glance-scrubber not scrubbing with swift backend

[Paul Bourke]

It seems the fix for bug #1052537 was incomplete, as I have found glance-scrubber is still not completing it's work when run against a swift backend.

With more investigation it seems the proper way to execute a starmap/imap is to consume it within a loop. This can be replicated by taking the simple web crawler example from http://eventlet.net/doc/ and removing the for loop from around the imap call.

    Fix scrubber not scrubbing with swift backend

    It seems the fix for bug #1052537 was incomplete, as I have found
    glance-scrubber is still not completing it's work when run against a
    swift backend.

    With more investigation it seems the proper way to execute a
    starmap/imap is to consume it within a loop. This can be replicated by
    taking the simple web crawler example from http://eventlet.net/doc/ and
    removing the for loop from around the imap call.

    Also:
    * Add new test to check this failure against Swift (respects the
      GLANCE_TEST_SWIFT_CONF environment variable).

    Fixes bug 1056127
