      Added support for non-zmq tcp client connections to router socket. · 83387b40
      Hardeep authored
          - Created a new option ZMQ_ROUTER_RAW_SOCK
          - Added new raw_encoder and raw_decoder to receive and send messages in raw form to remote client
          - Added test case file tests/test_raw_sock.cpp
      
          o To create a raw router sock set the ZMQ_ROUTER_RAW_SOCK option
          o ZMQ_MSGMORE flag is ignored for non-id messages
          o To terminate a remote connection send id message followed by zero length data message

      Allow blocking while connect() is completing · e5904e63
      Ian Barber authored
      This patch, salvaged from a trainwreck accidental merge earlier, adds a
      new sockopt, ZMQ_DELAY_ATTACH_ON_CONNECT which prevents a end point
      being available to push messages to until it has fully connected, making
      connect work more like bind. This also applies to reconnecting sockets,
      which may cause message loss of in-queue messages, so it is sensible to
      use this in conjunction with a low HWM and potentially an alternative
      acknowledgement path.
      
      Notes on most of the individual commits can be found the repository log.

      Revert "After speaking with Ben Gray and the discussion on the mailing list, this is an attempt to create a sockopt to allow connecting pipes to not immediately be available for traffic. The problem is in a PUSH to many PULL situation, where there is a connect to a PULL which is not there. This connect will immediately create a pipe (unlike bind), and traffic will be load balanced to that pipe. This means if there is a persistently unavailable end point then the traffic will queue until HWM is hit, and older messages will be lost."

      After speaking with Ben Gray and the discussion on the mailing list, this is an attempt to create a sockopt to allow connecting pipes to not immediately be available for traffic. The problem is in a PUSH to many PULL situation, where there is a connect to a PULL which is not there. This connect will immediately create a pipe (unlike bind), and traffic will be load balanced to that pipe. This means if there is a persistently unavailable end point then the traffic will queue until HWM is hit, and older messages will be lost.
      
      This patch adds a sockopt ZMQ_DELAY_ATTACH_ON_CONNECT, which if set to 1 will attempt to preempt this behavior. It does this by extending the use of the session_base to include in the outbound as well as the inbound pipe, and only associates the pipe with the socket once it receives the connected callback via a process_attach message. This works, and a test has been added to show so, but may introduce unexpected complications. The shutdown logic in this class has become marginally more awkward because of this, requiring the session to serve as the sink for both pipes if shutdown occurs with a still-connecting pipe in place. It is also possible there could be issues around flushing the messages, but as I could not directly think how to create such an issue I have not written any code with regards to that.
      
      The documentation has been updated to reflect the change, but please do check over the code and test and review.

      Implement ZMQ_TCP_ACCEPT_FILTER setsockopt() for listening TCP sockets. · acba6bdd
      Sergey KHripchenko authored
      Assign arbitrary number of filters that will be applied for each new TCP transport
      connection on a listening socket.
      If no filters applied, then TCP transport allows connections from any ip.
      If at least one filter is applied then new connection source ip should be matched.
      To clear all filters call zmq_setsockopt(socket, ZMQ_TCP_ACCEPT_FILTER, NULL, 0).
      Filter is a null-terminated string with ipv6 or ipv4 CIDR.
      
      For example:
      localhost
      127.0.0.1
      mail.ru/24
      ::1
      ::1/128
      3ffe:1::
      3ffe:1::/56
      
      Returns -1 if the filter couldn't be assigned(format error or ipv6 filter with ZMQ_IPV4ONLY set)
      
      P.S.
      The only thing that worries me is that I had to re-enable 'default assign by reference constructor/operator'
      for 'tcp_address_t' (and for my inherited class tcp_address_mask_t) to store it in std::vector in 'options_t'...

      Outstanding requests dropped when requester dies (issue 190) · d1373792
      Martin Sustrik authored
      So far the requests in req/rep pattern were delivered to and processed
      by worker even though the original requester was dead. Thus,
      the worker processing replies with noone to deliver results to.
      This optimisation drops requests in two situations:
      
      1. Queued inbound requests in XREP socket when peer disconnects.
      2. Queued outbound requests in XREQ when socket is closed.

      Introduces bi-directional pipes · acf0b0e5
      Martin Sustrik authored
      So far, there was a pair of unidirectional pipes between a socket
      and a session (or an inproc peer). This resulted in complex
      problems with half-closed states and tracking which inpipe
      corresponds to which outpipe.
      
      This patch doesn't add any functionality in itself, but is
      essential for further work on features like subscription
      forwarding.

      ZMQ_MCAST_LOOP removed · b45b68ae
      Martin Sustrik authored
      Multicast loopback is not a real multicast, rather a kernel-space
      simulation. Moreover, it tends to be rather unreliable and lossy.
      Removing the option will force users to use transports better
      suited for the job, such as inproc or ipc.
