Data Challengers,<br>
<br>
As you know, David was responding in real time to feedback; thus
patch 3 yesterday. Thanks to David again.<br>
<br>
Just to close the loop, jana_0.7.1.p3 ("patch 3") is the current
version. Upgrade optional as described below in the quoted message.
Where you see "patch 2" read "patch 3".<br>

Folks,<br>
<br>
Forwarding instructions from David on how to get the new tag. See
below. It is the same message as was quoted in Richard's previous
message.<br>
<br>
For the data challenge, we are asking that each site decide for
themselves whether they want to upgrade their version of JANA to
this new version, jana_0.7.1p2 (patch 2). Of course, upgrading
means re-building sim-recon against this version. Output data
files and histograms made using patch 1 are OK and need not be
re-done. Upgrade to patch 2 if you would like to eliminate even
the possibility of the errors that Richard reported. If you are
not experiencing problems, then continuing with patch 1 should be
fine. If you do upgrade, for the sake of clean living, record the
point you started up with patch 2.<br>
<br>
Thanks to David for the extremely rapid turn-around on this.<br>

<pre>Hi Richard and Mark,
I believe I now have a fix for this. I was able to reproduce the problem and after making a “minor” modification, it seems to have gone away. The only change was to add the RTLD_NODELETE flag to the call to dlopen when attaching a plugin. This basically prevents the shared object from actually being detached, therefore, preventing the multiple destructor calls. I’ve made a new JANA release, 0.7.1p2 that has this one change in it. You can download the tar ball from here:
<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://www.jlab.org/JANA/releases/jana_0.7.1p2.tgz">http://www.jlab.org/JANA/releases/jana_0.7.1p2.tgz</a>
or check out the source from subversion here:
svn co <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://phys12svn.jlab.org/repos/tags/jana_0.7.1p2">https://phys12svn.jlab.org/repos/tags/jana_0.7.1p2</a>
The minimal set of unit tests I have seemed to work OK with this so hopefully it will not give you any problems.
Regards,
-David
