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. =over 4 =item defaultFormData Returns html hidden inputs used to hold context/default values.

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(). 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. =back =cut
