Re: [libvirt] [PATCH] virsh: don't shorten incorrect arguments

With short option bundling, this results in $ tools/virsh -rd error: option '-rd' requires an argument even though the -r option was just fine, and it is really just the bundled '-d' option that has a problem. Also, I wonder if we should be using a non-NULL 5th parameter to getopt_long; if you provide a longindex parameter, then you can provide a nicer error message that mentions the full "--debug" name (rather than the user-typed abbreviation '--debu') by indexing back into the long-option table (of course, do this only when it was a long option that was misused). It's a strict improvement over what we currently have, but I'm wondering if we should try for a v2 that does even better. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
