shutils.move lose files !

[Shagshag]

hello,

here is a behavior that i discover by error :

in the following example directory 'stupid' is lost such as eventual
files and directory contained in it (for example 'atest.txt') while i
would have prefer to be warned or at least nothing to happen.

is it a bug ?

Re: shutils.move lose files !

The same happens on Linux:
$ mkdir a; python2.3 -c 'import shutil; shutil.move("a" , "a/c")'
$ ls -l a
ls: a: No such file or directory

Unix mv has a test that prevents this:
$ mkdir a; mv a a/c
mv: cannot move `a' to a subdirectory of itself, `a/c'

I've created a sourceforge bug report about this. Visit here:

If it'isnt it looks like one a lot ;)

-----
Doing the equivalent in bash i get :
$> mv tmp-dir/ tmp-dir/tmp-dir
mv: cannot move `tmp-dir/' to a subdirectory of itself, `tmp-dir/tmp-dir'

Leaning me more toward the bug hypothesis :)

But it's not the same thing: you are renaming a file, leaving it in its
original directory. The original poster tried to move the directory into
a subdirectory of itself.
