3 Revision history for Perl extension Net::Z3950::SimpleServer
5 1.11 Wed Mar 4 15:12:53 GMT 2009
6 - Add explicit statement of license (same terms as Perl).
9 1.10 Tue Mar 3 22:47:16 GMT 2009
10 - Document the init-handler's PEER_NAME argument.
11 - Update URL into YAZ documentation.
12 - bend_delete() no longer returns without value.
13 - Route around ActivePerl's damage to the "open" symbol.
15 1.09 Mon Sep 10 15:54:38 BST 2007
16 - *Argh* Another mixed statement/declaration.
18 1.08 Mon Sep 10 12:15:29 BST 2007
19 - *Sigh* Fix mixed statement/declaration.
21 1.07 Sat Sep 1 10:31:26 BST 2007
22 - When the scan-handler callback returns, do not attempt to
23 copy the terms from Perl structures if the error-code is
24 non-zero (i.e. if an error has occurred). This protects
25 against a segmentation fault when the Perl callback does not
26 explicitly set $args->{NUMBER} = 0 on error.
27 - Correct transcription of string-valued attributes in
29 - Scan handler is now passed RPN as well as TERM, a tree of
30 Perl structures representing the entire scan clause
31 including access-points and other attributes (which are
33 - The various classes used to represent nodes in the RPN query
34 tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
35 Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
36 Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
37 share a newly introduced superclass Net::Z3950::RPN::Node,
38 making it possible to write methods that apply to all node
40 - A utility method toPQF() is provided for
41 Net::Z3950::RPN::Node, enabling the RPN tree to be converted
42 back into a flat PQF query.
43 - Add support for the Delete Result Set service.
44 - Add documentation for the Sort service.
45 - Some clarifications to documentation.
47 1.06 Fri Aug 10 23:30:00 BST 2007
48 - New global-handle element can be specified when creating a
49 simple-server object and will be passed to all callback
50 functions. This allows global state to be eliminated from
51 SimpleServer applications ... finally!
52 - Search handler now deals correctly with undefined addinfo:
53 previously a (harmless) error message was emitted.
54 - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
55 applications will need if they access SRU/SRW back-end
56 databases and need to report errors.
57 - Add Perl API to yaz_diag_bib1_to_srw(), because it would
60 1.05 Wed Dec 27 13:19:13 CET 2006
61 - Taking new naming convention for YAZ constants into account.
63 1.04 Fri Dec 1 10:48:32 CET 2006
64 - Build such that SimpleServer links to new yaz shared object.
66 1.03 Tue Aug 8 17:27:16 BST 2006
67 - Rely on version 2.1.14 or later of YAZ; this is the first
68 version that reliably passes through the additional
69 information associated with errors generated while serving
70 SRU/W requests. No functional differences since 1.02.
72 1.02 Wed Jul 26 12:09:50 BST 2006
73 - Better support for Open and User/Password authentication.
74 - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's
75 yaz_rpnquery_to_wrbuf() used instead. This is more robust
76 in dealing with unusual cases such as string-valued
78 - Support for SCHEMA element when fetching records.
80 1.01 Fri Mar 24 12:09:32 GMT 2006
81 - Documentation of release 1.00's SRU/SRW facilities.
82 - Makefile.PL now fails if YAZ version is earlier than 2.0.0,
83 which was the first with SRU/SRW support.
85 1.00 Fri Mar 24 01:20:24 GMT 2006
86 - Support for SRU and SRW. Mostly this is provided by the YAZ
87 GFS, but changes are needed to allow for the case where
88 there is no RPN query (due to absent on invalid <cql2rpn>
89 element in GFS configuration) so that CQL is passed through
90 natively; and also to fake up an {REQ_FORM} and {REP_FORM}
91 parameters set to the "text/xml" OID when this information
92 is not specified by the GFS.
93 (The jump in version number is due to the SRU/W support.)
94 - Include "logging-server.pl" in the distribution: the
95 simplest possible SimpleServer application, which merely
96 logs the client-request data structures.
97 - Makefile.PL is more helpful if yaz-config isn't found.
98 - Explicitly disable prototypes in SimpleServer.xs: makes no
99 difference but suppresses an error message for a cleaner
102 0.08 Mon Jun 14 14:51:01 2004
103 - SimpleServer is now perl 5.8 thread proof
104 - Support for IMP_ID parameter in Init responses. This was
105 actually written a long time ago, but left commented out as
106 the underlying YAZ back-end server didn't support
107 implementation-ID setting. Now that it does (and has done
108 for eighteen months -- since YAZ release 1.8.6 of
109 2002/03/25!), I've finally removed the comments.
110 - Init handler now understands the setting of {ERR_CODE} as
111 more than a boolean success indicator, and also {ERR_STR}.
112 They are now passed back to the client (thanks to recent
113 changes to the YAZ generic front-end server) in accordance
114 with Z39.50 Implementor Agreement 5, found at
115 http://lcweb.loc.gov/z3950/agency/agree/initdiag.html
117 0.07 Fri Jan 03 10:12:15 2003
118 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch.
119 Thanks Dave, and sorry it didn't find its way to release 0.06,
122 0.06 Thu Jan 02 11:15:01 2003
123 - Added support for authentication
124 - Add documentation for the object tree passed as the RPN
125 member of the search-handler's argument hash.
126 - We actually removed the vacuous Changelog and TODO files
127 back in 0.05. They should never have been here :-)
129 0.05 Tue Feb 05 21:54:30 2002
130 - Add brief documentation of the new handling
133 0.04 Tue Feb 05 21:49:56 2002
134 - Add Changelog (Why? We already have this file!)
135 - Add TODO file (although it's empty!)
136 - Change interface to constructor, and fix test.pl script to
137 use the new interface.
138 - Add support for Scan.
139 - Add support for building GRS-1 records.
140 - Add grs_test.pl test suite for new GRS-1 code.
141 - Add RPN structure to search-handler argument hash.
142 - Add PID element to init, search, fetch and present-handler
143 argument hashes (but not the sort, scan and close-handlers,
145 - Fix typos in documentation.
147 0.03 Thu Nov 09 16:22:00 2000
148 - Add the INSTALL file.
149 - Add support for a present-handler (distinct from fetch).
150 - Remove `$args->{LEN} = length($record)' from the example
151 fetch-handler in the documentation.
152 - Minor corrections to documentation, e.g. add commas after
153 elements in anonymous hash of arguments.
154 - Record syntaxes (formats) are now specified as ASCII OIDs
155 (e.g. "1.2.840.10003.5.10") rather than human-readable
156 strings (e.g. "usmarc")
157 - Add some XS code to support sorting, though it doesn't seem
158 to be finished yet, and is not wired out.
159 - Use symbolic constants (e.g. Z_ElementSetNames_generic
160 instead of hard-wired magic number 1).
161 - Add PEER_NAME element to init-handler argument hash.
162 - Minor changes to ztest.pl.
164 0.02 Mon Sep 11 12:32:00 2000
165 - First released versions
167 0.01 Wed Aug 30 14:54:01 2000
168 - original version; created by h2xs 1.19
171 - When invoking Init callback, set initial values of IMP_ID,
172 IMP_NAME and IMP_VER from the client's Init request.
