I’m stuck on this stage . So, I received the command as: *3\r\n$4\r\nWAIT\r\n$1\r\n3\r\n$3\r\n500 which expects a timeout of 500 ms. However, it’s getting a timeout in 500 ms, resulting in 0 responses during that time, causing the test to fail. I tried adding a readTimeout for the duration, but it…

it seems to be in stage 17 when there is not previous write command you don’t actually need to send the ack command, just return the number of the connected replicas. i don’t know if the the intention of the challenge of not. but it seems to work in my code.

Yes, that was the case. Spent at least a week for this! Thank you :slightly_smiling_face:

Yep! We’ll make this more clear when we work on instructions for this stage, sorry it’s taken so long

Does this not make stage 17 incompatible with stage 18? My code passes stage 18 when I default to returning the number of acknowledged replicas on timeout, but it only passes stage 17 if I default to returning the total connected replicas. Can you update the stage 17 test so that the replicas will r…

Ah, I can see how this’d be confusing. Here’s what an actual Redis server does (we test against official Redis binaries 100s of times on each release to make sure our tester isn’t faulty): A master keeps track of the current replication offset, and the replication offset of every connected replic…

That was very helpful, thanks! I definitely overlooked that when reading the docs. I got it working now with a small change.
