Summary of Changes
Hello @ellemouton, 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 refactors several instances where Go maps were being reset by assigning nil to them. Instead, it now utilizes the clear built-in function, which is the idiomatic and correct way to empty a map's contents while preserving its underlying memory and avoiding potential issues with subsequent operations. This change ensures robust and predictable map behavior across different parts of the codebase.
Highlights
- Map Resetting: Replaced direct
nilassignment to maps with theclearbuilt-in function for proper map resetting. - Bug Fix: Addresses a bug where maps were not being correctly reset, potentially leading to unexpected behavior or runtime issues.

Code Review
This pull request correctly fixes a potential panic by replacing nil assignments to maps with the clear() built-in function. This is the modern and correct way to reset a map in Go, as it avoids deallocation and prevents panics when writing to a map that could be nil. The changes in autopilot/agent.go, discovery/bootstrapper.go, and rpcserver.go are consistent and improve the code's robustness. The fix is well-implemented.
