	OpenStack Object Storage (swift)	Fix Released	Wishlist	Kamil Rykowski	OpenStack Object Storage (swift) 2.4.0

Bug Description

swift-object-info should split out user and system metadata - and for system metadata at least it should output keys line by line instead of spitting it out in as a dict repr so it's easier to parse with grep

Fix best response to return correct status

    Current best response could return "503 Internal Server Error".
    However, "503" means "Service Unavailable". (The status int of
    Internal Server Error is 500)

This patch fixes the response status as "503 Service Unavailable"

Don't apply the wrong Etag validation to rebuilt fragments

    Because of the object-server's interaction with ssync sender's
    X-Backend-Replication-Headers when a object (or fragment archive) is
    pushed unmodified to another node it's ETag value is duped into the
    recieving ends metadata as Etag. This interacts poorly with the
    reconstructor's RebuildingECDiskFileStream which can not know ahead of
    time the ETag of the fragment archive being rebuilt.

Don't send the Etag from the local source fragment archive being used as
the basis for the rebuilt fragent archive's metadata along to ssync.

Check if REST API version is valid
    
    Swift doesn't check if the used API version is valid. Currently there
    is only one valid REST API version, but that might change in the
    future.
    
    This patch enforces "v1" or "v1.0" as the version string when accessing
    account, containers and objects.
    
    The list of accepted version strings can be manually overridden using a
    comma-separated list in swift.conf to make this backward-compatible.
    The constraint loader has been modified slightly to accept strings as
    well as integers.
    
    Any request to an account, container, and object which does not
    provide the correct version string will get a 400 BadRequest response.
    
    The allowed api versions are by default excluded from /info.

Add lowest option to swift-recon disk usage output
    
    Currently there is a "--top" option when running swift-recon for
    disk usage stats. This option lists the x disks with the highest
    disk usage in descending order.
    
    This feature adds a "--lowest" option which does the opposite and
    lists the y disks with lowest disk usage in ascending order.
    
    Have also updated the docs section with --top and --lowest options

Refactor the getting roles logic in _keystone_identity
    
    The list_from_csv in swift.common.utils is used from the composite
    auth token support and this method has been used in
    _integral_keystone_identity. There is same logic in
    _keystone_identity so the logic would be replaced with list_from_csv.

Check if device name is valid when adding to the ring
    
    Currently device names can be empty or start and/or end with spaces.
    This can create unexpected results, for example these three commands
    are all valid:
    
    swift-ring-builder account.builder add "r1z1-127.0.0.1:6000/" 1
    swift-ring-builder account.builder add "r1z1-127.0.0.1:6000/sda " 1
    swift-ring-builder account.builder add "r1z1-127.0.0.1:6000/ meta" 1
    
    This patch validates device names and prevents empty names or names
    starting and/or ending with spaces.
    
    Also fixed the test "test_warn_at_risk" - the test passed if the
    exception was not raised.

Erasure Code Reconstructor
    
    This patch adds the erasure code reconstructor. It follows the
    design of the replicator but:
      - There is no notion of update() or update_deleted().
      - There is a single job processor
      - Jobs are processed partition by partition.
      - At the end of processing a rebalanced or handoff partition, the
        reconstructor will remove successfully reverted objects if any.
    
    And various ssync changes such as the addition of reconstruct_fa()
    function called from ssync_sender which performs the actual
    reconstruction while sending the object to the receiver

Fix account reaper for > 3 replicas
    
    There's a pre-existing IndexError in the pop from the container node
    list in reaper's reap_object method for object rings with a replica
    count greater than the container replica count.  Which is more likely
    on EC storage policies.
    
    When making the backend direct delete requests to the nodes once the
    container node's list is exhausted the generic exception handler logs
    the error and breaks out of any other backend object requests - but
    the reaper marches forward and eventually the tombstones are
    replicated.
    
    This change just cycles the container headers across all the nodes -
    which seems reasonable enough - but could certainly garner
    bikeshedding.

Update container sync to use internal client
    
    This patch changes container sync to use Internal Client instead
    of Direct Client.
    
    In the current design, container sync uses direct_get_object to
    get the newest source object(which talks to storage node directly).
    This works fine for replication storage policies however in
    erasure coding policies, direct_get_object would only return part
    of the object(it's encoded as several pieces). Using Internal
    Client can get the original object in EC case.
    
    Note that for the container sync put/delete part, it's working in
    EC since it's using Simple Client.

Foundational support for PUT and GET of erasure-coded objects
    
    This commit makes it possible to PUT an object into Swift and have it
    stored using erasure coding instead of replication, and also to GET
    the object back from Swift at a later time.
    
