Git tagging with Fabric

22 February 2012

Over on codeinthehole.com, David Winterbottom has written up a Fabric function for elegantly handling git tagging when running deployments. Such a function is part of all python deployment scripts used at Tangent Labs - it helps ensure that every build is either tagged or has a build number that helps QA determine where in the release cycle an integration build is.

There are two notable bits of commandlinefu worth noting:

  • The -V flag used with sort is a useful option for sorting version numbers where 1.10 should come after 1.9.4.
  • git describe is a super-useful command for generating a build number without using a tag.  It generates the build number based on the number of commits since the last tagged release.
