[GitHub] [pulsar-client-go] krvarma opened a new issue #250: SDK crashes on ARM
krvarma opened a new issue #250:
URL: https://github.com/apache/pulsar-client-go/issues/250
#### Expected behavior
pulsar-client-go SDK should work on ARM without any issues
#### Actual behavior
The SDK crashed on ARM-based devices when trying to Subscribe. The crash occurs when we call `client.Subscribe`. The crash occurs at this point on the code.
```
consumer, err := client.Subscribe(pulsar.ConsumerOptions{
Topic: "my-topic",
SubscriptionName: "first-subscription",
Type: pulsar.Exclusive,
})
```
#### Steps to reproduce
Run the following simple consumer go program on ARM-based device (Tested on Raspberry Pi 3 Model B+).
```
package main
import (
"fmt"
"log"
"os"
"context"
"github.com/apache/pulsar-client-go/pulsar"
)
func main() {
client, err := pulsar.NewClient(pulsar.ClientOptions{URL: "pulsar://localhost:6650"})
if err != nil {
log.Fatal(err)
}
defer client.Close()
consumer, err := client.Subscribe(pulsar.ConsumerOptions{
Topic: "my-topic",
SubscriptionName: "first-subscription",
Type: pulsar.Exclusive,
})
if err != nil {
log.Fatal(err)
}
defer consumer.Close()
ctx := context.Background()
// Listen indefinitely on the topic
for {
msg, err := consumer.Receive(ctx)
if err != nil { log.Fatal(err) }
// Do something with the message
fmt.Printf("Message Received: %v\n", string(msg.Payload()))
if err == nil {
// Message processed successfully
consumer.Ack(msg)
} else {
// Failed to process messages
consumer.Nack(msg)
}
}
}
```
