22 # Mnemonic: run_call_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 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 # The call test drives three RMr based processes:
30 # caller which invokes rmr_mt_call() to send n messages
32 # receiver which executes rmr_rts_msg() on each received
33 # message with type == 5.
35 # sender which sends n "pings" to the caller process
37 # The script assumes that all three proessess are running on the same
38 # host/container such that setting up the route table with localhost:port
41 # The number of message, and the delay between each message may be given
42 # on the command line. The number of threads may also be given. The
43 # number of messages defines the number _each_ caller will sent (5000
44 # messages and three threads == 15,000 total messages.
46 # Example command line:
47 # ksh ./run_call_test.ksh # default 10 messages at 1 msg/sec 3 threads
48 # ksh ./run_call_test.ksh -n 5000 -t 6 -d 400 # 5k messages, 6 threads, delay 400 mus
51 # Author: E. Scott Daniels
52 # ---------------------------------------------------------------------------------
55 # The sender and receiver are run asynch. Their exit statuses are captured in a
56 # file in order for the 'main' to pick them up easily.
59 ./caller $nmsg $delay $nthreads
60 echo $? >/tmp/PID$$.src # must communicate state back via file b/c asynch
63 # start receiver listening for nmsgs from each thread
65 ./mt_receiver $(( nmsg * nthreads )) # we'll test with the RMr multi threaded receive function
66 echo $? >/tmp/PID$$.rrc
69 # This will send 100 messages to the caller process. This is a test to verify that
70 # threaded calling is not affected by normal messages and that normal messages can
71 # be received concurrently.
74 RMR_RTG_SVC=9999 ./sender 100 100 4 3333 >/dev/NULL 2>&1 # send pings
78 # Generate a route table that is tailored to our needs of sender sending messages to
79 # the caller, and caller sending mtype == 5 to the receiver.

85 # receiver, and all others go to the caller.
