- Starting with lonnet.pm rev 1.981, default for &lonnet::delenv() has been to \Q escape arg in regexp used to identify items in environment to delete.
  - No longer need to escape special characters in arg passed to lonnet::delenv().
- Call to lonnet::delenv() in rat/lonuserstate now includes second arg, because in this case first arg is to be treated as a regexp (so \Q escape is not wanted).

This is passed directly, without 9045: interpretation to lonnet::ssi. 9046: form - The form hash parameters that guide the interpretation of the resource 9047: 9048: retries - Number of retries allowed before giving up completely. 9049: Returns: 9050: On success, returns the rendered resource identified by the resource parameter. 9051: Side Effects: 9052: The following global variables can be set: 9053: ssi_error - If an unrecoverable error occurred this becomes true. 9054: It is up to the caller to initialize this to false 9055: if desired. 9056: ssi_error_resource - If an unrecoverable error occurred, this is the value 9057: of the resource that could not be rendered by the ssi 9058: call. 9059: ssi_error_message - The error string fetched from the ssi response 9060: in the event of an error. 9061: 9062: 9063: =head1 HANDLER SUBROUTINE 9064: 9065: ssi_with_retries() 9066: 9067: =head1 SUBROUTINES 9068: 9069: =over 9070: 9071: =item scantron_get_correction() : 9072: 9073: Builds the interface screen to interact with the operator to fix a 9074: specific error condition in a specific scanline 9075: 9076: Arguments: 9077: $r - Apache request object 9078: $i - number of the current scanline 9079: $scan_record - hash ref as returned from &scantron_parse_scanline() 9080: $scan_config - hash ref as returned from &get_scantron_config() 9081: $line - full contents of the current scanline 9082: $error - error condition, valid values are 9083: 'incorrectCODE', 'duplicateCODE', 9084: 'doublebubble', 'missingbubble', 9085: 'duplicateID', 'incorrectID' 9086: $arg - extra information needed 9087: For errors: 9088: - duplicateID - paper number that this studentID was seen before on 9089: - duplicateCODE - array ref of the paper numbers this CODE was 9090: seen on before 9091: - incorrectCODE - current incorrect CODE 9092: - doublebubble - array ref of the bubble lines that have double 9093: bubble errors 9094: - missingbubble - array ref of the bubble lines that have missing 9095: bubble errors 9096: 9097: =item scantron_get_maxbubble() : 9098: 9099: Returns the maximum number of bubble lines that are expected to 9100: occur.
