Abort trap: 6 Assertion failed: (r == 0), function rwlock_wrlock, file tinycthread_extra.c

[nijikon]

I run into this issue when running specs locally. I checked on 1.2.2-RC1, 1.2.0 and 1.1.0. Any ideas?

balrog:rdkafka-ruby n$ be rspec --profile 20 ./spec/rdkafka/consumer_spec.rb

This is the spec that generates the issue. https://github.com/appsignal/rdkafka-ruby/blob/master/spec/rdkafka/consumer_spec.rb#L52-L93

[rgo]

Executing all specs in consumer_spec, I got:

Rdkafka::Consumer
  #subscripe, #unsubscribe and #subscription
    should subscribe, unsubscribe and return the subscription
    should raise an error when subscribing fails
    should raise an error when unsubscribing fails
    should raise an error when fetching the subscription fails
  #pause and #resume
    should raise when not TopicPartitionList
    should raise an error when pausing fails
    should raise an error when resume fails
    subscription
      should pause and then resume
  #seek
    should raise an error when seeking fails
    subscription
Assertion failed: (r == 0), function rwlock_wrlock, file tinycthread_extra.c, line 138.

[Process exited 134]

I added traces to locate the assertion fail and went till: https://github.com/appsignal/rdkafka-ruby/blob/master/spec/rdkafka/consumer_spec.rb#L149

Narrowing the search a little bit more I arrived to: consumer#poll https://github.com/appsignal/rdkafka-ruby/blob/master/lib/rdkafka/consumer.rb#L346

I'll take a deep look into it later.

[rgo]

Sadly, I'm stuck in consumer#poll. No (good) news :(

I think there are some issues on the librdkafka side, but only on Mac. I've been pretty busy with other things, planning to get the dev and testing environment back to a good state again now.

[rgo]

At night, I'll try with librdkafka 1.2.2 that was released yesterday.
I don't have big hopes because we were already using 1.2.2-rc1

[thijsc]

There's an upgrade to 1.2.2 in #98

[thijsc]

Are you still getting this when running #98?

[Adithya-copart]

I remember seeing this error while working on #108 but don't recall the reason exactly.

It should not be reproducible in the specs now.

Update: Same error occurred calling Consumer#store_offset where enable.auto.offset.store is true.

[thijsc]

Are you still seeing this happen on master? A number of related fixes have been merged.

[thijsc]

This has probably been fixed, possibly also by #97. Feel free to reopen though.
