Commit cfd62c1 was incomplete; I found more cases where error messages were being overwritten, and where the code between the three registration/deregistration APIs was not consistent. Since it is fairly easy to trigger an attempt to deregister an unregistered object through public API, I also changed the error message from VIR_ERR_INTERNAL_ERROR to VIR_ERR_INVALID_ARG. * src/conf/object_event.c (virObjectEventCallbackListEventID): Inline... (virObjectEventStateEventID): ...into lone caller, and report error on failure. (virObjectEventCallbackListAddID, virObjectEventStateCallbackID) (virObjectEventCallbackListRemoveID) (virObjectEventCallbackListMarkDeleteID): Tweak error category. * src/remote/remote_driver.c (remoteConnectDomainEventRegister): Don't leak registration on failure. (remoteConnectDomainEventDeregisterAny) (remoteConnectNetworkEventDeregisterAny): Don't overwrite error. Signed-off-by: Eric Blake <eblake@redhat.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
