Mercurial

Using Mercurial with a SVN repository in a production environment without any drama

Why would I want to use Mercurial or any other DVCS client with a Subversion repository?

  • It lets us keep SVN as our central repository
  • Some team members prefer not to use a DVCS for whatever reason so it lets them carry on using SVN without interruption.
  • It allows me to work and commit changes (but not push!), search history and switch between branches completely disconnected. I can continue to work during network outages or while traveling when I don’t have connectivity.
  • You get full, fast history search.
  • Switching between branches is easy and fast.
  • Any automated processes which use SVN (i.e. automated builds and deployments) can continue to operate while everyone moves to DVCS.
  • It’s much easier to perform merges than regular SVN (via export/import patch queues – which I detail later)
