(snap) jhack reads juju status as empty #30

I used pdb.set_trace() here to check the values of: (by following this method)
juju_status(json=True) was {}
jhack.helpers.juju_version() was '3.0.0'
jhack.helpers.juju_models() was ''

In my local environment:
juju version was 2.9.37-ubuntu-amd64
Copy-pasting code from tail_charms.py into a python3 interpreter gave me:
raw was '2.9.37-ubuntu-amd64'
raw.split("-")[0] was '2.9.37'

I did run this command: sudo snap connect jhack:dot-local-share-juju snapd

I also tried refreshing the snap from latest/stable: 0.3.2 2022-11-02 (120) to latest/beta: 0.3.2 2022-11-22 (124) and latest/edge: 0.3.2 2022-11-24 (126) with the same issue.

# something along the lines of
juju add-model foo

The text was updated successfully, but these errors were encountered:

Was able to replicate the issue when moving these commands from cloud-init to running with sudo as ubuntu user:

snap install juju --classic --channel=2.9/stable
snap install jhack
snap connect jhack:dot-local-share-juju snapd

On the same environment, installing via pip works so it appears to be snap related

Hi Carl, thanks for the report. I suspect it has something to do with some juju-envvars being unset in the python subprocess.
I normally don't develop in VMs so I'm not that familiar with the process.
If you run juju status from the console, does it show what's expected?
Could you pastebin me the output of listenv?
I see that the Popen I use already passes down the environment to the juju status process, but the question is if the snapped jhack has it in the first place.

carlcsaposs-canonical · 2023-01-03T13:49:51Z

juju status shows what's expected:

Model  Controller  Cloud/Region        Version  SLA          Timestamp
foo    micro       microk8s/localhost  2.9.29   unsupported  13:46:27Z

Model "admin/foo" is empty.

What is listenv (i.e. how do I run that)?

Here's the output of `printenv`

yeah sorry, printenv is what I meant. And I think I need the env as available to the snap -- something like snap run --shell jhack and then printenv

does anything show up with LOGLEVEL=INFO jhack tail?

And if you try and run juju status from the snap (after snap run --shell jhack). Does it give some output?

juju status after snap run --shell jhack

snap run --shell jhack
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

ubuntu@dev-env-jhack-snap:/home/ubuntu$ juju status
Model  Controller  Cloud/Region        Version  SLA          Timestamp
foo    micro       microk8s/localhost  2.9.29   unsupported  13:18:15Z

Model "admin/foo" is empty.

PietroPasotti · 2023-01-05T15:04:12Z

does it only happen when there are no applications (the status you posted shows an empty model), or also after you've deployed something? Maybe something changed in the juju status output. Can you share the output of
ubuntu@dev-env-jhack-snap:/home/ubuntu$ juju status --format=json?

carlcsaposs-canonical · 2023-01-05T15:14:38Z

It also happens after I deploy something

and inside of the snap shell

juju status --format=json
{}
ERROR juju client with major version 3 used with a controller having major version 2 not supported
update your juju client to match the version running on the controller

Juju version inside of the snap shell: 3.0.0-genericlinux-amd64
Juju version outside of the snap: 2.9.37-ubuntu-amd64

juju status without --format=json inside the snap shell works as expected

The juju agent version is 2.9.29

PietroPasotti · 2023-01-05T15:24:29Z

uh that's surprising. juju status works, but with --format=json gives {}?
