quintans opened a new issue #328:
URL: https://github.com/apache/pulsar-client-go/issues/328
#### Expected behavior
`Reader.HasNext()` should return true when when reading last message
inclusive.
#### Actual behavior
`Reader.HasNext()` returns false.
#### Steps to reproduce
```go
package main
import (
"context"
"fmt"
"testing"
"github.com/apache/pulsar-client-go/pulsar"
"github.com/stretchr/testify/assert"
)
const (
lookupURL = "pulsar://localhost:6650"
topic = "persistent://public/default/test"
)
func TestReaderLatestInclusiveHasNext(t *testing.T) {
client, err := pulsar.NewClient(pulsar.ClientOptions{
URL: lookupURL,
})
assert.Nil(t, err)
defer client.Close()
ctx := context.Background()
// create producer
producer, err := client.CreateProducer(pulsar.ProducerOptions{
Topic: topic,
DisableBatching: true,
})
assert.Nil(t, err)
defer producer.Close()
// send 10 messages
var lastMsgID pulsar.MessageID
for i := 0; i < 10; i++ {
lastMsgID, err = producer.Send(ctx, &pulsar.ProducerMessage{
Payload: []byte(fmt.Sprintf("hello-%d", i)),
})
assert.NoError(t, err)
assert.NotNil(t, lastMsgID)
}
// create reader on the last message (inclusive)
reader, err := client.CreateReader(pulsar.ReaderOptions{
Topic: topic,
StartMessageID: pulsar.LatestMessageID(),
StartMessageIDInclusive: true,
})
assert.Nil(t, err)
defer reader.Close()
var msgID pulsar.MessageID
if reader.HasNext() {
msg, err := reader.Next(context.Background())
assert.NoError(t, err)
assert.Equal(t, []byte("hello-10"), msg.Payload())
msgID = msg.ID()
}
assert.Equal(t, lastMsgID, msgID)
}
```
