I’m stuck on stage 11 of replication in the redis challenge. As far as I can tell things should be operating as expected but I can’t tell what about the behavior isn’t meeting this step’s expectations. Here are my logs: [your_program] command: Set("baz", "789", None) [replication-11] …

@brittlewis12 Okay, think I’ve got an answer here! Was about to go to bed and realized that there could be a conflict between the write & read parts since they use the same lock, and that turned out to be it: [Screenshot 2024-04-06 at 02.02.41] Ensuring that the loop doesn’t loop again (i.e. loc…

Ahh thank you so much Paul! I was already mulling over moving replication to use channels, but I’d have been a bit dissatisfied without understanding why that will resolve it. Thanks again!
