But by using the `secrets.compare_digest()` it will be secure against a type of attacks called "timing attacks".

### Timing Attacks

But what's a "timing attack"?

Let's imagine some attackers are trying to guess the username and password.

Then, when it's your turn, you do actual "productive" work, you process the menu, decide what you want, get your crush's choice, pay, check that you give the correct bill or card, check that you are charged correctly, check that the order has the correct items, etc.

## Parameterized dependencies

All the dependencies we have seen are a fixed function or class.

But there could be cases where you want to be able to set parameters on the dependency, without having to declare many different functions or classes.

Let's imagine that we want to have a dependency that checks if the query parameter `q` contains some fixed content.

But we want to be able to parameterize that fixed content.

## A "callable" instance

		t.Errorf("should got failed to save, but error is nil")
	}

	if DB.First(&Product4{}, "name = ?", product.Name).Error == nil {
		t.Errorf("should got RecordNotFound, but got nil")
	}

	product = Product4{Name: "Product-2", Price: 100, Item: ProductItem{Code: "valid"}}
	if err := DB.Create(&product).Error; err != nil {
		t.Errorf("should create product, but got error %v", err)
	}

   * valueFunction)))} behaves similarly, but may not preserve the order of entries.
   *
   * @throws NullPointerException if any element of this iterable is {@code null}, or if {@code
   *     valueFunction} produces {@code null} for any key

   */
  @SuppressWarnings("nullness") // Unsafe, but we can't do much about it now.

      // But theoretically we could see sneaky checked exception
      sneakyThrow(exception);
    }
  }

  /** Throws an undeclared checked exception. */
  private static void sneakyThrow(Throwable t) {
    class SneakyThrower<T extends Throwable> {
      @SuppressWarnings("unchecked") // not really safe, but that's the point
      void throwIt(Throwable t) throws T {

But whenever you need them and go and learn them, know that you can already use them directly in **FastAPI**.

### Pydantic v1 `regex` instead of `pattern`

Before Pydantic version 2 and before FastAPI 0.100.0, the parameter was called `regex` instead of `pattern`, but it's now deprecated.

You could still see some code using it:
