Fix potential missing key error in container_info

    If upgrading from a non-storage policy enabled version of
    swift to a storage policy enabled version its possible that
    memcached will have an info structure that does not contain
    the 'storage_policy" key resulting in an unhandled exception
    during the lookup. The fix is to simply make sure we never
    return the dict without a storage_policy key defined; if it
    doesn't exist its safe to make it '0' as this means you're
    in the update scenario and there's xno other possibility.

Fix exception raising in FakeConn

    Timeout isn't an Exception, so Timeouts in tests weren't getting
    raised. Instead, you'd sometimes have an HTTPResponse's .status be a
    Timeout object, not an integer, which greatly confuses code that
    expects an integer.

    Also reorder the test that exposed the failure in the gate so it blows
    up most times instead of sometimes do demonstrate the failure with out
    this fix to FakeConn.

Fix pop_queue for move object twice
    
    With the two vector timestamp change some resolution was lost in the queue
    entries that could lead to the reconciler being unable to successfully remove
    a processed item from the queue in pop_queue.  To ensure the queue entries
    with a significant offset can be successfully removed while still handling
    the re-enqueued object case issue the DELETE with the timestamp slightly later
    than the maximum of the queue entries last modified time (q_record) and
    misplaced objects timestamp (q_ts).

Small cleanup to ring serialization
    
    Instead of catching TypeError and retrying without mtime, let's just
    check and see if mtime is an allowed arg and decide based on
    that. This way, if anything else raises TypeError we'll know about it.

Container Auditor should log a warning if the devices path contains a non-directory.
    
    If the devices path configured in container-server.conf contains a file
    then an uncaught exception is seen in the logs. For example if file foo exists as such
    /srv/1/node/foo then when the container-auditor runs, the exception that foo/containers is
    not a directory is seen in the logs
    
    This patch was essentially clayg and can be found in the bug
    
    I tested it and wanted to get a feel of the openstack workflow so going through the
    commit process
    
    I have added a unit test as well as cleaned up and improved the unit test coverage
    for this module.
    - unit test for above fix is added
    - unit test to verify exceptions that are raised in the module
    - unit test to verify the logger's behavior
    - unit test to verify mount_check behavior

Fix KeyError on Storage Policy Container Sync
    
    In the proxy, container_info can return a 'storage_policy' of None.  When
    you set a header value on a swob.Request to None that effectively just
    delete's the key.  One path through the proxy during container sync was
    counting on the the 'X-Backend-Storage-Policy-Index' being set which isn't
    the case if the cached container_info if for a pre-policies container.
    
    Also clean up some test cruft, tighten up the interface on FakeConn, and add
    some object controller tests to exercise more interesting failure and handoff
    code paths.

Add SAIO fix for Ubuntu 12.04
    
    The version of setup tools in Ubuntu 12.04 is too old and is causing
    the SAIO instructions to fail when installing python-swiftclient.
    
    The work around is to install python-swiftclient's dependencies
    before running running:
    
      python setup.py develop
    
    This change adds a note to users of Ubuntu 12.04 to replace step 2
    of "Getting the code" with:
    
      cd $HOME/python-swiftclient; sudo pip install -r requirements.txt; \
                                   python setup.py develop; cd -

Parallel object auditor
    
    We are soon going to put servers with a high ratio of disk to CPU
    into production as object servers.  One of our concerns with this
    configuration is that the object auditor would take too long to
    complete its audit cycle.  Therefore we decided to parallelise
    the auditor.
    
    The auditor already uses fork(), so we decided to use the parallel
    model from the replicator.  Concurrency is set by the concurrency
    parameter in the auditor stanza, which sets the number of parallel
    checksum auditors.  The actual number of parallel auditing processes
    is concurrency + 1 if zero_byte_fps is non-zero.
    
    Only one ZBF process is forked, and a new ZBF process is forked as
    soon as the current ZBF process finishes.  Thus the last process
    running will always be a ZBF process.
    
    Both forever and once modes are parallelised.
    
    Each checksum auditor process submits a nested dictionary with keys
    {'object_auditor_stats_ALL': {'diskn': {..}}} to dump_recon_cache
    so that the object_auditor_stats_ALL dict in recon cache consists
    of individual sub-dicts for each of the object disks on the server.
    The recon cache is no different to before when the checksum auditor
    is run in serial mode.  When swift-recon is run, it sums the stats
    for the individual disks.

Fix swift-recon --auditor bug
    
    I introduced a bug in swift-recon --auditor, which Christian
    Schwede uncovered.  Christian proposed a fix which replaces the
    generator nested_get_value with a recursive function which
    returns just one instance of a key.  Christian's fix will break
    the parallel object auditor patch which uses the generator to
    return all instances of a particular key in a nested dictionary
    and then sums those values.
    
    This alternative fix sums over all values returned by
    nested_get_value, as is done in the parallel auditor patch.

Don't count 412 or 416 as errors in stats
    
    The backend HTTP servers emit StatsD metrics of the form
    <server>.<method>.timing and <server>.<method>.errors.timing
    (e.g. object-server.GET.timing). Whether something counts as an error
    or not is based on the response's HTTP status code.
    
    Prior to this commit, "success" was 2xx, 3xx, or 404, while everything
    else was considered "error". This adds 412 and 416 to the "success"
    set. Like 404, these status codes indicate that we got the request and
    processed it without error, but the response was "no". They shouldn't
    be in the same category as statuses like 507 that indicate something
    stopped the request from being processed.

Fix issues with test_wsgi.py and Storage Policies
    
    Discovered some tests that were coupling the code under test with the
    storage policies configured in /etc/swift/swift.conf.  There was some
    tests that created fake rings in their tempdirs, but didn't reset or
    patch the POLICIES global.  So if your local config needed more rings
    that the fake's were setting up (just 2) the tests would puke when they
    loaded up an app that looked for rings.  I think this probably started
    happening when we added eager object ring loading back into the proxy.
    
     * two TestCases in test_wsgi were missing @patch_policies
     * fixed issue with patch_policies that could cause state to bleed
       between tests
     * patch_policies' legacy and default collections get a FakeRing by
       default
    
     * drive-by cleanup for test_loadapp_proxy() ring serialized path
       handling
     * drive-by cleanup for test_internal_client that was doing basically
       the same thing as test_wsgi

Fix SLO test with old simplejson
    
    Our requirements.txt contains "simplejson>=2.0.9". With that version,
    attempting to decode invalid JSON raises ValueError, not
    simplejson.JSONDecodeError. In fact, there is no such thing as
    JSONDecodeError; it isn't introduced until a later version. Also,
    stdlib's json module doesn't have a JSONDecodeError either. However,
    JSONDecodeError inherits from ValueError, so we can just catch that
    instead.
    
    Also added a better failure message when invalid JSON is detected;
    we'll now fail immediately instead of later in some assertEqual().
