centrifuge

[0.15.0]

• Update web_socket_channel, min SDK is now 3.3 #91
• Support headers emulation. Also added setHeaders method to update headers #92.

This release changes headers in ClientConfig from Map<String, dynamic> to Map<String, String>. This is a breaking change, but it must not cause huge troubles beyond a simple refactoring.

Usages of dart.html were removed in this release. Also some internal optimizations were done to allocate less when constructing Protobuf command data.

[0.14.1]

• Add callback to update connection data #88

[0.14.0]

• connInfo and chanInfo for join/leave events by @hetao29 #84

[0.13.0]

• Relax Protobuf dependency requirements to be >=2.0.0 <4.0.0 instead of ^3.0.0

[0.12.0]

• Fix websocket usage in web env (fixes The method 'sendByteBuffer' isn't defined for the type 'WebSocket' error), add simple web example #85

[0.11.0]

• Update protobuf dependency from ^2.0.0 to ^3.0.0. Requires Dart 2.19

[0.10.0]

Breaking change! This release changes the semantics of working with connection tokens described in Centrifugo v5 release post.

Previously, returning an empty token string from getToken callback resulted in client disconnection with unauthorized reason.

Now returning an empty string from getToken is a valid scenario which won't result into disconnect on the client side. It's still possible to disconnect client by throwing a special UnauthorizedException from getToken function.

And we are putting back setToken method to the SDK – so it's now possible to reset the token to be empty upon user logout.

[0.9.4]

• Improving reconnect behaviour upon bad network conditions (like connect timeout), #79
• #79 also handles ClientDisconnectedError in _onPing method, addresses #76

[0.9.3]

• Add support for web platform – #73

[0.9.2]

• Fix null check for close reason, fixes #66
• Close subscription streams on remove #67

[0.9.1]

• Fix setting initial connection token
• Fix setting connection data
• Fix LateInitializationError if transport is not initialized yet
• Better string representation of UnsubscribedEvent

[0.9.0]

Breaking changes

This release adopts a new iteration of Centrifugal protocol and a new iteration of API. Client now behaves according to the client SDK API specification. The work has been done according to Centrifugo v4 roadmap.

Check out Centrifugo v4 release post that covers the reasoning behind changes.

All the current core features of Centrifugal client protocol are now supported here.

New release only works with Centrifugo >= v4.0.0 and Centrifuge >= 0.25.0. See Centrifugo v4 migration guide for details about the changes in the ecosystem.

Note, that Centrifugo v4 supports clients working over the previous protocol iteration, so you can update Centrifugo to v4 without any changes on the client side (but you need to turn on use_client_protocol_v1_by_default option in the configuration of Centrifugo, see Centrifugo v4 migration guide for details).

[0.8.0]

Version 0.8.0 is the next iteration of centrifuge-dart development. It pushes client closer to other clients in the ecosystem. It also contains several backwards incompatible changes.

• Return Futures from Client.connect, Client.disconnect, Subscription.subscribe, Subscription.unsubscribe methods - addresses #31.
• On initial connect fire DisconnectEvent on connection error - this makes behavior of centrifuge-dart similar to all other our clients - addresses #56.
• Add client error stream to consume ErrorEvent - each transport failure will emit error to this stream - addresses #56.
• Refactor subscription statuses - add subscribing and error statuses. This change is mostly internal should not affect working with Subscriptions.
• Do not call UnsubscribeEvent if subscription is not successfully subscribed (i.e. in subscribed state). This makes behavior of centrifuge-dart similar to all other our clients.
• Update disconnect reasons due to failed connection and calling Client.Disconnect method - make it more similar to all other connector libraries in ecosystem.
• Add default transport timeout (10 sec) – on connect and subscribe timeouts client will auto reconnect, calls like publish, history, rpc can now throw TimeoutException. Also - properly pass timeout to the transport (was not before!). Again – this makes client behave similarly to all other connectors.
• Add presence and presenceStats methods for Subscription and on client top level (for server-side subscriptions).
• Support streamPosition in SubscribeSuccessEvent.
• Support streamPosition in ServerSubscribeEvent.
• Support data in ServerSubscribeEvent.
• Implement send method to send async messages to a server.
• Fix deletion during iteration over map when working with server-side subscriptions.
• Better event String representations.
• Improvements and fixes in examples.

[0.7.1]

• Add support for data in SubscribeSuccessEvent. This is a custom data which can be sent by a server towards client connection in subscribe result. Note that due to the bug in Centrifugo server this feature only works in Centrifugo >= v3.0.3.

[0.7.0]

Update to work with Centrifuge >= v0.18.0 and Centrifugo v3.

Breaking change in server behavior. Client History API behavior changed in Centrifuge >= v0.18.0 and Centrifugo >= v3.0.0. When using history call it won't return all publications in a stream by default. See Centrifuge v0.18.0 release notes or Centrifugo v3 migration guide for more information and workaround on server-side.

• Protocol definitions updated to the latest version
• History method now accepts optional limit, since and reverse arguments and returns HistoryResult
• RPC call now requires method name as first argument (you can pass empty string to mimic previous behavior)
• Publish now returns PublishResult
• When working with Centrifugo v3 or Centrifuge >= v0.18.0 it's now possible to avoid using ?format=protobuf in connection URL. Client will negotiate Protobuf protocol with a server using WebSocket subprotocol mechanism (in request headers).

[0.6.0]

Null safety migration

• library dependencies updated to null safe versions
• library code updated to support null safety in places where required

See issue #47 and pull request #48 for details.

[0.5.1]

• Skip handling for events from server-side subscriptions resulted in null pointer dereference

[0.5.0]

• Update protobuf dependency to ^1.0.1, thanks @Holofox

[0.4.1]

• Implement removeSubscription method, thanks @tiamo

[0.4.0]

[0.3.0]

• Breaking changes Changed API to avoid returning futures where they do not make sense – in connect and subscribe methods.
• Client now uses Websocket Ping/Pong frames to find broken connection
• Support for private channel subscription using onPrivateSub configuration callback function
• Fix several null pointer dereferences in edge cases, throw ClientDisconnectedError when there is an attempt to send protocol request over non-connected client.
• Fix examples where subscribe could happen before stream handlers set

• Added reconnection.
• Added history method to Subscription. Thanks vanelizarov.
