Testing the new LCFG core : Part 1

The project to rework the core LCFG code is rattling along and has reached the point where some full scale testing is needed. The first step is to check whether the new XML parser can actually just parse all of our LCFG profiles. At this stage I’m not interested in whether it can do anything useful with the data once loaded, I just want to see how it handles a large number of different profiles.

Firstly a source of XML profiles is needed, I grabbed a complete local copy from our lcfg server:

rsync -av -e ssh lcfg:/var/lcfg/conf/server/web/profiles/ /disk/scratch/profiles/

I then ran the XML parser on every profile I could find:

find /disk/scratch/profiles/ -name ‘*.xml’ | xargs \
perl -MLCFG::Profile -wE \
‘for (@ARGV) { eval { LCFG::Profile->new_from_xml($_) }; print $@ if $@ }’

Initially I hit upon bug#971 which is a genuine bug in the schema for the gridengine component. As noted previously, this was found because the new libraries are much stricter about what is considered to be valid data. With that bug resolved I can now parse all 1525 LCFG XML profiles for Informatics.
