* YUM4/DNF compatibility via yum action plugin
DNF does not natively support allow_downgrade as an option, instead
that is always the default (not configurable by the administrator)
so it had to be implemented
- Fixed group actions in check mode to report correct changed state
- Better error handling for depsolve and transaction errors in DNF
- Fixed group action idempotent transactions
- Add use_backend to yum module/action plugin
- Fix dnf handling of autoremove (didn't used to work nor had a
default value specified, now does work and matches default
behavior of yum)
- Enable installroot tests for yum4(dnf) integration testing, dnf
backend now supports that
- Switch from zip to bc for certain package install/remove test
cases in yum integration tests. The dnf depsolver downgrades
python when you uninstall zip which alters the test environment
and we have no control over that.
- Add changelog fragment
- Return a pkg_mgr fact if it was not previously set.
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
* Rebalance Windows tests with another group.
* added integration tests for yum repository
* fixed escaped single quote
* extended yum_repository tests to include fedora
* removed unused variable file
* added check for return values
* replaced escaped double quotes with single quotes, switched to lookup for reading repofile
