This is passed directly, without 9405: interpretation to lonnet::ssi. 9406: form - The form hash parameters that guide the interpretation of the resource 9407: 9408: retries - Number of retries allowed before giving up completely. 9409: Returns: 9410: On success, returns the rendered resource identified by the resource parameter. 9411: Side Effects: 9412: The following global variables can be set: 9413: ssi_error - If an unrecoverable error occurred this becomes true. 9414: It is up to the caller to initialize this to false 9415: if desired. 9416: ssi_error_resource - If an unrecoverable error occurred, this is the value 9417: of the resource that could not be rendered by the ssi 9418: call. 9419: ssi_error_message - The error string fetched from the ssi response 9420: in the event of an error. 9421: 9422: 9423: =head1 HANDLER SUBROUTINE 9424: 9425: ssi_with_retries() 9426: 9427: =head1 SUBROUTINES 9428: 9429: =over 9430: 9431: =item scantron_get_correction() : 9432: 9433: Builds the interface screen to interact with the operator to fix a 9434: specific error condition in a specific scanline 9435: 9436: Arguments: 9437: $r - Apache request object 9438: $i - number of the current scanline 9439: $scan_record - hash ref as returned from &scantron_parse_scanline() 9440: $scan_config - hash ref as returned from &get_scantron_config() 9441: $line - full contents of the current scanline 9442: $error - error condition, valid values are 9443: 'incorrectCODE', 'duplicateCODE', 9444: 'doublebubble', 'missingbubble', 9445: 'duplicateID', 'incorrectID' 9446: $arg - extra information needed 9447: For errors: 9448: - duplicateID - paper number that this studentID was seen before on 9449: - duplicateCODE - array ref of the paper numbers this CODE was 9450: seen on before 9451: - incorrectCODE - current incorrect CODE 9452: - doublebubble - array ref of the bubble lines that have double 9453: bubble errors 9454: - missingbubble - array ref of the bubble lines that have missing 9455: bubble errors 9456: 9457: =item scantron_get_maxbubble() : 9458: 9459: Arguments: 9460: $nav_error - Reference to scalar which is a flag to indicate a 9461: failure to retrieve a navmap object. 9462: if $nav_error is set to 1 by scantron_get_maxbubble(), the 9463: calling routine should trap the error condition and display the warning 9464: found in &navmap_errormsg(). 9465: 9466: Returns the maximum number of bubble lines that are expected to 9467: occur.
