With this patch, the external provisioner can remove the finalizer in next reconcile loop. Unfortunately if the provious existing pv has the Failed state, this patch won't take effort. It requires users to remove finalizer. ([#126044](https://github.com/kubernetes/kubernetes/pull/126044), [@carlory](https://github.com/carlory)) [SIG Apps and Storage]

    as a dependency. All other OAuth2 classes inherit from it and customize it for
    each OAuth2 flow.

    You normally would not create a new class inheriting from it but use one of the
    existing subclasses, and maybe compose them if you want to support multiple flows.

    [FastAPI docs for Security](https://fastapi.tiangolo.com/tutorial/security/).

This ensures the endpoint takes roughly the same amount of time to respond whether the username is valid or not, preventing **timing attacks** that could be used to enumerate existing usernames.

#### Key rotation

S3 clients can change the client-provided key of an existing object. Therefore an S3 client must perform a S3 COPY operation where the copy source and destination are equal. Further the COPY request headers must contain the current and the new client key:

                        byte[] nonce = encryptionContext.generateNonce();
                        String nonceHex = bytesToHex(nonce);
                        Integer existing = nonceMap.putIfAbsent(nonceHex, threadId);
                        if (existing != null) {
                            collisions.incrementAndGet();
                        }
                    }

     * constructor have type parameters, the class parameters are prepended before those of the
     * constructor's. This is an arbitrary rule since no existing language spec mandates one way or
     * the other. From the declaration syntax, the class type parameter appears first, but the call
     * syntax may show up in opposite order such as {@code new <A>Foo<B>()}.
