61: # Do an ssi with retries:
62: # While I'd love to factor out this with the vesrion in lonprintout,
63: # that would either require a data coupling between modules, which I refuse to perpetuate
64: # (there's quite enough of that already), or would require the invention of another infrastructure
65: # I'm not quite ready to invent (e.g. an ssi_with_retry object).
66: #
67: # At least the logic that drives this has been pulled out into loncommon.
68:
69:
70: #
71: # ssi_with_retries - Does the server side include of a resource.
72: # if the ssi call returns an error we'll retry it up to
73: # the number of times requested by the caller.
74: # If we still have a proble, no text is appended to the
75: # output and we set some global variables.
76: # to indicate to the caller an SSI error occurred.
77: # All of this is supposed to deal with the issues described
78: # in LonCAPA BZ 5631 see:
79: # http://bugs.lon-capa.org/show_bug.cgi?id=5631
80: # by informing the user that this happened.
81: #
82: # Parameters:
83: # resource - The resource to include. This is passed directly, without
84: # interpretation to lonnet::ssi.
85: # form - The form hash parameters that guide the interpretation of the resource
86: #
87: # retries - Number of retries allowed before giving up completely.
88: # Returns:
89: # On success, returns the rendered resource identified by the resource parameter.
90: # Side Effects:
91: # The following global variables can be set:
92: # ssi_error - If an unrecoverable error occurred this becomes true.
93: # It is up to the caller to initialize this to false
94: # if desired.
95: # ssi_error_resource - If an unrecoverable error occurred, this is the value
96: # of the resource that could not be rendered by the ssi
97: # call.
98: # ssi_error_message - The error string fetched from the ssi response
99: # in the event of an error.

4670: =head1 Bubble sheet grading routines
4671:
4672: For this documentation:
4673:
4674: 'scanline' refers to the full line of characters
4675: from the file that we are parsing that represents one entire sheet
4676:
4677: 'bubble line' refers to the data
4678: representing the line of bubbles that are on the physical bubble sheet
4679:
4680:
4681: The overall process is that a scanned in bubble sheet data is uploaded
4682: into a course. When a user wants to grade, they select a
4683: sequence/folder of resources, a file of bubble sheet info, and pick
4684: one of the predefined configurations for what each scanline looks
4685: like.
4686:
4687: Next each scanline is checked for any errors of either 'missing
4688: bubbles' (it's an error because it may have been mis-scanned
4689: because too light bubbling), 'double bubble' (each bubble line should
4690: have no more that one letter picked), invalid or duplicated CODE,
4691: invalid student ID
4692:
4693: If the CODE option is used that determines the randomization of the
4694: homework problems, either way the student ID is looked up into a
4695: username:domain.
4696:
4697: During the validation phase the instructor can choose to skip scanlines.
4698:
4699: After the validation phase, there are now 3 bubble sheet files
4700:
4701: scantron_original_filename (unmodified original file)
4702: scantron_corrected_filename (file where the corrected information has replaced the original information)
4703: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4704:
4705: Also there is a separate hash nohist_scantrondata that contains extra
4706: correction information that isn't representable in the bubble sheet
4707: file (see &scantron_getfile() for more information)
4708:
4709: After all scanlines are either valid, marked as valid or skipped, then
4710: foreach line foreach problem in the picked sequence, an ssi request is
4711: made that simulates a user submitting their selected letter(s) against
4712: the homework problem.

5390: Returns:
5391: Hash containing the result of parsing the scanline
5392:
5393: Keys are all proceeded by the string 'scantron.'
5394:
5395: CODE - the CODE in use for this scanline
5396: useCODE - 1 if the CODE is invalid but it usage has been forced
5397: by the operator
5398: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
5399: CODEs were selected, but the usage has been
5400: forced by the operator
5401: ID - student ID
5402: PaperID - if used, the ID number printed on the sheet when the
5403: paper was scanned
5404: FirstName - first name from the sheet
5405: LastName - last name from the sheet

5413: to a single question that have more than one bubble filled in.
5414: Of the form questionnumber::firstbubblenumber:count
5415:
5416: In the above, count is the number of bubble responses in the
5417: input line needed to represent the possible answers to the question.
5418: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
5419: per line would have count = 2.
5420:
5421: maxquest - the number of the last bubble line that was parsed
5422:
5423: (<number> starts at 1)
5424: <number>.answer - zero or more letters representing the selected
5425: letters from the scanline for the bubble line
5426: <number>.
5427: if blank there was either no bubble or there where
5428: multiple bubbles, (consult the keys missingerror and
5429: doubleerror if this is an error condition)
