5214:
1.424 albertel 5215: For this documentation:
5216:
5217: 'scanline' refers to the full line of characters
5218: from the file that we are parsing that represents one entire sheet
5219:
5220: 'bubble line' refers to the data
1.596.2.6 raeburn 5221: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5222:
5223:
1.596.2.6 raeburn 5224: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5225: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5226: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5227: one of the predefined configurations for what each scanline looks
5228: like.
5229:
5230: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5231: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5232: because too light bubbling), 'double bubble' (each bubble line should
1.596.2.12.2. 0(raebur 5233:3): have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5234: invalid student/employee ID
1.424 albertel 5235:
5236: If the CODE option is used that determines the randomization of the
1.556 weissno 5237: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5238: username:domain.
5239:
5240: During the validation phase the instructor can choose to skip scanlines.
5241:
1.596.2.6 raeburn 5242: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5243:
5244: scantron_original_filename (unmodified original file)
5245: scantron_corrected_filename (file where the corrected information has replaced the original information)
5246: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5247:
5248: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5249: correction information that isn't representable in the bubblesheet
1.424 albertel 5250: file (see &scantron_getfile() for more information)
5251:
5252: After all scanlines are either valid, marked as valid or skipped, then
5253: foreach line foreach problem in the picked sequence, an ssi request is
5254: made that simulates a user submitting their selected letter(s) against
5255: the homework problem.

1.423 albertel 6051: Returns:
6052: Hash containing the result of parsing the scanline
6053:
6054: Keys are all proceeded by the string 'scantron.'
6055:
6056: CODE - the CODE in use for this scanline
6057: useCODE - 1 if the CODE is invalid but it usage has been forced
6058: by the operator
6059: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
6060: CODEs were selected, but the usage has been
6061: forced by the operator
1.556 weissno 6062: ID - student/employee ID

6074: to a single question that have more than one bubble filled in.
6075: Of the form questionnumber::firstbubblenumber:count
6076:
6077: In the above, count is the number of bubble responses in the
6078: input line needed to represent the possible answers to the question.
6079: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
6080: per line would have count = 2.

10525:
10526: Apache::grades
10527:
10528: =head1 SYNOPSIS
10529:
10530: Handles the viewing of grades.
10531:
10532: This is part of the LearningOnline Network with CAPA project
10533: described at http://www.lon-capa.org.
10534:
10535: =head1 OVERVIEW
10536:
10537: Do an ssi with retries:
10538: While I'd love to factor out this with the vesrion in lonprintout,
10539: 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
10540: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10541:
10542: At least the logic that drives this has been pulled out into loncommon.
10543:
10544:
10545:
10546: ssi_with_retries - Does the server side include of a resource.
10547: if the ssi call returns an error we'll retry it up to
10548: the number of times requested by the caller.
10549: If we still have a proble, no text is appended to the
10550: output and we set some global variables.
10551: to indicate to the caller an SSI error occurred.
10552: All of this is supposed to deal with the issues described
10553: in LonCAPA BZ 5631 see:
10554: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10555: by informing the user that this happened.
10556:
10557: Parameters:
10558: resource - The resource to include. This is passed directly, without
10559: interpretation to lonnet::ssi.
10560: form - The form hash parameters that guide the interpretation of the resource
10561:
10562: retries - Number of retries allowed before giving up completely.
10563: Returns:
10564: On success, returns the rendered resource identified by the resource parameter.
10565: Side Effects:
10566: The following global variables can be set:
10567: ssi_error - If an unrecoverable error occurred this becomes true.
10568: It is up to the caller to initialize this to false
10569: if desired.
10570: ssi_error_resource - If an unrecoverable error occurred, this is the value
10571: of the resource that could not be rendered by the ssi
10572: call.
10573: ssi_error_message - The error string fetched from the ssi response
10574: in the event of an error.
