5037: =head1 Bubble sheet grading routines
5038:
5039: For this documentation:
5040:
5041: 'scanline' refers to the full line of characters
5042: from the file that we are parsing that represents one entire sheet
5043:
5044: 'bubble line' refers to the data
5045: representing the line of bubbles that are on the physical bubblesheet
5046:
5047:
5048: The overall process is that a scanned in bubblesheet data is uploaded
5049: into a course. When a user wants to grade, they select a
5050: sequence/folder of resources, a file of bubblesheet info, and pick
5051: one of the predefined configurations for what each scanline looks
5052: like.
5053:
5054: Next each scanline is checked for any errors of either 'missing
5055: bubbles' (it's an error because it may have been mis-scanned
5056: because too light bubbling), 'double bubble' (each bubble line should
5057: have no more that one letter picked), invalid or duplicated CODE,
5058: invalid student/employee ID
5059:
5060: If the CODE option is used that determines the randomization of the
5061: homework problems, either way the student/employee ID is looked up into a
5062: username:domain.
5063:
5064: During the validation phase the instructor can choose to skip scanlines.
5065:
5066: After the validation phase, there are now 3 bubblesheet files
5067:
5068: scantron_original_filename (unmodified original file)
5069: scantron_corrected_filename (file where the corrected information has replaced the original information)
5070: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5071:
5072: Also there is a separate hash nohist_scantrondata that contains extra
5073: correction information that isn't representable in the bubblesheet
5074: file (see &scantron_getfile() for more information)
5075:
5076: After all scanlines are either valid, marked as valid or skipped, then
5077: foreach line foreach problem in the picked sequence, an ssi request is
5078: made that simulates a user submitting their selected letter(s) against
5079: the homework problem.

9946: =head1 NAME
9947:
9948: Apache::grades
9949:
9950: =head1 SYNOPSIS
9951:
9952: Handles the viewing of grades.
9953:
9954: This is part of the LearningOnline Network with CAPA project
9955: described at http://www.lon-capa.org.
9956:
9957: =head1 OVERVIEW
9958:
9959: Do an ssi with retries:
9960: While I'd love to factor out this with the vesrion in lonprintout,
9961: 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
9962: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9963:
9964: At least the logic that drives this has been pulled out into loncommon.
9965:
9966:
9967:
9968: ssi_with_retries - Does the server side include of a resource.
9969: if the ssi call returns an error we'll retry it up to
9970: the number of times requested by the caller.
9971: If we still have a proble, no text is appended to the
9972: output and we set some global variables.
9973: to indicate to the caller an SSI error occurred.
9974: All of this is supposed to deal with the issues described
9975: in LonCAPA BZ 5631 see:
9976: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9977: by informing the user that this happened.
9978:
9979: Parameters:
9980: resource - The resource to include. This is passed directly, without
9981: interpretation to lonnet::ssi.
9982: form - The form hash parameters that guide the interpretation of the resource
9983:
9984: retries - Number of retries allowed before giving up completely.
9985: Returns:
9986: On success, returns the rendered resource identified by the resource parameter.
9987: Side Effects:
9988: The following global variables can be set:
9989: ssi_error - If an unrecoverable error occurred this becomes true.
9990: It is up to the caller to initialize this to false
9991: if desired.
9992: ssi_error_resource - If an unrecoverable error occurred, this is the value
9993: of the resource that could not be rendered by the ssi
9994: call.

10010: can receive another opportunity. Access to tasks is slot-based. If a slot

10015: the submission screen provides a user with vgr privileges (e.g., a Course
10016: Coordinator) the ability to display a previous version worked on by the
10017: student. By default, the current version is displayed. If a previous version
10018: has been selected for display, submission data are only shown that pertain
