5550:
1.424 albertel 5551: For this documentation:
5552:
5553: 'scanline' refers to the full line of characters
5554: from the file that we are parsing that represents one entire sheet
5555:
5556: 'bubble line' refers to the data
1.596.2.6 raeburn 5557: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5558:
5559:
1.596.2.6 raeburn 5560: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5561: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5562: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5563: one of the predefined configurations for what each scanline looks
5564: like.
5565:
5566: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5567: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5568: because too light bubbling), 'double bubble' (each bubble line should
1.596.2.12.2. 0(raebur 5569:3): have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5570: invalid student/employee ID
1.424 albertel 5571:
5572: If the CODE option is used that determines the randomization of the
1.556 weissno 5573: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5574: username:domain.
5575:
5576: During the validation phase the instructor can choose to skip scanlines.
5577:
1.596.2.6 raeburn 5578: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5579:
5580: scantron_original_filename (unmodified original file)
5581: scantron_corrected_filename (file where the corrected information has replaced the original information)
5582: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5583:
5584: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5585: correction information that isn't representable in the bubblesheet
1.424 albertel 5586: file (see &scantron_getfile() for more information)
5587:
5588: After all scanlines are either valid, marked as valid or skipped, then
5589: foreach line foreach problem in the picked sequence, an ssi request is
5590: made that simulates a user submitting their selected letter(s) against
5591: the homework problem.

10927:
10928: Apache::grades
10929:
10930: =head1 SYNOPSIS
10931:
10932: Handles the viewing of grades.
10933:
10934: This is part of the LearningOnline Network with CAPA project
10935: described at http://www.lon-capa.org.
10936:
10937: =head1 OVERVIEW
10938:
10939: Do an ssi with retries:
10940: While I'd love to factor out this with the vesrion in lonprintout,
10941: 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
10942: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10943:
10944: At least the logic that drives this has been pulled out into loncommon.
10945:
10946:
10947:
10948: ssi_with_retries - Does the server side include of a resource.
10949: if the ssi call returns an error we'll retry it up to
10950: the number of times requested by the caller.
1.596.2.12.2. 8(raebur 10951:4): If we still have a problem, no text is appended to the
1.531 jms 10952: output and we set some global variables.
10953: to indicate to the caller an SSI error occurred.
10954: All of this is supposed to deal with the issues described
1.596.2.12.2. 8(raebur 10955:4): in LON-CAPA BZ 5631 see:
1.531 jms 10956: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10957: by informing the user that this happened.
10958:
10959: Parameters:
10960: resource - The resource to include. This is passed directly, without
10961: interpretation to lonnet::ssi.
10962: form - The form hash parameters that guide the interpretation of the resource
10963:
10964: retries - Number of retries allowed before giving up completely.
10965: Returns:
10966: On success, returns the rendered resource identified by the resource parameter.
10967: Side Effects:
10968: The following global variables can be set:
10969: ssi_error - If an unrecoverable error occurred this becomes true.
10970: It is up to the caller to initialize this to false
10971: if desired.
10972: ssi_error_resource - If an unrecoverable error occurred, this is the value
10973: of the resource that could not be rendered by the ssi
10974: call.
10975: ssi_error_message - The error string fetched from the ssi response
10976: in the event of an error.
