1 Revision history for Perl extension Net::Z3950::SimpleServer
3 1.20 Thu Jan 29 07:53:46 UTC 2015
4 - Add support for Type-1's proximity operator. Patch from
5 Simon Jacob of the National Library of Australia.
7 1.19 Fri Nov 22 12:31:24 CET 2013
8 - ESTIMATED_HIT_COUNT = 1 from search_handler signal.
9 - fetch handler: partial present response for undef RECORD
10 The old behavior was to return empty record (if RECORD was
11 not modified by handler). RECORD is now undefined upon entry
12 to fetch handler and handler must set it to return a record
13 or just leave it undefined to signal "no record".
15 1.18 Mon Oct 14 11:23:17 CEST 2013
16 - Debian/RPM packages now built with YAZ 5.
18 1.17 Tue Feb 12 13:30:52 CET 2013
19 - Scan and Search handler gets EXTRA_ARGS . It's represented as
20 a hash. It holds the extra arguments for SRU (URL).
21 - Scan and Search handler may return extra response data in
22 EXTRA_RESPONSE_DATA. That's an XML fragment for SRU extra
24 - Scan Term may include a DISPLAY_TERM (Z39.50 / SRU display term).
25 Thanks to Simon Jacob for patch.
27 1.16 Thu Jan 10 13:22:01 CET 2013
28 - Create packages for Ubuntu quantal precise oneiric.
29 - Add support for GFS start handler (START) to allow handling
30 of GFS config file (-c).
31 - Handler search now gets PRESENT_NUMBER - a hint for how many
32 records are to be fetched following search (piggyback).
34 1.15 Fri Oct 14 14:01:18 CEST 2011
35 - Fix decoding of OUTPUTFACETS (optinal) ; crashed on some Perl
38 1.14 Thu Aug 18 08:47:13 UTC 2011
39 - Support for facets in search handler
40 - Corrections to manual, kindly supplied by Ben Webb
41 <bjwebb67@googlemail.com>
42 - Resolve contradictory licence terms: SimpleServer is now
43 definitely distrbuted under the Revised BSD licence, whereas
44 earlier versions claimed in the source code to be Revised
45 BSD but in the README to be under the same terms as Perl.
47 1.13 Wed Mar 16 17:07:10 GMT 2011
48 - The SimpleServer test-script now uses a Unix-domain socket,
49 with a filename generated from the process-ID, rather than
50 the default Inet-document socket on port 9999. Hopefully
51 this should resolve the race-condition problems that have
52 been affecting the "make test" part of the build cycle when
53 building packages for four systems simultaneously under
56 1.12 Thu Feb 4 16:33:19 GMT 2010
57 - Remove handling of "hits" parameter in the present handler.
58 That should never have been there (and was probably sloppy
59 copy), and prevents compilation under YAZ 4, which has
60 removed the member from the bend_present_rr structure.
62 1.11 Wed Mar 4 15:12:53 GMT 2009
63 - Add explicit statement of license (same terms as Perl).
64 No functional changes.
66 1.10 Tue Mar 3 22:47:16 GMT 2009
67 - Document the init-handler's PEER_NAME argument.
68 - Update URL into YAZ documentation.
69 - bend_delete() no longer returns without value.
70 - Route around ActivePerl's damage to the "open" symbol.
72 1.09 Mon Sep 10 15:54:38 BST 2007
73 - *Argh* Another mixed statement/declaration.
75 1.08 Mon Sep 10 12:15:29 BST 2007
76 - *Sigh* Fix mixed statement/declaration.
78 1.07 Sat Sep 1 10:31:26 BST 2007
79 - When the scan-handler callback returns, do not attempt to
80 copy the terms from Perl structures if the error-code is
81 non-zero (i.e. if an error has occurred). This protects
82 against a segmentation fault when the Perl callback does not
83 explicitly set $args->{NUMBER} = 0 on error.
84 - Correct transcription of string-valued attributes in
86 - Scan handler is now passed RPN as well as TERM, a tree of
87 Perl structures representing the entire scan clause
88 including access-points and other attributes (which are
90 - The various classes used to represent nodes in the RPN query
91 tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
92 Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
93 Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
94 share a newly introduced superclass Net::Z3950::RPN::Node,
95 making it possible to write methods that apply to all node
97 - A utility method toPQF() is provided for
98 Net::Z3950::RPN::Node, enabling the RPN tree to be converted
99 back into a flat PQF query.
100 - Add support for the Delete Result Set service.
101 - Add documentation for the Sort service.
102 - Some clarifications to documentation.
104 1.06 Fri Aug 10 23:30:00 BST 2007
105 - New global-handle element can be specified when creating a
106 simple-server object and will be passed to all callback
107 functions. This allows global state to be eliminated from
108 SimpleServer applications ... finally!
109 - Search handler now deals correctly with undefined addinfo:
110 previously a (harmless) error message was emitted.
111 - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
112 applications will need if they access SRU/SRW back-end
113 databases and need to report errors.
114 - Add Perl API to yaz_diag_bib1_to_srw(), because it would
115 seem churlish not to.
