This is passed directly, without 9395: interpretation to lonnet::ssi. 9396: form - The form hash parameters that guide the interpretation of the resource 9397: 9398: retries - Number of retries allowed before giving up completely. 9399: Returns: 9400: On success, returns the rendered resource identified by the resource parameter. 9401: Side Effects: 9402: The following global variables can be set: 9403: ssi_error - If an unrecoverable error occurred this becomes true. 9404: It is up to the caller to initialize this to false 9405: if desired. 9406: ssi_error_resource - If an unrecoverable error occurred, this is the value 9407: of the resource that could not be rendered by the ssi 9408: call. 9409: ssi_error_message - The error string fetched from the ssi response 9410: in the event of an error. 9411: 9412: 9413: =head1 HANDLER SUBROUTINE 9414: 9415: ssi_with_retries() 9416: 9417: =head1 SUBROUTINES 9418: 9419: =over 9420: 9421: =item scantron_get_correction() : 9422: 9423: Builds the interface screen to interact with the operator to fix a 9424: specific error condition in a specific scanline 9425: 9426: Arguments: 9427: $r - Apache request object 9428: $i - number of the current scanline 9429: $scan_record - hash ref as returned from &scantron_parse_scanline() 9430: $scan_config - hash ref as returned from &get_scantron_config() 9431: $line - full contents of the current scanline 9432: $error - error condition, valid values are 9433: 'incorrectCODE', 'duplicateCODE', 9434: 'doublebubble', 'missingbubble', 9435: 'duplicateID', 'incorrectID' 9436: $arg - extra information needed 9437: For errors: 9438: - duplicateID - paper number that this studentID was seen before on 9439: - duplicateCODE - array ref of the paper numbers this CODE was 9440: seen on before 9441: - incorrectCODE - current incorrect CODE 9442: - doublebubble - array ref of the bubble lines that have double 9443: bubble errors 9444: - missingbubble - array ref of the bubble lines that have missing 9445: bubble errors 9446: 9447: =item scantron_get_maxbubble() : 9448: 9449: Arguments: 9450: $nav_error - Reference to scalar which is a flag to indicate a 9451: failure to retrieve a navmap object. 9452: if $nav_error is set to 1 by scantron_get_maxbubble(), the 9453: calling routine should trap the error condition and display the warning 9454: found in &navmap_errormsg(). 9455: 9456: Returns the maximum number of bubble lines that are expected to 9457: occur.
