New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
os.sendfile() has a keyword-or-positional parameter named "in". Since it is a keyword in Python, it is not possible to pass it as a keyword argument. You can only pass it as a positional argument or using a var-keyword argument (unlikely anybody uses the latter). The preceding parameter, "out", also can not be passed by keyword because of this. It is weird, but usually does not cause a problem. You cannot use a keyword argument, period. But it prevents os.sendfile() from converting to Argument Clinic, because Argument Clinic does not allow using Python keywords as parameter names (I already created a patch for conversion, but in needs to solve this issue first). There are two ways to solve this issue. 1. Rename parameter "in" (and maybe "out" for consistency). "out_fd" and "in_fd" look good names (they are use in Linux manpage). 2. Make "out" and "in" positional-only parameters. ---------- components: Extension Modules messages: 354012 nosy: serhiy.storchaka priority: normal severity: normal status: open title: os.sendfile() has improperly named parameter type: behavior versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38378> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
