I want to give an update on http://specs.openstack.org/openstack/openstack-specs/specs/requirements-management.html - we've just passed a critical milestone there, and this affects how everyone updates requirements.
As of a few minutes ago devstack-gate landed the change to set USE_CONSTRAINTS=True. What this means is that the file http://git.openstack.org/cgit/openstack/requirements/tree/upper-constraints.txt is now used to determine the version of every dependency that is present in it. It is created by the script 'generate-constraints' in the same repository, and there's an infra job that will propose changes to that file based on what is in PyPI. Its currently pending a couple of tweaks to get it fully operational but we should resume operations in the near future. This constraints file can be used for local development too - just set USE_CONSTRAINTS=True in your stack config file. Now, the things you have to remember as developers: * If you are adding a new requirement you should also add it to upper-constraints.txt with an exact pin. * If you are raising a minimum version of a requirement, you need to also raise it in upper-constraints.txt. * New releases of *any* library will not be used by devstack-gate jobs until upper-constraints.txt has been edited to enable them. This makes it much much harder to break the world, for all of us that release things - whether it be upstream components like testtools, oslo libraries or the python-$FOOclient libraries. -Rob -- Robert Collins <[email protected]> Distinguished Technologist HP Converged Cloud __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
