[Orca-users] Re: Format change in 0.27b

[Bernard]

Sorry about the length of this !
I only run orca on one production machine and it collates percol files
shared to it via nfs.

I did the upgrade you mention from .23 when we moved to .26 some time back
and it worked very well so it had those name changes.

I did the test upgrade to 0.27 on an isolated test box.  The html and rrd
files are not shared between production and development servers.
The development box was setup to run 0.26 like the production box and given
a number of percol files, only, to work with locally.
Once orca was run and the plots were created on the devel box the next test
step was to upgrade orca to 27.

I did this and the got the name changes I mentioned.
When orca starts up it prints to stdout the message "making directory
o_hostname" and it is made in the rrd/orcallator path.

Some changes from lib/Orca/RRDFile.pm :

0.26b1 :
------snip
   # Create the paths to the data directory.
   my $rrd_dir = $config_options{rrd_dir};
   if ($config_groups{$group_name}{sub_dir}) {
     $rrd_dir .= "/$subgroup_name";
     unless (-d $rrd_dir) {
       warn "$0: making directory `$rrd_dir'.\n";
       recursive_mkdir($rrd_dir);
     }
   }
   my $rrd_filename = "$rrd_dir/$name.rrd";

   # Create the new object.
-----snip

0.27b1 :
-----snip
  # Create the path to the RRD directory and filename.
   my $group_name = $config_groups_names[$group_index];
   my $dir = "$config_global{rrd_dir}/" .
             name_to_fsname("${group_name}_${subgroup_name}", 0);
   unless (-d $dir) {
     warn "$0: making directory `$dir'.\n";
     recursive_mkdir($dir);
   }
   my $rrd_filename = "$dir/$data_expression.rrd";

   # Create the new object.
-----snip

Hope this detail is helping explain.

Bernard
