Cannot run under nodemon

[cebaa]

Looks like it fails to manipulate attributes:

$ nodemon ./preloaded.py j.py
...
  File ".../lib/python3.13/site-packages/preloaded/fork_server.py", line 36, in child_main
    tcattr = termios.tcgetattr(0)
termios.error: (25, 'Inappropriate ioctl for device')
...

Do you know if there are any downsides to skipping attribute save / restore when running under nodemon or similar?

No downside. I just don't handle this yet properly.

In child_main:

We should check that stdin is actually a TTY. Maybe just a try/except around the tcgetattr. This should be done before the PTY creation. Because if stdin is not a TTY, we don't need the PTY.

And if stdin is not a TTY, we can skip all the PTY logic. Or maybe it doesn't matter, it can just stay as is? I also don't remember, maybe server_handle_child really needs the PTY logic, or otherwise some heavy rewrite?

If the server (server_handle_child) needs the info (not sure): Despite _io.write_str_array(c2p_w, sys.argv), we should also pass the info whether stdin is a TTY, i.e. sth like _io.write_int(c2p_w, stdin_is_tty).

I'm not familiar to offer any useful advice, but I feel at least try / except should be better than the current situation, since it completely fails now, unless there are some edge cases where it not failing would cause more issues (can't think of any).
