3 Revision history for Perl extension Net::Z3950::ZOOM.
6 - Better Debian packaging: use "make debian" to create new
7 "debian-output" directory containing .deb package file,
9 - Clear up a few warnings in ZOOM.xs
11 1.21 Mon Oct 29 12:07:25 GMT 2007
12 - In the "typemap" file's handling of opaquechar*, use STRLEN
13 type for _unused_len in instead of unsigned: this prevents a
14 (possibly serious) warning on some 64-bit architectures,
15 although applications that do not use the option_binary()
16 methods will be safe with the previous release.
17 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
18 of preventing undeclared-function warnings that some users
19 have reported but which I have been unable to reproduce.
21 1.20 Fri Sep 21 17:51:55 BST 2007
22 - Add new sample program, samples/zoom/zoomscan.pl
23 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
24 the end of the command-line, so that (for example) you can
25 specify a non-USMARC record syntax.
26 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
27 ZOOM::diag_srw_str() to map SRW diagnostic codes into
28 human-readable messages.
29 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
30 the error message, if it is undefined, for SRW errors.
31 - The render() method of ZOOM::Exception(), and therefore the
32 overloaded stringifying operator, deals with exceptions that
34 - Corrected the scan parts of the test-suite that use CQL so
35 that they explicitly perform client-side CQL compilation and
36 send the resulting Type-1 query. Previously, these tests
37 were (accidentally) requesting that CQL be sent as-is to the
38 server, but this mistake was being masked by an error in
39 older versions of ZOOM-C that compiled client-side anyway!
41 1.19 Mon Jul 9 14:09:31 BST 2007
42 - Add $conn->exception() method.
43 - Set version number for Net::Z3950 to 0.99 -- less than the
44 1.0 version number that will be used when it successfully
45 emulates the old Net::Z3950 module, but superseding the last
46 release, 0.51, of that module.
47 - Include samples/zoom/zdump.pl in distribution.
48 - Add "irspy" namespace to samples/zoom/zselect
50 1.18 Mon Feb 26 14:57:48 GMT 2007
51 - When a connection is in asynchronous mode, failing
52 operations (search, scan, etc.) no longer throw exceptions.
53 This is because the event-loop in asychronous applications
54 needs to check for errors anyway, in case the server has
55 returned high-level diagnostics such as "unsupported use
56 attribute". So this check within the event-loop is now the
57 only place where error-checking need be done.
58 - Add new public ZOOM::Connection() function, check(), which
59 throws an exception if an error is pending (even if the
60 connection is asynchronous).
61 - New YAZ logging level, "zoom_check", notes when errors are
62 detected and either left unreported (asynchronous
63 connections) or thrown as exception (synchronous).
65 1.17 Thu Feb 22 20:38:45 GMT 2007
66 - Change Net::Z3950::ZOOM::event() to allocate its array of
67 connection pointers dynamically, so there is no longer an
68 arbitrary limit of 100.
69 - New connection-level option "_check_debug" emits messages on
70 standard error when checking a connection find an error that
71 is about to result in throwing an exception. There is no
72 reason for you ever to use this, though -- pretend you don't
75 1.16 Tue Jan 16 11:18:34 GMT 2007
76 - Require version 2.1.41 or better of YAZ, so that Init
77 Response options are available using
78 $conn->option("init_opt_sort") etc.
79 - Include samples/zoom/zhello.pl to exercise these options.
80 - Add ZOOM_connection_peek_event() and $conn->peek_event().
81 - Require YAZ version 2.1.45, which is the first to provide
82 ZOOM_connection_peek_event().
84 1.15 Fri Dec 1 14:17:49 GMT 2006
85 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
86 INIT is a reserved word in Perl. In version 1.14 and
87 earlier, "require ZOOM" would fail, saying "Too late to run
88 INIT block", and "use ZOOM" would result in
89 ZOOM::Error::INIT having a value equal to its name (why?!)
90 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
91 - Belatedly added documentation for $rec->error() and
94 1.14 Tue Nov 28 17:33:07 GMT 2006
95 - Add $record->error() to return non-surrogate diagnostics,
96 and $record->exception() to return the same information
97 wrapped in a ZOOM::Exception object.
98 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
99 - $conn->error_x() now returns the error-code when called in
100 scalar context, rather than the diagnostic set name.
102 1.13 Sat Nov 4 16:47:00 GMT 2006
103 - ZOOM::Connection::create() may now take either a single
104 argument, which is a ZOOM::Options object, or any even
105 number of argument (including zero), which are key => value
106 pairs of options to set.
107 - ZOOM::Connection::new(), having been refactored to use
108 create(), can now also take a ZOOM::Options argument.
109 - Documentation now includes information on specifying SRW,
110 SRU-over-GET and SRU-over-POST connections.
111 - ZOOM::ResultSet::record() throws a diagnostic if asked to
112 retrieve records out of range for the result-set.
113 - All tests against indexdata.com are now explicitly against
114 z3950.indexdata.com, as the identity of the former name has
117 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
118 - Include the useful example program samples/zoom/zselect,
119 which is installed as part of "make install".
120 - Add ZOOM_connection_is_idle() and $conn->is_idle().
121 - Require YAZ version 2.1.35, which is the first to provide
122 ZOOM_connection_is_idle().
123 - Fix bug in ZOOM::Connection class code that made the
124 difficult to subclass -- when called as
125 $class->SUPER::new(@_), the constructor blessed the new
126 object into ZOOM::Connection rather than info the subclass.
128 1.11 Thu Aug 31 16:47:53 BST 2006
129 - Require YAZ version 2.1.17, which has important ZOOM-C
131 - Do not use "-Wdeclaration-after-statement" compiler option,
132 since this supported only by GCC (and only recent versions).
