Foreman Plugin Registry Loading

Observations

One

(Some/all?) plugins call Foreman::Plugin.register in a reloader.to_prepare callback which could imply a few things:

  • this needs to happen on app startup
  • this needs to happen on code reload
  • this involves application code

Two

Plugin registration is not consistent across plugins. Katello calls Foreman::Plugin.register via a required file which won't be executed again on reload!. REX and Foreman Tasks do invoke register on dev code reload and that's why reload! is broken.

Testing PRs in a production environment

Two options

  1. Add the github or gitlab repo as a remote and cherry-pick the PR on top. Good for large PRs with multiple commits that you may wish to apply independently or omit completely.
  2. Use curl to download the patch file from the PR. Good for small PRs!

Steps

Find the katello source code location and cd into it:
