spdx-online-tools

Source for the website providing online SPDX tools. The tool provides an easy all-in-one website to upload and parse SPDX documents for validation, comparison and conversion and search SPDX license list. Here you can find more about the working of the tool.

Features

• Upload and parse SPDX Documents
• Validate SPDX Documents
• Compare Multiple SPDX Rdf Files
• Convert one SPDX format to another
• Compare License text to the SPDX listed Licenses

Requirements (Linux/Debian/Ubuntu)

Either the Sun/Oracle JDK/JRE Variant or OpenJDK. Python 3.7+.

Debian/Ubuntu users will have to install g++ and python-dev first:

sudo apt-get install g++ python-dev

Requirements (Windows)

Windows users need a Python installation and C++ compiler:

• Install Python 3.7 version, e.g., Anaconda is a good choice for users not yet familiar with the language
• Install a Windows C++ Compiler

Installation

1. Clone or download the repository.

2. Create a new virtual environment for the project.

   python3 -m venv ./venv
   source venv/bin/activate

   On Windows:

   py -m venv venv
   venv\Scripts\activate
   

3. Install the required python libraries given in the requirements.txt file.

   cd spdx-online-tools
   pip install -r requirements.txt

4. Run Django migrate.

   python src/manage.py migrate

5. (Optional) If you want use license-xml-editor with licenses/exceptions from spdx license list, download the license name database.

   python src/populate.py

6. (Optional) If you want to use the license submittal feature or check license feature, follow the below step(s):

   • Install redis server on your local machine.

     For linux users

     • Use the command sudo apt-get install redis-server to install the redis server.

     For Mac users

     • Install the redis by running the command

       brew install redis.

     • If you want to run redis whenever your computer starts then run

       ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents.

     • To run the redis server use

       launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist.

     • To test if the redis is working run the command redis-cli ping. If it returns Pong then you are good to go.

     For Windows users

     • Download the redis server from here and install it.

   • Make sure redis server is running and keep it running until you are done using the license submittal or check license feature.

     The redis is used to store the license text of license present on the SPDX license list. For the very first time it may take a while to build the license on the redis server.

     SPDX License Matcher matches the license text input by the user(via license submittal form) against the data present on the redis to find for duplicate and near matches.

7. Start the application.

   python src/manage.py runserver

8. Open localhost:8000/ in the browser.

9. Register and login to use the tools.

How to Run Tests

python src/manage.py test

Running with Docker

You need to have docker desktop installed on your machine for the container environment.

Prior to starting the docker image, you will need to create a file to set the environment variables described below.

Create a file ".env" with the following content:

DIFF_REPO_GIT_TOKEN=XXXX
DIFF_REPO_WITH_OWNER=XXXX
ONLINE_TOOL_GITHUB_KEY=XXXX
ONLINE_TOOL_GITHUB_SECRET=XXXX

You can bring up the Docker image with the following docker-compose command:

docker-compose -f docker-compose.dev.yml up --build

For the production environment, see the README-PRODUCTION.md file.

GitHub Developer Sensitive Data

The src/src/settings.py file uses sensitive data to work with the GitHub API. For that reason, sensitive data is maintained as environment variables. Due to that lack of data, some features of SPDX Online Tools and its API won't be able to run as they require the user credentials in order to access the GitHub API. So, the user is supposed to either maintain a .env file in the src/src/ folder or create environment variables in their os with their credentials in order to ensure proper functioning of the tool.

The src/src/secret.py file contains the following lines along with some methods required to run the tests properly. These include:

def getGithubKey():
    return os.environ.get(key="ONLINE_TOOL_GITHUB_KEY")

def getGithubSecret():
    return os.environ.get(key="ONLINE_TOOL_GITHUB_SECRET")

def getSecretKey():
    return os.environ.get(key="DJANGO_SECRET_KEY")

def getOauthToolKitAppID():
    return os.environ.get(key="OAUTH_APP_ID")

def getOauthToolKitAppSecret():
    return os.environ.get(key="OAUTH_APP_SECRET")
	
