3 Revision history for Perl extension Net::Z3950::ZOOM.
5 1.16 Tue Jan 16 11:18:34 GMT 2007
6 - Require version 2.1.41 or better of YAZ, so that Init
7 Response options are available using
8 $conn->option("init_opt_sort") etc.
9 - Include samples/zoom/zhello.pl to exercise these options.
10 - Add ZOOM_connection_peek_event() and $conn->peek_event().
11 - Require YAZ version 2.1.45, which is the first to provide
12 ZOOM_connection_peek_event().
15 1.15 Fri Dec 1 14:17:49 GMT 2006
16 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
17 INIT is a reserved word in Perl. In version 1.14 and
18 earlier, "require ZOOM" would fail, saying "Too late to run
19 INIT block", and "use ZOOM" would result in
20 ZOOM::Error::INIT having a value equal to its name (why?!)
21 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
22 - Belatedly added documentation for $rec->error() and
25 1.14 Tue Nov 28 17:33:07 GMT 2006
26 - Add $record->error() to return non-surrogate diagnostics,
27 and $record->exception() to return the same information
28 wrapped in a ZOOM::Exception object.
29 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
30 - $conn->error_x() now returns the error-code when called in
31 scalar context, rather than the diagnostic set name.
33 1.13 Sat Nov 4 16:47:00 GMT 2006
34 - ZOOM::Connection::create() may now take either a single
35 argument, which is a ZOOM::Options object, or any even
36 number of argument (including zero), which are key => value
37 pairs of options to set.
38 - ZOOM::Connection::new(), having been refactored to use
39 create(), can now also take a ZOOM::Options argument.
40 - Documentation now includes information on specifying SRW,
41 SRU-over-GET and SRU-over-POST connections.
42 - ZOOM::ResultSet::record() throws a diagnostic if asked to
43 retrieve records out of range for the result-set.
44 - All tests against indexdata.com are now explicitly against
45 z3950.indexdata.com, as the identity of the former name has
48 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
49 - Include the useful example program samples/zoom/zselect,
50 which is installed as part of "make install".
51 - Add ZOOM_connection_is_idle() and $conn->is_idle().
52 - Require YAZ version 2.1.35, which is the first to provide
53 ZOOM_connection_is_idle().
54 - Fix bug in ZOOM::Connection class code that made the
55 difficult to subclass -- when called as
56 $class->SUPER::new(@_), the constructor blessed the new
57 object into ZOOM::Connection rather than info the subclass.
59 1.11 Thu Aug 31 16:47:53 BST 2006
60 - Require YAZ version 2.1.17, which has important ZOOM-C
62 - Do not use "-Wdeclaration-after-statement" compiler option,
63 since this supported only by GCC (and only recent versions).
65 1.10 Thu Jun 15 16:42:47 BST 2006
66 - No functional changes, but use Adam's modified API to
67 ZOOM_query_ccl2rpn(). This incompatible change means that
68 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
70 1.09 Tue Jun 13 17:44:43 2006
71 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
72 client-side CCL compilation.
73 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
74 compiler functionality as a Query subclass. This allows
75 client-side CCL to be used for both search and scan.
76 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
77 returned by the client-side CCL facilities.
78 - Supply a sample CCL profile file: samples/ccl/default.bib,
79 copied from the same-named file distributed with YAZ.
80 - The test-scripts t/12-query.t and t/22-query.t are extended
81 to also test client-side CCL searching.
82 - The test-scripts t/15-scan.t and t/25-scan.t are extended
83 to also test client-side CCL scanning.
84 - Documentation updated to describe use of CCL.
85 - Add a nice, simple update client: samples/zoom/update.pl
87 1.08 Thu May 11 22:40:41 BST 2006
88 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
89 bugfix: the old reliance on 2.0.11 was merely a typo.
91 1.07 Thu May 11 17:45:37 BST 2006
92 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
93 refuses to build if it's not present. Thanks to "gregor"
94 (an otherwise anonymous CPAN tester) for notifying me of the
95 previously poor reporting of failure when running against an
97 - No changes to functionality or documentation.
99 1.06 Wed Apr 19 21:11:52 BST 2006
100 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
101 the heck GCC allows this by default I will never understand.
