1.424 albertel 5128: For this documentation:
5129:
5130: 'scanline' refers to the full line of characters
5131: from the file that we are parsing that represents one entire sheet
5132:
5133: 'bubble line' refers to the data
1.659 raeburn 5134: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5135:
5136:
1.659 raeburn 5137: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5138: into a course. When a user wants to grade, they select a
1.659 raeburn 5139: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5140: one of the predefined configurations for what each scanline looks
5141: like.
5142:
5143: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5144: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5145: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5146: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5147: invalid student/employee ID
1.424 albertel 5148:
5149: If the CODE option is used that determines the randomization of the
1.556 weissno 5150: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5151: username:domain.
5152:
5153: During the validation phase the instructor can choose to skip scanlines.
5154:
1.659 raeburn 5155: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5156:
5157: scantron_original_filename (unmodified original file)
5158: scantron_corrected_filename (file where the corrected information has replaced the original information)
5159: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5160:
5161: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5162: correction information that isn't representable in the bubblesheet
1.424 albertel 5163: file (see &scantron_getfile() for more information)
5164:
5165: After all scanlines are either valid, marked as valid or skipped, then
5166: foreach line foreach problem in the picked sequence, an ssi request is
5167: made that simulates a user submitting their selected letter(s) against
5168: the homework problem.

10398:
10399: Apache::grades
10400:
10401: =head1 SYNOPSIS
10402:
10403: Handles the viewing of grades.
10404:
10405: This is part of the LearningOnline Network with CAPA project
10406: described at http://www.lon-capa.org.
10407:
10408: =head1 OVERVIEW
10409:
10410: Do an ssi with retries:
1.715 bisitz 10411: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10412: 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
10413: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10414:
10415: At least the logic that drives this has been pulled out into loncommon.
10416:
10417:
10418:
10419: ssi_with_retries - Does the server side include of a resource.
10420: if the ssi call returns an error we'll retry it up to
10421: the number of times requested by the caller.
1.715 bisitz 10422: If we still have a problem, no text is appended to the
1.531 jms 10423: output and we set some global variables.
10424: to indicate to the caller an SSI error occurred.
10425: All of this is supposed to deal with the issues described
1.715 bisitz 10426: in LON-CAPA BZ 5631 see:
1.531 jms 10427: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10428: by informing the user that this happened.
10429:
10430: Parameters:
10431: resource - The resource to include. This is passed directly, without
10432: interpretation to lonnet::ssi.
10433: form - The form hash parameters that guide the interpretation of the resource
10434:
10435: retries - Number of retries allowed before giving up completely.
10436: Returns:
10437: On success, returns the rendered resource identified by the resource parameter.
10438: Side Effects:
10439: The following global variables can be set:
10440: ssi_error - If an unrecoverable error occurred this becomes true.
10441: It is up to the caller to initialize this to false
10442: if desired.
10443: ssi_error_resource - If an unrecoverable error occurred, this is the value
10444: of the resource that could not be rendered by the ssi
10445: call.
10446: ssi_error_message - The error string fetched from the ssi response
10447: in the event of an error.

1.671 raeburn 10458: =head1 Routines to display previous version of a Task for a specific student
10459:
10460: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10461: can receive another opportunity. Access to tasks is slot-based. If a slot
10462: requires a proctor to check-in the student, a new version of the Task will
10463: be created when the student is checked in to the new opportunity.
10464:
10465: If a particular student has tried two or more versions of a particular task,
