Regression with Python 3.5.0 final

[squeaky-pl]

I get a following stacktrace:

Traceback (most recent call last):
  File "upyc/minimal.py", line 12, in <module>
    main()
  File "upyc/minimal.py", line 7, in main
    foo = gevent.subprocess.Popen([sys.executable, '--version'])
  File "/data/venv/lib/python3.5/site-packages/gevent/subprocess.py", line 415, in __init__
    restore_signals, start_new_session)
  File "/data/venv/lib/python3.5/site-packages/gevent/subprocess.py", line 1100, in _execute_child
    raise child_exception
NameError: name 'MAXFD' is not defined

running following minimal example

import sys

import gevent.subprocess


def main():
    foo = gevent.subprocess.Popen([sys.executable, '--version'])
    foo.wait()


if __name__ == '__main__':
    main()

Platform information

python --version     
Python 3.5.0
uname -a       
Linux 59e85089ab62 4.1.6-200.fc22.x86_64 #1 SMP Mon Aug 17 19:54:31 UTC 2015 x86_64 Linux
pip freeze | grep gevent
gevent==1.1b4

This seems to be related to changes in Python 3.5 stdlib, it worked perfectly with 3.4

It seems that MAXFD is gone in Python 3.5 according to this comment here:

I realized that you don't have Python 3.5 in your test matrix. I run the test suite under Python 3.5:
I include output of make fulltoxtest here (if that helps):

Awesome, Travis CI already supports Python 3.5: http://docs.travis-ci.com/user/languages/python/

After the official Python 3.4 release, Travis CI needed a couple of weeks before they supported it.

I found exact commit where MAXFD was removed: https://hg.python.org/cpython/rev/f98b0a5e5ef5
