5122: =head1 Bubble sheet grading routines
5123:
5124: For this documentation:
5125:
5126: 'scanline' refers to the full line of characters
5127: from the file that we are parsing that represents one entire sheet
5128:
5129: 'bubble line' refers to the data
5130: representing the line of bubbles that are on the physical bubblesheet
5131:
5132:
5133: The overall process is that a scanned in bubblesheet data is uploaded
5134: into a course. When a user wants to grade, they select a
5135: sequence/folder of resources, a file of bubblesheet info, and pick
5136: one of the predefined configurations for what each scanline looks
5137: like.
5138:
5139: Next each scanline is checked for any errors of either 'missing
5140: bubbles' (it's an error because it may have been mis-scanned
5141: because too light bubbling), 'double bubble' (each bubble line should
5142: have no more than one letter picked), invalid or duplicated CODE,
5143: invalid student/employee ID
5144:
5145: If the CODE option is used that determines the randomization of the
5146: homework problems, either way the student/employee ID is looked up into a
5147: username:domain.
5148:
5149: During the validation phase the instructor can choose to skip scanlines.
5150:
5151: After the validation phase, there are now 3 bubblesheet files
5152:
5153: scantron_original_filename (unmodified original file)
5154: scantron_corrected_filename (file where the corrected information has replaced the original information)
5155: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5156:
5157: Also there is a separate hash nohist_scantrondata that contains extra
5158: correction information that isn't representable in the bubblesheet
5159: file (see &scantron_getfile() for more information)
5160:
5161: After all scanlines are either valid, marked as valid or skipped, then
5162: foreach line foreach problem in the picked sequence, an ssi request is
5163: made that simulates a user submitting their selected letter(s) against
5164: the homework problem.

5938:
5939: Arguments:
5940: line - The text of the bubblesheet file line to process
5941: whichline - Line number
5942: scantron_config - Hash describing the format of the bubblesheet lines.
5943: scan_data - Hash of extra information about the scanline
5944: (see scantron_getfile for more information)
5945: just_header - True if should not process question answers but only
5946: the stuff to the left of the answers.
5947: randomorder - True if randomorder in use
5948: randompick - True if randompick in use
5949: sequence - Exam folder URL
5950: master_seq - Ref to array containing symbs in exam folder
5951: symb_to_resource - Ref to hash of symbs for resources in exam folder
5952: (corresponding values are resource objects)
5953: partids_by_symb - Ref to hash of symb -> array ref of partIDs
5954: orderedforcode - Ref to hash of arrays. keys are CODEs and values
5955: are refs to an array of resource objects, ordered
5956: according to order used for CODE, when randomorder
5957: and or randompick are in use.
5958: respnumlookup - Ref to hash mapping question numbers in bubble lines
5959: for current line to question number used for same question
5960: in "Master Sequence" (as seen by Course Coordinator).
5961: startline - Ref to hash where key is question number (0 is first)
5962: and value is number of first bubble line for current
5963: student or code-based randompick and/or randomorder.
5964: totalref - Ref of scalar used to score total number of bubble
5965: lines needed for responses in a scan line (used when
5966: randompick in use.
5967:
5968: Returns:
5969: Hash containing the result of parsing the scanline
5970:
5971: Keys are all proceeded by the string 'scantron.'
5972:
5973: CODE - the CODE in use for this scanline
5974: useCODE - 1 if the CODE is invalid but it usage has been forced
5975: by the operator
5976: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
5977: CODEs were selected, but the usage has been
5978: forced by the operator
5979: ID - student/employee ID

5991: to a single question that have more than one bubble filled in.
5992: Of the form questionnumber::firstbubblenumber:count
5993:
5994: In the above, count is the number of bubble responses in the
5995: input line needed to represent the possible answers to the question.
5996: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
5997: per line would have count = 2.
5998:

10412:
10413: =head1 SYNOPSIS
10414:
10415: Handles the viewing of grades.
10416:
10417: This is part of the LearningOnline Network with CAPA project
10418: described at http://www.lon-capa.org.
10419:
10420: =head1 OVERVIEW
10421:
10422: Do an ssi with retries:
10423: While I'd love to factor out this with the version in lonprintout,
10424: 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
10425: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10426:
10427: At least the logic that drives this has been pulled out into loncommon.

10431: ssi_with_retries - Does the server side include of a resource.
10432: if the ssi call returns an error we'll retry it up to
10433: the number of times requested by the caller.
10434: If we still have a problem, no text is appended to the
10435: output and we set some global variables.
10436: to indicate to the caller an SSI error occurred.
10437: All of this is supposed to deal with the issues described
10438: in LON-CAPA BZ 5631 see:
10439: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10440: by informing the user that this happened.
10441:
10442: Parameters:
10443: resource - The resource to include. This is passed directly, without
10444: interpretation to lonnet::ssi.
10445: form - The form hash parameters that guide the interpretation of the resource
10446:
10447: retries - Number of retries allowed before giving up completely.
10448: Returns:
10449: On success, returns the rendered resource identified by the resource parameter.
10450: Side Effects:
10451: The following global variables can be set:
10452: ssi_error - If an unrecoverable error occurred this becomes true.
10453: It is up to the caller to initialize this to false
10454: if desired.
10455: ssi_error_resource - If an unrecoverable error occurred, this is the value
10456: of the resource that could not be rendered by the ssi
10457: call.
10458: ssi_error_message - The error string fetched from the ssi response
10459: in the event of an error.

10471:
10472: Tasks are graded pass/fail. Students who have yet to pass a particular Task

10478: the submission screen provides a user with vgr privileges (e.g., a Course

10480: student. By default, the current version is displayed. If a previous version
