Coverage for /var/srv/projects/api.amasfac.comuna18.com/tmp/venv/lib/python3.9/site-packages/django/core/files/temp.py: 21%

1""" 

2The temp module provides a NamedTemporaryFile that can be reopened in the same 

3process on any platform. Most platforms use the standard Python 

4tempfile.NamedTemporaryFile class, but Windows users are given a custom class. 

5 

6This is needed because the Python implementation of NamedTemporaryFile uses the 

7O_TEMPORARY flag under Windows, which prevents the file from being reopened 

8if the same flag is not provided [1][2]. Note that this does not address the 

9more general issue of opening a file for writing and reading in multiple 

10processes in a manner that works across platforms. 

11 

12The custom version of NamedTemporaryFile doesn't support the same keyword 

13arguments available in tempfile.NamedTemporaryFile.
