1.424 albertel 5509: For this documentation:
5510:
5511: 'scanline' refers to the full line of characters
5512: from the file that we are parsing that represents one entire sheet
5513:
5514: 'bubble line' refers to the data
1.596.2.6 raeburn 5515: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5516:
5517:
1.596.2.6 raeburn 5518: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5519: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5520: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5521: one of the predefined configurations for what each scanline looks
5522: like.
5523:
5524: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5525: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5526: because too light bubbling), 'double bubble' (each bubble line should
1.596.2.12.2. 0(raebur 5527:3): have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5528: invalid student/employee ID
1.424 albertel 5529:
5530: If the CODE option is used that determines the randomization of the
1.556 weissno 5531: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5532: username:domain.
5533:
5534: During the validation phase the instructor can choose to skip scanlines.
5535:
1.596.2.6 raeburn 5536: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5537:
5538: scantron_original_filename (unmodified original file)
5539: scantron_corrected_filename (file where the corrected information has replaced the original information)
5540: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5541:
5542: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5543: correction information that isn't representable in the bubblesheet
1.424 albertel 5544: file (see &scantron_getfile() for more information)
5545:
5546: After all scanlines are either valid, marked as valid or skipped, then
5547: foreach line foreach problem in the picked sequence, an ssi request is
5548: made that simulates a user submitting their selected letter(s) against
5549: the homework problem.

10885:
10886: Apache::grades
10887:
10888: =head1 SYNOPSIS
10889:
10890: Handles the viewing of grades.
10891:
10892: This is part of the LearningOnline Network with CAPA project
10893: described at http://www.lon-capa.org.
10894:
10895: =head1 OVERVIEW
10896:
10897: Do an ssi with retries:
10898: While I'd love to factor out this with the vesrion in lonprintout,
10899: 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
10900: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10901:
10902: At least the logic that drives this has been pulled out into loncommon.
10903:
10904:
10905:
10906: ssi_with_retries - Does the server side include of a resource.
10907: if the ssi call returns an error we'll retry it up to
10908: the number of times requested by the caller.
1.596.2.12.2. 8(raebur 10909:4): If we still have a problem, no text is appended to the
1.531 jms 10910: output and we set some global variables.
10911: to indicate to the caller an SSI error occurred.
10912: All of this is supposed to deal with the issues described
1.596.2.12.2. 8(raebur 10913:4): in LON-CAPA BZ 5631 see:
1.531 jms 10914: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10915: by informing the user that this happened.
10916:
10917: Parameters:
10918: resource - The resource to include. This is passed directly, without
10919: interpretation to lonnet::ssi.
10920: form - The form hash parameters that guide the interpretation of the resource
10921:
10922: retries - Number of retries allowed before giving up completely.
10923: Returns:
10924: On success, returns the rendered resource identified by the resource parameter.
10925: Side Effects:
10926: The following global variables can be set:
10927: ssi_error - If an unrecoverable error occurred this becomes true.
10928: It is up to the caller to initialize this to false
10929: if desired.
10930: ssi_error_resource - If an unrecoverable error occurred, this is the value
10931: of the resource that could not be rendered by the ssi
10932: call.
10933: ssi_error_message - The error string fetched from the ssi response
10934: in the event of an error.
