Output Filenames are URL Encoded

I am observing an issue where output filenames with special characters are URL encoded when copied from the tmp directory to the final output directory. For example, if a CommandLineTool writes a file whose name contains parenthesis, it will be written under the correct (non-encoded, i.e. “(parentheses).txt”) name in the tmp directory but this file will be relocated to the output directory under a URL encoded name, i.e. “%28parentheses%29.txt”

  • Under cwltool 3.0.2021031914372, this caused the runner to fail completely because it would search for the URL encoded filename in the tmp directory and fail to find it
  • Under cwltool 3.1.20210426140515, the runner is able to correctly identify the file in the tmp directory but relocates outputs under their URL encoded filenames


class: CommandLineTool
cwlVersion: v1.0

baseCommand: touch

        type: string
            position: 0
        type: File
            glob: $(inputs.inp)

{"inp": "(parentheses).txt"}

While this strikes me as a bug, I just thought I would check here first to make sure I’m not misusing the platform somehow. Thank you for your time and expertise!

Issue created. I’m going with my assumption that this is unintentional behavior.
