I got bit in a debugging session on an uninstalled libvirtd; the code tried to call out to the installed $LIBEXECDIR/libvirt_iohelper instead of my just-built version. So I set a breakpoint and altered the binary name to be "./src/libvirt_iohelper", and it still failed because I don't have "." on my PATH. According to POSIX, execvp only searches PATH if the name does not contain a slash. Since we are trying to mimic that behavior, an anchored name should be relative to the current working dir. This tightens existing behavior, but most callers already pass an absolute name or a name with no slashes, so it probably won't be noticeable. * src/util/util.c (virFindFileInPath): Anchored relative names do not invoke a PATH search.
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.
