Changelog


Version 0.7.4 (2017-03-14)

  • Resolve rare deadlock when using Stream Management
  • Rework how WebSocket connections are closed

  • Use single equals sign (“=”) for zero-length data in SASL, as per RFC 6120 § 6.4.2
  • Allow configuring a custom stream host and skip proxy discovery then for SI file transfer.
  • Implement WebSocket pings/pongs.
  • Fix WebSocket’s proxy URI construction.
  • Use connect timeout for WebSocket connections.
  • XEP-0198: Send an ack right before gracefully closing the stream (i.e. update to version 1.5.2).
  • MUC Room “enter” events should fire for oneself entering the room as well.
  • Use java.text.Collator for String-based default comparison.
  • XEP-0066: Use URI instead of URL.

Version 0.7.2 (2016-09-08)

  • Fix reconnection issue, when using multiple connection methods per session.
  • Improve and fix stanza acknowledging and Stream Management
    • Add Delayed Delivery (XEP-0203) extension to stanzas, which are resent automatically later (when reconnected again)
    • Always resent all unacknowledged stanzas after login, not only after stream resumption.
    • Highlight StreamManagement’s request / answer pairs in VisualDebugger.
    • Update XEP-0198 Stream Management to version 1.5 (respect the ‘h’ attribute in the failed element)
  • Wait for the roster response before sending initial presence during login, to prevent receiving presence information from yet unknown contacts.
  • Make sure asynchronous method calls do not block (affected only few methods for avatars and entity capabilities)
  • Use the hostname instead of the domain for SASL clients (i.e. use the Sasl.createSaslClient API correctly as per the documentation, may affect DIGEST-MD5 authentication).
  • Call SaslClient.dispose() when SASL authentication has completed.
  • Include the requesting IQ in NoResponseException, when doing IQ queries.
  • XEP-0184: Add the sender of a receipt to the MessageDeliveryEvent.
  • Allow event consumption for outbound stanzas, which prevents the stanza to be sent.
  • Make stream feature negotiation more stable.
  • Minor graphical fixes in VisualDebugger.
  • Add API to include the hash and mime type in File Transfer offers.
  • Add API to create a chat session with a thread id.

  • Add listeners to listen for successful or failed send operations.
  • Add public constructor for the SASL challenge class.
  • Add public constructors to SASL Failure class.

  • Add DataForm.Field#getValue() and implement toString() method.
  • Add convenient API to compare two MUC affiliations and roles (i.e. Affiliation.OWNER.isHigherThan(Affiliation.ADMIN))
  • Compare presences of MUC occupants in the Occupant’s Comparable implementation.
  • Minor performance improvement by using a ListIterator in collection based result sets.
  • Discover PubSub services by identity, not by feature name (it’s more reliable)
  • Add nextPage() and previousPage() method and refine the naming of other methods in result set management (e.g. having forCount() and forItemCount() was confusing)

  • Likewise the Roster and Chat classes have been moved from the ‘core’ to ‘im’ package to better resemble the separation of RFC 6120 and 6121.
  • Use Java 8’s Functional Interfaces:
    • All event listeners have been replaced by java.util.function.Consumer<T extends EventObject> (if you used lambda expressions, nothing has changed for you)

    • java.util.TimeZone has been replaced with java.time.ZoneOffset
    • java.util.Date has been replaced with java.time.OffsetDateTime or java.time.Instant
  • Reduce logging overhead by deferred string building.

  • Stanza classes refactoring:
    • Stanzas moved from rocks.xmpp.core.stanza.model.client to rocks.xmpp.core.stanza.model. This was a necessary change for XEP-0114.

    • There are new addExtension() / removeExtension() / hasExtension() methods.

Version 0.3.0 (2014-08-02)

Version 0.2.0 (2014-07-06)

  • Add JID Escaping feature (jid\\escaping) to feature list for Service Discovery.
  • Restructure the project: It’s now separated into modules:
    • xmpp-core, which contains XML schema implementations and core classes. It could theoretically be useful for a server implementation, too.
    • xmpp-client, which contains business logic, used by XMPP clients (e.g. connection logic, roster management, …)
  • The base Connection class is now called XmppSession, which can have multiple connection methods. Each connection method is tried while connecting. That way a XMPP session can have a normal TcpConnection and an alternative BoshConnection, which is tried as fallback.
