Can I set the umask for tempfile.NamedTemporaryFile in python?
file, permissions, python
Solution
This is a security feature. The `NamedTemporaryFile` is always created with mode `0600`, hardcoded at `tempfile.py`, line 235, because it is private to your process until you open it up with `chmod`. There is no constructor argument to change this behavior.
Problem
In Python (tried this in 2.7 and below) it looks like a file created using `tempfile.NamedTemporaryFile` doesn't seem to obey the umask directive: ``` import os, tempfile os.umask(022) f1 = open ("goodfile", "w") f2 = tempfile.NamedTemporaryFile(dir='.') f2.name Out[33]: '/Users/foo/tmp4zK9Fe' ls -l -rw------- 1 foo foo 0 May 10 13:29 /Users/foo/tmp4zK9Fe -rw-r--r-- 1 foo foo 0 May 10 13:28 /Users/foo/goodfile ``` Any idea why `NamedTemporaryFile` won't pick up the umask? Is there any way to do this during file creation? I can always workaround this with os.chmod(), but I was hoping for something that did the right thing during file creation.
