Recently there has been a lot of discussion around the development growing pains in nova. Instead of guessing about how bad some of the issues are, I tried to answer a few questions that may help us better understand the issues.
Q: How many revisions does it take to merge a patch? Average: 6.76 revisions median: 4.0 revisions Q: How many rechecks/verifies does it take to merge a patch (ignoring rechecks where the same job failed before and after)? Average: 0.749 rechecks per patch revision median: 0.4285 rechecks per patch revision For comparison here are the same results for tempest, which has a lot more gating tests: Average: 1.01591525738 median: 0.6 Q: How long does it take for a patch to get approved? Average: 28 days median: 11 days Q: How long does it take for a patch to get approved that touches 'nova/virt/'? Average: 34 days median: 18 days When looking at these numbers two things stick out out: * We successfully use recheck an awful lot. More then I expected * Patches that touch 'nova/virt' take about 20% more time to land or about 6 days. While that is definitely a difference, its smaller then I expected Dataset: last 800 patches in nova Code: https://github.com/jogo/gerrit-fun
