4818: =head1 Bubble sheet grading routines
4819:
4820: For this documentation:
4821:
4822: 'scanline' refers to the full line of characters
4823: from the file that we are parsing that represents one entire sheet
4824:
4825: 'bubble line' refers to the data
4826: representing the line of bubbles that are on the physical bubble sheet
4827:
4828:
4829: The overall process is that a scanned in bubble sheet data is uploaded
4830: into a course. When a user wants to grade, they select a
4831: sequence/folder of resources, a file of bubble sheet info, and pick
4832: one of the predefined configurations for what each scanline looks
4833: like.
4834:
4835: Next each scanline is checked for any errors of either 'missing
4836: bubbles' (it's an error because it may have been mis-scanned
4837: because too light bubbling), 'double bubble' (each bubble line should
4838: have no more that one letter picked), invalid or duplicated CODE,
4839: invalid student/employee ID
4840:
4841: If the CODE option is used that determines the randomization of the
4842: homework problems, either way the student/employee ID is looked up into a
4843: username:domain.
4844:
4845: During the validation phase the instructor can choose to skip scanlines.
4846:
4847: After the validation phase, there are now 3 bubble sheet files
4848:
4849: scantron_original_filename (unmodified original file)
4850: scantron_corrected_filename (file where the corrected information has replaced the original information)
4851: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4852:
4853: Also there is a separate hash nohist_scantrondata that contains extra
4854: correction information that isn't representable in the bubble sheet
4855: file (see &scantron_getfile() for more information)
4856:
4857: After all scanlines are either valid, marked as valid or skipped, then
4858: foreach line foreach problem in the picked sequence, an ssi request is
4859: made that simulates a user submitting their selected letter(s) against
4860: the homework problem.

9439: =head1 NAME
9440:
9441: Apache::grades
9442:
9443: =head1 SYNOPSIS
9444:
9445: Handles the viewing of grades.
9446:
9447: This is part of the LearningOnline Network with CAPA project
9448: described at http://www.lon-capa.org.
9449:
9450: =head1 OVERVIEW
9451:
9452: Do an ssi with retries:
9453: While I'd love to factor out this with the vesrion in lonprintout,
9454: 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
9455: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9456:
9457: At least the logic that drives this has been pulled out into loncommon.
9458:
9459:
9460:
9461: ssi_with_retries - Does the server side include of a resource.
9462: if the ssi call returns an error we'll retry it up to
9463: the number of times requested by the caller.
9464: If we still have a proble, no text is appended to the
9465: output and we set some global variables.
9466: to indicate to the caller an SSI error occurred.
9467: All of this is supposed to deal with the issues described
9468: in LonCAPA BZ 5631 see:
9469: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9470: by informing the user that this happened.
9471:
9472: Parameters:
9473: resource - The resource to include. This is passed directly, without
9474: interpretation to lonnet::ssi.
9475: form - The form hash parameters that guide the interpretation of the resource
9476:
9477: retries - Number of retries allowed before giving up completely.
9478: Returns:
9479: On success, returns the rendered resource identified by the resource parameter.
9480: Side Effects:
9481: The following global variables can be set:
9482: ssi_error - If an unrecoverable error occurred this becomes true.
9483: It is up to the caller to initialize this to false
9484: if desired.
9485: ssi_error_resource - If an unrecoverable error occurred, this is the value
9486: of the resource that could not be rendered by the ssi
9487: call.
9488: ssi_error_message - The error string fetched from the ssi response

9501:
9502: Builds the interface screen to interact with the operator to fix a
9503: specific error condition in a specific scanline
9504:
9505: Arguments:
9506: $r - Apache request object
9507: $i - number of the current scanline
9508: $scan_record - hash ref as returned from &scantron_parse_scanline()
9509: $scan_config - hash ref as returned from &get_scantron_config()
9510: $line - full contents of the current scanline
9511: $error - error condition, valid values are
9512: 'incorrectCODE', 'duplicateCODE',
9513: 'doublebubble', 'missingbubble',
9514: 'duplicateID', 'incorrectID'
9515: $arg - extra information needed

9530: failure to retrieve a navmap object.
9531: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9532: calling routine should trap the error condition and display the warning
9533: found in &navmap_errormsg().
9534:
9535: Returns the maximum number of bubble lines that are expected to
9536: occur. Does this by walking the selected sequence rendering the

9542: $env{'form.scantron.first_bubble_line.n'} and
9543: $env{"form.scantron.sub_bubblelines.n"}
9544: which are the total number of bubble, lines, the number of bubble
9545: lines for response n and number of the first bubble line for response n,
