Changelog

v0.4.4 (unreleased)

v0.4.3 (2017-11-17)

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.

v0.4.2 (2017-06-29)

  • #443: Fix issue where JeroMQ was broken on Android. Security no longer depends on libsodium and is now pure Java

v0.4.1 (2017-06-28)

Added

JeroMQ is now based off of 4.1.7 of libzmq which means it now supports additional security features.

Changed

  • #413: fixed a NullPointerException when ZMQ.ZMQ_TCP_ACCEPT_FILTER is used

  • #412: tcp accept filter null pointer exception fix

v0.4.0 (2017-03-22)

Added

  • #366: support for ZMQ_REQ_RELAXED and ZMQ_REQ_CORRELATE socket options

  • #375: re-added ZMQ.Socket.disconnect, which had been removed in 0.3.6 because the contributor who originally added it did not agree to the license change from LGPL to MPLv2

Changed

  • #374:

    • fixed a NullPointerException and mangling of existing indexes in ZMQ.Poller
    • fixed a Windows bug in Signaler
    • other small changes to keep JeroMQ in sync with jzmq

  • #386: improved deallocation of polling Selector resources. When creating a poller via ZMQ.Context.poller or ZContext.createPoller, the context will manage the Selector resources and ensure that they are deallocated when the context is terminated.

  • #387: (BREAKING CHANGE) It is no longer possible to create a ZMQ.Poller in any way except via a context. This is to ensure that all Selector resources are deallocated when a context is terminated.

  • #388 ZMQ.Socket.setLinger can now be called safely after a context is terminated.

  • #390: fixed a bug where terminating a context while polling would sometimes cause a ClosedChannelException.

  • #399: fixed a NullPointerException that would sometimes occur when terminating a context

  • #400: (BREAKING CHANGE)

    • deprecated the setters setIoThreads, setMain and setContext in ZContext. These parameters are set in the constructor and final. Because it is no longer possible to set these values after constructing a ZContext, the setters are now no-ops.

  • #402: added constructors for ZPoller that take a ZContext argument, thus making it possible to create a ZPoller whose Selector resources are managed by the context.

v0.3.6 (2016-09-27)

Added

  • #292: support for ZMQ_XPUB_NODROP and ZMQ_XPUB_VERBOSE_UNSUBSCRIBE options

  • #299: a setter for UncaughtExceptionHandlers in ZBeacon threads

  • #309: MsgAllocator allows you to define how Msgs are allocated.

  • #316: ZSocket high-level API allows you to work with sockets directly without having to manage the ZMQ context.

Changed

  • JeroMQ no longer supports Java 6.

  • Changed from LGPL to MPLv2 license.

  • Related to changing license, the following changes were made as a result of reverting pre-0.3.6 commits by contributors who did not agree to the license change:

  • #266: fixed a NullPointerException bug in ZMsg.dump when attempting to dump a ZMsg after its frames have been cleared

  • #271, #272: misc fixes and improvements to ZAgent, ZActor, ZProxy, and ZStar

  • #295: renamed ZMQ.Socket.setRouterHandlover to ZMQ.Socket.setRouterHandover (typo fix)

  • #301: fixed a bug where if a frame failed to send, it would still try to send the next frame

  • #306, #308, #311: misc byte buffer performance improvements and bugfixes

  • #324: implementation changes to avoid extra bytes being copied in PUB/SUB
