Hi everyone,
As noted by Peter (see note to wikitech-l below), he has performed a
major upgrade of the operating system on one of our image scaler
machines, as a test for upgrading all of them (upgrading from Ubuntu
10.04 (Lucid) to Ubuntu 12.04 (Precise)). The image scalers are
responsible for generating scaled-down versions of images for
inclusions in wiki articles, as well as converting SVG images into
PNG. The great thing about this upgrade is that 12.04 comes with much
newer versions of imagemagick and librsvg, which both have many
bugfixes from their previous versions. The risky part is that the new
versions *might* introduce new bugs serious enough that things might
temporarily get worse.
So, please keep an eye on these functions over the coming days, and
report any problems you suspect are caused by this upgrade.
Thanks!
Rob

Subject: [Wikitech-l] New Imagescaler disto/packages
To: Wikimedia developers <wikitech-l(a)lists.wikimedia.org>
Hello all,
I just enabled srv190 as an imagescaler running ubuntu 12.04 precise with
new versions of imagemagick and librsvg.
This is a test for upgrading all of our imagescalers to newer versions
of... many things. Upgrading these boxes and these packages is often
problematic, so please let me know if you notice any issues with the new
setup.
Thanks!
