I use gerrit. I first created a copy of a FooService -> to BarService, changed it and commited it. Later I Removed FooService, commited it. FooService is visible in gerrit as deleted, BarService as Added. How can I fix it, to be visible as renamed FooService->BarService, before I merge my change?
Probably you made too many changes in the original file so Gerrit (Git) is unable to recognize it. You can divide your change into two commits (changes in Gerrit): first, rename the file, and after that make the changes.
