Google has everything in one Perforce repo? You mean the search engine, do you?

I agree btw, the Github mindset is the best one. Create for every project a new repo and connect them with build tools. But why not hire 100 SOA-Consultants, they have enough money now.

No, literally the entire codebase for all of their products is in one Perforce repo. Ashish Kumar, manager of the Engineering Tools team, mentions it in this presentation: http://www.infoq.com/presentations/Development-at-Google

Very interesting, thank you.

The kernel? Android? Some other spooky stuff involving the pest control guy who's holding a big rubber mallet when you fail a unit test?

Are you sure about that?

Kernel/Android/Chrome/basically anything open-source is different. If the code is going to be open-sourced, it can't have dependencies on proprietary code anyway.

Right, so "literally the entire codebase for all their products" is incorrect. Thanks.

The open-source stuff is a rounding error. Think about all the Google products; Search, Google+, Gmail, Groups, Translate, Maps, Docs, Calendar, Checkout, Wallet, Voice, ... those are all in one repository. (Not to mention all the libraries and internal tools; those are all in there too.)

To be fair, Android and Chrome are pretty huge projects. I know the numbers (though I don't think I can share them outside of Google), and while they're nowhere close to being a big part of the total, they're also big enough to not be considered a rounding error.

Ah,rachelbythebay, you caught him for being "technically incorrect". Which, depending on how you look at it, is either the best or worst kind of correctness.
