Efficiency changes.
- Scantron grading and Standalone verification.
- Eliminate calls to &scantron_partids_tograde() to get responseIDs for each student if the resource does not contain randomlist.
- Use partIDs/responseIDs retrieved (once) for current grader.
- Additional hash to cache.
%analyze_cache_formkeys - additional form items used when record stored in %analyze_cache for a given key.
- Additional arg for &get_analyze().
$add_to_hash - can be a ref to a HASH of additional form items to include in the ssi call.
- &scantron_partids_tograde() includes 'check_parts_withrandomlist' as additional arg
- so structuretags::start_randomlist() will add parts to $Apache::lonhomework::analyze{'parts_withrandomlist'} an arrayref if the resource contains a randomlist.

4692: =head1 Bubble sheet grading routines
4693:
4694: For this documentation:
4695:
4696: 'scanline' refers to the full line of characters
4697: from the file that we are parsing that represents one entire sheet
4698:
4699: 'bubble line' refers to the data
4700: representing the line of bubbles that are on the physical bubble sheet
4701:
4702:
4703: The overall process is that a scanned in bubble sheet data is uploaded
4704: into a course. When a user wants to grade, they select a
4705: sequence/folder of resources, a file of bubble sheet info, and pick
4706: one of the predefined configurations for what each scanline looks
4707: like.
4708:
4709: Next each scanline is checked for any errors of either 'missing
4710: bubbles' (it's an error because it may have been mis-scanned
4711: because too light bubbling), 'double bubble' (each bubble line should
4712: have no more that one letter picked), invalid or duplicated CODE,
4713: invalid student/employee ID
4714:
4715: If the CODE option is used that determines the randomization of the
4716: homework problems, either way the student/employee ID is looked up into a
4717: username:domain.
4718:
4719: During the validation phase the instructor can choose to skip scanlines.
4720:
4721: After the validation phase, there are now 3 bubble sheet files
4722:
4723: scantron_original_filename (unmodified original file)
4724: scantron_corrected_filename (file where the corrected information has replaced the original information)
4725: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4726:
4727: Also there is a separate hash nohist_scantrondata that contains extra
4728: correction information that isn't representable in the bubble sheet
4729: file (see &scantron_getfile() for more information)
4730:
4731: After all scanlines are either valid, marked as valid or skipped, then
4732: foreach line foreach problem in the picked sequence, an ssi request is
4733: made that simulates a user submitting their selected letter(s) against
4734: the homework problem.

9114: =head1 NAME
9115:
9116: Apache::grades
9117:
9118: =head1 SYNOPSIS
9119:
9120: Handles the viewing of grades.
9121:
9122: This is part of the LearningOnline Network with CAPA project
9123: described at http://www.lon-capa.org.
9124:
9125: =head1 OVERVIEW
9126:
9127: Do an ssi with retries:
9128: While I'd love to factor out this with the vesrion in lonprintout,
9129: 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
9130: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9131:
9132: At least the logic that drives this has been pulled out into loncommon.
9133:
9134:
9135:
9136: ssi_with_retries - Does the server side include of a resource.
9137: if the ssi call returns an error we'll retry it up to
9138: the number of times requested by the caller.
9139: If we still have a proble, no text is appended to the
9140: output and we set some global variables.
9141: to indicate to the caller an SSI error occurred.
9142: All of this is supposed to deal with the issues described
9143: in LonCAPA BZ 5631 see:
9144: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9145: by informing the user that this happened.
9146:
9147: Parameters:
9148: resource - The resource to include. This is passed directly, without
9149: interpretation to lonnet::ssi.
9150: form - The form hash parameters that guide the interpretation of the resource
9151:
9152: retries - Number of retries allowed before giving up completely.
9153: Returns:
9154: On success, returns the rendered resource identified by the resource parameter.
9155: Side Effects:
9156: The following global variables can be set:
9157: ssi_error - If an unrecoverable error occurred this becomes true.
9158: It is up to the caller to initialize this to false
9159: if desired.
9160: ssi_error_resource - If an unrecoverable error occurred, this is the value
9161: of the resource that could not be rendered by the ssi
9162: call.
9163: ssi_error_message - The error string fetched from the ssi response
9164: in the event of an error.

