refactor(x/slashing): audit x/slashing changes #21270
Conversation
WalkthroughWalkthroughThe changes across the Cosmos SDK's slashing module enhance clarity and performance. Key updates include improved error handling, streamlined address initialization, and refined documentation. The handling of validator signatures is now more robust, with comments and workflows optimized for readability. These adjustments not only clarify existing logic but also prevent potential runtime issues, ultimately contributing to a more maintainable codebase. Changes

18-20: Clarify comment for better understanding.The comment should be more explicit about the process of handling validator votes and the consequences of missed blocks.
- // Retrieve CometBFT info, then iterate through all validator votes - // from the last commit. For each vote, handle the validator's signature, potentially - // slashing or unbonding validators who have missed too many blocks. + // Retrieve CometBFT information and iterate through all validator votes + // from the last commit. For each vote, process the validator's signature + // to determine if slashing or unbonding is necessary due to missed blocks.

Ensure error handling covers all edge cases.The
BeginBlockerfunction handles errors fromParams.GetandHandleValidatorSignatureWithParams. Consider logging these errors for better traceability and debugging.if err != nil { // Log the error for better traceability return err }

Verify the impact of receiver type change.The change from
KeepertoQuerieras the receiver type suggests a shift in responsibility. Ensure that this change aligns with the architectural design and does not introduce inconsistencies.Verification successful
Receiver Type Change Verified
The change from
KeepertoQuerieras the receiver type for theSigningInfoandSigningInfosfunctions is consistent with the architectural design. There are no inconsistencies found in the implementation.Scripts executed

49-49: Ensure consistency in consensus address handling.The use of
consStrdirectly in theQuerySigningInfoRequestimproves clarity. Ensure thatconsStris correctly initialized and used consistently across test cases.
59-62: Simplify consensus address initialization.The direct use of string literals for
consAddr1andconsAddr2enhances readability. Ensure that these changes are consistently applied across all relevant test cases.x/slashing/keeper/keeper.go (3)
93-93: Typo correction in comments approved.The correction of "intraction" to "infraction" in the comment improves clarity.
