0MQ version 2.1.9 (Stable), released on 2011/08/29 ================================================== Bug fixes --------- * Fixed issue 240, assertion failure in pgm_socket.cpp:437. * Fixed issue 238, assertion failure in zmq.cpp:655, when zmq_poll is used on an empty set, on Windows. * Fixed issue 239, assertion failure in zmq.cpp:223, when ZMQ_SWAP was used with explicit identities and multiple SUB sockets. * Fixed issue 236, zmq_send() and zmq_recv() did not always return error conditions such as EFSM properly. This bug was introduced in version 2.1.8 by the backport of changes for issue 231. Building -------- * 0MQ support for Android added (Bill Roberts, Mikko Koppanen). 0MQ version 2.1.8 (RC), released on 2011/07/28 ============================================== Bug fixes --------- * Fixed issue 223, assertion failure in tcp_connecter.cpp:300 when connecting to a server that is on an unreachable network (errno is equal to ENETUNREACH). * Fixed issue 228, assertion failure at rep.cpp:88 when HWM was reached. * Fixed issue 231, assertion failure at mailbox.cpp:183 when too many pending socketpair operations were queued (major backport from 3.0). * Fixed issue 234, assertion failure at mailbox.cpp:77 when Ctrl-C was used (only affected git master following backport for 231). * Fixed issue 230, SIGPIPE killing servers when client disconnected, hit OS/X only. Note: this release was renamed "release candidate" due to issue 236, fixed in 2.1.9. 0MQ version 2.1.7 (Stable), released on 2011/05/12 ================================================== Bug fixes --------- * Fixed issue 188, assert when closing socket that had unread multipart data still on it (affected PULL, SUB, ROUTER, and DEALER sockets). * Fixed issue 191, message atomicity issue with PUB sockets (an old issue). * Fixed issue 199 (affected ROUTER/XREP sockets, an old issue). * Fixed issue 206, assertion failure in zmq.cpp:223, affected all sockets (bug was introduced in 2.1.6 as part of message validity checking). * Fixed issue 211, REP socket asserted if sent malformed envelope (old issue due to abuse of assertions for error checking). * Fixed issue 212, reconnect failing after resume from sleep on Windows (due to not handling WSAENETDOWN). * Properly handle WSAENETUNREACH on Windows (e.g. if client connects before server binds). * Fixed memory leak with threads on Windows. Changes ------- * Checks zmq_msg_t validity at each operation. * Inproc performance tests now work on Windows. * PGM wire format specification improved in zmq_pgm(7) * Added thread latency/throughput performance examples. * Added "--with-system-pgm" configure option to use already installed OpenPGM. * Runtime checking of socket and context validity, to catch e.g. using a socket after closing it, or passing an invalid pointer to context/socket methods. * Test cases moved off port 5555, which conflicts with other services. * Clarified zmq_poll man page that the resolution of the timeout is 1msec. 0MQ version 2.1.6 (Broken), released on 2011/04/26 ================================================== Note that this version contained a malformed patch and is not usable. It is not available for download, but is available in the git via the 2.1.6 tag. 0MQ version 2.1.5 (Broken), released on 2011/04/20 ================================================== Note that this version contained a malformed patch and is not usable. It is not available for download, but is available in the git via the 2.1.5 tag. 0MQ version 2.1.4 (Stable), released on 2011/03/30 ================================================== Bug fixes --------- * Fix to OpenPGM which was asserting on small messages (Steven McCoy). Changes ------- * Upgraded OpenPGM to version 5.1.115 (Pieter Hintjens). * OpenPGM build changed to not install OpenPGM artifacts. 0MQ version 2.1.3 (Stable), released on 2011/03/21 ================================================== Bug fixes --------- * Fix to PUSH sockets, which would sometimes deliver tail frames of a multipart message to new subscribers (Martin Sustrik). * Fix to PUB sockets, which would sometimes deliver tail frames of a multipart message to new subscribers (Martin Sustrik). * Windows build was broken due to EPROTONOSUPPORT not being defined. This has now been fixed (Martin Sustrik). * Various fixes to make OpenVMS port work (Brett Cameron). * Corrected Reference Manual to note that ZMQ_LINGER socket option may be set at any time, not just before connecting/binding (Pieter Hintjens). * Fix to C++ binding to properly close sockets (Guido Goldstein). * Removed obsolete assert from pgm_socket.cpp (Martin Sustrik). Changes ------- * Removed stand-alone devices (/devices subdirectory) from