    This works by splitting the incoming object into a number of segments,
    erasure-coding each segment in turn to get fragments, then
    concatenating the fragments into fragment archives. Segments are 1 MiB
    in size, except the last, which is between 1 B and 1 MiB.

             ...                     ...
    
    Then, object server A gets the concatenation of fragment A-1, A-2,
    ..., A-N, so its .data file looks like this (called a "fragment archive"):
    
    +=====================================================================+
    |     fragment A-1     |     fragment A-2     |  ...  |  fragment A-N |
    +=====================================================================+
    
    Since this means that the object server never sees the object data as
    the client sent it, we have to do a few things to ensure data
    integrity.
    
    First, the proxy has to check the Etag if the client provided it; the
    object server can't do it since the object server doesn't see the raw
    data.
    
    Second, if the client does not provide an Etag, the proxy computes it
    and uses the MIME-PUT mechanism to provide it to the object servers
    after the object body. Otherwise, the object would not have an Etag at
    all.
    
    Third, the proxy computes the MD5 of each fragment archive and sends
    it to the object server using the MIME-PUT mechanism. With replicated
    objects, the proxy checks that the Etags from all the object servers
    match, and if they don't, returns a 500 to the client. This mitigates
    the risk of data corruption in one of the proxy --> object connections,
    and signals to the client when it happens. With EC objects, we can't
    use that same mechanism, so we must send the checksum with each
    fragment archive to get comparable protection.
    
    On the GET path, the inverse happens: the proxy connects to a bunch of
    object servers (M of them, for an M+K scheme), reads one fragment at a
    time from each fragment archive, decodes those fragments into a
    segment, and serves the segment to the client.
    
    When an object server dies partway through a GET response, any
    partially-fetched fragment is discarded, the resumption point is wound
    back to the nearest fragment boundary, and the GET is retried with the
    next object server.
    
    GET requests for a single byterange work; GET requests for multiple
    byteranges do not.
    
    There are a number of things _not_ included in this commit. Some of
    them are listed here:
    
     * multi-range GET
    
     * deferred cleanup of old .data files
    
     * durability (daemon to reconstruct missing archives)

commit b1eda4aef8a228961d5aafe7e4fbd4e812d233ad

Allow sending object metadata after data
    
    This lets the proxy server send object metadata to the object server
    after the object data. This is necessary for EC, as it allows us to
    compute the etag of the object in the proxy server and still store it
    with the object.
    
    The wire format is a multipart MIME document. For sanity during a
    rolling upgrade, the multipart MIME document is only sent to the
    object server if it indicates, via 100 Continue header, that it knows
    how to consume it.
    
    Example 1 (new proxy, new obj server):
    
       proxy: PUT /p/a/c/o
              X-Backend-Obj-Metadata-Footer: yes
    
         obj: 100 Continue
            X-Obj-Metadata-Footer: yes
    
       proxy: --MIMEmimeMIMEmime...
    
    Example2: (new proxy, old obj server)
    
       proxy: PUT /p/a/c/o
              X-Backend-Obj-Metadata-Footer: yes
    
         obj: 100 Continue
    
       proxy: <obj body>

Per-policy DiskFile classes
    
    Adds specific disk file classes for EC policy types.
    
    The new ECDiskFile and ECDiskFileWriter classes are used by the
    ECDiskFileManager.
    
    ECDiskFileManager is registered with the DiskFileRouter for use with
    EC_POLICY type policies.
    
    Refactors diskfile tests into BaseDiskFileMixin and BaseDiskFileManagerMixin
    classes which are then extended in subclasses for the legacy
    replication-type DiskFile* and ECDiskFile* classes.
    
    Refactor to prefer use of a policy instance reference over a policy_index
    int to refer to a policy.
    
    Add additional verification to DiskFileManager.get_dev_path to validate the
    device root with common.constraints.check_dir, even when mount_check is
    disabled for use in on a virtual swift-all-in-one.

Add support for policy types, 'erasure_coding' policy
    
    This patch extends the StoragePolicy class for non-replication storage
    policies, the first one being "erasure coding".
    
    Changes:
    
     - Add 'policy_type' support to BaseStoragePolicy class
     - Disallow direct instantiation of BaseStoragePolicy class
    
     - Subclass BaseStoragePolicy
    
       - "StoragePolicy":
         . Replication policy, default
         . policy_type = 'replication'
    
       - "ECStoragePolicy":
         . Erasure Coding policy
         . policy_type = 'erasure_coding'
         . Private member variables
           ec_type (EC backend),
           ec_num_data_fragments (number of fragments original
             data split into after erasure coding operation),
           ec_num_parity_fragments (number of parity fragments
           generated during erasure coding)
         . Private methods
           EC specific attributes and ring validator methods.
    
