Xv @sxdZddlZddlZddlmZd ZejdkrbGdddeZeZn ejZej Z dS) aG The temp module provides a NamedTemporaryFile that can be reopened in the same process on any platform. Most platforms use the standard Python tempfile.NamedTemporaryFile class, but Windows users are given a custom class. This is needed because the Python implementation of NamedTemporaryFile uses the O_TEMPORARY flag under Windows, which prevents the file from being reopened if the same flag is not provided [1][2]. Note that this does not address the more general issue of opening a file for writing and reading in multiple processes in a manner that works across platforms. Also note that the custom version of NamedTemporaryFile does not support the full range of keyword arguments available in Python 2.6+ and 3.0+. 1: https://mail.python.org/pipermail/python-list/2005-December/336957.html 2: http://bugs.python.org/issue14243 N)FileProxyMixinNamedTemporaryFile gettempdirntc@s|eZdZdZdddddddZejZdd Zed d Z d d Z ddZ ddZ dS) TemporaryFilea Temporary file object constructor that supports reopening of the temporary file in Windows.
