UNIT3D Open Source: How to Share Your Source Code

1. Introduction

As part of complying with the GNU Affero General Public License (AGPL), sites that modify and distribute UNIT3D are required to share their source code. This guide provides an easy process for creating a sanitized tarball of your modified source code and encourages you to create and update an "Open Source" page on your site to make this code available.

2. Setting Up Tarball Creation

2.1 Exclude Sensitive Files

To create a tarball that includes only the modified source code and excludes sensitive files like configuration data, you can take advantage of the existing .gitignore file in your UNIT3D deployment. Here’s how:

1. Reference .gitignore for Exclusions:

   If your production environment has the original .gitignore file that already lists the files and directories you don’t want to include in version control, you can use it to exclude those same items from your tarball:

   ln -s /var/www/html/.gitignore /var/www/html/.tarball_exclude

2. Additional Exclusions (if needed):

   If additional exclusions are needed, or if you've removed the git environment from your production environment, you should manually add the exclusions to the .tarball_exclude file:

   nano /var/www/html/.tarball_exclude

   Add the following to the file:

   .env
   node_modules
   storage
   vendor
   public
   *.gz
   *.lock
   UNIT3D-Announce
   laravel-echo-server.json
   config
   .DS_Store
   .idea
   .vscode
   nbproject
   .phpunit.cache
   .ftpconfig
   storage/backups
   storage/debugbar
   storage/gitupdate
   storage/*.key
   laravel-echo-server.lock
   .vagrant
   Homestead.json
   Homestead.yaml
   npm-debug.log
   _ide_helper.php
   supervisor.ini
   .phpunit.cache/
   .phpstan.cache/
   caddy
   frankenphp
   frankenphp-worker.php
   data
   config/caddy/autosave.json
   build
   bootstrap
   *.sql
   *.DS_Storecomposer.lock
   *.swp
   coverage.xml
   cghooks.lock
   *.pyc
   emojipy-*
   emojipy.egg-info/
   lib/js/tests.html
   lib/js/tests/npm-debug.log
   

2.2 Create the Tarball

1. Create a script to generate the tarball:

   nano /var/www/html/create_tarball.sh

2. Add the following content to the script:

   #!/bin/bash
   
   TARBALL_NAME="UNIT3D_Source_$(date +%Y%m%d_%H%M%S).tar.gz"
   TAR_EXCLUDES="--exclude-from=/var/www/html/.tarball_exclude"
   
   tar $TAR_EXCLUDES -czf /var/www/html/public/$TARBALL_NAME -C /var/www html
   
   # Create a symlink to the latest tarball
   ln -sf "/var/www/html/public/$TARBALL_NAME" "/var/www/html/public/UNIT3D_Source_LATEST.tar.gz"

3. Make the script executable:

   chmod +x /var/www/html/create_tarball.sh

4. Run the script manually whenever you update your site:

   /var/www/html/create_tarball.sh

3. Creating and Updating the Open Source Page

1. Create an Open Source page:

   Go to your site's /dashboard/pages section and create a new page called "Open Source."

2. Add the following Markdown content to the page:

   ## Open Source
   
   We comply with the UNIT3D's GNU Affero General Public License (AGPL) by sharing our modified source code. You can download the latest version of our source code below.
   
   - **[Download Latest Source Code](/UNIT3D_Source_LATEST.tar.gz)**
   
   ### License Information
   
   Our site runs on a modified version of [UNIT3D](https://github.com/HDInnovations/UNIT3D-Community-Edition). For more details on the license, visit the [GNU AGPL License](https://github.com/HDInnovations/UNIT3D-Community-Edition/blob/master/LICENSE).

3. Manually update this page whenever you update your site:

   After running the tarball creation script, update the page content if necessary to reflect any changes or additional notes about the modifications made.

4. Encouraging Compliance and Contributions

By publicly sharing your modified source code, you not only comply with the AGPL but also contribute to the open-source community. We encourage sites to contribute their changes back to the upstream repository by submitting pull requests, which helps improve UNIT3D for everyone.
