Revision history for Perl extension Net::Z3950::SimpleServer 1.20 Thu Jan 29 07:53:46 UTC 2015 - Add support for Type-1's proximity operator. Patch from Simon Jacob of the National Library of Australia. 1.19 Fri Nov 22 12:31:24 CET 2013 - ESTIMATED_HIT_COUNT = 1 from search_handler signal. - fetch handler: partial present response for undef RECORD The old behavior was to return empty record (if RECORD was not modified by handler). RECORD is now undefined upon entry to fetch handler and handler must set it to return a record or just leave it undefined to signal "no record". 1.18 Mon Oct 14 11:23:17 CEST 2013 - Debian/RPM packages now built with YAZ 5. 1.17 Tue Feb 12 13:30:52 CET 2013 - Scan and Search handler gets EXTRA_ARGS . It's represented as a hash. It holds the extra arguments for SRU (URL). - Scan and Search handler may return extra response data in EXTRA_RESPONSE_DATA. That's an XML fragment for SRU extra response data. - Scan Term may include a DISPLAY_TERM (Z39.50 / SRU display term). Thanks to Simon Jacob for patch. 1.16 Thu Jan 10 13:22:01 CET 2013 - Create packages for Ubuntu quantal precise oneiric. - Add support for GFS start handler (START) to allow handling of GFS config file (-c). - Handler search now gets PRESENT_NUMBER - a hint for how many records are to be fetched following search (piggyback). 1.15 Fri Oct 14 14:01:18 CEST 2011 - Fix decoding of OUTPUTFACETS (optinal) ; crashed on some Perl versions 1.14 Thu Aug 18 08:47:13 UTC 2011 - Support for facets in search handler - Corrections to manual, kindly supplied by Ben Webb - Resolve contradictory licence terms: SimpleServer is now definitely distrbuted under the Revised BSD licence, whereas earlier versions claimed in the source code to be Revised BSD but in the README to be under the same terms as Perl. 1.13 Wed Mar 16 17:07:10 GMT 2011 - The SimpleServer test-script now uses a Unix-domain socket, with a filename generated from the process-ID, rather than the default Inet-document socket on port 9999. Hopefully this should resolve the race-condition problems that have been affecting the "make test" part of the build cycle when building packages for four systems simultaneously under id-pbuild.sh 1.12 Thu Feb 4 16:33:19 GMT 2010 - Remove handling of "hits" parameter in the present handler. That should never have been there (and was probably sloppy copy), and prevents compilation under YAZ 4, which has removed the member from the bend_present_rr structure. 1.11 Wed Mar 4 15:12:53 GMT 2009 - Add explicit statement of license (same terms as Perl). No functional changes. 1.10 Tue Mar 3 22:47:16 GMT 2009 - Document the init-handler's PEER_NAME argument. - Update URL into YAZ documentation. - bend_delete() no longer returns without value. - Route around ActivePerl's damage to the "open" symbol. 1.09 Mon Sep 10 15:54:38 BST 2007 - *Argh* Another mixed statement/declaration. 1.08 Mon Sep 10 12:15:29 BST 2007 - *Sigh* Fix mixed statement/declaration. 1.07 Sat Sep 1 10:31:26 BST 2007 - 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. - 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. - Add documentation for the Sort service. - Some clarifications to documentation. 1.06 Fri Aug 10 23:30:00 BST 2007 - 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 SimpleServer applications ... finally! - Search handler now deals correctly with undefined addinfo: previously a (harmless) error message was emitted. - 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. 1.05 Wed Dec 27 13:19:13 CET 2006 - Taking new naming convention for YAZ constants into account. 1.04 Fri Dec 1 10:48:32 CET 2006 - Build such that SimpleServer links to new yaz shared object. 1.03 Tue Aug 8 17:27:16 BST 2006 - Rely on version 2.1.14 or later of YAZ; this is the first version that reliably passes through the additional information associated with errors generated while serving SRU/W requests. No functional differences since 1.02. 