Previously we randomly encountered issues where the Pypi mirror URLs
wouldn't be correct with packages whos first character is frequently
written in upper case (e.g. SqlAlchemy, MarkupSafe, ...). The Pypi
mirrors are aparently not consistent in the naming of the file locations
which lead to random errors after package version bumps.
By falling back to the API lookup (that we already did for wheels) we
can workaround that situation.
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