134 1.10 Thu Jun 15 16:42:47 BST 2006
135 - No functional changes, but use Adam's modified API to
136 ZOOM_query_ccl2rpn(). This incompatible change means that
137 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
139 1.09 Tue Jun 13 17:44:43 2006
140 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
141 client-side CCL compilation.
142 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
143 compiler functionality as a Query subclass. This allows
144 client-side CCL to be used for both search and scan.
145 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
146 returned by the client-side CCL facilities.
147 - Supply a sample CCL profile file: samples/ccl/default.bib,
148 copied from the same-named file distributed with YAZ.
149 - The test-scripts t/12-query.t and t/22-query.t are extended
150 to also test client-side CCL searching.
151 - The test-scripts t/15-scan.t and t/25-scan.t are extended
152 to also test client-side CCL scanning.
153 - Documentation updated to describe use of CCL.
154 - Add a nice, simple update client: samples/zoom/update.pl
156 1.08 Thu May 11 22:40:41 BST 2006
157 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
158 bugfix: the old reliance on 2.0.11 was merely a typo.
160 1.07 Thu May 11 17:45:37 BST 2006
161 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
162 refuses to build if it's not present. Thanks to "gregor"
163 (an otherwise anonymous CPAN tester) for notifying me of the
164 previously poor reporting of failure when running against an
166 - No changes to functionality or documentation.
168 1.06 Wed Apr 19 21:11:52 BST 2006
169 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
170 the heck GCC allows this by default I will never understand.
171 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
172 on -Wdeclaration-after-statement, which makes mixed
173 statement/declaration illegal.
175 1.05 Wed Apr 12 13:31:27 BST 2006
176 - Implementation of asynchronous events! The Net::Z3950::ZOOM
177 interface provides this through the event, last_event() and
178 event_str() functions. The ZOOM interface provides it
179 through the ZOOM::event() and ZOOM:event_str() functions,
180 and the ZOOM::Connection class's last_event() function.
181 - New sample programs added illustrating both asynchronous
182 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
183 samples/zoom/zoomtst3.pl respectively. Additional sample
184 programs "async.pl" and "trivial-async.pl" for the ZOOM
185 interface only, the latter being a "shortest possible
186 broadcast search application".
187 - Added documentation on writing asynchronous applications.
188 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
189 events on an asynchronous connection.
190 - Fix ZOOM::Connection::new so that options are handled in
191 accordance with the documentation: applied _before_ the
192 connection is forged, so that "async" and similar options
195 1.04 Mon Apr 3 14:56:11 BST 2006
196 - The ZOOM-Perl layer now provides access to the underlying
197 ZOOM-C's character-translation functionality, through new
198 optional arguments to ZOOM::Record's render() and raw()
199 methods, and a new underlying get() method.
201 1.03 Thu Mar 9 12:55:23 GMT 2006
202 - Allow additional key => value pairs as arguments to the
203 ZOOM::Connectoion constructor; these are added as Connection
204 options before the protocol connection is forged.
206 1.02 Thu Mar 9 11:36:55 GMT 2006
207 - Add interface to yaz_version().
208 - Emit big warning at startup time if YAZ version is less than
209 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
210 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
211 - Fix incorrect ZOOM-package URL in documentation.
212 - Fix typo ("createdb" package) in documentation.
213 - The ZOOM::Connection constructor may now be called with only
214 a single argument (host-string) and does not require a
215 dummy port-number argument.
217 1.01 Thu Dec 22 14:13:34 GMT 2005
218 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
219 so that the declarations they begin with are at the start of
220 the block. This avoid mixed code/declarations. (The
221 "correct" solution is to use INIT: clauses in the XS file,
222 but they don't seem to work: the code in them is slapped
223 down right next to the CODE:, so declarations are not
224 acceptable there either.)
225 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
226 uses a query object to indicate the start-term. This opens
227 the way for using CQL queries for scanning once the
228 underlying ZOOM-C code supports this.
229 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
230 method scan() is renamed scan_pqf(), and a new scan() method
231 is introduced which calls the underlying scan1() function.
232 Thus the scan()/scan_pqf() dichotomy is consistent with that
233 between search()/search_pqf().
234 - The tests t/15-scan.t and t/25-scan.t now also test for
235 scanning by CQL query. To support these tests, a new files
236 is added to the distribution, "samples/cql/pqf.properties"
237 - Remove nonsensical clause about CQL sort-specifications from
239 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
240 client-side CQL compilation.
241 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
242 compiler functionality as a Query subclass.
243 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
244 returned by the client-side CQL facilities.
245 - The test-scripts t/12-query.t and t/22-query.t are extended
246 to also test client-side CQL compilation.
247 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
249 - Add new ZOOM::Log class for logging, providing aliases for
250 the functions in the Net::Z3950::ZOOM layer.
251 - Add diagnostic set to rendering of Exception objects.
252 - Documentation added for CQL compilation and logging.
254 1.00 Wed Dec 14 11:18:33 GMT 2005
255 - First distributed version.
257 0.01 Fri Oct 7 16:14:20 2005
258 - original version; created by h2xs 1.23 with options
259 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
260 --omit-constant --skip-exporter --skip-ppport \
261 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
265 To be done in future releases:
266 - Complete, test and document "update.pl"
267 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
268 _when_ appropriate, e.g. for "render" but probably not for
269 "database" and "syntax".
270 - Create old-style Net::Z3950 compatibility layer.
271 - Fix memory leaks in callback functions for option sets.
272 - Fix limitation that option-set callback functions must be
273 specified as strings containing package-qualified function
