    ๐Ÿš€ Release notes

    ๐Ÿ”– Version incompatibility in protocol

    Since 0.4.0 introduces a new node/member state, 0.4.0 is not backwards-compatible with previous versions.

    โฌ†๏ธ Note rolling upgrades with older versions do work, but undefined behaviour will occur if two versions run in parallel for longer than the FaultyPeriod (default 24 hours).

    ๐Ÿ”„ Changes to Bootstrap

    ๐Ÿš€ This release contains a breaking change to the options provided to the ringpop.Bootstrap call.

    BootstrapOptions.File and BootstrapOptions.Hosts have been replaced with BootstrapOptions.DiscoverProvider. DiscoverProvider is an interface which requires a single method:

    type DiscoverProvider interface {
        Hosts() ([]string, error)
    }
    

    Ringpop comes with DiscoverProviders for the previous File and Hosts options out of the box.

    โฌ†๏ธ To upgrade if you were previously using File:

    +       "github.com/uber/ringpop-go/discovery/jsonfile"
    ...
    -       bootstrapOpts.File = *hostfile
    +       bootstrapOpts.DiscoverProvider = jsonfile.New(*hostfile)
    

    For static Hosts:

    +       "github.com/uber/ringpop-go/discovery/statichosts"
    ...
    -       bootstrapOpts.Hosts = []string{"127.0.0.1:3000", "127.0.0.1:3001"}
    +       bootstrapOpts.DiscoverProvider = statichosts.New("127.0.0.1:3000", "127.0.0.1:3001")

    ๐Ÿš€ Release notes

    ๐Ÿš€ There are a significant number of breaking changes in this release:

    • ๐Ÿ“š Ringpop constructor has been renamed from Ringpop.NewRingpop to ringpop.New(app string, opts ...Option) and now accepts optional functional arguments. See the package documentation for a list of options.
    • ๐Ÿšš ringpop.Bootstrap now accepts swim.BootstrapOptions. ringpop.BootstrapOptions has been removed.
    • Many public methods now return an error if they are called before the ring is bootstrapped. Signatures for the changed methods are:
      • Bootstrap(opts *swim.BootstrapOptions) ([]string, error)
      • Checksum() (uint32, error)
      • Lookup(key string) (string, error)
      • LookupN(key string, n int) ([]string, error)
      • Uptime() (time.Duration, error)
      • WhoAmI() (string, error)
    • โœ‚ Removed public method ringpop.Destroyed(). Use the new ringpop.Ready() to determine if the ring is ready or not.
    • ๐Ÿ“ฆ Events moved to ringpop.events package. This includes:
      • EventListener
      • RingChangedEvent
      • RingChecksumEvent
      • LookupEvent
    • The behaviour of creating a single-node cluster has changed. Calling Bootstrap() with no bootstrap file or hosts will now cause Ringpop to create a single-node cluster.
  • v0.1

    • ๐ŸŽ‰ Initial public release
