From 322b527281b13a3a509307cd3081b274f4942acf Mon Sep 17 00:00:00 2001 From: carlos-alm <127798846+carlos-alm@users.noreply.github.com> Date: Mon, 9 Mar 2026 01:30:14 -0600 Subject: [PATCH 01/13] feat: unified AST analysis framework with pluggable visitor pattern MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement Phase 3.1 of the architectural refactoring roadmap. Replace 4 independent AST analysis passes (complexity, dataflow, AST-store, CFG) with a shared visitor framework that runs complexity, dataflow, and AST-store visitors in a single DFS walk per file. New framework files: - visitor.js: shared DFS walker with enterNode/exitNode/enterFunction/ exitFunction hooks, per-visitor skipChildren, nesting/scope tracking - engine.js: orchestrates all analyses in one coordinated pass, replaces 4 sequential buildXxx blocks + WASM pre-parse in builder.js - metrics.js: extracted Halstead derived math, LOC, MI from complexity.js - visitor-utils.js: extracted shared helpers from dataflow.js - visitors/complexity-visitor.js: cognitive/cyclomatic/nesting + Halstead - visitors/ast-store-visitor.js: new/throw/await/string/regex extraction - visitors/dataflow-visitor.js: scope stack + define-use chains - tests/unit/visitor.test.js: 9 tests for walker framework Modified modules: - builder.js: 4 sequential buildXxx blocks → single runAnalyses call - complexity.js: delegates walk to complexity visitor - dataflow.js: delegates walk to dataflow visitor - ast.js: delegates walk to ast-store visitor, removed dead code Bug fixes: - Fix Ruby dataflow parity: skip nested return keyword tokens inside return statements (tree-sitter Ruby grammar nests return/return) Hook fixes: - check-dead-exports.sh: exclude public API (index.js) and dynamic import() consumers from dead export detection - check-readme.sh: match ROADMAP.md at any path; allow commit when at least one doc is staged (developer reviewed which docs need updating) Docs: - ROADMAP.md: update 3.1 with completed items and remaining work - BACKLOG.md: add Tier 1h with dynamic import/re-export tracking (ID 71) - CLAUDE.md: add ast-analysis/ to architecture table Impact: 51 functions changed, 47 affected --- .claude/hooks/check-dead-exports.sh | 27 + .claude/hooks/check-readme.sh | 20 +- CLAUDE.md | 1 + docs/roadmap/BACKLOG.md | 8 + docs/roadmap/ROADMAP.md | 50 +- src/ast-analysis/engine.js | 301 ++++++++++ src/ast-analysis/metrics.js | 118 ++++ src/ast-analysis/visitor-utils.js | 176 ++++++ src/ast-analysis/visitor.js | 162 ++++++ .../visitors/ast-store-visitor.js | 150 +++++ .../visitors/complexity-visitor.js | 239 ++++++++ src/ast-analysis/visitors/dataflow-visitor.js | 367 ++++++++++++ src/ast.js | 143 +---- src/builder.js | 95 +-- src/complexity.js | 300 ++-------- src/dataflow.js | 549 +----------------- tests/unit/visitor.test.js | 237 ++++++++ 17 files changed, 1896 insertions(+), 1047 deletions(-) create mode 100644 src/ast-analysis/engine.js create mode 100644 src/ast-analysis/metrics.js create mode 100644 src/ast-analysis/visitor-utils.js create mode 100644 src/ast-analysis/visitor.js create mode 100644 src/ast-analysis/visitors/ast-store-visitor.js create mode 100644 src/ast-analysis/visitors/complexity-visitor.js create mode 100644 src/ast-analysis/visitors/dataflow-visitor.js create mode 100644 tests/unit/visitor.test.js diff --git a/.claude/hooks/check-dead-exports.sh b/.claude/hooks/check-dead-exports.sh index 75ccd509..465385d8 100644 --- a/.claude/hooks/check-dead-exports.sh +++ b/.claude/hooks/check-dead-exports.sh @@ -62,19 +62,46 @@ if [ -z "$FILES_TO_CHECK" ]; then fi # Single Node.js invocation: check all files in one process +# Excludes exports that are re-exported from index.js (public API) or consumed +# via dynamic import() — codegraph's static graph doesn't track those edges.

