This is passed directly, without 11089: interpretation to lonnet::ssi. 11090: form - The form hash parameters that guide the interpretation of the resource 11091: 11092: retries - Number of retries allowed before giving up completely. 11093: Returns: 11094: On success, returns the rendered resource identified by the resource parameter. 11095: Side Effects: 11096: The following global variables can be set: 11097: ssi_error - If an unrecoverable error occurred this becomes true. 11098: It is up to the caller to initialize this to false 11099: if desired. 11100: ssi_error_resource - If an unrecoverable error occurred, this is the value 11101: of the resource that could not be rendered by the ssi 11102: call. 11103: ssi_error_message - The error string fetched from the ssi response 11104: in the event of an error. 11105: 11106: 11107: =head1 HANDLER SUBROUTINE 11108: 11109: ssi_with_retries() 11110: 11111: =head1 SUBROUTINES 11112: 11113: =over 11114: 11115: =item scantron_get_correction() : 11116: 11117: Builds the interface screen to interact with the operator to fix a 11118: specific error condition in a specific scanline 11119: 11120: Arguments: 11121: $r - Apache request object 11122: $i - number of the current scanline 11123: $scan_record - hash ref as returned from &scantron_parse_scanline() 11124: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config() 11125: $line - full contents of the current scanline 11126: $error - error condition, valid values are 11127: 'incorrectCODE', 'duplicateCODE', 11128: 'doublebubble', 'missingbubble', 11129: 'duplicateID', 'incorrectID' 11130: $arg - extra information needed 11131: For errors: 11132: - duplicateID - paper number that this studentID was seen before on 11133: - duplicateCODE - array ref of the paper numbers this CODE was 11134: seen on before 11135: - incorrectCODE - current incorrect CODE 11136: - doublebubble - array ref of the bubble lines that have double 11137: bubble errors 11138: - missingbubble - array ref of the bubble lines that have missing 11139: bubble errors 11140: 11141: $randomorder - True if exam folder has randomorder set 11142: $randompick - True if exam folder has randompick set 11143: $respnumlookup - Reference to HASH mapping question numbers in bubble lines 11144: for current line to question number used for same question 11145: in "Master Seqence" (as seen by Course Coordinator). 11146: $startline - Reference to hash where key is question number (0 is first) 11147: and value is number of first bubble line for current student 11148: or code-based randompick and/or randomorder. 11149: 11150: 11151: =item scantron_get_maxbubble() : 11152: 11153: Arguments: 11154: $nav_error - Reference to scalar which is a flag to indicate a 11155: failure to retrieve a navmap object. 11156: if $nav_error is set to 1 by scantron_get_maxbubble(), the 11157: calling routine should trap the error condition and display the warning 11158: found in &navmap_errormsg(). 11159: 11160: $scantron_config - Reference to bubblesheet format configuration hash. 11161: 11162: Returns the maximum number of bubble lines that are expected to 11163: occur.
