# SMB3 Lease Feature - Detailed Design Document

## 1. Overview

SMB3 leases provide a client caching mechanism that replaces the traditional oplock mechanism. Leases enable better performance through client-side caching while maintaining cache coherency across multiple clients.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13**: SMB2 CREATE Request with Lease Context
- **MS-SMB2 Section 2.2.14**: SMB2 CREATE Response with Lease State

所有的這些都是可重複使用的工具和套件，可以輕鬆與你的系統、資料儲存（Data Stores）、關聯式資料庫（RDBMS）以及非關聯式資料庫（NoSQL）等等整合。


### 依賴注入（Dependency Injection）

FastAPI 有一個使用簡單，但是非常強大的<abbr title='也叫做 "components", "resources", "services", "providers"'><strong>依賴注入</strong></abbr>系統。

* 依賴項甚至可以有自己的依賴，從而形成一個層級或**依賴圖**的結構。
* 所有**自動化處理**都由框架完成。
* 依賴項不僅能從請求中提取資料，還能**對 API 的路徑操作進行強化**，並自動生成文檔。
* 即使是依賴項中定義的*路徑操作參數*，也會**自動進行驗證**。
* 支持複雜的用戶身份驗證系統、**資料庫連接**等。

          throw new AssertionFailedError("You weren't supposed to actually invoke me!");
        }
      };

  public void testAnyAndNone_logicalOps() throws Exception {
    // These are testing behavior that's never promised by the API, but since
    // we're lucky enough that these do pass, it saves us from having to write
    // more excruciating tests! Hooray!

    assertSame(CharMatcher.any(), CharMatcher.none().negate());

  // TODO(user): Consider separating Strings that we've defined here to capture
  // identifiable substrings of expected error messages, from Strings that we've defined
  // here to provide error messages.
  // TODO(user): Some Strings used in the subclasses can be added as static Strings
  // here too.
  static final String ERROR_PARALLEL_EDGE = "connected by a different edge";

# Tensorflow to the default, however test coverage wasn't enough to catch the
# errors.
# There is ongoing work on Bazel team's side to provide support for transitive
# shared libraries. As part of migrating to transitive shared libraries, we
# hope to provide a better mechanism for control over symbol exporting, and
# then tackle this issue again.
