#find_changed_paths(objects, merge_commit_diff_mode: nil) ⇒ Object

When finding changed paths and passing a sha for a merge commit we can specify how to diff the commit.

When diffing a merge commit and merge_commit_diff_mode is :all_parents file paths are only returned if changed in both parents (or all parents if diffing an octopus merge)

This means if we create a merge request that includes a merge commit of changes already existing in the target branch, we can omit those changes when looking up the changed paths.

e.g.

1. User branches from master to new branch named feature/foo_bar
2. User changes ./foo_bar.rb and commits change to feature/foo_bar
3. Another user merges a change to ./bar_baz.rb to master
4. User merges master into feature/foo_bar
5. User pushes to GitLab
6. GitLab checks which files have changed

case merge_commit_diff_mode when :all_parents

['foo_bar.rb']

when :include_merges

['foo_bar.rb', 'bar_baz.rb'],

else # defaults to :include_merges behavior

['foo_bar.rb', 'bar_baz.rb'],
