Interceptors
============

Interceptors are a powerful mechanism that can monitor, rewrite, and retry calls. Here's a simple interceptor that logs the outgoing request and the incoming response.

```java
class LoggingInterceptor implements Interceptor {
  @Override public Response intercept(Interceptor.Chain chain) throws IOException {
    Request request = chain.request();

    long t1 = System.nanoTime();

  are not allowed to login via FTP/SFTP ports, you must use S3 API port for if you are using
  rotating credentials.

- Access to bucket(s) and object(s) are governed via IAM policies associated with the incoming
  login credentials.

- Allows authentication and access for all
  - Built-in IDP users and their respective service accounts
  - LDAP/AD users and their respective service accounts
  - OpenID/OIDC service accounts

  optional string operation = 7;

  // UserInfo is information about the requesting user
  optional k8s.io.api.authentication.v1.UserInfo userInfo = 8;

  // Object is the object from the incoming request.
  // +optional
  optional k8s.io.apimachinery.pkg.runtime.RawExtension object = 9;

  // OldObject is the existing object. Only populated for DELETE and UPDATE requests.
  // +optional

  optional string operation = 7;

  // UserInfo is information about the requesting user
  optional k8s.io.api.authentication.v1.UserInfo userInfo = 8;

  // Object is the object from the incoming request.
  // +optional
  optional k8s.io.apimachinery.pkg.runtime.RawExtension object = 9;

  // OldObject is the existing object. Only populated for DELETE and UPDATE requests.
  // +optional

    echo "Detected MAC OSX launched script...."
    echo "Swapping to UI"
    addResidual "ui"
  }
}

# Processes incoming arguments and places them in appropriate global variables.  called by the run method.
process_args () {
  while [[ $# -gt 0 ]]; do
    case "$1" in
       -h|-help) usage; exit 1 ;;

Another big feature needed by APIs is data validation, making sure that the data is valid, given certain parameters. For example, that some field is an `int`, and not some random string. This is especially useful for incoming data.

Without a data validation system, you would have to do all the checks by hand, in code.

These features are what Marshmallow was built to provide. It is a great library, and I have used it a lot before.

- kubeadm now includes a new EXPERIMENTAL `--rootfs`, which (if specified) causes kubeadm to chroot before performing any file operations.  This is expected to be useful when setting up kubernetes on a different filesystem, such as invoking kubeadm from docker. ([#54935](https://github.com/kubernetes/kubernetes/pull/54935), [@anguslees](https://github.com/anguslees))

// ----------
// Supports following actions:
// - restart (restarts all the MinIO instances in a setup)
// - stop (stops all the MinIO instances in a setup)
// - freeze (freezes all incoming S3 API calls)
// - unfreeze (unfreezes previously frozen S3 API calls)
func (a adminAPIHandlers) ServiceHandler(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()

	vars := mux.Vars(r)

So we have a dedicated thread for every socket that just reads frames and dispatches them.
