1.424 albertel 4994: For this documentation:
4995:
4996: 'scanline' refers to the full line of characters
4997: from the file that we are parsing that represents one entire sheet
4998:
4999: 'bubble line' refers to the data
1.596.2.6 raeburn 5000: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5001:
5002:
1.596.2.6 raeburn 5003: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5004: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5005: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5006: one of the predefined configurations for what each scanline looks
5007: like.
5008:
5009: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5010: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5011: because too light bubbling), 'double bubble' (each bubble line should
5012: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5013: invalid student/employee ID
1.424 albertel 5014:
5015: If the CODE option is used that determines the randomization of the
1.556 weissno 5016: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5017: username:domain.
5018:
5019: During the validation phase the instructor can choose to skip scanlines.
5020:
1.596.2.6 raeburn 5021: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5022:
5023: scantron_original_filename (unmodified original file)
5024: scantron_corrected_filename (file where the corrected information has replaced the original information)
5025: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5026:
5027: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5028: correction information that isn't representable in the bubblesheet
1.424 albertel 5029: file (see &scantron_getfile() for more information)
5030:
5031: After all scanlines are either valid, marked as valid or skipped, then
5032: foreach line foreach problem in the picked sequence, an ssi request is
5033: made that simulates a user submitting their selected letter(s) against
5034: the homework problem.

9718: =head1 NAME
9719:
9720: Apache::grades
9721:
9722: =head1 SYNOPSIS
9723:
9724: Handles the viewing of grades.
9725:
9726: This is part of the LearningOnline Network with CAPA project
9727: described at http://www.lon-capa.org.
9728:
9729: =head1 OVERVIEW
9730:
9731: Do an ssi with retries:
9732: While I'd love to factor out this with the vesrion in lonprintout,
9733: 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
9734: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9735:
9736: At least the logic that drives this has been pulled out into loncommon.
9737:
9738:
9739:
9740: ssi_with_retries - Does the server side include of a resource.
9741: if the ssi call returns an error we'll retry it up to
9742: the number of times requested by the caller.
9743: If we still have a proble, no text is appended to the
9744: output and we set some global variables.
9745: to indicate to the caller an SSI error occurred.
9746: All of this is supposed to deal with the issues described
9747: in LonCAPA BZ 5631 see:
9748: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9749: by informing the user that this happened.
9750:
9751: Parameters:
9752: resource - The resource to include. This is passed directly, without
9753: interpretation to lonnet::ssi.
9754: form - The form hash parameters that guide the interpretation of the resource
9755:
9756: retries - Number of retries allowed before giving up completely.
9757: Returns:
9758: On success, returns the rendered resource identified by the resource parameter.
9759: Side Effects:
9760: The following global variables can be set:
9761: ssi_error - If an unrecoverable error occurred this becomes true.
9762: It is up to the caller to initialize this to false
9763: if desired.
9764: ssi_error_resource - If an unrecoverable error occurred, this is the value
9765: of the resource that could not be rendered by the ssi
9766: call.
9767: ssi_error_message - The error string fetched from the ssi response
9768: in the event of an error.

9783:
9784: Arguments:
9785: $r - Apache request object
9786: $i - number of the current scanline
9787: $scan_record - hash ref as returned from &scantron_parse_scanline()
9788: $scan_config - hash ref as returned from &get_scantron_config()
9789: $line - full contents of the current scanline
9790: $error - error condition, valid values are
9791: 'incorrectCODE', 'duplicateCODE',

9793: 'duplicateID', 'incorrectID'
9794: $arg - extra information needed
9795: For errors:
9796: - duplicateID - paper number that this studentID was seen before on
9797: - duplicateCODE - array ref of the paper numbers this CODE was
9798: seen on before
9799: - incorrectCODE - current incorrect CODE
9800: - doublebubble - array ref of the bubble lines that have double
9801: bubble errors

9811: calling routine should trap the error condition and display the warning

1.531 jms 9840:
9841: The parsed scanline hash is added to %env

9843: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
