1.424 albertel 5757: For this documentation:
5758:
5759: 'scanline' refers to the full line of characters
5760: from the file that we are parsing that represents one entire sheet
5761:
5762: 'bubble line' refers to the data
1.659 raeburn 5763: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5764:
5765:
1.659 raeburn 5766: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5767: into a course. When a user wants to grade, they select a
1.659 raeburn 5768: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5769: one of the predefined configurations for what each scanline looks
5770: like.
5771:
5772: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5773: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5774: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5775: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5776: invalid student/employee ID
1.424 albertel 5777:
5778: If the CODE option is used that determines the randomization of the
1.556 weissno 5779: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5780: username:domain.
5781:
5782: During the validation phase the instructor can choose to skip scanlines.
5783:
1.659 raeburn 5784: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5785:
5786: scantron_original_filename (unmodified original file)
5787: scantron_corrected_filename (file where the corrected information has replaced the original information)
5788: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5789:
5790: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5791: correction information that isn't representable in the bubblesheet
1.424 albertel 5792: file (see &scantron_getfile() for more information)
5793:
5794: After all scanlines are either valid, marked as valid or skipped, then
5795: foreach line foreach problem in the picked sequence, an ssi request is
5796: made that simulates a user submitting their selected letter(s) against
5797: the homework problem.

1.715 bisitz 11585: While I'd love to factor out this with the version in lonprintout,
1.531 jms 11586: 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
11587: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11588:
11589: At least the logic that drives this has been pulled out into loncommon.
11590:
11591:
11592:
11593: ssi_with_retries - Does the server side include of a resource.
11594: if the ssi call returns an error we'll retry it up to
11595: the number of times requested by the caller.
1.715 bisitz 11596: If we still have a problem, no text is appended to the
1.531 jms 11597: output and we set some global variables.
11598: to indicate to the caller an SSI error occurred.
11599: All of this is supposed to deal with the issues described
1.715 bisitz 11600: in LON-CAPA BZ 5631 see:
1.531 jms 11601: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11602: by informing the user that this happened.
11603:
11604: Parameters:
11605: resource - The resource to include. This is passed directly, without
11606: interpretation to lonnet::ssi.
11607: form - The form hash parameters that guide the interpretation of the resource
11608:
11609: retries - Number of retries allowed before giving up completely.
11610: Returns:
11611: On success, returns the rendered resource identified by the resource parameter.
11612: Side Effects:
11613: The following global variables can be set:
11614: ssi_error - If an unrecoverable error occurred this becomes true.
11615: It is up to the caller to initialize this to false
11616: if desired.
11617: ssi_error_resource - If an unrecoverable error occurred, this is the value
11618: of the resource that could not be rendered by the ssi
11619: call.
11620: ssi_error_message - The error string fetched from the ssi response
11621: in the event of an error.
