HEAD
- Starting with lonnet.pm rev 1.981, default for &lonnet::delenv() has been to \Q escape arg in regexp used to identify items in environment to delete.
- No longer need to escape special characters in arg passed to lonnet::delenv().
- Call to lonnet::delenv() in rat/lonuserstate now includes second arg, because in this case first arg is to be treated as a regexp (so \Q escape is not wanted).

4637: =head1 Bubble sheet grading routines
4638:
4639: For this documentation:
4640:
4641: 'scanline' refers to the full line of characters
4642: from the file that we are parsing that represents one entire sheet
4643:
4644: 'bubble line' refers to the data
4645: representing the line of bubbles that are on the physical bubble sheet
4646:
4647:
4648: The overall process is that a scanned in bubble sheet data is uploaded
4649: into a course. When a user wants to grade, they select a
4650: sequence/folder of resources, a file of bubble sheet info, and pick
4651: one of the predefined configurations for what each scanline looks
4652: like.
4653:
4654: Next each scanline is checked for any errors of either 'missing
4655: bubbles' (it's an error because it may have been mis-scanned
4656: because too light bubbling), 'double bubble' (each bubble line should
4657: have no more that one letter picked), invalid or duplicated CODE,
4658: invalid student ID
4659:
4660: If the CODE option is used that determines the randomization of the
4661: homework problems, either way the student ID is looked up into a
4662: username:domain.
4663:
4664: During the validation phase the instructor can choose to skip scanlines.
4665:
4666: After the validation phase, there are now 3 bubble sheet files
4667:
4668: scantron_original_filename (unmodified original file)
4669: scantron_corrected_filename (file where the corrected information has replaced the original information)
4670: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4671:
4672: Also there is a separate hash nohist_scantrondata that contains extra
4673: correction information that isn't representable in the bubble sheet
4674: file (see &scantron_getfile() for more information)
4675:
4676: After all scanlines are either valid, marked as valid or skipped, then
4677: foreach line foreach problem in the picked sequence, an ssi request is
4678: made that simulates a user submitting their selected letter(s) against
4679: the homework problem.

9011:
9012: Apache::grades
9013:
9014: =head1 SYNOPSIS
9015:
9016: Handles the viewing of grades.
9017:
9018: This is part of the LearningOnline Network with CAPA project
9019: described at http://www.lon-capa.org.
9020:
9021: =head1 OVERVIEW
9022:
9023: Do an ssi with retries:
9024: While I'd love to factor out this with the vesrion in lonprintout,
9025: 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
9026: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9027:
9028: At least the logic that drives this has been pulled out into loncommon.
9029:
9030:
9031:
9032: ssi_with_retries - Does the server side include of a resource.
9033: if the ssi call returns an error we'll retry it up to
9034: the number of times requested by the caller.
9035: If we still have a proble, no text is appended to the
9036: output and we set some global variables.
9037: to indicate to the caller an SSI error occurred.
9038: All of this is supposed to deal with the issues described
9039: in LonCAPA BZ 5631 see:
9040: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9041: by informing the user that this happened.
9042:
9043: Parameters:
9044: resource - The resource to include. This is passed directly, without
9045: interpretation to lonnet::ssi.
9046: form - The form hash parameters that guide the interpretation of the resource
9047:
9048: retries - Number of retries allowed before giving up completely.
9049: Returns:
9050: On success, returns the rendered resource identified by the resource parameter.
9051: Side Effects:
9052: The following global variables can be set:
9053: ssi_error - If an unrecoverable error occurred this becomes true.
9054: It is up to the caller to initialize this to false
9055: if desired.
9056: ssi_error_resource - If an unrecoverable error occurred, this is the value
9057: of the resource that could not be rendered by the ssi
9058: call.
9059: ssi_error_message - The error string fetched from the ssi response
9060: in the event of an error.

9071: =item scantron_get_correction() :
9072:
9073: Builds the interface screen to interact with the operator to fix a
9074: specific error condition in a specific scanline
9075:
9076: Arguments:
9077: $r - Apache request object
9078: $i - number of the current scanline
9079: $scan_record - hash ref as returned from &scantron_parse_scanline()
9080: $scan_config - hash ref as returned from &get_scantron_config()
9081: $line - full contents of the current scanline
9082: $error - error condition, valid values are
9083: 'incorrectCODE', 'duplicateCODE',
9084: 'doublebubble', 'missingbubble',
9085: 'duplicateID', 'incorrectID'
9086: $arg - extra information needed
9087: For errors:
9088: - duplicateID - paper number that this studentID was seen before on
9089: - duplicateCODE - array ref of the paper numbers this CODE was
9090: seen on before
9091: - incorrectCODE - current incorrect CODE
9092: - doublebubble - array ref of the bubble lines that have double
9093: bubble errors
9094: - missingbubble - array ref of the bubble lines that have missing
9095: bubble errors
9096:
9097: =item scantron_get_maxbubble() :
9098:
9099: Returns the maximum number of bubble lines that are expected to
9100: occur. Does this by walking the selected sequence rendering the
9101: resource and then checking &Apache::lonxml::get_problem_counter()
9102: for what the current value of the problem counter is.
9103:
9104: Caches the results to $env{'form.scantron_maxbubble'},
9105: $env{'form.scantron.bubble_lines.n'},
9106: $env{'form.scantron.first_bubble_line.n'} and
9107: $env{"form.scantron.sub_bubblelines.n"}
9108: which are the total number of bubble, lines, the number of bubble
9109: lines for response n and number of the first bubble line for response n,
9110: and a comma separated list of numbers of bubble lines for sub-questions
9111: (for optionresponse, matchresponse, and rankresponse items), for response n.
9112:
9113:
9114: =item scantron_validate_missingbubbles() :
9115:
9116: Validates all scanlines in the selected file to not have any
9117: answers that don't have bubbles that have not been verified
9118: to be bubble free.
9119:
9120: =item scantron_process_students() :
9121:
9122: Routine that does the actual grading of the bubble sheet information.
9123:
9124: The parsed scanline hash is added to %env
9125:
9126: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9127: foreach resource , with the form data of
9128:
9129: 'submitted' =>'scantron'
9130: 'grade_target' =>'grade',
9131: 'grade_username'=> username of student
9132: 'grade_domain' => domain of student
9133: 'grade_courseid'=> of course
9134: 'grade_symb' => symb of resource to grade
9135:
9136: This triggers a grading pass. The problem grading code takes care
9137: of converting the bubbled letter information (now in %env) into a
9138: valid submission.
9139:
9140: =item scantron_upload_scantron_data() :
9141:
9142: Creates the screen for adding a new bubble sheet data file to a course.
9143:
9144: =item scantron_upload_scantron_data_save() :
9145:
9146: Adds a provided bubble information data file to the course if user
9147: has the correct privileges to do so.
9148:
9149: =item valid_file() :
9150:
9151: Validates that the requested bubble data file exists in the course.
9152:
9153: =item scantron_download_scantron_data() :
9154:
9155: Shows a list of the three internal files (original, corrected,
9156: skipped) for a specific bubble sheet data file that exists in the
9157: course.
9158:
9159: =item scantron_validate_ID() :
9160:
9161: Validates all scanlines in the selected file to not have any
9162: invalid or underspecified student IDs
