New submission from Antony Lee <anntzer....@gmail.com>:
Starting from the keyword-arguments example at https://docs.python.org/3/extending/extending.html#keyword-parameters-for-extension-functions, change the docstring of `parrot` to "parrot(voltage, state, action, type=1<<5)\n--\n\n" (yes, the documented default value for type does not correspond to the actual implementation, but that's irrelevant here). Compiling the extension module and running pydoc on it yields the following parsed signature for `parrot`: `parrot(voltage, state, action)` i.e. the `type` parameter got silently dropped. (Note that `1<<5` can legitimately occur, e.g. as a bitmask flag, especially given that one currently cannot refer to globals in __text_signature__ (https://bugs.python.org/issue37881).) ---------- components: Extension Modules messages: 385335 nosy: Antony.Lee priority: normal severity: normal status: open title: __text_signature__ parser silently drops arguments with certain unsupported default forms _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42976> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
