1.424 albertel 5259: For this documentation:
5260:
5261: 'scanline' refers to the full line of characters
5262: from the file that we are parsing that represents one entire sheet
5263:
5264: 'bubble line' refers to the data
1.596.2.6 raeburn 5265: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5266:
5267:
1.596.2.6 raeburn 5268: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5269: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5270: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5271: one of the predefined configurations for what each scanline looks
5272: like.
5273:
5274: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5275: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5276: because too light bubbling), 'double bubble' (each bubble line should
1.596.2.12.2. 0(raebur 5277:3): have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5278: invalid student/employee ID
1.424 albertel 5279:
5280: If the CODE option is used that determines the randomization of the
1.556 weissno 5281: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5282: username:domain.
5283:
5284: During the validation phase the instructor can choose to skip scanlines.
5285:
1.596.2.6 raeburn 5286: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5287:
5288: scantron_original_filename (unmodified original file)
5289: scantron_corrected_filename (file where the corrected information has replaced the original information)
5290: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5291:
5292: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5293: correction information that isn't representable in the bubblesheet
1.424 albertel 5294: file (see &scantron_getfile() for more information)
5295:
5296: After all scanlines are either valid, marked as valid or skipped, then
5297: foreach line foreach problem in the picked sequence, an ssi request is
5298: made that simulates a user submitting their selected letter(s) against
5299: the homework problem.

10570: Apache::grades
10571:
10572: =head1 SYNOPSIS
10573:
10574: Handles the viewing of grades.
10575:
10576: This is part of the LearningOnline Network with CAPA project
10577: described at http://www.lon-capa.org.
10578:
10579: =head1 OVERVIEW
10580:
10581: Do an ssi with retries:
10582: While I'd love to factor out this with the vesrion in lonprintout,
10583: 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
10584: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10585:
10586: At least the logic that drives this has been pulled out into loncommon.
10587:
10588:
10589:
10590: ssi_with_retries - Does the server side include of a resource.
10591: if the ssi call returns an error we'll retry it up to
10592: the number of times requested by the caller.
1.596.2.12.2. 8(raebur 10593:4): If we still have a problem, no text is appended to the
1.531 jms 10594: output and we set some global variables.
10595: to indicate to the caller an SSI error occurred.
10596: All of this is supposed to deal with the issues described
1.596.2.12.2. 8(raebur 10597:4): in LON-CAPA BZ 5631 see:
1.531 jms 10598: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10599: by informing the user that this happened.
10600:
10601: Parameters:
10602: resource - The resource to include. This is passed directly, without
10603: interpretation to lonnet::ssi.
10604: form - The form hash parameters that guide the interpretation of the resource
10605:
10606: retries - Number of retries allowed before giving up completely.
10607: Returns:
10608: On success, returns the rendered resource identified by the resource parameter.
10609: Side Effects:
10610: The following global variables can be set:
10611: ssi_error - If an unrecoverable error occurred this becomes true.
10612: It is up to the caller to initialize this to false
10613: if desired.
10614: ssi_error_resource - If an unrecoverable error occurred, this is the value
10615: of the resource that could not be rendered by the ssi
10616: call.
10617: ssi_error_message - The error string fetched from the ssi response
10618: in the event of an error.
