#4262: Provide deltaisos for Alpha, Beta, Final

by Fedora Release Engineering

#4262: Provide deltaisos for Alpha, Beta, Final ----------------------+----------------------------------------------------- Reporter: robatino | Owner: rel-eng(a)lists.fedoraproject.org Type: task | Status: new Milestone: | Component: koji Keywords: | ----------------------+----------------------------------------------------- For a while now I've been providing deltaisos between Alpha, Beta, and Final (in addition to the ones for TCs/RCs) at [http://thepiratebay.org/user/andre14965/]. * When N Alpha is released I create 2 torrents from (N-1) Final to N Alpha (one for i386 and one for x86_64). * When N Beta is released I create 2 torrents from (N-1) Final to N Beta, and 2 torrents from N Alpha to N Beta. * When N Final is released I create 2 torrents from (N-1) Final to N Final, and 2 torrents from N Beta to N Final. For each milestone, each corresponding torrent consists of * The old and new signed checksum files for the full ISOs, * A deltaiso from the old DVD to the new DVD, and * Deltaisos from the new DVD to each of the new CDs and the new netinst (since split media is gone for F15 and later, only the one for DVD -> netinst will be needed in the future). The size of the diso for DVD -> netinst is negligible (around 50K or less). The size of the disos starting with (N-1) Final is roughly half the size of the full ISO, and increases only slightly from N Alpha to N Beta to N Final. The size of the disos for N Alpha -> N Beta and N Beta -> N Final is around 10-20% of the full ISO size (you can see the exact sizes at the above torrent link). The same exact format could be used to provide these torrents at [http://torrent.fedoraproject.org]. For direct download mirrors, just the disos could be posted. It's unnecessary to create any new signed checksum files. It may be desirable to provide a crude checksum for the disos just to make sure the download is good before running applydeltaiso (which can take a significant amount of time - around 40-45 minutes for the disos starting with (N-1) Final, and around 10-20 minutes for the ones from N Alpha -> N Beta and N Beta -> N Final - the time for DVD -> netinst is negligible). The main obstacle is that each RPM in the new ISO must be compressed using the exact same compression. For example, the recent change in xz compression means that Rawhide currently consists of RPMs built using both the old and new compression, so it would be impossible to generate working disos from 14 Final to either 15 Alpha, 15 Beta, or 15 Final. Deltaisos for 15 Alpha -> 15 Beta and 15 Beta -> 15 Final should work (assuming that the user has the new xz installed on the machine which runs applydeltaiso). For the user to temporarily change xz version is a minor nuisance - someone running anything from F11 to F14 can temporarily change the xz-\* packages to the F15/Rawhide version, and someone running F15/Rawhide can temporarily downgrade xz-\* to the F14 version. Of course it's important to restore the original versions of xz-\* after running applydeltaiso, otherwise yum-presto won't be able to apply drpms in updates. Some links regarding the xz compression change: * https://bugzilla.redhat.com/show_bug.cgi?id=644046 * http://lists.fedoraproject.org/pipermail/devel/2010-October/144651.html * http://lists.fedoraproject.org/pipermail/test/2010-October/094883.html * https://fedorahosted.org/rel-eng/ticket/4224 I volunteer to do any necessary work in creating and checking the diso content (though it's actually pretty trivial) or in writing user documentation. In closing I'd like to point out that although refining compression in order to reduce the size of full ISOs is important, at some point there will be diminishing returns (I don't know if it's reasonable to expect the large improvement of 10-15% in going from gzip to xz to happen again). On the other hand, there's no reason to expect delta compression, which reduces download size by 50% or more, to get any worse. So in the long run, it doesn't make sense to keep ignoring delta compression in the quest to make ISOs a few percent smaller. -- Ticket URL: <https://fedorahosted.org/rel-eng/ticket/4262> Fedora Release Engineering <http://fedorahosted.org/rel-eng> Release Engineering for the Fedora Project
