I worked at Rockmelt from 2009 till it was acquired by Yahoo. You've never heard of it, but we had a browser built on-top of Chromium that had built-in integration with Facebook, Twitter, Posterous, RSS feeds, everything social of the day: https://imag.malavida.com/mvimgbig/download-fs/rockmelt-8383-1.jpg https://imag.malavida.com/mvimgbig/download-fs/rockmelt-8383... I was our build/release engineer. One of my jobs was keeping our code rebased on-top of Chromium. It wasn't terribly painful but I could always tell when a new engineer joined Chromium because they'd inevitably rewrite some major component and there'd go my day porting our code onto the rewrite. (I did more than just resolve merge conflicts. I also took a first pass at updating our code before handing it off to the rest of the team.) We were using git from the beginning. Chromium was using svn then, but Google had an official git-svn mirror and I worked from that. It's been a while, but I recall that I switched us from working off the tip-of-trunk to working off of release branches. That became feasible when Chromium switched to its more frequent release schedule (2 weeks I think?).
