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