102 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
103 on -Wdeclaration-after-statement, which makes mixed
104 statement/declaration illegal.
106 1.05 Wed Apr 12 13:31:27 BST 2006
107 - Implementation of asynchronous events! The Net::Z3950::ZOOM
108 interface provides this through the event, last_event() and
109 event_str() functions. The ZOOM interface provides it
110 through the ZOOM::event() and ZOOM:event_str() functions,
111 and the ZOOM::Connection class's last_event() function.
112 - New sample programs added illustrating both asynchronous
113 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
114 samples/zoom/zoomtst3.pl respectively. Additional sample
115 programs "async.pl" and "trivial-async.pl" for the ZOOM
116 interface only, the latter being a "shortest possible
117 broadcast search application".
118 - Added documentation on writing asynchronous applications.
119 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
120 events on an asynchronous connection.
121 - Fix ZOOM::Connection::new so that options are handled in
122 accordance with the documentation: applied _before_ the
123 connection is forged, so that "async" and similar options
126 1.04 Mon Apr 3 14:56:11 BST 2006
127 - The ZOOM-Perl layer now provides access to the underlying
128 ZOOM-C's character-translation functionality, through new
129 optional arguments to ZOOM::Record's render() and raw()
130 methods, and a new underlying get() method.
132 1.03 Thu Mar 9 12:55:23 GMT 2006
133 - Allow additional key => value pairs as arguments to the
134 ZOOM::Connectoion constructor; these are added as Connection
135 options before the protocol connection is forged.
137 1.02 Thu Mar 9 11:36:55 GMT 2006
138 - Add interface to yaz_version().
139 - Emit big warning at startup time if YAZ version is less than
140 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
141 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
142 - Fix incorrect ZOOM-package URL in documentation.
143 - Fix typo ("createdb" package) in documentation.
144 - The ZOOM::Connection constructor may now be called with only
145 a single argument (host-string) and does not require a
146 dummy port-number argument.
148 1.01 Thu Dec 22 14:13:34 GMT 2005
149 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
150 so that the declarations they begin with are at the start of
151 the block. This avoid mixed code/declarations. (The
152 "correct" solution is to use INIT: clauses in the XS file,
153 but they don't seem to work: the code in them is slapped
154 down right next to the CODE:, so declarations are not
155 acceptable there either.)
156 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
157 uses a query object to indicate the start-term. This opens
158 the way for using CQL queries for scanning once the
159 underlying ZOOM-C code supports this.
160 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
161 method scan() is renamed scan_pqf(), and a new scan() method
162 is introduced which calls the underlying scan1() function.
163 Thus the scan()/scan_pqf() dichotomy is consistent with that
164 between search()/search_pqf().
165 - The tests t/15-scan.t and t/25-scan.t now also test for
166 scanning by CQL query. To support these tests, a new files
167 is added to the distribution, "samples/cql/pqf.properties"
168 - Remove nonsensical clause about CQL sort-specifications from
170 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
171 client-side CQL compilation.
172 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
173 compiler functionality as a Query subclass.
174 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
175 returned by the client-side CQL facilities.
176 - The test-scripts t/12-query.t and t/22-query.t are extended
177 to also test client-side CQL compilation.
178 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
180 - Add new ZOOM::Log class for logging, providing aliases for
181 the functions in the Net::Z3950::ZOOM layer.
182 - Add diagnostic set to rendering of Exception objects.
183 - Documentation added for CQL compilation and logging.
185 1.00 Wed Dec 14 11:18:33 GMT 2005
186 - First distributed version.
188 0.01 Fri Oct 7 16:14:20 2005
189 - original version; created by h2xs 1.23 with options
190 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
191 --omit-constant --skip-exporter --skip-ppport \
192 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
196 To be done in future releases:
197 - Complete, test and document "update.pl"
198 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
199 _when_ appropriate, e.g. for "render" but probably not for
200 "database" and "syntax".
201 - Create old-style Net::Z3950 compatibility layer.
202 - Fix memory leaks in callback functions for option sets.
203 - Fix limitation that option-set callback functions must be
204 specified as strings containing package-qualified function
