Debt Whiteboard

A Whiteboard for collecting engineering debt. This will get translated into a prioritization effort.

Portlayer exec component needs a complete rework

• handle mechanism needs more thought; we currently don’t have a good way to persist handles across portlayer components
• event handling is haphazard; needs to be more feature rich in terms of filtering events, as well as a cleanup of which events are handled where (there are places where we handle the same event more than once)
• hard to add more event handling for OOB operations, and hard to integrate with vm register/unregister events.

Portlayer network component:

• Most of the data structures need to be put behind interfaces
• IPAM code needs to be simplified

Logging:

• Not consistent at all across components; we need a logging package that will enforce one logging format across components
• Multiline logging is not supported, leading to stack traces in logs that are difficult to read
• trace package needs some work
• trace.Operation needs to be re-evaluated; I am not sure we need to replace “context” across our APIs with it

Tether:

• Should be a complete rewrite in my opinion

DHCP client:

• we should use an external well-tested library or command line tool, and deprecate our in-house client

vic machine

• Should separate standard output and log. Now standard output will show all log messages, especially some message printed out by common library is misleading for customer
