unknown_fields`). **Migration:** delete the key. For the rare function + that genuinely cannot be analyzed, use `// qual:allow()`, `// qual:api`, + `// qual:test_helper`, or `exclude_files` instead. + +### Changed +- **TQ-003 (untested) now models syn-visitor dispatch as real call-graph + edges.** Previously a visitor's `visit_*` overrides and their helper methods + looked unreachable from tests (the static call graph can't follow syn's + `visit_block → visit_expr` dispatch), and the gap was hidden by seeding every + ignored function as "implicitly tested." That blanket assumption is replaced: + for each visitor type the helper methods its overrides call are recorded, and + at each drive-site (`x.visit_block(..)`, `syn::visit::visit_*(&mut x, ..)`, + `visit_all_files(.., &mut x)`) the driven type is resolved locally and + `driver → helpers` edges are added. Testedness now flows only when a test + actually drives the visitor — an undriven visitor is still flagged. +- **SRP cohesion (LCOM4) is more faithful to the canonical metric.** Two fixes, + both monotonic (they only *merge* components, never create new findings): + - Non-mechanical trait methods (e.g. a `syn::Visit` impl) now *bridge* the + inherent methods they tie together — via their field footprint **and** the + methods they call — without being counted as responsibility nodes. This + stops a struct whose core logic lives in a behavior trait (visitor, walker) + from fragmenting into false god-structs. Mechanical traits + (`Display`/`Debug`/`From`/`Serialize`/`PartialEq`/`Hash`/`Default`/`Clone`/…) + stay excluded so they can't mask genuine god-structs. + - Methods connected by a `self.other()` call are now unioned, matching the + canonical LCOM4 definition (methods cohere when they share a field **or** + call one another). + +### Internal +- `main`, `run`, and all `visit_*` methods are no longer name-ignored; every + function in rustqual is analyzed by its own rules. The fat AST visitors + (`Normalizer`, `BodyVisitor`, and several collectors) were refactored to + per-node category dispatch, and the composition root `run()` was decomposed + into phase operations — so rustqual dogfoods its own complexity, IOSP, and + cohesion rules on its own visitor code. + ## [1.4.2] - 2026-06-04 Patch release: a false-positive fix found while applying 1.4.1.

It would silence EVERY finding of that dimension — too blunt — so it must name a target: // qual:allow(srp, god_struct), // qual:allow(complexity, max_cyclomatic=20), etc. iosp (no targets) keeps its bare form. Multi-dimension blanket markers (allow(a, b)) are likewise gone — use one marker per dimension.

Type redesign (R1): `domain::SuppressionTarget` is now a sum type (`Metric { name, pin } | Boolean { name }`) so the "metric ⇒ pin, boolean ⇒ no pin" invariant is unrepresentable otherwise; `suppresses()` matches the variant directly. `name()`/`pin()` accessors replace the public fields. Orphan-detector bugs: - B1: `srp_finding_targets` now emits the `file_length` / `max_independent_ clusters` position only for the component that actually fired (length_score > 1.0 / clusters > max), mirroring `module_warning_suppressed`. A pin on the inactive component was escaping stale detection and mis-firing as too-loose. - B2: a targeted coupling marker (max_fan_*/instability/sdp) is module-global with no line-anchored position, so `is_verifiable` now treats it as unverifiable instead of false-flagging it when a structural coupling finding coexists in the file. - B3: the `magic_numbers` position anchors at the function line, not the literal's line, so a valid `allow(complexity, magic_numbers)` marker placed above the function is no longer reported stale. Tests (T1): +12 cases — cluster/param too-loose, headroom boundary (`>` vs `>=`), config-driven `pin_headroom`, largest-covered-value fold, and arch/dry/ tq targeted-orphan kind matching. The orphan target tests were split into `orphan_targeting` + `orphan_too_loose` (+ shared `orphan_target_helpers`) to stay under the SRP file-length cap; `orphans_cfg` trimmed to ≤5 params.

With targeted coupling markers also skipped by the orphan detector (module-global), the hidden warning was not even replaced by an orphan — a silent suppression. Structural checks are not in the suppression-target vocabulary, so only a blanket marker may silence them: `in_window && sup.target.is_none() && sup.covers(dim)`. This mirrors the orphan detector, where structural positions carry `target: None` and match blanket markers only. Since blanket SRP/Coupling markers are rejected by the parser ("the flip"), a structural finding is effectively unsuppressible — the honest consequence of the flip, now reflected consistently on both the marking and orphan sides.

Each structural check now has its own boolean suppression target named by its lowercased code — `oi`/`sit`/`deh`/`iet` (coupling), `btc`/`slm`/`nms` (SRP): // qual:allow(coupling, oi) reason: "orphan rules force this impl away" - `StructuralWarningKind::target_name` + the shared `target_name_for_code` (single source for the code→target map). - Vocabulary: the seven codes added to `target_kind`/`target_names` (Srp, Coupling) — so `--explain allow` lists them and the parser accepts them. - Marking routes through `suppresses()` (a targeted marker silences only its own kind; a metric coupling pin never silences a structural finding). - Orphan collector tags structural positions with their target; `is_verifiable` now skips only *module-global* coupling targets (max_fan_*/instability/sdp) — structural coupling targets are line-anchored and verified normally (`is_module_global_coupling`). - Tests: targeted structural marker silences its own kind / not another; orphan matches its kind / stale on the wrong kind.
