1.424 albertel 5265: For this documentation:
5266:
5267: 'scanline' refers to the full line of characters
5268: from the file that we are parsing that represents one entire sheet
5269:
5270: 'bubble line' refers to the data
1.596.2.6 raeburn 5271: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5272:
5273:
1.596.2.6 raeburn 5274: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5275: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5276: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5277: one of the predefined configurations for what each scanline looks
5278: like.
5279:
5280: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5281: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5282: because too light bubbling), 'double bubble' (each bubble line should
1.596.2.12.2. 0(raebur 5283:3): have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5284: invalid student/employee ID
1.424 albertel 5285:
5286: If the CODE option is used that determines the randomization of the
1.556 weissno 5287: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5288: username:domain.
5289:
5290: During the validation phase the instructor can choose to skip scanlines.
5291:
1.596.2.6 raeburn 5292: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5293:
5294: scantron_original_filename (unmodified original file)
5295: scantron_corrected_filename (file where the corrected information has replaced the original information)
5296: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5297:
5298: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5299: correction information that isn't representable in the bubblesheet
1.424 albertel 5300: file (see &scantron_getfile() for more information)
5301:
5302: After all scanlines are either valid, marked as valid or skipped, then
5303: foreach line foreach problem in the picked sequence, an ssi request is
5304: made that simulates a user submitting their selected letter(s) against
5305: the homework problem.

10577:
10578: =head1 SYNOPSIS
10579:
10580: Handles the viewing of grades.
10581:
10582: This is part of the LearningOnline Network with CAPA project
10583: described at http://www.lon-capa.org.
10584:
10585: =head1 OVERVIEW
10586:
10587: Do an ssi with retries:
10588: While I'd love to factor out this with the vesrion in lonprintout,
10589: 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
10590: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10591:
10592: At least the logic that drives this has been pulled out into loncommon.
10593:
10594:
10595:
10596: ssi_with_retries - Does the server side include of a resource.
10597: if the ssi call returns an error we'll retry it up to
10598: the number of times requested by the caller.
1.596.2.12.2. 8(raebur 10599:4): If we still have a problem, no text is appended to the
1.531 jms 10600: output and we set some global variables.
10601: to indicate to the caller an SSI error occurred.
10602: All of this is supposed to deal with the issues described
1.596.2.12.2. 8(raebur 10603:4): in LON-CAPA BZ 5631 see:
1.531 jms 10604: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10605: by informing the user that this happened.
10606:
10607: Parameters:
10608: resource - The resource to include. This is passed directly, without
10609: interpretation to lonnet::ssi.
10610: form - The form hash parameters that guide the interpretation of the resource
10611:
10612: retries - Number of retries allowed before giving up completely.
10613: Returns:
10614: On success, returns the rendered resource identified by the resource parameter.
10615: Side Effects:
10616: The following global variables can be set:
10617: ssi_error - If an unrecoverable error occurred this becomes true.
10618: It is up to the caller to initialize this to false
10619: if desired.
10620: ssi_error_resource - If an unrecoverable error occurred, this is the value
10621: of the resource that could not be rendered by the ssi
10622: call.
10623: ssi_error_message - The error string fetched from the ssi response
10624: in the event of an error.
