Merging

File renaming problems

If, while merging, you encounter the following scary message: 

  warning: too many files, skipping inexact rename detection

You'll get a whole lot of merge conflicts which one would imagine git could have take care of. The problem, at least in my case, is that because detecting file name changes is currently an O(n^2) operation for git, which may take a long time--especially when you take into account the number of files in our repository. As such, git defines an upper limit on the search, so that it will stop after m iterations. This limit defaults to 1, but can be set by changing the value of diff.renamelimit to something higher. A value of 400, in my case, seemed to do the trick.
