commit 727a60e4d135c53c4d62d708ac4528f7c077c0d0
Author: Mak Mukhi <[email protected]>

    update server reflection code to comply with the change to the grpc generator

Introduces the error:

# github.com/org/repo/vendor/some_grpc_lib
vendor/some_grpc_lib/some_lib.pb.go:173: undefined: grpc.SupportPackageIsVersion3`

The error message is not helpful. I have tried regenerating source files using the latest protoc

$ protoc --version
libprotoc 3.1.0

How can this problem be fixed?
Can you provide a more helpful error message?

[menghanl]

Please make sure proto package, gRPC package are all up to date.

    descriptor: rename generated protobuf package on import.

    This works around https://github.com/google/go-genproto/issues/8,
    renaming the local package to match its expected name.

I guess your vendored gRPC is outdated.
And did you try to regenerate the file you mentioned vendor/some_grpc_lib/some_lib.pb.go?

[erjoalgo]

I'm not aware of any vendored gRPC in my project. Could you please elaborate?

Also I did regenerate the .proto sources.

[menghanl]

In your error message:

# github.com/org/repo/vendor/some_grpc_lib
vendor/some_grpc_lib/some_lib.pb.go:173: undefined: grpc.SupportPackageIsVersion3`

The error happens in some file inside vendor directory. So I guess you are using go vendor.

The original issue can be resolved by updating proto package, gRPC package and rebuilding the proto files. If you are using go vendor, you need to make sure the vendored packages are up to date.

[troylelandshields]

We are having a nightmare of a time dealing with this issue also.

How do you recommend working through it?

Here's an example. We have a developer working on project A who generates their gRPC code with grpc.SupportPackageIsVersion3.

A developer working on project B imports the package with the generated gRPC client from project A. Project B also needs to generate a gRPC server but they generate it with grpc.SupportPackageIsVersion4.

Now the project cannot build.

So you suggest re-generating the protofile from Project A, but this feels weird to us. Now we're changing a vendored file (the generated file) that really should be untouchable since it belongs to Project A.

Also, a lot of our files are difficult to generate in the vendored folder since they rely on imports that are relative to Project's A repo.

Another alternative is to copy/paste the code in the .proto file from Project A to Project B and have Project B generate its own client code. We're duplicating that code and separating it though, so this seems less than ideal as well.

What do you suggest? This really is a huge problem for us and I don't feel like there's a great solution. If you have a single gRPC dependency you are importing then it might be fairly straight-forward, but when you have several that each have several dependencies of their own it becomes a huge pain.

[clintberry]

You need to be like Google and work out of one giant repo for all projects... :troll:

[erjoalgo]

One workaround I used is to build the commit prior to the one in the OP:

cd $GOPATH/src/google.golang.org/grpc
git checkout 727a60e
go install

[tbillington]

I am also encountering this error.

I ran these commands as per https://github.com/grpc/grpc-go#compiling-error-undefined-grpcsupportpackageisversion

go get -u github.com/golang/protobuf/{proto,protoc-gen-go}
go get -u google.golang.org/grpc

Then this command to generate the go proto files

protoc --go_out=plugins=grpc:. *.proto

In one of the generated files there is these lines

// This is a compile-time assertion to ensure that this generated file
// is compatible with the proto package it is being compiled against.
// A compilation error at this line likely means your copy of the
// proto package needs to be updated.
const _ = proto.ProtoPackageIsVersion2 // please upgrade the proto package

And the error says

/Users/trent/src/github.com/abc/proto/go/def/def.pb.go:195: undefined: grpc.SupportPackageIsVersion3

Running protoc --version gives libprotoc 3.1.0

I tried the fix suggested by @erjoalgo but that didn't work.

[iamqizhao]

This is not rocket science. We simply add a variable grpc.SupportPackageIsVersionX (X is the integer and the current value is 4) to make sure your grpc lib and the generated code work on the same version. We think this is a nice feature so that our users won't blindly mess up different version altogether which may have undefined errors and hard to tackle. In general, if you encounter this problem, check this file (https://github.com/golang/protobuf/blob/master/protoc-gen-go/grpc/grpc.go#L51) and this file (https://github.com/grpc/grpc-go/blob/master/rpc_util.go#L481) for both your project and its dependencies (if they also use gRPC) and see whether they are matched. If they are not, update the repo to make them consistent (you probably need to do additional steps if this happens to your dependencies. I do not want to recommend a way here because this highly depends on your best practice.). Once they are consistent, regenerate all the code. The problem should go away.

@troylelandshields Yes it is a huge pain if your project has a deep dependency tree. But this pain is not specific to grpc. Basically it applies to all the libraries which are used in multiple places in the dependency tree. I think the library should ship with its vendored grpc library, which makes the life much easier.

[tbillington]

Thanks @iamqizhao . Issue was an old copy of protoc-gen-go in my path which was in front of github.com/golang/protobuf/protoc-gen-go :) my mistake.

[troylelandshields]

@iamqizhao thank you for reminding me that it's not rocket science.

My point is simply that other non-rocket-scientist people are going to run into this issue as gRPC and Go increase in popularity. They are going to be coming here to look for answers or ask for help as well.

Obviously a lot of thought was put into the decision to add this feature so I think it was fair to assume that we were doing something wrong and you guys must have had a best practice in mind for dealing with this. Apparently the best practice is "deal with it," which is pretty unsatisfactory but we'll figure it out.

[clintberry]

It doesn't have to be a "deep dependency tree". If you have one dependency generated by a different version it fails. Ultimately, I think for Go we won't be importing generated code, but each client/consumer will have to generate the client code for their own project. No dependency and no sharing... for better or for worse. Which may be what you were suggesting...

[orian]

I've encountered this when using: https://hub.docker.com/r/grpc/go

docker run --rm -it -v $PWD/proto:/data grpc/go \ 
  protoc --go_out=plugins=grpc,import_path=data:/data /data/data.proto

It seems that grpc/go image is kind of old. Thus I've downloaded it from: https://github.com/grpc/grpc-docker-library/blob/master/1.0/golang/Dockerfile and recreated. Probably it would make sense refresh the image.

I just hit this while going through Google's "Building a gRPC service with Node.js" codelab, see https://codelabs.developers.google.com/codelabs/cloud-grpc/index.html?index=..%2F..%2Findex#3

Filed an issue in googlecodelabs/cloud-grpc#5 but posting here too in case anyone here is interested or can help. Thanks!

@MakMukhi I did that already and still get the same error. Is there anything else you recommend I try? Thanks for trying to help!

[MakMukhi]

Make sure $GOPATH/bin/protoc-gen-go is the updated binary. If not, delete
it and let it regenerate.
It basically boils down to the fact that your generator and grpc code are
not in sync. You'll need to figure out what needs to be update.

@MakMukhi I just moved aside my entire $GOPATH, reinstalled from scratch, and am getting the same error. Can you not reproduce? Does this show that the issue is not on my end, but rather upstream? Anything else I should try?

books.pb.go is the code that needs to be regenerated. Quick fix: Inside

I'll find out how to get that repo updated.

Also, this could serve as a nice quickstart for grpc-go

books.pb.go is the code that needs to be regenerated. Quick fix: Inside
books dir, run protoc -I . books.pb.go --go_out=plugins=grpc:.
I'll find out how to get that repo updated.

@MakMukhi Thanks for continuing to debug with me. I tried your quick fix and here is what happened:

$ head .git/config

    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true

    fetch = +refs/heads/*:refs/remotes/origin/*
$ git pull

books.pb.go:30:1: Expected ";".
books.pb.go:53:1: Expected top-level statement (e.g. "message").

Anything else you suggest so I can get past this? Thanks again!

[MakMukhi]

Wait, my bad; That needs to books.proto protoc -I . books.proto
--go_out=plugins=grpc:.
But I see that they haven't provided books proto file.
Another quick fix: update the books.pb.go file yourself:

1. Update all occurrences of grpc.SupportPackageIsVersion3 to
   grpc.SupportPackageIsVersion4
2. Replace Metadata: fileDescriptor0 with Metadata: "books.proto"

Hope they update repo soon, meanwhile this should work.

Thanks so much @MakMukhi, I think that did the trick! Added the exact patch to https://github.com/googlecodelabs/cloud-grpc/issues/5#issuecomment-276835746 in case it helps someone else in the future.

[akocmaruk]

Thanks for the review. I'll submit the update later today.

[ceywj]

I solve a similar problem ,
see https://github.com/grpc/grpc-go/releases,
coment on v1.0.4 version is SupportPackageIsVersion4.
so when my protoc-gen-go generate still SupportPackageIsVersion3 , it can not work .
then I download grpc-go v1.0.0, the two version is match, it work again.
