The notification handling in ynl is currently very simple, using sleep()
to wait a period of time and then handling all the buffered messages in
a single batch.
This patch changes the notification handling so that messages are
processed as they are received. This makes it possible to use ynl as a
library that supplies notifications in a timely manner.
- Change check_ntf() to be a generator that yields 1 notification at a
time and blocks until a notification is available.
- Use the --sleep parameter to set an alarm and exit when it fires.
This means that the CLI has the same interface, but notifications get
printed as they are received:
./tools/net/ynl/cli.py --spec <SPEC> --subscribe <TOPIC> [ --sleep <SECS> ]
Here is an example python snippet that shows how to use ynl as a library
for receiving notifications:
ynl = YnlFamily(f"{dir}/rt_route.yaml")
ynl.ntf_subscribe('rtnlgrp-ipv4-route')
for event in ynl.check_ntf():
handle(event)
