Description Michael Monreal 2009-05-06 13:47:23 UTC 
I have yum-presto installed. For the same list of updates, PK-updater tells me the size is 77MB. On console, yum says it's just 39MB. I guess either PK is not using presto (iirc it should at this point?) or PK just displays the total package size instead of the download - which would be more useful.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Without reading the presto source code in any great detail, I would say it's because the yum-presto code is a plugin, and hence when we ask yum the size of the update, it gives us the data without looking at the plugin data. We would have to get a presto developer to help us fix this one properly.

Richard, what do you want to do with this one.  Keep it open as a RFE or close as WONTFIX?

I am happy to help with this on the yum-presto side of things, but I'm not sure how to give you what you need.

From a given pkg, I need to know how to find the total download size of the package. At the moment I'm just using pkg.size, but for presto packages this is obviously the size of the whole rpm, not the size of the delta-rpm that needs to be downloaded. Ideas welcome. Thanks.
Comment 10 Jonathan Dieter 2009-09-17 13:09:25 UTC 
Ok, a couple of things I've noticed as I've looked a bit more closely at this.  Yum-presto does most of its work in the predownload_hook, including downloading the presto metadata, so it can't tell you anything before that (and it doesn't change yum's summary).

So I'm not sure why PK and yum have different totals, but I don't think it has anything to do with presto.  It may be that yum checks for already downloaded packages and removes them from the total.  I'm not sure if PackageKit does that.
