 1. Doxygen sites for halld_recon and halld_sim
    Mark announce the working Doxygen sites for halld_recon and
    halld_sim. We discussed how we might improve them.
      * We will try educate ourselves on what is possible to do with
        Doxygen. Beni and Alex posted link which Mark will collect into
        a wiki page.
      * Richard suggested asking people in the High Energy community if
        they have developed best practices for configuring Doxygen, or
        indeed whether they are using Doxygen as a code documentation
        tool still.
 2. Advanced support versions, bug fixes, and a new version set: 5.0.1
    We are now back with advanced versions of ROOT and Geant4 as the

      Review of Minutes from the Last Software Meeting

We went over the Minutes from the September 27th meeting 
Alex pointed out that we need a new set of recon-launch compatible 
builds to go with the current master branch of halld_sim. There are 
fixes to the beam properties class, used by some of our generators, that 
is not captured in the last tagged version.

      Review of Minutes from the Last HDGeant4 Meeting

We went over the minutes from the meeting on October 4th 
We need to verify that the current version of Geant4, 10.04, fixes 
HDGeant4 Issue #195: Crash adding daughters on RHEL/CentOS 8 

      FAQ of the Fortnight: How do I restart the automatic pull-request

We went over the FAQ 
that describes the procedure. This action is appropriate when it is 
known that a pull-request test failed due to external circumstances, 
those unrelated to the content of the code in the request, and the issue 
with those circumstances have been resolved. Note that the restart 
requires admin privileges on the repository in question (halld_recon or 
halld_sim). Only members of the gluex_admin team 
<https://github.com/orgs/JeffersonLab/teams/gluex-admin/members> have 
this privilege. Collaborators without admin privilege can trigger a 
re-test by pushing an additional change (including changes which do not 
affect the operation of the code) to the branch on GitHub which is the 
subject of the pull request.

      Review of recent issues and pull requests

Alex reported that he is still seeing crashes described in halld_recon 
Issue #81, DL1MCTrigger Crashes With mysql rcdb/ccdb 
<https://github.com/JeffersonLab/halld_recon/issues/81>, first reported 
in January 2019 by Jon Zarling. The odd thing about this one is that 
failures only occur on RCDB access to the MySQL server and not when 
using an SQLite file. Alex will put together a simple test case and 
Richard will have a look at it.

      Action Item Review

 1. Create a Wiki page of Doxygen links. (Mark)
 2. Ask the HEP Software Foundation about code documentation best practices.
 3. Create new tagged version of halld_sim and corresponding
    recon-launch compatible version sets. (Mark)
 4. Add Alex to the gluex_admin team on GitHub. (Mark)
 5. Add non-privileged pull-request-re-test procedure to the FAQ.
