DNF will become the default package manager in Fedora 22 and beyond. We will need to ship DNF plugins equivalent to our yum plugins today.
DNF’s plugin API looks relatively straightforward compared to yum’s.
It looks like plugins just need to be in the python path, install and examine ‘dnf-plugins-core’ for examples.
We should refactor code to core subscription-manager if it needs to be shared between the plugins.
We should take this opportunity to cleanup the plugin directory structure:
Yum plugins currently are bundled up with the base subscription-manager package. Should we bundle dnf up here as well? Or split them out into sub-packages and deal with the wrangling that will need to be done to get them into appropriate base installations? Easier to just bundle provided the files are not harmful, but probably more correct to create sub-packages. Alternatively we could modify the spec file to only bundle DNF for Fedora 22+, otherwise yum.
Address the dependency on yum in our spec file. Conditional on RHEL / Fedora version?
Our product-id.py yum plugin uses a posttrans hook, which looks like it maps to the DNF transaction() hook.
subscription_manager.productid.ProductManager will need to be updated to be less/not yum specific.
On the yum base object we make the following calls:
Our subscription-manager.py yum plugin uses a postconfig hook, which looks like it maps to the DNF config() hook.
This plugin does not appear to use many yum internals, it’s goal is just to trigger the generation of redhat.repo at the appropriate time.
