10161: =head1 NAME
10162:
10163: Apache::grades
10164:
10165: =head1 SYNOPSIS
10166:
10167: Handles the viewing of grades.
10168:
10169: This is part of the LearningOnline Network with CAPA project
10170: described at http://www.lon-capa.org.
10171:
10172: =head1 OVERVIEW
10173:
10174: Do an ssi with retries:
10175: While I'd love to factor out this with the vesrion in lonprintout,
10176: 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
10177: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10178:
10179: At least the logic that drives this has been pulled out into loncommon.
10180:
10181:
10182:
10183: ssi_with_retries - Does the server side include of a resource.
10184: if the ssi call returns an error we'll retry it up to
10185: the number of times requested by the caller.
10186: If we still have a proble, no text is appended to the
10187: output and we set some global variables.
10188: to indicate to the caller an SSI error occurred.
10189: All of this is supposed to deal with the issues described
10190: in LonCAPA BZ 5631 see:
10191: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10192: by informing the user that this happened.
10193:
10194: Parameters:
10195: resource - The resource to include. This is passed directly, without
10196: interpretation to lonnet::ssi.
10197: form - The form hash parameters that guide the interpretation of the resource
10198:
10199: retries - Number of retries allowed before giving up completely.
10200: Returns:
10201: On success, returns the rendered resource identified by the resource parameter.
10202: Side Effects:
10203: The following global variables can be set:
10204: ssi_error - If an unrecoverable error occurred this becomes true.
10205: It is up to the caller to initialize this to false
10206: if desired.
10207: ssi_error_resource - If an unrecoverable error occurred, this is the value
10208: of the resource that could not be rendered by the ssi
10209: call.
10210: ssi_error_message - The error string fetched from the ssi response
10211: in the event of an error.
