Fix CVE-2023-24816 by removing legacy code....
Fix CVE-2023-24816 by removing legacy code. Remove legacy code that might trigger a CVE. Currently set_term_title is only called with (semi-)trusted input that contain the current working directory of the current IPython session. If an attacker can control directory names, and manage to get a user cd into this directory the attacker can execute arbitrary commands contained in the folder names. Example: - On a windows machine where python is built without _ctypes, create a folder called && echo "pwn" > pwn.txt. This can be done by for example cloning a git repository. - call toggled_set_term_title(True), (or have the preference to true) - Open IPython and cd into this directory. - the folder now contain a pwn.txt, with pwn as content, despite the user not asking for any code execution. Workaround: Set the configuration option c.TerminalInteractiveShell.term_title_format='IPython' (or to any other fixed, safe string).

=====================================
Tests in example form - pure python
=====================================
This file contains doctest examples embedded as code blocks, using normal
Python prompts. See the accompanying file for similar examples using IPython
prompts (you can't mix both types within one file). The following will be run
as a test::
>>> 1+1
2
>>> print ("hello")
hello
More than one example works::
>>> s="Hello World"
>>> s.upper()
'HELLO WORLD'
but you should note that the *entire* test file is considered to be a single
test. Individual code blocks that fail are printed separately as ``example
failures``, but the whole file is still counted and reported as one test.
