Summary of Changes

Hello @grishasobol, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refining the ethexe project's consensus and configuration aspects. It removes the validate-chain-deepness-limit feature, simplifying node configuration and reducing complexity. A major overhaul of the chain commitment aggregation process introduces more explicit error handling and robustness, particularly for uncomputed announces. Additionally, the PR includes significant refactoring of core data structures for better clarity and enhances the validator election mechanism with more precise timestamp calculations and comprehensive error management, contributing to a more stable and maintainable codebase.

Highlights

• Configuration Simplification: The validate-chain-deepness-limit configuration option and all related logic have been entirely removed from the node parameters, common constants, and validator core, streamlining the system's setup.
• Enhanced Chain Commitment Aggregation: The aggregate_chain_commitment function has been refactored into try_aggregate_chain_commitment to enforce stricter error handling, explicitly bailing on uncomputed announces and removing the max_deepness parameter. It also includes logging for prolonged aggregation processes.
• Data Structure Renaming for Clarity: Core data structures FullBlockData and FullAnnounceData have been renamed to PreparedBlockData and ComputedAnnounceData respectively, improving semantic clarity and consistency across the codebase.
• Refined Validator Election Logic: The mechanism for calculating era and election timestamps has been made more precise, and the validator commitment aggregation now incorporates more robust checks and error handling for various scenarios, such as already committed validators or missing historical block data during fast sync.
• Improved ROAST Key Generation: The process of generating ROAST keys for validators has been separated into its own function (generate_roast_keys) and now includes more explicit error handling, enhancing reliability.

Code Review

This pull request introduces several significant improvements to the consensus logic. The primary change is the removal of the validate-chain-deepness-limit configuration, simplifying the validation process. Concurrently, error handling has been substantially improved, particularly in the chain commitment aggregation logic. The aggregate_chain_commitment function has been refactored into try_aggregate_chain_commitment, which now provides more robust and explicit error handling instead of returning optional values. Similarly, the logic for aggregating validator commitments has been made more resilient with better-defined state checks and error conditions. I've identified one area concerning the handling of missed validator commitments that could be made more robust to ensure chain integrity. Overall, these changes enhance the clarity, correctness, and maintainability of the codebase.
