Description of problem: Python 2.7 deprecated the PyCObject API in favor of a new "capsule" API. http://docs.python.org/dev/whatsnew/2.7.html#capsules The deprecations are set to "ignore" by default, so in theory the API still works. However the deprecation has caused at least one app to fail (virt-manager, see bug 620216, due to it modifying the warning settings), so I've been doublechecking the scope of usage of the PyCObject API, and am filing bugs against components that are possibly affected. You can trigger a hard failure of the API via: >>> import warnings >>> warnings.filterwarnings('error') >>> import krbV >>> krbV.AuthContext() python: krb5module.c:69: Context_init: Assertion `cobj' failed. Aborted I'm not yet sure what the best approach is to fixing this.

Created attachment 439826 [details] Initial attempt at a patch for this (doesn't yet compile) I had a go at generalizing the PyCObject usage so that it works with either PyCObject or PyCapsule; with the latter, every pointer lookup is type-checked; this could lead to a NULL return (and exception ) if the wrong types are used. Doesn't yet compile. Mike: does this approach look reasonable?
This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
