This change appears to be bad.

The go.sum file contains at least one entry that differs to the actual hash of the content.

To reproduce:

$ git clone https://github.com/dgraph-io/dgraph
$ cd dgraph/chunker
$ go test
go: downloading go.etcd.io/etcd v0.0.0-20190228193606-a943ad0ee4c9
go: downloading github.com/dgraph-io/ristretto v0.0.0-20190903064322-eb48d2f7ca30
verifying github.com/dgraph-io/[email protected]: checksum mismatch
	downloaded: h1:2ymRTEtPu60vzv+YTIHHlJ3713Bl3G/MPc2BOc/OkzM=
	go.sum:     h1:FkdGlqxPjfHKdVUzS5dOSMeOkGjEG7PnR1RLbcEqw88=

SECURITY ERROR
This download does NOT match an earlier download recorded in go.sum.
The bits may have been replaced on the origin server, or an attacker may
have intercepted the download attempt.

@adg thanks for pointing out. Fixed in #4153

@mangalaman93 @campoy I've updated my Dgraph version to master, but i'm still getting the error.

github.com/dgraph-io/dgraph/protos/pb
../../../go/pkg/mod/github.com/dgraph-io/[email protected]/protos/pb/pb.pb.go:7146:29: m.Kv[iNdEx].MarshalToSizedBuffer undefined (type *pb.KV has no field or method MarshalToSizedBuffer)
../../../go/pkg/mod/github.com/dgraph-io/[email protected]/protos/pb/pb.pb.go:7209:29: m.Kv[iNdEx].MarshalToSizedBuffer undefined (type *pb.KV has no field or method MarshalToSizedBuffer)

And I definitely have the newest version, as proved in my protos/Makefile being:
--gofast_out=plugins=grpc,Mapi.proto=github.com/dgraph-io/dgo/v2/protos/api:pb \ pb.proto

Any ideas?

[mangalaman93]

Could you check if you had the protos/pb/pb.go file unmodified? We have seen this issue before and it happens when protos/pb/pb.go is generated using an old version of go-protobuf.

[dihmeetree]

I see api "github.com/dgraph-io/dgo/v2/protos/api" in the /pb/pb.go file.. does that mean it's updated?

[mangalaman93]

Check whether the file that you have locally is same as the on in master branch.

[dihmeetree]

I've confirmed that my pb/pb.pb.go file is the same that's on the master branch @mangalaman93 Can you verify for me once again on your end.. and see if you can replicate my issue from a fresh install of Dgraph?

@mangalaman93 @adg

dgraph/protos/Makefile

Line 19 in 3933ad1

PROTO_PATH := ${PROTO_PATH}:${GOPATH}/src/github.com/dgraph-io/dgo/protos

Should this be PROTO_PATH := ${PROTO_PATH}:${GOPATH}/src/github.com/dgraph-io/dgo/v2/protos instead?

[mangalaman93]

I think we assume that GOPATH is defined, we need to fix this. I think @adg has already created GitHub issues for this. May be, it is using dgo in GOPATH that has older version. I will look into it when I get a chance.

[dihmeetree]

Thank you @mangalaman93 Hope we can get this fixed soon.. really want to start using Go modules with Dgraph soon!
