<b>Executive Summary</b>: check-in any final changes to the
commissioning branch of sim-recon by C.O.B., Friday, March 6.<br>
<br>
Folks,<br>
<br>
After the offline meeting today a few of us were discussing how to
restore the sim-recon trunk (trunk/sim-recon) as the main line of
development. Recall at the collaboration meeting there was consensus
around copying the commission branch
(branches/sim-recon-commissioning) onto the trunk at some point. Now
that Justin has discovered the source of our previous problems with
the branch (simulated data not reconstructing properly due to
inappropriate calibration constants) it is beyond time that we do
the copy, branch to trunk.<br>
<br>
That having been said, one of us (David) pointed out rightly that
some people probably have un-checked-in changes to their
commissioning-branch code. As such the copy mentioned above, if done
immediately, would leave their changes off the trunk. To avoid this
we will delay the copy until 5:00 pm on Friday. In the meantime,
please check-in any changes to the commissioning branch that
represent real improvements. Those changes will then get swept to
the trunk when we do the copy on Friday.<br>
<br>
Note that if for some reason you are not able to make this deadline,
your code changes are not lost forever. There are various ways to
put them back on the trunk (description a bit too technical for this
message). See me for assistance if needed.<br>
<br>
After the copy is made, then the commissioning branch will be
considered to be at end-of-life (apart from exceptions alluded to
above, in reference to missing the deadline). All development after
that should then begin with a fresh check-out of the trunk. We will
make an announcement on this list when the copy is complete.<br>
<br>
After we move off the branch, there will still be a need to analyze
data from the Fall run obviously. To do that you need to build
sim-recon against the commissioning branch of HDDS (i. e., you must
still use the commissioning geometry). Alternately, you could
continue to use the commissioning branch of sim-recon, just know
that further improvements to that code base will not be coming in.
For the upcoming run, since the trunk of HDDS (geometry) has the
hydrogen target and the default beam line components, it should be
used.<br>
<br>
Finally, if you have objections to this plan, please let me know
before Friday, 5 pm.<br>
