[New-bugs-announce] [issue26343] os.O_CLOEXEC not available on OS X

[Gustavo Goretkin]

New submission from Gustavo Goretkin:

I am on OS X 10.9.5

Python 3.5.1 (v3.5.1:37a07cee5969, Dec  5 2015, 21:12:44) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.O_CLOEXEC
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'os' has no attribute 'O_CLOEXEC'

I checked on my system
$ man 2 open | grep CLOEXEC
           O_CLOEXEC       mark as close-on-exec
     The O_CLOEXEC flag causes the file descriptor to be marked as close-on-
     exec, setting the FD_CLOEXEC flag.  The state of the file descriptor

I first noticed this on an anaconda distribution of python, but it looks like it is also present on the 3.5 .dmg file on https://www.python.org/downloads/
