I’m stuck on stage 13. I’ve tried so I’ve set up two go routines to handle connections from clients and masters (for replicas). Issue is whenever I run the test, only some of the SET commands will propagate to the replicas. usually its second or third. but never all three. Not sure whats going on. …

[image] Maniktherana: Invalid request, expected array This part of the logs seems relevant - @Maniktherana could you try logging out what you received too, that isn’t an array? I think that’ll help shed some light on what’s going on.

updated logs: [replication-13] Sending RDB file...[replication-13] master: Sent bytes: "$8 - Pastebin.com These are logs from when the replica is receving the RDB file. I’m not explicitly accepting the RDB file and its not quite an array, hence why its there. You can refer to line 40 in my code: Gi…

@Maniktherana my best guess is that one of the commands is getting swallowed somewhere in parsing - could you confirm this by adding a log here? tmp/app/resp.go at 3fdc659ea21dec3891baf03acdf1776348371169 · Maniktherana/tmp · GitHub (soon after reading bytes from the reader).

@rohitpaulk added the log here: func (r *Resp) readLine() (line []byte, n int, err error) { for { b, err := r.reader.ReadByte() if err != nil { return nil, 0, err } + fmt.Printf("%c", b) n += 1 line = append(line, b) if len(line) >= 2 && line[len(line)-2] == '\r' { break } }…

@Maniktherana something seems weird with the logging here, I only see numbers printed and no content? More bytes are certainly being received since I see the parsed version in “slave received”. Could you try logging in such a way that every single byte received is logged out? Without that it’s hard …
