Hello all,
I was discussing [1] about porting oci-cli to ports tree. It is a python package, that
should not be a big deal, though, investigating a bit more "requires" field in
setup.py [2], I noticed it depends on specific python libraries, for example oci-sdk
2.10.5, configparser 3.5.0 or six 1.11.0.
What is the official FreeBSD packaging policy with regards to such python
packages? What about installing something in a virtualenv?

Let me know if you need anything else from me.
Thank you,
Alessandro

Hi Allesandro
I recently expanded on the existing Python Policy with regard to
dependencies, including what to do with == dependencies.
https://wiki.freebsd.org/Python/PortsPolicy#Dependencies
The tldr is, == dependencies are not suitable for "packaging", they are
suitable for "deployments".
To port these packages, they should be updated to >= counterparts (patch
the setup.py, or source file for those dependencies).
Unfortunately this requires additional QA to do properly, as upstream
may not have or be currently testing with later versions, and the
versions of dependencies in the ports tree can be updated at any time.
This is why the vast majority of correctly packaged (upstream) packages
use >= dependencies, leaving the x.y.z version specified as the 'lowest
supported version' to allow flexibility.
Setting *_requires to ">=" upstream, does not prevent upstreams from
testing specific versions themselves for their test environment, but its
recommended they QA what they distribute, which ensures issues in newer
versions of their dependencies are picked up early and often, *before*
being released to users.
If you need more help or have questions regarding porting Python
packages, jump on #freebsd-python on freenode IRC and we'll be happy to
assist.
