Hence I don't understand how the build-bots would be aware of this detail. Unless you explicitly state what the dependencies are, how would the build-bots know? Perhaps there's some logic built-in somewhere that I don't know about? > there is no real need to be overreactive here and in this particular > case it's better to react to real problems once they show up (we already > did that by fixing build breakage caused by a CLK API problem found by > bot in v3). Does it sound like a good argument to you? ACK? No. This strikes me as a strange argument. I'm pointing out a potential source of problems and you just brush it aside claiming that it's not true, or even if it was true that we'll see eventually and we can fix it up when there's an actual problem. Why would you want to have to fix things up if you can avoid breakage in the first place by being a little proactive? Thierry
