An error occurred (NoSuchVersion) when calling the GetObject operation: The specified version does not exist.

s3api: Check whether versioning is enabled more

Previously, attempting to GET, HEAD, or DELETE an object with a non-null
version-id would cause 500s, with logs complaining about how

version-aware operations require that the container is versioned

Now, we'll early-return with a 404 (on GET or HEAD) or 204 (on DELETE).

memcached: Plumb logger into MemcacheRing

This way proxies log memcached errors in the normal way instead of
to the root logger (which eventually gets them out on STDERR).

If no logger is provided, fall back to the root logger behavior.

swift-get-nodes: Allow users to specify either quoted or unquoted paths

    Now that we can have null bytes in Swift paths, we need a way for
    operators to be able to locate such containers and objects. Our usual
    trick of making sure the name is properly quoted for the shell won't
    suffice; running something like

swift-get-nodes /etc/swift/container.ring.gz $'AUTH_test/\0versions\0container'

has the path get cut off after "AUTH_test/" because of how argv works.

So, add a new option, --quoted, to let operators indicate that they
already quoted the path.

Drive-bys:

      * If account, container, or object are explicitly blank, treat them
        as though they were not provided. This provides better errors when
        account is explicitly blank, for example.
      * If account, container, or object are not provided or explicitly
        blank, skip printing them. This resolves abiguities about things
        like objects whose name is actually "None".
      * When displaying account, container, and object, quote them (since
        they may contain newlines or other control characters).

Don't auto-create shard containers
    
    ...unless the client requests it specifically using a new flag:
    
       X-Backend-Auto-Create: true
    
    Previously, you could get real jittery listings during a rebalance:
    
     * Partition with a shard DB get reassigned, so one primary has no DB.
     * Proxy makes a listing, gets a 404, tries another node. Likely, one of
       the other shard replicas responds. Things are fine.
     * Update comes in. Since we use the auto_create_account_prefix
       namespace for shards, container DB gets created and we write the row.
     * Proxy makes another listing. There's a one-in-three chance that we
       claim there's only one object in that whole range.
    
    Note that unsharded databases would respond to the update with a 404 and
    wait for one of the other primaries (or the old primary that's now a
    hand-off) to rsync a whole DB over, keeping us in the happy state.
    
    Now, if the account is in the shards namespace, 404 the object update if
    we have no DB. Wait for replication like in the unsharded case.
    
    Continue to be willing to create the DB when the sharder is seeding all
    the CREATED databases before it starts cleaving, though.

Switch to newer openstackdocstheme and reno versions
    
    Switch to openstackdocstheme 2.2.1 and reno 3.1.0 versions. Using
    these versions will allow especially:
    * Linking from HTML to PDF document
    * Allow parallel building of documents
    * Fix some rendering problems
    
    Update Sphinx version as well.
    
    Disable openstackdocs_auto_name to use 'project' variable as name.
    
    Set openstackdocs_pdf_link to link to PDF file. Note that
    the link to the published document only works on docs.openstack.org
    where the PDF file is placed in the top-level html directory. The
    site-preview places the PDF in a pdf directory.
    
    Change pygments_style to 'native' since old theme version always used
    'native' and the theme now respects the setting and using 'sphinx' can
    lead to some strange rendering.
    
    Remove docs requirements from lower-constraints, they are not needed
    during install or test but only for docs building.
    
    openstackdocstheme renames some variables, so follow the renames
    before the next release removes them. A couple of variables are also
    not needed anymore, remove them.

Remove <py3.5 dependencies from requirements.txt
    
    The requirements repo is support python 3.5 as oldest python version
    while swift still supports py27.
    
    thus, requirements-check will fail on a couple of lines in swift.  The
    check is only run when these files are touched.
    
    The py2.7 packagers we know about aren't depending on upstream
    requirements.txt for correctness and aside from all the production
    deployments running on py2.7 we only realistically support >=py3.7
    
    There's no good reason for our requirements.txt to be "unspported" by
    the openstack requirements check job.  Since they only support >=py3.5
    we can change our requirements.txt inline with that.  This should be
    fine for everything we could hope to get out of both our
    requirements.txt and the check!

