9601: =head1 NAME
9602:
9603: Apache::grades
9604:
9605: =head1 SYNOPSIS
9606:
9607: Handles the viewing of grades.
9608:
9609: This is part of the LearningOnline Network with CAPA project
9610: described at http://www.lon-capa.org.
9611:
9612: =head1 OVERVIEW
9613:
9614: Do an ssi with retries:
9615: While I'd love to factor out this with the vesrion in lonprintout,
9616: 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
9617: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9618:
9619: At least the logic that drives this has been pulled out into loncommon.
9620:
9621:
9622:
9623: ssi_with_retries - Does the server side include of a resource.
9624: if the ssi call returns an error we'll retry it up to
9625: the number of times requested by the caller.
9626: If we still have a proble, no text is appended to the
9627: output and we set some global variables.
9628: to indicate to the caller an SSI error occurred.
9629: All of this is supposed to deal with the issues described
9630: in LonCAPA BZ 5631 see:
9631: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9632: by informing the user that this happened.
9633:
9634: Parameters:
9635: resource - The resource to include. This is passed directly, without
9636: interpretation to lonnet::ssi.
9637: form - The form hash parameters that guide the interpretation of the resource
9638:
9639: retries - Number of retries allowed before giving up completely.
9640: Returns:
9641: On success, returns the rendered resource identified by the resource parameter.
9642: Side Effects:
9643: The following global variables can be set:
9644: ssi_error - If an unrecoverable error occurred this becomes true.
9645: It is up to the caller to initialize this to false
9646: if desired.
9647: ssi_error_resource - If an unrecoverable error occurred, this is the value
9648: of the resource that could not be rendered by the ssi
