CS131 Project Sample Grading Script

• Maintained and updated on CS131 TA Organization Reporitory since Winter 2020.
• This is not really a grading script because you didn't see any grading
• The evaluation giving you True / False something is somewhat partial credits for each task
• This is the simplest version of the core part of the grading script, but it doesn't contain any real test case
• You may regard it as a super client (who has the power of starting a server) as well.

Background

• This is for UCLA CS131 (Programming Languages) Project (instructor: Prof. Paul Eggert)
• This project is on Python, specifically aiming at the use of asyncio and aiohttp
• To complete the project a Google Map API Key is needed, I tried, in order to get rid of the limit you need payment information attached.

Resource

• Thanks to previous-year TA, Wenhao's code
• Following discussion online, to kill the process occupying port 8000 we could run:

  lsof -ti:8000 | xargs kill

• To run a script in the background I used nohup
• To execute command line within Python:

  import os
  os.system('sox input.wav -b 24 output.aiff rate -v -L -b 90 48k')

• under hint code repo I put my hint code for you to get started with this project there.

Usage

• put your server.py and all other needed .py files under the sample_submission folder
• modify the port number in client_basic.py (or keep them the same if you run on local machine --- the easiest way to test your code is to change your port number to around 800X and then test them on your local machine)
• could run single evaluation by

  python client_basic.py

• I think it should work for mac and linux, probably won't work on Windows
• Probably a little bit adaptation is needed, probably the version matters
• Probably some mistake in this readme... I was too tired when I wrote this
• Once it works, feel free to add your own test cases in client_basic.SuperClient.test; it's easy isn't it?

About organizing log files

You might want to have a look at os.mkdir and os.path.exists

What kind of submission is safe?

If you unzip your files into the sample_submission folder, with no extra effort required (e.g. don't need to create an empty folder manually, etc.), we can always make client_basic run (I mean if you occupy others' port then it is not guaranteed to work).
