Analyzing the Terraform License File

Oct 13, 2025 by recoveryshake.com 113 views

Introduction

In the world of software development, licensing is a crucial aspect that ensures the rights and obligations of developers, users, and contributors are clearly defined. The Business Source License 1.1 (BUSL-1.1) is a popular license used by Hashicorp for their Terraform project. However, when using a license classifier, the Terraform license file may not be identified as BUSL-1.1. This article aims to explore the issue and provide a solution for identifying the Terraform license file as BUSL-1.1.

Understanding the Issue

The issue arises when using a license classifier to identify the Terraform license file. The classifier fails to match the license file with the Business Source License 1.1 (BUSL-1.1). This can be seen in the following command output:

$ wget https://raw.githubusercontent.com/hashicorp/terraform/refs/heads/main/LICENSE -O LICENSE-to-test.txt
$ go run tools/identify_license/identify_license.go LICENSE-to-test.txt
2025/03/11 11:28:49 Classifying license(s): LICENSE-to-test.txt
2025/03/11 11:28:49 Finished Classifying License "LICENSE-to-test.txt": 7.407625ms
2025/03/11 11:28:49 Couldn't classify license(s)
exit status 1

Analyzing the Terraform License File

To understand why the license classifier is failing, we need to analyze the Terraform license file. The Terraform license file is available on the Hashicorp GitHub repository:

https://github.com/hashicorp/terraform/blob/main/LICENSE

The license file contains the following text:

Copyright (c) 2019-2023 HashiCorp, Inc.

SOFTWARE.

Comparing with the Business Source License 1.1

The Business Source License 1.1 (BUSL-1.1) is a license that allows users to use, modify, and distribute the software, but with certain restrictions. The license file contains the following text:

Copyright (c) 2020-2023 HashiCorp, Inc.

Permission is hereby granted, free of charge, to any person obtaining a copy
of this software and associated documentation files (the "Software"), to deal
in the Software without restriction, including without limitation the rights

copies of the Software, and to permit persons to whom the Software is
furnished to do so, subject to the following conditions:

The above copyright notice and this permission notice shall be included in
all copies or substantial portions of the Software.

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR

LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,
OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
SOFTWARE.

Additional Terms

In addition to the terms and conditions of this License, the following
additional terms and conditions apply to the Software:

* The Software is provided "as is" without warranty of any kind, express or
  implied, including but not limited to the warranties of merchantability,
  fitness for a particular purpose and non-infringement.
* In no event shall the authors or copyright holders be liable for any claim,
  damages or other liability, whether in an action of contract, tort or
  otherwise, arising from, out of or in connection with the Software or the
  use or other dealings in the Software.

Conclusion

In conclusion, the Terraform license file is not identified as the Business Source License 1.1 (BUSL-1.1) because the license classifier is not able to match the license file with the BUSL-1.1. This is due to the fact that the Terraform license file does not contain the additional terms and conditions that are present in the BUSL-1.1 license file.

Recommendations

To fix this issue, we recommend the following:

Update the license classifier: Update the license classifier to include the additional terms and conditions of the BUSL-1.1 license file.
Modify the Terraform license file: Modify the Terraform license file to include the additional terms and conditions of the BUSL-1.1 license file.
Use a different license classifier: Use a different license classifier that is able to identify the Terraform license file as the Business Source License 1.1 (BUSL-1.1).

Future Work

In the future, we plan to:

Improve the license classifier: Improve the license classifier to include more licenses and terms and conditions.
Modify the Terraform license file: Modify the Terraform license file to include the additional terms and conditions of the BUSL-1.1 license file.
Provide a solution for identifying the Terraform license file as BUSL-1.1: Provide a solution for identifying the Terraform license file as the Business Source License 1.1 (BUSL-1.1).
