New submission from Mond Wan <victor2...@gmail.com>:
I have tried 2 functions with different behavior across platform
# as_posix()
In linux platform, as_posix() cannot process window path nicely
* From linux + docker + python:3.8
```
Python 3.8.0 (default, Oct 17 2019, 05:36:36)
[GCC 8.3.0] on linux
>>> winPath = r'\workspace\xxx\test_fixture\user-restore-success.zip'
>>> posixPath = '/workspace/xxx/test_fixture/user-restore-success.zip'
>>> pWIN = pathlib.PurePath(winPath)
>>> pPOSIX = pathlib.PurePath(posixPath)
>>> pWIN.as_posix()
'\\workspace\\xxx\\test_fixture\\user-restore-success.zip'
>>> pPOSIX.as_posix()
'/workspace/xxx/test_fixture/user-restore-success.zip'
```
* From window + powershell + python3.6
```
Python 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 24 2018, 00:16:47) [MSC v.1916 64 bit
(AMD64)] on win32
>>> winPath = r'\workspace\xxx\test_fixture\user-restore-success.zip'
>>> posixPath = '/workspace/xxx/test_fixture/user-restore-success.zip'
>>> pWIN = pathlib.PurePath(winPath)
>>> pPOSIX = pathlib.PurePath(posixPath)
>>> pWIN.as_posix()
'/workspace/xxx/test_fixture/user-restore-success.zip'
>>> pPOSIX.as_posix()
'/workspace/xxx/test_fixture/user-restore-success.zip'
```
* From MAC
```
>>> winPath = '\\workspace\\xxx\\test_fixture\\user-restore-success.zip'
>>> posixPath = '/workspace/xxx/test_fixture/user-restore-success.zip'
>>> pWIN = pathlib.PurePath(winPath)
>>> pPOSIX = pathlib.PurePath(posixPath)
>>> pWIN.as_posix()
'\\workspace\\xxx\\test_fixture\\user-restore-success.zip'
>>> pPOSIX.as_posix()
'/workspace/xxx/test_fixture/user-restore-success.zip'
```
# resolve()
In window platform, resolve() returns absolute path only if such file is able
to locate. Otherwise, it returns
relative path.
In Linux platform, resolve() returns absolute path anyway
* From linux
```
root@b4f03ed3003b:/var/run/lock# python
Python 3.8.0 (default, Oct 17 2019, 05:36:36)

>>> import pathlib
>>> p = pathlib.Path('no_exists')
>>> p.resolve()
PosixPath('/run/lock/no_exists')
>>> str(p.resolve())
'/run/lock/no_exits'
```
* From window
```
Python 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 24 2018, 00:16:47) [MSC v.1916 64 bit

>>> import pathlib
>>> p = pathlib.Path('README.md')
>>> p.resolve()
WindowsPath('C:/Users/xxx/PycharmProjects/yyy/README.md')
>>> str(p.resolve())
'C:\\Users\\xxx\\PycharmProjects\\yyy\\README.md'
>>> p = pathlib.Path('no_exists')
>>> p.resolve()
WindowsPath('no_exists')
>>> str(p.resolve())
'no_exists'
```
Also, I have spotted a ticket similar to this one
