4806:
1.424 albertel 4807: For this documentation:
4808:
4809: 'scanline' refers to the full line of characters
4810: from the file that we are parsing that represents one entire sheet
4811:
4812: 'bubble line' refers to the data
4813: representing the line of bubbles that are on the physical bubble sheet
4814:
4815:
4816: The overall process is that a scanned in bubble sheet data is uploaded
4817: into a course. When a user wants to grade, they select a
4818: sequence/folder of resources, a file of bubble sheet info, and pick
4819: one of the predefined configurations for what each scanline looks
4820: like.
4821:
4822: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4823: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4824: because too light bubbling), 'double bubble' (each bubble line should
4825: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4826: invalid student/employee ID
1.424 albertel 4827:
4828: If the CODE option is used that determines the randomization of the
1.556 weissno 4829: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4830: username:domain.
4831:
4832: During the validation phase the instructor can choose to skip scanlines.
4833:
1.435 foxr 4834: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4835:
4836: scantron_original_filename (unmodified original file)
4837: scantron_corrected_filename (file where the corrected information has replaced the original information)
4838: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4839:
4840: Also there is a separate hash nohist_scantrondata that contains extra
4841: correction information that isn't representable in the bubble sheet
4842: file (see &scantron_getfile() for more information)
4843:
4844: After all scanlines are either valid, marked as valid or skipped, then
4845: foreach line foreach problem in the picked sequence, an ssi request is
4846: made that simulates a user submitting their selected letter(s) against
4847: the homework problem.

9486: =head1 NAME
9487:
9488: Apache::grades
9489:
9490: =head1 SYNOPSIS
9491:
9492: Handles the viewing of grades.
9493:
9494: This is part of the LearningOnline Network with CAPA project
9495: described at http://www.lon-capa.org.
9496:
9497: =head1 OVERVIEW
9498:
9499: Do an ssi with retries:
9500: While I'd love to factor out this with the vesrion in lonprintout,
9501: 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
9502: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9503:
9504: At least the logic that drives this has been pulled out into loncommon.
9505:
9506:
9507:
9508: ssi_with_retries - Does the server side include of a resource.
9509: if the ssi call returns an error we'll retry it up to
9510: the number of times requested by the caller.
9511: If we still have a proble, no text is appended to the
9512: output and we set some global variables.
9513: to indicate to the caller an SSI error occurred.
9514: All of this is supposed to deal with the issues described
9515: in LonCAPA BZ 5631 see:
9516: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9517: by informing the user that this happened.
9518:
9519: Parameters:
9520: resource - The resource to include. This is passed directly, without
9521: interpretation to lonnet::ssi.
9522: form - The form hash parameters that guide the interpretation of the resource
9523:
9524: retries - Number of retries allowed before giving up completely.
9525: Returns:
9526: On success, returns the rendered resource identified by the resource parameter.
9527: Side Effects:
9528: The following global variables can be set:
9529: ssi_error - If an unrecoverable error occurred this becomes true.
9530: It is up to the caller to initialize this to false
9531: if desired.
9532: ssi_error_resource - If an unrecoverable error occurred, this is the value
9533: of the resource that could not be rendered by the ssi
9534: call.
9535: ssi_error_message - The error string fetched from the ssi response
9536: in the event of an error.

9562: $arg - extra information needed
9563: For errors:

9578: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9579: calling routine should trap the error condition and display the warning

9606:
9607: Routine that does the actual grading of the bubble sheet information.
9608:
9609: The parsed scanline hash is added to %env
