Chunks not cleaned when removing a file

[zedtux]

We are facing a database size increase in our MongoDB 5 server since we've upgraded some gems including this one from our Rails 6.1 application.

Basically, when deleting a model that has a Carrierwave mounter with the :grid_fs storage engine, it destroys the GridFs::File but not the associated GridFs::Chunk.

I can't find any test from this gem checking for the cleaning of the chunks since, I guess, it's up to the mongoid-grid_fs gem to take care of it.

Have anyone experienced this issue ?

Hi! To fix this issue and destroy associated chunks together with file i added monkey patch for delete method

module CarrierWave
  module Storage
    class GridFS
      class File
        def delete
          grid_file.destroy if grid_file
        end
      end
    end # GridFS
  end # Storage
end # CarrierWave

P.S. this patch also fixed for me issue with producing of orphan chunks.
