Description Dave Malcolm 2010-08-13 00:48:15 UTC
Description of problem:
Python 2.7 deprecated the PyCObject API in favor of a new "capsule" API.

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, 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')
and then use the affected part of the module (appears to be in py_guestfs_create).

./src/generator.ml:9507:    PyCObject_FromVoidPtrAndDesc ((void *) g, (char *) \"guestfs_h\", NULL);
./python/guestfs-py.c:56:    PyCObject_FromVoidPtrAndDesc ((void *) g, (char *) "guestfs_h", NULL);

I'm not yet sure what the best approach is to fixing this.
