Return to lonsubmissiontimeanalysis.pm CVS log

Up to [LON-CAPA] / loncom / interface / statistics

Unified cache handling among statistics routines.  All use inlined progress
dialog.
&lonstatistics:&Gather_Full_Student_data now takes $formname and $inputname
    for inlined progress dialog.
&lonstathelpers: All calls to lonstatistics::Sequences_with_Assess now pass
    parameter 'all' in for mode.  Added &manage_caches which takes care of
    updating student data at the right times.  "right times" may need some
    work.  &GetStudentAnswers now takes $formname, $inputname as parameters.
&lonproblemanalysis, &lonproblemstatistics, and &lonsubmissiontimeanalysis:
    Use lonstathelpers::manage_caches and inline progress dialog.
&lonstudentsubmissions: Uses lonstathelpers::manage_caches and inlines prgwin
    Uses inlined prgwin to display further status data.
