Tracking SVN changes through multiple merges

At work we use a branching strategy where all changes start off in a development branch, then subsequently make their way through one or more integration branches, and finally end up in a release branch.

Occasionally (more oft开发者_如何学编程en than I'd like) I find myself needing to figure out where a particular change originated (which development branch). In this case I have to spend a considerable amount of time playing detective to trace a change backwards through 2-3 merges.

Am I missing an easy way to do this?


With subversion 1.5 and higher a few commands have a -g option to use the megeinfo data to construct a more complete view of history. This does require you to have used subversion 1.5 or higher on the server and done all the merging with svn 1.5 or higher.

  • svn log -g
  • svn blame -g

A quick test shows that this doesn't work flawlessly (I have duplicate history entries on a fairly simple test case) but it may be good enough for what you need.
