This is passed directly, without 11337: interpretation to lonnet::ssi. 11338: form - The form hash parameters that guide the interpretation of the resource 11339: 11340: retries - Number of retries allowed before giving up completely. 11341: Returns: 11342: On success, returns the rendered resource identified by the resource parameter. 11343: Side Effects: 11344: The following global variables can be set: 11345: ssi_error - If an unrecoverable error occurred this becomes true. 11346: It is up to the caller to initialize this to false 11347: if desired. 11348: ssi_error_resource - If an unrecoverable error occurred, this is the value 11349: of the resource that could not be rendered by the ssi 11350: call. 11351: ssi_error_message - The error string fetched from the ssi response 11352: in the event of an error. 11353: 11354: 11355: =head1 HANDLER SUBROUTINE 11356: 11357: ssi_with_retries() 11358: 11359: =head1 SUBROUTINES 11360: 11361: =over 11362: 11363: =item scantron_get_correction() : 11364: 11365: Builds the interface screen to interact with the operator to fix a 11366: specific error condition in a specific scanline 11367: 11368: Arguments: 11369: $r - Apache request object 11370: $i - number of the current scanline 11371: $scan_record - hash ref as returned from &scantron_parse_scanline() 11372: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config() 11373: $line - full contents of the current scanline 11374: $error - error condition, valid values are 11375: 'incorrectCODE', 'duplicateCODE', 11376: 'doublebubble', 'missingbubble', 11377: 'duplicateID', 'incorrectID' 11378: $arg - extra information needed 11379: For errors: 11380: - duplicateID - paper number that this studentID was seen before on 11381: - duplicateCODE - array ref of the paper numbers this CODE was 11382: seen on before 11383: - incorrectCODE - current incorrect CODE 11384: - doublebubble - array ref of the bubble lines that have double 11385: bubble errors 11386: - missingbubble - array ref of the bubble lines that have missing 11387: bubble errors 11388: 11389: $randomorder - True if exam folder (or a sub-folder) has randomorder set 11390: $randompick - True if exam folder (or a sub-folder) has randompick set 11391: $respnumlookup - Reference to HASH mapping question numbers in bubble lines 11392: for current line to question number used for same question 11393: in "Master Seqence" (as seen by Course Coordinator). 11394: $startline - Reference to hash where key is question number (0 is first) 11395: and value is number of first bubble line for current student 11396: or code-based randompick and/or randomorder. 11397: 11398: 11399: =item scantron_get_maxbubble() : 11400: 11401: Arguments: 11402: $nav_error - Reference to scalar which is a flag to indicate a 11403: failure to retrieve a navmap object. 11404: if $nav_error is set to 1 by scantron_get_maxbubble(), the 11405: calling routine should trap the error condition and display the warning 11406: found in &navmap_errormsg(). 11407: 11408: $scantron_config - Reference to bubblesheet format configuration hash. 11409: 11410: Returns the maximum number of bubble lines that are expected to 11411: occur.
