This is presumably due to the new default enabling of readline, where it is trying to save the history file when it exits.

For the record, why did you close as invalid?

Not sure who you meant by 'you', but just in case you meant me, Vajrasky was the one who closed it.

I closed it because I could not reproduce it anymore.

I think, it worked again after

$ ./python -S

I will open it again if I can consistently reproduce this bug.

Okay, this bug is valid. I can reproduce it in Ubuntu and Fedora.

bash-4.2$ ./python

Additional information:

When I created /home/cutecat with another user account.

bash-4.2$ ./python

Of course, so I change the ownership of /home/cutecat to cutecat. Then it works.

So what did it try to do in /home/cutecat?

[sky@localhost cpython]$ ls -la /home/cutecat/
total 8
drwxr-xr-x. 2 cutecat root 4096 Dec 6 21:50 .
drwxr-xr-x. 4 root root 4096 Dec 6 21:50 ..
-rw-------. 1 cutecat cutecat 0 Dec 6 21:50 .python_history

So I leave to core Python developers to decide whether this ticket is valid or not.

The main question here is whether "interactive user without a home directory" is a valid / common use case. I think silencing the FileNotFoundError would be ok.

(however, the "home directory with wrong permissions" case sounds crazy)

I'm getting the same PermissionError 13:

Error in atexit._run_exitfuncs:
PermissionError: [Errno 13] Permission denied

My case is: I'm running Python 3.4.0 as a non-root user in a docker.io container built on ubuntu 14.04. This user was created during the creation (Dockerfile) of the container. The user has a home directory and that directory appears to have the usual/proper permissions. When I exit the python3 REPL I get this error even if all I did was start python3 from the command line and then immediately exit.

So maybe the cause is other, or more subtle, than just a user with no home dir or home dir with unusual perms?

I can easily reproduce the problem with Docker,
and it does seem to be a permission problem:

    $ docker run -ti --rm --user="7777:7777" python:3.6.3-jessie bash -c "python3"
    Python 3.6.3 (default, Oct 10 2017, 02:29:16)

    -rw-------  1 7777 7777    0 Oct 28 14:10 .python_history

I was able to reproduce both the PermissionError and the FileNotFoundError under these circumstances:

$ docker run --user 123:123 -ti python python

In the former, the home directory is / (not writable). In the latter, the homedir is /nonexistent, which, well, doesn't exist.

My patch addresses both of these errors.
