• Are there enough tests
• Documentation has been included (for new feature)

Changes

This pull request introduces significant changes to improve asynchronous handling across multiple modules, enhance efficiency, and ensure non-blocking operations. Key updates include replacing synchronous file and I/O operations with asynchronous alternatives, introducing semaphores to limit concurrent requests, and refactoring code to use shared aiohttp.ClientSession instances for HTTP requests.

Asynchronous Enhancements:

• src/aleph/handlers/content/aggregate.py: Updated _prepend_to_aggregate and _update_aggregate to use asyncio.to_thread for non-blocking execution of merge_aggregate_elements. [1] [2]

• src/aleph/services/storage/fileystem_engine.py: Replaced synchronous file operations with asynchronous equivalents using aiofiles, including read, write, delete, and exists methods.

HTTP Request Optimization:

• src/aleph/services/p2p/http.py: Refactored api_get_request to use a shared aiohttp.ClientSession instead of maintaining separate session instances, improving resource management. Added semaphores to limit concurrent calls in get_peer_hash_content and request_hash. [1] [2] [3]

• src/aleph/services/p2p/jobs.py: Introduced request_version to handle peer version checks using aiohttp.ClientSession and asynchronous tasks. Refactored tidy_http_peers_job to utilize request_version for better scalability. [1] [2]

Code Cleanup:

• src/aleph/handlers/content/post.py: Removed debug print statements from update_balances for cleaner logging.

These changes collectively enhance the system's scalability, responsiveness, and maintainability by leveraging asynchronous programming patterns effectively.
