This is passed directly, without 10924: interpretation to lonnet::ssi. 10925: form - The form hash parameters that guide the interpretation of the resource 10926: 10927: retries - Number of retries allowed before giving up completely. 10928: Returns: 10929: On success, returns the rendered resource identified by the resource parameter. 10930: Side Effects: 10931: The following global variables can be set: 10932: ssi_error - If an unrecoverable error occurred this becomes true. 10933: It is up to the caller to initialize this to false 10934: if desired. 10935: ssi_error_resource - If an unrecoverable error occurred, this is the value 10936: of the resource that could not be rendered by the ssi 10937: call. 10938: ssi_error_message - The error string fetched from the ssi response 10939: in the event of an error. 10940: 10941: 10942: =head1 HANDLER SUBROUTINE 10943: 10944: ssi_with_retries() 10945: 10946: =head1 SUBROUTINES 10947: 10948: =over 10949: 10950: =item scantron_get_correction() : 10951: 10952: Builds the interface screen to interact with the operator to fix a 10953: specific error condition in a specific scanline 10954: 10955: Arguments: 10956: $r - Apache request object 10957: $i - number of the current scanline 10958: $scan_record - hash ref as returned from &scantron_parse_scanline() 10959: $scan_config - hash ref as returned from &get_scantron_config() 10960: $line - full contents of the current scanline 10961: $error - error condition, valid values are 10962: 'incorrectCODE', 'duplicateCODE', 10963: 'doublebubble', 'missingbubble', 10964: 'duplicateID', 'incorrectID' 10965: $arg - extra information needed 10966: For errors: 10967: - duplicateID - paper number that this studentID was seen before on 10968: - duplicateCODE - array ref of the paper numbers this CODE was 10969: seen on before 10970: - incorrectCODE - current incorrect CODE 10971: - doublebubble - array ref of the bubble lines that have double 10972: bubble errors 10973: - missingbubble - array ref of the bubble lines that have missing 10974: bubble errors 10975: 10976: $randomorder - True if exam folder has randomorder set 10977: $randompick - True if exam folder has randompick set 10978: $respnumlookup - Reference to HASH mapping question numbers in bubble lines 10979: for current line to question number used for same question 10980: in "Master Seqence" (as seen by Course Coordinator). 10981: $startline - Reference to hash where key is question number (0 is first) 10982: and value is number of first bubble line for current student 10983: or code-based randompick and/or randomorder. 10984: 10985: 10986: =item scantron_get_maxbubble() : 10987: 10988: Arguments: 10989: $nav_error - Reference to scalar which is a flag to indicate a 10990: failure to retrieve a navmap object. 10991: if $nav_error is set to 1 by scantron_get_maxbubble(), the 10992: calling routine should trap the error condition and display the warning 10993: found in &navmap_errormsg(). 10994: 10995: $scantron_config - Reference to bubblesheet format configuration hash. 10996: 10997: Returns the maximum number of bubble lines that are expected to 10998: occur.
