Joshua Hawkinson reopened LIBCLOUD-986:
---------------------------------------
Ah, I found a bug in my code upon further testing – reopening and putting
another pull request in (Sorry about that) :(
> List / Iterate container with prefix for Azure Blob service (This support
> exists in the other drivers already)
> --------------------------------------------------------------------------------------------------------------

> Key: LIBCLOUD-986
> URL: https://issues.apache.org/jira/browse/LIBCLOUD-986
> Project: Libcloud
> Issue Type: Improvement
> Components: Storage
> Reporter: Joshua Hawkinson
> Priority: Major
>
> While testing out the libcloud storage abstraction I've come across a curious
> omission in driver support. It seems that for many drivers there is
> additional support for the {{list_container_objects()}} and
> {{iterate_container_objects()}} to support a prefix (or {{ex_prefix)}}.
> This functionality is not present in the Azure driver for some reason. I've
> gone and checked the list_blobs API and it also supports this functionality
> as seen here:
> [https://docs.microsoft.com/en-us/rest/api/storageservices/list-blobs]
>
> I've attempted a quick and dirty patch that seems to work as well.

> :rtype: ``list`` of :class:`Object`
> """
> return list(self.iterate_container_objects(container,
> ex_prefix=ex_prefix))

> {code}

> I've just worked around this at a higher level for now. There isn't any
> urgency on my end, but it would be nice if the abstraction was more
> consistent so I could remove the workaround code.
