> WindowsConsoleIO doesn't actually use the standard file descriptors > for stdin/out/err To resolve bpo-30555, _WindowsConsoleIO was changed to eliminate self->handle and get the underlying handle dynamically via _get_osfhandle(). It's thus susceptible to close() and dup2() calls in Python or a C library. This consequence was noted. The alternative was to duplicate the OS handle that self->fd wraps, isolating it from self->handle. But then self->fd could get closed, or duped to another file. Either way there are file and file-type sync problems. It's not going to work in the seamless way that people are used to in POSIX, which only uses a single io.FileIO type. I think a better resolution will be possible in the context of your side project, if you're still working on it... ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44762> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
