bitbucket-toolkit

This is the toolkit for testing the performance of Bitbucket add-ons related to pull requests and post-receive hooks such as Snake CI.

Requirements

• task — alternative tool for make
• stacket — terminal cli for creating projects/repositories, installing add-ons

Features

Creating any number of:

• open pull-requests
• merged pull-requests (opening and merging them automatically)
• projects
• repositories

Installation

1. Install git-brancher:

$ cd git-brancher
$ go get -v 
$ go install

2. Build & Install the add-on into your running dev Bitbucket instance

cd addon
task atlas:install

Usage examples

• Creating 30000 projects with 5 repositories in each project:

  http -a admin:admin GET 'https://bitbucket.local/rest/toolz/1.0/repositories?prefix=y&projects=30000&repositories=5'
  

• Creating 100000 open & 100000 closed pull requests

  cd ./addon
  ./taskutils/pull-request snake-ci.yaml 10000 10000
  

  As result, it will produce 300000 branches and 300000 commits and will merge Pull Requests in parallel mode (16 threads).

  Why we create 2 brancher for merging PRs? Because we can't merge into master concurrently, it will produce mid-merge states and PullRequest resource will be out of date after any merge, so it's much safer and convienient to have two special branches for merging.

How does it work

The add-on exposes REST API for creating projects & repositories with the specified prefix using ProjectService & RepositoryService components.

The add-on registers post-receive hook that analyzes received changeset and creates PR for each branch that starts with pr-open- or pr-merge-. If branch starts with pr-merge-, the PR will be merged into x-pr-merge- branch with the same suffix as pr-merge has.

git-brancher is a tool written in Go that creates Git branches & Git commits into in-memory repository and pushes it into remote Bitbucket repository.

Tips

Start Bitbucket server in Docker container

docker run \
  --detach \
  --name "6.10.0.bitbucket" \
  -p 7990:7990 \
  -p 7999:7999 \
  -e SERVER_PROXY_NAME=bitbucket.local \
  -e SERVER_PROXY_PORT=443 \
  -e SERVER_SECURE=true \
  -e ELASTICSEARCH_ENABLED=false \
  -v $(readlink -f docker)/6.10.0:/var/atlassian/application-data/bitbucket \
  atlassian/bitbucket-server:6.10.0