1.02 Wed Jul 26 12:09:50 BST 2006 - Better support for Open and User/Password authentication. - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's yaz_rpnquery_to_wrbuf() used instead. This is more robust in dealing with unusual cases such as string-valued attributes. - Support for SCHEMA element when fetching records. 1.01 Fri Mar 24 12:09:32 GMT 2006 - Documentation of release 1.00's SRU/SRW facilities. - Makefile.PL now fails if YAZ version is earlier than 2.0.0, which was the first with SRU/SRW support. 1.00 Fri Mar 24 01:20:24 GMT 2006 - Support for SRU and SRW. Mostly this is provided by the YAZ GFS, but changes are needed to allow for the case where there is no RPN query (due to absent on invalid element in GFS configuration) so that CQL is passed through natively; and also to fake up an {REQ_FORM} and {REP_FORM} parameters set to the "text/xml" OID when this information is not specified by the GFS. (The jump in version number is due to the SRU/W support.) - Include "logging-server.pl" in the distribution: the simplest possible SimpleServer application, which merely logs the client-request data structures. - Makefile.PL is more helpful if yaz-config isn't found. - Explicitly disable prototypes in SimpleServer.xs: makes no difference but suppresses an error message for a cleaner build. 0.08 Mon Jun 14 14:51:01 2004 - SimpleServer is now perl 5.8 thread proof - Support for IMP_ID parameter in Init responses. This was actually written a long time ago, but left commented out as the underlying YAZ back-end server didn't support implementation-ID setting. Now that it does (and has done for eighteen months -- since YAZ release 1.8.6 of 2002/03/25!), I've finally removed the comments. - Init handler now understands the setting of {ERR_CODE} as more than a boolean success indicator, and also {ERR_STR}. They are now passed back to the client (thanks to recent changes to the YAZ generic front-end server) in accordance with Z39.50 Implementor Agreement 5, found at http://lcweb.loc.gov/z3950/agency/agree/initdiag.html 0.07 Fri Jan 03 10:12:15 2003 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch. Thanks Dave, and sorry it didn't find its way to release 0.06, completely my fault. 0.06 Thu Jan 02 11:15:01 2003 - Added support for authentication - Add documentation for the object tree passed as the RPN member of the search-handler's argument hash. - We actually removed the vacuous Changelog and TODO files back in 0.05. They should never have been here :-) 0.05 Tue Feb 05 21:54:30 2002 - Add brief documentation of the new handling of RPN. 0.04 Tue Feb 05 21:49:56 2002 - Add Changelog (Why? We already have this file!) - Add TODO file (although it's empty!) - Change interface to constructor, and fix test.pl script to use the new interface. - Add support for Scan. - Add support for building GRS-1 records. - Add grs_test.pl test suite for new GRS-1 code. - Add RPN structure to search-handler argument hash. - Add PID element to init, search, fetch and present-handler argument hashes (but not the sort, scan and close-handlers, for some reason.) - Fix typos in documentation. 0.03 Thu Nov 09 16:22:00 2000 - Add the INSTALL file. - Add support for a present-handler (distinct from fetch). - Remove `$args->{LEN} = length($record)' from the example fetch-handler in the documentation. - Minor corrections to documentation, e.g. add commas after elements in anonymous hash of arguments. - Record syntaxes (formats) are now specified as ASCII OIDs (e.g. "1.2.840.10003.5.10") rather than human-readable strings (e.g. "usmarc") - Add some XS code to support sorting, though it doesn't seem to be finished yet, and is not wired out. - Use symbolic constants (e.g. Z_ElementSetNames_generic instead of hard-wired magic number 1). - Add PEER_NAME element to init-handler argument hash. - Minor changes to ztest.pl. 0.02 Mon Sep 11 12:32:00 2000 - First released versions 0.01 Wed Aug 30 14:54:01 2000 - original version; created by h2xs 1.19 ### To do - When invoking Init callback, set initial values of IMP_ID, IMP_NAME and IMP_VER from the client's Init request.
