10047: =head1 NAME
10048:
10049: Apache::grades
10050:
10051: =head1 SYNOPSIS
10052:
10053: Handles the viewing of grades.
10054:
10055: This is part of the LearningOnline Network with CAPA project
10056: described at http://www.lon-capa.org.
10057:
10058: =head1 OVERVIEW
10059:
10060: Do an ssi with retries:
10061: While I'd love to factor out this with the vesrion in lonprintout,
10062: 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
10063: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10064:
10065: At least the logic that drives this has been pulled out into loncommon.
10066:
10067:
10068:
10069: ssi_with_retries - Does the server side include of a resource.
10070: if the ssi call returns an error we'll retry it up to
10071: the number of times requested by the caller.
10072: If we still have a proble, no text is appended to the
10073: output and we set some global variables.
10074: to indicate to the caller an SSI error occurred.
10075: All of this is supposed to deal with the issues described
10076: in LonCAPA BZ 5631 see:
10077: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10078: by informing the user that this happened.
10079:
10080: Parameters:
10081: resource - The resource to include. This is passed directly, without
10082: interpretation to lonnet::ssi.
10083: form - The form hash parameters that guide the interpretation of the resource
10084:
10085: retries - Number of retries allowed before giving up completely.
10086: Returns:
10087: On success, returns the rendered resource identified by the resource parameter.
10088: Side Effects:
10089: The following global variables can be set:
10090: ssi_error - If an unrecoverable error occurred this becomes true.
10091: It is up to the caller to initialize this to false
10092: if desired.
10093: ssi_error_resource - If an unrecoverable error occurred, this is the value
10094: of the resource that could not be rendered by the ssi
10095: call.
10096: ssi_error_message - The error string fetched from the ssi response
10097: in the event of an error.

10114: $r - Apache request object
