Status of delete marker replication can be viewed by doing a GET/HEAD on the object version - it will return a `X-Minio-Replication-DeleteMarker-Status` header and http response code of `405`. In the case of permanent deletes, if the delete replication is pending or failed to propagate to the target cluster, GET/HEAD will return additional `X-Minio-Replication-Delete-Status` header and a http response code of `405`.

        // proceed. So we cannot yet null out each bin.
        E head = oldTable.get(oldIndex);

        if (head != null) {
          E next = head.getNext();
          int headIndex = head.getHash() & newMask;

          // Single node on list
          if (next == null) {
            newTable.set(headIndex, head);
          } else {

            separator = " "
        )

    params {
        // Override the default commit id so the build steps produce reproducible distribution
        param("env.BUILD_COMMIT_ID", "HEAD")
    }

You send it a token and it returns an authenticated user.

This provider might be charging you per request, and calling it might take some extra time than if you had a fixed mock user for tests.

You probably want to test the external provider once, but not necessarily call it for every test that runs.

   * <p>Any existing entry spanning either range boundary may be split at the boundary, even if the

开发 API 时，「路径」是用来分离「关注点」和「资源」的主要手段。

#### 操作

这里的「操作」指的是一种 HTTP「方法」。

下列之一：

* `POST`
* `GET`
* `PUT`
* `DELETE`

...以及更少见的几种：

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

在 HTTP 协议中，你可以使用以上的其中一种（或多种）「方法」与每个路径进行通信。

---

在开发 API 时，你通常使用特定的 HTTP 方法去执行特定的行为。

通常使用：

* `POST`：创建数据。
* `GET`：读取数据。
* `PUT`：更新数据。