117 1.05 Wed Dec 27 13:19:13 CET 2006
118 - Taking new naming convention for YAZ constants into account.
120 1.04 Fri Dec 1 10:48:32 CET 2006
121 - Build such that SimpleServer links to new yaz shared object.
123 1.03 Tue Aug 8 17:27:16 BST 2006
124 - Rely on version 2.1.14 or later of YAZ; this is the first
125 version that reliably passes through the additional
126 information associated with errors generated while serving
127 SRU/W requests. No functional differences since 1.02.
129 1.02 Wed Jul 26 12:09:50 BST 2006
130 - Better support for Open and User/Password authentication.
131 - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's
132 yaz_rpnquery_to_wrbuf() used instead. This is more robust
133 in dealing with unusual cases such as string-valued
135 - Support for SCHEMA element when fetching records.
137 1.01 Fri Mar 24 12:09:32 GMT 2006
138 - Documentation of release 1.00's SRU/SRW facilities.
139 - Makefile.PL now fails if YAZ version is earlier than 2.0.0,
140 which was the first with SRU/SRW support.
142 1.00 Fri Mar 24 01:20:24 GMT 2006
143 - Support for SRU and SRW. Mostly this is provided by the YAZ
144 GFS, but changes are needed to allow for the case where
145 there is no RPN query (due to absent on invalid <cql2rpn>
146 element in GFS configuration) so that CQL is passed through
147 natively; and also to fake up an {REQ_FORM} and {REP_FORM}
148 parameters set to the "text/xml" OID when this information
149 is not specified by the GFS.
150 (The jump in version number is due to the SRU/W support.)
151 - Include "logging-server.pl" in the distribution: the
152 simplest possible SimpleServer application, which merely
153 logs the client-request data structures.
154 - Makefile.PL is more helpful if yaz-config isn't found.
155 - Explicitly disable prototypes in SimpleServer.xs: makes no
156 difference but suppresses an error message for a cleaner
159 0.08 Mon Jun 14 14:51:01 2004
160 - SimpleServer is now perl 5.8 thread proof
161 - Support for IMP_ID parameter in Init responses. This was
162 actually written a long time ago, but left commented out as
163 the underlying YAZ back-end server didn't support
164 implementation-ID setting. Now that it does (and has done
165 for eighteen months -- since YAZ release 1.8.6 of
166 2002/03/25!), I've finally removed the comments.
167 - Init handler now understands the setting of {ERR_CODE} as
168 more than a boolean success indicator, and also {ERR_STR}.
169 They are now passed back to the client (thanks to recent
170 changes to the YAZ generic front-end server) in accordance
171 with Z39.50 Implementor Agreement 5, found at
172 http://lcweb.loc.gov/z3950/agency/agree/initdiag.html
174 0.07 Fri Jan 03 10:12:15 2003
175 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch.
176 Thanks Dave, and sorry it didn't find its way to release 0.06,
179 0.06 Thu Jan 02 11:15:01 2003
180 - Added support for authentication
181 - Add documentation for the object tree passed as the RPN
182 member of the search-handler's argument hash.
183 - We actually removed the vacuous Changelog and TODO files
184 back in 0.05. They should never have been here :-)
186 0.05 Tue Feb 05 21:54:30 2002
187 - Add brief documentation of the new handling
190 0.04 Tue Feb 05 21:49:56 2002
191 - Add Changelog (Why? We already have this file!)
192 - Add TODO file (although it's empty!)
193 - Change interface to constructor, and fix test.pl script to
194 use the new interface.
195 - Add support for Scan.
196 - Add support for building GRS-1 records.
197 - Add grs_test.pl test suite for new GRS-1 code.
198 - Add RPN structure to search-handler argument hash.
199 - Add PID element to init, search, fetch and present-handler
200 argument hashes (but not the sort, scan and close-handlers,
202 - Fix typos in documentation.
204 0.03 Thu Nov 09 16:22:00 2000
205 - Add the INSTALL file.
206 - Add support for a present-handler (distinct from fetch).
207 - Remove `$args->{LEN} = length($record)' from the example
208 fetch-handler in the documentation.
209 - Minor corrections to documentation, e.g. add commas after
210 elements in anonymous hash of arguments.
211 - Record syntaxes (formats) are now specified as ASCII OIDs
212 (e.g. "1.2.840.10003.5.10") rather than human-readable
213 strings (e.g. "usmarc")
214 - Add some XS code to support sorting, though it doesn't seem
215 to be finished yet, and is not wired out.
216 - Use symbolic constants (e.g. Z_ElementSetNames_generic
217 instead of hard-wired magic number 1).
218 - Add PEER_NAME element to init-handler argument hash.
219 - Minor changes to ztest.pl.
221 0.02 Mon Sep 11 12:32:00 2000
222 - First released versions
224 0.01 Wed Aug 30 14:54:01 2000
225 - original version; created by h2xs 1.19
228 - When invoking Init callback, set initial values of IMP_ID,
229 IMP_NAME and IMP_VER from the client's Init request.
