1.424 albertel 5600: For this documentation:
5601:
5602: 'scanline' refers to the full line of characters
5603: from the file that we are parsing that represents one entire sheet
5604:
5605: 'bubble line' refers to the data
1.659 raeburn 5606: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5607:
5608:
1.659 raeburn 5609: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5610: into a course. When a user wants to grade, they select a
1.659 raeburn 5611: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5612: one of the predefined configurations for what each scanline looks
5613: like.
5614:
5615: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5616: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5617: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5618: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5619: invalid student/employee ID
1.424 albertel 5620:
5621: If the CODE option is used that determines the randomization of the
1.556 weissno 5622: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5623: username:domain.
5624:
5625: During the validation phase the instructor can choose to skip scanlines.
5626:
1.659 raeburn 5627: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5628:
5629: scantron_original_filename (unmodified original file)
5630: scantron_corrected_filename (file where the corrected information has replaced the original information)
5631: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5632:
5633: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5634: correction information that isn't representable in the bubblesheet
1.424 albertel 5635: file (see &scantron_getfile() for more information)
5636:
5637: After all scanlines are either valid, marked as valid or skipped, then
5638: foreach line foreach problem in the picked sequence, an ssi request is
5639: made that simulates a user submitting their selected letter(s) against
5640: the homework problem.

11385:
11386: =head1 SYNOPSIS
11387:
11388: Handles the viewing of grades.
11389:
11390: This is part of the LearningOnline Network with CAPA project
11391: described at http://www.lon-capa.org.
11392:
11393: =head1 OVERVIEW
11394:
11395: Do an ssi with retries:
1.715 bisitz 11396: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11397: 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
11398: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11399:
11400: At least the logic that drives this has been pulled out into loncommon.
11401:
11402:
11403:
11404: ssi_with_retries - Does the server side include of a resource.
11405: if the ssi call returns an error we'll retry it up to
11406: the number of times requested by the caller.
1.715 bisitz 11407: If we still have a problem, no text is appended to the
1.531 jms 11408: output and we set some global variables.
11409: to indicate to the caller an SSI error occurred.
11410: All of this is supposed to deal with the issues described
1.715 bisitz 11411: in LON-CAPA BZ 5631 see:
1.531 jms 11412: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11413: by informing the user that this happened.
11414:
11415: Parameters:
11416: resource - The resource to include. This is passed directly, without
11417: interpretation to lonnet::ssi.
11418: form - The form hash parameters that guide the interpretation of the resource
11419:
11420: retries - Number of retries allowed before giving up completely.
11421: Returns:
11422: On success, returns the rendered resource identified by the resource parameter.
11423: Side Effects:
11424: The following global variables can be set:
11425: ssi_error - If an unrecoverable error occurred this becomes true.
11426: It is up to the caller to initialize this to false
11427: if desired.
11428: ssi_error_resource - If an unrecoverable error occurred, this is the value
11429: of the resource that could not be rendered by the ssi
11430: call.
11431: ssi_error_message - The error string fetched from the ssi response
11432: in the event of an error.

1.671 raeburn 11443: =head1 Routines to display previous version of a Task for a specific student
11444:
11445: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11446: can receive another opportunity. Access to tasks is slot-based. If a slot
11447: requires a proctor to check-in the student, a new version of the Task will
11448: be created when the student is checked in to the new opportunity.
11449:
11450: If a particular student has tried two or more versions of a particular task,
11451: the submission screen provides a user with vgr privileges (e.g., a Course
11452: Coordinator) the ability to display a previous version worked on by the
11453: student. By default, the current version is displayed. If a previous version
11454: has been selected for display, submission data are only shown that pertain
