Most of our public APIs emit a debug log on entry, prior to anything else. There were a few exceptions where obvious failures were not logged, so fix those. When moving a debug earlier, this patch also makes sure to avoid any NULL dereference during the log (the APIs are supposed to gracefully fail if the user passes NULL for the object). However, do NOT use VIR_DEBUG prior to virInitialize, since setting up the error reporting can change where VIR_DEBUG output would be routed. Instead add documentation to virGlobalInit, virInitialize, and virGetVersion that better explains initialization. * src/libvirt.c (virGetVersion, virConnectRef, virDomainRef) (virNetworkRef, virInterfaceRef, virStoragePoolRef) (virStorageVolRef, virNodeDeviceRef, virSecretRef, virStreamRef) (virNWFilterRef, virDomainSnapshotRef): Debug on function entry. * src/libvirt-lxc.c (virDomainLxcEnterNamespace) (virDomainLxcEnterSecurityLabel): Likewise.

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.
