- Change to way lonnet::dirlist() reports an error condition (i.e., no_host,
con_lost, no_such_dir, empty etc.) when retrieving directory list information
with ls3, ls2 or ls.
- error is passed as second item in a pair of return values.
- first item in return values is a reference to an array of actual files.

4839: =head1 Bubble sheet grading routines
4840:
4841: For this documentation:
4842:
4843: 'scanline' refers to the full line of characters
4844: from the file that we are parsing that represents one entire sheet
4845:
4846: 'bubble line' refers to the data
4847: representing the line of bubbles that are on the physical bubblesheet
4848:
4849:
4850: The overall process is that a scanned in bubblesheet data is uploaded
4851: into a course. When a user wants to grade, they select a
4852: sequence/folder of resources, a file of bubblesheet info, and pick
4853: one of the predefined configurations for what each scanline looks
4854: like.
4855:
4856: Next each scanline is checked for any errors of either 'missing
4857: bubbles' (it's an error because it may have been mis-scanned
4858: because too light bubbling), 'double bubble' (each bubble line should
4859: have no more that one letter picked), invalid or duplicated CODE,
4860: invalid student/employee ID
4861:
4862: If the CODE option is used that determines the randomization of the
4863: homework problems, either way the student/employee ID is looked up into a
4864: username:domain.
4865:
4866: During the validation phase the instructor can choose to skip scanlines.
4867:
4868: After the validation phase, there are now 3 bubblesheet files
4869:
4870: scantron_original_filename (unmodified original file)
4871: scantron_corrected_filename (file where the corrected information has replaced the original information)
4872: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4873:
4874: Also there is a separate hash nohist_scantrondata that contains extra
4875: correction information that isn't representable in the bubblesheet
4876: file (see &scantron_getfile() for more information)
4877:
4878: After all scanlines are either valid, marked as valid or skipped, then
4879: foreach line foreach problem in the picked sequence, an ssi request is
4880: made that simulates a user submitting their selected letter(s) against
4881: the homework problem.

9532: =head1 NAME
9533:
9534: Apache::grades
9535:
9536: =head1 SYNOPSIS
9537:
9538: Handles the viewing of grades.
9539:
9540: This is part of the LearningOnline Network with CAPA project
9541: described at http://www.lon-capa.org.
9542:
9543: =head1 OVERVIEW
9544:
9545: Do an ssi with retries:
9546: While I'd love to factor out this with the vesrion in lonprintout,
9547: 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
9548: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9549:
9550: At least the logic that drives this has been pulled out into loncommon.
9551:
9552:
9553:
9554: ssi_with_retries - Does the server side include of a resource.
9555: if the ssi call returns an error we'll retry it up to
9556: the number of times requested by the caller.
9557: If we still have a proble, no text is appended to the
9558: output and we set some global variables.
9559: to indicate to the caller an SSI error occurred.
9560: All of this is supposed to deal with the issues described
9561: in LonCAPA BZ 5631 see:
9562: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9563: by informing the user that this happened.
9564:
9565: Parameters:
9566: resource - The resource to include. This is passed directly, without
9567: interpretation to lonnet::ssi.
9568: form - The form hash parameters that guide the interpretation of the resource
9569:
9570: retries - Number of retries allowed before giving up completely.
9571: Returns:
9572: On success, returns the rendered resource identified by the resource parameter.
9573: Side Effects:
9574: The following global variables can be set:
9575: ssi_error - If an unrecoverable error occurred this becomes true.
9576: It is up to the caller to initialize this to false
9577: if desired.
9578: ssi_error_resource - If an unrecoverable error occurred, this is the value
9579: of the resource that could not be rendered by the ssi
9580: call.
9581: ssi_error_message - The error string fetched from the ssi response
9582: in the event of an error.

