From 05d908492dc382941fc633ad7082b5bd86e84e67 Mon Sep 17 00:00:00 2001 From: Martin Sustrik Date: Fri, 6 Aug 2010 17:49:37 +0200 Subject: WIP: Socket migration between threads, new zmq_close() semantics 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. --- src/io_thread.cpp | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'src/io_thread.cpp') diff --git a/src/io_thread.cpp b/src/io_thread.cpp index fac6961..3d202cf 100644 --- a/src/io_thread.cpp +++ b/src/io_thread.cpp @@ -26,9 +26,8 @@ #include "err.hpp" #include "ctx.hpp" -zmq::io_thread_t::io_thread_t (ctx_t *ctx_, - uint32_t thread_slot_) : - object_t (ctx_, thread_slot_) +zmq::io_thread_t::io_thread_t (ctx_t *ctx_, uint32_t slot_) : + object_t (ctx_, slot_) { poller = new (std::nothrow) poller_t; zmq_assert (poller); -- cgit v1.2.3
