Subject: git status / git diff -C not detecting file copy
Message-ID: <CAJxwDJzzNV77cTP4nbzgCvFjjqp3C4X8d3j6uwhYvK4+g4r1YQ@mail.gmail.com>

Hi,

The documentation for git status at http://git-scm.com/docs/git-status
implies that it should be able to detect both renames and copies (with
the R and C states). The command git diff -C should do it as well.

However I can't get either to detect copies in this simple test case -
what is happening?


mkdir test
cd test/
git init
echo 'Hello World!' > hello.txt
echo 'Goodbye World!' > goodbye.txt
git add -A
git commit -m "Initial commit"

cp hello.txt copied.txt
mv goodbye.txt moved.txt
git add -A

$ git status --short
A  copied.txt  <------------ NO COPY DETECTED
R  goodbye.txt -> moved.txt

$ git diff -M -C --summary --cached
 create mode 100644 copied.txt  <------------ NO COPY DETECTED
 rename goodbye.txt => moved.txt (100%)

$ git commit -m Test
$ git diff -M -C --summary HEAD~
  create mode 100644 copied.txt  <------------ NO COPY DETECTED
  rename goodbye.txt => moved.txt (100%)
