It seems the SafeImplementation has been changed to UnimplementedServer, does it make sense to rename the PR title?

Also, “…can be embedded…” would sound better? Saying “should” here suggests that the full implications must be understood and carefully weighed before choosing a different course. Meanwhile, this is more of a nice optional feature.

FWIW, I would argue embedding this should be considered a best practice for all services. Otherwise, newly added methods will break your code - but adding methods to proto services is not supposed to be a breaking change.

True, but its an optional feature for now, and gives added functionality to those who would want the said safety. Therefore the said language is better.

Hey @dfawley @puellanivis does this look good now?

Looks good to me, with one minor change requested. @dsnet are you OK with merging this after that is addressed?

dfawley · 2019-03-04T18:14:45Z

@dsnet - any concerns with this PR? If not, I think it is ready to be merged.

dsnet · 2019-03-05T21:19:20Z

I'm out of the office till beginning of next week. I can take a look on next Monday.

dfawley · 2019-03-13T23:12:41Z

Friendly ping @dsnet. grpc-go was just broken by a method we didn't implement; this PR would have prevented that.

…re#784

### Release notes - https://github.com/grpc/grpc-go/releases/tag/v1.23.0 - much stuff! a bunch of HTTP2-related fixes -- we don't _expose_ go-grpc's listener, but we use it interally all over the place - there's `*satus.Is` now: grpc/grpc-go#2868 -- we could make some use of that, I suppose. - a bunch of perf improvements, always welcome :) - https://github.com/golang/protobuf/releases/tag/v1.3.2 - small fry, but nice stuff: golang/protobuf#785 adds an Unimplemented method to each server, allowing old servers to be used when there's proto changes. * deps: bump protobuf (1.3.2) and go-grpc (1.23.0) * deps: bump protobuf (1.3.2) and go-grpc (1.23.0) [revendor] * deps: bump protobuf (1.3.2) and go-grpc (1.23.0) [regenerate] Signed-off-by: Stephan Renatus <srenatus@chef.io>

full diff: golang/protobuf@v1.2.0...v1.3.2 protobuf v1.3.2: - golang/protobuf#785: grpc code generation: add an UnimplementedServer type implementing each server interface, returning an unimplemented error for each method - golang/protobuf#851: convert prints to os.Stderr to use log.Printf - golang/protobuf#883: jsonpb: fix marshaling of Duration with negative nanoseconds protobuf v1.3.1: - The set of dependencies specified in go.mod has now been reduced to only the standard library. protobuf v1.3.0: - golang/protobuf#699: add a go.mod module file - golang/protobuf#701: stop generating package "// import" comment - golang/protobuf#741: deprecate {Unm,M}arshalMessageSet{JSON} - golang/protobuf#760: different internal implementation of oneofs - `.pb.go` files generated by protoc-gen-go@v1.3.0 will require the proto@v1.3.0 package to work - various minor changes to code generation Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

Also add deprecation comments on methods. Forward port: golang/protobuf#785 golang/protobuf#952 Fixes golang/protobuf#816 Change-Id: Id4d9f08b39fe16eaf57fb7a92fb8ada222b5cbf4 Reviewed-on: https://go-review.googlesource.com/c/protobuf/+/205246 Reviewed-by: Joe Tsai <thebrokentoaster@gmail.com>
