Refactor/design smells

[JAYDIPSINH27]

Motivation:

Refactoring the Design Code Smells Without Breaking its functionality.
Main focus on Design Code Smells.
Tool Used for Code Smell Analysis: DesigniteJava(https://www.designite-tools.com/products-dj)

Modification:

• Class Name:
  o BatchRawKVStore (package com.alipay.sofa.jraft.rhea.storage)

• Cause of Smell:
  o Insufficient Modularization
  o The tool detected the smell in this class becuase the class has bloated interface (large number of public methods). Total public methods in the class: 20 public methods.

• Class Name:
  o AtomicServer (package com.alipay.sofa.jraft.test.atomic.server)
  o StartupConf (package com.alipay.sofa.jraft.test.atomic.server)

• Cause of Smell: Feature Envy

• Class Name:
  o CounterServiceImpl (package com.alipay.sofa.jraft.example.counter)
  o CounterServer (package com.alipay.sofa.jraft.example.counter)
  o (Introduced) CounterServiceProvider (package com.alipay.sofa.jraft.example.counter)

• Cause of Smell:
  o Cyclically-dependent Modularization

Walkthrough

The updates introduce a new CounterServiceProvider interface, enhancing the counter example with a more modular design. Additionally, batch operation capabilities are expanded in the key-value store component, with specific classes for put and delete operations. The atomic server test module sees a significant refactor, including a shift in initialization logic to the main method and improvements in server configuration handling.

"In the realm of code, where logic intertwines,
🐇 A rabbit hopped, leaving changes behind.
With a flick and a hop, a new design unfurled,
Modular, efficient, a better digital world.
Through the fields of data, so vast and wide,
It leaps with joy, for progress cannot hide.
🎉 Celebrate, for in the code, new paths are spun,
A journey continued, a new chapter begun."

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• The JSON schema for the configuration file is available here.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/coderabbit-overrides.v2.json

19-21: The introduction of the CounterServiceProvider interface is a good practice for decoupling dependencies and enhancing modularity. Well done!

jraft-rheakv/rheakv-core/src/main/java/com/alipay/sofa/jraft/rhea/storage/BatchRawDeleteOperations.java (1)

24-51: The creation of BatchRawDeleteOperations class to encapsulate batch delete operations is a solid approach to improving code modularity and maintainability. Good job!

jraft-rheakv/rheakv-core/src/main/java/com/alipay/sofa/jraft/rhea/storage/BatchRawPutOperations.java (1)

24-52: The introduction of BatchRawPutOperations class to encapsulate batch put operations is an excellent move towards enhancing code modularity and clarity. Nicely done!

jraft-test/src/main/java/com/alipay/sofa/jraft/test/atomic/server/AtomicServer.java (2)

47-50: Consider adding getters and setters for the fields nodes, groups, totalSlots, and conf to maintain encapsulation and protect the class's invariants.

---

73-74: The refactoring of the server's initialization and startup processes to use StartupConf is a positive change that simplifies setup and enhances code readability.

47-57: > 📝 NOTE

This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [39-53]

Implementing CounterService and CounterServiceProvider in CounterServiceImpl and adding the getCounterService() method is a smart approach to decouple dependencies and improve modularity. Excellent work!

jraft-example/src/main/java/com/alipay/sofa/jraft/example/counter/CounterServer.java (2)

49-50: The modification to the CounterServer constructor to accept a CounterServiceProvider is a commendable approach to decoupling dependencies and enhancing modularity.

The implementation in the main method to create and use a CounterServiceProvider instance for initializing CounterServer is well-aligned with the goal of reducing cyclic dependencies. This is a solid design choice.

jraft-rheakv/rheakv-core/src/main/java/com/alipay/sofa/jraft/rhea/storage/BatchRawKVStore.java (1)

30-59: The addition of batchRawPutOperations and batchRawDeleteOperations fields and the refactoring of batch operations to use these fields significantly improve the modularity and maintainability of the BatchRawKVStore class. This is a great example of applying the Single Responsibility Principle.

jraft-test/src/main/java/com/alipay/sofa/jraft/test/atomic/server/StartupConf.java (1)

154-193: The refactoring to encapsulate the server's initialization and startup processes within StartupConf enhances code readability and maintainability. However, consider encapsulating the logic that directly manipulates AtomicServer's fields within the AtomicServer class itself to maintain encapsulation and separation of concerns.
