This is passed directly, without 10989: interpretation to lonnet::ssi. 10990: form - The form hash parameters that guide the interpretation of the resource 10991: 10992: retries - Number of retries allowed before giving up completely. 10993: Returns: 10994: On success, returns the rendered resource identified by the resource parameter. 10995: Side Effects: 10996: The following global variables can be set: 10997: ssi_error - If an unrecoverable error occurred this becomes true. 10998: It is up to the caller to initialize this to false 10999: if desired. 11000: ssi_error_resource - If an unrecoverable error occurred, this is the value 11001: of the resource that could not be rendered by the ssi 11002: call. 11003: ssi_error_message - The error string fetched from the ssi response 11004: in the event of an error. 11005: 11006: 11007: =head1 HANDLER SUBROUTINE 11008: 11009: ssi_with_retries() 11010: 11011: =head1 SUBROUTINES 11012: 11013: =over 11014: 11015: =item scantron_get_correction() : 11016: 11017: Builds the interface screen to interact with the operator to fix a 11018: specific error condition in a specific scanline 11019: 11020: Arguments: 11021: $r - Apache request object 11022: $i - number of the current scanline 11023: $scan_record - hash ref as returned from &scantron_parse_scanline() 11024: $scan_config - hash ref as returned from &get_scantron_config() 11025: $line - full contents of the current scanline 11026: $error - error condition, valid values are 11027: 'incorrectCODE', 'duplicateCODE', 11028: 'doublebubble', 'missingbubble', 11029: 'duplicateID', 'incorrectID' 11030: $arg - extra information needed 11031: For errors: 11032: - duplicateID - paper number that this studentID was seen before on 11033: - duplicateCODE - array ref of the paper numbers this CODE was 11034: seen on before 11035: - incorrectCODE - current incorrect CODE 11036: - doublebubble - array ref of the bubble lines that have double 11037: bubble errors 11038: - missingbubble - array ref of the bubble lines that have missing 11039: bubble errors 11040: 11041: $randomorder - True if exam folder has randomorder set 11042: $randompick - True if exam folder has randompick set 11043: $respnumlookup - Reference to HASH mapping question numbers in bubble lines 11044: for current line to question number used for same question 11045: in "Master Seqence" (as seen by Course Coordinator). 11046: $startline - Reference to hash where key is question number (0 is first) 11047: and value is number of first bubble line for current student 11048: or code-based randompick and/or randomorder. 11049: 11050: 11051: =item scantron_get_maxbubble() : 11052: 11053: Arguments: 11054: $nav_error - Reference to scalar which is a flag to indicate a 11055: failure to retrieve a navmap object. 11056: if $nav_error is set to 1 by scantron_get_maxbubble(), the 11057: calling routine should trap the error condition and display the warning 11058: found in &navmap_errormsg(). 11059: 11060: $scantron_config - Reference to bubblesheet format configuration hash. 11061: 11062: Returns the maximum number of bubble lines that are expected to 11063: occur.
