5547:
1.424 albertel 5548: For this documentation:
5549:
5550: 'scanline' refers to the full line of characters
5551: from the file that we are parsing that represents one entire sheet
5552:
5553: 'bubble line' refers to the data
1.596.2.6 raeburn 5554: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5555:
5556:
1.596.2.6 raeburn 5557: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5558: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5559: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5560: one of the predefined configurations for what each scanline looks
5561: like.
5562:
5563: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5564: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5565: because too light bubbling), 'double bubble' (each bubble line should
1.596.2.12.2. 0(raebur 5566:3): have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5567: invalid student/employee ID
1.424 albertel 5568:
5569: If the CODE option is used that determines the randomization of the
1.556 weissno 5570: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5571: username:domain.
5572:
5573: During the validation phase the instructor can choose to skip scanlines.
5574:
1.596.2.6 raeburn 5575: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5576:
5577: scantron_original_filename (unmodified original file)
5578: scantron_corrected_filename (file where the corrected information has replaced the original information)
5579: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5580:
5581: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5582: correction information that isn't representable in the bubblesheet
1.424 albertel 5583: file (see &scantron_getfile() for more information)
5584:
5585: After all scanlines are either valid, marked as valid or skipped, then
5586: foreach line foreach problem in the picked sequence, an ssi request is
5587: made that simulates a user submitting their selected letter(s) against
5588: the homework problem.

10891:
10892: Apache::grades
10893:
10894: =head1 SYNOPSIS
10895:
10896: Handles the viewing of grades.
10897:
10898: This is part of the LearningOnline Network with CAPA project
10899: described at http://www.lon-capa.org.
10900:
10901: =head1 OVERVIEW
10902:
10903: Do an ssi with retries:
10904: While I'd love to factor out this with the vesrion in lonprintout,
10905: 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
10906: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10907:
10908: At least the logic that drives this has been pulled out into loncommon.
10909:
10910:
10911:
10912: ssi_with_retries - Does the server side include of a resource.
10913: if the ssi call returns an error we'll retry it up to
10914: the number of times requested by the caller.
1.596.2.12.2. 8(raebur 10915:4): If we still have a problem, no text is appended to the
1.531 jms 10916: output and we set some global variables.
10917: to indicate to the caller an SSI error occurred.
10918: All of this is supposed to deal with the issues described
1.596.2.12.2. 8(raebur 10919:4): in LON-CAPA BZ 5631 see:
1.531 jms 10920: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10921: by informing the user that this happened.
10922:
10923: Parameters:
10924: resource - The resource to include. This is passed directly, without
10925: interpretation to lonnet::ssi.
10926: form - The form hash parameters that guide the interpretation of the resource
10927:
10928: retries - Number of retries allowed before giving up completely.
10929: Returns:
10930: On success, returns the rendered resource identified by the resource parameter.
10931: Side Effects:
10932: The following global variables can be set:
10933: ssi_error - If an unrecoverable error occurred this becomes true.
10934: It is up to the caller to initialize this to false
10935: if desired.
10936: ssi_error_resource - If an unrecoverable error occurred, this is the value
10937: of the resource that could not be rendered by the ssi
10938: call.
10939: ssi_error_message - The error string fetched from the ssi response
10940: in the event of an error.
