Description Rahul Sundaram 2009-10-16 11:26:48 UTC

Description of problem:

Now that Fedora 12 includes yum-presto by default (thanks!), what I notice even more often is that for small updates, the metadata size is often bigger than than the packages themselves. To solve this, we really need to only download the diff of the metadata or generate delta metadata on the server side and download that in preference to the full metadata.  I know this has been discussed before but I am filing it here so that there is a place to track it.

Comment 1 Bug Zapper 2009-11-16 13:44:59 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

More information and reason for this action is here:

Comment 2 Jonathan Dieter 2009-12-11 08:02:19 UTC

Reassigning to Rawhide as this is a RFE.

Comment 3 Jonathan Dieter 2009-12-27 21:17:14 UTC

Changed the summary so I can find it easier.

Comment 4 Andre Robatino 2009-12-27 21:45:28 UTC

Would it make more sense to assign this to yum (instead of yum-presto), given that applying deltas to the metadata and the RPMs can be done independently (either without the other)?

Comment 5 Jonathan Dieter 2009-12-27 22:42:17 UTC

No, it belongs here (at least for now).  There may come a point where we merge yum-presto into yum for various reasons (see https://bugzilla.redhat.com/show_bug.cgi?id=528910), but I'd rather keep all the delta-related code in the same place until that happens.

Comment 8 Kevin Fenzi 2013-04-20 18:40:00 UTC

deltarpm support has been merged in yum, so this should be a RFE against yum now?

Comment 9 Ales Kozumplik 2014-04-24 08:38:05 UTC

DNF counterpart: bug 850896. I suggest duping this one.
