<p>Beni Zihlmann called a meeting of the Documentation
Task Force on December 9. Naomi reported that a <a
href="https://halldweb.jlab.org/wiki/index.php/Software"
title="Software">wiki page</a> has been created to
give an overview of GlueX software at a beginner's
level. It is linked from the <a
href="https://halldweb.jlab.org/wiki/index.php/Main_Page"
title="Main Page">main wiki page</a> under "Overview"
in the "Software" section of the column on the right.
Writing assignments for subsidiary pages were made and
many have been fulfilled.

<h3><span class="mw-headline"
id="Last_Week.27s_Computing_Review">Last Week's
Computing Review</span></h3>
<p>Mark reported that the Review went well for us. He
thanked all those that contributed. See <a

href="https://mailman.jlab.org/pipermail/halld-offline/2021-December/008728.html">his
email from last Friday</a>.
</p>
<h3><span class="mw-headline"
id="Review_of_recent_issues_and_pull_requests">Review
of recent issues and pull requests</span></h3>
<p>We went over <a rel="nofollow" class="external text"
href="https://github.com/JeffersonLab/gluex_root_analysis/issues/156">gluex_root_analysis
Issue #156</a>: Crashes with minimal DSelector upon
writing output trees, probably memory leak.
</p>
<p>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.
</p>
<p>For now Naomi is using a two-part workaround:
</p>
<ol>
<li> process one file at a time</li>
<li> do not use PROOF</li>
</ol>
<h3><span class="mw-headline" id="Meeting_Time_in_January">Meeting
Time in January</span></h3>
<p>After the Holidays, we will go back to meeting on
Tuesdays at 3:00 pm for both the Software and HDGeant4
meetings.
