Puppet::Util::Platform.windows? vs Puppet.features.microsoft_windows?

So we have 2 mechanisms that we use to check whether or not we're on Windows.

In this particular instance, I think we'd prefer to use Puppet::Util::Platform.windows? as I wouldn't expect any cross-platform stubbing to occur in tests.

Fun times with Bundler + AppVeyor!

While documenting Bundler behavior to make the chart at https://gist.github.com/Iristyle/8a2214a6dd5aa709ba2a1abd32b4eacd, an interesting scenario was uncovered.

The following diff is a result of running the same code a day apart in AppVeyor. All dependencies downloaded / installed are exactly the same, except:

Demonstrate how to use Git to create a new repo with specific files from a current repo

I tried to initially do this using the perl based cj-git-filter-branch tool from https://github.com/pflanze/chj-bin (which required ensuring Perl was viable and a few CPAN packages were installed) with a CLI invocation like:

~/source/chj/chj-bin/cj-git-filter-branch --remove-all-but-those-in ../keepers.txt -f

And a keepers.txt like:

acceptance/tests/resource/scheduled_task/should_create.rb
