[HTCondor-users] Problems using classad.quote in the Python bindings

[Gaetan Geffroy <gage@xxxxxxxxx>]

I am trying to submit jobs using Python, and there is some JSON in the arguments.

I am trying to use classad.quote to make these json strings understandable by Condor, but it does not look like it has the desired effect.

Here is what I am doing:

1. The command to send is stored in a list (ex: [‘ls’, ‘-alh’, ‘/root’])
   1. One of these arguments, in my case, is a dict transformed into a JSON using json.dumps
2. I separate the executable and the arguments:
   1. executable = command[0]
   2. command[6] = classad.quote(command[6])           # Here I try to sanitize my JSON
   3. arguments = ‘ ’.join(command[1:])
3. I create the submit object:

 

job = {

            "executable": executable,                   # Executable

            "transfer_executable": False,               # The executable is expected to be present in the docker image

            "arguments": arguments,                     # Arguments for the executable

            "universe": "docker",                       # Run job in Docker container

            "docker_image": docker_image,               # Docker image to be used

            "environment": self.convert_envvars(),      # Set the environment variables in container

            "should_transfer_files": "YES",             # Enable file transfer

            "transfer_input_files": inputs,             # Transfer files

            "output": self.stdout_filename,             # File where the stdout of the container will be written

            "error": self.stderr_filename,              # File where the stderr of the container will be written

        }

 

But then I get: ERROR:root:Condor Job Submission failed: Found illegal unescaped double-quote

 

After playing around a bit, it looks like the classad.quote function does not do what it is supposed to do:

Isn’t it supposed to escape all “ characters and surround everything with ‘ ’ ?

 

Thanks,
