From a0ac49bc33f194b934004a5c2beb3c70fb54f8e9 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 26 Jan 2026 20:08:02 +0000 Subject: [PATCH] Fix remaining production readiness issues 1. Convert pipeline.py to native async aiohttp - Replace requests.get() with aiohttp.ClientSession - Remove run_in_executor workaround - Now fully async for _fetch_from_arxiv and _fetch_from_crossref 2. Add comprehensive CLI tests (33 tests) - Test all major commands: search, download, validate, etc. - Test subcommand groups: auto, library, evolve - Test help text, argument validation, error handling - Uses Click CliRunner with mock API keys 3. Document protobuf CVE-2026-0994 - Add detailed section explaining the vulnerability - Document why it's low risk for this CLI tool - Provide monitoring instructions for when fix is available - Include remediation plan https://claude.ai/code/session_019XEBDoEmdKV4wzfvpk5QCy --- PRODUCTION_READINESS_REVIEW.md | 63 ++++- quantcoder/autonomous/pipeline.py | 25 +- tests/test_cli.py | 410 ++++++++++++++++++++++++++++++ 3 files changed, 484 insertions(+), 14 deletions(-) create mode 100644 tests/test_cli.py diff --git a/PRODUCTION_READINESS_REVIEW.md b/PRODUCTION_READINESS_REVIEW.md index eeef9e9..829a0e0 100644 --- a/PRODUCTION_READINESS_REVIEW.md +++ b/PRODUCTION_READINESS_REVIEW.md @@ -13,11 +13,13 @@ This application is ready for commercial release as a self-hosted Docker image.
