This is passed directly, without 9403: interpretation to lonnet::ssi. 9404: form - The form hash parameters that guide the interpretation of the resource 9405: 9406: retries - Number of retries allowed before giving up completely. 9407: Returns: 9408: On success, returns the rendered resource identified by the resource parameter. 9409: Side Effects: 9410: The following global variables can be set: 9411: ssi_error - If an unrecoverable error occurred this becomes true. 9412: It is up to the caller to initialize this to false 9413: if desired. 9414: ssi_error_resource - If an unrecoverable error occurred, this is the value 9415: of the resource that could not be rendered by the ssi 9416: call. 9417: ssi_error_message - The error string fetched from the ssi response 9418: in the event of an error. 9419: 9420: 9421: =head1 HANDLER SUBROUTINE 9422: 9423: ssi_with_retries() 9424: 9425: =head1 SUBROUTINES 9426: 9427: =over 9428: 9429: =item scantron_get_correction() : 9430: 9431: Builds the interface screen to interact with the operator to fix a 9432: specific error condition in a specific scanline 9433: 9434: Arguments: 9435: $r - Apache request object 9436: $i - number of the current scanline 9437: $scan_record - hash ref as returned from &scantron_parse_scanline() 9438: $scan_config - hash ref as returned from &get_scantron_config() 9439: $line - full contents of the current scanline 9440: $error - error condition, valid values are 9441: 'incorrectCODE', 'duplicateCODE', 9442: 'doublebubble', 'missingbubble', 9443: 'duplicateID', 'incorrectID' 9444: $arg - extra information needed 9445: For errors: 9446: - duplicateID - paper number that this studentID was seen before on 9447: - duplicateCODE - array ref of the paper numbers this CODE was 9448: seen on before 9449: - incorrectCODE - current incorrect CODE 9450: - doublebubble - array ref of the bubble lines that have double 9451: bubble errors 9452: - missingbubble - array ref of the bubble lines that have missing 9453: bubble errors 9454: 9455: =item scantron_get_maxbubble() : 9456: 9457: Arguments: 9458: $nav_error - Reference to scalar which is a flag to indicate a 9459: failure to retrieve a navmap object. 9460: if $nav_error is set to 1 by scantron_get_maxbubble(), the 9461: calling routine should trap the error condition and display the warning 9462: found in &navmap_errormsg(). 9463: 9464: Returns the maximum number of bubble lines that are expected to 9465: occur.
