This PR is a follow up to #2719. The implementation of the DeductFeeDecorator is identical to the one in the Cosmos SDK after removing the staking rewards withdrawal, so we don't need to keep these separate files anymore.

Walkthrough

The changes enhance the efficiency of fee handling in the Cosmos SDK by streamlining the ante module. Key components, such as the removal of unnecessary handlers and parameters in newCosmosAnteHandler, simplify fee deduction logic. Additionally, the reduction of testing utilities leads to a cleaner codebase, supporting better alignment with Cosmos standards. Overall, these updates signify a dedication to refining functionality while maintaining simplicity in the application.

Changes

File Change Summary
CHANGELOG.md Updated to highlight the removal of an unnecessary fee ante handler and correct module designation for pruning.Cmd.
app/ante/cosmos.go Modified newCosmosAnteHandler to remove DistributionKeeper and StakingKeeper, simplifying fee deduction logic.
app/ante/cosmos/utils_test.go Removed utility functions setupDeductFeeDecoratorTestCase and intSlice, resulting in a leaner and cleaner test file.

Poem

In the garden where the bunnies play,
Code's now simpler, hip-hip-hooray!
Fees are handled with care and delight,
Cosmos standards shining bright.
With less to manage, we hop and cheer,
A cleaner codebase is finally here! 🐇✨

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.
    • @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.

Line range hint 1-1:
Verify the sufficiency of the remaining test coverage.

The removal of intSlice suggests a potential simplification in the test suite. Ensure that the test coverage remains sufficient.


Line range hint 1-1:
Verify the sufficiency of the remaining test coverage.

The removal of setupDeductFeeDecoratorTestCase suggests a shift in the testing strategy. Ensure that the test coverage remains sufficient.

Verification successful

Verify the sufficiency of the remaining test coverage.

The removal of setupDeductFeeDecoratorTestCase suggests a shift in the testing strategy. However, the search results indicate that fee deduction is still being tested across various files. The test coverage for fee deduction remains sufficient.
