Re: [Libvir] python/libvir.c returning wrong value on error?

Hi all,
Looking at python/libvir.c, all the custom functions return VIR_PY_NONE
on error. This unfortunately doesn't map well to some of the
generated python bindings which expect an error val of -1. So if these
commands fail, no exception will be thrown at the python level.
(Ex. virDomainGetAutostart, virDomainGetVcpus and their python equiv.)
I'm wondering where the fix should be: in python/libvir.c, changing
these error return values, or in the generator somewhere?
The fix should be in the libvir.c file - I didn't write this custom
bindings correctly. Simply remove the line
if (c_retval < 0)
return VIR_PY_NONE;
So 'c_retval' will get propagated back to the pure python layer which
will do the -1 check

Dan.
