Hi,
I am doing some tests with the Python API for VPP and I've run into some
problems with asynchronous operations.
My current test script is loosely based on the examples from the wiki page - I
have included a snippet below:
####
from vpp_papi import VPP
vpp_json_dir = '/usr/share/vpp/api'
def papi_event_handler(msgname, result):
# Currently just printing content of messages
vpp = VPP(<list of files in above dir>
vpp.connect("test_papi", async=True)
vpp.status()
vpp.api.show_version() # Verifying that api files are loaded and working
vpp.register_event_callback(papi_event_handler)
vpp.api.want_stats(True, 1231) # This is where the issues start occurring
sleep(20)
vpp.api.want_stats(False, 1231)
vpp.disconnect()
####
Running the script returns an error with want_stats():
Traceback (most recent call last):
File "stats.py", line 48, in <module>
vpp.api.want_stats(True, 1231)
TypeError: __call__() takes exactly 1 argument (3 given)
Removing the arguments stops the error from showing, but also causes no stats
to be sent.
The api file, stats.api.json, lists the arguments as ("enable_disable", "pid"),
but it looks like the parser isn't expecting any arguments.
Am I using the API incorrectly, or is there a bug somewhere in the parser?
Best Regards,
Michael Pedersen
