We're only looking at the major.minor currently. We need to look
major.minor.patch instead.
This is made slighty problematic non-cpython where the patch version
doesn't match. If major.minor is the same for both the Python version
& the derivation version we default to derivation.version otherwise we
set the pythonVersion to pythonVersion major.minor.0.
This shouldn't be required and I think that these are actually
packaging bugs and not something that poetry2nix should really be
concerned with.
Closes#84
Also use the same source filter for path deps.
The default source filter currently filters:
- Filters gitignore (if it exists, non-recursive)
- Filters pycache/pyc files
- Uses cleanSourceFilter to filter out .git/.hg, .o/.so, editor backup files & nix result symlinks
- Extract utility functions to ./lib.nix
- Extract buildPythonPackage to ./mk-poetry-dep.nix
- Replace some functions with existing builtin functions
- Use lib.partition for python package splitting
- Drop package filtering on the top-level and leave it to pep425.nix
