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 - Route around ActivePerl's damage to the "open" symbol.
11 1.09 Mon Sep 10 15:54:38 BST 2007
12 - *Argh* Another mixed statement/declaration.
14 1.08 Mon Sep 10 12:15:29 BST 2007
15 - *Sigh* Fix mixed statement/declaration.
17 1.07 Sat Sep 1 10:31:26 BST 2007
18 - When the scan-handler callback returns, do not attempt to
19 copy the terms from Perl structures if the error-code is
20 non-zero (i.e. if an error has occurred). This protects
21 against a segmentation fault when the Perl callback does not
22 explicitly set $args->{NUMBER} = 0 on error.
23 - Correct transcription of string-valued attributes in
25 - Scan handler is now passed RPN as well as TERM, a tree of
26 Perl structures representing the entire scan clause
27 including access-points and other attributes (which are
29 - The various classes used to represent nodes in the RPN query
30 tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
31 Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
32 Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
33 share a newly introduced superclass Net::Z3950::RPN::Node,
34 making it possible to write methods that apply to all node
36 - A utility method toPQF() is provided for
37 Net::Z3950::RPN::Node, enabling the RPN tree to be converted
38 back into a flat PQF query.
39 - Add support for the Delete Result Set service.
40 - Add documentation for the Sort service.
41 - Some clarifications to documentation.
43 1.06 Fri Aug 10 23:30:00 BST 2007
44 - New global-handle element can be specified when creating a
45 simple-server object and will be passed to all callback
46 functions. This allows global state to be eliminated from
47 SimpleServer applications ... finally!
48 - Search handler now deals correctly with undefined addinfo:
49 previously a (harmless) error message was emitted.
50 - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
51 applications will need if they access SRU/SRW back-end
52 databases and need to report errors.
53 - Add Perl API to yaz_diag_bib1_to_srw(), because it would
56 1.05 Wed Dec 27 13:19:13 CET 2006
57 - Taking new naming convention for YAZ constants into account.
59 1.04 Fri Dec 1 10:48:32 CET 2006
60 - Build such that SimpleServer links to new yaz shared object.
62 1.03 Tue Aug 8 17:27:16 BST 2006
63 - Rely on version 2.1.14 or later of YAZ; this is the first
64 version that reliably passes through the additional
65 information associated with errors generated while serving
66 SRU/W requests. No functional differences since 1.02.
68 1.02 Wed Jul 26 12:09:50 BST 2006
69 - Better support for Open and User/Password authentication.
70 - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's
71 yaz_rpnquery_to_wrbuf() used instead. This is more robust
72 in dealing with unusual cases such as string-valued
74 - Support for SCHEMA element when fetching records.
76 1.01 Fri Mar 24 12:09:32 GMT 2006
77 - Documentation of release 1.00's SRU/SRW facilities.
78 - Makefile.PL now fails if YAZ version is earlier than 2.0.0,
79 which was the first with SRU/SRW support.
81 1.00 Fri Mar 24 01:20:24 GMT 2006
82 - Support for SRU and SRW. Mostly this is provided by the YAZ
83 GFS, but changes are needed to allow for the case where
84 there is no RPN query (due to absent on invalid <cql2rpn>
85 element in GFS configuration) so that CQL is passed through
86 natively; and also to fake up an {REQ_FORM} and {REP_FORM}
87 parameters set to the "text/xml" OID when this information
88 is not specified by the GFS.
89 (The jump in version number is due to the SRU/W support.)
90 - Include "logging-server.pl" in the distribution: the
91 simplest possible SimpleServer application, which merely
92 logs the client-request data structures.
93 - Makefile.PL is more helpful if yaz-config isn't found.
94 - Explicitly disable prototypes in SimpleServer.xs: makes no
95 difference but suppresses an error message for a cleaner
98 0.08 Mon Jun 14 14:51:01 2004
99 - SimpleServer is now perl 5.8 thread proof
100 - Support for IMP_ID parameter in Init responses. This was
101 actually written a long time ago, but left commented out as
102 the underlying YAZ back-end server didn't support
103 implementation-ID setting. Now that it does (and has done
104 for eighteen months -- since YAZ release 1.8.6 of
105 2002/03/25!), I've finally removed the comments.
106 - Init handler now understands the setting of {ERR_CODE} as
107 more than a boolean success indicator, and also {ERR_STR}.
108 They are now passed back to the client (thanks to recent
109 changes to the YAZ generic front-end server) in accordance
110 with Z39.50 Implementor Agreement 5, found at
111 http://lcweb.loc.gov/z3950/agency/agree/initdiag.html
113 0.07 Fri Jan 03 10:12:15 2003
114 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch.
115 Thanks Dave, and sorry it didn't find its way to release 0.06,
118 0.06 Thu Jan 02 11:15:01 2003
119 - Added support for authentication
120 - Add documentation for the object tree passed as the RPN
121 member of the search-handler's argument hash.
122 - We actually removed the vacuous Changelog and TODO files
123 back in 0.05. They should never have been here :-)
125 0.05 Tue Feb 05 21:54:30 2002
126 - Add brief documentation of the new handling
129 0.04 Tue Feb 05 21:49:56 2002
130 - Add Changelog (Why? We already have this file!)
131 - Add TODO file (although it's empty!)
132 - Change interface to constructor, and fix test.pl script to
133 use the new interface.
134 - Add support for Scan.
135 - Add support for building GRS-1 records.
136 - Add grs_test.pl test suite for new GRS-1 code.
137 - Add RPN structure to search-handler argument hash.
138 - Add PID element to init, search, fetch and present-handler
139 argument hashes (but not the sort, scan and close-handlers,
141 - Fix typos in documentation.
143 0.03 Thu Nov 09 16:22:00 2000
144 - Add the INSTALL file.
145 - Add support for a present-handler (distinct from fetch).
146 - Remove `$args->{LEN} = length($record)' from the example
147 fetch-handler in the documentation.
148 - Minor corrections to documentation, e.g. add commas after
149 elements in anonymous hash of arguments.
150 - Record syntaxes (formats) are now specified as ASCII OIDs
151 (e.g. "1.2.840.10003.5.10") rather than human-readable
152 strings (e.g. "usmarc")
153 - Add some XS code to support sorting, though it doesn't seem
154 to be finished yet, and is not wired out.
155 - Use symbolic constants (e.g. Z_ElementSetNames_generic
156 instead of hard-wired magic number 1).
157 - Add PEER_NAME element to init-handler argument hash.
158 - Minor changes to ztest.pl.
160 0.02 Mon Sep 11 12:32:00 2000
161 - First released versions
163 0.01 Wed Aug 30 14:54:01 2000
164 - original version; created by h2xs 1.19
167 - When invoking Init callback, set initial values of IMP_ID,
168 IMP_NAME and IMP_VER from the client's Init request.
