When trying to update my go deps, I get the following:

# contrib.go.opencensus.io/exporter/jaeger
/go/pkg/mod/contrib.go.opencensus.io/exporter/[email protected]/agent.go:76:10: a.client.SeqId undefined (type *agent.AgentClient has no field or method SeqId)
/go/pkg/mod/contrib.go.opencensus.io/exporter/[email protected]/agent.go:77:30: not enough arguments in call to a.client.EmitBatch
        have (*jaeger.Batch)
        want (context.Context, *jaeger.Batch)
/go/pkg/mod/contrib.go.opencensus.io/exporter/[email protected]/jaeger.go:361:21: not enough arguments in call to obj.Write
        have (*thrift.TBinaryProtocol)
        want (context.Context, thrift.TProtocol)

I have to add the following to keep things happy, but I guess there was a breaking change in the v2.29 update?

replace github.com/uber/jaeger-client-go v2.29.1+incompatible => github.com/uber/jaeger-client-go v2.28.0+incompatible

Additional context

This library is the only one in our binary that usese google.golang.org/api/support/bundler.

This is how we have configured it

       exporter, err := jaeger.NewExporter(jaeger.Options{
		CollectorEndpoint: endpoint,
		Process: jaeger.Process{
			ServiceName: serviceName,
			Tags: []jaeger.Tag{
				jaeger.StringTag("process_name", processName),
				jaeger.StringTag("version", version.GetVersion()),
			},
		},
		BufferMaxCount: 256 * 1e6, // 256Mb
		OnError: func(err error) {
			log.WithError(err).Error("Failed to process span")
		},
	})

Security Policy Violation
Security policy not enabled.
A SECURITY.md file can give users information about what constitutes a vulnerability and how to report one securely so that information about a bug is not publicly visible. Examples of secure reporting methods include using an issue tracker with private issue support, or encrypted email with a published key.

To fix this, add a SECURITY.md file that explains how to handle vulnerabilities found in your repository. Go to https://github.com/census-ecosystem/opencensus-go-exporter-jaeger/security/policy to enable.

For more information, see https://docs.github.com/en/code-security/getting-started/adding-a-security-policy-to-your-repository.

This issue will auto resolve when the policy is in compliance.

problem

my code is come from quickstart
I replace openzipkin with jaeger:

package main

import (
	"bytes"
	"context"
	"encoding/binary"
	"fmt"
	"log"
	"time"

	"contrib.go.opencensus.io/exporter/jaeger"
	"go.opencensus.io/trace"
)

func main() {
	//// 1. Configure exporter to export traces to Zipkin.
	//localEndpoint, err := openzipkin.NewEndpoint("go-quickstart", "192.168.1.5:5454")
	//if err != nil {
	//	log.Fatalf("Failed to create the local zipkinEndpoint: %v", err)
	//}
	//reporter := zipkinHTTP.NewReporter("http://localhost:9411/api/v2/spans")
	//ze := zipkin.NewExporter(reporter, localEndpoint)
	//trace.RegisterExporter(ze)
	//
	//// 2. Configure 100% sample rate, otherwise, few traces will be sampled.
	//trace.ApplyConfig(trace.Config{DefaultSampler: trace.AlwaysSample()})

	agentEndpointURI := "http://localhost:6831"
	collectorEndpointURI := "http://localhost/api/traces"

	je, err := jaeger.NewExporter(jaeger.Options{
		AgentEndpoint:     agentEndpointURI,
		CollectorEndpoint: collectorEndpointURI,
		ServiceName:       "demo",
	})
	if err != nil {
		log.Fatalf("Failed to create the Jaeger exporter: %v", err)
	}

	// 3. Create a span with the background context, making this the parent span.
	// A span must be closed.
	ctx, span := trace.StartSpan(context.Background(), "main")
	// 5b. Make the span close at the end of this function.
	defer span.End()

	for i := 0; i < 10; i++ {
		doWork(ctx)
	}
}

func doWork(ctx context.Context) {
	// 4. Start a child span. This will be a child span because we've passed
	// the parent span's ctx.
	_, span := trace.StartSpan(ctx, "doWork")
	// 5a. Make the span close at the end of this function.
	defer span.End()

	fmt.Println("doing busy work")
	time.Sleep(80 * time.Millisecond)
	buf := bytes.NewBuffer([]byte{0xFF, 0x00, 0x00, 0x00})
	num, err := binary.ReadVarint(buf)
	if err != nil {
		// 6. Set status upon error
		span.SetStatus(trace.Status{
			Code:    trace.StatusCodeUnknown,
			Message: err.Error(),
		})
	}

	// 7. Annotate our span to capture metadata about our operation
	span.Annotate([]trace.Attribute{
		trace.Int64Attribute("bytes to int", num),
	}, "Invoking doWork")
	time.Sleep(20 * time.Millisecond)
}

when I run my program and access port 16686 of the Jaeger UI,I can't find my service registered in jaeger on the Jaeger UI

solution

just replace "time.Sleep(20 * time.Millisecond)" with "time.Sleep(time.Second)"

why is that?

// On receiving side
span.AddMessageReceiveEvent(id, n, n)

What did you expect to see?

Messages linked in jaeger

What did you see instead?

Nothing.

Additional context

See how stackdriver exports these events: https://github.com/census-ecosystem/opencensus-go-exporter-stackdriver/blob/4351271b777d160d27010a22de3e41fd07335556/trace_proto.go#L121

NB: Before opening a feature request against this repo, consider whether the feature should/could be implemented in exporter libraries in other languages. If so, please open an issue on opencensus-specs first.

Is your feature request related to a problem? Please describe.
For my application I need to connect with Jaeger traces that are incoming. Therefore I need to do a propagation with the correct header and the Jaeger header format.

Describe the solution you'd like
My solution is to do it in the same way as the stackdriver exporter does it. https://github.com/census-ecosystem/opencensus-go-exporter-stackdriver/tree/master/propagation

The stackdriver exporter implements the HttpFormat of opentracing and returns a SpanContext with the remote tracingID.

Describe alternatives you've considered
I have not found any alternative with opencensus in order to connect existing traces of a remote.

Additional context
I will open a pull request which successfully works with a traefik setup adding a trace to the backend. See screenshot below:

Can you please release new version (0.2.0) with latest code?
Current latest release doesn't contain jaeger propagator.
