3 Revision history for Perl extension Net::Z3950::SimpleServer
6 - Document the init-handler's PEER_NAME argument.
7 - Update URL into YAZ documentation.
8 - bend_delete() no longer returns without value.
9 - ### When invoking Init callback, set initial values of
10 IMP_ID, IMP_NAME and IMP_VER from the client's Init request.
12 1.09 Mon Sep 10 15:54:38 BST 2007
13 - *Argh* Another mixed statement/declaration.
15 1.08 Mon Sep 10 12:15:29 BST 2007
16 - *Sigh* Fix mixed statement/declaration.
18 1.07 Sat Sep 1 10:31:26 BST 2007
19 - When the scan-handler callback returns, do not attempt to
20 copy the terms from Perl structures if the error-code is
21 non-zero (i.e. if an error has occurred). This protects
22 against a segmentation fault when the Perl callback does not
23 explicitly set $args->{NUMBER} = 0 on error.
24 - Correct transcription of string-valued attributes in
26 - Scan handler is now passed RPN as well as TERM, a tree of
27 Perl structures representing the entire scan clause
28 including access-points and other attributes (which are
30 - The various classes used to represent nodes in the RPN query
31 tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
32 Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
33 Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
34 share a newly introduced superclass Net::Z3950::RPN::Node,
35 making it possible to write methods that apply to all node
37 - A utility method toPQF() is provided for
38 Net::Z3950::RPN::Node, enabling the RPN tree to be converted
39 back into a flat PQF query.
40 - Add support for the Delete Result Set service.
41 - Add documentation for the Sort service.
42 - Some clarifications to documentation.
44 1.06 Fri Aug 10 23:30:00 BST 2007
45 - New global-handle element can be specified when creating a
46 simple-server object and will be passed to all callback
47 functions. This allows global state to be eliminated from
48 SimpleServer applications ... finally!
49 - Search handler now deals correctly with undefined addinfo:
50 previously a (harmless) error message was emitted.
51 - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
52 applications will need if they access SRU/SRW back-end
53 databases and need to report errors.
54 - Add Perl API to yaz_diag_bib1_to_srw(), because it would
57 1.05 Wed Dec 27 13:19:13 CET 2006
58 - Taking new naming convention for YAZ constants into account.
60 1.04 Fri Dec 1 10:48:32 CET 2006
61 - Build such that SimpleServer links to new yaz shared object.
63 1.03 Tue Aug 8 17:27:16 BST 2006
64 - Rely on version 2.1.14 or later of YAZ; this is the first
65 version that reliably passes through the additional
66 information associated with errors generated while serving
67 SRU/W requests. No functional differences since 1.02.
69 1.02 Wed Jul 26 12:09:50 BST 2006
70 - Better support for Open and User/Password authentication.
71 - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's
72 yaz_rpnquery_to_wrbuf() used instead. This is more robust
73 in dealing with unusual cases such as string-valued
75 - Support for SCHEMA element when fetching records.
77 1.01 Fri Mar 24 12:09:32 GMT 2006
78 - Documentation of release 1.00's SRU/SRW facilities.
79 - Makefile.PL now fails if YAZ version is earlier than 2.0.0,
80 which was the first with SRU/SRW support.
82 1.00 Fri Mar 24 01:20:24 GMT 2006
83 - Support for SRU and SRW. Mostly this is provided by the YAZ
84 GFS, but changes are needed to allow for the case where
85 there is no RPN query (due to absent on invalid <cql2rpn>
86 element in GFS configuration) so that CQL is passed through
87 natively; and also to fake up an {REQ_FORM} and {REP_FORM}
88 parameters set to the "text/xml" OID when this information
89 is not specified by the GFS.
90 (The jump in version number is due to the SRU/W support.)
91 - Include "logging-server.pl" in the distribution: the
92 simplest possible SimpleServer application, which merely
93 logs the client-request data structures.
94 - Makefile.PL is more helpful if yaz-config isn't found.
95 - Explicitly disable prototypes in SimpleServer.xs: makes no
96 difference but suppresses an error message for a cleaner
99 0.08 Mon Jun 14 14:51:01 2004
100 - SimpleServer is now perl 5.8 thread proof
101 - Support for IMP_ID parameter in Init responses. This was
102 actually written a long time ago, but left commented out as
103 the underlying YAZ back-end server didn't support
104 implementation-ID setting. Now that it does (and has done
105 for eighteen months -- since YAZ release 1.8.6 of
106 2002/03/25!), I've finally removed the comments.
107 - Init handler now understands the setting of {ERR_CODE} as
108 more than a boolean success indicator, and also {ERR_STR}.
109 They are now passed back to the client (thanks to recent
110 changes to the YAZ generic front-end server) in accordance
111 with Z39.50 Implementor Agreement 5, found at
112 http://lcweb.loc.gov/z3950/agency/agree/initdiag.html
114 0.07 Fri Jan 03 10:12:15 2003
115 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch.
116 Thanks Dave, and sorry it didn't find its way to release 0.06,
119 0.06 Thu Jan 02 11:15:01 2003
120 - Added support for authentication
121 - Add documentation for the object tree passed as the RPN
122 member of the search-handler's argument hash.
123 - We actually removed the vacuous Changelog and TODO files
124 back in 0.05. They should never have been here :-)
126 0.05 Tue Feb 05 21:54:30 2002
127 - Add brief documentation of the new handling
130 0.04 Tue Feb 05 21:49:56 2002
131 - Add Changelog (Why? We already have this file!)
132 - Add TODO file (although it's empty!)
133 - Change interface to constructor, and fix test.pl script to
134 use the new interface.
135 - Add support for Scan.
136 - Add support for building GRS-1 records.
137 - Add grs_test.pl test suite for new GRS-1 code.
138 - Add RPN structure to search-handler argument hash.
139 - Add PID element to init, search, fetch and present-handler
140 argument hashes (but not the sort, scan and close-handlers,
142 - Fix typos in documentation.
144 0.03 Thu Nov 09 16:22:00 2000
145 - Add the INSTALL file.
146 - Add support for a present-handler (distinct from fetch).
147 - Remove `$args->{LEN} = length($record)' from the example
148 fetch-handler in the documentation.
149 - Minor corrections to documentation, e.g. add commas after
150 elements in anonymous hash of arguments.
151 - Record syntaxes (formats) are now specified as ASCII OIDs
152 (e.g. "1.2.840.10003.5.10") rather than human-readable
153 strings (e.g. "usmarc")
154 - Add some XS code to support sorting, though it doesn't seem
155 to be finished yet, and is not wired out.
156 - Use symbolic constants (e.g. Z_ElementSetNames_generic
157 instead of hard-wired magic number 1).
158 - Add PEER_NAME element to init-handler argument hash.
159 - Minor changes to ztest.pl.

162 - First released versions
164 0.01 Wed Aug 30 14:54:01 2000
