The %groups hash contains all the driver types (e.g. virHypervisorDriver or virSecretDriver). When searching for all the APIs that are implemented by a driver of that specific driver type, we keep iterating over the %groups hash on every line we look at, then matching against the driver type. This is inefficient because it prevents perl from caching the regex and it executes the regex once for every driver type, even though one regex matching excludes all the others, since all the driver types are different. Construct the regex containing all the driver types upfront to save about 6.4s (~98%) of the script execution time.
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.
