fix: Do not call Remove during Walk - part 2 #19851
Conversation
WalkthroughWalkthroughThe recent updates focus on optimizing the handling of proposals and validators within the blockchain's governance and staking modules. Specifically, enhancements have been made to efficiently process inactive and active proposals, including error management and state updates. Additionally, the system now better manages the unbonding of mature validators by streamlining the iteration and error handling processes. These changes aim to improve the overall efficiency and reliability of these critical operations. Changes

- 30-39: The use of
KeyValuesto retrieve all inactive proposals at once before processing them is a good approach to avoid modifying the collection while iterating over it. This change aligns with the PR's objective to enhance robustness by avoiding direct modifications during iteration.- 40-56: When handling encoding errors for proposals, the decision to fail the proposal instead of halting the chain is prudent. This approach ensures that transient issues with proposal encoding do not disrupt the overall chain operation. However, it's essential to ensure that such failures are logged and monitored to address any systemic issues promptly.
- 106-118: Similar to handling inactive proposals, the approach to first gather all active proposals using
KeyValuesbefore processing them is effective in avoiding collection modification during iteration. This method is consistent with best practices for handling collections in concurrent environments.- 119-136: The logic for failing unsupported proposals due to encoding errors is consistent with the handling of inactive proposals. This consistency in error handling across different parts of the
EndBlockerfunction contributes to the maintainability of the code.- 101-149: > 📝 NOTE

The detailed handling of proposal outcomes based on the tally results, including the conditions for burning or refunding deposits, is well-implemented. The decision to log errors without halting the chain in case of issues with refunding or burning deposits is a pragmatic approach to ensure chain continuity. However, it's crucial to monitor these logs to address any recurring issues.
- 230-237: The logic to convert expedited or optimistic proposals that fail into regular proposals by extending the voting period and updating the queue is a thoughtful feature. It allows for a second chance for proposals that might have been prematurely judged, enhancing the governance process's flexibility.

The comprehensive logging and event emission at the end of the proposal tallying process provides valuable insights into the proposal outcomes. This level of detail aids in transparency and auditability of the governance process.

- 497-514: The refactoring of
UnbondAllMatureValidatorsto first gather all key-value pairs usingKeyValuesbefore processing them is a solid approach that aligns with the PR's objective. This method avoids potential issues with modifying the collection during iteration and enhances the function's robustness and reliability.

Description
Follow up to #19833
Instead of calling Walk, I first gather all the keys in a slice and iterate through that.
