Description

Closes: #XXXX

In order to overwrite a default genesis from the SDK module we have to wrap the AppModule. Since the SDK modules are automatically supplied ot depinject in the init function, we need to unregister them, before registering the wrapped AppModule.

Use case: the default bank DenomMetadata is empty. I want to predefine denoms into it.

The flow is:

  1. Create a custom bank module that wraps the sdk bank module
  2. Implement UnergisterModule function -- this PR
  3. Unregister the SDK bank module, and register the wrapped one

📝 Walkthrough

Walkthrough

The changes involve updates to the depinject module, specifically in the appconfig package. A new function UnregisterModule has been introduced, allowing the removal of previously registered modules from the global module registry. A helper function modouleProtoType was added to streamline type checking for module configurations. The changes aim to improve code modularity and provide more flexibility in module management.

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>, please review it.
    • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @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.
    • @coderabbitai help me debug CodeRabbit configuration file.

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.

14-21: Possible Typo in Function Name.
The function name modouleProtoType appears to have a misspelling. Consider renaming it to moduleProtoType for clarity and consistency.


14-21: Use of Panic.
Currently, the code panics if the module isn't a proto.Message. For production-level robustness, consider handling the error gracefully and returning a descriptive error instead.

⚠️ Potential issue

Potential Race Condition in Global Registry.
delete(internal.ModuleRegistry, ty) is performed on a global map. Without synchronization, if multiple goroutines register or unregister modules concurrently, data races can occur. Consider adding a mutex around ModuleRegistry operations to ensure thread safety.
