Why can't Go find these source files?

Asked 2022-Feb-04 at 19:56

I'm trying to compile kaniko on a raspberry pi.

I don't program in golang, but I was able to compile kaniko successfully a few weeks ago on the same raspberry pi, and even wrote myself a guide of the steps to follow, but now, following the same steps, something is broken.

kaiko requires go, but a more recent version of go then found in the raspberry pi repos, so I download and install go from scratch. go requires go to compile, so I first install it (an older version) from the repos, and then remove it after it's done compiling a more recent version of itself:

Based on the comments, my suggestion is to add $HOME/go/bin to the path and use the default GOPATH.

Go mod depends on the bin directory inside the GOPATH. It installs new packages there. The go binary itself can actually reside somewhere else. If you follow these install instruction https://go.dev/doc/install, go itself will actually be in /usr/local/go but the GOPATH is still $HOME/go.

I would also recommend, not involving apt in this at all. This looks like trouble in the form of conflicts with different installations.

The argument to List().Append() is supposed to be a protoreflect.Value that carries appropriate type information.

To append a typed protobuf nil item, you can use protoreflect.ValueOf in this way:

Yeah, the backend doesn't decode proto Timestamp messages properly.

Quickest resolution answer: send int64 type, populate as epoch microseconds.

Ok I solved the issue.

I had installed protoc via snap and the stable channel had version 3.11.4

QUESTION

How to extract field from protobuf message without schema

Asked 2021-Apr-15 at 09:47

According to this issue, the protoreflect package provides APIs for accessing the "unknown fields" of protobuf messages, but I don't see any way to use it if there isn't any existing schema. Basically, I want to perform a "weak decode", similar to what the JSON unmarshaller does if the output is of type map[string]interface{}.

The example from the documentation looks like this:

ANSWER

Answered 2021-Apr-15 at 01:15

I was able to achieve this using the low level protowire package. Here is a full example, where I extract two fields of type uint64 (which happen to be assigned field numbers 4 and 5 in the original schema):

Importing proto files from different package causes 'missing method protoreflect'

Asked 2021-Jan-29 at 22:33

I am new to Go and Protobufs hence this might be a very noob question. Sorry for that.

I have several packages in my go project and I wanted to create a seperate package which contains all my .proto (also .pb.go) files and then I can import those proto files in any other packages to better manage all my proto files.

But when I moved my proto files to a seperate package called "prototemps" and imported "prototemps" in another package called "reader". In reader.go, I do:

The error message says that the variable sensorData is missing a method ProtoReflect. Checking the generated file, this is correct. There is no such method on the Sensor type.

It seems to me you are having issues with different versions of Go's protobuf. Make sure you are using the same version for generating the *.pb.go files as you are using for marshalling / unmarshalling.

There are different packages in the Go world right now that are not compatible as there are breaking API changes: https://blog.golang.org/protobuf-apiv2

If you are starting with protobuf, I'd definitely try to go with the new package. Make sure any introduction you are following uses the package you are using.

gRPC GO Single Generic Service Handler

Asked 2021-Jan-13 at 09:29

I have used protoreflect to write http-to-gRPC-gateway. But I don't see any easy option to do the reverse - gRPC-to-HTTP-gateway. One of the idea is to expose GRPC to outside but use a custom gateway to invoke internal microservices via MessageQ to avoid loadbalancing, discovery service and may be convert GRPC streaming durable or use reflection to invoke method instead of using generated server stub

Below is what I got so far

The file is valid; see the comments from dsnet in response to this issue:

The only reason the newly generated .pb.go files depend on the deprecated proto package is to enforce a weak dependency on a sufficiently new version of the legacy package. This is necessary because not everyone is using Go modules such that the Go toolchain would enforce this dependency constraint. I wasn't fond of adding it, but I think it's probably necessary to keep at least for a few months.
