1.424 albertel 5129: For this documentation:
5130:
5131: 'scanline' refers to the full line of characters
5132: from the file that we are parsing that represents one entire sheet
5133:
5134: 'bubble line' refers to the data
1.659 raeburn 5135: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5136:
5137:
1.659 raeburn 5138: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5139: into a course. When a user wants to grade, they select a
1.659 raeburn 5140: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5141: one of the predefined configurations for what each scanline looks
5142: like.
5143:
5144: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5145: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5146: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5147: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5148: invalid student/employee ID
1.424 albertel 5149:
5150: If the CODE option is used that determines the randomization of the
1.556 weissno 5151: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5152: username:domain.
5153:
5154: During the validation phase the instructor can choose to skip scanlines.
5155:
1.659 raeburn 5156: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5157:
5158: scantron_original_filename (unmodified original file)
5159: scantron_corrected_filename (file where the corrected information has replaced the original information)
5160: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5161:
5162: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5163: correction information that isn't representable in the bubblesheet
1.424 albertel 5164: file (see &scantron_getfile() for more information)
5165:
5166: After all scanlines are either valid, marked as valid or skipped, then
5167: foreach line foreach problem in the picked sequence, an ssi request is
5168: made that simulates a user submitting their selected letter(s) against
5169: the homework problem.

10399:
10400: Apache::grades
10401:
10402: =head1 SYNOPSIS
10403:
10404: Handles the viewing of grades.
10405:
10406: This is part of the LearningOnline Network with CAPA project
10407: described at http://www.lon-capa.org.
10408:
10409: =head1 OVERVIEW
10410:
10411: Do an ssi with retries:
1.715 bisitz 10412: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10413: 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
10414: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10415:
10416: At least the logic that drives this has been pulled out into loncommon.
10417:
10418:
10419:
10420: ssi_with_retries - Does the server side include of a resource.
10421: if the ssi call returns an error we'll retry it up to
10422: the number of times requested by the caller.
1.715 bisitz 10423: If we still have a problem, no text is appended to the
1.531 jms 10424: output and we set some global variables.
10425: to indicate to the caller an SSI error occurred.
10426: All of this is supposed to deal with the issues described
1.715 bisitz 10427: in LON-CAPA BZ 5631 see:
1.531 jms 10428: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10429: by informing the user that this happened.
10430:
10431: Parameters:
10432: resource - The resource to include. This is passed directly, without
10433: interpretation to lonnet::ssi.
10434: form - The form hash parameters that guide the interpretation of the resource
10435:
10436: retries - Number of retries allowed before giving up completely.
10437: Returns:
10438: On success, returns the rendered resource identified by the resource parameter.
10439: Side Effects:
10440: The following global variables can be set:
10441: ssi_error - If an unrecoverable error occurred this becomes true.
10442: It is up to the caller to initialize this to false
10443: if desired.
10444: ssi_error_resource - If an unrecoverable error occurred, this is the value
10445: of the resource that could not be rendered by the ssi
10446: call.
10447: ssi_error_message - The error string fetched from the ssi response
10448: in the event of an error.

1.671 raeburn 10459: =head1 Routines to display previous version of a Task for a specific student
10460:
10461: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10462: can receive another opportunity. Access to tasks is slot-based. If a slot
10463: requires a proctor to check-in the student, a new version of the Task will
10464: be created when the student is checked in to the new opportunity.
10465:
10466: If a particular student has tried two or more versions of a particular task,
