1.424 albertel 5123: For this documentation:
5124:
5125: 'scanline' refers to the full line of characters
5126: from the file that we are parsing that represents one entire sheet
5127:
5128: 'bubble line' refers to the data
1.659 raeburn 5129: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5130:
5131:
1.659 raeburn 5132: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5133: into a course. When a user wants to grade, they select a
1.659 raeburn 5134: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5135: one of the predefined configurations for what each scanline looks
5136: like.
5137:
5138: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5139: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5140: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5141: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5142: invalid student/employee ID
1.424 albertel 5143:
5144: If the CODE option is used that determines the randomization of the
1.556 weissno 5145: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5146: username:domain.
5147:
5148: During the validation phase the instructor can choose to skip scanlines.
5149:
1.659 raeburn 5150: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5151:
5152: scantron_original_filename (unmodified original file)
5153: scantron_corrected_filename (file where the corrected information has replaced the original information)
5154: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5155:
5156: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5157: correction information that isn't representable in the bubblesheet
1.424 albertel 5158: file (see &scantron_getfile() for more information)
5159:
5160: After all scanlines are either valid, marked as valid or skipped, then
5161: foreach line foreach problem in the picked sequence, an ssi request is
5162: made that simulates a user submitting their selected letter(s) against
5163: the homework problem.

10393:
10394: Apache::grades
10395:
10396: =head1 SYNOPSIS
10397:
10398: Handles the viewing of grades.
10399:
10400: This is part of the LearningOnline Network with CAPA project
10401: described at http://www.lon-capa.org.
10402:
10403: =head1 OVERVIEW
10404:
10405: Do an ssi with retries:
1.715 bisitz 10406: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10407: 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
10408: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10409:
10410: At least the logic that drives this has been pulled out into loncommon.
10411:
10412:
10413:
10414: ssi_with_retries - Does the server side include of a resource.
10415: if the ssi call returns an error we'll retry it up to
10416: the number of times requested by the caller.
1.715 bisitz 10417: If we still have a problem, no text is appended to the
1.531 jms 10418: output and we set some global variables.
10419: to indicate to the caller an SSI error occurred.
10420: All of this is supposed to deal with the issues described
1.715 bisitz 10421: in LON-CAPA BZ 5631 see:
1.531 jms 10422: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10423: by informing the user that this happened.
10424:
10425: Parameters:
10426: resource - The resource to include. This is passed directly, without
10427: interpretation to lonnet::ssi.
10428: form - The form hash parameters that guide the interpretation of the resource
10429:
10430: retries - Number of retries allowed before giving up completely.
10431: Returns:
10432: On success, returns the rendered resource identified by the resource parameter.
10433: Side Effects:
10434: The following global variables can be set:
10435: ssi_error - If an unrecoverable error occurred this becomes true.
10436: It is up to the caller to initialize this to false
10437: if desired.
10438: ssi_error_resource - If an unrecoverable error occurred, this is the value
10439: of the resource that could not be rendered by the ssi
10440: call.
10441: ssi_error_message - The error string fetched from the ssi response
10442: in the event of an error.

10454:
10455: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10456: can receive another opportunity. Access to tasks is slot-based. If a slot
10457: requires a proctor to check-in the student, a new version of the Task will
10458: be created when the student is checked in to the new opportunity.
10459:
10460: If a particular student has tried two or more versions of a particular task,
10461: the submission screen provides a user with vgr privileges (e.g., a Course
