Riak CS 1.3.0 Release Notes

Bugs Fixed

  • Fix handling of cases where buckets have siblings. Previously this resulted in 500 errors returned to the client.
  • Reduce likelihood of sibling creation when creating a bucket.
  • Return a 404 instead of a 403 when accessing a deleted object.
  • Unquote URLs to accommodate clients that URL encode / characters in URLs.
  • Deny anonymous service-level requests to avoid unnecessary error messages trying to list the buckets owned by an undefined user.

Additions

  • Support for multipart file uploads. Parts must be in the range of 5MB-5GB.
  • Support for bucket policies using a restricted set of principals and conditions.
  • Support for returning bytes ranges of a file using the Range header.
  • Administrative commands may be segrated onto a separate interface.
  • Authentication for administrative commands may be disabled.
  • Performance and stability improvements for listing the contents of buckets.
  • Support for the prefix, delimiter, and marker options when listing the contents of a bucket.
  • Support for using Webmachine’s access logging features in conjunction with the Riak CS internal access logging mechanism.
  • Moved all administrative resources under /riak-cs.
  • Riak CS now supports packaging for FreeBSD, SmartOS, and Solaris.

Riak CS 1.2.2 Release Notes

Bugs Fixed

  • Fix problem where objects with utf-8 unicode key cannot be listed nor fetched.
  • Speed up bucket_empty check and fix process leak. This bug was originally found when a user was having trouble with s3cmd rb :s3//foo --recursive. The operation first tries to delete the (potentially large) bucket, which triggers our bucket empty check. If the bucket has more than 32k items, we run out of processes unless +P is set higher (because of the leak).

Additions

  • Full support for MDC replication

Riak CS 1.2.1 Release Notes

Bugs Fixed

  • Return 403 instead of 404 when a user attempts to list contents of nonexistent bucket.
  • Do not do bucket list for HEAD or ?versioning or ?location request.

Additions

  • Add reduce phase for listing bucket contents to provide backpressure when executing the MapReduce job.
  • Use prereduce during storage calculations.
  • Return 403 instead of 404 when a user attempts to list contents of nonexistent bucket.

Riak CS 1.2.0 Release Notes

Bugs Fixed

  • Do not expose stack traces to users on 500 errors
  • Fix issue with sibling creation on user record updates
  • Fix crash in terminate state when fsm state is not fully populated
  • Script fixes and updates in response to node_package updates

Additions

  • Add preliminary support for MDC replication
  • Quickcheck test to exercise the erlcloud library against Riak CS
  • Basic support for riak_test integration

Riak CS 1.1.0 Release Notes

Bugs Fixed

  • Check for timeout when checking out a connection from poolboy.
  • PUT object now returns 200 instead of 204.
  • Fixes for Dialyzer errors and warnings.
  • Return readable error message with 500 errors instead of large webmachine backtraces.

Additions

  • Update user creation to accept a JSON or XML document for user creation instead of URL encoded text string.
  • Configuration option to allow anonymous users to create accounts. In the default mode, only the administrator is allowed to create accounts.
  • Ping resource for health checks.
  • Support for user-specified metadata headers.
  • User accounts may be disabled by the administrator.
  • A new key_secret can be issued for a user by the administrator.
  • Administrator can now list all system users and optionally filter by enabled or disabled account status.
  • Garbage collection for deleted and overwritten objects.
  • Separate connection pool for object listings with a default of 5 connections.
  • Improved performance for listing all objects in a bucket.
  • Statistics collection and querying.
  • DTrace probing.

  • Correct inappropriate use of riak_moss_utils:get_user by riak_moss_acl_utils:get_owner_data

Riak CS 1.0.0 Release Notes

Bugs Fixed

  • Fix PUTs for zero-byte files
  • Fix fsm initialization race conditions
  • Canonicalize the entire path if there is no host header, but there are tokens
  • Fix process and socket leaks in get fsm

Other Additions

  • Subsystem for calculating user access and storage usage
  • Fixed-size connection pool of Riak connections
  • Use a single Riak connection per request to avoid deadlock conditions
  • Object ACLs
  • Management for multiple versions of a file manifest
  • Configurable block size and max content length
  • Support specifying non-default ACL at bucket creation time

Riak CS 0.1.2 Release Notes

Bugs Fixed

  • Return 403 instead of 503 for invalid anonymous or signed requests.
  • Properly clean up processes and connections on object requests.

Riak CS 0.1.1 Release Notes

Bugs Fixed

  • HEAD requests always result in a 403 Forbidden.
  • s3cmd info on a bucket object results in an error due to missing ACL document.
  • Incorrect atom specified in riak_moss_wm_utils:parse_auth_header.
  • Bad match condition used in riak_moss_acl:has_permission/2.

Riak CS 0.1.0 Release Notes

Bugs Fixed

  • s3cmd info fails due to missing 'last-modified key in return document.
  • s3cmd get of 0 byte file fails.
  • Bucket creation fails with status code 415 using the AWS Java SDK.

Other Additions

  • Bucket-level access control lists
  • User records have been modified so that an system-wide unique email address is required to create a user.
  • User creation requests are serialized through stanchion to be certain the email address is unique.
  • Bucket creation and deletion requests are serialized through stanchion to ensure bucket names are unique in the system.
  • The stanchion serialization service is now required to be installed and running for the system to be fully operational.
  • The concept of an administrative user has been added to the system. The credentials of the administrative user must be added to the app.config files for moss and stanchion.
  • User credentials are now created using a url-safe base64 encoding module.

Known Issues

  • Object-level access control lists have not yet been implemented.

Riak CS 0.0.3 Release Notes

Bugs Fixed

  • URL decode keys on put so they are represented correctly. This eliminates confusion when objects with spaces in their names are listed and when attempting to access them.
  • Properly handle zero-byte files
  • Reap all processes during file puts

Other Additions

Support for the s3cmd subcommands sync, du, and rb

  • Return valid size and checksum for each object when listing bucket objects.
  • Changes so that a bucket may be deleted if it is empty.

Changes so a subdirectory path can be specified when storing or retrieving files.

Make buckets private by default

Support the prefix query parameter

Enhance process dependencies for improved failure handling

Known Issues

  • Buckets are marked as private by default, but globally-unique bucket names are not enforced. This means that two users may create the same bucket and this could result in unauthorized access and unintentional overwriting of files. This will be addressed in a future release by ensuring that bucket names are unique across the system.