distribution. These undocumented programs remain available in older packages (Pieter Hintjens). * OpenPGM default rate raised to 40mbps by default (Steven McCoy). * ZMQ_DEALER and ZMQ_ROUTER macros provided to ease upgrade to 0MQ/3.0. These are scheduled to replace ZMQ_XREQ and ZMQ_XREP (Pieter Hintjens). * Added man page for zmq_device(3) which was hereto undocumented (Pieter Hintjens). * Removed zmq_queue(3), zmq_forwarder(3), zmq_streamer(3) man pages (Pieter Hintjens). OpenPGM Integration ------------------- * Upgraded OpenPGM to version 5.1.114 (Steven McCoy, Mikko Koppanen). * Build system now calls OpenPGM build process directly, allowing easier future upgrades of OpenPGM (Mikko Koppanen). * Build system allows configuration with arbitrary versions of OpenPGM (./configure --with-pgm=libpgm-x.y.z) (Mikko Koppanen). * OpenPGM uses new PGM_ODATA_MAX_RTE controlling original data instead of PGM_TXW_MAX_RTE covering entire channel (Steven McCoy). Building -------- * 0MQ builds properly on FreeBSD (Mikko Koppanen). 0MQ version 2.1.2 (rc2), released on 2011/03/06 =============================================== Bug fixes --------- * 0MQ now correctly handles durable inproc sockets; previously it ignored explicit identities on inproc sockets. * Various memory leaks were fixed. * OpenPGM sender/receiver creation fixed. 0MQ version 2.1.1 (rc1), released on 2011/02/23 =============================================== New functionality ----------------- * New socket option ZMQ_RECONNECT_IVL_MAX added, allows for exponential back-off strategy when reconnecting. * New socket option ZMQ_RECOVERY_IVL_MSEC added, as a fine-grained counterpart to ZMQ_RECOVERY_IVL (for multicast transports). * If memory is exhausted, 0MQ warns with an explicit message before aborting the process. * Size of inproc HWM and SWAP is sum of peers' HWMs and SWAPs (Douglas Greager, Martin Sustrik). Bug fixes --------- * 0MQ no longer asserts in mailbox.cpp when multiple peers connect with the same identity. * 0MQ no longer asserts when rejecting an oversized message. * 0MQ no longer asserts in pipe.cpp when the swap fills up. * zmq_poll now works correctly with an empty poll set. * Many more. Building -------- * 0MQ now builds correctly on CentOS, Debian 6, and SunOS/gcc3. * Added WithOpenPGM configuration into MSVC builds. Known issues ------------ * OpenPGM integration is still not fully stable. 0MQ version 2.1.0 (Beta), released on 2010/12/01 ================================================ New functionality ----------------- * New semantics for zmq_close () and zmq_term () ensure that all messages are sent before the application terminates. This behaviour may be modified using the new ZMQ_LINGER socket option; for further details refer to the reference manual. * The new socket options ZMQ_FD and ZMQ_EVENTS provide a way to integrate 0MQ sockets into existing poll/event loops. * Sockets may now be migrated between OS threads, as long as the application ensures that a full memory barrier is issued. * The 0MQ ABI exported by libzmq.so has been formalised; DSO symbol visibility is used on supported platforms to ensure that only public ABI symbols are exported. The library ABI version has been set to 1.0.0 for this release. * OpenPGM has been updated to version 5.0.92. This version no longer depends on GLIB, and integration with 0MQ should be much improved. * zmq_poll() now honors timeouts precisely, and no longer returns if no events are signaled. * Blocking calls now return EINTR if interrupted by the delivery of a signal; this also means that language bindings which previously had problems with handling SIGINT/^C should now work correctly. * The ZMQ_TYPE socket option was added; this allows retrieval of the socket type after creation. * Added a ZMQ_VERSION macro to zmq.h for compile-time API version detection. * The ZMQ_RECONNECT_IVL and ZMQ_BACKLOG socket options have been added. Bug fixes --------- * Forwarder and streamer devices now handle multi-part messages correctly. * 0MQ no longer asserts when malformed data is received on the wire. * 0MQ internal timers now work correctly if the TSC jumps backwards. * The internal signalling functionality (mailbox) has been improved to automatically resize socket buffers on POSIX systems. * Many more. Building -------- * 0MQ now builds correctly with many more non-GCC compilers (Sun Studio, Intel ICC, CLang). * AIX and HP-UX builds should work now. * FD_SETSIZE has been set to 1024 by default for MSVC builds. * Windows builds using GCC (MinGW) now work out of the box. Distribution ------------ * A simple framework for regression tests has been added, along with a few basic self-tests. The tests can be run using "make check".
