From dce0b0c1e30a728537abfd25cbe8a55dce22db37 Mon Sep 17 00:00:00 2001 From: "Jose M. Guisado" Date: Tue, 10 Jan 2023 10:15:24 +0100 Subject: context: fix assign_device Fixes a bug where calling assign_device with readonly keyword parameter raises exception stating it takes no keyword arguments. Context_assign_device has positional and keyword arguments. Adds flags METH_KEYWORDS in method declaration (see Context_methods). Replaces format string in PyArg_ParseTupleAndKeywords from "s|p" to "s|$p". Adds $ after |, meaning all later optional arguments are also keyword only. (See https://docs.python.org/3/c-api/arg.html#other-objects) Empty names in the kwlist array correspond to positional arguments. Replaces fname variable name with device for better readability.
