3 Revision history for Perl extension Net::Z3950::ZOOM.
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.
11 1.15 Fri Dec 1 14:17:49 GMT 2006
12 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
13 INIT is a reserved word in Perl. In version 1.14 and
14 earlier, "require ZOOM" would fail, saying "Too late to run
15 INIT block", and "use ZOOM" would result in
16 ZOOM::Error::INIT having a value equal to its name (why?!)
17 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
18 - Belatedly added documentation for $rec->error() and
21 1.14 Tue Nov 28 17:33:07 GMT 2006
22 - Add $record->error() to return non-surrogate diagnostics,
23 and $record->exception() to return the same information
24 wrapped in a ZOOM::Exception object.
25 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
26 - $conn->error_x() now returns the error-code when called in
27 scalar context, rather than the diagnostic set name.
29 1.13 Sat Nov 4 16:47:00 GMT 2006
30 - ZOOM::Connection::create() may now take either a single
31 argument, which is a ZOOM::Options object, or any even
32 number of argument (including zero), which are key => value
33 pairs of options to set.
34 - ZOOM::Connection::new(), having been refactored to use
35 create(), can now also take a ZOOM::Options argument.
36 - Documentation now includes information on specifying SRW,
37 SRU-over-GET and SRU-over-POST connections.
38 - ZOOM::ResultSet::record() throws a diagnostic if asked to
39 retrieve records out of range for the result-set.
40 - All tests against indexdata.com are now explicitly against
41 z3950.indexdata.com, as the identity of the former name has
44 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
45 - Include the useful example program samples/zoom/zselect,
46 which is installed as part of "make install".
47 - Add ZOOM_connection_is_idle() and $conn->is_idle().
48 - Require YAZ version 2.1.35, which is the first to provide
49 ZOOM_connection_is_idle().
50 - Fix bug in ZOOM::Connection class code that made the
51 difficult to subclass -- when called as
52 $class->SUPER::new(@_), the constructor blessed the new
53 object into ZOOM::Connection rather than info the subclass.
55 1.11 Thu Aug 31 16:47:53 BST 2006
56 - Require YAZ version 2.1.17, which has important ZOOM-C
58 - Do not use "-Wdeclaration-after-statement" compiler option,
59 since this supported only by GCC (and only recent versions).
61 1.10 Thu Jun 15 16:42:47 BST 2006
62 - No functional changes, but use Adam's modified API to
63 ZOOM_query_ccl2rpn(). This incompatible change means that
64 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
66 1.09 Tue Jun 13 17:44:43 2006
67 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
68 client-side CCL compilation.
69 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
70 compiler functionality as a Query subclass. This allows
71 client-side CCL to be used for both search and scan.
72 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
73 returned by the client-side CCL facilities.
74 - Supply a sample CCL profile file: samples/ccl/default.bib,
75 copied from the same-named file distributed with YAZ.
76 - The test-scripts t/12-query.t and t/22-query.t are extended
77 to also test client-side CCL searching.
78 - The test-scripts t/15-scan.t and t/25-scan.t are extended
79 to also test client-side CCL scanning.
80 - Documentation updated to describe use of CCL.
81 - Add a nice, simple update client: samples/zoom/update.pl
83 1.08 Thu May 11 22:40:41 BST 2006
84 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
85 bugfix: the old reliance on 2.0.11 was merely a typo.
87 1.07 Thu May 11 17:45:37 BST 2006
88 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
89 refuses to build if it's not present. Thanks to "gregor"
90 (an otherwise anonymous CPAN tester) for notifying me of the
91 previously poor reporting of failure when running against an
93 - No changes to functionality or documentation.
95 1.06 Wed Apr 19 21:11:52 BST 2006
96 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
97 the heck GCC allows this by default I will never understand.
98 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
99 on -Wdeclaration-after-statement, which makes mixed
100 statement/declaration illegal.
