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.

2011-03-24send/recv was changed to send/recv/sendmsg/recvmsgMartin Sustrik
send/recv now complies with POSIX by using raw buffers instead of message objects and by returning number of bytes sent/recvd instead of 0/-1. The return value is changed accordingly for sendmsg and recvmsg. Note that related man pages will be fixed in a separate patch. 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).

2010-09-30zmq_poll(): Fix busy-loop if timeout is zeroMartin Lucina
Fix a case where zmq_poll() (poll-based version) could go off into a busy-loop if no revents are returned and the timeout passed in is zero.
2010-09-30 * Add assertions to check for OpenPGM calls with invalid parameters.Steven McCoy
* Assertion to check that pgm_getaddrinfo is actually returning something. * Missing pgm_connect call. * Typo on TOS causing immediate abort. * Placeholder calls for timeouts whilst continuing spin loop functionality. * OpenPGM v5 now supports reference counting so remove init checks. * Duplicate UDP unicast port setting, requires one unicast and one multicast. * Incorrectly set socket rcvbuf size with sndbuf. * Replace std::lexicographical_compare of TSI's with long word integer comparisons. * pgm_socket_t::receive returns -1 on no data.

2010-08-25zmq_poll(): Fix some corner casesMartin Lucina
Trying to optimize out the case where items_[i]. events is 0 would result in a bogus pollfds[i]. Similarly in the select()-based impl, while not strictly necessary it's better to get ZMQ_FD even if events is 0 since that detects ETERM and friends.
2010-08-25zmq_poll(): Rewrite to use ZMQ_FD/ZMQ_EVENTS pt2Martin Lucina
Rewrite the select()-based zmq_poll() implementation to use ZMQ_FD and ZMQ_EVENTS. Also fix some corner cases: We should not pollute revents with unrequested events, and we don't need to poll on ZMQ_FD at all if a pollitem with no events set was passed in.

2010-08-25zmq_poll(): Rewrite to use ZMQ_FD/ZMQ_EVENTS pt1Martin Lucina
Rewrite zmq_poll() to use ZMQ_FD and ZMQ_EVENTS introduced on the wip-shutdown branch. Only do the poll()-based version of zmq_poll (), the select()-based version will not compile at the moment.
