No errors or warnings when a topic does not exist and auto-create is off

[skandragon]

./rdkafka_example -b "broker-01:9092" -t flarg -p 0

My application also behaves the same way. Ideally, an error should be presented in some way to indicate this configuration is bogus.

Good point.
This will be propagated asynchronously, meaning:

• consumer: returns rkmessage->err with UNKNOWN_TOPIC
• producer: if produce() is called before internal metadata fetch is complete: dr_cb with err==UNKNOWN_TOPIC
• producer: if produce() is called after internal metadata fetch is complete: will fail immediately and return err==UNKNOWN_TOPIC

[skandragon]

Is that how it happens now, or how it will happen with a fix?

[edenhill]

This is how it will happen very soon.

[edenhill]

Or well, the producer behaviour is already like this, only the consumer needs adjusting.

[edenhill]

There, that should do it. Please verify on your end too.
