os_listdir: This can be long-running, run background tasks

2019-09-10T01:14:02+00:00

While finding sources of clicks and buzzes in nrf i2sout, I identified this site as one which could be long running. Reproducer code was to play a 22.05kHz sample and repeatedly print `os.listdir('')`

shared-module/os: Fix os.mkdir('a/b')

2018-11-09T18:20:56+00:00

This fixes commit a99f9427420d("'/' and '\' are also acceptable ends of the path now") which broke mkdir. The problem is where the directory name is a single letter like this: >>> os.mkdir('a') >>> os.mkdir('a/b') Traceback (most recent call last): File "", line 1, in OSError: [Errno 17] File exists >>> os.mkdir('a/bb') >>> I wasn't smart enough to fix this in the oofatfs library, so I did it in the os shared module by creating a path lookup function for the os methods that only deals with directories. I reverted the library change introduced by the aforementioned commit. This means that os.stat and os.rename can't handle trailing slashes. This is to avoid allowing filenames with trailing slashes to pass through. In order to handle trailing slashes for these it would be necessary to check if it really is a directory before stripping. I didn't do this since the original issue was to make os.chdir tolerate trailing slashes. There's an open MicroPython issue #2929 wrt. trailing slashes and mkdir.

Split uos module into os and storage.

os is a subset of CPython's os. storage contains additional file system mounting functionality based on UNIX's mount management. Fixes #140
