  🚀 Release notes

  🔖 Version incompatibility in protocol

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

  ⬆️ 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).

  🔄 Changes to Bootstrap

  🚀 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.

  ⬆️ 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")

  🚀 Release notes

  🚀 There are a significant number of breaking changes in this release:

  • 📚 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.
  • 🚚 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)
  • ✂ Removed public method ringpop.Destroyed(). Use the new ringpop.Ready() to determine if the ring is ready or not.
  • 📦 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.
