This is passed directly, without 10925: interpretation to lonnet::ssi. 10926: form - The form hash parameters that guide the interpretation of the resource 10927: 10928: retries - Number of retries allowed before giving up completely. 10929: Returns: 10930: On success, returns the rendered resource identified by the resource parameter. 10931: Side Effects: 10932: The following global variables can be set: 10933: ssi_error - If an unrecoverable error occurred this becomes true. 10934: It is up to the caller to initialize this to false 10935: if desired. 10936: ssi_error_resource - If an unrecoverable error occurred, this is the value 10937: of the resource that could not be rendered by the ssi 10938: call. 10939: ssi_error_message - The error string fetched from the ssi response 10940: in the event of an error. 10941: 10942: 10943: =head1 HANDLER SUBROUTINE 10944: 10945: ssi_with_retries() 10946: 10947: =head1 SUBROUTINES 10948: 10949: =over 10950: 10951: =item scantron_get_correction() : 10952: 10953: Builds the interface screen to interact with the operator to fix a 10954: specific error condition in a specific scanline 10955: 10956: Arguments: 10957: $r - Apache request object 10958: $i - number of the current scanline 10959: $scan_record - hash ref as returned from &scantron_parse_scanline() 10960: $scan_config - hash ref as returned from &get_scantron_config() 10961: $line - full contents of the current scanline 10962: $error - error condition, valid values are 10963: 'incorrectCODE', 'duplicateCODE', 10964: 'doublebubble', 'missingbubble', 10965: 'duplicateID', 'incorrectID' 10966: $arg - extra information needed 10967: For errors: 10968: - duplicateID - paper number that this studentID was seen before on 10969: - duplicateCODE - array ref of the paper numbers this CODE was 10970: seen on before 10971: - incorrectCODE - current incorrect CODE 10972: - doublebubble - array ref of the bubble lines that have double 10973: bubble errors 10974: - missingbubble - array ref of the bubble lines that have missing 10975: bubble errors 10976: 10977: $randomorder - True if exam folder has randomorder set 10978: $randompick - True if exam folder has randompick set 10979: $respnumlookup - Reference to HASH mapping question numbers in bubble lines 10980: for current line to question number used for same question 10981: in "Master Seqence" (as seen by Course Coordinator). 10982: $startline - Reference to hash where key is question number (0 is first) 10983: and value is number of first bubble line for current student 10984: or code-based randompick and/or randomorder. 10985: 10986: 10987: =item scantron_get_maxbubble() : 10988: 10989: Arguments: 10990: $nav_error - Reference to scalar which is a flag to indicate a 10991: failure to retrieve a navmap object. 10992: if $nav_error is set to 1 by scantron_get_maxbubble(), the 10993: calling routine should trap the error condition and display the warning 10994: found in &navmap_errormsg(). 10995: 10996: $scantron_config - Reference to bubblesheet format configuration hash. 10997: 10998: Returns the maximum number of bubble lines that are expected to 10999: occur.
