chore: optimized range loops #215
Conversation
WalkthroughThis pull request introduces a consistent code refactoring approach across multiple files in the project. The primary change involves simplifying code by eliminating intermediate variables when iterating over function results. These modifications are applied in various keeper and query-related files, focusing on methods that retrieve and process pool accounts, staker addresses, and fundings. The changes aim to enhance code readability and reduce unnecessary variable declarations while maintaining the original logic and functionality. Changes

: Discuss potential performance cost for large staker sets
If a large number of stakers belong to the pool, iterating over them in a single pass could be expensive. Consider chunking or batching to handle large-scale scenarios more efficiently.

Learning: The `GetValidatorPoolStakes()` method ensures that the effective stake cannot exceed the validator's total bonded tokens, so no additional check is necessary.

: Inline iteration aligns with the code simplification
This adjustment is consistent with the approach of removing intermediate variables. It preserves functionality while improving readability.

: Simplified iteration without altering functionality
Replacing the intermediate variable with direct iteration promotes clarity and maintains the original logic.

: Guard against potential uint64 overflow
If the total stake grows large, there's a possibility of exceeding the uint64 range.
Would you like a script to search for all references to this function and check if the accumulated stake could exceed uint64 limits?

: Prevent overflow when adding multiple validator stakes
Similar to the previous snippet, verify the aggregated stake won't exceed uint64 capacity.
✅ Verification successful
Let me gather more context about the code to verify the overflow concern.
Let me try a different approach to find the relevant code.
Let me look for the function that uses this loop to understand how the stakes are aggregated.
Let me check how GetValidatorPoolStake handles the stake values.
Let me check how GetValidatorPoolStakes handles the stake values and overflow protection.
Let me try a different approach to find the stake handling code.
Let me check the rest of the GetValidatorPoolStakes implementation.
Let me get the final part of the GetValidatorPoolStakes function.
After analyzing the code, I can now generate the final response regarding the overflow concern.
No overflow risk in stake aggregation
The GetValidatorTotalPoolStake
function is safe from overflow because:
- Individual pool stakes are already bounded by the validator's bonded tokens and stake fraction
- The
GetValidatorPoolStakes
function uses safe math operations withTruncateInt64()
and explicit uint64 conversions - The total stake is reduced rather than increased through the max voting power mechanism and scaling factor
