+=head1 Bubble sheet grading routines
+
+ For this documentation:
+
+ 'scanline' refers to the full line of characters
+ from the file that we are parsing that represents one entire sheet
+
+ '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.

+ (see scantron_getfile for more information)
+ just_header - True if should not process question answers but only
+ the stuff to the left of the answers.
+ randomorder - True if randomorder in use
+ randompick - True if randompick in use
+ sequence - Exam folder URL
+ master_seq - Ref to array containing symbs in exam folder
+ symb_to_resource - Ref to hash of symbs for resources in exam folder
+ (corresponding values are resource objects)
+ partids_by_symb - Ref to hash of symb -> array ref of partIDs
+ orderedforcode - Ref to hash of arrays. keys are CODEs and values
+ are refs to an array of resource objects, ordered
+ according to order used for CODE, when randomorder
+ and or randompick are in use.
+ respnumlookup - Ref to hash mapping question numbers in bubble lines
+ for current line to question number used for same question
+ in "Master Sequence" (as seen by Course Coordinator).
+ startline - Ref 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.
+ totalref - Ref of scalar used to score total number of bubble
+ lines needed for responses in a scan line (used when
+ randompick in use.
+
+ Returns:
+ Hash containing the result of parsing the scanline
+
+ Keys are all proceeded by the string 'scantron.'
+
+ CODE - the CODE in use for this scanline
+ useCODE - 1 if the CODE is invalid but it usage has been forced
+ by the operator
+ CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
+ CODEs were selected, but the usage has been
+ forced by the operator
+ ID - student/employee ID
+ PaperID - if used, the ID number printed on the sheet when the
+ paper was scanned
+ FirstName - first name from the sheet
+ LastName - last name from the sheet
+
+ if just_header was not true these key may also exist
+
+ missingerror - a list of bubble ranges that are considered to be answers
+ to a single question that don't have any bubbles filled in.
+ Of the form questionnumber:firstbubblenumber:count.
+ doubleerror - a list of bubble ranges that are considered to be answers
+ to a single question that have more than one bubble filled in.
+ Of the form questionnumber::firstbubblenumber:count
+
+ In the above, count is the number of bubble responses in the
+ input line needed to represent the possible answers to the question.
+ e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
+ per line would have count = 2.
+
+ maxquest - the number of the last bubble line that was parsed
+
+ ( starts at 1)
+ .answer - zero or more letters representing the selected
+ letters from the scanline for the bubble line
+ .
+ if blank there was either no bubble or there where
+ multiple bubbles, (consult the keys missingerror and
+ doubleerror if this is an error condition)

+ or code-based randompick and/or randomorder.
+
+ Implicit inputs:
+ %bubble_lines_per_response - Starting line numbers for each question.

+=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 vesrion 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

+
+=head1 SUBROUTINES
+
+=over
+
+=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 (or a sub-folder) has randomorder set
+ $randompick - True if exam folder (or a sub-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.
+
