3 Revision history for Perl extension Net::Z3950::ZOOM.
6 - Add $record->error() to return non-surrogate diagnostics,
7 and $record->exception() to return the same information
8 wrapped in a ZOOM::Exception object.
9 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
10 - $conn->error_x() now returns the error-code when called in
11 scalar context, rather than the diagnostic set name.
13 1.13 Sat Nov 4 16:47:00 GMT 2006
14 - ZOOM::Connection::create() may now take either a single
15 argument, which is a ZOOM::Options object, or any even
16 number of argument (including zero), which are key => value
17 pairs of options to set.
18 - ZOOM::Connection::new(), having been refactored to use
19 create(), can now also take a ZOOM::Options argument.
20 - Documentation now includes information on specifying SRW,
21 SRU-over-GET and SRU-over-POST connections.
22 - ZOOM::ResultSet::record() throws a diagnostic if asked to
23 retrieve records out of range for the result-set.
24 - All tests against indexdata.com are now explicitly against
25 z3950.indexdata.com, as the identity of the former name has
28 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
29 - Include the useful example program samples/zoom/zselect,
30 which is installed as part of "make install".
31 - Add ZOOM_connection_is_idle() and $conn->is_idle().
32 - Require YAZ version 2.1.35, which is the first to provide
33 ZOOM_connection_is_idle().
34 - Fix bug in ZOOM::Connection class code that made the
35 difficult to subclass -- when called as
36 $class->SUPER::new(@_), the constructor blessed the new
37 object into ZOOM::Connection rather than info the subclass.
39 1.11 Thu Aug 31 16:47:53 BST 2006
40 - Require YAZ version 2.1.17, which has important ZOOM-C
42 - Do not use "-Wdeclaration-after-statement" compiler option,
43 since this supported only by GCC (and only recent versions).
45 1.10 Thu Jun 15 16:42:47 BST 2006
46 - No functional changes, but use Adam's modified API to
47 ZOOM_query_ccl2rpn(). This incompatible change means that
48 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
50 1.09 Tue Jun 13 17:44:43 2006
51 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
52 client-side CCL compilation.
53 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
54 compiler functionality as a Query subclass. This allows
55 client-side CCL to be used for both search and scan.
56 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
57 returned by the client-side CCL facilities.
58 - Supply a sample CCL profile file: samples/ccl/default.bib,
59 copied from the same-named file distributed with YAZ.
60 - The test-scripts t/12-query.t and t/22-query.t are extended
61 to also test client-side CCL searching.
62 - The test-scripts t/15-scan.t and t/25-scan.t are extended
63 to also test client-side CCL scanning.
64 - Documentation updated to describe use of CCL.
65 - Add a nice, simple update client: samples/zoom/update.pl
67 1.08 Thu May 11 22:40:41 BST 2006
68 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
69 bugfix: the old reliance on 2.0.11 was merely a typo.
71 1.07 Thu May 11 17:45:37 BST 2006
72 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
73 refuses to build if it's not present. Thanks to "gregor"
74 (an otherwise anonymous CPAN tester) for notifying me of the
75 previously poor reporting of failure when running against an
77 - No changes to functionality or documentation.
79 1.06 Wed Apr 19 21:11:52 BST 2006
80 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
81 the heck GCC allows this by default I will never understand.
82 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
83 on -Wdeclaration-after-statement, which makes mixed
84 statement/declaration illegal.
86 1.05 Wed Apr 12 13:31:27 BST 2006
87 - Implementation of asynchronous events! The Net::Z3950::ZOOM
88 interface provides this through the event, last_event() and
89 event_str() functions. The ZOOM interface provides it
90 through the ZOOM::event() and ZOOM:event_str() functions,
91 and the ZOOM::Connection class's last_event() function.
92 - New sample programs added illustrating both asynchronous
93 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
94 samples/zoom/zoomtst3.pl respectively. Additional sample
95 programs "async.pl" and "trivial-async.pl" for the ZOOM
96 interface only, the latter being a "shortest possible
97 broadcast search application".
98 - Added documentation on writing asynchronous applications.
99 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
100 events on an asynchronous connection.
101 - Fix ZOOM::Connection::new so that options are handled in
102 accordance with the documentation: applied _before_ the
103 connection is forged, so that "async" and similar options
106 1.04 Mon Apr 3 14:56:11 BST 2006
107 - The ZOOM-Perl layer now provides access to the underlying
108 ZOOM-C's character-translation functionality, through new
109 optional arguments to ZOOM::Record's render() and raw()
110 methods, and a new underlying get() method.
112 1.03 Thu Mar 9 12:55:23 GMT 2006
113 - Allow additional key => value pairs as arguments to the
114 ZOOM::Connectoion constructor; these are added as Connection
115 options before the protocol connection is forged.
117 1.02 Thu Mar 9 11:36:55 GMT 2006
118 - Add interface to yaz_version().
119 - Emit big warning at startup time if YAZ version is less than
120 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
121 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
122 - Fix incorrect ZOOM-package URL in documentation.
123 - Fix typo ("createdb" package) in documentation.
124 - The ZOOM::Connection constructor may now be called with only
125 a single argument (host-string) and does not require a
126 dummy port-number argument.
128 1.01 Thu Dec 22 14:13:34 GMT 2005
129 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
130 so that the declarations they begin with are at the start of
131 the block. This avoid mixed code/declarations. (The
132 "correct" solution is to use INIT: clauses in the XS file,
133 but they don't seem to work: the code in them is slapped
134 down right next to the CODE:, so declarations are not
135 acceptable there either.)
136 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
137 uses a query object to indicate the start-term. This opens
138 the way for using CQL queries for scanning once the
139 underlying ZOOM-C code supports this.
140 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
141 method scan() is renamed scan_pqf(), and a new scan() method
142 is introduced which calls the underlying scan1() function.
143 Thus the scan()/scan_pqf() dichotomy is consistent with that
144 between search()/search_pqf().
145 - The tests t/15-scan.t and t/25-scan.t now also test for
146 scanning by CQL query. To support these tests, a new files
147 is added to the distribution, "samples/cql/pqf.properties"
148 - Remove nonsensical clause about CQL sort-specifications from
150 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
151 client-side CQL compilation.
152 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
153 compiler functionality as a Query subclass.
154 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
155 returned by the client-side CQL facilities.
156 - The test-scripts t/12-query.t and t/22-query.t are extended
157 to also test client-side CQL compilation.
158 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
160 - Add new ZOOM::Log class for logging, providing aliases for
161 the functions in the Net::Z3950::ZOOM layer.
162 - Add diagnostic set to rendering of Exception objects.
163 - Documentation added for CQL compilation and logging.
165 1.00 Wed Dec 14 11:18:33 GMT 2005
166 - First distributed version.
168 0.01 Fri Oct 7 16:14:20 2005
169 - original version; created by h2xs 1.23 with options
170 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
171 --omit-constant --skip-exporter --skip-ppport \
172 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
176 To be done in future releases:
177 - Complete, test and document "update.pl"
178 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
179 _when_ appropriate, e.g. for "render" but probably not for
180 "database" and "syntax".
181 - Create old-style Net::Z3950 compatibility layer.
182 - Fix memory leaks in callback functions for option sets.
183 - Fix limitation that option-set callback functions must be
184 specified as strings containing package-qualified function
