Bug 6476
- Revert part of changes in grades.pm rev. 1.732
- When the random seed is stored, store rawrndseed (the pre-processed random
seed) in resource.$part.rndseed, since the pre-processed seed is the one
needed to reconstruct the problem in Authoring Space.
- Retains backwards-compatibility with data stored in 2.10 and 2.11, because
the previous tries display, and submission history in the grading screens
for questiontype of randmizetry both expect resource.$part.rndseed in the
submission history (and for randomizetry the rawrndseed and rndseed are
the same).

5106: =head1 Bubble sheet grading routines
5107:
5108: For this documentation:
5109:
5110: 'scanline' refers to the full line of characters
5111: from the file that we are parsing that represents one entire sheet
5112:
5113: 'bubble line' refers to the data
5114: representing the line of bubbles that are on the physical bubblesheet
5115:
5116:
5117: The overall process is that a scanned in bubblesheet data is uploaded
5118: into a course. When a user wants to grade, they select a
5119: sequence/folder of resources, a file of bubblesheet info, and pick
5120: one of the predefined configurations for what each scanline looks
5121: like.
5122:
5123: Next each scanline is checked for any errors of either 'missing
5124: bubbles' (it's an error because it may have been mis-scanned
5125: because too light bubbling), 'double bubble' (each bubble line should
5126: have no more than one letter picked), invalid or duplicated CODE,
5127: invalid student/employee ID
5128:
5129: If the CODE option is used that determines the randomization of the
5130: homework problems, either way the student/employee ID is looked up into a
5131: username:domain.
5132:
5133: During the validation phase the instructor can choose to skip scanlines.
5134:
5135: After the validation phase, there are now 3 bubblesheet files
5136:
5137: scantron_original_filename (unmodified original file)
5138: scantron_corrected_filename (file where the corrected information has replaced the original information)
5139: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5140:
5141: Also there is a separate hash nohist_scantrondata that contains extra
5142: correction information that isn't representable in the bubblesheet
5143: file (see &scantron_getfile() for more information)
5144:
5145: After all scanlines are either valid, marked as valid or skipped, then
5146: foreach line foreach problem in the picked sequence, an ssi request is
5147: made that simulates a user submitting their selected letter(s) against
5148: the homework problem.

5919: Decodes a scanline from the selected bubblesheet file
5920:
5921: Arguments:
5922: line - The text of the bubblesheet file line to process
5923: whichline - Line number
5924: scantron_config - Hash describing the format of the bubblesheet lines.
5925: scan_data - Hash of extra information about the scanline
5926: (see scantron_getfile for more information)
5927: just_header - True if should not process question answers but only
5928: the stuff to the left of the answers.
5929: randomorder - True if randomorder in use
5930: randompick - True if randompick in use
5931: sequence - Exam folder URL
5932: master_seq - Ref to array containing symbs in exam folder
5933: symb_to_resource - Ref to hash of symbs for resources in exam folder
5934: (corresponding values are resource objects)
5935: partids_by_symb - Ref to hash of symb -> array ref of partIDs
5936: orderedforcode - Ref to hash of arrays. keys are CODEs and values
5937: are refs to an array of resource objects, ordered
5938: according to order used for CODE, when randomorder
5939: and or randompick are in use.
5940: respnumlookup - Ref to hash mapping question numbers in bubble lines
5941: for current line to question number used for same question
5942: in "Master Sequence" (as seen by Course Coordinator).
5943: startline - Ref to hash where key is question number (0 is first)
5944: and value is number of first bubble line for current
5945: student or code-based randompick and/or randomorder.
5946: totalref - Ref of scalar used to score total number of bubble
5947: lines needed for responses in a scan line (used when
5948: randompick in use.
5949:
5950: Returns:
5951: Hash containing the result of parsing the scanline
5952:
5953: Keys are all proceeded by the string 'scantron.'
5954:
5955: CODE - the CODE in use for this scanline
5956: useCODE - 1 if the CODE is invalid but it usage has been forced
5957: by the operator
5958: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
5959: CODEs were selected, but the usage has been
5960: forced by the operator
5961: ID - student/employee ID
5962: PaperID - if used, the ID number printed on the sheet when the
5963: paper was scanned
5964: FirstName - first name from the sheet
5965: LastName - last name from the sheet
5966:
5967: if just_header was not true these key may also exist
5968:
5969: missingerror - a list of bubble ranges that are considered to be answers
5970: to a single question that don't have any bubbles filled in.
5971: Of the form questionnumber:firstbubblenumber:count.
5972: doubleerror - a list of bubble ranges that are considered to be answers
5973: to a single question that have more than one bubble filled in.
5974: Of the form questionnumber::firstbubblenumber:count
5975:
5976: In the above, count is the number of bubble responses in the
5977: input line needed to represent the possible answers to the question.
5978: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
5979: per line would have count = 2.
5980:
5981: maxquest - the number of the last bubble line that was parsed
5982:
5983: (<number> starts at 1)
5984: <number>.answer - zero or more letters representing the selected
5985: letters from the scanline for the bubble line
5986: <number>.
5987: if blank there was either no bubble or there where
5988: multiple bubbles, (consult the keys missingerror and

10390: Apache::grades
10391:
10392: =head1 SYNOPSIS
10393:
10394: Handles the viewing of grades.
10395:
10396: This is part of the LearningOnline Network with CAPA project
10397: described at http://www.lon-capa.org.
10398:
10399: =head1 OVERVIEW
10400:
10401: Do an ssi with retries:
10402: While I'd love to factor out this with the version in lonprintout,
10403: 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
10404: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10405:
10406: At least the logic that drives this has been pulled out into loncommon.
10407:
10408:
10409:
10410: ssi_with_retries - Does the server side include of a resource.
10411: if the ssi call returns an error we'll retry it up to
10412: the number of times requested by the caller.
10413: If we still have a problem, no text is appended to the
10414: output and we set some global variables.
10415: to indicate to the caller an SSI error occurred.
10416: All of this is supposed to deal with the issues described
10417: in LON-CAPA BZ 5631 see:
10418: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10419: by informing the user that this happened.
10420:
10421: Parameters:
10422: resource - The resource to include. This is passed directly, without
10423: interpretation to lonnet::ssi.
10424: form - The form hash parameters that guide the interpretation of the resource
10425:
10426: retries - Number of retries allowed before giving up completely.
10427: Returns:
10428: On success, returns the rendered resource identified by the resource parameter.
10429: Side Effects:
10430: The following global variables can be set:
10431: ssi_error - If an unrecoverable error occurred this becomes true.
10432: It is up to the caller to initialize this to false
10433: if desired.
10434: ssi_error_resource - If an unrecoverable error occurred, this is the value
10435: of the resource that could not be rendered by the ssi
10436: call.
10437: ssi_error_message - The error string fetched from the ssi response
10438: in the event of an error.

10459: student. By default, the current version is displayed. If a previous version
