The previous patch started a separation of error messages reported against the user-specified name, vs. tracking the canonical path that was actually opened. This patch extends that notion, by hoisting directory detection up front, passing the canonical path through the entire call chain, and simplifying lower-level functions that can now assume that a canonical path and directory have been supplied. * src/util/virstoragefile.c (virStorageFileGetMetadataFromFDInternal) (virStorageFileGetMetadataInternal): Add parameter, require directory. (virFindBackingFile): Require directory. (virStorageFileGetMetadataFromFD): Pass canonical path. (virStorageFileGetMetadataFromBuf): Likewise. (virStorageFileGetMetadata): Determine initial directory. 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.
