[Libvir] [PATCH] Remove dead code
Daniel P. Berrange
berrange at redhat.com
Wed Feb 7 16:58:10 UTC 2007
The attached patch removes 1000 lines of dead code from xml.c and
xend_internal.c. It is not clear that this code was ever used at
all in the past, and we certainly don't use or test it today. If
we truely need it in the future, we can trivially get it back from
the CVS repo. KIlling it now makes its easier to maintain the code
base because we're not obscuring active code with historical cruft.
Finally it will also make the code coverage reporting more useful
since it won't be complaining about untested code we never use.
Any objections to me applying this ?
Regards,
Dan.
