For all the "big" Google projects they use a proprietary system called piper. I think all their open-source stuff (Angular, GoLang, Android) uses git (and sometimes Gerrit). Although given Google's scale, I'm sure there's some teams/projects that use Mercurial.

Go started on Mercurial and then eventually moved into Git.

  And they like neither. They really want a versioned filesystem.

    That's interesting. Do you have more details / refs?

      I understand this was private communication from Rob and Russ.

In fact, developers are allowed to use whichever VCS tool they want on their local machine (or on the online coding in the cloud CitC environment). Some opt to use hg. The canonical repo is in piper though, so the hg commits or git commits get converted before they land.

Gerrit is a review server that uses git. In fact, Gerrit now stores the majority of information in git itself for all the information it uses. So for Google external projects, they use git. > Although given Google's scale, I'm sure there's some teams/projects that use Mercurial. I doubt it. Their tooling is probably pretty specific, and now that code.google.com has shut down, they probably don't have any review servers that support it.

  > Gerrit is a review server that uses git Yup! I use Gerrit at my company and share Administration duties with our Devops team. I know Android uses Gerrit I just wasn't sure if Angular and co. did which is why I worded it a bit more vaguely.

  Yes and no. The answer is actually quite complicated... and I have no idea if I'm allowed to talk about it publically or not.

    Then don't waste peoples time with vacuous comments.

      Ironic reply. Sincere apologies if you can't derive any information from my comment, but that doesn't mean there isn't any there.

        The only information is “google employs me”.
