HEAD
Optimized/standarized screen output for first grading screen ("Manual Grading/View Submissions"):
- Replaced special styles with standard fieldsets
- Removed now unused styles from loncommon.pm
- Excluded section preselection from output
These changes also restore the screen layout for the radiobuttons which have moved right to the selection boxes due to new styles.

4635: =head1 Bubble sheet grading routines
4636:
4637: For this documentation:
4638:
4639: 'scanline' refers to the full line of characters
4640: from the file that we are parsing that represents one entire sheet
4641:
4642: 'bubble line' refers to the data
4643: representing the line of bubbles that are on the physical bubble sheet
4644:
4645:
4646: The overall process is that a scanned in bubble sheet data is uploaded
4647: into a course. When a user wants to grade, they select a
4648: sequence/folder of resources, a file of bubble sheet info, and pick
4649: one of the predefined configurations for what each scanline looks
4650: like.
4651:
4652: Next each scanline is checked for any errors of either 'missing
4653: bubbles' (it's an error because it may have been mis-scanned
4654: because too light bubbling), 'double bubble' (each bubble line should
4655: have no more that one letter picked), invalid or duplicated CODE,
4656: invalid student ID
4657:
4658: If the CODE option is used that determines the randomization of the
4659: homework problems, either way the student ID is looked up into a
4660: username:domain.
4661:
4662: During the validation phase the instructor can choose to skip scanlines.
4663:
4664: After the validation phase, there are now 3 bubble sheet files
4665:
4666: scantron_original_filename (unmodified original file)
4667: scantron_corrected_filename (file where the corrected information has replaced the original information)
4668: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4669:
4670: Also there is a separate hash nohist_scantrondata that contains extra
4671: correction information that isn't representable in the bubble sheet
4672: file (see &scantron_getfile() for more information)
4673:
4674: After all scanlines are either valid, marked as valid or skipped, then
4675: foreach line foreach problem in the picked sequence, an ssi request is
4676: made that simulates a user submitting their selected letter(s) against
4677: the homework problem.

8937: =head1 NAME
8938:
8939: Apache::grades
8940:
8941: =head1 SYNOPSIS
8942:
8943: Handles the viewing of grades.
8944:
8945: This is part of the LearningOnline Network with CAPA project
8946: described at http://www.lon-capa.org.
8947:
8948: =head1 OVERVIEW
8949:
8950: Do an ssi with retries:
8951: While I'd love to factor out this with the vesrion in lonprintout,
8952: 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
8953: I'm not quite ready to invent (e.g. an ssi_with_retry object).
8954:
8955: At least the logic that drives this has been pulled out into loncommon.
8956:
8957:
8958:
8959: ssi_with_retries - Does the server side include of a resource.
8960: if the ssi call returns an error we'll retry it up to
8961: the number of times requested by the caller.
8962: If we still have a proble, no text is appended to the
8963: output and we set some global variables.
8964: to indicate to the caller an SSI error occurred.
8965: All of this is supposed to deal with the issues described
8966: in LonCAPA BZ 5631 see:
8967: http://bugs.lon-capa.org/show_bug.cgi?id=5631
8968: by informing the user that this happened.
8969:
8970: Parameters:
8971: resource - The resource to include. This is passed directly, without
8972: interpretation to lonnet::ssi.
8973: form - The form hash parameters that guide the interpretation of the resource
8974:
8975: retries - Number of retries allowed before giving up completely.
8976: Returns:
8977: On success, returns the rendered resource identified by the resource parameter.
8978: Side Effects:
8979: The following global variables can be set:
8980: ssi_error - If an unrecoverable error occurred this becomes true.
8981: It is up to the caller to initialize this to false
8982: if desired.
8983: ssi_error_resource - If an unrecoverable error occurred, this is the value
8984: of the resource that could not be rendered by the ssi
8985: call.
8986: ssi_error_message - The error string fetched from the ssi response
8987: in the event of an error.

9006: $scan_record - hash ref as returned from &scantron_parse_scanline()
9007: $scan_config - hash ref as returned from &get_scantron_config()
9008: $line - full contents of the current scanline
9009: $error - error condition, valid values are
9010: 'incorrectCODE', 'duplicateCODE',

9012: 'duplicateID', 'incorrectID'
9013: $arg - extra information needed
9014: For errors:
9015: - duplicateID - paper number that this studentID was seen before on
9016: - duplicateCODE - array ref of the paper numbers this CODE was
9017: seen on before
9018: - incorrectCODE - current incorrect CODE
9019: - doublebubble - array ref of the bubble lines that have double
