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.
1.516 raeburn 76: # to indicate to the caller an SSI error occurred.
1.513 foxr 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:
1.516 raeburn 92: # ssi_error - If an unrecoverable error occurred this becomes true.
1.513 foxr 93: # It is up to the caller to initialize this to false
94: # if desired.
1.516 raeburn 95: # ssi_error_resource - If an unrecoverable error occurred, this is the value
1.513 foxr 96: # of the resource that could not be rendered by the ssi
97: # call.

4675: =head1 Bubble sheet grading routines
4676:
1.424 albertel 4677: For this documentation:
4678:
4679: 'scanline' refers to the full line of characters
4680: from the file that we are parsing that represents one entire sheet
4681:
4682: 'bubble line' refers to the data
4683: representing the line of bubbles that are on the physical bubble sheet
4684:
4685:
4686: The overall process is that a scanned in bubble sheet data is uploaded
4687: into a course. When a user wants to grade, they select a
4688: sequence/folder of resources, a file of bubble sheet info, and pick
4689: one of the predefined configurations for what each scanline looks
4690: like.
4691:
4692: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4693: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4694: because too light bubbling), 'double bubble' (each bubble line should
4695: have no more that one letter picked), invalid or duplicated CODE,
4696: invalid student ID
4697:
4698: If the CODE option is used that determines the randomization of the
4699: homework problems, either way the student ID is looked up into a
4700: username:domain.
4701:
4702: During the validation phase the instructor can choose to skip scanlines.
4703:
1.435 foxr 4704: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4705:
4706: scantron_original_filename (unmodified original file)
4707: scantron_corrected_filename (file where the corrected information has replaced the original information)
4708: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4709:
4710: Also there is a separate hash nohist_scantrondata that contains extra
4711: correction information that isn't representable in the bubble sheet
4712: file (see &scantron_getfile() for more information)
4713:
4714: After all scanlines are either valid, marked as valid or skipped, then
4715: foreach line foreach problem in the picked sequence, an ssi request is
4716: made that simulates a user submitting their selected letter(s) against
4717: the homework problem.
