What was the end-user problem that led to this PR?
The problem will occur once 2.0 is released -- there are many gems that declare a
s.dependency "bundler", "~> 1.x"
dependency on bundler. This would essentially make them inoperable with Bundler 2. We want to make adopting 2.0 as pain-free as possible, so hard conflicts are a no-go.Was was your diagnosis of the problem?
My diagnosis was that we need a way to allow conflicts on the bundler dependency once 2.0 comes out, so people can use 2.0.
What is your fix for the problem, implemented in this PR?
My fix introduces a feature flag for allowing these conflicts (enabled on 2.0), which when enabled will ignore bundler dependencies during resolution, and warn in the installer when a conflict would've occurred.
Why did you choose this fix out of the possible options?
I chose this fix because it has the minimal performance penalty with the feature flag enabled. This is mostly a port of #3871 to master.
