This is passed directly, without 9346: interpretation to lonnet::ssi. 9347: form - The form hash parameters that guide the interpretation of the resource 9348: 9349: retries - Number of retries allowed before giving up completely. 9350: Returns: 9351: On success, returns the rendered resource identified by the resource parameter. 9352: Side Effects: 9353: The following global variables can be set: 9354: ssi_error - If an unrecoverable error occurred this becomes true. 9355: It is up to the caller to initialize this to false 9356: if desired. 9357: ssi_error_resource - If an unrecoverable error occurred, this is the value 9358: of the resource that could not be rendered by the ssi 9359: call. 9360: ssi_error_message - The error string fetched from the ssi response 9361: in the event of an error. 9362: 9363: 9364: =head1 HANDLER SUBROUTINE 9365: 9366: ssi_with_retries() 9367: 9368: =head1 SUBROUTINES 9369: 9370: =over 9371: 9372: =item scantron_get_correction() : 9373: 9374: Builds the interface screen to interact with the operator to fix a 9375: specific error condition in a specific scanline 9376: 9377: Arguments: 9378: $r - Apache request object 9379: $i - number of the current scanline 9380: $scan_record - hash ref as returned from &scantron_parse_scanline() 9381: $scan_config - hash ref as returned from &get_scantron_config() 9382: $line - full contents of the current scanline 9383: $error - error condition, valid values are 9384: 'incorrectCODE', 'duplicateCODE', 9385: 'doublebubble', 'missingbubble', 9386: 'duplicateID', 'incorrectID' 9387: $arg - extra information needed 9388: For errors: 9389: - duplicateID - paper number that this studentID was seen before on 9390: - duplicateCODE - array ref of the paper numbers this CODE was 9391: seen on before 9392: - incorrectCODE - current incorrect CODE 9393: - doublebubble - array ref of the bubble lines that have double 9394: bubble errors 9395: - missingbubble - array ref of the bubble lines that have missing 9396: bubble errors 9397: 9398: =item scantron_get_maxbubble() : 9399: 9400: Arguments: 9401: $nav_error - Reference to scalar which is a flag to indicate a 9402: failure to retrieve a navmap object. 9403: if $nav_error is set to 1 by scantron_get_maxbubble(), the 9404: calling routine should trap the error condition and display the warning 9405: found in &navmap_errormsg(). 9406: 9407: Returns the maximum number of bubble lines that are expected to 9408: occur.
