Optimized manual grading screen layout:
- Optimized floating of items in submission details option list
- Moved additonal functions (Activity, Change Parameters) directly below corresponding student's name; optimized spacing
- Each student has HTML headline now
- Moved alternating colors from student's name background to left side border
- No additional border needed for each student; adjusted margins and padding
- Better separate footer from rest
- Adding warning style to "...do not save the scores" message
- Added missing &mt() call
- Removed now unused styles (including changes in grades.pm 1.588 and grades.pm 1.590)

4837: =head1 Bubble sheet grading routines
4838:
4839: For this documentation:
4840:
4841: 'scanline' refers to the full line of characters
4842: from the file that we are parsing that represents one entire sheet
4843:
4844: 'bubble line' refers to the data
4845: representing the line of bubbles that are on the physical bubble sheet
4846:
4847:
4848: The overall process is that a scanned in bubble sheet data is uploaded
4849: into a course. When a user wants to grade, they select a
4850: sequence/folder of resources, a file of bubble sheet info, and pick
4851: one of the predefined configurations for what each scanline looks
4852: like.
4853:
4854: Next each scanline is checked for any errors of either 'missing
4855: bubbles' (it's an error because it may have been mis-scanned
4856: because too light bubbling), 'double bubble' (each bubble line should
4857: have no more that one letter picked), invalid or duplicated CODE,
4858: invalid student/employee ID
4859:
4860: If the CODE option is used that determines the randomization of the
4861: homework problems, either way the student/employee ID is looked up into a
4862: username:domain.
4863:
4864: During the validation phase the instructor can choose to skip scanlines.

9459: =head1 NAME
9460:
9461: Apache::grades
9462:
9463: =head1 SYNOPSIS
9464:
9465: Handles the viewing of grades.
9466:
9467: This is part of the LearningOnline Network with CAPA project
9468: described at http://www.lon-capa.org.
9469:
9470: =head1 OVERVIEW
9471:
9472: Do an ssi with retries:
9473: While I'd love to factor out this with the vesrion in lonprintout,
9474: 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
9475: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9476:
9477: At least the logic that drives this has been pulled out into loncommon.
9478:
9479:
9480:
9481: ssi_with_retries - Does the server side include of a resource.
9482: if the ssi call returns an error we'll retry it up to
9483: the number of times requested by the caller.
9484: If we still have a proble, no text is appended to the
9485: output and we set some global variables.
9486: to indicate to the caller an SSI error occurred.
9487: All of this is supposed to deal with the issues described
9488: in LonCAPA BZ 5631 see:
9489: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9490: by informing the user that this happened.
9491:
9492: Parameters:
9493: resource - The resource to include. This is passed directly, without
9494: interpretation to lonnet::ssi.
9495: form - The form hash parameters that guide the interpretation of the resource
9496:
9497: retries - Number of retries allowed before giving up completely.
9498: Returns:
9499: On success, returns the rendered resource identified by the resource parameter.
9500: Side Effects:
9501: The following global variables can be set:
9502: ssi_error - If an unrecoverable error occurred this becomes true.
9503: It is up to the caller to initialize this to false
9504: if desired.
9505: ssi_error_resource - If an unrecoverable error occurred, this is the value
9506: of the resource that could not be rendered by the ssi
9507: call.
9508: ssi_error_message - The error string fetched from the ssi response
9509: in the event of an error.

9520: =item scantron_get_correction() :
9521:
9522: Builds the interface screen to interact with the operator to fix a
9523: specific error condition in a specific scanline
9524:
9525: Arguments:
9526: $r - Apache request object
9527: $i - number of the current scanline
9528: $scan_record - hash ref as returned from &scantron_parse_scanline()
9529: $scan_config - hash ref as returned from &get_scantron_config()
9530: $line - full contents of the current scanline
9531: $error - error condition, valid values are
9532: 'incorrectCODE', 'duplicateCODE',
9533: 'doublebubble', 'missingbubble',
9534: 'duplicateID', 'incorrectID'
9535: $arg - extra information needed
9536: For errors:
9537: - duplicateID - paper number that this studentID was seen before on
9538: - duplicateCODE - array ref of the paper numbers this CODE was
9539: seen on before
9540: - incorrectCODE - current incorrect CODE
9541: - doublebubble - array ref of the bubble lines that have double
9542: bubble errors

9544: bubble errors

9546: =item scantron_get_maxbubble() :
9547:
9548: Arguments:
9549: $nav_error - Reference to scalar which is a flag to indicate a
9550: failure to retrieve a navmap object.
9551: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9552: calling routine should trap the error condition and display the warning
9553: found in &navmap_errormsg().
9554:
9555: Returns the maximum number of bubble lines that are expected to
9556: occur. Does this by walking the selected sequence rendering the
9557: resource and then checking &Apache::lonxml::get_problem_counter()
9558: for what the current value of the problem counter is.
9559:
9560: Caches the results to $env{'form.scantron_maxbubble'},
9561: $env{'form.scantron.bubble_lines.n'},
9562: $env{'form.scantron.first_bubble_line.n'} and
9563: $env{"form.scantron.sub_bubblelines.n"}
9564: which are the total number of bubble, lines, the number of bubble
9565: lines for response n and number of the first bubble line for response n,
9566: and a comma separated list of numbers of bubble lines for sub-questions
9567: (for optionresponse, matchresponse, and rankresponse items), for response n.

9579:
9580: The parsed scanline hash is added to %env
9581:
9582: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9583: foreach resource , with the form data of
9584:
9585: 'submitted' =>'scantron'
9586: 'grade_target' =>'grade',
9587: 'grade_username'=> username of student
9588: 'grade_domain' => domain of student
9589: 'grade_courseid'=> of course
9590: 'grade_symb' => symb of resource to grade
9591:
9592: This triggers a grading pass. The problem grading code takes care
