3 Revision history for Perl extension Net::Z3950::SimpleServer
5 1.08 Mon Sep 10 12:15:29 BST 2007
6 - *Sigh* Fix mixed statement/declaration.
8 1.07 Sat Sep 1 10:31:26 BST 2007
9 - When the scan-handler callback returns, do not attempt to
10 copy the terms from Perl structures if the error-code is
11 non-zero (i.e. if an error has occurred). This protects
12 against a segmentation fault when the Perl callback does not
13 explicitly set $args->{NUMBER} = 0 on error.
14 - Correct transcription of string-valued attributes in
16 - Scan handler is now passed RPN as well as TERM, a tree of
17 Perl structures representing the entire scan clause
18 including access-points and other attributes (which are
20 - The various classes used to represent nodes in the RPN query
21 tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
22 Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
23 Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
24 share a newly introduced superclass Net::Z3950::RPN::Node,
25 making it possible to write methods that apply to all node
27 - A utility method toPQF() is provided for
28 Net::Z3950::RPN::Node, enabling the RPN tree to be converted
29 back into a flat PQF query.
30 - Add support for the Delete Result Set service.
31 - Add documentation for the Sort service.
32 - Some clarifications to documentation.
34 1.06 Fri Aug 10 23:30:00 BST 2007
35 - New global-handle element can be specified when creating a
36 simple-server object and will be passed to all callback
37 functions. This allows global state to be eliminated from
38 SimpleServer applications ... finally!
39 - Search handler now deals correctly with undefined addinfo:
40 previously a (harmless) error message was emitted.
41 - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
42 applications will need if they access SRU/SRW back-end
43 databases and need to report errors.
44 - Add Perl API to yaz_diag_bib1_to_srw(), because it would
47 1.05 Wed Dec 27 13:19:13 CET 2006
48 - Taking new naming convention for YAZ constants into account.
50 1.04 Fri Dec 1 10:48:32 CET 2006
51 - Build such that SimpleServer links to new yaz shared object.
53 1.03 Tue Aug 8 17:27:16 BST 2006
54 - Rely on version 2.1.14 or later of YAZ; this is the first
55 version that reliably passes through the additional
56 information associated with errors generated while serving
57 SRU/W requests. No functional differences since 1.02.
59 1.02 Wed Jul 26 12:09:50 BST 2006
60 - Better support for Open and User/Password authentication.
61 - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's
62 yaz_rpnquery_to_wrbuf() used instead. This is more robust
63 in dealing with unusual cases such as string-valued
65 - Support for SCHEMA element when fetching records.
67 1.01 Fri Mar 24 12:09:32 GMT 2006
68 - Documentation of release 1.00's SRU/SRW facilities.
69 - Makefile.PL now fails if YAZ version is earlier than 2.0.0,
70 which was the first with SRU/SRW support.
72 1.00 Fri Mar 24 01:20:24 GMT 2006
73 - Support for SRU and SRW. Mostly this is provided by the YAZ
74 GFS, but changes are needed to allow for the case where
75 there is no RPN query (due to absent on invalid <cql2rpn>
76 element in GFS configuration) so that CQL is passed through
77 natively; and also to fake up an {REQ_FORM} and {REP_FORM}
78 parameters set to the "text/xml" OID when this information
79 is not specified by the GFS.
80 (The jump in version number is due to the SRU/W support.)
81 - Include "logging-server.pl" in the distribution: the
82 simplest possible SimpleServer application, which merely
83 logs the client-request data structures.
84 - Makefile.PL is more helpful if yaz-config isn't found.
85 - Explicitly disable prototypes in SimpleServer.xs: makes no
86 difference but suppresses an error message for a cleaner
89 0.08 Mon Jun 14 14:51:01 2004
90 - SimpleServer is now perl 5.8 thread proof
91 - Support for IMP_ID parameter in Init responses. This was
92 actually written a long time ago, but left commented out as
93 the underlying YAZ back-end server didn't support
94 implementation-ID setting. Now that it does (and has done
95 for eighteen months -- since YAZ release 1.8.6 of
96 2002/03/25!), I've finally removed the comments.
97 - Init handler now understands the setting of {ERR_CODE} as
98 more than a boolean success indicator, and also {ERR_STR}.
99 They are now passed back to the client (thanks to recent
100 changes to the YAZ generic front-end server) in accordance
101 with Z39.50 Implementor Agreement 5, found at
102 http://lcweb.loc.gov/z3950/agency/agree/initdiag.html
104 0.07 Fri Jan 03 10:12:15 2003
105 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch.
106 Thanks Dave, and sorry it didn't find its way to release 0.06,
109 0.06 Thu Jan 02 11:15:01 2003
110 - Added support for authentication
111 - Add documentation for the object tree passed as the RPN
112 member of the search-handler's argument hash.
113 - We actually removed the vacuous Changelog and TODO files
114 back in 0.05. They should never have been here :-)
116 0.05 Tue Feb 05 21:54:30 2002
117 - Add brief documentation of the new handling
120 0.04 Tue Feb 05 21:49:56 2002
121 - Add Changelog (Why? We already have this file!)
122 - Add TODO file (although it's empty!)
123 - Change interface to constructor, and fix test.pl script to
124 use the new interface.
125 - Add support for Scan.
126 - Add support for building GRS-1 records.
127 - Add grs_test.pl test suite for new GRS-1 code.
128 - Add RPN structure to search-handler argument hash.
129 - Add PID element to init, search, fetch and present-handler
130 argument hashes (but not the sort, scan and close-handlers,
132 - Fix typos in documentation.
134 0.03 Thu Nov 09 16:22:00 2000
135 - Add the INSTALL file.
136 - Add support for a present-handler (distinct from fetch).
137 - Remove `$args->{LEN} = length($record)' from the example
138 fetch-handler in the documentation.
139 - Minor corrections to documentation, e.g. add commas after
140 elements in anonymous hash of arguments.
141 - Record syntaxes (formats) are now specified as ASCII OIDs
142 (e.g. "1.2.840.10003.5.10") rather than human-readable
143 strings (e.g. "usmarc")
144 - Add some XS code to support sorting, though it doesn't seem
145 to be finished yet, and is not wired out.
146 - Use symbolic constants (e.g. Z_ElementSetNames_generic
147 instead of hard-wired magic number 1).
148 - Add PEER_NAME element to init-handler argument hash.
149 - Minor changes to ztest.pl.
151 0.02 Mon Sep 11 12:32:00 2000
152 - First released versions
154 0.01 Wed Aug 30 14:54:01 2000
155 - original version; created by h2xs 1.19
