[New-bugs-announce] [issue31078] pdb's debug command (Pdb.do_debug) doesn't use rawinput even if the parent pdb uses rawinput

[Segev Finer]

New submission from Segev Finer:

This is caused by https://github.com/python/cpython/blob/caa1280d1ee5f828f346b585169a7592371d3faa/Lib/pdb.py#L1096 which always passes our own current stdin and stdout, and this triggers the conditional in https://github.com/python/cpython/blob/caa1280d1ee5f828f346b585169a7592371d3faa/Lib/pdb.py#L144-L145.

self.stdin and self.stdout are initialized to sys.stdin and sys.stdout respectively when not passed explicitly: https://github.com/python/cpython/blob/caa1280d1ee5f828f346b585169a7592371d3faa/Lib/cmd.py#L87-L94.
