In ccminer there is a "yes!" - accepted share, "nooooo" - rejected share and "yay!!!" which is share that found a block.
I believe that it this come from pooler's original cpuminer.
That's interesting. It definitely isn't implemented that way in cpuminer and I don't recall seeing any code regarding
block finder. I will take a look at Pooler. If he has impmeneted it that way it's worth considering.
Edit: I just looked at he latest Pooler code and he still uses yay!!!/boooo for accepted/rejected shares with no indication
of finding a block. It's an interesting idea but I don't see anywhere that the pool communicates that info to the miner.
