I was wrong. There's some binary magic in PyCFunction_Call It seems there is a very similar issue already reported upstream [1]. Just from top of my head, shouldn't you use PyCFunctionWithKeywords with METH_KEYWORDS [2]? [1] http://bugs.python.org/issue11587 [2] http://docs.python.org/3/c-api/structures.html#METH_KEYWORDS Ah, I was wrong, too :) Seems that this indeed is an issue, as reported yet elsewhere [1]. The proper short term solution seems to be using "METH_VARARGS | METH_KEYWORDS". Is that possible for you? I'd like to wait for the upstream to fix this so that Fedora doesn't deviate from the vanilla Python behaviour. [1] http://bugs.python.org/issue15657 Yes, I figured it out too. Wait for upstream will be probably the best. But I was really suprised when my code suddenly doesn't work and when I trying to find solution, I found only some bugs for 3.0.x reported quite long time ago and there wasn't any progress on them. So I rather report bug here, because of planned python3 default version for fedora 21 so as people could find solution here (even temporal). This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle. Changing version to '22'.

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: Calling bindings method defined like this: {"xml_f", (PyCFunction)PyCOMPS_toxml_f, METH_KEYWORDS, "write XML represenstation of COMPS to file"}, causes: SystemError: Bad call flags in PyCFunction_Call. METH_OLDARGS is no longer supported! Version-Release number of selected component (if applicable): 3.3.2-8 Howto fix: There's typo in Python-3.3.2/Objects/methodobject.c on line 83: case METH_VARARGS | METH_KEYWORDS: and should be of course: case METH_VARARGS || METH_KEYWORDS:
