- If you edit, you’re a collaborator, not a reviewer, and cannot merge.

6. **Testing**:
   - Assume the submitter tested the code. If testing is unclear, ask for details (e.g., “How was this tested?”).
   - Reject untested PRs unless testing is infeasible, then assist with test setup.

## Common Development Tasks

### Adding a Protocol Client

1. **Implement `CrawlerClient`**:
```java
public class MyClient extends AbstractCrawlerClient {
    @Override

    * It contains the `username` and `password` sent.

{* ../../docs_src/security/tutorial006_an_py39.py hl[4,8,12] *}

When you try to open the URL for the first time (or click the "Execute" button in the docs) the browser will ask you for your username and password:

<img src="/img/tutorial/security/image12.png">

## Check the username { #check-the-username }

Here's a more complete example.

    int ATTR_COMPRESSED = 0x800;
    /** Normal file attribute */
    int ATTR_NORMAL = 0x080;
    /** Temporary file attribute */
    int ATTR_TEMPORARY = 0x100;

    // access mask encoding
    /** File read data access right */
    int FILE_READ_DATA = 0x00000001; // 1
    /** File write data access right */
    int FILE_WRITE_DATA = 0x00000002; // 2
    /** File append data access right */

    assertEquals(Sets.<@Nullable String>newHashSet(null, "tree"), keySet.headSet("yahoo"));
    assertEquals(newHashSet("google"), keySet.tailSet("yahoo"));
    assertEquals(newHashSet("tree"), keySet.subSet("ask", "yahoo"));
  }

  @GwtIncompatible // SerializableTester
  public void testExplicitComparatorSerialization() {
    TreeMultimap<@Nullable String, @Nullable Integer> multimap = createPopulate();

* En muchos casos, es mejor entender su **problema subyacente o caso de uso**, porque podría haber una mejor manera de resolverlo que lo que están intentando hacer.

### Pide cerrar { #ask-to-close }

Si responden, hay una alta probabilidad de que hayas resuelto su problema, felicidades, ¡**eres un héroe**! 🦸

* Ahora, si eso resolvió su problema, puedes pedirles que:

          * Read open questions until I find 2 where I can help someone and add a comment to help there.
          * I already hit the "watch" button in this repository to receive notifications and I commit to help at least 2 people that ask questions in the future.
          * Review one Pull Request by downloading the code and following [all the review process](https://fastapi.tiangolo.com/help-fastapi/#review-pull-requests).

      options:

  PodSubnet validates against the corresponding cluster "--node-cidr-mask-size" of the kube-controller-manager, it fail if the values are not compatible.
  kubeadm no longer sets the node-mask automatically on IPv6 deployments, you must check that your IPv6 service subnet mask is compatible with the default node mask /64 or set it accordingly.
