4838:
4839: 'bubble line' refers to the data

1.424 albertel 4841:
4842:
1.659 ! raeburn 4843: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 4844: into a course. When a user wants to grade, they select a
1.659 ! raeburn 4845: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 4846: one of the predefined configurations for what each scanline looks
4847: like.
4848:
4849: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4850: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4851: because too light bubbling), 'double bubble' (each bubble line should
4852: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4853: invalid student/employee ID
1.424 albertel 4854:
4855: If the CODE option is used that determines the randomization of the
1.556 weissno 4856: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4857: username:domain.
4858:
4859: During the validation phase the instructor can choose to skip scanlines.
4860:
1.659 ! raeburn 4861: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 4862:
4863: scantron_original_filename (unmodified original file)
4864: scantron_corrected_filename (file where the corrected information has replaced the original information)
4865: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4866:
4867: Also there is a separate hash nohist_scantrondata that contains extra
1.659 ! raeburn 4868: correction information that isn't representable in the bubblesheet
1.424 albertel 4869: file (see &scantron_getfile() for more information)
4870:
4871: After all scanlines are either valid, marked as valid or skipped, then

9523: =head1 NAME
9524:
9525: Apache::grades
9526:
9527: =head1 SYNOPSIS
9528:
9529: Handles the viewing of grades.
9530:
9531: This is part of the LearningOnline Network with CAPA project
9532: described at http://www.lon-capa.org.
9533:
9534: =head1 OVERVIEW
9535:
9536: Do an ssi with retries:
9537: While I'd love to factor out this with the vesrion in lonprintout,
9538: 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
9539: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9540:
9541: At least the logic that drives this has been pulled out into loncommon.
9542:
9543:
9544:
9545: ssi_with_retries - Does the server side include of a resource.
9546: if the ssi call returns an error we'll retry it up to
9547: the number of times requested by the caller.
9548: If we still have a proble, no text is appended to the
9549: output and we set some global variables.
9550: to indicate to the caller an SSI error occurred.
9551: All of this is supposed to deal with the issues described
9552: in LonCAPA BZ 5631 see:
9553: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9554: by informing the user that this happened.
9555:
9556: Parameters:
9557: resource - The resource to include. This is passed directly, without
9558: interpretation to lonnet::ssi.
9559: form - The form hash parameters that guide the interpretation of the resource
9560:
9561: retries - Number of retries allowed before giving up completely.
9562: Returns:
9563: On success, returns the rendered resource identified by the resource parameter.
9564: Side Effects:
9565: The following global variables can be set:
9566: ssi_error - If an unrecoverable error occurred this becomes true.
9567: It is up to the caller to initialize this to false
9568: if desired.
9569: ssi_error_resource - If an unrecoverable error occurred, this is the value
9570: of the resource that could not be rendered by the ssi
9571: call.
9572: ssi_error_message - The error string fetched from the ssi response
9573: in the event of an error.

9599: $arg - extra information needed

9615: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9616: calling routine should trap the error condition and display the warning

1.531 jms 9645:
9646: The parsed scanline hash is added to %env
9647:
9648: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
