[issue18116] getpass.getpass() triggers ResourceWarning

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

The problem is in io.open, not in getpass. Here is a test script.

$ ./python buffered_open_fd_leak.py 
buffered_open_fd_leak.py:7: ResourceWarning: unclosed file <_io.FileIO name=3 mode='rb+'>
  tty = io.open(fd, 'w+', 1)
