# Do an ssi with retries:
# While I'd love to factor out this with the vesrion in lonprintout,
# 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
# I'm not quite ready to invent (e.g. an ssi_with_retry object).
#
# At least the logic that drives this has been pulled out into loncommon.


#
# ssi_with_retries - Does the server side include of a resource.
# if the ssi call returns an error we'll retry it up to
# the number of times requested by the caller.
# If we still have a proble, no text is appended to the
# output and we set some global variables.
# to indicate to the caller an SSI error occurred.
# All of this is supposed to deal with the issues described
# in LonCAPA BZ 5631 see:
# http://bugs.lon-capa.org/show_bug.cgi?id=5631
# by informing the user that this happened.
#
# Parameters:
# resource - The resource to include. This is passed directly, without
# interpretation to lonnet::ssi.
# form - The form hash parameters that guide the interpretation of the resource
#
# retries - Number of retries allowed before giving up completely.
# Returns:
# On success, returns the rendered resource identified by the resource parameter.
# Side Effects:
# The following global variables can be set:
# ssi_error - If an unrecoverable error occurred this becomes true.
# It is up to the caller to initialize this to false
# if desired.
# ssi_error_resource - If an unrecoverable error occurred, this is the value
# of the resource that could not be rendered by the ssi
# call.
# ssi_error_message - The error string fetched from the ssi response
# in the event of an error.

=item scantron_get_maxbubble

Returns the maximum number of bubble lines that are expected to
occur. Does this by walking the selected sequence rendering the
resource and then checking &Apache::lonxml::get_problem_counter()
for what the current value of the problem counter is.

Caches the results to $env{'form.scantron_maxbubble'},
$env{'form.scantron.bubble_lines.n'},
$env{'form.scantron.first_bubble_line.n'} and
$env{"form.scantron.sub_bubblelines.n"}
which are the total number of bubble, lines, the number of bubble
lines for response n and number of the first bubble line for response n,
and a comma separated list of numbers of bubble lines for sub-questions
(for optionresponse, matchresponse, and rankresponse items), for response n.

	=head1 NAME

	Apache::grades

	=head1 SYNOPSIS

	Handles the viewing of grades.

	This is part of the LearningOnline Network with CAPA project
	described at http://www.lon-capa.org.

	=head1 OVERVIEW

	Do an ssi with retries:
	While I'd love to factor out this with the version in lonprintout,
	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
	I'm not quite ready to invent (e.g. an ssi_with_retry object).

	At least the logic that drives this has been pulled out into loncommon.



	ssi_with_retries - Does the server side include of a resource.
	if the ssi call returns an error we'll retry it up to
	the number of times requested by the caller.
	If we still have a problem, no text is appended to the
	output and we set some global variables.
	to indicate to the caller an SSI error occurred.
	All of this is supposed to deal with the issues described
	in LON-CAPA BZ 5631 see:
	http://bugs.lon-capa.org/show_bug.cgi?id=5631
	by informing the user that this happened.

	Parameters:
	resource - The resource to include. This is passed directly, without
	interpretation to lonnet::ssi.
	form - The form hash parameters that guide the interpretation of the resource

	retries - Number of retries allowed before giving up completely.
	Returns:
	On success, returns the rendered resource identified by the resource parameter.
	Side Effects:
	The following global variables can be set:
	ssi_error - If an unrecoverable error occurred this becomes true.
	It is up to the caller to initialize this to false
	if desired.
	ssi_error_resource - If an unrecoverable error occurred, this is the value
	of the resource that could not be rendered by the ssi
	call.
	ssi_error_message - The error string fetched from the ssi response
	in the event of an error.

	ssi_with_retries()

	=head1 SUBROUTINES

	=over

	=head1 Routines to display previous version of a Task for a specific student

	Tasks are graded pass/fail. Students who have yet to pass a particular Task
	can receive another opportunity. Access to tasks is slot-based. If a slot
	requires a proctor to check-in the student, a new version of the Task will
	be created when the student is checked in to the new opportunity.

	If a particular student has tried two or more versions of a particular task,
	the submission screen provides a user with vgr privileges (e.g., a Course
	Coordinator) the ability to display a previous version worked on by the
	student. By default, the current version is displayed. If a previous version
	has been selected for display, submission data are only shown that pertain
	to that particular version, and the interface to submit grades is not shown.

	=over 4

	=item show_previous_task_version()

	Displays a specified version of a student's Task, as the student sees it.

	Inputs: 2
	request - request object
	symb - unique symb for current instance of resource

	Output: None.

	Side Effects: calls &show_problem() to print version of Task, with
	version contained in form item: $env{'form.previousversion'}

	=item choose_task_version_form()

	Displays a web form used to select which version of a student's view of a
	Task should be displayed. Either launches a pop-up window, or replaces
	content in existing pop-up, or replaces page in main window.

