1 Revision history for Perl extension Net::Z3950::SimpleServer
3 1.14 Thu Aug 18 08:47:13 UTC 2011
4 - Support for facets in search handler
5 - Corrections to manual, kindly supplied by Ben Webb
6 <bjwebb67@googlemail.com>
7 - Resolve contradictory licence terms: SimpleServer is now
8 definitely distrbuted under the Revised BSD licence, whereas
9 earlier versions claimed in the source code to be Revised
10 BSD but in the README to be under the same terms as Perl.
12 1.13 Wed Mar 16 17:07:10 GMT 2011
13 - The SimpleServer test-script now uses a Unix-domain socket,
14 with a filename generated from the process-ID, rather than
15 the default Inet-document socket on port 9999. Hopefully
16 this should resolve the race-condition problems that have
17 been affecting the "make test" part of the build cycle when
18 building packages for four systems simultaneously under
21 1.12 Thu Feb 4 16:33:19 GMT 2010
22 - Remove handling of "hits" parameter in the present handler.
23 That should never have been there (and was probably sloppy
24 copy), and prevents compilation under YAZ 4, which has
25 removed the member from the bend_present_rr structure.
27 1.11 Wed Mar 4 15:12:53 GMT 2009
28 - Add explicit statement of license (same terms as Perl).
29 No functional changes.
31 1.10 Tue Mar 3 22:47:16 GMT 2009
32 - Document the init-handler's PEER_NAME argument.
33 - Update URL into YAZ documentation.
34 - bend_delete() no longer returns without value.
35 - Route around ActivePerl's damage to the "open" symbol.
37 1.09 Mon Sep 10 15:54:38 BST 2007
38 - *Argh* Another mixed statement/declaration.
40 1.08 Mon Sep 10 12:15:29 BST 2007
41 - *Sigh* Fix mixed statement/declaration.
43 1.07 Sat Sep 1 10:31:26 BST 2007
44 - When the scan-handler callback returns, do not attempt to
45 copy the terms from Perl structures if the error-code is
46 non-zero (i.e. if an error has occurred). This protects
47 against a segmentation fault when the Perl callback does not
48 explicitly set $args->{NUMBER} = 0 on error.
49 - Correct transcription of string-valued attributes in
51 - Scan handler is now passed RPN as well as TERM, a tree of
52 Perl structures representing the entire scan clause
53 including access-points and other attributes (which are
55 - The various classes used to represent nodes in the RPN query
56 tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
57 Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
58 Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
59 share a newly introduced superclass Net::Z3950::RPN::Node,
60 making it possible to write methods that apply to all node
62 - A utility method toPQF() is provided for
63 Net::Z3950::RPN::Node, enabling the RPN tree to be converted
64 back into a flat PQF query.
65 - Add support for the Delete Result Set service.
66 - Add documentation for the Sort service.
67 - Some clarifications to documentation.
69 1.06 Fri Aug 10 23:30:00 BST 2007
70 - New global-handle element can be specified when creating a
71 simple-server object and will be passed to all callback
72 functions. This allows global state to be eliminated from
73 SimpleServer applications ... finally!
74 - Search handler now deals correctly with undefined addinfo:
75 previously a (harmless) error message was emitted.
76 - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
77 applications will need if they access SRU/SRW back-end
78 databases and need to report errors.
79 - Add Perl API to yaz_diag_bib1_to_srw(), because it would
82 1.05 Wed Dec 27 13:19:13 CET 2006
83 - Taking new naming convention for YAZ constants into account.
85 1.04 Fri Dec 1 10:48:32 CET 2006
86 - Build such that SimpleServer links to new yaz shared object.
88 1.03 Tue Aug 8 17:27:16 BST 2006
89 - Rely on version 2.1.14 or later of YAZ; this is the first
90 version that reliably passes through the additional
91 information associated with errors generated while serving
92 SRU/W requests. No functional differences since 1.02.
94 1.02 Wed Jul 26 12:09:50 BST 2006
95 - Better support for Open and User/Password authentication.
96 - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's
97 yaz_rpnquery_to_wrbuf() used instead. This is more robust
98 in dealing with unusual cases such as string-valued
100 - Support for SCHEMA element when fetching records.
