3 Revision history for Perl extension Net::Z3950::ZOOM.
6 - Fix test-suite not to run the "packages" tests against
7 test.indexdata.com, which has gone away, but against
8 z3950.indexdata.com, like the other tests. A new server
9 runs on a different port for these tests.
10 - Rename zdump.pl to zoomdump, and add it to the set of
12 - Switch to git for version control. Not that it should make
13 any difference to the Perl distribution.
14 - Add semicolons to the commented-out sample configuration
15 lines for Windows in Makefile.PL
16 - Include the useful example program
17 samples/zoom-delete-records which is installed as part of
20 1.24 Tue Jun 17 11:31:08 BST 2008
21 - When Net::Z3950::ZOOM::record_get() fetches an XML record
22 because the requested OPAC record is empty, it now wraps it
23 in an OPAC wrapper, making the difference invisible to
26 1.23 Mon Jun 9 14:53:15 BST 2008
27 - Net::Z3950::ZOOM::record_get() now patches around the
28 problem of naughty servers that refuse to return anything
29 for an OPAC record when there is no non-bibliographic part,
30 by falling back on requesting an XML record in such cases.
32 1.22 Tue May 27 14:00:12 BST 2008
33 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
34 _when_ appropriate, e.g. for "render" not for "database" and
36 - Remove the unused $len reference parameter from record_get()
37 and $record->get(): this is now used in the underlying C
38 layer to make Perl strings of the right length, and is of no
39 value higher up the stack.
40 - Fix a bug in ZOOM::ResultSet::records(): requests including
41 the last record in the set were incorrectly declined.
42 - Better Debian packaging: use "make debian" to create new
43 "debian/output" directory containing .deb package file,
45 - Clear up a few warnings in ZOOM.xs
46 - Minor documentation improvements.
48 1.21 Mon Oct 29 12:07:25 GMT 2007
49 - In the "typemap" file's handling of opaquechar*, use STRLEN
50 type for _unused_len in instead of unsigned: this prevents a
51 (possibly serious) warning on some 64-bit architectures,
52 although applications that do not use the option_binary()
53 methods will be safe with the previous release.
54 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
55 of preventing undeclared-function warnings that some users
56 have reported but which I have been unable to reproduce.
58 1.20 Fri Sep 21 17:51:55 BST 2007
59 - Add new sample program, samples/zoom/zoomscan.pl
60 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
61 the end of the command-line, so that (for example) you can
62 specify a non-USMARC record syntax.
63 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
64 ZOOM::diag_srw_str() to map SRW diagnostic codes into
65 human-readable messages.
66 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
67 the error message, if it is undefined, for SRW errors.
68 - The render() method of ZOOM::Exception(), and therefore the
69 overloaded stringifying operator, deals with exceptions that
71 - Corrected the scan parts of the test-suite that use CQL so
72 that they explicitly perform client-side CQL compilation and
73 send the resulting Type-1 query. Previously, these tests
74 were (accidentally) requesting that CQL be sent as-is to the
75 server, but this mistake was being masked by an error in
76 older versions of ZOOM-C that compiled client-side anyway!
78 1.19 Mon Jul 9 14:09:31 BST 2007
79 - Add $conn->exception() method.
80 - Set version number for Net::Z3950 to 0.99 -- less than the
81 1.0 version number that will be used when it successfully
82 emulates the old Net::Z3950 module, but superseding the last
83 release, 0.51, of that module.
84 - Include samples/zoom/zdump.pl in distribution.
85 - Add "irspy" namespace to samples/zoom/zselect
87 1.18 Mon Feb 26 14:57:48 GMT 2007
88 - When a connection is in asynchronous mode, failing
89 operations (search, scan, etc.) no longer throw exceptions.
90 This is because the event-loop in asychronous applications
91 needs to check for errors anyway, in case the server has
92 returned high-level diagnostics such as "unsupported use
93 attribute". So this check within the event-loop is now the
94 only place where error-checking need be done.
95 - Add new public ZOOM::Connection() function, check(), which
96 throws an exception if an error is pending (even if the
97 connection is asynchronous).
98 - New YAZ logging level, "zoom_check", notes when errors are
99 detected and either left unreported (asynchronous
100 connections) or thrown as exception (synchronous).
