+
+ 'bubble line' refers to the data
+ representing the line of bubbles that are on the physical bubblesheet
+
+
+The overall process is that a scanned in bubblesheet data is uploaded
+into a course. When a user wants to grade, they select a
+sequence/folder of resources, a file of bubblesheet info, and pick
+one of the predefined configurations for what each scanline looks
+like.
+
+Next each scanline is checked for any errors of either 'missing
+bubbles' (it's an error because it may have been mis-scanned
+because too light bubbling), 'double bubble' (each bubble line should
+have no more than one letter picked), invalid or duplicated CODE,
+invalid student/employee ID
+
+If the CODE option is used that determines the randomization of the
+homework problems, either way the student/employee ID is looked up into a
+username:domain.
+
+During the validation phase the instructor can choose to skip scanlines.
+
+After the validation phase, there are now 3 bubblesheet files
+
+ scantron_original_filename (unmodified original file)
+ scantron_corrected_filename (file where the corrected information has replaced the original information)
+ scantron_skipped_filename (contains the exact text of scanlines that where skipped)
+
+Also there is a separate hash nohist_scantrondata that contains extra
+correction information that isn't representable in the bubblesheet
+file (see &scantron_getfile() for more information)
+
+After all scanlines are either valid, marked as valid or skipped, then
+foreach line foreach problem in the picked sequence, an ssi request is
+made that simulates a user submitting their selected letter(s) against
+the homework problem.

+ $scan_record - Reference to the hash that has the the parsed scanlines.
+ $error - Type of error

+ $respnumlookup - Reference to HASH mapping question numbers in bubble lines
+ for current line to question number used for same question
+ in "Master Seqence" (as seen by Course Coordinator).
+ $startline - Reference to hash where key is question number (0 is first)
+ and value is number of first bubble line for current student
+ or code-based randompick and/or randomorder.
+
+
+ Implicit inputs:
+ %bubble_lines_per_response - Starting line numbers for each question.
+ Numbered from 0 (but question numbers are from
+ 1.
+ %first_bubble_line - Starting bubble line for each question.
+ %subdivided_bubble_lines - optionresponse, matchresponse and rankresponse
+ type problems render as separate sub-questions,
+ in exam mode. This hash contains a
+ comma-separated list of the lines per
+ sub-question.
+ %responsetype_per_response - essayresponse, formularesponse,

+ and organicresponse type problem parts can have
+ multiple lines per response if the weight
+ assigned exceeds 10. In this case, only
+ one bubble per line is permitted, but more
+ than one line might contain bubbles, e.g.
+ bubbling of: line 1 - J, line 2 - J,

+=head1 NAME
+
+Apache::grades
+
+=head1 SYNOPSIS
+
+Handles the viewing of grades.
+
+This is part of the LearningOnline Network with CAPA project
+described at http://www.lon-capa.org.
+
+=head1 OVERVIEW
+
+Do an ssi with retries:
+While I'd love to factor out this with the version in lonprintout,
+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
+I'm not quite ready to invent (e.g. an ssi_with_retry object).
+
+At least the logic that drives this has been pulled out into loncommon.
+
+
+
+ssi_with_retries - Does the server side include of a resource.
+ if the ssi call returns an error we'll retry it up to
+ the number of times requested by the caller.
+ If we still have a problem, no text is appended to the
+ output and we set some global variables.
+ to indicate to the caller an SSI error occurred.
+ All of this is supposed to deal with the issues described
+ in LON-CAPA BZ 5631 see:
+ http://bugs.lon-capa.org/show_bug.cgi?id=5631
+ by informing the user that this happened.
+
+Parameters:
+ resource - The resource to include. This is passed directly, without
+ interpretation to lonnet::ssi.
+ form - The form hash parameters that guide the interpretation of the resource
+
+ retries - Number of retries allowed before giving up completely.
+Returns:
+ On success, returns the rendered resource identified by the resource parameter.
+Side Effects:
+ The following global variables can be set:
+ ssi_error - If an unrecoverable error occurred this becomes true.
+ It is up to the caller to initialize this to false
+ if desired.
+ ssi_error_resource - If an unrecoverable error occurred, this is the value
+ of the resource that could not be rendered by the ssi
+ call.
+ ssi_error_message - The error string fetched from the ssi response
+ in the event of an error.
+

+=head1 HANDLER SUBROUTINE
+
+ssi_with_retries()
+
+=head1 SUBROUTINES
+
+=over
+
+=head1 Routines to display previous version of a Task for a specific student
+
+Tasks are graded pass/fail. Students who have yet to pass a particular Task
+can receive another opportunity. Access to tasks is slot-based. If a slot
+requires a proctor to check-in the student, a new version of the Task will
+be created when the student is checked in to the new opportunity.
+
+If a particular student has tried two or more versions of a particular task,
+the submission screen provides a user with vgr privileges (e.g., a Course
+Coordinator) the ability to display a previous version worked on by the
+student. By default, the current version is displayed. If a previous version
+has been selected for display, submission data are only shown that pertain
+to that particular version, and the interface to submit grades is not shown.
+
+=over 4
+
+=item show_previous_task_version()
+
+Displays a specified version of a student's Task, as the student sees it.
+
+Inputs: 2
+ request - request object
+ symb - unique symb for current instance of resource
+
+Output: None.
+
+Side Effects: calls &show_problem() to print version of Task, with
+ version contained in form item: $env{'form.previousversion'}
+
+=item choose_task_version_form()
+
+Displays a web form used to select which version of a student's view of a
+Task should be displayed. Either launches a pop-up window, or replaces
+content in existing pop-up, or replaces page in main window.
+
+Inputs: 4
+ symb - unique symb for current instance of resource
+ uname - username of student
+ udom - domain of student
+ nomenu - 1 if display is in a pop-up window, and hence no menu
+ breadcrumbs etc., are displayed
+
+Output: 4
+ current - student's current version
+ displayed - student's version being displayed
+ result - scalar containing HTML for web form used to switch to
+ a different version (or a link to close window, if pop-up).
+ js - javascript for processing selection in versions web form
+
+Side Effects: None.
+
+=item previous_display_javascript()
+
+Inputs: 2
+ nomenu - 1 if display is in a pop-up window, and hence no menu
+ breadcrumbs etc., are displayed.
+ current - student's current version number.
+
+Output: 1
+ js - javascript for processing selection in versions web form.
+
+Side Effects: None.

