- Bug 6251.
- Third arg is now a ref to a hash, instead of a hash.

4731: =head1 Bubble sheet grading routines
4732:
4733: For this documentation:
4734:
4735: 'scanline' refers to the full line of characters
4736: from the file that we are parsing that represents one entire sheet
4737:
4738: 'bubble line' refers to the data
4739: representing the line of bubbles that are on the physical bubble sheet
4740:
4741:
4742: The overall process is that a scanned in bubble sheet data is uploaded
4743: into a course. When a user wants to grade, they select a
4744: sequence/folder of resources, a file of bubble sheet info, and pick
4745: one of the predefined configurations for what each scanline looks
4746: like.
4747:
4748: Next each scanline is checked for any errors of either 'missing
4749: bubbles' (it's an error because it may have been mis-scanned
4750: because too light bubbling), 'double bubble' (each bubble line should
4751: have no more that one letter picked), invalid or duplicated CODE,
4752: invalid student/employee ID
4753:
4754: If the CODE option is used that determines the randomization of the
4755: homework problems, either way the student/employee ID is looked up into a
4756: username:domain.
4757:
4758: During the validation phase the instructor can choose to skip scanlines.
4759:
4760: After the validation phase, there are now 3 bubble sheet files
4761:
4762: scantron_original_filename (unmodified original file)
4763: scantron_corrected_filename (file where the corrected information has replaced the original information)
4764: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4765:
4766: Also there is a separate hash nohist_scantrondata that contains extra
4767: correction information that isn't representable in the bubble sheet
4768: file (see &scantron_getfile() for more information)
4769:
4770: After all scanlines are either valid, marked as valid or skipped, then
4771: foreach line foreach problem in the picked sequence, an ssi request is
4772: made that simulates a user submitting their selected letter(s) against
4773: the homework problem.

9343: =head1 NAME
9344:
9345: Apache::grades
9346:
9347: =head1 SYNOPSIS
9348:
9349: Handles the viewing of grades.
9350:
9351: This is part of the LearningOnline Network with CAPA project
9352: described at http://www.lon-capa.org.
9353:
9354: =head1 OVERVIEW
9355:
9356: Do an ssi with retries:
9357: While I'd love to factor out this with the vesrion in lonprintout,
9358: 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
9359: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9360:
9361: At least the logic that drives this has been pulled out into loncommon.
9362:
9363:
9364:
9365: ssi_with_retries - Does the server side include of a resource.
9366: if the ssi call returns an error we'll retry it up to
9367: the number of times requested by the caller.
9368: If we still have a proble, no text is appended to the
9369: output and we set some global variables.
9370: to indicate to the caller an SSI error occurred.
9371: All of this is supposed to deal with the issues described
9372: in LonCAPA BZ 5631 see:
9373: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9374: by informing the user that this happened.
9375:
9376: Parameters:
9377: resource - The resource to include. This is passed directly, without
9378: interpretation to lonnet::ssi.
9379: form - The form hash parameters that guide the interpretation of the resource
9380:
9381: retries - Number of retries allowed before giving up completely.
9382: Returns:
9383: On success, returns the rendered resource identified by the resource parameter.
9384: Side Effects:
9385: The following global variables can be set:
9386: ssi_error - If an unrecoverable error occurred this becomes true.
9387: It is up to the caller to initialize this to false
9388: if desired.
9389: ssi_error_resource - If an unrecoverable error occurred, this is the value
9390: of the resource that could not be rendered by the ssi
9391: call.
9392: ssi_error_message - The error string fetched from the ssi response
9393: in the event of an error.

9404: =item scantron_get_correction() :
9405:
9406: Builds the interface screen to interact with the operator to fix a
9407: specific error condition in a specific scanline
9408:
9409: Arguments:
9410: $r - Apache request object
9411: $i - number of the current scanline
9412: $scan_record - hash ref as returned from &scantron_parse_scanline()
9413: $scan_config - hash ref as returned from &get_scantron_config()
9414: $line - full contents of the current scanline
9415: $error - error condition, valid values are
9416: 'incorrectCODE', 'duplicateCODE',
9417: 'doublebubble', 'missingbubble',
9418: 'duplicateID', 'incorrectID'
9419: $arg - extra information needed
9420: For errors:
9421: - duplicateID - paper number that this studentID was seen before on
9422: - duplicateCODE - array ref of the paper numbers this CODE was
9423: seen on before
9424: - incorrectCODE - current incorrect CODE
9425: - doublebubble - array ref of the bubble lines that have double
9426: bubble errors
9427: - missingbubble - array ref of the bubble lines that have missing
9428: bubble errors
9429:
9430: =item scantron_get_maxbubble() :
9431:
9432: Arguments:
9433: $nav_error - Reference to scalar which is a flag to indicate a
9434: failure to retrieve a navmap object.
9435: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9436: calling routine should trap the error condition and display the warning
9437: found in &navmap_errormsg().
9438:
9439: Returns the maximum number of bubble lines that are expected to
9440: occur. Does this by walking the selected sequence rendering the
9441: resource and then checking &Apache::lonxml::get_problem_counter()
9442: for what the current value of the problem counter is.
9443:
9444: Caches the results to $env{'form.scantron_maxbubble'},
9445: $env{'form.scantron.bubble_lines.n'},
9446: $env{'form.scantron.first_bubble_line.n'} and
9447: $env{"form.scantron.sub_bubblelines.n"}
9448: which are the total number of bubble, lines, the number of bubble
9449: lines for response n and number of the first bubble line for response n,
9450: and a comma separated list of numbers of bubble lines for sub-questions
9451: (for optionresponse, matchresponse, and rankresponse items), for response n.
9452:
9453:
9454: =item scantron_validate_missingbubbles() :

9457: answers that don't have bubbles that have not been verified
9458: to be bubble free.
9459:
9460: =item scantron_process_students() :
9461:
9462: Routine that does the actual grading of the bubble sheet information.
9463:
9464: The parsed scanline hash is added to %env
9465:
9466: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9467: foreach resource , with the form data of
9468:
9469: 'submitted' =>'scantron'
9470: 'grade_target' =>'grade',
9471: 'grade_username'=> username of student
9472: 'grade_domain' => domain of student
9473: 'grade_courseid'=> of course
9474: 'grade_symb' => symb of resource to grade
9475:
9476: This triggers a grading pass. The problem grading code takes care
9477: of converting the bubbled letter information (now in %env) into a
9478: valid submission.
9479:
9480: =item scantron_upload_scantron_data() :

9485:
9486: Adds a provided bubble information data file to the course if user
9487: has the correct privileges to do so.

9489: =item valid_file() :
9490:
9491: Validates that the requested bubble data file exists in the course.
9492:
9493: =item scantron_download_scantron_data() :
9494:
9495: Shows a list of the three internal files (original, corrected,
9496: skipped) for a specific bubble sheet data file that exists in the
9497: course.
9498:
9499: =item scantron_validate_ID() :
9500:
9501: Validates all scanlines in the selected file to not have any
9502: invalid or underspecified student/employee IDs
9503:
9504: =item navmap_errormsg() :
9505:
9506: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9507: Should be called whenever the request to instantiate a navmap object fails.
