1.424 albertel 4853: one of the predefined configurations for what each scanline looks
4854: like.
4855:
4856: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4857: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4858: because too light bubbling), 'double bubble' (each bubble line should

1.424 albertel 4861:
4862: If the CODE option is used that determines the randomization of the

1.424 albertel 4864: username:domain.

9604: =head1 NAME
9605:
9606: Apache::grades
9607:
9608: =head1 SYNOPSIS
9609:
9610: Handles the viewing of grades.
9611:
9612: This is part of the LearningOnline Network with CAPA project
9613: described at http://www.lon-capa.org.
9614:
9615: =head1 OVERVIEW
9616:
9617: Do an ssi with retries:
9618: While I'd love to factor out this with the vesrion in lonprintout,
9619: 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
9620: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9621:
9622: At least the logic that drives this has been pulled out into loncommon.
9623:
9624:
9625:
9626: ssi_with_retries - Does the server side include of a resource.
9627: if the ssi call returns an error we'll retry it up to
9628: the number of times requested by the caller.
9629: If we still have a proble, no text is appended to the
9630: output and we set some global variables.
9631: to indicate to the caller an SSI error occurred.
9632: All of this is supposed to deal with the issues described
9633: in LonCAPA BZ 5631 see:
9634: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9635: by informing the user that this happened.
9636:
9637: Parameters:
9638: resource - The resource to include. This is passed directly, without
9639: interpretation to lonnet::ssi.
9640: form - The form hash parameters that guide the interpretation of the resource
9641:
9642: retries - Number of retries allowed before giving up completely.
9643: Returns:
9644: On success, returns the rendered resource identified by the resource parameter.
9645: Side Effects:
9646: The following global variables can be set:
9647: ssi_error - If an unrecoverable error occurred this becomes true.
9648: It is up to the caller to initialize this to false
9649: if desired.
