[zeromq-dev] PGM 2.0.19rc4 updates require code changes in ZMQ2

Hello Steven,

0MQ pgm_sender has transport->can_recv_data set to false, so transport->pending_notify is not initialized.
Any workaround?

  Hi Hi,

    I noticed Malo recently updated to 2.0.18rc3 which missed the rate control precision update Martin worked on before.  I ran through all the unit and network tests and discovered a few major regressions in functionality for certain edge conditions. One of these was the TX thread needs to wake a waiting RX thread if it's timeout value is longer than the first SPM heartbeat interval (used for flushing stream ends).  I re-use the pending event FD that the RX thread currently uses to notify the application of receive-state generated events.

  For ZMQ this means pgm_sender.[ch]pp and pgm_socket.cpp need to be updated with the additional FD retrieved via pgm_transport_get_pending_fd().
