2011-07-17GENERIC socket type and COMMAND flag addedMartin Sustrik
GENERIC allows to use 0MQ as a dumb networking framework. It provides user with connect/disconnect notifications. Also, each inbound message is labeled by ID of the connection it originated from. Outbound messages should be labeled by the ID of the connection to send them to. To distinguish connect/disconnect notifications from common messages, COMMAND flag was introduced.

2011-07-15ZMQ_IDENTITY socket option removedMartin Sustrik
This patch simplifies the whole codebase significantly, including dropping depedency on libuuid. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-07-15ROUTER and DEALER sockets removedMartin Sustrik
To be replaced by new generic socket type Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-07-03Command are now stored in ypipes instead of in socketpairsMartin Sustrik
Storing commands in OS socket buffers caused whole lot of problems when free space in the buffer ran out. This patch stores commands in ypipes instead and uses socketpair just to signal the other thread, ie. at most one byte is stored in the socketpair at any single instant.

2011-06-22New wire format for REQ/REP patternMartin Sustrik
This patch introduces two changes: 1. 32-bit ID is used to identify the peer instead of UUID 2. REQ socket seeds the label stack with unique 32-bit request ID It also drops any replies with non-matching request ID Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2011-03-24SWAP functionality removedMartin Sustrik
On-disk storage should be implemented in devices rather than in 0MQ core. 0MQ is a networking library and there's no point in storing network buffers on disk. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-03-24C++ binding removed from the coreMartin Sustrik

2011-03-23zmq_device removedMartin Sustrik
Devices are basically applications on top of 0MQ stack. They should reside in separate libraties. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-02-09Initial implementation of reaper thread.Martin Sustrik
Reaper thread destroys the socket asynchronously. zmq_term() can be interrupted by a signal (EINTR). zmq_socket() will return ETERM after zmq_term() was called. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

These are just placeholders. At the moment XPUB behaves th same as PUB and XSUB as SUB. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2010-11-25Control symbol exports using -fvisibilityMartin Lucina
On systems using GCC 4.0 or newer which support symbol visibility in shared libraries, use -fvisibility=hidden and only export explict API functions defined in zmq.cpp. We do not enable -fvisibility on MinGW since this uses a separate mechanism (__declspec).

2010-11-05signaler renamed to mailboxMartin Sustrik
For historical reasons queue to transfer commands between threads was called 'signaler'. Given that it was used to pass commands rather than signals it was renamed to 'mailbox', see Erlang mailboxes. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2010-08-25WIP: Socket migration between threads, new zmq_close() semanticsMartin Sustrik
Sockets may now be migrated between OS threads; sockets may not be used by more than one thread at any time. To migrate a socket to another thread the caller must ensure that a full memory barrier is called before using the socket from the target thread. The new zmq_close() semantics implement the behaviour discussed at: http://lists.zeromq.org/pipermail/zeromq-dev/2010-July/004244.html Specifically, zmq_close() is now deterministic and while it still returns immediately, it does not discard any data that may still be queued for sending. Further, zmq_term() will now block until all outstanding data has been sent. TODO: Many bugs have been introduced, needs testing. Further, SO_LINGER or an equivalent mechanism (possibly a configurable timeout to zmq_term()) needs to be implemented.
2010-08-04Renamed ZMQ_UPSTREAM to ZMQ_PULL, and ZMQ_DOWNSTREAM to ZMQ_PUSH. Left the oldPieter Hintjens
definitions as aliases, to be removed in release 3.0. Also renamed the source files implementing these two socket types. This change does not break existing applications nor bindings, but allows us to fix the documentation and user guide now, rather than keeping the old (confusing) names.

2010-05-10OpenPGM build flags cleanupMartin Lucina
Removed various exotic -Wxxx flags in the OpenPGM build to get us to what is actually required and reasonable; added in -fno-strict-aliasing since OpenPGM generates lots of warnings about dereferencing typed-punned pointers; removed the OpenPGM extra flags from libzmq_la_CXXFLAGS and left them only in libzmq_la_CFLAGS so that our code is not built with the OpenPGM extra flags.

2010-04-10Build fixes for Solaris and non-GNU compilersMartin Lucina
Compiling C++ code with -D_POSIX_SOURCE on Solaris is unsupported, so remove it. Isolate GCC-isms inside checks that we are actually using GCC/G++. Only check for -lstdc++ when on GCC and doing static linking.