9175: =item scantron_get_correction() :
9176:
9177: Builds the interface screen to interact with the operator to fix a
9178: specific error condition in a specific scanline
9179:
9180: Arguments:
9181: $r - Apache request object
9182: $i - number of the current scanline
9183: $scan_record - hash ref as returned from &scantron_parse_scanline()
9184: $scan_config - hash ref as returned from &get_scantron_config()
9185: $line - full contents of the current scanline
9186: $error - error condition, valid values are
9187: 'incorrectCODE', 'duplicateCODE',
9188: 'doublebubble', 'missingbubble',
9189: 'duplicateID', 'incorrectID'
9190: $arg - extra information needed
9191: For errors:
9192: - duplicateID - paper number that this studentID was seen before on
9193: - duplicateCODE - array ref of the paper numbers this CODE was
9194: seen on before
9195: - incorrectCODE - current incorrect CODE
9196: - doublebubble - array ref of the bubble lines that have double
9197: bubble errors
9198: - missingbubble - array ref of the bubble lines that have missing
9199: bubble errors
9200:
9201: =item scantron_get_maxbubble() :
9202:
9203: Returns the maximum number of bubble lines that are expected to
9204: occur. Does this by walking the selected sequence rendering the
9205: resource and then checking &Apache::lonxml::get_problem_counter()
9206: for what the current value of the problem counter is.
9207:
9208: Caches the results to $env{'form.scantron_maxbubble'},
9209: $env{'form.scantron.bubble_lines.n'},
9210: $env{'form.scantron.first_bubble_line.n'} and
9211: $env{"form.scantron.sub_bubblelines.n"}
9212: which are the total number of bubble, lines, the number of bubble
9213: lines for response n and number of the first bubble line for response n,
9214: and a comma separated list of numbers of bubble lines for sub-questions
9215: (for optionresponse, matchresponse, and rankresponse items), for response n.
9216:
9217:
9218: =item scantron_validate_missingbubbles() :
9219:
9220: Validates all scanlines in the selected file to not have any
9221: answers that don't have bubbles that have not been verified
9222: to be bubble free.
9223:
9224: =item scantron_process_students() :
9225:
9226: Routine that does the actual grading of the bubble sheet information.
9227:
9228: The parsed scanline hash is added to %env
9229:
9230: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9231: foreach resource , with the form data of
9232:
9233: 'submitted' =>'scantron'
9234: 'grade_target' =>'grade',
9235: 'grade_username'=> username of student
9236: 'grade_domain' => domain of student
9237: 'grade_courseid'=> of course
9238: 'grade_symb' => symb of resource to grade
9239:
9240: This triggers a grading pass. The problem grading code takes care
9241: of converting the bubbled letter information (now in %env) into a
9242: valid submission.
9243:
9244: =item scantron_upload_scantron_data() :
9245:
9246: Creates the screen for adding a new bubble sheet data file to a course.
9247:
9248: =item scantron_upload_scantron_data_save() :
9249:
9250: Adds a provided bubble information data file to the course if user
9251: has the correct privileges to do so.
9252:
9253: =item valid_file() :
9254:
9255: Validates that the requested bubble data file exists in the course.
9256:
9257: =item scantron_download_scantron_data() :
9258:
9259: Shows a list of the three internal files (original, corrected,
9260: skipped) for a specific bubble sheet data file that exists in the
9261: course.
9262:
9263: =item scantron_validate_ID() :
9264:
9265: Validates all scanlines in the selected file to not have any
9266: invalid or underspecified student/employee IDs
