Steve Dower added the comment: EBADF will still be returned; _PyVerify_fd is only there to prevent the assertion dialogs in debug builds. Release builds will not need _PyVerify_fd at all (though it's public, so it will remain, but it won't be necessary to protect calls into the CRT). As I said, there is a change coming in a CRT update that will make file calls behave more like POSIX, ie. returning EBADF instead of crashing.
See #4804 and #3545 for the discussions (and complaints) about turning off all assertion dialogs. Note that this issue only affects the dialogs in debug builds, and that for Python 3.5 we'll be making debug builds more widely available so that people can debug their extensions/hosts (see e.g. #22411). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23314> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
