tracebin

Tracebin is a small flask application to receive Python tracebacks formatted with offlinetb. Simply POST the resulting JSON to the root url, and the app sends back the resulting uuid:

POST / HTTP/1.0
...

<<traceback data here>>

Returns:

HTTP/1.0 200 OK
Content-type: application/json
Content-Length: 107
...

{
    "id": "d9c7d8c5974911e189b7c82a1414d2bb",
    "url": "http://yoursever.com/d9c7d8c5974911e189b7c82a1414d2bb"
}

Subsequently, when you try to browse the resulting URL with a web browser, you'll be able to interactively explore the traceback and its frames.

This is particularly useful when deploying in-house solutions which occasionally fail and would like to report the failure details to a centralized location. This small utility enables you to just save the traceback URL and link to it from anywhere you want.

Example Code to Distill and Send Tracebacks

Below is a quick example of how you might use tracebin to save tracebacks:

import json
import urllib2
import offlinetb

try:
   some_function_that_might_raise_exceptions()
except Exception:
   response = urllib2.urlopen("http://your.tracebin.server/", json.dumps(offlinetb.distill()))
   traceback_url = json.loads(response.read())['url']

Installation

1. Clone the repository to anywhere you want (say /opt/tracebin/ on your server)

2. (optional) Create a Python virtualenv to run your application: virtualenv /opt/tracebin/env

3. Install requirements:

   /opt/tracebin/env/bin/pip install -r /opt/tracebin/env/src/pip_requirements.txt
   

4. To run the server as scgi, just run:

   /opt/tracebin/env/bin/python /opt/tracebin/src/app.py scgi -d /your/data/dir -s /path/to/socket/file
   

5. If you'd like your app to be installed on some URL path other than '/', use the '-r' flag to specify a url prefix
