Hey all, So, I've noticed that there are a lot of similar code in the Nova and Swift (and I presume Glance as well...) that is redundant in its purpose.
Examples of redundant code include: Configuration file and options processing ================================= In Nova, gflags is used for CLI option processing and there is the --flags-file ability to read configuration options In Swift, the getopt, optparse and ConfigParser are used throughout the codebase WSGI ===== In Nova, eventlet.wsgi is used, but wrapped with some convenience functions in /nova/wsgi.py In Swift, same thing, wrappers are in /swift/common/wsgi.py Logging ====== Both Nova and Swift use the standard logging module with some utility wrappers linked with the way configuration options are processed. Common utility functions ==================== Nova contains a file /nova/utils.py containing common utility functions. Swift contains a file /swift/common/utils.py also containing utility functions, many serving similar purposes of those in Nova and vice versa My proposal is to create another project on Launchpad called openstack-common that will contain a Python library that standardizes and consolidates all the above-mentioned overlap and makes an easy-to-use, well-documented library of common utilities and modules for the OpenStack family of projects to use. We could definitely be more efficient in re-using code from Nova and Swfit that are redundant, and it would be good to have a common way of, for instance, accessing program configuration options and such. Thoughts? -jay _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
