./net/zeromq, The ZeroMQ messaging library

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 4.2.3, Package name: zeromq-4.2.3, Maintainer: pkgsrc-users

The 0MQ lightweight messaging kernel is a library which extends the
standard socket interfaces with features traditionally provided by
specialised messaging middleware products. 0MQ sockets provide an
abstraction of asynchronous message queues, multiple messaging
patterns, message filtering (subscriptions), seamless access to
multiple transport protocols and more.

zeromq: updated to 4.2.3

version 4.2.3 stable:

* API change: previously ZMQ_POLLOUT on a ZMQ_ROUTER socket returned always
  true due to how the type works. When ZMQ_ROUTER_MANDATORY is set, sending
  fails when the peer is not available, but ZMQ_POLLOUT always returns true
  anyway, which does not make sense. Now when ZMQ_ROUTER_MANDATORY is set,
  ZMQ_POLLOUT on a ZMQ_ROUTER will return true only if at least one peer is
  Given ZMQ_POLLOUT with ZMQ_ROUTER was not usable at all previously, we do
  not consider this a breakage warranting a major or minor version increase.

* ZMQ_IDENTITY has been renamed to ZMQ_ROUTING_ID and ZMQ_CONNECT_RID has been
  renamed to ZMQ_CONNTECT_ROUTING_ID to disambiguate. ZMQ_IDENTITY and
  ZMQ_CONNECT_RID are still available to keep backward compatibility, and will
  be removed in a future release after further advance notice.

* DRAFT API change: zmq_poller_wait, zmq_poller_wait_all and zmq_poller_poll
  have been changed to be inline with other existing APIs that have a timeout
  to return EAGAIN instead of ETIMEDOUT as the errno value.

* Existing non-DRAFT socket types ZMQ_REP/REQ, ZMQ_ROUTER/DEALER and
  ZMQPUB/SUB, that were previously declared deprecated, have been reinstated
  as stable and supported.

* Tweetnacl: add support for, and use preferably if available, getrandom() as
  a simpler and less error-prone alternative to /dev/urandom on OSes where it
  is available (eg: Linux 3.18 with glibc 2.25).

* Curve: all remaining traces of debug output to console are now removed, and
  new DRAFT events are available to properly debug CURVE, PLAIN, GSSAPI and
  ZAP events and failures. See below for details on the new events.

* New DRAFT (see NEWS for 4.2.0) socket options:
    the corresponding GSSAPI features. Additional definitions for principal
    name types:
    See doc/zmq_gssapi.txt for details.
  - ZMQ_BINDTODEVICE (Linux only), which will bind the socket(s) to the
    specified interface. Allows to use Linux VRF, see:
    https://www.kernel.org/doc/Documentatio … ng/vrf.txt
    NOTE: requires the program to be ran as root OR with CAP_NET_RAW
  - ZMQ_ZAP_ENFORCE_DOMAIN, enables strict RFC 27 compatibility mode and makes
    the ZAP Domain mandatory when using security. See:
  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.

* New DRAFT (see NEWS for 4.2.0) context options:
    to add and remove CPUs to the affinity set of the I/O threads. Useful to pin
    the background threads to specific CPUs.
  - ZMQ_THREAD_NAME_PREFIX (Posix only), to add a specific integer prefix to the
    background threads names, to easily identify them for debugging purposes.
  See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.

* New DRAFT (see NEWS for 4.2.0) message property name definitions to facilitate
  the use of zmq_msg_gets:
  See doc/zmq_msg_gets.txt for details.

* New DRAFT (see NEWS for 4.2.0) API zmq_socket_get_peer_state, to be used to
  query the state of a specific peer (via routing-id) of a ZMQ_ROUTER socket.

* New DRAFT (see NEWS for 4.2.0) Socket Monitor events:
  - ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL, unknown system error and returns errno
  - ZMQ_EVENT_HANDSHAKE_SUCCEEDED, handshake was successful
  - ZMQ_EVENT_HANDSHAKE_FAILED_PROTOCOL, protocol errors between peers or server
    and ZAP handler. Returns one of ZMQ_PROTOCOL_ERROR_* - see manpage for list
  - ZMQ_EVENT_HANDSHAKE_FAILED_AUTH, failed authentication, returns ZAP status
  These events trigger when the ZMTP security mechanism handshake is
  completed or failed. See doc/zmq_socket_monitor.txt for more information.

* New DRAFT (see NEWS for 4.2.0) zmq_proxy_steerable command 'STATISTICS' to
  retrieve stats about the amount of messages and bytes sent and received by
  the proxy. See doc/zmq_proxy_steerable.txt for more information.

* Add new autoconf --disable-libunwind option to stop building with libunwind
  even if it is available.

* Add new autoconf --disable-Werror option to avoid building with the Werror

* Use pkg-config as the first method for finding and building with external
  optional dependencies such as libnorm, libpgm and gssapi.

