This ticket was prompted by this discussion on how IABot is unable to process articles above a certain (relatively low) size limit. Per Harej, it is not possible to increase the size limit without making this transition.

Code moved over to new VM; new web server needs to be set up and then redirect flask app needs to be made.

The new web server has been set up and https://iabot.wmcloud.org now loads, but:

• New OAuth grants need to be obtained for the new domain
• nginx needs to be configured to use more threads
• All requests need to be HTTP/2

This should be a usable app.py file for a Flask app that forwards traffic from iabot.toolforge.org to iabot.wmcloud.org:

from flask import Flask, redirect, request, url_for

app = Flask(__name__)

BASE_URL = 'https://iabot.wmcloud.org'

@app.route('/', defaults={'path': ''})
@app.route('/<path:path>')
def redirect_to_new_domain(path):
    new_url = f"{BASE_URL}/{path}"
    if request.args:
        new_url = f"{new_url}?{request.query_string.decode('utf-8')}"

    return redirect(new_url, code=301)


if __name__ == '__main__':
    app.run(debug=True)
