Every other year or so, this topic comes up on webkit-dev, and the outcome is always the same. We need a monotonically increasing revision number to track down perf regressions, etc... yet nobody has put the time & effort to create a solution with Git. I stay firmly opposed to making the Subversion-to-Git transition until such a solution is devised and implemented in various tools we use. And no, we can't use git-bisect because performance tests take anywhere from 30min to an hour, and we may need ~8 runs to detect a statistically significant difference of 1% or less, meaning that even deciding whether a given perf regression exists between revision X and Y might take ~8 hours. I'm increasingly frustrated that people keep bringing this topic up without ever resolving the issues that have been raised in the past. Keep bringing up the same topic without presenting a solution to the problems that have been raised in the past 8 years or so of the discussion is simply unproductive. - R. Niwa
