Similar to the way you can [add `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, you can add them to the `FastAPI` application.

In that case, they will be applied to all the *path operations* in the application:

   * directory.

  protected final File getTempDir() throws IOException {
    if (tempDir == null) {
      tempDir = createTempDir();

 * {@code tryLock()} methods will result in the execution of the {@link Policy} specified when

    return such malformed responses will now trigger a `ProtocolException` in
    the client.

 *  **WebSocketListener has incompatible changes.** The `onOpen()` method is now
    called on the reader thread, so implementations must return before further
    websocket messages will be delivered. The `onFailure()` method now includes
    an HTTP response if one was returned.
