# Development - Contributing

First, you might want to see the basic ways to [help FastAPI and get help](help-fastapi.md).

## Developing

If you already cloned the [fastapi repository](https://github.com/fastapi/fastapi) and you want to deep dive in the code, here are some guidelines to set up your environment.

### Install requirements

Create a virtual environment and install the required packages with [`uv`](https://github.com/astral-sh/uv):

export MINIO_SCANNER_SPEED=fastest

(minio server http://localhost:9000/tmp/xl/{1...10}/disk{0...1} 2>&1 >/tmp/decom.log) &
pid=$!

export MC_HOST_myminio="http://minioadmin:minioadmin@localhost:9000/"

./mc ready myminio

./mc admin user add myminio/ minio123 minio123
./mc admin user add myminio/ minio12345 minio12345

./mc admin policy create myminio/ rw ./docs/distributed/rw.json

    if x_token != fake_secret_token:
        raise HTTPException(status_code=400, detail="Invalid X-Token header")
    if item.id in fake_db:
        raise HTTPException(status_code=409, detail="Item already exists")
    fake_db[item.id] = item.model_dump()

        if (current != null && !value.equalsIgnoreCase(current)) {
            LOGGER.info(
                    "System property '" + Constants.MAVEN_LOGGER_DEFAULT_LOG_LEVEL + "' is already set to '" + current
                            + "' - ignoring system property and get log level from -X/-e/-q options, log level will be set to "
                            + value);
        }
    }

    @Override

  # Create the name if it does not exist
  echo "Checking policy: $NAME (in /config/$FILENAME.json)"
  if ! checkPolicyExists $NAME ; then
    echo "Creating policy '$NAME'"
  else
    echo "Policy '$NAME' already exists."
  fi
  ${MC} admin policy create myminio $NAME /config/$FILENAME.json

}
