Setting up an Environment

This section was tested on macOS and Linux (Fedora 32, Ubuntu 20.04) - Your mileage may vary

Our Go release workflow holds the Go and Node.js versions we currently use under go-version and node-version compatibly. The Java workflows use Maven 3.8.1 (but any recent version of Maven should work).

  1. Install the required dependencies for your OS:
    1. Git
    2. GNU make (probably best to install from your OS package manager such as apt or brew)
    3. Docker
    4. Go
    5. Node.js & npm
    6. Maven to build and test Spark client codes.
    7. Optional - PostgreSQL 11 (useful for running and debugging locally)
  2. Install statik:

    go get github.com/rakyll/statik 
    

    Make sure (go env GOPATH)/bin is in your $PATH (or at least, that the statik binary is).

  3. Clone the repository from https://github.com/treeverse/lakeFS (gives you read-only access to the repository. To contribute, see the next section).
  4. Build the project:

    make build
    
  5. Make sure tests are passing:

    make test 
    

Before creating a pull request

  1. Review this document in full
  2. Make sure there’s an open issue on GitHub that this pull request addresses, and that it isn’t labeled x/wontfix
  3. Fork the lakeFS repository
  4. If you’re adding new functionality, create a new branch named feature/<DESCRIPTIVE NAME>
  5. If you’re fixing a bug, create a new branch named fix/<DESCRIPTIVE NAME>-<ISSUE NUMBER>

Creating a pull request

Once you’ve made the necessary changes to the code, make sure tests pass:

   make test 

Check linting rules are passing:

   make checks-validator

lakeFS uses go fmt as a style guide for Go code.

After submitting your pull request

After submitting your pull request, GitHub Actions will automatically run tests on your changes and make sure that your updated code builds and runs on Go 1.16.2.

Check back shortly after submitting your pull request to make sure that your code passes these checks. If any of the checks come back with a red X, then do your best to address the errors.
