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

10953: =head1 NAME
10954:
10955: Apache::grades
10956:
10957: =head1 SYNOPSIS
10958:
10959: Handles the viewing of grades.
10960:
10961: This is part of the LearningOnline Network with CAPA project
10962: described at http://www.lon-capa.org.
10963:
10964: =head1 OVERVIEW
10965:
10966: Do an ssi with retries:
10967: While I'd love to factor out this with the vesrion in lonprintout,
10968: 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
10969: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10970:
10971: At least the logic that drives this has been pulled out into loncommon.
10972:
10973:
10974:
10975: ssi_with_retries - Does the server side include of a resource.
10976: if the ssi call returns an error we'll retry it up to
10977: the number of times requested by the caller.
1.596.2.12.2. 8(raebur 10978:4): If we still have a problem, no text is appended to the
1.531 jms 10979: output and we set some global variables.
10980: to indicate to the caller an SSI error occurred.
10981: All of this is supposed to deal with the issues described
1.596.2.12.2. 8(raebur 10982:4): in LON-CAPA BZ 5631 see:
1.531 jms 10983: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10984: by informing the user that this happened.
10985:
10986: Parameters:
10987: resource - The resource to include. This is passed directly, without
10988: interpretation to lonnet::ssi.
10989: form - The form hash parameters that guide the interpretation of the resource
10990:
10991: retries - Number of retries allowed before giving up completely.
10992: Returns:
10993: On success, returns the rendered resource identified by the resource parameter.
10994: Side Effects:
10995: The following global variables can be set:
10996: ssi_error - If an unrecoverable error occurred this becomes true.
10997: It is up to the caller to initialize this to false
10998: if desired.
10999: ssi_error_resource - If an unrecoverable error occurred, this is the value
11000: of the resource that could not be rendered by the ssi
11001: call.
11002: ssi_error_message - The error string fetched from the ssi response
11003: in the event of an error.
