Description

This story is to use the syntax from python requirements[0] files to specify which packages should be synced. This story does NOT include directly uploading a requirements.txt (though that feature could be discussed in another issue)

Note:
It doesn't make sense for Pulp to support all of the possible syntaxes in a requirements file (like specifying a local file).

Background:

At the time of writing, pulp-python only supports a whitelist of project names, but this whitelist should become more granular and flexible.

Specifiers [1][2]

It would be ideal to support multiple levels of filtering:

  • project name
  • version specifiers (including gt, lt, range)
  • specific python distributions (specified by hash) [3]

Allowing users to specify python distributions by hashes [3] will significantly improve 2 of our use cases:

  • reproducible, deterministic builds
  • improved security

Related Ideas:

These ideas are related to the implementation of this story, but if they are accepted, they should be filed separately.

  1. Create a whitelist from a requirements.txt
  2. Create a whitelist from a Pipfile (pipenv)
  3. Create a whitelist from a Pipfile.lock (pipenv)
  4. Create a whitelist from a python toml file
