test_description='Break and then rename |
|
|
|
We have two very different files, file0 and file1, registered in a tree. |
|
|
|
We update file1 so drastically that it is more similar to file0, and |
|
then remove file0. With -B, changes to file1 should be broken into |
|
separate delete and create, resulting in removal of file0, removal of |
|
original file1 and creation of completely rewritten file1. |
|
|
|
Further, with -B and -M together, these three modifications should |
|
turn into rename-edit of file0 into file1. |
|
|
|
Starting from the same two files in the tree, we swap file0 and file1. |
|
With -B, this should be detected as two complete rewrites, resulting in |
|
four changes in total. |
|
|
|
Further, with -B and -M together, these should turn into two renames. |
