First I find out the first commit that is in 5.7 that isn’t in 5.6 (using bzr missing) and then look at the authors of all of those commits. Measuring the number of commits is a really<\/strong> poor metric as it does not measure the complexity of the code committed, and if your workflow is to revise a patchset before committing, you get much fewer commits than if you commit 10 times a day.<\/p>\n

There are a good number of people who are committing a lot of code to the latest MySQL development tree. (Sorry for the annoying layout of “count. number-of-commits name”)<\/p>\n

        There’s also a good number with fewer than 10 (31 names actually), which is encouraging as it means that this means it’s likely people who are not involved every day in development of new code (maybe QA, build etc) which probably means that (at least internally) contributing code isn’t really a big problem (and as I’ve shown previously, the barriers to external contributions between Oracle MySQL and MariaDB appear to result in roughly the same amount of code from people outside those companies).<\/p>\n

        There are 125 names here in total, with 19 having over 100 commits, 22 with 50-100 commits, another 53 with 10-50 commits and 31 with <10. So it’s possible to say that there are at least 125 people at Oracle working on MySQL – and I know there are awesome people who are missing from this list as their work doesn’t result in committing code directly to the tree.<\/p>\n","protected":false},"excerpt":{"rendered":"
