[Rrd-announce] RRDtool version 1.2.28 released

[Tobias Oetiker]

Users!

I have just released a bugfix release for the rrdtool 1.2.x
series with backports of some of the 1.3 bugfixes.

  RRDtool 1.2.28

get your copy

Changes:

* updates to the win32 build makefiles

* several documetation fixes

* complain when someone tries to create an rrd file with step size
  zero.

* added filename to illegal updated interval error message.

* fix number of rows returned by python modules fetch
  implementation.

* improve compile comaptibility on aix

* fix handling of fonts with a space in their name

* fix rrd_context entries with definitions in rrd.h this prevents a
  potential segfault with long error messages.

*  make sure vdef calcs only calc as far as originally requested.

* Fixed handling of unknown data at PDP build time. There was a
  long standing (even documented) missfeature in rrdtool which
  caused uknown-data to be accepted as long as it was less than the
  mrhb.  This was never the intended behaviour and had interesting
  side effects (http://oss.oetiker.ch/rrdtool-trac/ticket/125): If
  you have a 60 Second step with 59s unknown data and 1 second of
  known data the whole become known data as long as the mrhb was >
  step.  The intended behaviour was that a step should become
  unknown as soon as it contains more than 50% of unknown data. The
  patch fixes both the documentation and the code.

* make sun studio 11 compiler happy

* fixed dst handling in parsetime.

* Generate a random cur_row for each RRA during create/restore
  operations. This effectively randomizes the block crossings among
  RRDs created around the same time. Previously, RRDs that were
  created/restored en masse would cross block boundaries
  simultaneously, which is sub-optimal. Also, this patch enables
  the user to see the RRA's cur_row pointer via rrdinfo.
