    Fix some request-smuggling vectors on py3
    
    A Python 3 bug causes us to abort header parsing in some cases. We
    mostly worked around that in the related change, but that was *after*
    eventlet used the parsed headers to determine things like message
    framing. As a result, a client sending a malformed request (for example,
    sending both Content-Length *and* Transfer-Encoding: chunked headers)
    might have that request parsed properly and authorized by a proxy-server
    running Python 2, but the proxy-to-backend request could get misparsed
    if the backend is running Python 3. As a result, the single client
    request could be interpretted as multiple requests by an object server,
    only the first of which was properly authorized at the proxy.
    
    Now, after we find and parse additional headers that weren't parsed by
    Python, fix up eventlet's wsgi.input to reflect the message framing we
    expect given the complete set of headers. As an added precaution, if the
    client included Transfer-Encoding: chunked *and* a Content-Length,
    ensure that the Content-Length is not forwarded to the backend.

    py3: Allow percentages in configs
    
    Previously, configs like
    
        fallocate_reserve = 1%
    
    would cause a py3 backend server to fail to start, complaining like
    
        configparser.InterpolationSyntaxError: Error in file
        /etc/swift/object-server/1.conf.d: '%' must be followed
        by '%' or '(', found: '%'
    
    This could also come up in proxy-server configs, with things like
    percent signs in tempauth password.
    
    In general, we haven't really thought much about interpolation in
    configs. Python's default ConfigParser has always supported it, though,
    so we got it "for free". On py2, we didn't really have to think about
    it, since values like "1%" would pass through just fine. (It would blow
    up a SafeConfigParser, but a normal ConfigParser only does replacements
    when there's something like a "%(opt)s" in the value.)
    
    On py3, SafeConfigParser became ConfigParser, and the old interpolation
    mode (AFAICT) doesn't exist.
    
    Unfortunatley, since we "supported" interpolation, we have to assume
    there are deployments in the wild that use it, and try not to break
    them.  So, do what we can to mimic the py2 behavior.

    sharder: Keep cleaving on empty shard ranges
    
    When a container is being cleaved there is a possiblity that we're
    dealing with an empty or near empty container created on a handoff node.
    These containers may have a valid list of shard ranges, so would need
    to cleave to the new shards.
    Currently, when using a `cleave_batch_size` that is smaller then the
    number of shard ranges on the cleaving container, these containers will
    have to take a few shard passes to shard, even though there maybe
    nothing in them.
    
    This is worse if a really large container is sharding, and due to being
    slow, error limitted a node causing a new container on a handoff
    location. This empty container would have a large number of shard ranges
    and could take a _very_ long time to shard away, slowing the process
    down.
    
    This patch eliminates the issue by detecting when no objects are
    returned for a shard range. The `_cleave_shard_range` method now
    returns 3 possible results:
    
      - CLEAVE_SUCCESS
      - CLEAVE_FAILED
      - CLEAVE_EMPTY
    
    They all are pretty self explanitory. When `CLEAVE_EMPTY` is returned
    the code will:
    
      - Log
      - Not replicate the empty temp shard container sitting in a
        handoff location
      - Not count the shard range in the `cleave_batch_size` count
      - Update the cleaving context so sharding can move forward
    
    If there already is a shard range DB existing on a handoff node to use
    then the sharder wont skip it, even if there are no objects, it'll
    replicate it and treat it as normal, including using a `cleave_batch_size`
    slot.

    Add func test for changing versionining modes
    
    Users are able to change versioning in a container
    from X-Versions-Location to X-History-Location, which affects
    how DELETEs are handled. We have some unit tests that check this
    behavior, but no functional tests.
    
    This patch adds a functional test that helps us understand and
    document how changing modes affects the handling of DELETE
    requests.

    Sharding: Use the metadata timestamp as last_modified
    
    This is a follow up patch from the cleaning up cleave context's patch
    (patch 681970). Instead of tracking a last_modified timestamp, and storing
    it in the context metadata, use the timestamp we use when storing any
    metadata.
    
    Reducing duplication is nice, but there's a more significant reason to
    do this: affected container DBs can start getting cleaned up as soon as
    they're running the new code rather than needing to wait for an
    additional reclaim_age.

      though Content-Length doesn't determine request body size.

    Sharding: Clean up old CleaveConext's during audit
    
    There is a sharding edge case where more CleaveContext are generated and
    stored in the sharding container DB. If this number get's high enough,
    like in the linked bug. If enough CleaveContects build up in the DB then
    this can lead to the 503's when attempting to list the container due to
    all the `X-Container-Sysmeta-Shard-Context-*` headers.
    
    This patch resolves this by tracking the a CleaveContext's last
    modified. And during the sharding audit, any context's that hasn't been
    touched after reclaim_age are deleted.
    
    This plus the skip empty ranges patches should improve these handoff
    shards.

    [train][goal] Run 'tempest-ipv6-only' job in gate
    
    As part of Train community goal 'Support IPv6-Only Deployments and Testing'[1],
    Tempest has defined the new job 'tempest-ipv6-only'(adding
    in Depends-On patch) which will deploy services on IPv6 and run smoke
    tests and IPv6 related tests present in Tempest.
    
    This job will be part of Nova, Neutron, Cinder, Keystone, Glance, Swift
    gate.
    
