5818: 'scanline' refers to the full line of characters

5821: 'bubble line' refers to the data
5822: representing the line of bubbles that are on the physical bubblesheet
5823:
5824:
5825: The overall process is that a scanned in bubblesheet data is uploaded
5826: into a course. When a user wants to grade, they select a
5827: sequence/folder of resources, a file of bubblesheet info, and pick
5828: one of the predefined configurations for what each scanline looks
5829: like.
5830:
5831: Next each scanline is checked for any errors of either 'missing
5832: bubbles' (it's an error because it may have been mis-scanned
5833: because too light bubbling), 'double bubble' (each bubble line should

11670: Apache::grades
11671:
11672: =head1 SYNOPSIS
11673:
11674: Handles the viewing of grades.
11675:
11676: This is part of the LearningOnline Network with CAPA project
11677: described at http://www.lon-capa.org.
11678:
11679: =head1 OVERVIEW
11680:
11681: Do an ssi with retries:
11682: While I'd love to factor out this with the version in lonprintout,
11683: 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
11684: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11685:
11686: At least the logic that drives this has been pulled out into loncommon.
11687:
11688:
11689:
11690: ssi_with_retries - Does the server side include of a resource.
11691: if the ssi call returns an error we'll retry it up to
11692: the number of times requested by the caller.
11693: If we still have a problem, no text is appended to the
11694: output and we set some global variables.
11695: to indicate to the caller an SSI error occurred.
11696: All of this is supposed to deal with the issues described
11697: in LON-CAPA BZ 5631 see:
11698: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11699: by informing the user that this happened.
11700:
11701: Parameters:
11702: resource - The resource to include. This is passed directly, without
11703: interpretation to lonnet::ssi.
11704: form - The form hash parameters that guide the interpretation of the resource
11705:
11706: retries - Number of retries allowed before giving up completely.
11707: Returns:
11708: On success, returns the rendered resource identified by the resource parameter.
11709: Side Effects:
11710: The following global variables can be set:
11711: ssi_error - If an unrecoverable error occurred this becomes true.
11712: It is up to the caller to initialize this to false
11713: if desired.
11714: ssi_error_resource - If an unrecoverable error occurred, this is the value
11715: of the resource that could not be rendered by the ssi
11716: call.
11717: ssi_error_message - The error string fetched from the ssi response
11718: in the event of an error.

11728:
11729: =head1 Routines to display previous version of a Task for a specific student
11730:
11731: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11732: can receive another opportunity. Access to tasks is slot-based. If a slot
11733: requires a proctor to check-in the student, a new version of the Task will
11734: be created when the student is checked in to the new opportunity.
11735:
11736: If a particular student has tried two or more versions of a particular task,
11737: the submission screen provides a user with vgr privileges (e.g., a Course
11738: Coordinator) the ability to display a previous version worked on by the
11739: student. By default, the current version is displayed. If a previous version
11740: has been selected for display, submission data are only shown that pertain
11741: to that particular version, and the interface to submit grades is not shown.
11742:
11743: =over 4
11744:
11745: =item show_previous_task_version()
11746:

11751: symb - unique symb for current instance of resource
11752:
11753: Output: None.
11754:
11755: Side Effects: calls &show_problem() to print version of Task, with
11756: version contained in form item: $env{'form.previousversion'}
11757:
11758: =item choose_task_version_form()
11759:
11760: Displays a web form used to select which version of a student's view of a
11761: Task should be displayed. Either launches a pop-up window, or replaces
11762: content in existing pop-up, or replaces page in main window.
11763:
11764: Inputs: 4
11765: symb - unique symb for current instance of resource
11766: uname - username of student
11767: udom - domain of student

11769: breadcrumbs etc., are displayed
11770:
11771: Output: 4
11772: current - student's current version
11773: displayed - student's version being displayed
11774: result - scalar containing HTML for web form used to switch to
11775: a different version (or a link to close window, if pop-up).
11776: js - javascript for processing selection in versions web form
11777:
11778: Side Effects: None.
11779:
11780: =item previous_display_javascript()
11781:
11782: Inputs: 2
11783: nomenu - 1 if display is in a pop-up window, and hence no menu
11784: breadcrumbs etc., are displayed.
11785: current - student's current version number.
11786:
11787: Output: 1
11788: js - javascript for processing selection in versions web form.

11840: if $nav_error is set to 1 by scantron_get_maxbubble(), the

11845:

11870:
11871: The parsed scanline hash is added to %env
