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

9243: =head1 OVERVIEW
9244:
9245: Do an ssi with retries:
9246: While I'd love to factor out this with the vesrion in lonprintout,
9247: 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
9248: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9249:
9250: At least the logic that drives this has been pulled out into loncommon.
9251:
9252:
9253:
9254: ssi_with_retries - Does the server side include of a resource.
9255: if the ssi call returns an error we'll retry it up to
9256: the number of times requested by the caller.
9257: If we still have a proble, no text is appended to the
9258: output and we set some global variables.
9259: to indicate to the caller an SSI error occurred.
9260: All of this is supposed to deal with the issues described
9261: in LonCAPA BZ 5631 see:
9262: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9263: by informing the user that this happened.
9264:
9265: Parameters:
9266: resource - The resource to include. This is passed directly, without
9267: interpretation to lonnet::ssi.
9268: form - The form hash parameters that guide the interpretation of the resource
9269:
9270: retries - Number of retries allowed before giving up completely.
9271: Returns:
9272: On success, returns the rendered resource identified by the resource parameter.
9273: Side Effects:
9274: The following global variables can be set:
9275: ssi_error - If an unrecoverable error occurred this becomes true.
9276: It is up to the caller to initialize this to false
9277: if desired.
9278: ssi_error_resource - If an unrecoverable error occurred, this is the value
9279: of the resource that could not be rendered by the ssi
9280: call.
9281: ssi_error_message - The error string fetched from the ssi response
9282: in the event of an error.

9293: =item scantron_get_correction() :
9294:
9295: Builds the interface screen to interact with the operator to fix a
9296: specific error condition in a specific scanline
9297:
9298: Arguments:
9299: $r - Apache request object
9300: $i - number of the current scanline
9301: $scan_record - hash ref as returned from &scantron_parse_scanline()
9302: $scan_config - hash ref as returned from &get_scantron_config()
9303: $line - full contents of the current scanline
9304: $error - error condition, valid values are
9305: 'incorrectCODE', 'duplicateCODE',
9306: 'doublebubble', 'missingbubble',
9307: 'duplicateID', 'incorrectID'
9308: $arg - extra information needed
9309: For errors:
9310: - duplicateID - paper number that this studentID was seen before on
9311: - duplicateCODE - array ref of the paper numbers this CODE was
9312: seen on before
9313: - incorrectCODE - current incorrect CODE
9314: - doublebubble - array ref of the bubble lines that have double
9315: bubble errors
9316: - missingbubble - array ref of the bubble lines that have missing
9317: bubble errors
9318:
9319: =item scantron_get_maxbubble() :
9320:
9321: Returns the maximum number of bubble lines that are expected to
9322: occur. Does this by walking the selected sequence rendering the
9323: resource and then checking &Apache::lonxml::get_problem_counter()
9324: for what the current value of the problem counter is.
9325:
9326: Caches the results to $env{'form.scantron_maxbubble'},
9327: $env{'form.scantron.bubble_lines.n'},
9328: $env{'form.scantron.first_bubble_line.n'} and
9329: $env{"form.scantron.sub_bubblelines.n"}
9330: which are the total number of bubble, lines, the number of bubble
9331: lines for response n and number of the first bubble line for response n,
9332: and a comma separated list of numbers of bubble lines for sub-questions
9333: (for optionresponse, matchresponse, and rankresponse items), for response n.
9334:
9335:
9336: =item scantron_validate_missingbubbles() :
9337:
9338: Validates all scanlines in the selected file to not have any
9339: answers that don't have bubbles that have not been verified
9340: to be bubble free.
9341:
9342: =item scantron_process_students() :
9343:
9344: Routine that does the actual grading of the bubble sheet information.
9345:
9346: The parsed scanline hash is added to %env
9347:
9348: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9349: foreach resource , with the form data of
9350:
9351: 'submitted' =>'scantron'
9352: 'grade_target' =>'grade',
9353: 'grade_username'=> username of student
9354: 'grade_domain' => domain of student
9355: 'grade_courseid'=> of course
9356: 'grade_symb' => symb of resource to grade
9357:
9358: This triggers a grading pass. The problem grading code takes care
9359: of converting the bubbled letter information (now in %env) into a
9360: valid submission.
9361:
9362: =item scantron_upload_scantron_data() :
9363:
9364: Creates the screen for adding a new bubble sheet data file to a course.
9365:
9366: =item scantron_upload_scantron_data_save() :
9367:
9368: Adds a provided bubble information data file to the course if user
9369: has the correct privileges to do so.
9370:
9371: =item valid_file() :
9372:
9373: Validates that the requested bubble data file exists in the course.
9374:
9375: =item scantron_download_scantron_data() :
9376:
9377: Shows a list of the three internal files (original, corrected,
9378: skipped) for a specific bubble sheet data file that exists in the
9379: course.
9380:
9381: =item scantron_validate_ID() :
9382:
9383: Validates all scanlines in the selected file to not have any
