3 Revision history for Perl extension Net::Z3950::SimpleServer
5 1.12 Thu Feb 4 16:33:19 GMT 2010
6 - Remove handling of "hits" parameter in the present handler.
7 That should never have been there (and was probably sloppy
8 copy), and prevents compilation under YAZ 4, which has
9 removed the member from the bend_present_rr structure.
11 1.11 Wed Mar 4 15:12:53 GMT 2009
12 - Add explicit statement of license (same terms as Perl).
13 No functional changes.
15 1.10 Tue Mar 3 22:47:16 GMT 2009
16 - Document the init-handler's PEER_NAME argument.
17 - Update URL into YAZ documentation.
18 - bend_delete() no longer returns without value.
19 - Route around ActivePerl's damage to the "open" symbol.
21 1.09 Mon Sep 10 15:54:38 BST 2007
22 - *Argh* Another mixed statement/declaration.
24 1.08 Mon Sep 10 12:15:29 BST 2007
25 - *Sigh* Fix mixed statement/declaration.
27 1.07 Sat Sep 1 10:31:26 BST 2007
28 - When the scan-handler callback returns, do not attempt to
29 copy the terms from Perl structures if the error-code is
30 non-zero (i.e. if an error has occurred). This protects
31 against a segmentation fault when the Perl callback does not
32 explicitly set $args->{NUMBER} = 0 on error.
33 - Correct transcription of string-valued attributes in
35 - Scan handler is now passed RPN as well as TERM, a tree of
36 Perl structures representing the entire scan clause
37 including access-points and other attributes (which are
39 - The various classes used to represent nodes in the RPN query
40 tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
41 Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
42 Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
43 share a newly introduced superclass Net::Z3950::RPN::Node,
44 making it possible to write methods that apply to all node
46 - A utility method toPQF() is provided for
47 Net::Z3950::RPN::Node, enabling the RPN tree to be converted
48 back into a flat PQF query.
49 - Add support for the Delete Result Set service.
50 - Add documentation for the Sort service.
51 - Some clarifications to documentation.
53 1.06 Fri Aug 10 23:30:00 BST 2007
54 - New global-handle element can be specified when creating a
55 simple-server object and will be passed to all callback
56 functions. This allows global state to be eliminated from
57 SimpleServer applications ... finally!
58 - Search handler now deals correctly with undefined addinfo:
59 previously a (harmless) error message was emitted.
60 - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
61 applications will need if they access SRU/SRW back-end
62 databases and need to report errors.
63 - Add Perl API to yaz_diag_bib1_to_srw(), because it would
66 1.05 Wed Dec 27 13:19:13 CET 2006
67 - Taking new naming convention for YAZ constants into account.
69 1.04 Fri Dec 1 10:48:32 CET 2006
70 - Build such that SimpleServer links to new yaz shared object.
72 1.03 Tue Aug 8 17:27:16 BST 2006
73 - Rely on version 2.1.14 or later of YAZ; this is the first
74 version that reliably passes through the additional
75 information associated with errors generated while serving
76 SRU/W requests. No functional differences since 1.02.
78 1.02 Wed Jul 26 12:09:50 BST 2006
79 - Better support for Open and User/Password authentication.
80 - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's
81 yaz_rpnquery_to_wrbuf() used instead. This is more robust
82 in dealing with unusual cases such as string-valued
84 - Support for SCHEMA element when fetching records.
86 1.01 Fri Mar 24 12:09:32 GMT 2006
87 - Documentation of release 1.00's SRU/SRW facilities.
88 - Makefile.PL now fails if YAZ version is earlier than 2.0.0,
89 which was the first with SRU/SRW support.
91 1.00 Fri Mar 24 01:20:24 GMT 2006
92 - Support for SRU and SRW. Mostly this is provided by the YAZ
93 GFS, but changes are needed to allow for the case where
94 there is no RPN query (due to absent on invalid <cql2rpn>
95 element in GFS configuration) so that CQL is passed through
96 natively; and also to fake up an {REQ_FORM} and {REP_FORM}
97 parameters set to the "text/xml" OID when this information
98 is not specified by the GFS.
99 (The jump in version number is due to the SRU/W support.)
100 - Include "logging-server.pl" in the distribution: the
101 simplest possible SimpleServer application, which merely
102 logs the client-request data structures.
103 - Makefile.PL is more helpful if yaz-config isn't found.
104 - Explicitly disable prototypes in SimpleServer.xs: makes no
105 difference but suppresses an error message for a cleaner
108 0.08 Mon Jun 14 14:51:01 2004
109 - SimpleServer is now perl 5.8 thread proof
110 - Support for IMP_ID parameter in Init responses. This was
111 actually written a long time ago, but left commented out as
112 the underlying YAZ back-end server didn't support
113 implementation-ID setting. Now that it does (and has done
114 for eighteen months -- since YAZ release 1.8.6 of
115 2002/03/25!), I've finally removed the comments.
116 - Init handler now understands the setting of {ERR_CODE} as
117 more than a boolean success indicator, and also {ERR_STR}.
118 They are now passed back to the client (thanks to recent
119 changes to the YAZ generic front-end server) in accordance
120 with Z39.50 Implementor Agreement 5, found at
121 http://lcweb.loc.gov/z3950/agency/agree/initdiag.html
123 0.07 Fri Jan 03 10:12:15 2003
124 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch.
125 Thanks Dave, and sorry it didn't find its way to release 0.06,
128 0.06 Thu Jan 02 11:15:01 2003
129 - Added support for authentication
130 - Add documentation for the object tree passed as the RPN
131 member of the search-handler's argument hash.
132 - We actually removed the vacuous Changelog and TODO files
133 back in 0.05. They should never have been here :-)
135 0.05 Tue Feb 05 21:54:30 2002
136 - Add brief documentation of the new handling
139 0.04 Tue Feb 05 21:49:56 2002
140 - Add Changelog (Why? We already have this file!)
141 - Add TODO file (although it's empty!)
142 - Change interface to constructor, and fix test.pl script to
143 use the new interface.
144 - Add support for Scan.
145 - Add support for building GRS-1 records.
146 - Add grs_test.pl test suite for new GRS-1 code.
147 - Add RPN structure to search-handler argument hash.
148 - Add PID element to init, search, fetch and present-handler
149 argument hashes (but not the sort, scan and close-handlers,
151 - Fix typos in documentation.
153 0.03 Thu Nov 09 16:22:00 2000
154 - Add the INSTALL file.
155 - Add support for a present-handler (distinct from fetch).
156 - Remove `$args->{LEN} = length($record)' from the example
157 fetch-handler in the documentation.
158 - Minor corrections to documentation, e.g. add commas after
159 elements in anonymous hash of arguments.
160 - Record syntaxes (formats) are now specified as ASCII OIDs
161 (e.g. "1.2.840.10003.5.10") rather than human-readable
162 strings (e.g. "usmarc")
163 - Add some XS code to support sorting, though it doesn't seem
164 to be finished yet, and is not wired out.
165 - Use symbolic constants (e.g. Z_ElementSetNames_generic
166 instead of hard-wired magic number 1).
167 - Add PEER_NAME element to init-handler argument hash.
168 - Minor changes to ztest.pl.
170 0.02 Mon Sep 11 12:32:00 2000
171 - First released versions
173 0.01 Wed Aug 30 14:54:01 2000
174 - original version; created by h2xs 1.19
177 - When invoking Init callback, set initial values of IMP_ID,
178 IMP_NAME and IMP_VER from the client's Init request.