     - Swift will use PyECLib, a Python Erasure Coding library, for
       erasure coding operations. PyECLib is already an approved
       OpenStack core requirement.
       (https://bitbucket.org/kmgreen2/pyeclib/)
    
     - Add test cases for
       - 'policy_type' StoragePolicy member
       - policy_type == 'erasure_coding'

Set connection timeout in container sync
    
    Container sync might get stuck without a connection timeout if the remote proxy
    is not responding.
    
    This patch sets a default timeout of 5.0 seconds for the connection attempt. The
    value is much higher than other connection timeouts inside Swift (0.5); however
    there might be a much higher latency to the remote peer, thus playing it safe.
    There is also a retry if the attempt timed out.
    
    Note that this setting only applies to the connection request itself. Setting
    this timeout does not apply when the remote proxy goes away during a request.
    
    Also added a short test to ensure urlopen is called with the timeout value.

Add some debug output to the ring builder
    
    Sometimes, I get handed a builder file in a support ticket and a
    question of the form "why is the balance [not] doing $thing?". When
    that happens, I add a bunch of print statements to my local
    swift/common/ring/builder.py, figure things out, and then delete the
    print statements. This time, instead of deleting the print statements,
    I turned them into debug() calls and added a "--debug" flag to the
    rebalance command in hopes that someone else will find it useful.

Enable in-process functional test policy to be configured
    
    Currently the in-process tests build a 2 replica, 4 partition,
    2 device object ring. This patch allows an alternative policy
    and ring to be specified for testing via environment variables
    that may optionally be set.
    
    SWIFT_TEST_IN_PROCESS_CONF_DIR - This points the test setup to a
      directory which may have a swift.conf file and ring file. The
      test setup will then prefer these conf files over the samples
      in '/etc'.
    
    SWIFT_TEST_POLICY - This causes the in-process test to
      use the specified policy from the swift.conf file and its
      associated ring for testing (first copying the conf and ring file
      and modifying device parameters to suit in-process testing). If
      not set, the tests will use the default policy.
    
    The in-process tests now start sufficient object servers for the
    ring file being tested against.
    
    This should allow in-process functional testing of various policies
    and rings (e.g. EC policies) without needing to reconfigure an SAIO
    for each test scenario.
    
    The refactoring of the in_process test setup code should also
    allow easier addition of other 'hard-coded' test policies/rings
    in the future.

Fix a lack of method arguments at tempauth
    
    This fixes a kind of trivial issue with TypeError caused by a lack
    of method argument at calling.
    
    When using 'Authorization' header with tempauth, tempauth calls
    _get_user_groups with 3 arguments (includes self) on current code
    but the method requires 4 arguments so it will go to fail with 500.
    
    This patch fixes to take correct arguments and adds an unit test
    for the case.

Tighten up recon middleware unit tests
    
    Adds a test for get_expirer_info() and tightens up
    the test for get_async_info().
    
    While reviewing [1] I noticed that the existing tests on
    master will not catch a bug creeping into the arg strings
    that these methods pass to from_recon_cache().

Fix the prefix of messages caputured from stderr
    
    Swift caputures both sys.stdout and sys.stderr messages and
    transfers them to syslog. However, whole of the messages
    uses the "STDOUT:" prefix, currently.
    
    It will be quite confusable for debugging purpose because we
    cannot make sure whether "Swift didn't caputure stderr" or
    "Swift captured stderr but didn't show it" when we want to log
    some stderr messages.
    
    This patch enables to allow a new prefix "STDERR:" and use it
    for sys.stderr.

Allow swift-object-info to inspect .meta and .ts files

    *any* file for metadata, so it works with .meta and .ts

Fix ContainerBroker to use policy-0 in default
    
    Fix ContainerBroker to initialize as policy-0 on policy_stat
    table in default when storage_policy_index argument is NOT given.
    
    Current ContainerBroker makes policy-1 stats in default because
    the "None" value will be passed through to the last function of
    db access query (i.e. a query like as "INSERT INTO policy_stat
    (storage_policy_index) VALUES (None)" will appear) which results
    in a row "(1, 0, 0)" (the first value is the policy index) by
    the PRIMARY KEY constraint on sqlite.
    
    In worst case, container db keeps two policies, and then, ContainerBroker.get_info
    might return invalid (non-touched) policy_stat information as container information.
    (See tests in detail)
    
    When using ContainerBroker with no storage_policy_index argument,
    it should always act policy-0 simply.
    
    Note that this patch doesn't affect immediately Swift behavior because
    current swift ensures to use policy-0 on "Container-Server" when invalid
    policy (includes None) is given. However, we should recheck also in
    ContainerBroker for safety to prevent the unfortunate behavior above.
