Bug Description

Dynamic Large Objects can be uploaded with the swift CLI, but there is no obvious python API exposed for this in the client module.

I would have expected to find a parameter to specify the segment size in the put_object method.

Some discussion happened on the OS mailing list: http://comments.gmane.org/gmane.comp.cloud.openstack.general/10924

The client module is designed as a low-level API; in particular, put_object is only designed to PUT a single object, while DLOs necessarily involve several objects. To create a DLO with the client module, you'll need to upload the segments individually, then upload a manifest (which is just a zero-byte object with a X-Object-Manifest header).

Of course, that's a tedious process. You can also use the SwiftService object in the service module, which provides a higher-level API and takes the expected segment_size option in its upload method.
