JeroMQ v0.4.3 Release Notes

Release Date: 2017-11-17 // over 6 years ago

  • ➕ Added

    • #470: Added an argument to the ZBeacon constructor to configure datagram socket blocking behavior. The default behavior (non-blocking) is preserved when the argument is omitted.

    • #474, #475, #477, #479 Added features:

      • ZAuth, an actor that manages authentication and handles ZAP requests.
      • ZCert, an abstraction for CURVE certificates.
      • ZCertStore, a sub-optimal store for certificates.
      • ZConfig, to manage the ZPL file format.
      • ZMonitor, for simplified socket monitoring.
      • Reinstated support for the ZMQ_MSG_ALLOCATOR option. Added a setMsgAllocator method in the ZMQ class for setting a custom message allocator.

    • #477: Added an overload of ZAgent.recv that takes a timeout argument.

    • #498: Implemented Closable for ZMQ.Poller, providing a way to call .close() on a poller when you're done with it and free the selector resource to avoid memory leaks.

    It is recommended that you either close a poller or terminate the context when you are done polling.

    🔄 Changed

    • 📚 Miscellaneous Javadoc documentation tweaks/fixes.

    • #453, #462, #471: Fixed Android-specific compilation issues.

    • 🛠 #454: Fixed an issue where the router was interpreting peers' socket identities as UTF-8 strings instead of raw bytes.

    • 🛠 #460: Fixed an issue where CURVE keys were being parsed as strings.

    • #461, #501: Fixed protocol handshake issues that were causing interoperability problems between applications using different versions of ZeroMQ/JeroMQ.

    • 🛠 #465 Various small fixes:

      • Fixed an uncaught divide by zero exception (#447).
      • ZMQ.Socket class is no longer final.
      • Handle interrupt caused by close in ZBeacon.

    • #468: Fix an issue where sockets would disconnect when network connection was lost.

    • 🛠 #469 Various small fixes:

      • Fixed an error in comparison of byte arrays in the Mechanism class.
      • Handled the possibility of receiving a null message in ZSocket by returning null instead of throwing an uncaught NullPointerException.
      • Fixed the return value of ZMQ.setHWM, which indicates the status of the lower-level calls to set the send and receive HWM, but was doing so incorrectly.

    • 🛠 #478: Fixed an issue where, when using an XPUB/XSUB proxy, the PUB socket was throwing an error when attempting to send a message if all of the subscriptions have been removed.

    • #479: Various internal improvements.

    • 🛠 #486: Fixed an issue where it was not possible to send two messages in a row without a successful receive in between, even with the RELAXED option set on the REQ socket.

    • #487 Various improvements:

      • Added some method name aliases for compatibility with the jzmq API, in places where the JeroMQ method names differed.
      • Miscellaneous internal refactoring to make JeroMQ code more similar to that of jzmq.
      • It is not possible to get the values of the ZMQ options ZMQ_REQ_CORRELATE and ZMQ_REQ_RELAXED, so getReqCorrelated and getReqRelaxed are now deprecated and will throw an UnsupportedOperationException when called.

    • 🛠 #492: Fixed an issue where a NullPointerException was thrown when trying to bind on an already used port, for example when the socket has a monitor.

    • #502: Use explicit mutex locks to help prevent problems caused by concurrent access to a ZContext. This makes ZContext behave more like libzmq's zctx.
