This is passed directly, without 10083: interpretation to lonnet::ssi. 10084: form - The form hash parameters that guide the interpretation of the resource 10085: 10086: retries - Number of retries allowed before giving up completely. 10087: Returns: 10088: On success, returns the rendered resource identified by the resource parameter. 10089: Side Effects: 10090: The following global variables can be set: 10091: ssi_error - If an unrecoverable error occurred this becomes true. 10092: It is up to the caller to initialize this to false 10093: if desired. 10094: ssi_error_resource - If an unrecoverable error occurred, this is the value 10095: of the resource that could not be rendered by the ssi 10096: call. 10097: ssi_error_message - The error string fetched from the ssi response 10098: in the event of an error. 10099: 10100: 10101: =head1 HANDLER SUBROUTINE 10102: 10103: ssi_with_retries() 10104: 10105: =head1 SUBROUTINES 10106: 10107: =over 10108: 10109: =item scantron_get_correction() : 10110: 10111: Builds the interface screen to interact with the operator to fix a 10112: specific error condition in a specific scanline 10113: 10114: Arguments: 10115: $r - Apache request object 10116: $i - number of the current scanline 10117: $scan_record - hash ref as returned from &scantron_parse_scanline() 10118: $scan_config - hash ref as returned from &get_scantron_config() 10119: $line - full contents of the current scanline 10120: $error - error condition, valid values are 10121: 'incorrectCODE', 'duplicateCODE', 10122: 'doublebubble', 'missingbubble', 10123: 'duplicateID', 'incorrectID' 10124: $arg - extra information needed 10125: For errors: 10126: - duplicateID - paper number that this studentID was seen before on 10127: - duplicateCODE - array ref of the paper numbers this CODE was 10128: seen on before 10129: - incorrectCODE - current incorrect CODE 10130: - doublebubble - array ref of the bubble lines that have double 10131: bubble errors 10132: - missingbubble - array ref of the bubble lines that have missing 10133: bubble errors 10134: 10135: =item scantron_get_maxbubble() : 10136: 10137: Arguments: 10138: $nav_error - Reference to scalar which is a flag to indicate a 10139: failure to retrieve a navmap object. 10140: if $nav_error is set to 1 by scantron_get_maxbubble(), the 10141: calling routine should trap the error condition and display the warning 10142: found in &navmap_errormsg(). 10143: 10144: $scantron_config - Reference to bubblesheet format configuration hash. 10145: 10146: Returns the maximum number of bubble lines that are expected to 10147: occur.
