1.424 albertel 5070: For this documentation:
5071:
5072: 'scanline' refers to the full line of characters
5073: from the file that we are parsing that represents one entire sheet
5074:
5075: 'bubble line' refers to the data
1.659 raeburn 5076: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5077:
5078:
1.659 raeburn 5079: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5080: into a course. When a user wants to grade, they select a
1.659 raeburn 5081: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5082: one of the predefined configurations for what each scanline looks
5083: like.
5084:
5085: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5086: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5087: because too light bubbling), 'double bubble' (each bubble line should
5088: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5089: invalid student/employee ID
1.424 albertel 5090:
5091: If the CODE option is used that determines the randomization of the
1.556 weissno 5092: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5093: username:domain.
5094:
5095: During the validation phase the instructor can choose to skip scanlines.
5096:
1.659 raeburn 5097: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5098:
5099: scantron_original_filename (unmodified original file)
5100: scantron_corrected_filename (file where the corrected information has replaced the original information)
5101: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5102:
5103: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5104: correction information that isn't representable in the bubblesheet
1.424 albertel 5105: file (see &scantron_getfile() for more information)
5106:
5107: After all scanlines are either valid, marked as valid or skipped, then
5108: foreach line foreach problem in the picked sequence, an ssi request is
5109: made that simulates a user submitting their selected letter(s) against
5110: the homework problem.

10304: Apache::grades
10305:
10306: =head1 SYNOPSIS
10307:
10308: Handles the viewing of grades.
10309:
10310: This is part of the LearningOnline Network with CAPA project
10311: described at http://www.lon-capa.org.
10312:
10313: =head1 OVERVIEW
10314:
10315: Do an ssi with retries:
10316: While I'd love to factor out this with the vesrion in lonprintout,
10317: 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
10318: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10319:
10320: At least the logic that drives this has been pulled out into loncommon.
10321:
10322:
10323:
10324: ssi_with_retries - Does the server side include of a resource.
10325: if the ssi call returns an error we'll retry it up to
10326: the number of times requested by the caller.
10327: If we still have a proble, no text is appended to the
10328: output and we set some global variables.
10329: to indicate to the caller an SSI error occurred.
10330: All of this is supposed to deal with the issues described
10331: in LonCAPA BZ 5631 see:
10332: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10333: by informing the user that this happened.
10334:
10335: Parameters:
10336: resource - The resource to include. This is passed directly, without
10337: interpretation to lonnet::ssi.
10338: form - The form hash parameters that guide the interpretation of the resource
10339:
10340: retries - Number of retries allowed before giving up completely.
10341: Returns:
10342: On success, returns the rendered resource identified by the resource parameter.
10343: Side Effects:
10344: The following global variables can be set:
10345: ssi_error - If an unrecoverable error occurred this becomes true.
10346: It is up to the caller to initialize this to false
10347: if desired.
10348: ssi_error_resource - If an unrecoverable error occurred, this is the value
10349: of the resource that could not be rendered by the ssi
10350: call.
10351: ssi_error_message - The error string fetched from the ssi response
10352: in the event of an error.

10364:
10365: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10366: can receive another opportunity. Access to tasks is slot-based. If a slot
10367: requires a proctor to check-in the student, a new version of the Task will
10368: be created when the student is checked in to the new opportunity.
10369:
10370: If a particular student has tried two or more versions of a particular task,
10371: the submission screen provides a user with vgr privileges (e.g., a Course
10372: Coordinator) the ability to display a previous version worked on by the
10373: student. By default, the current version is displayed. If a previous version
10374: has been selected for display, submission data are only shown that pertain
