1.424 albertel 5318: For this documentation:
5319:
5320: 'scanline' refers to the full line of characters
5321: from the file that we are parsing that represents one entire sheet
5322:
5323: 'bubble line' refers to the data
1.596.2.6 raeburn 5324: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5325:
5326:
1.596.2.6 raeburn 5327: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5328: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5329: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5330: one of the predefined configurations for what each scanline looks
5331: like.
5332:
5333: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5334: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5335: because too light bubbling), 'double bubble' (each bubble line should
1.596.2.12.2. 0(raebur 5336:3): have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5337: invalid student/employee ID
1.424 albertel 5338:
5339: If the CODE option is used that determines the randomization of the
1.556 weissno 5340: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5341: username:domain.
5342:
5343: During the validation phase the instructor can choose to skip scanlines.
5344:
1.596.2.6 raeburn 5345: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5346:
5347: scantron_original_filename (unmodified original file)
5348: scantron_corrected_filename (file where the corrected information has replaced the original information)
5349: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5350:
5351: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5352: correction information that isn't representable in the bubblesheet
1.424 albertel 5353: file (see &scantron_getfile() for more information)
5354:
5355: After all scanlines are either valid, marked as valid or skipped, then
5356: foreach line foreach problem in the picked sequence, an ssi request is
5357: made that simulates a user submitting their selected letter(s) against
5358: the homework problem.

10627: =head1 NAME
10628:
10629: Apache::grades
10630:
10631: =head1 SYNOPSIS
10632:
10633: Handles the viewing of grades.
10634:
10635: This is part of the LearningOnline Network with CAPA project
10636: described at http://www.lon-capa.org.
10637:
10638: =head1 OVERVIEW
10639:
10640: Do an ssi with retries:
10641: While I'd love to factor out this with the vesrion in lonprintout,
10642: 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
10643: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10644:
10645: At least the logic that drives this has been pulled out into loncommon.
10646:
10647:
10648:
10649: ssi_with_retries - Does the server side include of a resource.
10650: if the ssi call returns an error we'll retry it up to
10651: the number of times requested by the caller.
1.596.2.12.2. 8(raebur 10652:4): If we still have a problem, no text is appended to the
1.531 jms 10653: output and we set some global variables.
10654: to indicate to the caller an SSI error occurred.
10655: All of this is supposed to deal with the issues described
1.596.2.12.2. 8(raebur 10656:4): in LON-CAPA BZ 5631 see:
1.531 jms 10657: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10658: by informing the user that this happened.
10659:
10660: Parameters:
10661: resource - The resource to include. This is passed directly, without
10662: interpretation to lonnet::ssi.
10663: form - The form hash parameters that guide the interpretation of the resource
10664:
10665: retries - Number of retries allowed before giving up completely.
10666: Returns:
10667: On success, returns the rendered resource identified by the resource parameter.
10668: Side Effects:
10669: The following global variables can be set:
10670: ssi_error - If an unrecoverable error occurred this becomes true.
10671: It is up to the caller to initialize this to false
10672: if desired.
10673: ssi_error_resource - If an unrecoverable error occurred, this is the value
10674: of the resource that could not be rendered by the ssi
10675: call.
10676: ssi_error_message - The error string fetched from the ssi response
10677: in the event of an error.
