New submission from Jeremy Pinto <jerp...@gmail.com>:
Issue: If you try to copy a file to a directory that doesn't exist using
shutil.copy, a IsADirectory error is raised saying the directory exists.
This issue is actually caused when `open(not_a_dir, 'wb') is called on a
non-existing dir.
Expected behaviour: Should instead raise NotADirectoryError
-----------------------------
Steps to reproduce:
[nav] In [1]: import os
...: from pathlib import Path
...: from shutil import copy
...:
...: tmp_file = '/tmp/some_file.txt'
...: Path(tmp_file).touch()
...: nonexistent_dir = 'not_a_dir/'
...: assert not os.path.exists(nonexistent_dir)
...: copy(tmp_file, nonexistent_dir)
---------------------------------------------------------------------------
IsADirectoryError Traceback (most recent call last)
<ipython-input-2-b0e0ec4f4875> in <module>
7 nonexistent_dir = 'not_a_dir/'
8 assert not os.path.exists(nonexistent_dir)
----> 9 copy(tmp_file, nonexistent_dir)
~/miniconda3/lib/python3.7/shutil.py in copy(src, dst, follow_symlinks)
243 if os.path.isdir(dst):
244 dst = os.path.join(dst, os.path.basename(src))
--> 245 copyfile(src, dst, follow_symlinks=follow_symlinks)
246 copymode(src, dst, follow_symlinks=follow_symlinks)
247 return dst
~/miniconda3/lib/python3.7/shutil.py in copyfile(src, dst, follow_symlinks)
119 else:
120 with open(src, 'rb') as fsrc:
--> 121 with open(dst, 'wb') as fdst:
122 copyfileobj(fsrc, fdst)
123 return dst
IsADirectoryError: [Errno 21] Is a directory: 'not_a_dir/'
