<h3><span id="gmail-m_4398089628135879743Conversion_from_Python_2_to_Python_3">Conversion
from Python 2 to Python 3</span></h3>
<p>Beni raised the issue. He is concerned that future
distributions of Linux will not support Python 2. We may
have to react to this as early as January 2020, when
support of Python 2 will be withdrawn. Mark thought that
the problem may not be all that pressing. He advocates
conversion as we identify problems maintaining critical
portions of our Python 2 code base.

<p>Beni requested a new version set. The current default

2.0 On the Way</span></h3>
<p>Mark reported that Dmitry is nearly ready to release
CCDB 2.0. It will have improvements including the
ability to freeze variation ancestors with letting the
variation of interest move forward in time. This can be
done without in a way that is fully backward compatible:
old code and new code can use the same updated schema.
The greatly simplifies implementation in comparison with
what one might have expected for a schema change.

Non-Standard HDDM Output Data</span></h3>
<p>Mark D. reported problems with genBH, an optionally
built event generator from the HDGeant4 repository. It
produces output in the hddm_mc_s schema of HDDM and not
in the usual hddm_s schema. Programs downstream of event
generation cannot grok these events. He has modified a
private version to use hddm_s. The package requires
Richard's Dirac++ package, which we do not build as part
of the standard software stack. There was discussion,
not conclusive, about whether the modified version
should be put into some other repository, presumably
halld_sim.
