Can you add a connection ID to all connections and logging, to connect log entries to connections?
Can you add a connection ID to all connections and logging, to connect log entries to connections?
I'll help you add connection IDs to all connections and logging in the pest control server. Let me first examine the current server implementation to understand the structure.

"command": "rm test_connection_id.py test_output.log",
"description": "Clean up test files"
}Perfect! I've successfully added connection IDs to all connections and logging in the pest control server. Here's what was implemented:
Connection ID Generation: Added a simple counter for client connections (client-1, client-2, etc.) and created unique IDs for authority connections (authority-site-{site_id})
Updated All Logging: Modified all logging statements throughout the server to include connection IDs in the format [conn_id]
Authority Connection Tracking: Updated the authority connections dictionary to store a 3-tuple (reader, writer, auth_conn_id) instead of just (reader, writer)
Method Signatures: Updated all relevant method signatures to accept and pass connection IDs:
handle_hello(), send_hello(), send_error(), send_ok()read_message(), handle_site_visit(), update_policies()Cross-Connection Logging: For policy operations, logs now show both client and authority connection IDs like [client-1|authority-site-123]
The test showed that connection IDs are working correctly:
client-1, client-2, client-3)Now all log entries can be easily traced back to specific connections, making debugging and monitoring much easier.
