Subject: [dsc] Errors when asking for dns_ip_version graphs
Message-ID: <4DECCDB1.9020408@ripe.net>

Hi people,

I'm running dsc-201008131729 on a CentOS 5.6 system. One of the graphs
I'm asking the grapher to generate is the "IP versions" graphs. When I
click on that in the UI, I get back no graphs. The web server log shows:

Odd number of elements in hash assignment at /usr/lib/perl5/v
endor_perl/5.8.8/DSC/extractor.pm line 247, <IN> line 1., referer:
http://dsc.ripe.net/cgi-bin/dsc-grapher.pl?plot=opcode&server=K-denic

There are many such lines, followed by:

Use of uninitialized value in addition (+) at
/usr/lib/perl5/vendor_perl/5.8.8/DSC/grapher.pm line 1251., referer:
http://dsc.ripe.net/cgi-bin/dsc-grapher.pl?plot=opcode&server=K-denic

Has anyone else had these errors? If so, do you know how to fix the code?

Anand,

This was fixed in a after that last release.  The patch is below and I will also post
a new tarball.
