test failed, not sure why

[wgerlach]

Hi,
I am having problems passing test 107 with my implementation and do not understand what is wrong. The File object for file a should be what is expected, still cwltest complains. Any ideas?

Test [107/197] Test if a writable input directory is recursively copied and writable
Test 107 failed: /go/bin/awe-cwl-submitter-wrapper.sh --outdir=/tmp/tmp2k39bljr --quiet v1.0/recursive-input-directory.cwl v1.0/recursive-input-directory.yml

How about sorting the file and directory objects in the listing field for work_dir by their names?

I guess the conformance test 107 implicitly expects that they are sorted but such a behavior is not documented in the spec.
I am not sure it is mis-documented spec or it accidentally depends on a specific implementation such as cwltool.

However, IMO, the above output object should be accepted by cwltest (if the corresponding files and directories exist) because the spec of v1.1 says:

- Clarify that unspecified details related to execution are left open to the platform.

It is the same in v1.0 because v1.1 has no breaking changes from v1.0, I guess.

What do you think, @mr-c?

Maybe related: common-workflow-language/cwl-v1.2#233

[mr-c]

Hey @wgerlach and @tom-tan

CWL is built upon the POSIX standards. In https://www.commonwl.org/v1.0/CommandLineTool.html#CommandOutputBinding is

glob Find files relative to the output directory, using POSIX glob(3) pathname matching.

POSIX glob(3) states that the result mist be sorted according to the current locale.

I don't know of any locale that sorts the letters "a", "b", "c", "d", "e" in a different order.

[tom-tan]

@mr-c Thanks for the information and sorry for the misleading comment about related issue.

common-workflow-language/cwl-v1.2#233 is related but not the same issue.
This issue is about the sorting order of the objects in listing field, not the result of glob field.

As you mentioned, the result of glob should be sorted and it is described in the spec.
However there are no descriptions of the sorting order of listing field in directory object.

[wgerlach]

I figured the problem seems to be the cwltool!? Searching for the place in my code where the sort order gets messes up I noticed that it happens when my implementation invokes the cwltool to execute my CommandLineTool. Note that my implementation parses the original CommandLineTool and later, upon execution of a step, writes the CommandLineTool to disk. This CommandLineTool can be different from than the original compliance test, but should be equivalent.

Below are the tool, input and result of running cwltool. While the input is correctly sorted, the output is not. Of course, I could work around this by sorting the results again in my implementation, but it seems to me this should not have happened anyway. Any ideas?

I don't think it is an order issue, cwltest already does an order-independent comparison for listings:

https://github.com/common-workflow-language/cwltest/blob/master/cwltest/utils.py#L120

The comparison function is failing to find a, although it looks like it is there. There may be a very subtle difference between "actual" and "expected" that cwltest is not reporting in a useful way (and should probably ignore).

I think I found the problem in the compare_location function, but still do not fully understand this:

https://github.com/common-workflow-language/cwltest/blob/master/cwltest/utils.py#L79
The compare_location function compares this field, which is identical in actual and expected:

"location": "work_dir/a",

It seems that if they are identical it is expected that no "/" is supposed to be in the location string of the actual. I am not sure why this is required here, but that seems to be the problem.

The other problem is the missing error message. While an exception is thrown in compare_location, it is catched later and ignored, because the previous function compares all listing elements with each other to find matching pairs. I am not sure if there is a better solution to this. Would it be a safe assumption that the basename field always exists? If so, you could first search for matching basename, then compare the object and throw an exception if needed.
