5905:
1.424 albertel 5906: For this documentation:
5907:
5908: 'scanline' refers to the full line of characters
5909: from the file that we are parsing that represents one entire sheet
5910:
5911: 'bubble line' refers to the data
1.659 raeburn 5912: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5913:
5914:
1.659 raeburn 5915: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5916: into a course. When a user wants to grade, they select a
1.659 raeburn 5917: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5918: one of the predefined configurations for what each scanline looks
5919: like.
5920:
5921: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5922: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5923: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5924: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5925: invalid student/employee ID
1.424 albertel 5926:
5927: If the CODE option is used that determines the randomization of the
1.556 weissno 5928: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5929: username:domain.
5930:
5931: During the validation phase the instructor can choose to skip scanlines.
5932:
1.659 raeburn 5933: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5934:
5935: scantron_original_filename (unmodified original file)
5936: scantron_corrected_filename (file where the corrected information has replaced the original information)
5937: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5938:
5939: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5940: correction information that isn't representable in the bubblesheet
1.424 albertel 5941: file (see &scantron_getfile() for more information)
5942:
5943: After all scanlines are either valid, marked as valid or skipped, then
5944: foreach line foreach problem in the picked sequence, an ssi request is
5945: made that simulates a user submitting their selected letter(s) against
5946: the homework problem.

11831:
11832: =head1 SYNOPSIS
11833:
11834: Handles the viewing of grades.
11835:
11836: This is part of the LearningOnline Network with CAPA project
11837: described at http://www.lon-capa.org.
11838:
11839: =head1 OVERVIEW
11840:
11841: Do an ssi with retries:
1.715 bisitz 11842: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11843: that would either require a data coupling between modules, which I refuse to perpetuate (there's quite enough of that already), or would require the invention of another infrastructure
11844: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11845:
11846: At least the logic that drives this has been pulled out into loncommon.
11847:
11848:
11849:
11850: ssi_with_retries - Does the server side include of a resource.
11851: if the ssi call returns an error we'll retry it up to
11852: the number of times requested by the caller.
1.715 bisitz 11853: If we still have a problem, no text is appended to the
1.531 jms 11854: output and we set some global variables.
11855: to indicate to the caller an SSI error occurred.
11856: All of this is supposed to deal with the issues described
1.715 bisitz 11857: in LON-CAPA BZ 5631 see:
1.531 jms 11858: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11859: by informing the user that this happened.
11860:
11861: Parameters:
11862: resource - The resource to include. This is passed directly, without
11863: interpretation to lonnet::ssi.
11864: form - The form hash parameters that guide the interpretation of the resource
11865:
11866: retries - Number of retries allowed before giving up completely.
11867: Returns:
11868: On success, returns the rendered resource identified by the resource parameter.
11869: Side Effects:
11870: The following global variables can be set:
11871: ssi_error - If an unrecoverable error occurred this becomes true.
11872: It is up to the caller to initialize this to false
11873: if desired.
11874: ssi_error_resource - If an unrecoverable error occurred, this is the value
11875: of the resource that could not be rendered by the ssi
11876: call.
11877: ssi_error_message - The error string fetched from the ssi response
11878: in the event of an error.

1.671 raeburn 11889: =head1 Routines to display previous version of a Task for a specific student
11890:
11891: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11892: can receive another opportunity. Access to tasks is slot-based. If a slot
11893: requires a proctor to check-in the student, a new version of the Task will
11894: be created when the student is checked in to the new opportunity.
11895:
11896: If a particular student has tried two or more versions of a particular task,
11897: the submission screen provides a user with vgr privileges (e.g., a Course
11898: Coordinator) the ability to display a previous version worked on by the
11899: student. By default, the current version is displayed. If a previous version
11900: has been selected for display, submission data are only shown that pertain
11901: to that particular version, and the interface to submit grades is not shown.
