22 # Mnemonic: run_app_test.ksh
23 # Abstract: This is a simple script to set up and run the basic send/receive
24 # processes for some library validation on top of nano/nng.
25 # It should be possible to clone the repo, switch to this directory
26 # and execute 'ksh run -B' which will build RMr, make the sender and
27 # recevier then run the basic test.
29 # Example command line:
30 # ksh ./run_app_test.ksh # default 20 messages at 2 msg/sec
31 # ksh ./run_app_test.ksh -N # default but with nanomsg lib
32 # ksh ./run_app_test.ksh -d 100 -n 10000 # send 10k messages with 100ms delay between
35 # Author: E. Scott Daniels
36 # ---------------------------------------------------------------------------------
39 # The sender and receiver are run asynch. Their exit statuses are captured in a
40 # file in order for the 'main' to pick them up easily.

67 # Drop a contrived route table in. This table should add a reference to our
68 # local IP to an entry to ensure that the route table collector code in RMr
69 # is removing 'hairpin' loops. If RMr isn't removing the references to our
70 # hostname and IP address when it builds the endpoint lists, the sender will
71 # send messages to itself some of the time, causing the receiver to come up
72 # short when comparing messages received with expected count and thus failing.
