Plugins » Katello

In its current state, the enabled_repos_upload yum/dnf plugin imports the yum or dnf Python module and creates an associated object each time _replace_vars() is executed. This can lead to time consuming yum operations if there are a large number of enabled yum repositories.

Example
A server has 13 enabled yum repositories. With yum.YumBase() being executed each time _replace_vars() is called, this is the output from a simple yum check-update:

# time yum check-update
