Re: Proposal: tell git a file has been renamed

Telling Git is the easy part. How to make it honor what it was told earlier is harder.

I recall that there was an idea about recording similarity index between two blobs precomputed so that the same pair of blobs do not have to be computed over and over again, when you do "git log -M"?

An obvious way to implement this "I know HEAD^:path1 and HEAD:path2 are similar enough that they deserve to be called a rename" can be to invalidate and then contaminate such a similarity cache with end-user supplied data.
