shohi opened a new issue #288:
URL: https://github.com/apache/pulsar-client-go/issues/288
#### Expected behavior
create the consumer successfully. According to the doc, ReceiverQueueSize
set to `-1` only disables prefetching in consumer.
#### Actual behavior
Panic when creating consumer with the setting.
```
panic: makechan: size out of range
```
Test code
```go
func TestConsumer_NegativeQueueSize(t *testing.T) {
client, err := pulsar.NewClient(pulsar.ClientOptions{
URL: "pulsar://localhost:6650",
})
if err != nil {
t.FailNow()
}
defer client.Close()
consumer, err := client.Subscribe(pulsar.ConsumerOptions{
Topic: "topic",
SubscriptionName: "my-sub",
ReceiverQueueSize: -1,
})
defer func() {
if consumer != nil {
consumer.Close()
}
}()
if err != nil {
t.FailNow()
}
}
```
#### System configuration
**Pulsar version**: 2.5.2
**pulsar-client-go**: latest(861d7af)
