Hi guys,
In openSUSE we have added support for updateinfo.xml files which we want
to use to replace our old complex patch.xml files.
As this a big step on making yum able to read our repos and libzypp able
to read other distros repos, I would like to mention the features we
will add to the spec, in case anyone is interested in adding them to
yum. I had a talk on irc yesterday with Seth Vidal and James Antill and
I got interesting feedback.
One of the changes we introduced in our updateinfo.xml generator is the
restart_suggested flag ( in addition to reboot_suggested flag ), which
is used to restart the update stack after it has updated itself before
continuing with more.
As our old patch.xml format had delta-rpm information, but this was
wrong as deltarpm information is used at commit time, and not tied to
patches but it can be used to install any package, we want to add a file
describing delta-packages in the repository. Our idea is to add the
following:
<data type="deltainfo">
<location href="repodata/deltainfo.xml.gz"/>
<checksum type="sha">5c4ca5b38c9d164263325e0414aa3442f935293a</checksum>
<timestamp>1207662520</timestamp>
<open-checksum
type="sha">8c146b5e6d1d72d3937261bf8500e1486b83bacb</open-checksum>
</data>

<packagedeltas>

<arch>i586</arch>
<version epoch="0" ver="7.1.1.0" rel="42.63"/>

</deltarpm>
</packagedeltas>
That is for now all the changes we are adding. May be we need to add
some additional attributes to updateinfo.xml, but we are still
discussing if they are necessary.
The changes I discussed with Seth and others yesterday about supporting
various updateinfo.xml files through a second index was discarded, as we
realized it would not benefit us.
cheers
