4790: =head1 Bubble sheet grading routines
4791:
4792: For this documentation:
4793:
4794: 'scanline' refers to the full line of characters
4795: from the file that we are parsing that represents one entire sheet
4796:
4797: 'bubble line' refers to the data
4798: representing the line of bubbles that are on the physical bubble sheet
4799:
4800:
4801: The overall process is that a scanned in bubble sheet data is uploaded
4802: into a course. When a user wants to grade, they select a
4803: sequence/folder of resources, a file of bubble sheet info, and pick
4804: one of the predefined configurations for what each scanline looks
4805: like.
4806:
4807: Next each scanline is checked for any errors of either 'missing
4808: bubbles' (it's an error because it may have been mis-scanned
4809: because too light bubbling), 'double bubble' (each bubble line should
4810: have no more that one letter picked), invalid or duplicated CODE,
4811: invalid student/employee ID
4812:
4813: If the CODE option is used that determines the randomization of the
4814: homework problems, either way the student/employee ID is looked up into a
4815: username:domain.
4816:
4817: During the validation phase the instructor can choose to skip scanlines.
4818:
4819: After the validation phase, there are now 3 bubble sheet files
4820:
4821: scantron_original_filename (unmodified original file)
4822: scantron_corrected_filename (file where the corrected information has replaced the original information)
4823: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4824:
4825: Also there is a separate hash nohist_scantrondata that contains extra
4826: correction information that isn't representable in the bubble sheet
4827: file (see &scantron_getfile() for more information)
4828:
4829: After all scanlines are either valid, marked as valid or skipped, then
4830: foreach line foreach problem in the picked sequence, an ssi request is
4831: made that simulates a user submitting their selected letter(s) against
4832: the homework problem.

9386: =head1 NAME
9387:
9388: Apache::grades
9389:
9390: =head1 SYNOPSIS
9391:
9392: Handles the viewing of grades.
9393:
9394: This is part of the LearningOnline Network with CAPA project
9395: described at http://www.lon-capa.org.
9396:
9397: =head1 OVERVIEW
9398:
9399: Do an ssi with retries:
9400: While I'd love to factor out this with the vesrion in lonprintout,
9401: 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
9402: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9403:
9404: At least the logic that drives this has been pulled out into loncommon.
9405:
9406:
9407:
9408: ssi_with_retries - Does the server side include of a resource.
9409: if the ssi call returns an error we'll retry it up to
9410: the number of times requested by the caller.
9411: If we still have a proble, no text is appended to the
9412: output and we set some global variables.
9413: to indicate to the caller an SSI error occurred.
9414: All of this is supposed to deal with the issues described
9415: in LonCAPA BZ 5631 see:
9416: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9417: by informing the user that this happened.
9418:
9419: Parameters:
9420: resource - The resource to include. This is passed directly, without
9421: interpretation to lonnet::ssi.
9422: form - The form hash parameters that guide the interpretation of the resource
9423:
9424: retries - Number of retries allowed before giving up completely.
9425: Returns:
9426: On success, returns the rendered resource identified by the resource parameter.
9427: Side Effects:
9428: The following global variables can be set:
9429: ssi_error - If an unrecoverable error occurred this becomes true.
9430: It is up to the caller to initialize this to false
9431: if desired.
9432: ssi_error_resource - If an unrecoverable error occurred, this is the value
9433: of the resource that could not be rendered by the ssi
9434: call.
9435: ssi_error_message - The error string fetched from the ssi response
9436: in the event of an error.

9479: calling routine should trap the error condition and display the warning
9480: found in &navmap_errormsg().
9481:
9482: Returns the maximum number of bubble lines that are expected to
9483: occur. Does this by walking the selected sequence rendering the
9484: resource and then checking &Apache::lonxml::get_problem_counter()
9485: for what the current value of the problem counter is.

9489: $env{'form.scantron.first_bubble_line.n'} and
9490: $env{"form.scantron.sub_bubblelines.n"}
9491: which are the total number of bubble, lines, the number of bubble
9492: lines for response n and number of the first bubble line for response n,
9493: and a comma separated list of numbers of bubble lines for sub-questions
9494: (for optionresponse, matchresponse, and rankresponse items), for response n.

9506:
9507: The parsed scanline hash is added to %env
9508:
9509: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()

9516: 'grade_courseid'=> of course
9517: 'grade_symb' => symb of resource to grade
9518:
9519: This triggers a grading pass. The problem grading code takes care
9520: of converting the bubbled letter information (now in %env) into a
9521: valid submission.
