  1.  @RudhinMenon  Then the problem is not that we are working on master instead of a branch. The root cause is that "it takes days to stabilize". 1. What would need to change in your way of working for master to always be stable (without branches)? 2. How would you behave differently if, at any time, anyone can take the latest build from master and deploy it to production? 3. What if "done" meant "running in production, working, making the company money" instead of "coded on a branch, but not really tested nor integrated"? Just some thoughts...

  2. In part. Continuous Integration is a human practice where it is expected that the developers pulls the latest changes and run the unit tests, lint, checkstyle, findbugs, (and component integration tests) before pushing. Those same checks are then run at push, which is called a "commit build" and should give you a high confidence that everything works. In CD there are other kinds of tests and checks downstream that takes different aspects of the entire system into account. As I understand it, the embargo shown here is seldom used. Again, CI is a human practice and a social contract: if the build is not fixed within 10 minutes, anyone can revert the commit that broke it. The key here is to be disciplined and don't break things all the time, and the few times it breaks we do whatever we can to get back to a working state. Shit happens, learn from it and move on. Part of the issue with feature branches is that it optimizes for individual developers working alone in their corner with headphones on. This is a bad thing. Sure, you can use short-lived feature branches if you must; where (in my view) short means a couple of hours. But if most only live 30 minutes to a few hours what's the point of branching in the first place? Look, I'm just an opinionated a-hole that's tired of arguing with people and also thinks that part of the popularity around FB/PR is an amazing feat of social engineering by the tool-vendors that has even the oil and tobacco companies in awe. So I'm just going to give up and drop this Twitter thread by Jez Humble: https://twitter.com/jezhumble/status/982988370942025728

  3. What do you mean by "runs on CI"? Why I ask is because I see this confusion everywhere; where people thinks that CI is a build server and/or "running tests on a branch". Neither are true. They don't need branches to improve anything because they have the practices, experience and discipline to move faster with higher quality without them.