102 1.05 Wed Apr 12 13:31:27 BST 2006
103 - Implementation of asynchronous events! The Net::Z3950::ZOOM
104 interface provides this through the event, last_event() and
105 event_str() functions. The ZOOM interface provides it
106 through the ZOOM::event() and ZOOM:event_str() functions,
107 and the ZOOM::Connection class's last_event() function.
108 - New sample programs added illustrating both asynchronous
109 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
110 samples/zoom/zoomtst3.pl respectively. Additional sample
111 programs "async.pl" and "trivial-async.pl" for the ZOOM
112 interface only, the latter being a "shortest possible
113 broadcast search application".
114 - Added documentation on writing asynchronous applications.
115 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
116 events on an asynchronous connection.
117 - Fix ZOOM::Connection::new so that options are handled in
118 accordance with the documentation: applied _before_ the
119 connection is forged, so that "async" and similar options
122 1.04 Mon Apr 3 14:56:11 BST 2006
123 - The ZOOM-Perl layer now provides access to the underlying
124 ZOOM-C's character-translation functionality, through new
125 optional arguments to ZOOM::Record's render() and raw()
126 methods, and a new underlying get() method.
128 1.03 Thu Mar 9 12:55:23 GMT 2006
129 - Allow additional key => value pairs as arguments to the
130 ZOOM::Connectoion constructor; these are added as Connection
131 options before the protocol connection is forged.
133 1.02 Thu Mar 9 11:36:55 GMT 2006
134 - Add interface to yaz_version().
135 - Emit big warning at startup time if YAZ version is less than
136 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
137 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
138 - Fix incorrect ZOOM-package URL in documentation.
139 - Fix typo ("createdb" package) in documentation.
140 - The ZOOM::Connection constructor may now be called with only
141 a single argument (host-string) and does not require a
142 dummy port-number argument.
144 1.01 Thu Dec 22 14:13:34 GMT 2005
145 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
146 so that the declarations they begin with are at the start of
147 the block. This avoid mixed code/declarations. (The
148 "correct" solution is to use INIT: clauses in the XS file,
149 but they don't seem to work: the code in them is slapped
150 down right next to the CODE:, so declarations are not
151 acceptable there either.)
152 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
153 uses a query object to indicate the start-term. This opens
154 the way for using CQL queries for scanning once the
155 underlying ZOOM-C code supports this.
156 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
157 method scan() is renamed scan_pqf(), and a new scan() method
158 is introduced which calls the underlying scan1() function.
159 Thus the scan()/scan_pqf() dichotomy is consistent with that
160 between search()/search_pqf().
161 - The tests t/15-scan.t and t/25-scan.t now also test for
162 scanning by CQL query. To support these tests, a new files
163 is added to the distribution, "samples/cql/pqf.properties"
164 - Remove nonsensical clause about CQL sort-specifications from
166 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
167 client-side CQL compilation.
168 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
169 compiler functionality as a Query subclass.
170 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
171 returned by the client-side CQL facilities.
172 - The test-scripts t/12-query.t and t/22-query.t are extended
173 to also test client-side CQL compilation.
174 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
176 - Add new ZOOM::Log class for logging, providing aliases for
177 the functions in the Net::Z3950::ZOOM layer.
178 - Add diagnostic set to rendering of Exception objects.
179 - Documentation added for CQL compilation and logging.
181 1.00 Wed Dec 14 11:18:33 GMT 2005
182 - First distributed version.
184 0.01 Fri Oct 7 16:14:20 2005
185 - original version; created by h2xs 1.23 with options
186 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
187 --omit-constant --skip-exporter --skip-ppport \
188 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
192 To be done in future releases:
193 - Complete, test and document "update.pl"
194 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
195 _when_ appropriate, e.g. for "render" but probably not for
196 "database" and "syntax".
197 - Create old-style Net::Z3950 compatibility layer.
198 - Fix memory leaks in callback functions for option sets.
199 - Fix limitation that option-set callback functions must be
200 specified as strings containing package-qualified function