* On Posix platform where the feature is available, name the ZMQ background
  threads to simplify debugging: "ZMQbg/<num_thread>"

* Improve performance of zmq_poller_* (and zmq_poll and zmq_proxy when building
  with DRAFT APIs enabled).

* The TCP unit tests have been refactored to bind and connect to random ports
  rather than hard-coded ones, to allow running tests in parallel.
  There are 6 exceptions where it is necessary to use an hard-coded port to
  test specific code paths that would not be exercised when binding to a
  wildcard port. These are listed in tests/testutil.hpp so that distributions
  can easily patch them if they wish to and so that they can be unique across
  all the tests, allowing parallel runs.
  The IPC unit tests have been changed as well to use unique socket file names
  per test, where before there were some clashes.

* Fixed 2349 - fix building with libsodium when using CMake

Update net/zeromq to 4.2.1.

0MQ version 4.2.1 stable, released on 2016/12/31
* New DRAFT (see NEWS for 4.2.0) Socket Monitor events:
  These events trigger when the ZMTP security mechanism handshake is
  completed. See doc/zmq_socket_monitor.txt for more information.
* New DRAFT (see NEWS for 4.2.0) Context options:
  See doc/zmq_ctx_get.txt for more information.

0MQ version 4.2.0 stable, released on 2016/11/04
* For Pieter. Thanks for making all of this possible.
  "Tell them I was a writer.
   A maker of software.
   A humanist. A father.
   And many things.
   But above all, a writer.
   Thank You. :)"
   - Pieter Hintjens
* This release introduces new APIs, but it is ABI compatible with
  libzmq 4.1.2 and up.
* Note for ARM and SPARC users: an alignment problem in zmq_msg_t that could in
  some cases and on some CPUs cause a SIGBUS error was solved, but it requires
  a rebuild of your application against the 4.2.0 version of include/zmq.h.
  To clarify, this change does not affect the internals of the library but only
  the public definition of zmq_msg_t, so there is no ABI incompatibility.
* Security with Curve is now available by default thanks to Tweetnacl sources:
  Libsodium is still fully supported but has to be enabled with the build flag
  --with-libsodium. Distribution and package maintainers are encouraged to use
  libsodium so that the security implementation can be audited and maintained
* New Context options:
  See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
* New Socket options:
  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
* New CURVE helper function to derive z85 public key from secret key:
* New cross-platform atomic counter helper functions:
    zmq_atomic_counter_new, zmq_atomic_counter_set, zmq_atomic_counter_inc,
    zmq_atomic_counter_dec, zmq_atomic_counter_value, zmq_atomic_counter_destroy
  See doc/zmq_atomic_*.txt for details.
* New DRAFT APIs early-release mechanism. New APIs will be introduced early
  in public releases, and until they are stabilized and guaranteed not to
  change anymore they will be unavailable unless the new build flag
  --enable-drafts is used. This will allow developers and early adopters to
  test new APIs before they are finalized.
  NOTE: as the name implies, NO GUARANTEE is made on the stability of these APIs.
  They might change or disappear entirely. Distributions are recommended NOT to
  build with them.
  New socket types have been introduced in DRAFT state:
  All these sockets are THREAD SAFE, unlike the existing socket types. They do
  NOT support multipart messages (ZMQ_SNDMORE/ZMQ_RCVMORE).
  ZMQ_RADIO, ZMQ_DISH and ZMQ_DGRAM also support UDP as transport,
  both unicast and multicast. See doc/zmq_udp.txt for more details.
  New methods to support the new socket types functionality:
    zmq_join, zmq_leave, zmq_msg_set_routing_id, zmq_msg_routing_id,
    zmq_msg_set_group, zmq_msg_group
  See doc/zmq_socket.txt for more details.
  New poller mechanism and APIs have been introduced in DRAFT state:
    zmq_poller_new, zmq_poller_destroy, zmq_poller_add, zmq_poller_modify,
    zmq_poller_remove, zmq_poller_wait, zmq_poller_wait_all, zmq_poller_add_fd
    zmq_poller_modify_fd, zmq_poller_remove_fd
  and a new supporting struct typedef: zmq_poller_event_t
  They support existing socket type, new thread-safe socket types and file
  descriptors (cross-platform).
  Documentation will be made available in the future before these APIs are declared
  New cross-platform timers helper functions have been introduced in DRAFT state:
    zmq_timers_new, zmq_timers_destroy, zmq_timers_add, zmq_timers_cancel,
    zmq_timers_set_interval, zmq_timers_reset, zmq_timers_timeout,
  and a new supporting callback typedef: zmq_timer_fn
* Many, many bug fixes. The most important fixes are backported and captured in the
  4.1.x and 4.0.x changelogs.