    Verification structure will be:
    - 'devstack-IPv6' deploy the service on IPv6
    - 'devstack-tempest-ipv6' run will verify the IPv6-only setting and listen address
    - 'tempest-ipv6-only' will run the smoke + IPv6 related test case.
    
    This commit adds the new job 'tempest-ipv6-only' run on gate.

    bufferedhttp: ensure query params are properly quoted
    
    Recent versions of py27 [1] have begun raising InvalidURL if you try to
    include non-ASCII characters in the request path. This was observed
    recently in the periodic checks of stable/ocata and stable/pike. In
    particular, we would spin up some in-process servers in
    test.unit.proxy.test_server.TestSocketObjectVersions and do a container
    listing with a prefix param that included raw (unquoted) UTF-8. This
    query string would pass unmolested through the proxy, tripping the
    InvalidURL error when bufferedhttp called putrequest.
    
    More recent versions of Swift would not exhibit this particular failure,
    as the listing_formats middleware would force a decoding/re-encoding of
    the query string for account and container requests. However, object
    requests with errant query strings would likely be able to trip the same
    error.
    
    Swift on py3 should not exhibit this behavior, as we so
    thoroughly re-write the request line to avoid hitting
    https://bugs.python.org/issue33973.
    
    Now, always parse and re-encode the query string in bufferedhttp. This
    prevents any errors on object requests and cleans up any callers that
    might use bufferedhttp directly.

    Allow arbitrary UTF-8 strings as delimiters in listings
    
    AWS seems to support this, so let's allow s3api to do it, too.
    
    Previously, S3 clients trying to use multi-character delimiters would
    get 500s back, because s3api didn't know how to handle the 412s that the
    container server would send.
    
    As long as we're adding support for container listings, may as well do
    it for accounts, too.

    tests/py3: Improve header casing
    
    Previously, our unit tests with socket servers would let eventlet
    capitalize headers on the way out, which
    
    - isn't something we want to have eventlet do, because it
    - breaks unicode-in-header-names on py3, so it
    - is already disabled in swift.common.wsgi.run_server() for real servers.
    
    Include a test to make sure we don't forget about it in the future.

    py3: Finish porting func tests
    
    We were (indirectly) importing swiftclient (and therefore requests and
    urllib3) before doing our eventlet monkey-patching. This would lead
    boto3 (which digs an SSLContext out of urllib3) to trip RecursionErrors
    on py3 similar to
    
       >>> from ssl import SSLContext, PROTOCOL_SSLv23
       >>> import eventlet
       >>> eventlet.monkey_patch(socket=True)
       >>> SSLContext(PROTOCOL_SSLv23).options |= 0
       Traceback (most recent call last):
         File "<stdin>", line 1, in <module>
         File "/usr/lib/python3.6/ssl.py", line 465, in options
           super(SSLContext, SSLContext).options.__set__(self, value)

    py3: fix up listings on sharded containers
    
    We were playing a little fast & loose with types before; as a result,
    marker/end_marker weren't quite working right. In particular, we were
    checking whether a WSGI string was contained in a shard range, while
    ShardRange assumes all comparisons are against native strings.
    
    Now, get everything to native strings before making comparisons, and
    get them back to wsgi when we shove them in the params dict.

    s3api: paginate listings when aborting MPUs
    
    Even when your cluster's configured funny, like your
    container_listing_limit is too low, or your max_manifest_segments and
    max_upload_part_num are too high, an abort should (attempt to) clean up
    *all* segments.

    ring: Track more properties of the ring
    
    Plumb the version from the ringbuilder through to the metadata at the
    start of the ring. Recover this (if available) when running
    
        swift-ring-builder <ring> write_builder
    
    When we load the ring, track the count and MD5 of the bytes off disk, as
    well as the number of uncompressed bytes.
    
    Expose all this new information as properties on the Ring, along with
    
      - device_count (number of non-None entries in self._devs),
      - weighted_device_count (number of devices that have weight), and
      - assigned_device_count (number of devices that actually have
        partition assignments).

    Fix invalid assert states
    
    This is to fix invalid assert states like:
        self.assertTrue('sync_point2: 5', lines.pop().strip())
        self.assertTrue('sync_point1: 5', lines.pop().strip())
        self.assertTrue('bytes: 1100', lines.pop().strip())
        self.assertTrue('deletes: 2', lines.pop().strip())
        self.assertTrue('puts: 3', lines.pop().strip())
        self.assertTrue('1', jobs_to_delete[0]['partition'])
    in which assertEqual should be used.

    We don't have to keep the retrieved token anymore
    
    Since the change in s3_token_middleware to retrieve the auth info
    from keystone directly, now, we don't need to have any tokens provided
    by keystone in the request header as X-Auth-Token.
    
    Note that this makes the pipeline ordering change documented in the
    related changes mandatory, even when working with a v2 Keystone server.

    Fix a potential bug
    
    In the class method from_hash_dir(), the arguments to input when creating an instance of the BaseDiskFile class are incorrect.
    The __init__() method of BaseDiskFile class receive the arguments in order of mgr, device_path, partition and etc.
    However, in from_hash_dir() method, the order of arguments are mgr, device_path, None and partition
    The class method from_hash_dir() is used by the Object Auditor.
    If the partition argument is used in the new DiskFile implementations, exception may occur.
    It will be cause object auditing to failed and the object will be quarantine by the Object Auditor.
