Review: 1 ACK 2 ACK 3,4,5,6: New flags in API ACK, it would be good to have regression tests tracking all the events sent in the various cases... 7, 8 ACK 9 : New flag in API, sensible, ACK 10 doesn't change default behaviour, looks fine, ACK 11 ACK 12 nasty, thanks for providing a new clean iterator, ACK 13 ACK 14 good, another iterator, ACK 15 implementation of 9/ for qemu, ACK 16 ACK 17 ACK 18 ACK 19 new API flags, ACK 20 ACK 21 virsh extensions, ACK 22 ACK 23 ACK 24 ACK 25 ACK unfortunately the half baked state of 0.9.4 is gonna remain for a while 26 ACK 27 I'm not so sure about that, as the caching is infinite. Some module rely on inotify already, and best would be to add an utility for inotify use and then use it on the dirs of $PATH, then upon change discard the cacher path I would push for now but add a TODO to fix that problem 28 ACK 29 Isn't there a way to save the domain snapshot on shared storage when available to try to avoid the problem ? It wouldn't work all the time but might be simpler than rolling out a v4. or consider the snapshot data as extra domain resource that could be migrated on the fly like we can do for disk images in some cases. 30 ACK 31 ACK 32 argh ... ACK 33 the new rng need to be added to libvirt.spec.in file list, once done ACK 34 ACK 35, 36 ACK 37 ACK 38 ACK 39 ACK to new API flag 40 ACK 41 ACK 42 ACK 43 ACK 44 nice improvement, hopefully can't lead to regressions, and also end up cleaning up the code in a few places, ACK 45 useful for scripting, ACK 46 ACK 47 ACK 48 ACK 49 ACK, mechnical mostly 50 ACK 51 ACK Elapsed time: 3h 20mn now the 100hours question is how are we gonna test all this in a reasonable fashion and outside of your environment :-) I think we should push, but need a testing plan because I don't think we can reasonably expect people to test this in time for 0.9.5, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@xxxxxxxxxxxx | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/ -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
