      Report from the last HDGeant4 Meeting

We went over the minutes from the meeting on October 22 
<https://halldweb.jlab.org/wiki/index.php/HDGeant4_Meeting,_October_22,_2019#Minutes>. 


  * Igal wondered if our physics list needs updating. He will post an
    issue on the HDGeant4 GitHub site.
  * We discussed missing random triggers. If MCwrapper happens to do its
    pre-run test on a run with not random triggers, the entire job
    series is stopped. The basic problem is that some runs were taken
    without random triggers. This should be caught with some sort of
    monitoring technique, but apparently the current techniques are
    inadequate, and no further work is on this is planned. Alex and Sean
    proposed substituting PS triggers for the missing random triggers
    but Beni strongly objected to this scheme. He would like to use
    random triggers from nearby runs. No volunteers for this endeavor
    came forward.


      Review of recent issues and pull requests

We started going over unresolved issues for halld_recon 
<https://github.com/JeffersonLab/halld_recon/issues?q=is%3Aissue> but 
did not have a lot of fruitful discussion. Many of the issues are very 
old, and no one has worked on their resolution for a while. Dropping the 
issues altogether was thought unwise; real problems had been identified 
when they were opened. We will to through and try to re-assess status 
offline.


      Updating Support Software Versions

Beni pointed out that many of our support software versions are very old 
now. Examples are Xerces, ROOT, Python, and there are others. Mark has 
started work on a build with the latest Xerces version and will roll 
that into a future release. We agreed it was a good idea to do a similar 
thing with the other stale packages.

Going to Python 3 is a particular problem in that much of our Python 
code is not compatible. Mostly it is the print statements without 
parentheses, but that still means files have to be edited to work with 
Python 3. This may need a group effort.
