New submission from Dolda2000:
Currently, calling os.path.exists on a path which contains NUL characters
behaves consistently with most file-system calls by throwing an exception:
>>> os.path.exists('\0')

Like it says on the tin, it would be nice if strsignal(3) were added to the
signal module.

New submission from Dolda2000:
This is misfiled under Documentation since it affects the documentation
peripherally and I couldn't find any better component to file it under.
To get to the point, the website seems to have certificate troubles for some
URLs affecting the older versions
Dolda2000 added the comment:
Oh sorry, my bad. I messed up. :)
Given that that works, though, why can't open() handle opening /dev/tty
directly in text mode? Clearly, TextIOWrapper can handle the necessary
buffering without the stream having to be seekable
Dolda2000 added the comment:
So the question is, is the *design* of the IO module that '+' requires a
seekable stream the best behavior, or can that constraint be relaxed?
What purpose does that constraint serve? Is there any reason it shouldn't be
relaxed?
It seems to work quite well
New submission from Dolda2000:
It seems open() is slightly broken in Python 3, in that one cannot open
non-seekable files in read-write mode. One such common use is open(/dev/tty,
r+) for interacting directly with the controlling TTY regardless of standard
stream redirections. Note
Dolda2000 added the comment:
I don't think getpass will fail, since it uses os.open, not open.
It also uses fdopen() on the resulting file descriptor, however, which has the
same problem.
Use unbuffered binary file.
It's nice that that's at least possible, but I, for one, would still
Dolda2000 added the comment:
Just to demonstrate failure of getpass, by the way:
$ cat /tmp/pwtest.py
import getpass
print(getpass.getpass())
$ python3 /tmp/pwtest.py /dev/null
/usr/lib/python3.3/getpass.py:83: GetPassWarning: Can not control echo on the
terminal.
passwd = fallback_getpass
