    #replace(spec, checksum)  
  



  

    

Replace when the new checksum is from the same source. The primary purpose is registering checksums from gems where there are duplicates of the same gem (according to full_name) in the index.



In particular, this is when 2 gems have two similar platforms, e.g. “darwin20” and “darwin-20”, both of which resolve to darwin-20. In the ::Bundler::Index, the later gem replaces the former, so we do that here.



However, if the new checksum is from a different source, we register like normal. This ensures a mismatch error where there are multiple top level sources that contain the same gem with different checksums.
