2011-09-15Session class separated into socket-type-specific sessionsMartin Sustrik
This is a preliminary patch allowing for socket-type-specific functionality in the I/O thread. For example, message format can be checked asynchronously and misbehaved connections dropped straight away. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-08-18TCP address related functionality moved to tcp_address_tMartin Sustrik
Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-08-18IPC address related functionality refactored into ipc_address_t classMartin Sustrik
Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-08-16tcp_engine renamed to stream engineMartin Sustrik
The engine was not used exclusively for TCP connections. Rather it was used to handle any socket with SOCK_STREAM semantics. The class was renamed to reflect its true function. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2011-07-24Session classes merged into a single classMartin Sustrik
Removal of ZMQ_IDENTITY resulted in various session classes doing almost the same thing. This patch merges the classes into a single class. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-07-24semaphore_t class removedMartin Sustrik
The class was not used anywhere anymore. Removed. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-07-24Remove blob_t classMartin Sustrik
The class was used in a single place. Replaced by a local typedef. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-07-21ZMQ_GENERIC renamed to ZMQ_ROUTERMartin Sustrik
Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
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. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
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. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-06-27Rename i_inout to i_engine_sinkMartin Sustrik
Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
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>

Signed-off-by: Mikko Koppanen <mkoppanen@php.net>
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
Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
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>

2010-12-04XPUB and XSUB socket types added.Martin Sustrik
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). Signed-off-by: Martin Lucina <mato@kotelna.sk>
2010-11-17Remove unnecessary conditionalMikko Koppanen
This conditional is unnecessary as BUILD_PGM can be negated in the test. Signed-off-by: Mikko Koppanen <mkoppanen@php.net>

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.
2010-06-21Add SWAP supportMartin Hurton
2010-06-17stopwatch returned to libzmqMartin Sustrik
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.
