This simple Python code force squashes, if you call this via a webhook automatically via gitlab, then "magic" all merges will squash

Gitlab Squasher

import os
import flask
import requests


BASE_URL = 'https://YOURGITLABURL/api/v4'
TOKEN = 'YOURADMINAPITOKEN'


app = flask.Flask(__name__)


@app.route('/', methods=['POST'])
def squash_remove_branch():
    data = flask.request.json
    if data['event_type'] != 'merge_request':
        return '', 200
    if data['object_attributes']['action'] != 'open':
        return '', 200

    project_id = data['project']['id']
    mr_id = data['object_attributes']['iid']
    url = '{0}/projects/{1}/merge_requests/{2}'.format(
        BASE_URL, project_id, mr_id)
    update_data = {'remove_source_branch': True, 'squash': True}

    resp = requests.put(
        url, data=update_data, headers={'private-token': TOKEN})
    if resp.status_code != 200:
        print('Error updating MR {0}: {1} {2}'.format(
            mr_id, resp.status_code, resp.text))

    return '', 200

    return 'OK', 200


if __name__ == '__main__':

Great stuff!

Great stuff!

Haha hey Ch00k! This is totally your baby, I hope you don't mind, I gist-ed this to share with a bunch of people on Gitlab.org complaining about the lack of this goddamn feature. Nice work on this btw. If I had the time/interest this would make its own great github repo with dockerfile and dockerhub for ease of use. :P No free time. Hope you're well man!
