New submission from Rich Jones <miser...@gmail.com>:
If I try to create a symlink which already exists, I get a FileExistsError. In this error message, the explanatory arrow is pointing in the wrong direction. This gave us a big scare in our logs! Example: ``` $ ls HELLO.txt $ python3 Python 3.7.0 (default, Jul 23 2018, 20:22:55) [Clang 9.1.0 (clang-902.0.39.2)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import os >>> os.symlink('HELLO.txt', 'GOODBYE.txt') $ ls -lah * lrwxr-xr-x 1 rjones staff 9B Nov 30 15:36 GOODBYE.txt -> HELLO.txt -rw-r--r-- 1 rjones staff 4B Nov 30 15:34 HELLO.txt $ python3 Python 3.7.0 (default, Jul 23 2018, 20:22:55) [Clang 9.1.0 (clang-902.0.39.2)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import os >>> os.symlink('HELLO.txt', 'GOODBYE.txt') Traceback (most recent call last): File "<stdin>", line 1, in <module> FileExistsError: [Errno 17] File exists: 'HELLO.txt' -> 'GOODBYE.txt' ``` Notice that the arrow in the error message is pointing from HELLO to GOODBYE, but if you if you look at the `ls` output, it is pointing from GOODBYE to HELLO, which is the correct behavior. The Python3 error message should be changed to reflect the correct direction of the symlink. This is a Python3 only bug, as the paths aren't displayed in Python2. I can PR if this is accepted as a bug. Thanks!
