Upgrading to latest version of cwl-runner breaks command line inputs

[prismofeverything]

The previous version of cwl-runner I could do this:

cwl-runner cat.cwl --input README.md 

using the following workflow (performs a simple cat):

#!/usr/bin/env cwl-runner
cwlVersion: "cwl:draft-3"
class: CommandLineTool
description: "This tool is developed for SMC-RNA Challenge for detecting gene fusions (STAR fusion)"
inputs:
  #Give it a list of input files
  - id: input
    type: File
    inputBinding:
      position: 0 
outputs:
  - id: output
    type: File
    outputBinding:
      glob: test.txt
stdout: test.txt
baseCommand: [cat]

and I would get a result:

Final process status is success
{
    "output": {
        "size": 68, 
        "path": "/Users/spanglry/Code/importers/test.txt", 
        "checksum": "sha1$3f9848f75373e501d9832e9d47899b6ee3cfa780", 
        "class": "File"
    }
}

And the contents of README.md would be present in the output file test.txt.

Today I upgraded to the latest cwl-runner and the exact same process now fails!

Any idea what happened?

Hello @prismofeverything, thank you for your report.

Do you know which version of cwltool worked previously?

[prismofeverything]

This was the one:

/usr/local/bin/cwl-runner 1.0.20160310140736

[mr-c]

Then 021d3fd is the commit that worked; I'm looking into it now.

Oh, git bisect you are efficient and cruel: a3d24f8 is the first bad commit

commit a3d24f8da648befae983fe9f1b995713fdfcb28f
Author: Michael R. Crusoe <crusoe@ucdavis.edu>
Date:   Tue Mar 29 02:41:31 2016 -0700

    add type hints

Fixed in a85f8fd including a test using your sample code. Thank you for the test case!

Sorry for the bother.

Not at all, thanks for your speedy response!
