Fixes bug #1194807 Firstly, we update the oslo.config dep to 1.2.0a3 because of the issue with namespace packages (bug #1194742). But the main issue here is that when we previously depended on 1.2.0a3 we found that if you did: $> pip install -r nova/requirements.txt then you end up with the oslo.config 1.1.1 code installed. This is because oslo.config>=1.1.0 gets pulled in as a transitive dep and pip gets confused. See I977700d73342e81ee962019b76238d2cb2b1fff4 You can reproduce with e.g. $> pip install \ http://.../oslo.config-1.2.0a3.tar.gz#egg=oslo.config-1.2.0a3 \ python-keystoneclient $> pip freeze | grep oslo.config oslo.config-1.2.0a3 $> python -c 'from oslo.config.cfg import DeprecatedOpt' Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: cannot import name DeprecatedOpt This is because of a bug with pip where it sees oslo.config-1.2.0a3 and oslo.config as two unrelated things. It should strip the version part of the egg= fragment before using it as a package name, but it doesn't. However, we can simply use the -f/--find-links pip option in our requirements.txt to add the tarball URL to the list of URLs considered and also add the oslo.config>=1.2.0a3 dependency: $> pip install \ -f http://.../oslo.config-1.2.0a3.tar.gz#egg=oslo.config-1.2.0a3 \ 'oslo.config>=1.2.0a3' \ python-keystoneclient $> pip freeze | grep oslo.config oslo.config-1.2.0a3 $> python -c 'from oslo.config.cfg import DeprecatedOpt' This is actually exactly the semantics we want and we go to great lengths in pbr to get these semantics while using a single tarball URL. The only downside to this --find-links strategy is that we gain an extra line in our requirements.txt ... but it does work around the pip bug. Change-Id: I6f3eb5fd2c75615d9a1cae172aed859b36b27d4c
OpenStack Nova README ===================== OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of virtualization technologies, including KVM, Xen, LXC, VMware, and more. In addition to its native API, it includes compatibility with the commonly encountered Amazon EC2 and S3 APIs. OpenStack Nova is distributed under the terms of the Apache License, Version 2.0. The full terms and conditions of this license are detailed in the LICENSE file. Nova primarily consists of a set of Python daemons, though it requires and integrates with a number of native system components for databases, messaging and virtualization capabilities. To keep updated with new developments in the OpenStack project follow `@openstack <http://twitter.com/openstack>`_ on Twitter. To learn how to deploy OpenStack Nova, consult the documentation available online at: http://docs.openstack.org For information about the different compute (hypervisor) drivers supported by Nova, read this page on the wiki: https://wiki.openstack.org/wiki/HypervisorSupportMatrix In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at: http://bugs.launchpad.net/nova Developers wishing to work on the OpenStack Nova project should always base their work on the latest Nova code, available from the master GIT repository at: http://github.com/openstack/nova Developers should also join the discussion on the mailing list, at: https://lists.launchpad.net/openstack/ Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests. Further developer focused documentation is available at: http://nova.openstack.org/ For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst file. -- End of broadcast
