3 Revision history for Perl extension Net::Z3950::SimpleServer
6 - When the scan-handler callback returns, do not attempt to
7 copy the terms from Perl structures if the error-code is
8 non-zero (i.e. if an error has occurred). This protects
9 against a segmentation fault when the Perl callback does not
10 explicitly set $args->{NUMBER} = 0 on error.
11 - Some clarifications to documentation.
12 - Correct transcription of string-valued attributes in
14 - Scan handler is now passed RPN as well as TERM, a tree of
15 Perl structures representing the entire scan clause
16 including access-points and other attributes (which are
19 1.06 Fri Aug 10 23:30:00 BST 2007
20 - New global-handle element can be specified when creating a
21 simple-server object and will be passed to all callback
22 functions. This allows global state to be eliminated from
23 SimpleServer applications ... finally!
24 - Search handler now deals correctly with undefined addinfo:
25 previously a (harmless) error message was emitted.
26 - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
27 applications will need if they access SRU/SRW back-end
28 databases and need to report errors.
29 - Add Perl API to yaz_diag_bib1_to_srw(), because it would
32 1.05 Wed Dec 27 13:19:13 CET 2006
33 - Taking new naming convention for YAZ constants into account.
35 1.04 Fri Dec 1 10:48:32 CET 2006
36 - Build such that SimpleServer links to new yaz shared object.
38 1.03 Tue Aug 8 17:27:16 BST 2006
39 - Rely on version 2.1.14 or later of YAZ; this is the first
40 version that reliably passes through the additional
41 information associated with errors generated while serving
42 SRU/W requests. No functional differences since 1.02.
44 1.02 Wed Jul 26 12:09:50 BST 2006
45 - Better support for Open and User/Password authentication.
46 - SimpleServer.xs's rpn2pquery() is now discarded, and YAZ's
47 yaz_rpnquery_to_wrbuf() used instead. This is more robust
48 in dealing with unusual cases such as string-valued
50 - Support for SCHEMA element when fetching records.
52 1.01 Fri Mar 24 12:09:32 GMT 2006
53 - Documentation of release 1.00's SRU/SRW facilities.
54 - Makefile.PL now fails if YAZ version is earlier than 2.0.0,
55 which was the first with SRU/SRW support.
57 1.00 Fri Mar 24 01:20:24 GMT 2006
58 - Support for SRU and SRW. Mostly this is provided by the YAZ
59 GFS, but changes are needed to allow for the case where
60 there is no RPN query (due to absent on invalid <cql2rpn>
61 element in GFS configuration) so that CQL is passed through
62 natively; and also to fake up an {REQ_FORM} and {REP_FORM}
63 parameters set to the "text/xml" OID when this information
64 is not specified by the GFS.
65 (The jump in version number is due to the SRU/W support.)
66 - Include "logging-server.pl" in the distribution: the
67 simplest possible SimpleServer application, which merely
68 logs the client-request data structures.
69 - Makefile.PL is more helpful if yaz-config isn't found.
70 - Explicitly disable prototypes in SimpleServer.xs: makes no
71 difference but suppresses an error message for a cleaner
74 0.08 Mon Jun 14 14:51:01 2004
75 - SimpleServer is now perl 5.8 thread proof
76 - Support for IMP_ID parameter in Init responses. This was
77 actually written a long time ago, but left commented out as
78 the underlying YAZ back-end server didn't support
79 implementation-ID setting. Now that it does (and has done
80 for eighteen months -- since YAZ release 1.8.6 of
81 2002/03/25!), I've finally removed the comments.
82 - Init handler now understands the setting of {ERR_CODE} as
83 more than a boolean success indicator, and also {ERR_STR}.
84 They are now passed back to the client (thanks to recent
85 changes to the YAZ generic front-end server) in accordance
86 with Z39.50 Implementor Agreement 5, found at
87 http://lcweb.loc.gov/z3950/agency/agree/initdiag.html
89 0.07 Fri Jan 03 10:12:15 2003
90 - Applied Dave Mitchell's (davem@fdgroup.com) GRS-1 parsing patch.
91 Thanks Dave, and sorry it didn't find its way to release 0.06,
94 0.06 Thu Jan 02 11:15:01 2003
95 - Added support for authentication
96 - Add documentation for the object tree passed as the RPN
97 member of the search-handler's argument hash.
98 - We actually removed the vacuous Changelog and TODO files
99 back in 0.05. They should never have been here :-)
101 0.05 Tue Feb 05 21:54:30 2002
102 - Add brief documentation of the new handling
105 0.04 Tue Feb 05 21:49:56 2002
106 - Add Changelog (Why? We already have this file!)
107 - Add TODO file (although it's empty!)
108 - Change interface to constructor, and fix test.pl script to
109 use the new interface.
110 - Add support for Scan.
111 - Add support for building GRS-1 records.
112 - Add grs_test.pl test suite for new GRS-1 code.
113 - Add RPN structure to search-handler argument hash.
114 - Add PID element to init, search, fetch and present-handler
115 argument hashes (but not the sort, scan and close-handlers,
117 - Fix typos in documentation.
119 0.03 Thu Nov 09 16:22:00 2000
120 - Add the INSTALL file.
121 - Add support for a present-handler (distinct from fetch).
122 - Remove `$args->{LEN} = length($record)' from the example
123 fetch-handler in the documentation.
124 - Minor corrections to documentation, e.g. add commas after
125 elements in anonymous hash of arguments.
126 - Record syntaxes (formats) are now specified as ASCII OIDs
127 (e.g. "1.2.840.10003.5.10") rather than human-readable
128 strings (e.g. "usmarc")
129 - Add some XS code to support sorting, though it doesn't seem
130 to be finished yet, and is not wired out.
131 - Use symbolic constants (e.g. Z_ElementSetNames_generic
132 instead of hard-wired magic number 1).
133 - Add PEER_NAME element to init-handler argument hash.
134 - Minor changes to ztest.pl.
