Summary of Changes
Hello @nazarhussain, 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 primarily focuses on enhancing the robustness and testability of the beacon node's synchronization mechanism, particularly concerning upcoming network upgrades. It introduces a dedicated end-to-end test to simulate and validate finalized sync behavior across specific hard forks, alongside improvements to internal data handling and debugging outputs. The changes aim to ensure reliable node operation and provide better insights into sync processes.
Highlights
- End-to-End Test for Electra and Fulu Finalized Sync: A new end-to-end test has been introduced to validate the finalized synchronization process specifically for nodes starting from the Electra fork and progressing through the Fulu fork. This test ensures that a beacon node can successfully catch up and finalize blocks across these critical network upgrades.
- Enhanced Logging and Error Messaging: Improved debugging capabilities by adding more detailed logging information for data column sidecars during block persistence and by providing more comprehensive error messages when blocks are not found during range synchronization requests. These enhancements will aid in diagnosing sync-related issues more effectively.
- Unit Test for Data Column Sidecar Archiving: A new unit test has been added to verify the proper migration and retrieval of data column sidecars to and from an archived database. This test is crucial for ensuring the integrity and accessibility of historical data, supporting efficient data management within the beacon node.

Code Review
This pull request introduces an end-to-end test for finalized sync in a post-Electra (Fulu) context, which is a valuable addition for ensuring sync functionality. The changes also include helpful enhancements to logging and error messages for better debugging, and good refactoring in the database repository tests to improve code structure. I have one suggestion regarding a misleading comment in the new e2e test that could cause confusion for future readers.
