Python

[codyopel]

Meta issue for tracking, planning, and breakage.

Priority 1

• Rewrite wrapPython

Priority 2

• Document bootstrapping buildPythonPackage
• Fix stage 1 prefixName
• Fix hardcoded PYTHONPATH definitions, always assume path is empty (e.g. ${PYTHONPATH:+:}$PYTHONPATH)
• Symlink setuptools' dependencies into the vendor directory to reuse the vendor import paths and prevent propagating setuptools' dependencies
• Stage 2 setuptools breaks namespaced imports on Python 2 (possibly other issues as well, also possibly applicable to Python 3). Currently we reuse the Stage 1 derivation.
  Update: This is an upstream setuptools bug when installing setuptools from a wheel to a wheel.
• Don't overwrite pre/post phases in buildPythonPackage, append the pre/post phases defined in buildPythonPackage.
• Possibly rewrite fetchPyPi to use python instead of jq
• Remove with pkgs.lib from python-packages.nix, inherit lib normally
• Check for orphaned packages
• Finish moving packages out of python-packages.nix
• Come up with a solution for removing propagation
• Work on an alternative for PYTHONPATH that isn't susceptible to Python 2 & 3 collisions. In conjunction with wrapPython. rewrite build-python-package to not use PYTHONPATH #64
• Install wheel files to a unique output
• review and port deterministic build patches
• Clean up check phases and functionality
• rename configureFlags in buildPythonPackage
• If possible, only propagate setuptools where necessary (e.g. namespaced packages require setuptools at runtime)
