This is passed directly, without 11181: interpretation to lonnet::ssi. 11182: form - The form hash parameters that guide the interpretation of the resource 11183: 11184: retries - Number of retries allowed before giving up completely. 11185: Returns: 11186: On success, returns the rendered resource identified by the resource parameter. 11187: Side Effects: 11188: The following global variables can be set: 11189: ssi_error - If an unrecoverable error occurred this becomes true. 11190: It is up to the caller to initialize this to false 11191: if desired. 11192: ssi_error_resource - If an unrecoverable error occurred, this is the value 11193: of the resource that could not be rendered by the ssi 11194: call. 11195: ssi_error_message - The error string fetched from the ssi response 11196: in the event of an error. 11197: 11198: 11199: =head1 HANDLER SUBROUTINE 11200: 11201: ssi_with_retries() 11202: 11203: =head1 SUBROUTINES 11204: 11205: =over 11206: 11207: =item scantron_get_correction() : 11208: 11209: Builds the interface screen to interact with the operator to fix a 11210: specific error condition in a specific scanline 11211: 11212: Arguments: 11213: $r - Apache request object 11214: $i - number of the current scanline 11215: $scan_record - hash ref as returned from &scantron_parse_scanline() 11216: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config() 11217: $line - full contents of the current scanline 11218: $error - error condition, valid values are 11219: 'incorrectCODE', 'duplicateCODE', 11220: 'doublebubble', 'missingbubble', 11221: 'duplicateID', 'incorrectID' 11222: $arg - extra information needed 11223: For errors: 11224: - duplicateID - paper number that this studentID was seen before on 11225: - duplicateCODE - array ref of the paper numbers this CODE was 11226: seen on before 11227: - incorrectCODE - current incorrect CODE 11228: - doublebubble - array ref of the bubble lines that have double 11229: bubble errors 11230: - missingbubble - array ref of the bubble lines that have missing 11231: bubble errors 11232: 11233: $randomorder - True if exam folder has randomorder set 11234: $randompick - True if exam folder has randompick set 11235: $respnumlookup - Reference to HASH mapping question numbers in bubble lines 11236: for current line to question number used for same question 11237: in "Master Seqence" (as seen by Course Coordinator). 11238: $startline - Reference to hash where key is question number (0 is first) 11239: and value is number of first bubble line for current student 11240: or code-based randompick and/or randomorder. 11241: 11242: 11243: =item scantron_get_maxbubble() : 11244: 11245: Arguments: 11246: $nav_error - Reference to scalar which is a flag to indicate a 11247: failure to retrieve a navmap object. 11248: if $nav_error is set to 1 by scantron_get_maxbubble(), the 11249: calling routine should trap the error condition and display the warning 11250: found in &navmap_errormsg(). 11251: 11252: $scantron_config - Reference to bubblesheet format configuration hash. 11253: 11254: Returns the maximum number of bubble lines that are expected to 11255: occur.
