The BK openlogging tree, which has all changesets ever made by anyone in the Linux kernel, was getting big. Really big. The nodes in the graph have internal "serial numbers" which are currently 16 bits, i.e., there can't be more than 64K nodes in the graph. I sent mail to some of my engineers this morning saying "hey, I suspect the Linux openlogging tree is about overflow, we need to go to 32 bit ser_t's." I had no idea how close we were, I just knew it was a problem we needed to solve. I just got mail from one of the team which reads: "With 199 serials shy of overflowing , the 32 bit version is now installed". What that means is that in about a year, you've managed to create 65,337 changesets. That's 179 per day, 7.4/hour, 24x7. You guys are busy. To put that in perspective, the most active project on sourceforge today, Gaim, has 805 commits to its changelog. Over 3.5 years. That means you are changing your source base 284x more often than they are. And that's just the BK users, that doesn't count the people not using BK, which are a substantial fraction. No matter how you slice it, it is pretty amazing rate of change. If change is good, you guys rock, I've never seen anything like it. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm
