How can we make multi-series charms single series? #95

Open mbruzek opened 7 years ago

mbruzek commented 7 years ago

@kwmonroe and I are trying to help our IBM partners resolve an issue. They have a multi-series charm named 'ibm-im'. They are trying to add some support for 'xenial' only and are not able to push a single series over a multi-series charm. https://jujucharms.com/u/ibmcharmers/ibm-im/

Can you please tell us how to make a multi-series charm single series again?

We tried several different things, such as editing the metadata.yaml with the proper seris and tried to push a single series. Here is the output:

ubuntu@5e3e0fb7c2ac:~/charms/trusty/ibm-im$ charm push . cs:~ibmcharmers/trusty/ibm-im  
ERROR cannot post archive: charm name duplicates multi-series charm name cs:~ibmcharmers/ibm-im-7
...
ubuntu@5e3e0fb7c2ac:~/charms/xenial/ibm-im$ charm push . cs:~ibmcharmers/xenial/ibm-im
ERROR cannot post archive: charm name duplicates multi-series charm name cs:~ibmcharmers/ibm-im-8

Here is the listing of the charm revisions.

$ charm show cs:~ibmcharmers/ibm-im revision-info

  - cs:~ibmcharmers/trusty/ibm-im-2
  - cs:~ibmcharmers/trusty/ibm-im-1
  - cs:~ibmcharmers/trusty/ibm-im-0

We essentially want to reset this back to 6 and go from there.

This was by design, @urosj are we likely to support doing this?

We are not planning to allow this. Once multi-series, always multi-series. You can make another charm with a different name, or make the charm logic resilient to the different series.

I get hit by this from multiple angles and would emphasize that there are fundamental worries to this, perhaps with also some soft values to the project juju itself.

I've written on this in the discourse: https://discourse.juju.is/t/support-multiple-os-series-in-a-single-charm/3121/6
