dot/rpc: Implement RPC system_name, system_version, system_chain #849
Conversation
instead of go struct so that it can be build dynamically later based on genesis definition.

I've refactored this, it's ready for review. |

does this exclude it from the config file?

this looks good! however, it doesn't look like it's started when the node is started in dot NewNode?

I don't have this started because there is no go routine to start, so I guess it's not really a service. It's currently a place to hold static chain and app values. Should I implement the Service interface to add the Start and Stop functions and add call to start so it's treated like other services (for consistency, and in case we add a go routine later). OR should I treat this differently since it's not really a service, and if so, how?

Maybe it could be be part of the rpc or core service?

maybe just rename it from Service to Info or something like that, since there isn't a need to make it into an actual service

I made it implement the Service interface, so it's handled like the others. I was running into issues with cyclic references when I tried making it a part of rpc service. This seems ok since it's following the pattern (now) that we're using for the others.

This looks great! You mentioned wanting to make changes on the call. Are you planning on initializing the system service in the dot node initialization process as part of this pull request?
If you think it is going to be a service (adhere to the service interface) and should be its own service, I think it works as is. Approved as is if you were planning or would prefer to save those changes.

was this intentionally moved?

no, maybe my IDE did it when I did goimports? not sure.
* implement RPC call system_name, system_version * implement RPC call system_chain * added tests * save commit, refactoring rpc module * move system rpc api to it's own package * treat system_properties response as map instead of go struct so that it can be build dynamically later based on genesis definition. * make system service implement Service interface
