Google Is 2B Lines of Code, All in One Place

How do the monolithic repository companies handle dependencies on external source code?

Are libraries and large projects e.g. RDBMS generally vendored/forked into the monolithic repositories, regardless of whether the initial intent is to make significant changes?

There's typically a subdirectory called third_party, with subdirectories for each vendor, product and version. If the team is smart, they will also enact a rule saying "only one version". If you're really, really smart, local changes are kept as a set of patches, keeping them separate from the imported tar file.

So, for source deliveries:

  third_party/apache/httpd/2.4/release.tgz
                              /patch.tgz
                              /Makefile (or other config)
  third_party/apache/httpd/2.2/release.tgz
                             /patch.tgz                             
  ...

For example, here is Chromium's third_party directory:
