4700:
1.424 albertel 4701: For this documentation:
4702:
4703: 'scanline' refers to the full line of characters
4704: from the file that we are parsing that represents one entire sheet
4705:
4706: 'bubble line' refers to the data
4707: representing the line of bubbles that are on the physical bubble sheet
4708:
4709:
4710: The overall process is that a scanned in bubble sheet data is uploaded
4711: into a course. When a user wants to grade, they select a
4712: sequence/folder of resources, a file of bubble sheet info, and pick
4713: one of the predefined configurations for what each scanline looks
4714: like.
4715:
4716: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4717: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4718: because too light bubbling), 'double bubble' (each bubble line should
4719: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4720: invalid student/employee ID
1.424 albertel 4721:
4722: If the CODE option is used that determines the randomization of the
1.556 weissno 4723: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4724: username:domain.
4725:
4726: During the validation phase the instructor can choose to skip scanlines.
4727:
1.435 foxr 4728: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4729:
4730: scantron_original_filename (unmodified original file)
4731: scantron_corrected_filename (file where the corrected information has replaced the original information)
4732: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4733:
4734: Also there is a separate hash nohist_scantrondata that contains extra
4735: correction information that isn't representable in the bubble sheet
4736: file (see &scantron_getfile() for more information)
4737:
4738: After all scanlines are either valid, marked as valid or skipped, then
4739: foreach line foreach problem in the picked sequence, an ssi request is
4740: made that simulates a user submitting their selected letter(s) against
4741: the homework problem.

9248: Do an ssi with retries:
9249: While I'd love to factor out this with the vesrion in lonprintout,
9250: 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
9251: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9252:
9253: At least the logic that drives this has been pulled out into loncommon.
9254:
9255:
9256:
9257: ssi_with_retries - Does the server side include of a resource.
9258: if the ssi call returns an error we'll retry it up to
9259: the number of times requested by the caller.
9260: If we still have a proble, no text is appended to the
9261: output and we set some global variables.
9262: to indicate to the caller an SSI error occurred.
9263: All of this is supposed to deal with the issues described
9264: in LonCAPA BZ 5631 see:
9265: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9266: by informing the user that this happened.
9267:
9268: Parameters:
9269: resource - The resource to include. This is passed directly, without
9270: interpretation to lonnet::ssi.
9271: form - The form hash parameters that guide the interpretation of the resource
9272:
9273: retries - Number of retries allowed before giving up completely.
9274: Returns:
9275: On success, returns the rendered resource identified by the resource parameter.
9276: Side Effects:
9277: The following global variables can be set:
9278: ssi_error - If an unrecoverable error occurred this becomes true.
9279: It is up to the caller to initialize this to false
9280: if desired.
9281: ssi_error_resource - If an unrecoverable error occurred, this is the value
9282: of the resource that could not be rendered by the ssi
9283: call.
9284: ssi_error_message - The error string fetched from the ssi response
9285: in the event of an error.

9300:
9301: Arguments:
9302: $r - Apache request object
9303: $i - number of the current scanline
9304: $scan_record - hash ref as returned from &scantron_parse_scanline()
9305: $scan_config - hash ref as returned from &get_scantron_config()
9306: $line - full contents of the current scanline
9307: $error - error condition, valid values are
9308: 'incorrectCODE', 'duplicateCODE',
9309: 'doublebubble', 'missingbubble',
9310: 'duplicateID', 'incorrectID'
9311: $arg - extra information needed
9312: For errors:
9313: - duplicateID - paper number that this studentID was seen before on
9314: - duplicateCODE - array ref of the paper numbers this CODE was
9315: seen on before
9316: - incorrectCODE - current incorrect CODE
9317: - doublebubble - array ref of the bubble lines that have double

9322: =item scantron_get_maxbubble() :

9324: Returns the maximum number of bubble lines that are expected to

9327: for what the current value of the problem counter is.
9328:
9329: Caches the results to $env{'form.scantron_maxbubble'},

9331: $env{'form.scantron.first_bubble_line.n'} and
9332: $env{"form.scantron.sub_bubblelines.n"}
9333: which are the total number of bubble, lines, the number of bubble
9334: lines for response n and number of the first bubble line for response n,
9335: and a comma separated list of numbers of bubble lines for sub-questions
9336: (for optionresponse, matchresponse, and rankresponse items), for response n.

9361: This triggers a grading pass. The problem grading code takes care
