2011-04-29Substantial simplification of uuid_tMartin Sustrik
The string format of UUID is not used in 0MQ. Further on, it turns out that UUIDs have fixed microarchitecture-agnostic binary layout (see RFC4122). Thus, the conversion to string and back to binary can be avoided. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-04-21Message-related functionality factored out into msg_t class.Martin Sustrik
This patch addresses serveral issues: 1. It gathers message related functionality scattered over whole codebase into a single class. 2. It makes zmq_msg_t an opaque datatype. Internals of the class don't pollute zmq.h header file. 3. zmq_msg_t size decreases from 48 to 32 bytes. That saves ~33% of memory in scenarios with large amount of small messages.

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>

The identity of bound socket was not used. Instead, transient identity was generated. Signed-off-by: Martin Sustrik <sustrik@250bpm.com>
2011-02-25Socket with no owner objects is deallocated immediatelyMartin Sustrik
Till now the deallocation of such socket was delayed till zmq_term() thus creating a "leak". 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>

2010-11-12Fix socket_t::recv() hang scenario where initial call to process_commands() ↵Marc Rossi
eats signal Added block boolean var to second process_commands() invocation for blocking sockets instead of always using true. This prevents the process_commands() call from hanging when a message is received with an empty queue after the call to xrecv() but prior to the initial call to process_commands() invoked when ++ticks == inbound_poll_rate.

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>
2010-11-05slots renamed to tidsMartin Sustrik
Threads were so far identified by integers called 'slots'. This patch renames them to more comprehensible 'tid's (thread IDs). Signed-off-by: Martin Sustrik <sustrik@250bpm.com>

2010-10-16ZMQ_LINGER socket option added.Martin Sustrik
1. ZMQ_LINGER option can be set/get 2. options are part of own_t base class rather than being declared separately by individual objects 3. Linger option is propagated with "term" command so that the newest value of it is used rather than the stored old one. 4. Session sets the linger timer if needed and terminates as soon as it expires. 5. Corresponding documentation updated. 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.