      - object_count,
      - bytes_used,
      - state, or
      - epoch
    
    has changed, we shouldn't need to send an update back to the root
    container.
    
    This is more-or-less comparable to what the container-updater does to
    avoid unnecessary writes to the account.

    REVIEW_GUIDELINES.rst in the root of the repo. So we are also pulling
    them into the contributor documentation so they can not only be easily
    found in the checked repo but in the online documentation.

versioning: Have versioning symlinks make pre-auth requests to reserved container
    
    Previously, the lack of container ACLs on the reserved container would
    mean that attempting to grant access to the user-visible container would
    not work; the user could not access the backing object.
    
    Now, have symlinks with the allow-reserved-names sysmeta set be
    pre-authed. Note that the user still has to be authorized to read the
    symlink, and if the backing object was *itself* a symlink, that will be
    authed separately.

Breakup reclaim into batches
    
    We want to do the table scan without locking and group the locking
    deletes into small indexed operations to minimize the impact of

Bump up timeouts for DSVM and probe test jobs
    
    DSVM recently got a bunch more middlewares enabled, so it's running more
    tests than it used to.
    
    I can't think of much that's changed for probe tests, but I feel like
    I've seen it popping timeouts more often lately.
    
    Note that the new timeouts are still lower than the typical run-time of
    our longest-running jobs (currently grenade / tempest-ipv6-only).

ratelimit: Allow multiple placements
    
    We usually want to have ratelimit fairly far left in the pipeline -- the
    assumption is that something like an auth check will be fairly expensive
    and we should try to shield the auth system so it doesn't melt under the
    load of a misbehaved swift client.
    
    But with S3 requests, we can't know the account/container that a request
    is destined for until *after* auth. Fortunately, we've already got some
    code to make s3api play well with ratelimit.
    
    So, let's have our cake and eat it, too: allow operators to place
    ratelimit once, before auth, for swift requests and again, after auth,
    for s3api. They'll both use the same memcached keys (so users can't
    switch APIs to effectively double their limit), but still only have each
    S3 request counted against the limit once.

updater: Shuffle suffixes so we don't keep hitting the same failures
    
    When tuning your updater, you often want to try a new config, see how it
    changes your metrics, then adjust concurrency up or down depending on
    how your container layer is responding.
    
    If your containers haven't been doing well, though, and you've got a
    giant backlog of async pendings to work through, updater restarts to
    change concurrency previously posed a problem: the updater would walk
    the suffix directories in the same order every start-up. So, if you
    found a config that was making decent progress for a while but still had
    *some* failures, and you wanted to try tweaking settings to see if you
    could *reduce* those failures -- you'd likely start getting *all*
    failures as it went to retry the failed ones first and all at once. If
    you continued trying to tweak configs to get your failures to a
    reasonable rate, you'd almost certainly over-correct for these handful
    of overwhelmed DBs and not the overall cluster.
    
    Now, shuffle the suffixes before we walk them.

s3api: Check whether versioning is enabled more
    
    Previously, attempting to GET, HEAD, or DELETE an object with a non-null
    version-id would cause 500s, with logs complaining about how
    
        version-aware operations require that the container is versioned
    
    Now, we'll early-return with a 404 (on GET or HEAD) or 204 (on DELETE).

relinker: Improve performance by limiting I/O
    
    This commit reduce the number of I/O done by the swift-object-relinker.
    
    First, it saves a progress state of relinking and cleanup in case the
    process is interrupted during the operation. This allow to resume
    operation without rescanning all partitions.
    
    Secondly, it prevents from being scanned by relink and cleanup all
    partitions that are bigger than 2^part_power (or (2^next_part_power)/2).
    These partitions were not existing before the beginning of the part_power
    increase, so there is nothing to relink or cleanup.
    
    Thirdly, it reverse-orders the partitions to scan so that some useless
    work is avoided. If a device contains partitions 1 and 3, relinking
    partition 1 will create "new" objects in partition 3, that will need to
    be scanned when the relinker will work on partition 3. It is useless. If
    partition 3 is done first, it will only contain the objects that need to
    be relinked.
    
    Fourthly, it allows to specify a unique device to work on.
    
    To do that, some hooks were added in audit_location_generator to allow
    to execute some custom code before/after iterating a
    device/partition/suffix/hash.
