How to modify the code to adapt to the latest version of Zenoh?

[stevebobaaa]

The following code is from the old version of Zenoh, and some of the packages used in it are no longer usable. How can I modify it?

Thank you so much！

conf = zenoh.Config()
basekey = "/sdn/zone1"
zenoh.init_logger()
session = zenoh.open(conf)
zones = ["zone2","zone3"]

sub1 = session.subscribe("/sdn/host-pkt/**",topology_update,reliability=Reliability.Reliable, mode=SubMode.Push)

store = {}
sub = session.subscribe(basekey + "/hosts/**", listener, reliability=Reliability.Reliable, mode=SubMode.Push)
queryable = session.queryable(basekey + "/hosts/**",STORAGE, query_handler)
store_bs = {}
sub_bs = session.subscribe(basekey + "/BS/**", listener_bs, reliability=Reliability.Reliable, mode=SubMode.Push)

Hi @stevebobaaa,

Which version of Zenoh are you using?

In Zenoh website you can find a section with migration guides from older version of the APIs to new ones: https://zenoh.io/docs/migration

[stevebobaaa]

https://zenoh-python.readthedocs.io/en/0.5.0-b8/zenoh-net-api.html
I have found some interfaces used in the code in this link, such as SubMode. How can I convert them into ones that can be used in the current version?

[stevebobaaa]

Or can I use a Zenoh of 0.5.0-b8? How can I install it?

[gabrik]

We really discouraged using such an old version of Zenoh, I think porting the code is the better solution.

[stevebobaaa]

OK, of course, porting the code is the best way, but the https://zenoh.io/docs/migration/migrationguide-python-v0.5.x-v0.6.x/ link says that Zenoh net has been removed. Which APIs can be replaced in the new version of Zenoh? And the Discord in the link is no longer available. What should I do?
Thank you very much!

[gabrik]

Zenoh-Net has been integrated in the Zenoh API.
Thank you for poiting out that the discord link does not work, here the correct one: https://discord.gg/Z9f8fKydKK
We are going to update the one in the webpage
