Taxing Collaborative Software Engineering

Replication package for our work on "Taxing Collaborative Software Engineering"

Requirements

This replication package requires Python 3.10 or higher. Install the dependencies via:

python3 -m pip install -r requirements.txt

For a faster loading, we recommend to optionally install orjson via pip:

python3 -m pip install orjson

First, we collect all timelines from all pull requests at a GitHub instance. crawler.py requires an <api_token> for your GitHub instance and an <out_dir> where the results are stored into:

python3 crawl.py <api_token> <out_dir>

crawl.py also provides the following optional command line arguments:

--api_url for the GitHub instance URL (default: https://api.github.com)
--disable_cache for disable caching (for larger instances not recommended)
--num_workers for parallel processes (default: 1)
--organization for limiting to one organization (helpful for organizations hosted on github.com)

To list all options in detail, run:

python3 crawl.py --h

For this step, you will need:

The directory of the previously collected data; and,
A mapping of users and countries. This can be either a dict for a static mapping (does not capture changes in the users' location over time) or a dataframe for time-dependent mapping as data frame monthly sampled (captures changes in the users' location over time).

Run notebook.ipynb. Look out for the instructions as inline comments.
