I don't think yum repos had the ChangeLogs.  They are stored in other.xml, 
and that wasn't downloaded IIRC.

I specifically remember that the memory was all taken up by the changelogs 
of the installed packaged, and the sources looked exactly the same, i.e. 
the function changelog() simply retrieved it from the rpm database.  
Nevertheless it was read in completely, someone needs to make sure that 
this doesn't happen anymore.  Besides taking space it's also very slow 
(seeking on the rpm database).

See above, I also didn't see it from just looking at the source, I also 
expected it would be done on-demand.  But someone called changelog() on 
every package just for the fun of it, and I was very surprised that it 
stayed in memory :-)  Okay, we just need to make sure that this doesn't 
happen anymore.


Ciao,
Michael.
