Unfortunately, the mechanism used to forward the cache settings into the algorithms that need it is not ok.

func MakeGossipDb(ctx *cli.Context, dbs kvdb.FullDBProducer, dataDir string, validatorMode bool, cacheRatio cachescale.Func) (*gossip.Store, error) {

This function already includes parameters deduced from the command line, additionally this is too late to parse command line arguments, ranges are not checked, and faulty values will be propagated to internal components for undefined behavior.

Please perform the command line arguments parsing the outermost possible layer of the program, sanitize arguments and return an error to the user as early as possible.

To avoid aliasing arguments into the program logic functions (like func x( bool, int , float ,int) I propose alternatives:

1. pack all configuration arguments from a function into a struct (this way you can add names to the funciton call side)

callFunction(configuration{
     argument1: 1,
     argument2: 2,
     })

2. Pack single arguments into a struct (same effect, naming one argument at the time).

3. Use a builder pattern (may be a little too heavy for this use case).
