Pull out add_rrds in an attempt to shorten functions to a manageable size
Rip out a lot of too complicated code doing reordering of
RRA rows. This is now done during the copying of the data to the
out RRA. This should also assist with the upcoming planned
population of newly added RRAs or RRA rows.
Read all input data at once - this is in preparation of upcoming code
for populating newly added rows
Add code to populate newly added RRA rows, but do not use it yet
Use code to populate new RRAs from existing data
Fix some commented out code to change RRD version when certain RRA
definitions require this.
Get rid of hard-coded hash value
Make RRA modifications work in presence of simultanous DS modifications
Add some test scripts in new tests directory
Support version 4 RRD files
Skip RRA values already defined when populating rows.
Fix off-by-one error when adding a new RRA
skip populating values for just added DS
add more test code and data required for testing
Add RRDs in tests directory to the ignore list
factor out candidate finding from populate_row
we can also use a single RRA as a candidate
make update_cdp usable from other modules
Further improve rrd modify.
I am quite sure, that this code contains a lot of hidden assumptions.
