This is passed directly, without 11171: interpretation to lonnet::ssi. 11172: form - The form hash parameters that guide the interpretation of the resource 11173: 11174: retries - Number of retries allowed before giving up completely. 11175: Returns: 11176: On success, returns the rendered resource identified by the resource parameter. 11177: Side Effects: 11178: The following global variables can be set: 11179: ssi_error - If an unrecoverable error occurred this becomes true. 11180: It is up to the caller to initialize this to false 11181: if desired. 11182: ssi_error_resource - If an unrecoverable error occurred, this is the value 11183: of the resource that could not be rendered by the ssi 11184: call. 11185: ssi_error_message - The error string fetched from the ssi response 11186: in the event of an error. 11187: 11188: 11189: =head1 HANDLER SUBROUTINE 11190: 11191: ssi_with_retries() 11192: 11193: =head1 SUBROUTINES 11194: 11195: =over 11196: 11197: =item scantron_get_correction() : 11198: 11199: Builds the interface screen to interact with the operator to fix a 11200: specific error condition in a specific scanline 11201: 11202: Arguments: 11203: $r - Apache request object 11204: $i - number of the current scanline 11205: $scan_record - hash ref as returned from &scantron_parse_scanline() 11206: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config() 11207: $line - full contents of the current scanline 11208: $error - error condition, valid values are 11209: 'incorrectCODE', 'duplicateCODE', 11210: 'doublebubble', 'missingbubble', 11211: 'duplicateID', 'incorrectID' 11212: $arg - extra information needed 11213: For errors: 11214: - duplicateID - paper number that this studentID was seen before on 11215: - duplicateCODE - array ref of the paper numbers this CODE was 11216: seen on before 11217: - incorrectCODE - current incorrect CODE 11218: - doublebubble - array ref of the bubble lines that have double 11219: bubble errors 11220: - missingbubble - array ref of the bubble lines that have missing 11221: bubble errors 11222: 11223: $randomorder - True if exam folder has randomorder set 11224: $randompick - True if exam folder has randompick set 11225: $respnumlookup - Reference to HASH mapping question numbers in bubble lines 11226: for current line to question number used for same question 11227: in "Master Seqence" (as seen by Course Coordinator). 11228: $startline - Reference to hash where key is question number (0 is first) 11229: and value is number of first bubble line for current student 11230: or code-based randompick and/or randomorder. 11231: 11232: 11233: =item scantron_get_maxbubble() : 11234: 11235: Arguments: 11236: $nav_error - Reference to scalar which is a flag to indicate a 11237: failure to retrieve a navmap object. 11238: if $nav_error is set to 1 by scantron_get_maxbubble(), the 11239: calling routine should trap the error condition and display the warning 11240: found in &navmap_errormsg(). 11241: 11242: $scantron_config - Reference to bubblesheet format configuration hash. 11243: 11244: Returns the maximum number of bubble lines that are expected to 11245: occur.