+=head1 Routines to process bubblesheet data.
+
+=over 4
+
+=item scantron_get_correction() :
+
+ Builds the interface screen to interact with the operator to fix a
+ specific error condition in a specific scanline
+
+ Arguments:
+ $r - Apache request object
+ $i - number of the current scanline
+ $scan_record - hash ref as returned from &scantron_parse_scanline()
+ $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
+ $line - full contents of the current scanline
+ $error - error condition, valid values are
+ 'incorrectCODE', 'duplicateCODE',
+ 'doublebubble', 'missingbubble',
+ 'duplicateID', 'incorrectID'
+ $arg - extra information needed
+ For errors:
+ - duplicateID - paper number that this studentID was seen before on
+ - duplicateCODE - array ref of the paper numbers this CODE was
+ seen on before
+ - incorrectCODE - current incorrect CODE
+ - doublebubble - array ref of the bubble lines that have double
+ bubble errors
+ - missingbubble - array ref of the bubble lines that have missing
+ bubble errors
+
+ $randomorder - True if exam folder has randomorder set
+ $randompick - True if exam folder has randompick set
+ $respnumlookup - Reference to HASH mapping question numbers in bubble lines
+ for current line to question number used for same question
+ in "Master Seqence" (as seen by Course Coordinator).
+ $startline - Reference to hash where key is question number (0 is first)
+ and value is number of first bubble line for current student
+ or code-based randompick and/or randomorder.
+
+
+
+=item scantron_get_maxbubble() :
+
+ Arguments:
+ $nav_error - Reference to scalar which is a flag to indicate a
+ failure to retrieve a navmap object.
+ if $nav_error is set to 1 by scantron_get_maxbubble(), the
+ calling routine should trap the error condition and display the warning
+ found in &navmap_errormsg().
+
+ $scantron_config - Reference to bubblesheet format configuration hash.
+
+ Returns the maximum number of bubble lines that are expected to
+ occur. Does this by walking the selected sequence rendering the
+ resource and then checking &Apache::lonxml::get_problem_counter()
+ for what the current value of the problem counter is.
+
+ Caches the results to $env{'form.scantron_maxbubble'},
+ $env{'form.scantron.bubble_lines.n'},
+ $env{'form.scantron.first_bubble_line.n'} and
+ $env{"form.scantron.sub_bubblelines.n"}
+ which are the total number of bubble lines, the number of bubble
+ lines for response n and number of the first bubble line for response n,
+ and a comma separated list of numbers of bubble lines for sub-questions
+ (for optionresponse, matchresponse, and rankresponse items), for response n.
+
+
+=item scantron_validate_missingbubbles() :
+
+ Validates all scanlines in the selected file to not have any
+ answers that don't have bubbles that have not been verified
+ to be bubble free.
+
+=item scantron_process_students() :
+
+ Routine that does the actual grading of the bubblesheet information.
+
+ The parsed scanline hash is added to %env
+
+ Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
+ foreach resource , with the form data of
+
+ 'submitted' =>'scantron'
+ 'grade_target' =>'grade',
+ 'grade_username'=> username of student
+ 'grade_domain' => domain of student
+ 'grade_courseid'=> of course
+ 'grade_symb' => symb of resource to grade
+
+ This triggers a grading pass. The problem grading code takes care
+ of converting the bubbled letter information (now in %env) into a
+ valid submission.
+
+=item scantron_upload_scantron_data() :
+
+ Creates the screen for adding a new bubblesheet data file to a course.
+
+=item scantron_upload_scantron_data_save() :
+
+ Adds a provided bubble information data file to the course if user
+ has the correct privileges to do so.
+
+= item scantron_upload_delete() :
+
+ Deletes a previously uploaded bubble information data file, if user
+ was the one who uploaded the file, and has the privileges to do so.
+
+=item valid_file() :
+
+ Validates that the requested bubble data file exists in the course.
+
+=item scantron_download_scantron_data() :
+
+ Shows a list of the three internal files (original, corrected,
+ skipped) for a specific bubblesheet data file that exists in the
+ course.
+
+=item scantron_validate_ID() :
+
+ Validates all scanlines in the selected file to not have any
+ invalid or underspecified student/employee IDs
+
+=item navmap_errormsg() :
+
+ Returns HTML mark-up inside a
with a link to re-initialize the course.
+ Should be called whenever the request to instantiate a navmap object fails.
