Re: [protobuf] Compatibility error on adding sub message type in existing proto file

[Robert Yokota]

Hi,

I believe this is coming from the Confluent compatibility checker.  (I work
for Confluent.)

A forward compatibility check is just a backward compatibility check with
the arguments reversed.  Since removing a message is not backward
compatible, adding a message is not forward compatible.

Hope that helps,
Robert

Re: [protobuf] Compatibility error on adding sub message type in existing proto file

['Adam Cozzette' via Protocol Buffers]

I don't think we maintain any code that returns that kind of error. Do you
know where that error is coming from? Is it from some external protobuf
compatibility checker?
