From 305d78b71481e309051b1b88f363805d8c0ad34a Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Fri, 26 May 2023 11:42:36 -0700 Subject: [3.12] GH-103631: Fix `PurePosixPath(PureWindowsPath(...))` separator handling (GH-104949) (GH-104991) For backwards compatibility, accept backslashes as path separators in `PurePosixPath` if an instance of `PureWindowsPath` is supplied. This restores behaviour from Python 3.11. (cherry picked from commit 328422ce6162eb18735a2c0de12f8a696be97d0c) Co-authored-by: Barney Gale Co-authored-by: Gregory P.