This is why the engine runs CFG as a separate Mode B pass — the only analysis that can't participate in the shared single-DFS walk. + +Rewrite the CFG algorithm as a node-level visitor that builds basic blocks and edges incrementally via `enterNode`/`exitNode` hooks, tracking block boundaries at branch/loop/return nodes the same way the complexity visitor tracks nesting. This eliminates the last redundant tree traversal during build and lets CFG share the exact same DFS pass as complexity, dataflow, and AST extraction. The statement-level `getStatements` helper and per-language `CFG_RULES.statementTypes` can be replaced by detecting block-terminating node types in `enterNode`. Also simplifies `engine.js` by removing the Mode A/B split and WASM pre-parse special-casing for CFG. + +**Remaining: Derive cyclomatic complexity from CFG.** Once CFG participates in the unified walk, cyclomatic complexity can be derived directly from CFG edge/block counts (`edges - nodes + 2`) rather than independently computed by the complexity visitor. This creates a single source of truth for control flow metrics and eliminates redundant computation. Can also be done as a simpler SQL-only approach against stored `cfg_blocks`/`cfg_edges` tables (see backlog ID 45). -**Affected files:** `src/complexity.js`, `src/cfg.js`, `src/dataflow.js`, `src/ast.js` -> split into `src/ast-analysis/` +**Affected files:** `src/complexity.js`, `src/cfg.js`, `src/dataflow.js`, `src/ast.js` → split into `src/ast-analysis/` ### 3.2 -- Command/Query Separation ★ Critical 🔄 diff --git a/src/ast-analysis/engine.js b/src/ast-analysis/engine.js new file mode 100644 index 00000000..f10170a5 --- /dev/null +++ b/src/ast-analysis/engine.js @@ -0,0 +1,301 @@ +/** + * Unified AST analysis engine — orchestrates all analysis passes in one file-iteration loop. + * + * Replaces the 4 sequential buildXxx calls in builder.js with a single coordinated pass: + * - AST node extraction (calls, new, string, regex, throw, await) + * - Complexity metrics (cognitive, cyclomatic, nesting, Halstead, MI) + * - CFG construction (basic blocks + edges) + * - Dataflow analysis (define-use chains, arg flows, mutations) + * + * Two modes: + * Mode A (node-level visitor): AST + complexity + dataflow — single DFS per file + * Mode B (statement-level): CFG keeps its own traversal via buildFunctionCFG + * + * Optimization strategy: for files with WASM trees, run all applicable visitors + * in a single walkWithVisitors call, then store results in the format that the + * existing buildXxx functions expect as pre-computed data.

The CFG visitor rewrite ([#392](https://github.com/optave/codegraph/pull/392)) eliminated the Mode A/B split, replaced the 813-line `buildFunctionCFG` with a node-level visitor, and derives cyclomatic complexity directly from CFG structure (`E - N + 2`). `cfg.js` reduced from 1,242 → 518 lines. ``` src/ @@ -577,6 +577,7 @@ src/ visitor-utils.js # Shared helpers (functionName, extractParams, etc.) visitors/ complexity-visitor.js # Cognitive/cyclomatic/nesting + Halstead + cfg-visitor.js # Basic-block + edge construction via DFS hooks ast-store-visitor.js # new/throw/await/string/regex extraction dataflow-visitor.js # Scope stack + define-use chains shared.js # findFunctionNode, rule factories, ext mapping @@ -591,76 +592,71 @@ src/ - ✅ `builder.js` → single `runAnalyses` call replaces 4 sequential blocks + WASM pre-parse - ✅ Extracted pure computations to `metrics.js` (Halstead derived math, LOC, MI) - ✅ Extracted shared helpers to `visitor-utils.js` (from dataflow.js) -- 🔲 **CFG visitor rewrite** (see below) - -**Remaining: CFG visitor rewrite.** `buildFunctionCFG` (813 lines) uses a statement-level traversal (`getStatements` + `processStatement` with `loopStack`, `labelMap`, `blockIndex`) that is fundamentally incompatible with the node-level DFS used by `walkWithVisitors`. This is why the engine runs CFG as a separate Mode B pass — the only analysis that can't participate in the shared single-DFS walk. - -Rewrite the CFG algorithm as a node-level visitor that builds basic blocks and edges incrementally via `enterNode`/`exitNode` hooks, tracking block boundaries at branch/loop/return nodes the same way the complexity visitor tracks nesting. This eliminates the last redundant tree traversal during build and lets CFG share the exact same DFS pass as complexity, dataflow, and AST extraction. The statement-level `getStatements` helper and per-language `CFG_RULES.statementTypes` can be replaced by detecting block-terminating node types in `enterNode`. Also simplifies `engine.js` by removing the Mode A/B split and WASM pre-parse special-casing for CFG. - -**Remaining: Derive cyclomatic complexity from CFG.** Once CFG participates in the unified walk, cyclomatic complexity can be derived directly from CFG edge/block counts (`edges - nodes + 2`) rather than independently computed by the complexity visitor. This creates a single source of truth for control flow metrics and eliminates redundant computation. Can also be done as a simpler SQL-only approach against stored `cfg_blocks`/`cfg_edges` tables (see backlog ID 45). +- ✅ CFG visitor rewrite — node-level DFS visitor replaces statement-level `buildFunctionCFG`, Mode A/B split eliminated ([#392](https://github.com/optave/codegraph/pull/392)) +- ✅ Cyclomatic complexity derived from CFG (`E - N + 2`) — single source of truth for control flow metrics ([#392](https://github.com/optave/codegraph/pull/392)) **Affected files:** `src/complexity.js`, `src/cfg.js`, `src/dataflow.js`, `src/ast.js` → split into `src/ast-analysis/` -### 3.2 -- Command/Query Separation ★ Critical 🔄 - -> **v3.1.1 progress:** CLI display wrappers for all query commands extracted to `queries-cli.js` (866 lines, 15 functions).
