Revision history for Perl extension Net::Z3950::SimpleServer
-1.06 (IN PROGRESS)
+1.07 (IN PROGRESS)
+ - When the scan-handler callback returns, do not attempt to
+ copy the terms from Perl structures if the error-code is
+ non-zero (i.e. if an error has occurred). This protects
+ against a segmentation fault when the Perl callback does not
+ explicitly set $args->{NUMBER} = 0 on error.
+ - Some clarifications to documentation.
+ - Correct transcription of string-valued attributes in
+ $args->{RPN}.
+ - Scan handler is now passed RPN as well as TERM, a tree of
+ Perl structures representing the entire scan clause
+ including access-points and other attributes (which are
+ discarded from TERM).
+ - The various classes used to represent nodes in the RPN query
+ tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
+ Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
+ Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
+ share a newly introduced superclass Net::Z3950::RPN::Node,
+ making it possible to write methods that apply to all node
+ types.
+ - A utility method toPQF() is provided for
+ Net::Z3950::RPN::Node, enabling the RPN tree to be converted
+ back into a flat PQF query.
+ - Add support for the Delete Result Set service.

- New global-handle element can be specified when creating a
simple-server object and will be passed to all callback
functions. This allows global state to be eliminated from
- Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
applications will need if they access SRU/SRW back-end
databases and need to report errors.
+ - Add Perl API to yaz_diag_bib1_to_srw(), because it would
+ seem churlish not to.

- Taking new naming convention for YAZ constants into account.
