+Subject: [PATCH] Fix %debug and ipdb with Python 3.15
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Python 3.15 introduced PyREPL as the default pdb input backend
+(via _maybe_use_pyrepl_as_stdin()), which temporarily sets
+use_rawinput=False before calling cmdloop(). IPython's TerminalPdb
+raises ValueError when it sees use_rawinput=False.
+
+Override _cmdloop() in IPython.core.debugger.Pdb to bypass the
+PyREPL wrapping — IPython already has its own input handling via
+prompt_toolkit and doesn't need PyREPL.
+
+Fixes: https://github.com/ipython/ipython/issues/15217
