In all cases, we re-allow further reviews after a brief timeout. Please see our FAQ for further information. WalkthroughRecent updates refine instance and proxy management, notably enhancing proxy integration by relocating methods and adding error handling. Key improvements include a method for checking host readiness and a verification step for Traefik API availability. These changes aim to bolster stability and functionality in a streamlined manner.

Codebase VerificationThe global variable
imageCacheinpkg/instance/instance.gois accessed and modified without any synchronization mechanisms, which can lead to data races in concurrent environments.
pkg/instance/instance.go: imageName, exists = imageCache[imageHash]pkg/instance/instance.go: imageCache[imageHash] = imageName // Update the cache with the new hash and image nameConsider using synchronization primitives like

Codebase VerificationThe manual checks using
ripgreprevealed the following:
- There is a TODO comment in
pkg/instance/instance.goindicating incomplete code.- Numerous commented-out lines of code were found, which might indicate poor code quality or incomplete documentation.
- No instances of
paniccalls were found, which is good as it indicates proper error handling.Given these findings, it is clear that there are some areas in the code that need attention, particularly the TODO comment and the extensive commented-out code.
