[issue23638] shutil.copytree makedirs exception

2015-03-11 Thread Martin Panter 

Martin Panter added the comment:

In case it’s not clear to others, the first bit of code is from the 
shutil.copytree() implementation at Lib/shutil.py:303.

The documentation currently says “The destination directory . . . must not 
already exist”. Yuriy seems to be proposing to make copytree() use the existing 
destination directory, and only create it if it does not already exist. Perhaps 
you might be interested in Issue 20849, which proposes passing the 
os.makedirs(exist_ok=...) flag through, which would allow this functionality in 
a backwards-compatible way.

[issue23638] shutil.copytree makedirs exception

2015-03-11 Thread yuriy_levchenko 

New submission from yuriy_levchenko:

We have a code:
names = os.listdir(src)
if ignore is not None:
ignored_names = ignore(src, names)
else:
ignored_names = set()

os.makedirs(dst)

errors = []

But if I had created this folder. I have exception.

Maybe add if?

if os.path.isdir(dst) is False:
os.makedirs(dst)
pass
