When the last callback is removed using domainEventDeregister(), the events dispatcher is deregistered from the C-library, but domainEventsCallbacks is still an empty list. On shutdown __del__() deregisters the dispatacher again, which SEGVs # You need the event-loop implementation from the Python examples; # give the file a name which is importable by Python. ln examples/domain-events/events-python/event-test.py eloop.py python -c 'from eloop import * import sys def dump(*args): print " ".join(map(str, args)) virEventLoopPureStart() c = libvirt.open("xen:///") c.domainEventRegister(dump, None) c.domainEventDeregister(dump) sys.exit(0)' domainEventDeregister() needs to delete domainEventCallbacks so subsequent calls to __del__() and domainEventRegister() choose the right code paths. Setting it to None is not enough, since calling domainEventRegiser() again would trigger an TypeError. Signed-off-by: Philipp Hahn <hahn@univention.de> |

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
