Robert,
I did get yesterday's email that was sent to Craig and the
infrastructure mailing list. It looked like you and Craig were daytime
testing the new version; not that you wanted to run it at night.
Today is the last day of scheduled engineering time (as well as
MARVELS time). In principle, I have no problem test-running new
versions of the software at night during engineering time.I just need
to know that's the plan, and that someone will be in contact during
the testing. Your email did not indicate that.
Please let me know if you want us to run a test version tonight. If
you do, I will need some details.
1) What version it is and how to set it up (we did agree to use tags)
2) What changes to expect or what to look for (your previous email had
that)
3) Your contact info. If you are not available, and we encounter
problems, we will roll back to a previous version.
4) Which version we should roll back to in case of 3).
So, if we are to run your test versions tonight, we need your
guiderActor and platedbActor to be checked in and tagged. Please let
me know the tag numbers.
Steph
