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/sub.hpp | 11 +++-------- 1 file changed, 3 insertions(+), 8 deletions(-) (limited to 'src/sub.hpp') diff --git a/src/sub.hpp b/src/sub.hpp index 7b997c9..da69892 100644 --- a/src/sub.hpp +++ b/src/sub.hpp @@ -33,7 +33,7 @@ namespace zmq { public: - sub_t (class app_thread_t *parent_); + sub_t (class ctx_t *parent_, uint32_t slot_); ~sub_t (); protected: @@ -41,16 +41,11 @@ namespace zmq // Overloads of functions from socket_base_t. void xattach_pipes (class reader_t *inpipe_, class writer_t *outpipe_, const blob_t &peer_identity_); - void xdetach_inpipe (class reader_t *pipe_); - void xdetach_outpipe (class writer_t *pipe_); - void xkill (class reader_t *pipe_); - void xrevive (class reader_t *pipe_); - void xrevive (class writer_t *pipe_); + void xterm_pipes (); + bool xhas_pipes (); int xsetsockopt (int option_, const void *optval_, size_t optvallen_); - int xsend (zmq_msg_t *msg_, int flags_); int xrecv (zmq_msg_t *msg_, int flags_); bool xhas_in (); - bool xhas_out (); private: -- cgit v1.2.3
