eth-bytecode-db bug: grpc connection #672

Open sevenzing opened 11 months ago

sevenzing commented 11 months ago

we noted that eth-bytecode-db doesnt response on simple

curl 'https://eth-bytecode-db.services.blockscout.com/api/v2/verifier/solidity/versions'

also, service doesn't log anything. After a restart, error didnt go away. After smart-contract-verifier restart error resolved.

My assumption is that grpc connection between eth-bytecode-db and verifier is lost and couldn't be fixed for some reason. My suggestion is to add logging and investigate the problem. Or move to http connections between services

We've improved logging capabilities for eth-bytecode-db and smart-contract-verifier services, so that now it would be easier to fix the problem if that occurs.

Besides that we are planning to move to the HTTP client for the eth-bytecode-db to send requests to the verifier
