+ =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
+    $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  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 <div></div> with a link to re-initialize the course.
+    Should be called whenever the request to instantiate a navmap object fails.
