4817: =head1 Bubble sheet grading routines
4818:
4819: For this documentation:
4820:
4821: 'scanline' refers to the full line of characters
4822: from the file that we are parsing that represents one entire sheet
4823:
4824: 'bubble line' refers to the data
4825: representing the line of bubbles that are on the physical bubble sheet
4826:
4827:
4828: The overall process is that a scanned in bubble sheet data is uploaded
4829: into a course. When a user wants to grade, they select a
4830: sequence/folder of resources, a file of bubble sheet info, and pick
4831: one of the predefined configurations for what each scanline looks
4832: like.
4833:
4834: Next each scanline is checked for any errors of either 'missing
4835: bubbles' (it's an error because it may have been mis-scanned
4836: because too light bubbling), 'double bubble' (each bubble line should
4837: have no more that one letter picked), invalid or duplicated CODE,
4838: invalid student/employee ID
4839:
4840: If the CODE option is used that determines the randomization of the
4841: homework problems, either way the student/employee ID is looked up into a
4842: username:domain.
4843:
4844: During the validation phase the instructor can choose to skip scanlines.
4845:
4846: After the validation phase, there are now 3 bubble sheet files
4847:
4848: scantron_original_filename (unmodified original file)
4849: scantron_corrected_filename (file where the corrected information has replaced the original information)
4850: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4851:
4852: Also there is a separate hash nohist_scantrondata that contains extra
4853: correction information that isn't representable in the bubble sheet
4854: file (see &scantron_getfile() for more information)
4855:
4856: After all scanlines are either valid, marked as valid or skipped, then
4857: foreach line foreach problem in the picked sequence, an ssi request is
4858: made that simulates a user submitting their selected letter(s) against
4859: the homework problem.

9438: =head1 NAME
9439:
9440: Apache::grades
9441:
9442: =head1 SYNOPSIS
9443:
9444: Handles the viewing of grades.
9445:
9446: This is part of the LearningOnline Network with CAPA project
9447: described at http://www.lon-capa.org.
9448:
9449: =head1 OVERVIEW
9450:
9451: Do an ssi with retries:
9452: While I'd love to factor out this with the vesrion in lonprintout,
9453: 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
9454: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9455:
9456: At least the logic that drives this has been pulled out into loncommon.
9457:
9458:
9459:
9460: ssi_with_retries - Does the server side include of a resource.
9461: if the ssi call returns an error we'll retry it up to
9462: the number of times requested by the caller.
9463: If we still have a proble, no text is appended to the
9464: output and we set some global variables.
9465: to indicate to the caller an SSI error occurred.
9466: All of this is supposed to deal with the issues described
9467: in LonCAPA BZ 5631 see:
9468: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9469: by informing the user that this happened.
9470:
9471: Parameters:
9472: resource - The resource to include. This is passed directly, without
9473: interpretation to lonnet::ssi.
9474: form - The form hash parameters that guide the interpretation of the resource
9475:
9476: retries - Number of retries allowed before giving up completely.
9477: Returns:
9478: On success, returns the rendered resource identified by the resource parameter.
9479: Side Effects:
9480: The following global variables can be set:
9481: ssi_error - If an unrecoverable error occurred this becomes true.
9482: It is up to the caller to initialize this to false
9483: if desired.
9484: ssi_error_resource - If an unrecoverable error occurred, this is the value
9485: of the resource that could not be rendered by the ssi
9486: call.
9487: ssi_error_message - The error string fetched from the ssi response

9501: Builds the interface screen to interact with the operator to fix a
9502: specific error condition in a specific scanline
9503:
9504: Arguments:
9505: $r - Apache request object
9506: $i - number of the current scanline
9507: $scan_record - hash ref as returned from &scantron_parse_scanline()
9508: $scan_config - hash ref as returned from &get_scantron_config()
9509: $line - full contents of the current scanline
9510: $error - error condition, valid values are

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

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