Libvirt native C API and daemons
6e130ddc4d
In datatype.c, virGetDomainSnapshot could result in the message: error: invalid domain pointer in bad domain Furthermore, while there are a few functions in libvirt.c that only care about a virDomainPtr without regards to the connection (such as virDomainGetName), most functions also require a valid connection. Yet several functions were blindly dereferencing the conn member without checking it for validity first (such as virDomainOpenConsole). Rather than try and correct all usage of VIR_IS_DOMAIN vs. VIR_IS_CONNECTED_DOMAIN, it is easier to just blindly require that a valid domain object always has a valid connection object (which should be true anyways, since every domain object holds a reference to its connection, so the connection will not be closed until all domain objects have also been closed to release their reference). After this patch, all places that validate a domain consistently report: error: invalid domain pointer in someFunc * src/datatypes.h (virCheckDomainReturn, virCheckDomainGoto): New macros. * src/datatypes.c (virGetDomainSnapshot): Use new macro. (virLibConnError): Delete unused macro. 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.
