[libvirt] possible bug in virConnectGetLibVersion()

I need to get libvirt version. Using function virConnecGetLibVersion(), I've return message like    errore: unknown error My system settings are:    Kernel: 2.6.33    Hypervisor: QEMU 0.12.3    Libvirt: 0.7.6 (cloned from git) The code that fails is in src/libvirt.c:1656    =========================================================        if (conn->driver->libvirtVersion) {            ret = conn->driver->libvirtVersion(conn, libVer);            if (ret < 0)                goto error;            return ret;        }        *libVer = LIBVIR_VERSION_NUMBER;        ret = 0;    error:        virDispatchError(conn);        return ret;    }    ========================================================= I noticed that conn->driver->libvirtVersion is NULL for all the hypervisors except the remote one (src/remote/remote_driver.c), hence it always dispatch an unknown error. I checked the current libvirt code (always cloned from git), and the bug is also present. Is this a bug, or this is a well known behavior? If this is a bug, a possible solution could be to add the code line    return ret; before "error:" label. This is my debugged code    =========================================================        if (conn->driver->libvirtVersion) {            ret = conn->driver->libvirtVersion(conn, libVer);            if (ret < 0)                goto error;            return ret;        }        *libVer = LIBVIR_VERSION_NUMBER;        ret = 0;        return ret; /* POSSIBLE BUG SOLUTION */    error:        virDispatchError(conn);        return ret;    }    ========================================================= Have a good day! -- PAOLO SMIRAGLIA Via Avigliana 13/5 10138 Torino (TO) Tel: 0039 333 52 73 593 E-Mail: paolo.smiraglia(a)gmail.com - - - - - MSN: mastronano(a)hotmail.com Jabber: mastronano(a)jabber.linux.it Skype: paolo.smiraglia
