[libvirt] [PATCH] Makefile: Fix parallel build after Xen-xl parser introduction
by Michal Privoznik 05 Jan '15

05 Jan '15

Well, the parallel build doesn't work as there are not dependencies set correctly. When running 'make -j' I see this error: make[2]: Entering directory '/home/zippy/work/libvirt/libvirt.git/src' GEN util/virkeymaps.h GEN locking/lock_protocol.h make[2]: *** No rule to make target 'xenconfig/xen_xl_disk.h', needed by 'all'. Stop. make[2]: *** Waiting for unfinished jobs.... GEN lxc/lxc_controller_dispatch.h The fix is to correctly set dependencies by letting make know that .c and .h are to be generated from .l. Moreover, the section is moved closer to the other section which uses it. Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- I'm not fully satisfied with this patch yet. I mean, for some reason it creates 'src/.h' file, but hey - it makes parallel build work again.

[libvirt] Query: Implementation of virNetworkGetDHCPLeases
by Nehal J Wani 05 Jan '15

05 Jan '15

In the method networkGetDHCPLeases inside ./src/network/bridge_driver.c , we have: if (need_results && mac && !leases_ret) { virReportError(VIR_ERR_INTERNAL_ERROR, _("no lease with matching MAC address: %s"), mac); goto error; } Is this really required? In my opinion, since we are already filling rv with nleases (which will be 0, in case no lease corresponding to given mac is found), user will know that there is no result for his query. Why to report error? This results in: virsh # net-dhcp-leases --mac 00:50:56:c0:00:01 default error: Failed to get leases info for default error: internal error: no lease with matching MAC address: 00:50:56:c0:00:01 -- Nehal J Wani