9592:
9593: =item scantron_get_correction() :
9594:
9595: Builds the interface screen to interact with the operator to fix a
9596: specific error condition in a specific scanline
9597:
9598: Arguments:
9599: $r - Apache request object
9600: $i - number of the current scanline
9601: $scan_record - hash ref as returned from &scantron_parse_scanline()
9602: $scan_config - hash ref as returned from &get_scantron_config()
9603: $line - full contents of the current scanline
9604: $error - error condition, valid values are
9605: 'incorrectCODE', 'duplicateCODE',
9606: 'doublebubble', 'missingbubble',
9607: 'duplicateID', 'incorrectID'
9608: $arg - extra information needed
9609: For errors:
9610: - duplicateID - paper number that this studentID was seen before on
9611: - duplicateCODE - array ref of the paper numbers this CODE was
9612: seen on before
9613: - incorrectCODE - current incorrect CODE
9614: - doublebubble - array ref of the bubble lines that have double
9615: bubble errors
9616: - missingbubble - array ref of the bubble lines that have missing
9617: bubble errors
9618:
9619: =item scantron_get_maxbubble() :
9620:
9621: Arguments:
9622: $nav_error - Reference to scalar which is a flag to indicate a
9623: failure to retrieve a navmap object.
9624: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9625: calling routine should trap the error condition and display the warning
9626: found in &navmap_errormsg().
9627:
9628: $scantron_config - Reference to bubblesheet format configuration hash.
9629:
9630: Returns the maximum number of bubble lines that are expected to
9631: occur. Does this by walking the selected sequence rendering the
9632: resource and then checking &Apache::lonxml::get_problem_counter()
9633: for what the current value of the problem counter is.
9634:
9635: Caches the results to $env{'form.scantron_maxbubble'},
9636: $env{'form.scantron.bubble_lines.n'},
9637: $env{'form.scantron.first_bubble_line.n'} and
9638: $env{"form.scantron.sub_bubblelines.n"}
9639: which are the total number of bubble, lines, the number of bubble
9640: lines for response n and number of the first bubble line for response n,
9641: and a comma separated list of numbers of bubble lines for sub-questions
9642: (for optionresponse, matchresponse, and rankresponse items), for response n.
9643:
9644:
9645: =item scantron_validate_missingbubbles() :
9646:
9647: Validates all scanlines in the selected file to not have any
9648: answers that don't have bubbles that have not been verified
9649: to be bubble free.
9650:
9651: =item scantron_process_students() :
9652:
9653: Routine that does the actual grading of the bubblesheet information.
9654:
9655: The parsed scanline hash is added to %env
9656:
9657: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9658: foreach resource , with the form data of
9659:
9660: 'submitted' =>'scantron'
9661: 'grade_target' =>'grade',
9662: 'grade_username'=> username of student
9663: 'grade_domain' => domain of student
9664: 'grade_courseid'=> of course
9665: 'grade_symb' => symb of resource to grade
9666:
9667: This triggers a grading pass. The problem grading code takes care
9668: of converting the bubbled letter information (now in %env) into a
9669: valid submission.
9670:
9671: =item scantron_upload_scantron_data() :
9672:
9673: Creates the screen for adding a new bubblesheet data file to a course.
9674:
9675: =item scantron_upload_scantron_data_save() :
9676:
9677: Adds a provided bubble information data file to the course if user
9678: has the correct privileges to do so.
9679:
9680: =item valid_file() :
9681:
9682: Validates that the requested bubble data file exists in the course.
9683:
9684: =item scantron_download_scantron_data() :
9685:
9686: Shows a list of the three internal files (original, corrected,
9687: skipped) for a specific bubblesheet data file that exists in the
9688: course.
9689:
9690: =item scantron_validate_ID() :
9691:
9692: Validates all scanlines in the selected file to not have any
9693: invalid or underspecified student/employee IDs
9694:
9695: =item navmap_errormsg() :
9696:
9697: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9698: Should be called whenever the request to instantiate a navmap object fails.
