=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 that 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.

to signal a bubble was chosen in the positional setup, or
the string 'letter' if the letter of the chosen bubble is
in the final, or 'number' if a number representing the
chosen bubble is in the file (1->A 0->J)
Qoff - the character used to represent that a bubble was
left blank

sheet scanned the column that this ID number starts in
PaperIDlength - number of columns that comprise the unique ID number
for the sheet of paper
FirstName - column that the first name starts in
FirstNameLength - number of columns that the first name spans

=item scantron_parse_scanline
Decodes a scanline from the selected scantron file
Arguments:
line - The text of the scantron file line to process
whichline - Line number
scantron_config - Hash describing the format of the scantron lines.
scan_data - Hash of extra information about the scanline
(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.
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
(<number> starts at 1)
<number>.answer - zero or more letters representing the selected
letters from the scanline for the bubble line
<number>.
if blank there was either no bubble or there where
multiple bubbles, (consult the keys missingerror and
doubleerror if this is an error condition)

$bubline refers to the specific bubble line element and the aspects
refers to that specific bubble line element)
$number.user - username:domain to use
$number.CODE_ignore_dup
- ignore the duplicate CODE error
$number.useCODE
- use the CODE in the scanline as is
$number.no_bubble.$bubline
- it is valid that there is no bubbled in bubble
at $number $bubline
remember_skipping
- a frozen hash containing keys of $number and values
of either
1 - we are on a 'do skipped records pass' and plan
on processing this line
2 - we are on a 'do skipped records pass' and this
scanline has been marked to skip yet again

Prompts for a potentially multiline correction to the

for multi and missing bubble cases).
Arguments:
$r - Apache request object.
$question - The question number to prompt for.
$scan_config - The scantron file configuration hash.
$scan_record - Reference to the hash that has the the parsed scanlines.
$error - Type of error
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,
stringresponse, imageresponse, reactionresponse,
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,
line 3 - B would assign 22 points.

=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 proble, 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 LonCAPA 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
=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 &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
=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

=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.
