rez-pip 0.3.2

Modern rez-pip

rez-pip

Modern rez-pip implementation. Very WIP.

TODOs

• Install packages without using pip
• Specify Python version to use
• Better logs and CLI experience
  • Use logging
  • Progress bars for download?
• Confirm that Python 2 is supported
  • It is not...
• Confirm that the theory works as expected
• Windows support
• Hook into rez
  • Install each package in a different --target
  • Create rez package
  • Copy distribution files to rez package.
  • Make it available as a rez plugin/sub-command
  • Discover Python package using rez and use that when available. I think it's still fine to support non-rezified Python interpreters though.
  • Only download+convert package if it's not already in the rez repositories.
  • etc
• Accept multiple package names as input
• Accept requirements files as input
• Accept wheel files as input
• Properly support platform tags (wheels tags) so that GLIBC is respected, min macOS is also supported.
• Correctly handle Requires-Python metadata.
• Review all TODOs in the code.
• What whould we do with rez.system and rez.vendor.version?
• Gather a list of problematic packages from GitHub and test against them.
• Go through GitHub issues and summarize what needs to be covered by the new rez-pip.
• Support abi3 wheels (to avoid having to re-install C extensions for every python version).
  • https://docs.python.org/3/c-api/stable.html
  • https://peps.python.org/pep-0425/
  • Basically a tag like 'cp36-abi3-manylinux_2_24_x86_64' means that it is compatible with Python 3.6+ and doesn't need to be recompiled for newer python versions.

Tips

For now, it can be run like this:

rez-pip2 pytest

By default, rez packages will be released. You can choose a different path by passing the --install-path argument to rez-pip2.
