[openstack-dev] Optional Dependencies
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Hi openstack-dev, I was wondering what the correct way of handling optional dependencies is? I'm specifically talking about libraries that are only required for a specific driver for example, so they're not technically a hard requirement and the project is expected to function without them when using a driver that does not require the lib. I read through the README in openstack/requirements [1] but I didn't see anything about it.

One of the reasons we chose this one specifically is that the python ldap package requires a C library. We set up the different extra package groups in setup.cfg [extras]: [1] http://git.openstack.org/cgit/openstack/keystone/tree/setup.cfg?h=stable/liberty#n24 See pbr docs: http://docs.openstack.org/developer/pbr/#extra-requirements Here's the tox.ini line so that they're all installed for unit tests: http://git.openstack.org/cgit/openstack/keystone/tree/tox.ini?h=stable/liberty#n10 > I read through the README in openstack/requirements [1] but I didn't > see anything about it. > > > Thanks, > Douglas Mendizábal > > [1] > https://git.openstack.org/cgit/openstack/requirements/tree/README.rst > -BEGIN PGP SIGNATURE- > Comment: GPGTools - https://gpgtools.org > > iQIcBAEBCgAGBQJWCqJlAAoJEB7Z2EQgmLX72D8P/RROP9qT7DRY1jDnbK0Aj/TZ > lYujurHS70nXCj/Pw6uqsq41TttmwMdAx85yXwoLv/XBASaFYZ6eT6i0scfHBKAu > z5f0IomaJMQDGJ27By/amcE5eMiST5sEW/OCwHyZxdM8zgo3mzX1jIslmFEyPJ0z > wSah5DoZZh3J0RfQuBg8MOQgJVZo74KiNRou1uKE82cbVXJzVKjlfn+r7yO9TUtx > 9hB/77a8sDFBWI4nXluTP+Dfpy6NSW1kqwwUoDtsZACtrhTDNCDWxUUIjfyBlIKT > LdY+oVrhqWSUI/WwCop4+Aim64obaAq5yWPR6fjTlcQ3+iCYbBzzgP/9VOm/+0Nr > AGzVbIW7ah2yEDhM0yTymaay8+G1mc+jxhvwAtTxJVIJLcJXdC3XK6b00OFkO2Kt > 0dkjx/i8/riP56sb62P2a3heS3gOFqzqzwlh9SD8Omvhot3NkOr2e1QR7Cvjh1le > W5U/61vGKxmtv+iIaFXd86CRO46+4UiD1V+T0lKz083J9XuC49nkhyfuMP3ev6lc > /qD6uOnbJfyVWKRdf2PkTEe9C8YsXlxEWZ72GFC+u1jvL5K/NATUkLLWmGuv/JH+ > tPyAOPISKHh44mhJqM/K37NvJO/TloOhz0a2fW2FV8kOX1V5wVAZiQBSEWtCAI8u > 29up4yIgvi13ZkrRb94n > =fj9z > -END PGP SIGNATURE- > > __ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev > __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

Just to complete the picture, requirements listed as "extras" still need to be included in the global-requirements list so we can synchronize the versions everyone uses.
