[Libvirt-announce] Entering freeze for libvirt-2.4.0
by Daniel Veillard 31 Oct '16

31 Oct '16

As planned I just tagged the release in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Not in my normal environment this week so I hadn't had a chance to test the build before pushing, sorry about this but things went smoothly, I noticed a warning in virsh however: CC virsh-virsh-host.o vsh.c: In function 'vshReadlineParse': vsh.c:516:9: warning: 'opts_need_arg' may be used uninitialized in this function [-Wmaybe-uninitialized] i = ffsl(*opts_need_arg) - 1; ^~~~~~~~~~~~~~~~~~~~ vsh.c:2658:14: note: 'opts_need_arg' was declared here uint64_t opts_need_arg, opts_seen; ^~~~~~~~~~~~~ that probably ought to be fixed for release. I hope to be able to push RC2 during the week-end and possibly the final 2.4.0 on the 1st Nov if all goes well. please give it some testing, thanks !

I think we can just initialize the opts_need_arg with const_opts_need_arg. Michal

[Libvirt-announce] Entering freeze for libvirt-2.3.0
by Daniel Veillard 02 Oct '16

02 Oct '16

Since nobody complained about my earlier message with the release plan, I tagged libvirt-2.3.0 candidate release 1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ As usual my limited testing is really not sufficient so please give it a try, I enjoy the view of a completely green https://ci.centos.org/view/libvirt-project/ :-) but that doesn't test portability to other platforms for example ! Then I will try to push rc2 on Thursday, that way the final release can happen during the week-end or on Monday if all goes well, thanks for testing it !