102 1.17 Thu Feb 22 20:38:45 GMT 2007
103 - Change Net::Z3950::ZOOM::event() to allocate its array of
104 connection pointers dynamically, so there is no longer an
105 arbitrary limit of 100.
106 - New connection-level option "_check_debug" emits messages on
107 standard error when checking a connection find an error that
108 is about to result in throwing an exception. There is no
109 reason for you ever to use this, though -- pretend you don't
112 1.16 Tue Jan 16 11:18:34 GMT 2007
113 - Require version 2.1.41 or better of YAZ, so that Init
114 Response options are available using
115 $conn->option("init_opt_sort") etc.
116 - Include samples/zoom/zhello.pl to exercise these options.
117 - Add ZOOM_connection_peek_event() and $conn->peek_event().
118 - Require YAZ version 2.1.45, which is the first to provide
119 ZOOM_connection_peek_event().
121 1.15 Fri Dec 1 14:17:49 GMT 2006
122 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
123 INIT is a reserved word in Perl. In version 1.14 and
124 earlier, "require ZOOM" would fail, saying "Too late to run
125 INIT block", and "use ZOOM" would result in
126 ZOOM::Error::INIT having a value equal to its name (why?!)
127 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
128 - Belatedly added documentation for $rec->error() and
131 1.14 Tue Nov 28 17:33:07 GMT 2006
132 - Add $record->error() to return non-surrogate diagnostics,
133 and $record->exception() to return the same information
134 wrapped in a ZOOM::Exception object.
135 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
136 - $conn->error_x() now returns the error-code when called in
137 scalar context, rather than the diagnostic set name.
139 1.13 Sat Nov 4 16:47:00 GMT 2006
140 - ZOOM::Connection::create() may now take either a single
141 argument, which is a ZOOM::Options object, or any even
142 number of argument (including zero), which are key => value
143 pairs of options to set.
144 - ZOOM::Connection::new(), having been refactored to use
145 create(), can now also take a ZOOM::Options argument.
146 - Documentation now includes information on specifying SRW,
147 SRU-over-GET and SRU-over-POST connections.
148 - ZOOM::ResultSet::record() throws a diagnostic if asked to
149 retrieve records out of range for the result-set.
150 - All tests against indexdata.com are now explicitly against
151 z3950.indexdata.com, as the identity of the former name has
154 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
155 - Include the useful example program samples/zoom/zselect,
156 which is installed as part of "make install".
157 - Add ZOOM_connection_is_idle() and $conn->is_idle().
158 - Require YAZ version 2.1.35, which is the first to provide
159 ZOOM_connection_is_idle().
160 - Fix bug in ZOOM::Connection class code that made the
161 difficult to subclass -- when called as
162 $class->SUPER::new(@_), the constructor blessed the new
163 object into ZOOM::Connection rather than info the subclass.
165 1.11 Thu Aug 31 16:47:53 BST 2006
166 - Require YAZ version 2.1.17, which has important ZOOM-C
168 - Do not use "-Wdeclaration-after-statement" compiler option,
169 since this supported only by GCC (and only recent versions).
171 1.10 Thu Jun 15 16:42:47 BST 2006
172 - No functional changes, but use Adam's modified API to
173 ZOOM_query_ccl2rpn(). This incompatible change means that
174 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
176 1.09 Tue Jun 13 17:44:43 2006
177 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
178 client-side CCL compilation.
179 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
180 compiler functionality as a Query subclass. This allows
181 client-side CCL to be used for both search and scan.
182 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
183 returned by the client-side CCL facilities.
184 - Supply a sample CCL profile file: samples/ccl/default.bib,
185 copied from the same-named file distributed with YAZ.
186 - The test-scripts t/12-query.t and t/22-query.t are extended
187 to also test client-side CCL searching.
188 - The test-scripts t/15-scan.t and t/25-scan.t are extended
189 to also test client-side CCL scanning.
190 - Documentation updated to describe use of CCL.
191 - Add a nice, simple update client: samples/zoom/update.pl
193 1.08 Thu May 11 22:40:41 BST 2006
194 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
195 bugfix: the old reliance on 2.0.11 was merely a typo.
197 1.07 Thu May 11 17:45:37 BST 2006
198 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
199 refuses to build if it's not present. Thanks to "gregor"
200 (an otherwise anonymous CPAN tester) for notifying me of the
201 previously poor reporting of failure when running against an
203 - No changes to functionality or documentation.
