Log:
Anyone currently working on lonstatistics and relying on the global variables
like %hash, will have some intergration changes to make. I will be happy to
help. The key is most of the data is now stored in the cache database. Also
look to loncoursedata.pm to see the key names.
Merged the use of loncoursedata.pm for gathering student course data. Also
using the cache data instead of the global variables. The process is about
75% complete. Student Assessment and Problem Analysis pages both work the
same as before the changes. Except for a couple of interface changes I made.
Now there is a new student and previous student buttons on the student assessment
page for cycling through the student list. Changed all students to no student
selected because all students would not display anything anyways. May add back
a all students which will display all students. Removed the section selection
from only the student assessment page. I may add this back. The problem
analysis->analyze page was already having the problem with the broken graph.gif.
The first fix for redhat 7.3 users was to download and install the lonbarcode.
The next fix will have to fix the posting data. Currently it is not reading
the information from ssi back correctly thus the post data is missing and
no rendering of the graph. This problem will be further explored.
The problem statistics page is about halfway done. The interface is up, but
you will get no data. The will be remedied over the next few days. I wanted
to submit because I was going to work a new scheme for downloading student
course data.
