1.424 albertel 5001: For this documentation:
5002:
5003: 'scanline' refers to the full line of characters
5004: from the file that we are parsing that represents one entire sheet
5005:
5006: 'bubble line' refers to the data
1.596.2.6 raeburn 5007: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5008:
5009:
1.596.2.6 raeburn 5010: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5011: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5012: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5013: one of the predefined configurations for what each scanline looks
5014: like.
5015:
5016: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5017: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5018: because too light bubbling), 'double bubble' (each bubble line should
5019: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5020: invalid student/employee ID
1.424 albertel 5021:
5022: If the CODE option is used that determines the randomization of the
1.556 weissno 5023: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5024: username:domain.
5025:
5026: During the validation phase the instructor can choose to skip scanlines.
5027:
1.596.2.6 raeburn 5028: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5029:
5030: scantron_original_filename (unmodified original file)
5031: scantron_corrected_filename (file where the corrected information has replaced the original information)
5032: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5033:
5034: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5035: correction information that isn't representable in the bubblesheet
1.424 albertel 5036: file (see &scantron_getfile() for more information)
5037:
5038: After all scanlines are either valid, marked as valid or skipped, then
5039: foreach line foreach problem in the picked sequence, an ssi request is
5040: made that simulates a user submitting their selected letter(s) against
5041: the homework problem.

9727: =head1 NAME
9728:
9729: Apache::grades
9730:
9731: =head1 SYNOPSIS
9732:
9733: Handles the viewing of grades.
9734:
9735: This is part of the LearningOnline Network with CAPA project
9736: described at http://www.lon-capa.org.
9737:
9738: =head1 OVERVIEW
9739:
9740: Do an ssi with retries:
9741: While I'd love to factor out this with the vesrion in lonprintout,
9742: 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
9743: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9744:
9745: At least the logic that drives this has been pulled out into loncommon.
9746:
9747:
9748:
9749: ssi_with_retries - Does the server side include of a resource.
9750: if the ssi call returns an error we'll retry it up to
9751: the number of times requested by the caller.
9752: If we still have a proble, no text is appended to the
9753: output and we set some global variables.
9754: to indicate to the caller an SSI error occurred.
9755: All of this is supposed to deal with the issues described
9756: in LonCAPA BZ 5631 see:
9757: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9758: by informing the user that this happened.
9759:
9760: Parameters:
9761: resource - The resource to include. This is passed directly, without
9762: interpretation to lonnet::ssi.
9763: form - The form hash parameters that guide the interpretation of the resource
9764:
9765: retries - Number of retries allowed before giving up completely.
9766: Returns:
9767: On success, returns the rendered resource identified by the resource parameter.
9768: Side Effects:
9769: The following global variables can be set:
9770: ssi_error - If an unrecoverable error occurred this becomes true.
9771: It is up to the caller to initialize this to false
9772: if desired.
9773: ssi_error_resource - If an unrecoverable error occurred, this is the value
9774: of the resource that could not be rendered by the ssi
9775: call.
9776: ssi_error_message - The error string fetched from the ssi response
9777: in the event of an error.

9792:
9793: Arguments:
9794: $r - Apache request object
9795: $i - number of the current scanline
9796: $scan_record - hash ref as returned from &scantron_parse_scanline()
9797: $scan_config - hash ref as returned from &get_scantron_config()
9798: $line - full contents of the current scanline
9799: $error - error condition, valid values are
9800: 'incorrectCODE', 'duplicateCODE',

9802: 'duplicateID', 'incorrectID'
9803: $arg - extra information needed
9804: For errors:
9805: - duplicateID - paper number that this studentID was seen before on
9806: - duplicateCODE - array ref of the paper numbers this CODE was
9807: seen on before
9808: - incorrectCODE - current incorrect CODE
9809: - doublebubble - array ref of the bubble lines that have double

9820: calling routine should trap the error condition and display the warning

9850: The parsed scanline hash is added to %env
