Walkthrough

This update introduces a large set of new static analysis rules for C, C++, C#, Go, Java, JavaScript, and HTML, targeting security vulnerabilities such as hard-coded secrets, cryptographic weaknesses, insecure cookie flags, and race conditions. It also removes several outdated or redundant rules. New documentation, licensing, and contribution files are added, and a Python-based rule database tool is introduced. The package.json scripts and dependencies are updated.

Poem

In the garden of code, new rules now bloom,
Guarding secrets, cookies, and cryptographic doom.
With Python scripts and docs so neat,
Security’s strengthened, vulnerabilities beat!
Hop, hop, hooray—let’s review with delight,
For safer code is now in sight!

Impact Analysis

Updated static analysis rule set: new rules added and obsolete rules removed

⚠️ High 🔄 Impacts behavior 🔒Impacts security

A comprehensive set of new security rules has been added across C, C++, C#, Go, Java, HTML, and JavaScript (e.g. TOCTOU checks, insecure‐hash detectors, null‐pointer, format‐string, world-writable file, JWT misuses, AngularJS SCE, plaintext HTTP links, etc.), while many older rules have been deleted (e.g. gets(), memset(), scanf(), strtok(), BinaryFormatter, Jwt-none, unsafe gRPC, insecure template types, manual sanitization, wildcard postMessage, JWT no-verify). This changes the tool’s output: new warnings will appear for the added checks, and warnings from removed rules will no longer be reported.

Verify the correctness of each new rule’s AST patterns and metadata; confirm the rationale for rule removals aligns with updated security policy and doesn’t introduce blind spots.

Run the full rule set on representative codebases and compare outputs before/after: ensure new rules fire on intended patterns without false positives, and that deleted rules no longer generate alerts.

Introduce interactive RuleDatabase CLI with SQLite backend

📢 Medium 🔗 Impacts API 🔄 Impacts behavior

A new Python module (rule_db.py) and associated CLI commands have been added, enabling users to initialize an SQLite database of AST-Grep rules, load rule metadata, execute arbitrary SQL queries, perform full-text searches, and view statistics and language filters. This provides an interactive interface for exploring and exporting rule data.

Review the database schema (table definitions, indexes, FTS5 setup) and SQL handling for injection risks; ensure CLI option parsing and error messages are clear and robust.

Test each CLI command (init, query, search, stats, languages, lang) with valid and invalid inputs; verify correct data loading from a rules directory and accurate query/search results in table/JSON/CSV formats.
