When an RPM diff was performed between two docker objects, we
previously only store the name, version, and epoch of the RPM for
comparision. It turns out versioning information is also done in
the release portion as well.
This addresses https://github.com/projectatomic/atomic/issues/315
Under the condition that you diff two images and one or both
of the images are not RPM based, no cleanup of the mounts and
dm devices was done. This was reported via BZ #1285006.
We now handle the exit and cleanup differently which counts
for this condition.
Also added a try/except for catching control-c, where if found
it will clean up the mounts and dm devices.
Set a pattern where if an atomic subfunction
is lengthy, then we can break that out into its own class.
This reduces the overall size of the Atomic class and allows
new development and debug to be cleaner.
Instead of using the func function of argparser, we pass
the Class and Function that should be run as variables. For
example, the Atomic verify subfunction would now be:
_class=Atomic.Atomic, func='verify'
The defined class is instantiated after parseargs is run. We
then perform the set_args and call the function.
Allow users to diff between two docker images|container. There
are two types of diffs that can be run -- a file diff or an
RPM diff. The file diff is always the default. The RPM diff
can be added with -r. The file diff can be excluded with -n.
