4707: =head1 Bubble sheet grading routines
4708:
1.424 albertel 4709: For this documentation:
4710:
4711: 'scanline' refers to the full line of characters
4712: from the file that we are parsing that represents one entire sheet
4713:
4714: 'bubble line' refers to the data
4715: representing the line of bubbles that are on the physical bubble sheet
4716:
4717:
4718: The overall process is that a scanned in bubble sheet data is uploaded
4719: into a course. When a user wants to grade, they select a
4720: sequence/folder of resources, a file of bubble sheet info, and pick
4721: one of the predefined configurations for what each scanline looks
4722: like.
4723:
4724: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4725: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4726: because too light bubbling), 'double bubble' (each bubble line should
4727: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4728: invalid student/employee ID
1.424 albertel 4729:
4730: If the CODE option is used that determines the randomization of the
1.556 weissno 4731: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4732: username:domain.
4733:
4734: During the validation phase the instructor can choose to skip scanlines.
4735:
1.435 foxr 4736: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4737:
4738: scantron_original_filename (unmodified original file)
4739: scantron_corrected_filename (file where the corrected information has replaced the original information)
4740: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4741:
4742: Also there is a separate hash nohist_scantrondata that contains extra
4743: correction information that isn't representable in the bubble sheet
4744: file (see &scantron_getfile() for more information)
4745:
4746: After all scanlines are either valid, marked as valid or skipped, then
4747: foreach line foreach problem in the picked sequence, an ssi request is
4748: made that simulates a user submitting their selected letter(s) against
4749: the homework problem.

9244: =head1 OVERVIEW
9245:
9246: Do an ssi with retries:
9247: While I'd love to factor out this with the vesrion in lonprintout,
9248: 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
9249: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9250:
9251: At least the logic that drives this has been pulled out into loncommon.
9252:
9253:
9254:
9255: ssi_with_retries - Does the server side include of a resource.
9256: if the ssi call returns an error we'll retry it up to
9257: the number of times requested by the caller.
9258: If we still have a proble, no text is appended to the
9259: output and we set some global variables.
9260: to indicate to the caller an SSI error occurred.
9261: All of this is supposed to deal with the issues described
9262: in LonCAPA BZ 5631 see:
9263: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9264: by informing the user that this happened.
9265:
9266: Parameters:
9267: resource - The resource to include. This is passed directly, without
9268: interpretation to lonnet::ssi.
9269: form - The form hash parameters that guide the interpretation of the resource
9270:
9271: retries - Number of retries allowed before giving up completely.
9272: Returns:
9273: On success, returns the rendered resource identified by the resource parameter.
9274: Side Effects:
9275: The following global variables can be set:
9276: ssi_error - If an unrecoverable error occurred this becomes true.
9277: It is up to the caller to initialize this to false
9278: if desired.
9279: ssi_error_resource - If an unrecoverable error occurred, this is the value
9280: of the resource that could not be rendered by the ssi
9281: call.
9282: ssi_error_message - The error string fetched from the ssi response
9283: in the event of an error.

9294: =item scantron_get_correction() :
9295:
9296: Builds the interface screen to interact with the operator to fix a
9297: specific error condition in a specific scanline
9298:
9299: Arguments:
9300: $r - Apache request object
9301: $i - number of the current scanline
9302: $scan_record - hash ref as returned from &scantron_parse_scanline()
9303: $scan_config - hash ref as returned from &get_scantron_config()
9304: $line - full contents of the current scanline
9305: $error - error condition, valid values are
9306: 'incorrectCODE', 'duplicateCODE',
9307: 'doublebubble', 'missingbubble',
9308: 'duplicateID', 'incorrectID'
9309: $arg - extra information needed
9310: For errors:
9311: - duplicateID - paper number that this studentID was seen before on
9312: - duplicateCODE - array ref of the paper numbers this CODE was
9313: seen on before
9314: - incorrectCODE - current incorrect CODE
9315: - doublebubble - array ref of the bubble lines that have double
9316: bubble errors
9317: - missingbubble - array ref of the bubble lines that have missing
9318: bubble errors
9319:
9320: =item scantron_get_maxbubble() :
9321:
9322: Returns the maximum number of bubble lines that are expected to
9323: occur. Does this by walking the selected sequence rendering the
9324: resource and then checking &Apache::lonxml::get_problem_counter()
9325: for what the current value of the problem counter is.
9326:
9327: Caches the results to $env{'form.scantron_maxbubble'},
9328: $env{'form.scantron.bubble_lines.n'},
9329: $env{'form.scantron.first_bubble_line.n'} and
9330: $env{"form.scantron.sub_bubblelines.n"}
9331: which are the total number of bubble, lines, the number of bubble
9332: lines for response n and number of the first bubble line for response n,
9333: and a comma separated list of numbers of bubble lines for sub-questions
9334: (for optionresponse, matchresponse, and rankresponse items), for response n.
9335:
9336:
9337: =item scantron_validate_missingbubbles() :
9338:
9339: Validates all scanlines in the selected file to not have any
9340: answers that don't have bubbles that have not been verified
9341: to be bubble free.
9342:
9343: =item scantron_process_students() :
9344:
9345: Routine that does the actual grading of the bubble sheet information.
9346:
9347: The parsed scanline hash is added to %env
9348:
9349: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9350: foreach resource , with the form data of
9351:
9352: 'submitted' =>'scantron'
9353: 'grade_target' =>'grade',
9354: 'grade_username'=> username of student
9355: 'grade_domain' => domain of student
9356: 'grade_courseid'=> of course
9357: 'grade_symb' => symb of resource to grade
9358:
9359: This triggers a grading pass. The problem grading code takes care
9360: of converting the bubbled letter information (now in %env) into a
9361: valid submission.
9362:
9363: =item scantron_upload_scantron_data() :
9364:
9365: Creates the screen for adding a new bubble sheet data file to a course.
9366:
9367: =item scantron_upload_scantron_data_save() :
9368:
9369: Adds a provided bubble information data file to the course if user
9370: has the correct privileges to do so.
9371:
9372: =item valid_file() :
9373:
9374: Validates that the requested bubble data file exists in the course.
9375:
9376: =item scantron_download_scantron_data() :
9377:
9378: Shows a list of the three internal files (original, corrected,
9379: skipped) for a specific bubble sheet data file that exists in the
9380: course.
9381:
9382: =item scantron_validate_ID() :
9383:
9384: Validates all scanlines in the selected file to not have any