# The methods getDiffRepoGitToken and getDiffRepoWithOwner are used to configure the repository used for storing license diffs created during the license submittal process
# The DIFF_REPO_GIT_TOKEN is a personal access token created in Github with access to the repo DIFF_REPO_WITH_OWNER
    
def getDiffRepoGitToken():
    return os.environ.get(key="DIFF_REPO_GIT_TOKEN")
    
def getDiffRepoWithOwner():
    return os.environ.get(key="DIFF_REPO_WITH_OWNER", default="spdx/licenseRequestImages")

where:

• ONLINE_TOOL_GITHUB_KEY is the Client ID for the Github Oauth Apps (To create your Oauth application see this)
• ONLINE_TOOL_GITHUB_SECRET is the Client secret for the Github Oauth Apps
• DJANGO_SECRET_KEY is the Django secret
• OAUTH_APP_ID is the client ID of the django oauth toolkit app (To create your application see this)
• OAUTH_APP_SECRET is the client secret of the django oauth toolkit app (To create your application see this)
• DIFF_REPO_GIT_TOKEN is the Github user's Personal Access Token which has write access to DIFF_REPO_WITH_OWNER (Follow this to create your Github Personal access token with full repo and user scope access)
• DIFF_REPO_WITH_OWNER is the repo where images related to license submittable process are uploaded

Note: While setting up the GitHub OAuth App, set the Homepage URL to http://localhost:8000/ and the Authorization callback URL to http://localhost:8000/oauth/complete/github

How to Use API

Here is the exhaustive list of request and response fields of different api tools.

1. Start the server.

   python src/manage.py runserver

2. Send the request to the url with the form input values accordingly. Curl examples are given below.

3. For validation tool, send the request to /api/validate/.

   curl -X POST -u <admin>:<password> -F "file=@<fileInput>" -H "Accept: application/json" http://localhost:8000/api/validate/ | json_pp

4. For compare tool, send the request to /api/compare/.

   curl -X POST -u <admin>:<password> -F "file1=@<fileInput1>" -F "file2=<fileInput2>" -F "rfilename=<resultFileName>" -H "Accept: application/json" http://localhost:8000/api/compare/ | json_pp

5. For convert tool, send the request to /api/convert/.

   curl -X POST -u <admin>:<password> -F "file=@<fileInput>" -F "cfilename=<resultFileNameWithExtension>" -F "from_format=<convertFrom>" -F "to_format=<convertTo>" -H "Accept: application/json" http://localhost:8000/api/convert/ | json_pp

6. For license check tool, send the request to /api/check_license/.

   curl -X POST -u <admin>:<password> -F "file=@<fileInput>" -H "Accept: application/json" http://localhost:8000/api/check_license/ | json_pp

7. For the license submittal API, first create a django oauth toolkit application and follow the steps given below:

   Django Oauth Toolkit App

   • Go to admin page and login(if you don't have an admin account then create one using python src/manage.py createsuperuser).

   • Create a new application by going to the Applications section.

   • Copy the client id and client secret of the app and paste it in src/src/secret.py file under getOauthToolKitAppID and secret and fill the other details of the app as follows:

     • User: <admin you created>
     • client type: confidential
     • authorization grant type: resource owner password based

     and SAVE the app.

   Authorize oauth app with github to get code and send a request to the license submittal API

   • Visit https://github.com/login/oauth/authorize/?client_id=<github-client-id> it will then redirect you to a url, copy the code query string present in the url and send it via curl command if you want to use the API. if you want to run tests and test the API then paste the code in the src/src/secret.py file in the getAuthCode method.

     Note You can only use your code once. If you want to use the license submittal API again, you can generate a new code by following the above point. The code is valid for 10 minutes only.

   • Send the request to /api/submit-license/.

     curl -X POST http://localhost:8000/api/ submit_license/ -F 'fullname=<your-fullname>' -F 'shortIdentifier=<your-identifier>' -F 'licenseAuthorName=<license-author>' -F 'userEmail=<your-email>' -F 'text=<text>' -F 'osiApproved=<osi>' -F 'sourceUrl=<url>' -F 'code=<your-code-here>'