102 1.01 Fri Mar 24 12:09:32 GMT 2006
103 - Documentation of release 1.00's SRU/SRW facilities.
104 - Makefile.PL now fails if YAZ version is earlier than 2.0.0,
105 which was the first with SRU/SRW support.
107 1.00 Fri Mar 24 01:20:24 GMT 2006
108 - Support for SRU and SRW. Mostly this is provided by the YAZ
109 GFS, but changes are needed to allow for the case where
110 there is no RPN query (due to absent on invalid <cql2rpn>
111 element in GFS configuration) so that CQL is passed through
112 natively; and also to fake up an {REQ_FORM} and {REP_FORM}
113 parameters set to the "text/xml" OID when this information
114 is not specified by the GFS.
115 (The jump in version number is due to the SRU/W support.)
116 - Include "logging-server.pl" in the distribution: the
117 simplest possible SimpleServer application, which merely
118 logs the client-request data structures.
119 - Makefile.PL is more helpful if yaz-config isn't found.
120 - Explicitly disable prototypes in SimpleServer.xs: makes no
121 difference but suppresses an error message for a cleaner
124 0.08 Mon Jun 14 14:51:01 2004
125 - SimpleServer is now perl 5.8 thread proof
126 - Support for IMP_ID parameter in Init responses. This was
127 actually written a long time ago, but left commented out as
128 the underlying YAZ back-end server didn't support
129 implementation-ID setting. Now that it does (and has done
130 for eighteen months -- since YAZ release 1.8.6 of
131 2002/03/25!), I've finally removed the comments.
132 - Init handler now understands the setting of {ERR_CODE} as
133 more than a boolean success indicator, and also {ERR_STR}.
134 They are now passed back to the client (thanks to recent
135 changes to the YAZ generic front-end server) in accordance
136 with Z39.50 Implementor Agreement 5, found at
137 http://lcweb.loc.gov/z3950/agency/agree/initdiag.html
139 0.07 Fri Jan 03 10:12:15 2003
140 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch.
141 Thanks Dave, and sorry it didn't find its way to release 0.06,
144 0.06 Thu Jan 02 11:15:01 2003
145 - Added support for authentication
146 - Add documentation for the object tree passed as the RPN
147 member of the search-handler's argument hash.
148 - We actually removed the vacuous Changelog and TODO files
149 back in 0.05. They should never have been here :-)
151 0.05 Tue Feb 05 21:54:30 2002
152 - Add brief documentation of the new handling
155 0.04 Tue Feb 05 21:49:56 2002
156 - Add Changelog (Why? We already have this file!)
157 - Add TODO file (although it's empty!)
158 - Change interface to constructor, and fix test.pl script to
159 use the new interface.
160 - Add support for Scan.
161 - Add support for building GRS-1 records.
162 - Add grs_test.pl test suite for new GRS-1 code.
163 - Add RPN structure to search-handler argument hash.
164 - Add PID element to init, search, fetch and present-handler
165 argument hashes (but not the sort, scan and close-handlers,
167 - Fix typos in documentation.
169 0.03 Thu Nov 09 16:22:00 2000
170 - Add the INSTALL file.
171 - Add support for a present-handler (distinct from fetch).
172 - Remove `$args->{LEN} = length($record)' from the example
173 fetch-handler in the documentation.
174 - Minor corrections to documentation, e.g. add commas after
175 elements in anonymous hash of arguments.
176 - Record syntaxes (formats) are now specified as ASCII OIDs
177 (e.g. "1.2.840.10003.5.10") rather than human-readable
178 strings (e.g. "usmarc")
179 - Add some XS code to support sorting, though it doesn't seem
180 to be finished yet, and is not wired out.
181 - Use symbolic constants (e.g. Z_ElementSetNames_generic
182 instead of hard-wired magic number 1).
183 - Add PEER_NAME element to init-handler argument hash.
184 - Minor changes to ztest.pl.
186 0.02 Mon Sep 11 12:32:00 2000
187 - First released versions
189 0.01 Wed Aug 30 14:54:01 2000
190 - original version; created by h2xs 1.19
193 - When invoking Init callback, set initial values of IMP_ID,
194 IMP_NAME and IMP_VER from the client's Init request.
