Re: [scl.org] Python "latest" SCLo



I will be able to provide testing, and I'll follow along.

Your note about how fast it will move really points out that we need to learn how to do it ourselves, because we will want to move both fast and slow, at times.

So I finally started working on the technical aspects of this, and as near as I can figure out, what I'll need to do is:

1. Create a new sclo-python metapackage, using https://github.com/sclorg-distgit/rh-python35/tree/master as a starting point 2. For now, just create a `sig-sclo7-sclo-python` branch (we can look at an sclo6 branch once 7 is working) 3. Edit https://github.com/ncoghlan/sclo-python/tree/sig-sclo7-sclo-python
for the rh-python35 -> sclo-python name change 4. Start doing some test builds in COPR as per https://www.softwarecollections.org/en/docs/

In parallel with that:

4. Submit a buildsys request for an sclo-python tag that's similar to the existing rh-python35 one (akin to
https://bugs.centos.org/view.php?id=9661 ) 5. Figure out what, if anything, needs to be done in terms of adding relevant branches to the other Python repos on https://github.com/sclorg-distgit 6. Actually start building real SCLs in the CentOS build system for publication to softwarecollections.org

Cheers,
Nick.

P.S. Additional next step: provide feedback to the Fedora Modularity group on which aspects of this strike me as being the most annoyingly tedious, and what could potentially be done to make distro-submodule-based SCL definitions and updates less time consuming than the current process based directly on RPMs and dist-git :)
