Project overview and update

TONY BREEDS PRINCIPAL SOFTWARE ENGINEER - REDHAT

2019-05-01

What does Requirements do?

• Manages OpenStack wide python

requirements

• Coordinating and converging the

libraries used by OpenStack projects, while ensuring that all libraries are compatible both technically and from a licensing standpoint.

Project background

• Separate team created at the Austin

(2016) summit

• 49 of contributors for the stein release
• 4 active core reviewers
• Used by pretty much all of OpenStack :)

New features & enhancements for Stein

➔STATIC CONSTRAINTS URLS

• Publish constraints fjles to a URL that isn’t based on git state

• Mostly complete
• urls exist and were used to branch stein
• See later :)

Continuing work for Train

➔PER-PROJECT REQUIREMENTS / LOWER-CONSTRAINTS

• Allows each OpenStack project to defjne and maintain lists of dependencies while maintaining co-

installability

• Also allows teams to specify and (unit) test lower bounds.

Possible features & enhancements for Train

➔REMOVAL OF LEGACY ‘PROJECTS.TXT’

• This used to be the defjnitive list which OpenStack projects were co-installable.
• It’s no longer needed or maintained but there are several places using it.

➔STATIC CONSTRAINTS URLS

• Fixing older stable branches is easy
• master is harder

➔CORRECT PYTHON3* SUPPORT

• Supporting multiple minor versions of python3 in constraints needs work
• For example python 3.7 is only partially using constraints

Possible features & enhancements for Train

➔CONSUMPTION OF OPENSTACK SERVICES

• What’s the correct way to consume service projects?

Possible features & enhancements for Train+

➔INTEGRATED LOWER-CONSTRAINTS?

• Enable more than simple unit tests on lower-constraints

➔EDUCATION!

• We’ve had a lot of change in the last few cycles make sure documentation is right and community

knows about the new tools and process ➔STABLE POLICY UPDATES?

• Much of the policy is in place to help distributions and vendors
• Make sure it’s the right policy