205 1.06 Wed Apr 19 21:11:52 BST 2006
206 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
207 the heck GCC allows this by default I will never understand.
208 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
209 on -Wdeclaration-after-statement, which makes mixed
210 statement/declaration illegal.
212 1.05 Wed Apr 12 13:31:27 BST 2006
213 - Implementation of asynchronous events! The Net::Z3950::ZOOM
214 interface provides this through the event, last_event() and
215 event_str() functions. The ZOOM interface provides it
216 through the ZOOM::event() and ZOOM:event_str() functions,
217 and the ZOOM::Connection class's last_event() function.
218 - New sample programs added illustrating both asynchronous
219 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
220 samples/zoom/zoomtst3.pl respectively. Additional sample
221 programs "async.pl" and "trivial-async.pl" for the ZOOM
222 interface only, the latter being a "shortest possible
223 broadcast search application".
224 - Added documentation on writing asynchronous applications.
225 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
226 events on an asynchronous connection.
227 - Fix ZOOM::Connection::new so that options are handled in
228 accordance with the documentation: applied _before_ the
229 connection is forged, so that "async" and similar options
232 1.04 Mon Apr 3 14:56:11 BST 2006
233 - The ZOOM-Perl layer now provides access to the underlying
234 ZOOM-C's character-translation functionality, through new
235 optional arguments to ZOOM::Record's render() and raw()
236 methods, and a new underlying get() method.
238 1.03 Thu Mar 9 12:55:23 GMT 2006
239 - Allow additional key => value pairs as arguments to the
240 ZOOM::Connectoion constructor; these are added as Connection
241 options before the protocol connection is forged.
243 1.02 Thu Mar 9 11:36:55 GMT 2006
244 - Add interface to yaz_version().
245 - Emit big warning at startup time if YAZ version is less than
246 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
247 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
248 - Fix incorrect ZOOM-package URL in documentation.
249 - Fix typo ("createdb" package) in documentation.
250 - The ZOOM::Connection constructor may now be called with only
251 a single argument (host-string) and does not require a
252 dummy port-number argument.
254 1.01 Thu Dec 22 14:13:34 GMT 2005
255 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
256 so that the declarations they begin with are at the start of
257 the block. This avoid mixed code/declarations. (The
258 "correct" solution is to use INIT: clauses in the XS file,
259 but they don't seem to work: the code in them is slapped
260 down right next to the CODE:, so declarations are not
261 acceptable there either.)
262 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
263 uses a query object to indicate the start-term. This opens
264 the way for using CQL queries for scanning once the
265 underlying ZOOM-C code supports this.
266 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
267 method scan() is renamed scan_pqf(), and a new scan() method
268 is introduced which calls the underlying scan1() function.
269 Thus the scan()/scan_pqf() dichotomy is consistent with that
270 between search()/search_pqf().
271 - The tests t/15-scan.t and t/25-scan.t now also test for
272 scanning by CQL query. To support these tests, a new files
273 is added to the distribution, "samples/cql/pqf.properties"
274 - Remove nonsensical clause about CQL sort-specifications from
276 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
277 client-side CQL compilation.
278 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
279 compiler functionality as a Query subclass.
280 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
281 returned by the client-side CQL facilities.
282 - The test-scripts t/12-query.t and t/22-query.t are extended
283 to also test client-side CQL compilation.
284 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
286 - Add new ZOOM::Log class for logging, providing aliases for
287 the functions in the Net::Z3950::ZOOM layer.
288 - Add diagnostic set to rendering of Exception objects.
289 - Documentation added for CQL compilation and logging.
291 1.00 Wed Dec 14 11:18:33 GMT 2005
292 - First distributed version.
294 0.01 Fri Oct 7 16:14:20 2005
295 - original version; created by h2xs 1.23 with options
296 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
297 --omit-constant --skip-exporter --skip-ppport \
298 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
302 To be done in future releases:
303 - Complete, test and document "update.pl"
304 - Create old-style Net::Z3950 compatibility layer.
305 - Fix memory leaks in callback functions for option sets.
306 - Fix limitation that option-set callback functions must be
307 specified as strings containing package-qualified function
