描述

I was able to break my local ipns publishing:

➜  ~ ipfs name publish <some hash>
Error: proto: required field "{Unknown}" not set

I did this by first publishing an entry normally, then:

ipfs dht get /ipns/<my peer ID> > ipns-data
cat ipns-data | ipfs dht put /ipns/<my peer ID>

Something must not be quite right here in the round tripping of the record.

This also appears to make it impossible for me to publish new ipns values for the time being.

研究方向
Investigate the IPNS record serialization and deserialization in the Go IPFS implementation. The error suggests a required protobuf field is missing after a DHT put/get round trip. Examine the ipns package's Record type and the DHT's handling of raw data. Also review the protobuf definitions for IPNS records to ensure all fields are preserved.
