Fedora updates pushing: Behind the scenes
Josh Boyer takes a
behind the scenes look at recent problems with Fedora updates.
"Just before F11 release, we enabled deltarpms for updates. There
were some bumps in the first few days, but we got through it and the people
rejoiced. Everyone was happy and the Fedora updates world had a victory in
terms of end user gains. Then time went by. Updates kept getting submitted
by maintainers, and they noticed they were pushed to users less and less
frequently. Some asked on the list, and rel-eng (mostly me) blamed
deltarpms. This was not an untruth. Generating deltarpms is a pretty
intensive task, and the larger the RPMs in question, the longer it takes to
actually generate them. So our illustrious Infrastructure team took note
and increase the DRAM and number of CPUs the releng box had. This has
proved to be most helpful, and our box no longer gets kernel OOMs if the
rawhide and updates mashes happen to be going at the same time. However I
still didn't think something was right."
