If the context manager isn't going to address the long-path case reliably using either a file-descriptor approach or repeated relative chdir() calls, then I think failing early like this is the next best choice. The previous directory getting deleted is a random environment error, which can be left up to the caller. In POSIX, it might be avoidable using a file-descriptor approach, but POSIX doesn't actually guarantee that fchdir() will succeed if the file descriptor refers to a deleted directory. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45545> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
