Subject: Disable PyREPL in Python shell
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=80caec417b241877e71b878a615230310e009691;p=emacs.git

Disable PyREPL in Python shell

The new default REPL (PyREPL) in Python 3.13 is incompatible
with Python shell and displays a warning message when reverting
to the old basic REPL.

* lisp/progmodes/python.el
(python-shell--calculate-process-environment): Use the basic
REPL.  (Bug#76205)

(cherry picked from commit db8af88222bbf06948622d2b4fc4d27b73350b83)
