RTR_ListFiles returns empty "resources"

[TaihouKai]

I tried to get files with the following function:

def cmd_rtr(rtr_admin, session_id, base_cmd, cmd, timesleep, timemax):
    # Execute RTR command
    cloud_request_id = exec_cmd_rtr(rtr_admin, session_id, base_cmd, cmd)["cloud_request_id"]
    print(f"Command executed: {cloud_request_id}")

    # Wait for RTR command to finish
    res = None
    completed = False
    count = 0
    while (not completed):
        time.sleep(timesleep)
        res = check_cmd_rtr(rtr_admin, cloud_request_id)
        completed = res["cmd_completed"]
        if (count * timesleep > timemax):
            print(f"Timeout! Please try again.")
            sys.exit()

    # RTR command stdout
    res_out = res["cmd_status"]["body"]["resources"][0]

    return {"std_out": res_out["stdout"], "std_err": res_out["stderr"], "cloud_request_id": cloud_request_id}

And use RTR_ListFiles to list all files after get:

files = rtr.RTR_ListFiles(session_id=session_id)["body"]["resources"]

But, sometimes (not always) it returns:

{
  'status_code': 200, 
  'headers': {
    'Server': 'nginx', 
    'Date': 'Tue, 17 Jan 2023 02:14:39 GMT', 
    'Content-Type': 'application/json', 
    'Content-Length': '158', 
    'Connection': 'keep-alive', 
    'Content-Encoding': 'gzip', 
    'X-Cs-Region': 'us-1', 
    'X-Cs-Traceid': '01e03607-8ae2-4080-88a6-cc5e427abcc7', 
    'X-Ratelimit-Limit': '6000', 
    'X-Ratelimit-Remaining': '5988', 
    'Strict-Transport-Security': 'max-age=31536000; includeSubDomains'
  }, 
  'body': {
    'meta': {
      'query_time': 0.007406469, 
      'powered_by': 'empower-api', 
      'trace_id': '01e03607-8ae2-4080-88a6-cc5e427abcc7'
    }, 
  'resources': [], 
  'errors': []
  }
}

Is it because the file is not ready yet? I thought I've waited for the GET command to complete in cmd_rtr function.

If this is the case, how should I tell the program to wait until the file is ready, besides a loop check until it finds something?

Hi @TaihouKai -

Thanks for the question!

You're correct, this is most likely occurring because the file transfer has not yet completed. You're also on the correct path to address this. Similar to how you check for command execution with cloud_request_id using the RTR_CheckCommandStatus operation above, we can implement a loop check. (You could add a sleep timer for a few seconds, or minutes, depending on your scenario.)

Regarding the command execution loop check: You can check for the value of complete in the results returned from RTR_CheckCommandStatus, but it is safer to check the contents of stdout and stderr. While this happens rarely, when the result exceeds the available size for stdout, it is chunked across multiple pages (using the sequence_id value). When this occurs, the value of complete will be False.

Thank you so much for your answer!
