* Detected by valgrind. Leak introduced in commit 5ab109f.
* python/libvirt-override.c: avoid memory leak on libvirt_virConnectOpenAuth.
* How to reproduce?
% valgrind -v --leak-check=full virt-clone --print-xml
Note: it can hit the issue although options are incomplete.
* Actual valgrind result:
==1801== 12 bytes in 1 blocks are definitely lost in loss record 25 of 3,270

libvirt Python Bindings README
==============================
Most of the libvirt python binding code is automatically generated
using the script generator.py, and the API description from
docs/libvirt-api.xml
Manually written files:
- libvirt-override.c: methods where the C binding needs to be hand crafted
- libvirt-override.py: global methods where the C and python bindings have different args
- libvirt-override-api.xml: methods where the auto-extracted API docs are not
suitable for python auto-generator. Overriding this if the method is going
into libvirt-override.c, but we still want auto-generated libvirt-override.py
- libvirt-override-virConnect.py: virConnect class methods
- typewrappers.h,.c: Python object wrappers for each libvirt C object
Auto-generated files:
- libvirt.py: The main python binding. Comprises auto-generated code, along
with contents from libvirt-override.py and libvirt-override-virConnect.py
- libvirt.c, libvirt.h: The C glue layer for the python binding. Comprises
auto-generated code, along with libvirt-override.c
- libvirt-export.c: List of auto-generated C methods, included into
the libvirt-override.c method table
