From 8208079ec5feed507455ba1a1b3f0afd8cb3cc81 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 29 Mar 2026 21:47:56 +0000 Subject: [PATCH 1/2] =?UTF-8?q?fix:=20production=20hardening=20=E2=80=94?= =?UTF-8?q?=2020=20code=20quality=20fixes=20across=20Rust=20and=20Python?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Infrastructure: - Add GitHub Actions CI workflow (Rust tests + clippy + Python tests) - Add requirements.txt with pinned dependency versions - Fix Makefile to consistently use python3.11 (was bare python) - Fix Cargo.toml invalid target-cpu profile key (not a valid Cargo setting) - Add .gitignore entries for generated docs artifacts Rust (zero clippy warnings, 70 tests): - Fix all clippy warnings: &PathBufβ†’&Path, map_orβ†’is_some_and, manual range contains, is_multiple_of - Introduce SearchConfig and CandidateParams structs to eliminate too-many-arguments - Fix double unwrap anti-pattern in crossmatch.rs lookup - Consolidate chained .replace() calls in normalize_name - Add --version flag to CLI via clap - Add doc-tests for median, compute_phases, generate_periods Python (32 tests pass): - Replace blanket warnings.filterwarnings("ignore") with specific filters - Add type hints (from __future__ import annotations) to all 4 Python modules - Replace 6 bare except Exception blocks with specific exceptions + logging - Add named constants for magic numbers in validate_candidates.py - Add CSV column validation (checks for time/flux columns) - Fix path traversal risk: use Path.stem / os.path.basename for filenames - Remove global mutable state in deep_analysis.py (findings dict now passed as param) - Sanitize ADQL query inputs in deep_analysis.py Gaia queries - Add input file existence check in analyze_candidates.py https://claude.ai/code/session_01EWyvEJ6ABSWZxKMrTPBdW8 --- .github/workflows/ci.yml | 57 +++++++++++++++++ .gitignore | 4 ++ Cargo.toml | 2 +- Makefile | 8 +-- python/analyze_candidates.py | 24 ++++--- python/deep_analysis.py | 73 ++++++++++++---------- python/download_lightcurves.py | 28 +++++---- python/validate_candidates.py | 91 +++++++++++++++++++-------- requirements.txt | 8 +++ src/bls.rs | 32 +++++++++- src/crossmatch.rs | 9 +-- src/io.rs | 2 +- src/main.rs | 106 +++++++++++++++++-------------- src/validate.rs | 110 +++++++++++++++++++-------------- 14 files changed, 373 insertions(+), 181 deletions(-) create mode 100644 .github/workflows/ci.yml create mode 100644 requirements.txt diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml new file mode 100644 index 0000000..58c0423 --- /dev/null +++ b/.github/workflows/ci.yml @@ -0,0 +1,57 @@ +name: CI + +on: + push: + branches: [main] + pull_request: + branches: [main] + +env: + CARGO_TERM_COLOR: always + +jobs: + rust: + name: Rust Tests & Clippy + runs-on: ubuntu-latest + steps: + -
