Eli Peter	f96a89e7c1	Feat/full cfg (#30) ... * feat: Enhance control flow analysis with function summaries and taint analysis * feat: Update taint analysis to utilize function summaries for enhanced tracking * Refactor `walk.rs` batch processing and override handling: - Renamed `Batcher` to `BatchSender` for clarity. - Added `BatchSender::new` constructor for cleaner initialization. - Simplified batch size management in `BatchSender`. - Extracted `build_overrides` function for reusable override construction. - Improved error handling and validation in override building. - Enhanced performance with directory and file type filtering in `walk`. * Improve logging and streamline directory walk process: - Added detailed `tracing` logs for debugging batch flushes, override construction, and walk initialization/completion. - Optimized and simplified `filter_entry` logic for directory and file type filters. - Improved metadata checks and max file size enforcement during the scan. * Refactor and optimize taint tracking, label rules, and directory walk process: - Replaced `DefaultHasher` with `blake3::Hasher` for improved taint hashing. - Enhanced sorting and hashing logic in `taint.rs` for consistency and efficiency. - Removed unused `set_hash` function and redundant imports across files. - Improved batch sender logic in `walk.rs`, renaming key components for clarity. - Unified `spawn_senders` and `spawn_file_walker` with thread handling and channel tuple return. - Expanded label rules with additional matchers for sources, sanitizers, and sinks. - Deprecated `dump_cfg` and specific logging utilities in `cfg.rs` for code cleanup. * fix: fixed let chains error in walk.rs * fix: updated dependencies * fix: updated dependencies * chore: Remove standard error in scan.rs * feat: Introduce function summaries for enhanced taint and control flow analysis * feat: Enhance taint analysis with interop support and function summaries * feat: Add configuration analysis module and enhance matcher rules * feat: Add arity column to function_summaries and handle schema migration * fix: fixed clippy &PathBuf warnings * chore: Update dependencies and versioning in Cargo files * docs: Update README to enhance clarity and detail on features and analysis modes * chore: Update CHANGELOG for version 0.2.0 with new features, changes, and fixes * docs: Update SECURITY.md to clarify version support status --------- Co-authored-by: elipeter <eli.peter@es.fcm.travel>	2026-02-24 23:44:07 -05:00
Eli Peter	3c21efba75	Added experimental control flow analysis and syntax classification for rust lang (#22) ... * Introduce control flow graph (CFG) support: - Added `cfg.rs` with CFG generation and analysis utilities. - Integrated `petgraph` library for graph-based computations. - Updated `ast.rs` to utilize CFG for function analysis. - Modified `Cargo.toml` and `Cargo.lock` to include new dependencies. - Improved static analysis with taint tracking through CFG paths. * feat: enhance control flow analysis with taint tracking and node labeling * feat: improve control flow graph with enhanced node handling and new tests * Remove unnecessary reference marker in `byte_offset_to_point` comment. * Remove unnecessary reference marker in `byte_offset_to_point` comment. * Refactor `ast.rs` for performance and clarity; enhance `cfg.rs` with recursive CFG generation and improved classification logic for AST analysis. * Refactor CFG and taint tracking logic: - Enhanced `cfg.rs` with inline helper function `text_of` for cleaner UTF-8 handling in AST nodes. - Expanded `labels.rs` rules with detailed `Sources`, `Sanitizers`, and `Sinks` for improved classification. - Refined `push_node` to handle method call expressions with object-function pairing. - Simplified code handling in trivia skipping and debug-only logic. * Enhance `cfg.rs` with `first_call_ident` helper and improve identifier extraction logic in `push_node`. * Add targeted CFG taint-tracking tests to enhance analysis coverage. * Enhance CFG generation with loop expression handling and improve taint tracking logic. Add new sanitization example in `examples/sanitize/example.rs`. * Update README with installation instructions for Cargo and GitHub releases. * Expand taint-tracking with precise `def-use` computation and enhance `labels.rs` for detailed classification. Extend `examples/sanitize` with realistic scenarios demonstrating new rules. * Refactor `labels.rs`: - Removed redundant `LabelRule` entries for cleaner rule definitions. - Adjusted matching logic to prioritize suffix and prefix matches effectively. * Refactor `labels.rs`: - Removed redundant `LabelRule` entries for cleaner rule definitions. - Adjusted matching logic to prioritize suffix and prefix matches effectively. * Add test for taint tracking with multiple sources in `cfg.rs`. * Add `function_summaries` table and implement summary upsert/load methods. Refactor to handle summary storage and retrieval efficiently, with placeholder clean/drop logic. * refactor: split `labels.rs` into modular structure with language-specific files * refactor: split `labels.rs` into modular structure with language-specific files * refactor: clean up SQL table definitions in `database.rs` for better readability * refactor: simplify CFG structure by removing lifetime parameters and enhancing taint metadata handling * refactor: update TODO comments in `cfg.rs` to clarify future enhancements for cap labels and function details * refactor: remove redundant header from README.md for improved clarity * feat: add PHF-based syntax classifiers and Kind enum for efficient syntax mapping across languages * feat: introduce analysis modes for enhanced scanner configuration and diagnostics * feat: define Kind enum for syntax classification in control flow analysis * feat: bump version to 0.2.0-alpha and update CHANGELOG for new features and fixes * refactor: clean up imports and formatting in AST and CFG modules for improved readability * refactor: simplify function signatures and improve code readability in CFG and module files * fix: correct rayon_thread_stack_size comment to reflect actual value of 8 MiB * refactor: update string formatting in clean and project modules for consistency * refactor: fix indentation in clean.rs for improved readability --------- Co-authored-by: elipeter <eli.peter@es.fcm.travel>	2025-06-28 17:36:14 +02:00
