Tim Burke a4fb70ece1 Compare each chunk of large objects when uploading
Previously, we compared the ETag from Swift against the MD5 of the
entire large object. However, the ETag for large objects is generally
the MD5 of the concatenation of the ETags for each segment, unless the
object is a DLO whose segments span more than one page of a container
listing. Rather than worry about ETags, just compare each chunk of the
segmented file. This allows the use of --skip-identical when uploading
SLOs and DLOs.

Additionally, there are several test-related improvements:
 * The default arguments for OutputManager are now evaluated on
   construction, rather than on definition, so that
   TestOutputManager.test_instantiation will succeed when using nosetest
   as a test runner. (See also: bug 1251507)
 * An account_username option is now available in the functional tests
   config file for auth systems that do not follow the account:username
   format.
 * CaptureOutput no longer writes to the captured stream, and
   MockHttpTest now captures output. These were polluting test output
   unnecessarily. (See also: bug 1201376)

Python bindings to the OpenStack Object Storage API

This is a python client for the Swift API. There's a Python API (the swiftclient module), and a command-line script (swift).

You can find the documentation online.

Development takes place via the usual OpenStack processes as outlined in the OpenStack wiki. The master repository is on GitHub.

This code is based on original the client previously included with OpenStack's swift The python-swiftclient is licensed under the Apache License like the rest of OpenStack.
