1.424 albertel 4999: For this documentation:
5000:
5001: 'scanline' refers to the full line of characters
5002: from the file that we are parsing that represents one entire sheet
5003:
5004: 'bubble line' refers to the data
1.596.2.6 raeburn 5005: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5006:
5007:
1.596.2.6 raeburn 5008: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5009: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5010: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5011: one of the predefined configurations for what each scanline looks
5012: like.
5013:
5014: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5015: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5016: because too light bubbling), 'double bubble' (each bubble line should
5017: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5018: invalid student/employee ID
1.424 albertel 5019:
5020: If the CODE option is used that determines the randomization of the
1.556 weissno 5021: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5022: username:domain.
5023:
5024: During the validation phase the instructor can choose to skip scanlines.
5025:
1.596.2.6 raeburn 5026: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5027:
5028: scantron_original_filename (unmodified original file)
5029: scantron_corrected_filename (file where the corrected information has replaced the original information)
5030: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5031:
5032: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5033: correction information that isn't representable in the bubblesheet
1.424 albertel 5034: file (see &scantron_getfile() for more information)
5035:
5036: After all scanlines are either valid, marked as valid or skipped, then
5037: foreach line foreach problem in the picked sequence, an ssi request is
5038: made that simulates a user submitting their selected letter(s) against
5039: the homework problem.

9802: =head1 NAME
9803:
9804: Apache::grades
9805:
9806: =head1 SYNOPSIS
9807:
9808: Handles the viewing of grades.
9809:
9810: This is part of the LearningOnline Network with CAPA project
9811: described at http://www.lon-capa.org.
9812:
9813: =head1 OVERVIEW
9814:
9815: Do an ssi with retries:
9816: While I'd love to factor out this with the vesrion in lonprintout,
9817: 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
9818: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9819:
9820: At least the logic that drives this has been pulled out into loncommon.
9821:
9822:
9823:
9824: ssi_with_retries - Does the server side include of a resource.
9825: if the ssi call returns an error we'll retry it up to
9826: the number of times requested by the caller.
9827: If we still have a proble, no text is appended to the
9828: output and we set some global variables.
9829: to indicate to the caller an SSI error occurred.
9830: All of this is supposed to deal with the issues described
9831: in LonCAPA BZ 5631 see:
9832: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9833: by informing the user that this happened.
9834:
9835: Parameters:
9836: resource - The resource to include. This is passed directly, without
9837: interpretation to lonnet::ssi.
9838: form - The form hash parameters that guide the interpretation of the resource
9839:
9840: retries - Number of retries allowed before giving up completely.
9841: Returns:
9842: On success, returns the rendered resource identified by the resource parameter.
9843: Side Effects:
9844: The following global variables can be set:
9845: ssi_error - If an unrecoverable error occurred this becomes true.
9846: It is up to the caller to initialize this to false
9847: if desired.
9848: ssi_error_resource - If an unrecoverable error occurred, this is the value
9849: of the resource that could not be rendered by the ssi
9850: call.
9851: ssi_error_message - The error string fetched from the ssi response
9852: in the event of an error.

9878: $arg - extra information needed
9879: For errors:

9883: - incorrectCODE - current incorrect CODE

9925: The parsed scanline hash is added to %env
