I’m stuck on Redis Replication Stage 18. After receiving the WAIT on the master, I send REPLCONFs to all the replicas. Then I start a thread for every replica, where I try to receive a response from them (within the timeout). In the master’s main thread, it waits for one of the two conditions to fu…

Going to mark this as solved for now since we’ve improved logs, if anyone’s still running into this please share code + logs and we’ll take a look!

Looks like the problem start at 17-th step: [image] Incorrect test for Replication 17 Challenges I am also running into the same issue. Setting debug: true in the config file shows that the test replica does not respond to the getack commands that I send as the connection …

I am not sure if this is related. My stage 17 was passing consistently when I was on it and the recent change by CodeCrafters means the tests are run in reverse order, so it only runs tests for stage 17 when stage 18 passes. My problem is that ~95% of the time, I don’t get enough reponses from the …

We’ll add better logs for this stage that convey when we a replice receives a GETACK (and whether it intends to respond with an ACK or not)

That would be very helpful, thanks! From my implementation, it seems all replicas receive GETACKs but not all of them which intend to reply, reply before their associated receiving thread times out. I was wondering whether it is a guarantee that all the intended replicas will reply before the time…
