…ure buildout for Python 3 - Add six library for Python 2/3 compatibility - Update print statements to use print() function syntax - Configure buildout.cfg for Python 3 compatibility - Update P8_UPGRADE_GUIDE.md references - Add PYTHONPATH to instance environment - Add python-buildout section for Python 3
- Add pyproject.toml with Python 3.10+ support - Configure UV dependency groups (replacing deprecated dev-dependencies) - Add six library for Python 2/3 compatibility - Simplify setup.py to defer to pyproject.toml - Successfully sync 248+ packages with UV (except Pillow build issue) Note: Pillow build issue persists due to missing zlib headers in build environment. This demonstrates the pyproject.toml + UV approach works for modern Python 3 packaging.
- Add [tool.uv] section with override-dependencies - Override Pillow>=10.0.0 to use binary wheels instead of source build - Products.PortalTransforms pins old Pillow version requiring zlib headers - This fix allows UV sync to complete successfully on Windows
- Update README.md with UV quick start instructions - Add etc/zope.conf for Zope configuration - Add etc/wsgi.ini for WSGI server configuration - Add run_instance.py for launching SENAITE with UV Note: SENAITE still requires Archetypes->Dexterity migration for full Python 3 support
- Add Python 3 classifiers - Remove deprecated namespace_packages (handled by pyproject.toml) - Clean up imports order
- Document all completed work and current status - Detail the Archetypes blocker and migration path - Provide technical summary for contributors - Complete audit trail of Python 3 modernization effort
- Detailed technical assessment of Archetypes → Dexterity migration - Scope analysis: 219 files affected, 100+ content types - Implementation roadmap with phases and timelines - Risk assessment and mitigation strategies - Alternative approaches evaluation - Resource requirements and success criteria
- Improve markdown formatting for better readability - Add proper line breaks and table formatting - Final review of documentation completeness
