描述

Description

Implement the LocalMessageUidPrefixProvider logic to retrieve the system-wide prefix used for messages that have not yet been synced with the server.

Goal

Decouple the deletion logic from legacy global constants (like K9.LOCAL_UID_PREFIX), allowing for cleaner testing and dependency injection.

Acceptance Criteria

  • Correctly identifies messages generated locally that do not yet have a server-assigned UID.
  • Replace direct calls from K9.LOCAL_UID_PREFIX to the newly created LocalMessageUidPrefixProvider.get()
  • Testing: Unit tests verifying prefix detection across various message UID formats.

研究方向
Review the current usage of K9.LOCAL UID PREFIX across the codebase, especially in the K9 class. Look at existing provider implementations (e.g., MessageUidProvider) to understand the expected pattern. Examine the issue's comments and linked resources for any additional context. Then, implement LocalMessageUidPrefixProvider with a get() method that returns the prefix, update all references to K9.LOCAL UID PREFIX to use the new provider, and write unit tests that verify correct prefix detection for various message UID formats, including null, empty, and edge cases.
