=== Review of Minutes from the Last Software Meeting ===

We went over the [[GlueX Software Meeting, December 6, 2021#Minutes|minutes from the meeting on December 6]].

==== StashCache ====

* Alex has loaded all of the 2017-01 REST files onto the cache disk. Naomi is copying them to CMU and Richard Jones is copying them to UConn.
* Igal has uploaded PrimEx calibration data, but is having problems accessing them. He will post a description of the problem to the Software Help List.

==== Documentation Upgrade ====

Beni Zihlmann called a meeting of the Documentation Task Force on December 9. Naomi reported that a [[Software|wiki page]] has been created to give an overview of GlueX software at a beginner's level. It is linked from the [[Main Page|main wiki page]] under "Overview" in the "Software" section of the column on the right. Writing assignments for subsidiary pages were made and many have been fulfilled.

=== FAQ of the Fortnight: What do I need to specify to get the correct constants from the CCDB? ===

Mark went over the details of [[GlueX_Offline_FAQ#What_do_I_need_to_specify_to_get_the_correct_constants_from_the_CCDB.3F|what is needed to fully specify]] the set of calibration constants to be used.

=== Last Week's Computing Review ===

Mark reported that the Review went well for us. He thanked all those that contributed. See [https://mailman.jlab.org/pipermail/halld-offline/2021-December/008728.html his email from last Friday].

=== Review of recent issues and pull requests ===

We went over [https://github.com/JeffersonLab/gluex_root_analysis/issues/156 gluex_root_analysis Issue #156]: Crashes with minimal DSelector upon writing output trees, probably memory leak.

Naomi told us that Paul Mattione had reported that when cloning ROOT forgets branch addresses when it uses PROOF or when it operates on a TChain[?] and so he had to write his own routine, which does not seem to work on CentOS 8. To debug the problem further she needs to go the main branch of ROOT to make sure that all recent changes have been incorporated. Mark said that he would look into adding that capability to the ROOT makefile in Build Scripts.

For now Naomi is using a two-part workaround:

# process one file at a time
# do not use PROOF

=== Meeting Time in January ===

After the Holidays, we will go back to meeting on Tuesdays at 3:00 pm for both the Software and HDGeant4 meetings.
