1.424 albertel 5507: For this documentation:
5508:
5509: 'scanline' refers to the full line of characters
5510: from the file that we are parsing that represents one entire sheet
5511:
5512: 'bubble line' refers to the data
1.596.2.6 raeburn 5513: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5514:
5515:
1.596.2.6 raeburn 5516: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5517: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5518: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5519: one of the predefined configurations for what each scanline looks
5520: like.
5521:
5522: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5523: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5524: because too light bubbling), 'double bubble' (each bubble line should
1.596.2.12.2. 0(raebur 5525:3): have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5526: invalid student/employee ID
1.424 albertel 5527:
5528: If the CODE option is used that determines the randomization of the
1.556 weissno 5529: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5530: username:domain.
5531:
5532: During the validation phase the instructor can choose to skip scanlines.
5533:
1.596.2.6 raeburn 5534: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5535:
5536: scantron_original_filename (unmodified original file)
5537: scantron_corrected_filename (file where the corrected information has replaced the original information)
5538: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5539:
5540: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5541: correction information that isn't representable in the bubblesheet
1.424 albertel 5542: file (see &scantron_getfile() for more information)
5543:
5544: After all scanlines are either valid, marked as valid or skipped, then
5545: foreach line foreach problem in the picked sequence, an ssi request is
5546: made that simulates a user submitting their selected letter(s) against
5547: the homework problem.

10821:
10822: Apache::grades
10823:
10824: =head1 SYNOPSIS
10825:
10826: Handles the viewing of grades.
10827:
10828: This is part of the LearningOnline Network with CAPA project
10829: described at http://www.lon-capa.org.
10830:
10831: =head1 OVERVIEW
10832:
10833: Do an ssi with retries:
10834: While I'd love to factor out this with the vesrion in lonprintout,
10835: 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
10836: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10837:
10838: At least the logic that drives this has been pulled out into loncommon.
10839:
10840:
10841:
10842: ssi_with_retries - Does the server side include of a resource.
10843: if the ssi call returns an error we'll retry it up to
10844: the number of times requested by the caller.
1.596.2.12.2. 8(raebur 10845:4): If we still have a problem, no text is appended to the
1.531 jms 10846: output and we set some global variables.
10847: to indicate to the caller an SSI error occurred.
10848: All of this is supposed to deal with the issues described
1.596.2.12.2. 8(raebur 10849:4): in LON-CAPA BZ 5631 see:
1.531 jms 10850: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10851: by informing the user that this happened.
10852:
10853: Parameters:
10854: resource - The resource to include. This is passed directly, without
10855: interpretation to lonnet::ssi.
10856: form - The form hash parameters that guide the interpretation of the resource
10857:
10858: retries - Number of retries allowed before giving up completely.
10859: Returns:
10860: On success, returns the rendered resource identified by the resource parameter.
10861: Side Effects:
10862: The following global variables can be set:
10863: ssi_error - If an unrecoverable error occurred this becomes true.
10864: It is up to the caller to initialize this to false
10865: if desired.
10866: ssi_error_resource - If an unrecoverable error occurred, this is the value
10867: of the resource that could not be rendered by the ssi
10868: call.
10869: ssi_error_message - The error string fetched from the ssi response
10870: in the event of an error.
