Public bug reported:
Binary package hint: coreutils
GNU coreutils cp(1) behaves incorrectly if the user tries to copy a
directory recursively. It (rightly) prints an error message, BUT copies
the directory anyway, at least one level deep. To demonstrate:
| [EMAIL PROTECTED]:~$ uname -a
| Linux tranquility 2.6.22-14-386 #1 Sun Oct 14 22:36:54 GMT 2007 i686 GNU/Linux
We're using Ubuntu "Gutsy Gibbon" 7.10.
| [EMAIL PROTECTED]:~$ mkdir foo
| [EMAIL PROTECTED]:~$ touch foo/testfile
We're creating a folder containing one file.
| [EMAIL PROTECTED]:~$ cp -r foo foo
| cp: cannot copy a directory, `foo', into itself, `foo/foo'
We're trying to copy that folde into itself. cp(1) prints an error (as
it should). However, ls -al (ll) shows that despite the error message,
foo and the testfile it contains have nevertheless been copied into foo:
| [EMAIL PROTECTED]:~$ ll foo
| total 12
| drwxr-xr-x 3 ropers ropers 4096 2007-10-19 22:57 ./
| drwxr-xr-x 85 ropers ropers 4096 2007-10-19 22:56 ../
| drwxr-xr-x 2 ropers ropers 4096 2007-10-19 22:57 foo/
| -rw-r--r-- 1 ropers ropers 0 2007-10-19 22:56 testfile
| [EMAIL PROTECTED]:~$ ll foo/foo
| total 8
| drwxr-xr-x 2 ropers ropers 4096 2007-10-19 22:57 ./
| drwxr-xr-x 3 ropers ropers 4096 2007-10-19 22:57 ../
| -rw-r--r-- 1 ropers ropers 0 2007-10-19 22:57 testfile
| [EMAIL PROTECTED]:~$
This should not happen. When asked to copy a directory recursively,
cp(1) should print an error and not perform any copy operation at all.
