Don't you think it would be better to print it once in set_flow_def ?

Actually the check is wrong to begin with, I think the intention is to make sure the sum(uref_channels) = sum(flow_def_channels)

Since I am working on the pipe I took a quick look at this. AFAICS if you do it in set_flow_def for the subpipes it will print one message for each input until the sum equals the output flow_def, then nothing when equal, then again when greater. Maybe it is supposed to check that the input urefs match what the input flow_defs say and print a message when they are different indicating some error. I'm not sure myself so I have just silenced it while I am testing. |