	Inputs: 4
	symb - unique symb for current instance of resource
	uname - username of student
	udom - domain of student
	nomenu - 1 if display is in a pop-up window, and hence no menu
	breadcrumbs etc., are displayed

	Output: 4
	current - student's current version
	displayed - student's version being displayed
	result - scalar containing HTML for web form used to switch to
	a different version (or a link to close window, if pop-up).
	js - javascript for processing selection in versions web form

	Side Effects: None.

	=item previous_display_javascript()

	Inputs: 2
	nomenu - 1 if display is in a pop-up window, and hence no menu
	breadcrumbs etc., are displayed.
	current - student's current version number.

	Output: 1
	js - javascript for processing selection in versions web form.

	Side Effects: None.

	=head1 Routines to process bubblesheet data.

	=over 4

	=item scantron_get_correction() :

	Builds the interface screen to interact with the operator to fix a
	specific error condition in a specific scanline

	Arguments:
	$r - Apache request object
	$i - number of the current scanline
	$scan_record - hash ref as returned from &scantron_parse_scanline()
	$scan_config - hash ref as returned from &get_scantron_config()
	$line - full contents of the current scanline
	$error - error condition, valid values are
	'incorrectCODE', 'duplicateCODE',
	'doublebubble', 'missingbubble',
	'duplicateID', 'incorrectID'
	$arg - extra information needed
	For errors:
	- duplicateID - paper number that this studentID was seen before on
	- duplicateCODE - array ref of the paper numbers this CODE was
	seen on before
	- incorrectCODE - current incorrect CODE
	- doublebubble - array ref of the bubble lines that have double
	bubble errors
	- missingbubble - array ref of the bubble lines that have missing
	bubble errors

	$randomorder - True if exam folder has randomorder set
	$randompick - True if exam folder has randompick set
	$respnumlookup - Reference to HASH mapping question numbers in bubble lines
	for current line to question number used for same question
	in "Master Seqence" (as seen by Course Coordinator).
	$startline - Reference to hash where key is question number (0 is first)
	and value is number of first bubble line for current student
	or code-based randompick and/or randomorder.



	=item scantron_get_maxbubble() :

	Arguments:
	$nav_error - Reference to scalar which is a flag to indicate a
	failure to retrieve a navmap object.
	if $nav_error is set to 1 by scantron_get_maxbubble(), the
	calling routine should trap the error condition and display the warning
	found in &navmap_errormsg().

	$scantron_config - Reference to bubblesheet format configuration hash.

	Returns the maximum number of bubble lines that are expected to
	occur. Does this by walking the selected sequence rendering the
	resource and then checking &Apache::lonxml::get_problem_counter()
	for what the current value of the problem counter is.

	Caches the results to $env{'form.scantron_maxbubble'},
	$env{'form.scantron.bubble_lines.n'},
	$env{'form.scantron.first_bubble_line.n'} and
	$env{"form.scantron.sub_bubblelines.n"}
	which are the total number of bubble lines, the number of bubble
	lines for response n and number of the first bubble line for response n,
	and a comma separated list of numbers of bubble lines for sub-questions
	(for optionresponse, matchresponse, and rankresponse items), for response n.


	=item scantron_validate_missingbubbles() :

	Validates all scanlines in the selected file to not have any
	answers that don't have bubbles that have not been verified
	to be bubble free.

	=item scantron_process_students() :

	Routine that does the actual grading of the bubblesheet information.

	The parsed scanline hash is added to %env

	Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
	foreach resource , with the form data of

	'submitted' =>'scantron'
	'grade_target' =>'grade',
	'grade_username'=> username of student
	'grade_domain' => domain of student
	'grade_courseid'=> of course
	'grade_symb' => symb of resource to grade

	This triggers a grading pass. The problem grading code takes care
	of converting the bubbled letter information (now in %env) into a
	valid submission.

	=item scantron_upload_scantron_data() :

	Creates the screen for adding a new bubblesheet data file to a course.

	=item scantron_upload_scantron_data_save() :

	Adds a provided bubble information data file to the course if user
	has the correct privileges to do so.

	=item valid_file() :

	Validates that the requested bubble data file exists in the course.

	=item scantron_download_scantron_data() :

	Shows a list of the three internal files (original, corrected,
	skipped) for a specific bubblesheet data file that exists in the
	course.

	=item scantron_validate_ID() :

	Validates all scanlines in the selected file to not have any
	invalid or underspecified student/employee IDs

	=item navmap_errormsg() :

	Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
	Should be called whenever the request to instantiate a navmap object fails.
