New Streaming-parser proposal: traceroute-s

[Mabuchin]

Overview

Currently, traceroute does not support streaming IO parsing. Given that traceroute can sometimes take a long time to complete, it would be beneficial in many cases to receive data via a stream as it becomes available, rather than waiting for the entire command to finish.

Proposal

I propose implementing a new feature, traceroute-s, which would return data in a streaming format. This would allow for real-time processing of traceroute data as it's generated.

Response Format

The streaming parser would return data in the following JSON format:

{
  "type":                       "string",   # 'header', 'hop', 'error', 
  "destination_ip":             "string",
  "destination_name":           "string",
  "hops": [
    {
      "hop":                "integer",
      "probes": [
        {
          "annotation":     "string",
          "asn":            "integer",
          "ip":             "string",
          "name":           "string",
          "rtt":            "float"
        }
      ]
    }
  ],
  # below object only exists if using -qq or ignore_exceptions=True
  "_jc_meta": {
    "success":                  "boolean",  # false if error parsing
    "error":                    "string",   # exists if "success" is false
    "line":                     "string"    # exists if "success" is false
  }
}

Implementation Status

I have already implemented this feature in a fork of traceroute-s. If this proposal is accepted, I'm ready to submit it as a Pull Request.
