## 监听 GitHub 资源库

您可以在 GitHub 上「监听」FastAPI（点击右上角的 "watch" 按钮）： <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">https://github.com/fastapi/fastapi</a>. 👀

如果您选择 "Watching" 而不是 "Releases only"，有人创建新 Issue 时，您会接收到通知。

然后您就可以尝试并帮助他们解决问题。

## 创建 Issue

您可以在 GitHub 资源库中<a href="https://github.com/fastapi/fastapi/issues/new/choose" class="external-link" target="_blank">创建 Issue</a>，例如：

	deleteGroupInfo(ctx context.Context, name string) error
}

// iamStorageWatcher is implemented by `IAMStorageAPI` implementers that
// additionally support watching storage for changes.
type iamStorageWatcher interface {
	watch(ctx context.Context, keyPath string) <-chan iamWatchEvent
}

// Set default canned policies only if not already overridden by users.

        return dataStoreMap.get(name.toLowerCase(Locale.ROOT));
    }

    /**
     * Returns an array of available data store names discovered from plugin JAR files.
     * This method implements a time-based caching mechanism that refreshes the list
     * every 60 seconds to balance performance with up-to-date plugin discovery.
     *
     * @return array of data store names sorted alphabetically, never null
     */

> **NOTE:** Do **NOT** run `gradle build` on the local development environment,

> The Gradle Build Tool repository is massive, and it will take ages to build on

> The full test suites are executed on the CI instance for multiple configurations,

Вы можете "отслеживать" FastAPI на GitHub (кликнув по кнопке "watch" наверху справа): <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">https://github.com/fastapi/fastapi</a>. 👀

Если Вы выберете "Watching" вместо "Releases only", то будете получать уведомления, когда кто-либо создаёт новый вопрос или Issue. Вы также можете указать, что хотите получать уведомления только о новых Issues, или обсуждениях, или пулл-реквестах и т.д.

## Patching guidelines

Follow these steps to patch a specific version of TensorFlow, for example, to
apply fixes to bugs or security vulnerabilities:

*   Clone the TensorFlow repository and switch to the appropriate branch for
